  • carol

    Thanks, Carol

    • Alex Gonzalez

      you just need to go to tmobile and upgrade your sim card its free

  • carol

    Is there wifi calling on rooted galaxy s2

  • carol

    Will rooting interfear with update due out Nov 13

    • jeff

      yea i dont think u can get more updates after rooting but just flash a custom rom with wifi calling in it. also if u must and absolutely have to theres an unroot method on here. personally i would never unroot

  • Tom

    i have a t-mobile galaxy s2 …i just installed batista70_3.7.4_by_Snakes Rom after reboot the system the phone wont turn back on again plz help….thank you..

    • androider

      im having the same problem. no one replied…HELLLP!!!

      • Lejojaluel

        The Rom must be corrupt so either use a updated version one or diffrent rom.

  • Patricio

    Instalaste una Rom que no funciona con el Samsung Galaxy S II de T-Mobile, esa rom (batista) es para el i9100…
    Si el teléfono se enciende tenés suerte…

  • Tommy

    I just want to get rid of the tmobile bloatware. Can I just simply uninstall them or delete them after rooting? or do I have to install a rom? Thanks for all your help ^_^

    • Daring_Guy

      Once you root the phone, you can get rid of the bloatware by installing Titanium Backup and Deleting them from there. I rooted my phone last night just so I can remove the Bloatware that TMO puts on the phone. However, I did take a backup of all the apps on the phone (again using Titanium) just to be safe in case I deleted something that should not be 🙂

      I like how the list of currently running apps on my phone has gone down and the phone is much faster than before!

      Good Luck!!

      • joe

        what bloatwear aps can i remove to make it faster??? i removed books and some other junk but it still is not much faster and the battery dies just as quick as it did unrooted, i tried to install a new rom that was recommended and it bricked my phone so i just went back to the unroot i installed.

      • MikeD

        I have the Telus version T989 Galaxy SII X…. is there a safe site to root my phone? I have already loaded ICS 4.0.3 and want to get rid of the annoying bloatware as well

    • Jack

      can I unlock my tmobile galaxy s2 g4 so that I can use it on other carriers around the world.

      • Lejojaluel

        No thats retarted -.-
        Thats pirateing in a way…

  • Tk

    hey hey.
    thnQ 4 this website. it hellped me a lot. however, im still stuck with one issue and couldnt solve it yet. how to take the language support from the international version to the tmobile version (Arabic support)
    hope u can help me with this or give me some advice.

  • Mohamed

    i have T-Mobile SGH T 989 wanna asked about nomination from you for the best kernel in your opinion (which you prefer to use always )

    • Jonathan

      I currently use Paradox Paradise II with Beats theme and I have found that it has the best functionality. Other ROMs including Tuesday New Beginning, SlickMOD, and Juggernaut all have different problems. Most of them don’t support swype and others have google play store download issues and gmail sync issues.

  • DK

    Just wondering if Juggernaut 3.69 ROM is very stable and hows the battery life?

  • Keshaun

    Hi All,
    I am a little concerned about the Carrier Iq on my stock T mobile Galaxy 2 and I was wondering what is the best option for me to remove it.

    I like my touch-wiz interface a lot and would like to keep that intact but I want to remove the CIQ. I see there is a T-mobile Stock ROM that is provided but my question is if I re-install that stock rom if I can remove the CIQ with the superuser permission.

    Thank you in advance!!


  • raghu

  • Jerry Angel

    buying a new tmobile galaxy s2 phone – want free internet tethering and if possible wifi ghot spot. Can i pay you and send you my phone to make sure its done correctly? Please advise

    Thank you
    Jerry (727-992-5777)

    • Malcolm Sequeira


      There is a free app called FoxFi that will turn your phone into a hot spot – as far as I know, t-mobile $15 per month charges do not apply.

      I hope this helps.


  • rick

    Hi i updated T-Mobile Samsung Galaxy S2 to androind 2.3.6 with wifi calling and it took out the root after update so how can i Reroot back any idea please help really appritiate

    • Nilson

      Same happened to me and I need to root also

  • william

    can u use the bombaridier kernel on the domination ics rom?

  • Loco

    I want to root the phone so I can use it as a Mobile WiFi without paying the bs newly added outta nowhere $15 fee Tmoblle wants.

    Its a toss up as I still need the WiFi calling capability but I also still want to be able to use this as a free mobile hotspot.

    Anybody gotta rom that can do both?

    • Malcolm Sequeira

      Free app called FoxFi will do this.

  • Rosciae

    Does anybody have a easier way besides Unrooting to be able to update their t mobile galaxy s2? I really enjoy having my phone this way but i really want to update the phone so the stupid update reminder doesn’t keep coming on every time i turn on my phone.

    • ArmyStrong

      See recent comments on another part of this site to anwer your update question:

      Also included are how to uninstall (or freeze) the update “Device Manager 3.0”

    • tmo

      Dont do the update….it unroots your phone, could worsen battery life, and I read that it has more carrier IQ software attached.

      Use Titanium Pro to “clear data” in the Device Management app, then use Titanium to “Freeze” Device Management……There will be no more notifications and the notification icon will be gone. Its what I did…it works.

  • Tak Tak

    I updated to 2.3.6 now lost root access. What can I do to root the phone again?

    • Barmal

      I have similar problem. Waiting very impatiently to root Tmobile galaxy s2 2.3.6. It appears that there is no way yet to root this device.

      • Jay

        I ran through the procedure again using su-3.0.7-efgh-signed.zip and it worked for me.

        • Barmal

          Thanks Jay. Yes that works with super user 3.0.7 after a few tries. Somehow it worked for me when I repeated the whole process at least three times if not more.

  • tmo

    I wouldnt delete apps after rooting, just freeze them with Titanium. Its safer.

    Also, can we please get a guide for removing the Carrier IQ spyware from the Tmobile SGS2.

    I have gotten root, but I am new to this

  • Vanawesome

    How can you root it on OSX lion? Please please please please please do a video on this! I have installed and tried to figure it out using heimdall, but I am totally lost. Thanks!

    • rugar

      you got a freakin android and still have a mac,get serious dude either upgrade to PC or downgrade to iphone

      • Scuba

        Upgrade to a PC, really? Mac is way better, and Android is way better than iphone. Just use virtual box to install a windows virtual machine on your mac and then you can do anything you could do with a PC and still use you fabulous mac.

  • celloman

    So far I’ve tried both the Eagles Blood and ICS Roms on this site, all worked great- except no wifi calling. Are there any custom roms for GS2 that support it? There’s no mention of it on the site. This is something you should include in the rom descriptions.

  • ahmed

    i just want to know if i can install fonts cuz i cant read arabic and this device doesnt support it but sometimes i can read specific arabic font

    • lamy

      install opera mini you willread arabic , then ibrahim arabic keyboard you can type arabic , this is the easiest way , the other way is to root your mobile

  • Marc

    Is there any 2.3.6 Rom for the Tmobile SGS2 that has a stock kernel ?

  • seba laus

    Odin isnt even opening for me.

  • Loco

    any ROMS that have WiFi Calling and FREE (possibly untrackable) WiFi Hotspot???

  • Funsack

    Will someone please let us know how to root T-Mobile gs2 using Mac OSX? I’M the 3rd person to ask. HELP! PLEASE!

    • rugar

      you got a freakin android and still have a mac,get serious dude either upgrade to PC or downgrade to iphone.

    • Rob

      You need to drop the Mac, don’t even try this with a Mac, get a PC so you can join the adults, PC = Android : Mac = Iphone.

  • Anthony

    Hi Evryone,
    Is there anyone knows a link that I can download the Beastmod Rom Ii 3.5v?


  • Joshi

    I am a Linux user (Ubuntu). Can someone please share some instructions on how to root using Linux? I saw instructions on this site for Linux but that is only for AT&T version of galaxy s2. It seemed like all you need to do is to use a different image with heimdall but there was no pointer to appropriate heimdall image for t-mobile.

  • jose aguirre

    i had a question i just install a rom but from the at&t roms to a tmobile s2 but now it dosent want to turn on..what should i do ???? pls help!!!

  • kaybee

    Hey there,

    I recently loaded a custom ROM on my SGS2 SGH-T989 and I forgot to backup the stock ROM, I was wondering if you had the stock ROM and everything stock for the SGS2 SGH-T989?

  • Ben Hulet

    Once the T-Mobile Galaxy S2 is rooted, does the SuperUser Icon remain. How would I remove that and still keep the phone rooted?

  • BBH

    Can you please remove my last comment?

  • Dan Howell

    I went through the root procedures on your video and thought I followed the directions correctly. everything seemed to follow the video. After a final reboot, I downloaded titanium backup and the error message ” sorry, i could not acquire root priveleges. This application will not work. please verify that your ROM is rooted and includes busybox and try again,”

    Can you help me with what I might have done incorrectly and how I can correct it.


    • ledion

      Root it again because ur phone its not rooted

  • omri

    i rooted my t mobile and started erasing stock software with titanium back up but i accidently erased the task monitor file and now i cant view and close running programs.
    what do i need to do to restore it?
    thank you

  • Daniel

    I’m not exactly a newbie but I’m still a bit shy of doing all this. I *HATE* losing data when I do these things… it equates to losing time.

    I have already rooted my phone (Thanks 100% due to the video here on how to do it. It actually worked better for me than on the video! I got NO errors) and I am interested in trying a new ROM. But I don’t want to lose any data. I want to keep my call block list, my contacts with pictures and all that, my angry birds scores, my stupid zombies scores(!!) and everything.

    I would really like to see a comprehensive list of steps that describes everything in detail. We always see “back up your ROM” but I never see anything about data backup and restore. For me, using the phone is more about the data than the operation of the phone. My experience with Vibrant left me reluctant to do ROM upgrades because of the data loss issues when upgrading. I just want to be able to bring my data back.

  • Manuel

    Any roms with vlingo removed?

  • Daniel

    Will the sgh-t989 get ics soon?

    • Gabriel Roman

      samsung is still testing…..were still waiting

  • Lewis

    How do I download tmobilegalaxys2root.zip?

    • Gabriel Roman

      I download alot of files from akaskriller for the Galaxy s2 like the Odin,Root.zip,ext but the best website for Roms will be this one

  • kiet

    do you know how i can increase the speed on the 4g mobile internet? i keep getting 3mb while my friends get 20+mb. thanks!

    • Gabriel Roman

      click menu
      wireless and network
      Mobile Networks
      Network Mode
      choose WCDMA only
      u wont get Edge or 3G any more Enjoy

      • Guy

        Any idea where this setting or its equivilant is in ICS?


      • Ryan

        It wont let me select WCDMA only, keeps it on automatic.
        What is the way around this?

  • John Voss

    I just did that trick and I went from 6mps per sec to 8 accroding to speedtest. what’s the catch?


  • Will

    I have rooted following the video. I flashed clockworkmod and am able to install some roms, but most roms i’m getting bootloops even on the skyrocket port. Someone please help me

    • Ryan

      I have the same problem on the new ICS rom, and the Black rom.
      The only one that passes the boot stage is the Malice rom.
      I would like to try some new ones!

  • Guy

    Anyone find a way/Kernel to OVERCLOCK the T-mobile variant of the Galaxy S2 that has a PORTED ICS ROM on it?

    I have seen many Gingerbread ROMs overclocked and tried many of them myself! However, I have not seen any for the ported ICS ROMs. I am so eager to see how well it does!

    Any ideas or assistance would be greatly appreciated!

  • bob

    So is there a way to root on a Mac or not? I don’t want to hear any ignorant comments about which computer system is better. Android and PC are more customizable, Mac and iPhone are more simplistic. I like simplistic computers and more complex phones. So I will buy accordingly. buy what you like. Don’t be stupid and try to convince people what to like and what to but.

  • Awad

    edomax ,

    I did all what you said,

    1-I rooted the device.

    2- I make a backup using root manager and Titanium

    3- I downloaded both ROMs (SGH-I727-Port-To-SGH-T989 & icsmegamixv1.22)

    4- Both of them does not work , I don’t know why the instillation successful but when I reboot the device it gives me the logo At&t the it repeated many times then it is hanging.

    Please help me to fix it, and I don’t know even how to return to the original one

  • Artur

    i did all the stuff you guy’s said to do the SGH-I727-Port-To-SGH-T989 update, downloaded all the apps and followed all the steps. when i reboot my galaxy s2 in the end off all steps it starts the “intro” of AT&T and started to lop auto reboot, now it dont turn on the screen , but when i plug the usb the odin says that is conect (i had to download the QHSUSB_Drivers_(x64) to do it)
    can you help me?

  • John

    Hi I have a gs2 by T-mobile sgh-t989
    With stock Rom only root and ever since I rooted the phone the Google play store will not work it always says force close when I try to select an app. If anyone can help me please fix this issue I would really appreciate it. Thank you

  • Johan

    Hi my friend:

    I’m new to this of rooting, but I have a doubt, I have already rooted my t989, and I wondered, if I have my phone rooted will I be able to install 4.0 Ice Cream Sandwich when is available?? Or I have to unroot and root again???

    Thank you very much!!!

  • Eric

    Tried to download a custom ROM. Was all good until I extracted zip file. Reboot went into loop and phone freaked out. I was lucky enough to do a data wipe and restore with my cwm. Anyone now what went wrong?

  • nick

    Hey guys I have a custom rom on my gs2 and i was wondering could I still get the software update for ics which is comming tomorrow?

  • Gs2Gunzzz

    i crrently have a rooted s2 running the darkevolution ics rom 4.0.3….. kernal 3.0.8-perf-t989uvlc8…
    ive heard the term overclocking, and was wodering if anyone had any thoughts on if this would make a big difference or not. if so… is there any suggestions on particular kernals. iam kind of new to all this, so any help from you guys is greatly appreciated.
    thanks, Gunzzz

    • admin

      There’s no overclocking available for ICS on T989 yet, we have to wait until Samsung releases their kernel source code.

      • Eric

        Update your radio to the UVLDE radio. I was getting forced close all the time and this fixed it and my phone seems faster both wi-fi and data.

      • Gs2Gunzzz

        Ook well I ran quadrant on my device and ended up with about 3350as a total… Would u say that is good or not.

  • Gs2Gunzzz

    When checking into the radio upgrade… Inoticed that it said unknown under baseband type… On my phone. Any ideas?

  • Tom

    I got the unlock code from the third party and did the unlock of my T-Mobile Samsung Galaxy S2 and it was successful. However, when I try using my AT&T sim and after rebooting, it identifies the AT&T sim initiall and within few seconds it goes away and it turns into Searching..
    Any idea? What I can do to overcome this?

    • admin

      Sorry, Heimdall doesn’t support T-mobile Galaxy S2. Heimdall supports all other GS2 variants though this is due to the chip change in Tmo version.

  • Richard A Chandler

    I tried to follow the instructions you gave in your youtube video at http://www.youtube.com/watch?v=lfA1KKzXkFU&feature=relmfu. The result so far looks like an unmitigated disaster. I’ll probably have to get a new phone. Everything went as expected, until I tried to install “clockwork mod recovery” as you described at 3:39 in the video. I tried to install the “recovery-cmw-hercules.tar” file, but it failed three times. The phone would not reboot. I left it there for an hour, with a warning sign on it about not disconnecting the target. Not sure what that means, but of course I had to disconnect the USB cable eventuallly. Now I can’t start the phone. The message says “firmware upgrade encountered an issue … Please select recovery mode in Kies & try again.” What? All I have in Kies mini (the full Kies doesn’t work on US phones), and there is no recovery mode. My phone is a brick, I have no idea what to do. Help!
    P. S. Am I the only one who couldn’t make this work?

    • Max

      That’s perfectly fine, the Kies error is same as ODIN download mode, just flash the file again in that mode, voila you have it working again.

      • Richard A Chandler

        I’m sorry, but I don’t follow you at all, it’s like you’re speaking Klingon.
        First of all, when you say “the Kies error,” what do you mean? I wish I could send you a graphics file … but when I try to start the phone, I see the message “firmware upgrade encountered an issue … Please select recovery mode in Kies & try again.” Is that what you mean by “the Kies error”? Or do you mean something else, some message I’d get when running Kies? If the latter, then I’m really hornswaggled. Last night I did download the full version of Kies, but I can’t do anything with it. I see a little icon on the upper left that whirls around, indicating that it’s trying to connect, but it never connects, nor does it ever say it can’t connect. Connection troubleshooting does not help. Nothing happens when I try to update the firmware.
        So I hope you don’t want me to use Kies. But then what in the Sam Hill do you mean by “flash the file”? What file is that? The “recovery-cmw-hercules.tar”, or something else? And what is “flashing a file”? I’ve heard of opening files and modifying files and executing files, but the phrase “flashing a file” means nothing to me. Is “flashing the file” something I do with the phone connected to my PC, or not connected? I guess it doesn’t matter, because I can’t do anything at all with the phone either way. I can’t even turn it off, except by taking the back off and removing the battery. If I push the on-off button on the left, nothing happens. If I push the volume buttons (up, down or both), nothing happens. If I push both together for about 10 seconds, the screen will go blank for a second or so, then the same message reappears. That’s the only blessed thing I can get the phone to do.
        I did try running Odin again. I got a yellow field “ID:COM” saying “0:[COM7]”, I checked “auto reboot” and “PDA,” pushed the PDA button and chose “recovery-cmw-hercules.tar,” then pushed “start.” I got a message saying ” All threads completed. (succeed 0 / failed 0)”. And I’m right back where I started. The phone does not reboot, I can’t install that “clockwork mod recovery,” I’ve never seen a screen that would enable me to do that and I’m not sure I’d recognize it if I did.
        Wait, I tried pushing “start” again, for a second it looked like something was happening … then the square above COM7 lit up red and said “Fail!” (yes, including the exclamation point). Here’s what I read in the message field:

        All threads completed. (succeed 0 / failed 0)
        All threads completed. (succeed 0 / failed 0)
        Odin v.3 engine (ID:7)..
        File analysis..
        Get PIT for mapping..
        Firmware update start..
        NAND Write Start!!

        Complete(Write) operation failed.
        All threads completed. (succeed 0 / failed 1)

        … and now I’m back where I started. Phone still does not reboot. I just tried pushing “start” again with exactly the same result, that is, the error message above and no other result at all.
        Apparently you understand something that I just don’t see at all. Do you think you can tell me what to do in a way I can understand? If you can, I’ll send you $100, I’m serious, my only alternative is to get another phone. And to think all of this was because I couldn’t get a GPS fix … do other phones have problems like this? Maybe I shouldn’t have gotten this phone anyhow. I notice the battery life isn’t so good.
        I’m rambling on and wasting your time, thanks for your help. Kindly, R

        • Richard A Chandler

          I finally left the phone connected long enough that Kies stopped trying to connect. A message came up saying “device not responding, reboot the device.” If I could do that, I wouldn’t have a problem at all. Kindly, R

        • Max

          Just re-run ODIN in Kies firmware mode, it will work. Make sure Kies program is not ON, turn it OFF.

  • Richard A Chandler

    Thanks but … I still don’t understand. Not to run Kies, that’s simple enough, but run ODIN in Kies firmware mode? There seems to be only one mode of running it.

    I do not see any pull-down menus. All I see on the top is an icon and the words “Odin3 v1.85”. Then there’s a banner reading “Epic 4G.” There are 8 boxes underneath, all empty. Under ID:COM, there’s one yellow field with the label “0:[COM7].”

    Then I see some check boxes grouped together as “options.” They are labeled: Re-partition, Auto reboot, F. Reset Time, and Flash Lock. I checked “auto reboot” as your youtube video indicated, but no others.

    I see a field labeled “Control Panel” with two buttons, “Start” and “Reset.” I pushed start when I started; they are now ghosted out.

    I see a field labeled PIT It’s now ghosted out. I’ve never done anything with that.

    I see a field labeled “Files [Download].” There are 4 checkboxes with buttons and blanks. One says “bootloader” (I didn’t check it), one says “PDA” (I did check that, pushed the button, and opened the file “recovery-cmw-hercules.tar” as your video led me to do). I see one saying “Phone,” but I didn’t check it, and one labeled “CSC,” but I didn’t check that either. Then there is a field labeled “File [Dump]” with a button and a blank, but I have never done anything with that.

    Finally, there is a “message” area. It currently reads:

    Odin v.3 engine (ID:7)..
    File analysis..

    … and it’s hung up there. It’s been hung up at least 15 minutes and shows no sign of doing anything.

    That’s absolutely all the controls that ODIN offers. I even tried right-clicking everywhere to see if some new menu would come. I don’t know what you can possibly mean by “firmware mode.”

    Do I have to download something else, firmware perhaps?

    Kindly, R

    • Max

      Not sure but I think you are digging too deep, the only things you should touch are “PDA” and “Start” button.

      Try another computer, it could just be some drivers on your computer interfering, fastest solution to your problem, otherwise you will waste more time trying to figure out what’s wrong.

      • Richard A Chandler

        If I understand you, you’re saying that I’m already in “Kies firmware mode,” and I’m doing everything right? My screen says “firmware upgrade encountered an issue,” but you say this is the same as if it said “downloading”? I just tried it again, same result.

        I’m really not sure what, if anything, I’m doing wrong. I’ll try it on another computer.

        Here’s a few things that I don’t think should matter, but maybe you’ll know better:

        1. I took out the SD card that I got from Samsung and started the root process with a different SD card that I’d just formatted. I figured that would protect the data on that other SD card, which includes apps as well as music, books, etc.
        2. I’m using a laptop running Windows XP 64. My wife’s desktop uses Windows 7, maybe that’ll work better.

        Kindly, R

        • Max

          Yes that’s same as Download Mode, try your wife’s it should work fine.

          • Richard A Chandler

            Well, failed again.
            I transferred (by a flash drive) the zip file “tmobilegalaxys2root(1).zip” and extracted it to the desktop of my wife’s computer, which runs Windows 7. I installed ODIN, then attempted to hook up my Samsung phone.
            Windows complained that it needed drivers, so I downloaded Kies mini and got the drivers. When Windows was satisfied, I ran ODIN. It failed exactly as before, except that I’m using COM 3 this time. The message read:
            Complete (write) operation failed
            All threads completed (succeed 0/failed 1)
            What now? Kindly, R

            • Max

              Make sure Kies is not running at the same time as ODIN, maybe that might be why.

  • Richard A Chandler

    Oh, I noticed when I downloaded that ODIN program, I unzipped it, only to find another zip archive inside it. I transferred that zip file to my SD card. Was that the right thing to do? Or should I have unzipped it, discarded it? Just seems odd. Kindly, R

    • Richard A Chandler

      Maybe I should also mention, I removed the SIM card from the Samsung phone and transferred it to an old phone that still works. Should I put it back in the Samsung? R

      • Richard A Chandler

        I tried again. My wife’s computer now fails to recognize my phone. I tried running Kies again and installed the drivers, but windows still doesn’t recognize it. ODIN won’t find a COM for it, either. I can’t do a thing.
        Kindly, R

        • Richard A Chandler

          I’ve tried a bunch of times on both computers, always fails. If you suggest anything else, I’ll try it. Otherwise, tomorrow I’ll try to unbrick it, and if that fails, I’ll cough up several hundred dollars for a brand new phone and count it an expensive lesson learned. What would you recommend, for a new t-Mobile phone? Kindly, R

          • Max

            Hmmm make sure Kies is turned off, kill kies in Task Manager and try again, should work bud.

  • Mike

    I rooted my Galaxy S2 T-Mobile phone so I could enable wifi tethering. I currently have Gingerbread on my phone. T-Mobile has sent me an update. I can’t get it to stop reminding me. If I run the update will my phone need to be rerooted? Does it matter if I just don’t update? Can I stop the reminders?

    • Max

      its a tmobile ICS bug, you have to use Titanium Backup app to remove device management app to get rid of notice.

      • Mike

        But what if I do want the update? Can I somehow update and will the phone still be rooted after the update? Thanks for the help!

  • Steven

    i just switched to unlimited 4g with t mobile. Does anyone know if t mobile will know if i use wifi hotspot when i im not suppose to?

    • Mike

      I have unlimited 4g with t-Mobile. No they will not find out. Just a heads up though about “unlimited” . It means unlimited internet and not unlimited 4G. I wasn’t clear on this (maybe you are). I was using the hot spot for my iPad and like watching shows on it when I traveling a lot for work. One day I got a warning text that I had used 4.5 GB of my 5GB of data. Then when I hit 5 GB an auto text told me that I’ve used up all of my 5 GB of high-speed web access. and my speed was being reduced until the next billing cycle. It gave me an option to upgrade to 10GB of data at a much higher rate. SO … If you if you plan to watch a lot of streaming video it will eat up your data limitation before you no longer have 4G speed. The speed goes so slow that I can’t even entertain the idea of even seeing a youtube video on my phone. I could still do emails, Facebook etc.. but slooww…. On months when I used it only for web pages and emails 5GB of data was plenty. Just be warned that if you plan to watch a lot of video you might want to pay for 10GB’s of data.

  • Steven

    any answers to my question before?

    • tom t

      Hi Lee, It is odd that I am having the same problem but only inside my home where T-Mobile service drops to 2G. Same phone behavior that you have. When I move outside where I can pick up 4G, even with 1 bar, call quality is good again. Although I rooted about 2 months ago, this problem showed up about 3 weeks ago. I think this is service related, not a rooted issue. Max, would you agree?

  • June

    i have galaxy hercules t-mobile (T989) and currently on the stock Rom T989UVLH1. However, i found out that there is no chinese language under the language selection. I have tried the Miui Rom or theme as well, and CM10 or 9. they all have Chinese language pack in the system. However, those custom Rom have some issues which i dont really like it at all. error sometimes happens. I also have tried those apps such as locale and morelocale2. they dont give me through chinese especially in the system setting or error message which all are in English language. is it possible you can show me on how to extract the Chinese Language out from other firmware and put just the language into this device? or how to put the chinese language pack into the rom so it will make entire interface to be Chinese in language?

    now, some google searches found me that at CM10 is working on it, and at XDA there is not a whole lot said about it.
    Do you know, or somebody else, know about future plans on fixing this?

    Hello. it is sunday and I have wanted to root my tmobile s2 for some time and went to the s2root site and followed the instructions. So far so good but when I ran an update for super su the program could not run. i downloaded the titanium backup and it also said the phone was not rooted. i thought i would drop you a line later but started messing with the cwm and did a data wipe and reset now the phone just reboots over and over. I can still get into cwm, just need some advice please. actually this is pretty cool getting into this phone like this. I want to try other roms for sure. I have a note 3 that I want to root also but my original s2 is my test phone. Any help would be appreciated. I know this is fixable as I can still use the cwm. I dont care if I put a new ROM on it at this point either but the fact that the phone showed it not to be rooted is of concern. When I downloaded and installed titanium backup i did not open it up from the actual install window so did an uninstall and installed again from the install window on playstore but still would not work. Thanks.

    Hello there! First off, thanks for all the information and help you have provided on your website. My concern is for my T-Mobile Galaxy S2 SGH-T989, ever since I upgraded from gingerbread 2.3.6 to jelly bean 4.1.2 rooted, the google play store has not work. It says “unfortunately, “google play store has stopped” I switched and installed the unrooted version of jelly bean 4.1.2, same problem. I have done the “force stop” and “clear data/cache” to the downloads and google play store apps, and even reset app preferences, but nothing yet. So how can I fix this, what else can I do?

    Help!!! So, I had upgraded my unlocked T-Mobile Galaxy S 2 (SGH-T989) to jellybean. When I was going to give it to my son, I reset it to the factory conditions to wipe it clean (I now know that was a bad idea)…….it it got stuck in a start-up loop. I tried the factory recovery & upgrade and now it won’t even power up. Any thoughts? Can I get into it to restore the firmware if it won’t even power up?

    Hi, my t989 suddenly went into so called bootloop actually the phone stuck on Samsung logo after it passed t mobile & android screen. Currently the phone is running stock JB.

    Some history, the phone is a little weird when it was running ICS so I decide to update to J JB and it seems the problem is fixed but creates some other minor problem. 2 weeks ago When the phone battery is low, I decided to change to a fully charged backup battery, then soft brick Jay happened.

    What I wanted to do is to preserve the phone data or extract it out before do a clean wipe or use Odin to recover.

    By searching and reading all the forums that I have tried few things. At least I know that
    Phone can boot to
    Download mode

    I can use ADB to reboot the phone but when I try to extract the data by using ADB pull didn’t seem working well? (wing directory, I assume)
    Is there a way to do Nand backup at this state?
    If I use Odin to flash the stock room. What happenedhappened? Data got wiped?

    Send like if I flash the kernel might fix the problem? But what kernel I should be using?

    Thanks for any help, I am out of country right now, desperate to the info out of the phone (the stupid phone die before I board the plane)

    Thanks again
