For those of you who want to try out the latest official Jelly Bean Firmware for your T-Mobile Galaxy S2 SGH-T989, you don’t have to unroot, which will force you to root your phone again.
Instead, there’s a CWM flashable zip file, this is completely stock firmware with root added and you won’t lose your custom recovery as it’s packaged just like a regular, custom ROM.
You can grab it here:
[Fixed!] Download T-Mobile Official Jelly Bean + Root, mirror
To install, reboot into recovery, wipe data/factory reset (unless coming from stock or stock-like ROM), install ROM, and reboot.

I tried the update to jb with the cwm and root and ended up with a boot-loop 🙁 I’m doing the original way through keis because I can’t wait but just thought I should let you know I had trouble with the cwm+root method.
I just tried this need to do a darkside cache wipe they boot but is really slow
How did you resolve the sluggishness after successfully flashing?
All seems ok except the phone does not work. Anyone else having this problem and is there a fix?
You might want to try flashing your radio to UMVC6. I searched for ‘sgh-t989_uvmc6_radio’. After flashing my phone and data works perfectly.
Everything works smooth but no network access for data or phone. This is more like the official-unofficial release.. The lock screen is still the annoying t-mobile look. Flashing back to CM 10.
Also want to add that it doesn’t recognize my sim card and also Google Apps didn’t apply after flashing the 4.1.2 version.
A rom that does not recognise the sim? Who would release something like that or are we doing something wrong?
has this worked for anybody so far?
Sorry it seems that there’s a new fix, re-uploading, please don’t download yet, will say “New download” when done uploading!
Still the phone does not work, so what was the fix?
Does not recognise sim card so no calls
Yeah I got the same problem with my sim card, and the mobile data is not working. 🙁
Don’t flash this yet they have tone of trouble they having. Most people using twp recovery has much successful flashing this. read on xda s2 forum
is this fix already? i want to try it
Bootloop here too.
I have successfully downloaded the upgrade, flashed it and all. The only thing not working in my data service………………. Need Help
did you try flashing the radio?
Whats the radio?
Just tried this official j-bean but its to unstable..im using teamwin recovery n i got bootlooped on first try but did another restart n went through but when i was logging in to gmail in the beggining it just restarted and got bootlooped for some odd reason..definitley not stabl…wasnt go to play aroung with it so just went back to slimbean for now but also got a backup of pacman rom too which is ight…but if someone wants a official jellbean look i recommend embryo 6-8 rom which is totally based off the s3 n it has the ink affect…not bad at all…
so many errors: com.android.process.acore has stopped, com.android.phone has stopped… and is there a contact app?
or phone app…
and camera doesn’t work
I got it working with TWRP but it took a while. Seems that everything is working. I downloaded the rom at the top of this page, the debloated one, and flashed with TWRP.
I need to use WIFI Hotspot Tethering, does anyone know if this ROM will prevent me from tethering? Thanks
Well I just tryed to give another shot n I succefully installed it…what I had to do was reinstall it rwice factory reset,wipe system,wipe cache,wipe dalik n install rom…the first time I installed it I got a bunch of forclosing from like every system app,so I did the same process from installing it n It worked..u do get bootlooped on the 4g logo both times but just reset it n it will go through…thats all n theres a download link for the ink effect n tethering on the xda just flashed that n got an error but just dont mind that clear cache n davlik n fix permissions n restarted it n it was all good…but for the tethering after u flash that it says were the download link is u got to erase one the system files away,im about do it now I forget which one.. bout to check now..
Does anybody know of any multiwindow link that can be flashed with ths???? Also a good kernel that I can use with this also???
Has anyone got a fix for the phone not working, also, the camera doesn’t work tool.
Why not just post the Official Rom UNTOUCHED, fact is, the official rom’s gallery app is better, and all the official google tool apps ie calculator etc are all better than what devs go and replace it with or dont include at all. It doesn’t make any sense.
If it wasnt for the fact that I can’t restore my backup apps + data to the unrooted official JB, I wouldn’t even bother these sideshow ROMS.
What’s the best (overall) ROM for T-989 as of now?
I think Darkside Evolution 3 v8 is the best. At least it’s my favorite and has the most functionality.
I would love to see a Darkside ROM built off 4.1.2. Ha, the Darkside ROM has inspired me to start
Learning how to make custom ROMs.
still no working… I just tried they ROM and the system crash, there’s no baseband (Baseband Unknown), there is not contact or phone apps (to dial)
after i insatlled35 T-Mobile Galaxy S2 Official Jelly Bean Firmware with Root and CWM Flashable! [Fixed mi galaxy won’t turn on help please!!!
Max, help us out, please!
As you can see here on the comments there are problems with this ROM; either causes boot problems or features not working properly.
Please direct us to a T-Mobile Galaxy S2 Official Jelly Bean Firmware with Root and CWM Flashable…that actually works.
Thanks.
The official one
