    this room look commonly called tot.nhung has a thing is not like that which is very cost Ram.2 days to restart the phone.

  • Karol

    it’s a very good rom… tested for 2 days. I think its better than RR 3.0.6 in some cases. It’s very fast and has TW 5 on JB (awsome). It comes preloaded with good apps like Power Sawer, Walkman, polaris office, solid explorer, etc.
    I Use it as Daily Drive. I previously used the RR 3.0.6 but my phone restarted 5 times a day.

    This ROM:
    + Very fast
    + 5 launchers
    + Nice theme (x2)
    + No FC or restart phone
    + some good apps from stock ROM like polarisoffice, samsungApps
    + good batery life
    + can’t find any big bugs (for now)

    – absence swipe keyboard
    – absence radio
    – absence TW wallpapers
    – absence callrecorder
    – Xperia launcher sometimes not working well

    good job….

    • aldous

      after reading your post, I recognised I had downloaded the ics thunderbolt instead. Since both the ics and jb versions are on this website and they have the same filename, can someone rename the JB version accordingly, please?

  • aldous

    What differences with regard to installing dream or syiah kernel? Syiah drained the battery faster in my previous experience with a different rom.

  • Farhan

  • Blazingstar75

    no service with this rom, and com.android.phone stopped accessing APN settings

    • Anuj

      Yes even i agree. Edge doesnt work.

  • Jason Stewart

    I had HUGE problems with this Rom. But version 3.1 is out now and that seemed to fix most of them, even comes with ota updater. So far working good.

  • aldous

    I’ve reverted back to RR JB ROM. The present thunderbolt JB turns phone off when it’s not connected Online; It says “.com.android.phone stops” whenever APN setting is clicked on.

  • brian

    ok had this 4 days now and almost flawless, ive tried every god darn rom available and this is a keeper for now fast slick not butter smooth but almost.

    cant reccomend this rom enough, thanks to Mo πŸ™‚ this is the real deal.

  • JON

    The bluetooth works but it is asking my for me to enter a code on my computer – which it is not popping up with a code box.

    My worst problem with this is I cannot control the S2 on the car dock, audio is only coming through phone speaker and this is very annoying, seeing as I just purchased the official S2 dock from Samsung. Tried a couple of fixes, but no use … the dock setting on the ROM is grey and cannot be modified.

    Tried and App from Play and it had this info:

    Please have the CM dev supporting your model verify the correct mapping exists between the ROM audio device and the kernel audio path (commonly set in libaudio).

    Example: DEVICE_OUT_ANLG_DOCK_HEADSET in ROM should map to the path PLAYBACK_EXTRA_DOCK in the kernel.

    I hope that can be remedied soon in a patch/apk update??

    • merin

      I too not able to play in car audio, it connects but sound comes thru phone speakers

  • androsland

    i mean, is eclipse able to detect the device and load your app on your mob?

  • armin

    plz guys help me I cant use my external sd πŸ™

    • Max

      erase .nomedia file in your sdcard.

      • Alsden

        Hi Max,

        I agree this is by far one of the best JB ROMS I’ve used, but I too have the issue with music not being seen by any of the apps (Walkman, Play Music, Music, Apollo and even PowerAmp) On ICS, I had all my Music on my External SD Card and it always automatically available on any music app I installed.

        Where is this “.nomedia” file? and also is there any truth to the SD Card’s format being wrong? (Although I can still see all my music and play it if i go through a file explorer) I just want to know how to get my music in my SD Card to show up in the library of the music apps…

  • larry

    hi, may i know if i am able to flash this rom, then flash dorimanx kernel over it?

    • Max

      yup. you can do that.

  • Prajesh Solanki

    Not sure what all the different Kernals do.
    But I tried the Siya Kernal.
    I quite liked this ROM, the different launchers etc.
    The Xperia ROM doesnt seem to work fully and the Xperia process shows as stops responding sometimes.
    Plus on a few occassions (about twice or 3 times) I have noticed that the screen colours screwed up/inverted but a reboot sorted it. Not sure why that happened.

    Battery life? seems to be a little draining but doesn’t seem any worse than any other ROM.
    I’d say this is a good ROM and one to definatley try out. My favoutire launcher has to be the APEX laucher.
    Havent noticed any major issues except if you want to overclock, then reclock the CPU back to normal settings – both sliders move when you move the minimum CPU speed.

  • Andy

    Hi,
    Does any one experience any problems, changing the rigntone or notification sound?
    I get an error “Unfortunately, the process android.process.media has stopped” when click on the phone rigntone. Use Apex launcher may a problem with it, not with the ROM itself? Any ideas?

  • Andy

    Ignore previuose wrong post

          • Strictly.Mobile

            Ali, sorry to hear about your troubles, if you can’t get your phone to power
            up, get into recovery mode or even download mode, it’s not looking too good.

            If you can get your phone into download mode by holding volume down,
            home and power together, I would flash a stock rom from link below…… http://www.sammobile.com/firmware/?page=3

            Flash using odin with appropriate cf kernel from……….
            http://forum.xda-developers.com/showthread.php?t=1103399

            If that works then get cwm rommanager on your phone
            and try flashing the rom of your choice again…….

  • Strictly.Mobile

    I’ve flashed a few roms but this one takes some beating, very easy to install following instructions, i’m currently running with Dorimanx kernel v7.8. Even thou I did have a few issues, it was very easy to fix, firstly the xperia launcher was crashing, l kept getting a pop up window saying xperia had stopped working, so I installed Root App Delete from Play, froze the launcher, then deleted app. I then had issues updating gmail, google+ and youtube, so I followed the same process with Root App, then reinstalled from play without any problems. I am now very happy using v5 across 3 launchers, no real need for using the dual boot option and I can’t wait to get a look at v6.

  • Farhan Abbas Khan

    @ali Download resurrection remix rom in to your external SD card than reboot in recovery mode and select that rom you downloaded and follow the instruction … its the best rom I have used … google resurrection remix and download from thier website

  • Ryan Wiblin

    I flashed this Rom last night. I have been running older versions of thunderbolt for quite some time. Its a great Rom..
    But,
    I do have one problem though…
    I don’t know much about flashing different modems and last night the aroma installer prompted me to choose a modem… I just chose the first one…
    But the data throughput isn’t that great… it’s quite slow and doesn’t really work most of the time..

    I don’t know what modem I should be using and don’t know if I can flash a different modem or where to even find different modems….

    HELP?!?!?!?!?!

    • philcole4321

      I do not recall seeing any options in the Settings to change the modem. You may have to try reinstalling and choosing another modem when to get that option. Before you do that look up what modem your stock software used and choose that during setup.

  • Joshua

    I’v got a problem with the sound from my headphones, they are very low on Aokp, and cm10. Does this Rom fix this?

    • Cosy

      I’ve noticed that too with most AOKP Roms. It’s not THAT bad but it is noticeable.

  • Sam

    I have flashed my S2 with thunderbolt… but I am facing problems with Data connection. It doesnt seems to connected. I have reset the APNs as well… Kindly help… what I m missing ?

  • Cosy

    Love this rom. The only issue I’ve had is that the data and wifi have a tendency to drop out every so often. Aeroplane mode off and back on again sorts it out. This isn’t that often.

    Fantastic smooth rom with no freezes/crashes or random reboots.

    Kudos Dev and thanks Max.
