[Q] My Samsung Galaxy SII LTE SGH-I727R needs help - General Questions and Answers

Hi All,
I'm new for this forum and need some help if I could get someone in this forum know how to fix my problem.
Here is the story:
I bought an used SII SGH-I727R few months ago and it's unlocked. I have a plan under Mobilicity (Canada). everything was fine until last week when I decided to upgrade my android to Jelly Bean (and I did) and now I the phone doesn't work with my SIM card anymore (I borrowed my friend's SIM card under Telus to plug it in and it works!). Something telling me that I screwed my radio freq (band) settings.
Here is the old spec:
Android: 4.0.4
Baseband: T989DTLLE4
Kernel: 3.0.8
Build: IMM76D.UCLF6
PDA: I727UCLF6
CSC:I727ATTLF6
IC:649E-SGHI727
and here is the new spec:
PDA: I727RUXUMA7
Phone: I727RUXUMA7
H/W: Rev 1.0
RF call date: 2012.06.10
CSC: I727ROYAMA7
I did try a lot of radio zip file in this forum and use cwm to install them but none works, If someone here has experience and know exactly what I need to do to make my phone work with Mobilicity again, I would really appreciate or even bring back to the old version/setup will make me happy too.
Thanks in advance

[Q] Questions about my GS2 LTE version

Hello everybody,
I'm French and totally new in this forum.
Just got a Galaxy S2 LTE from my dad who brought it back from a biz trip in Germany here's what I found when I checked the phone's version:
Baseband: I9210XXKI5
Kernel: 2.6.35.11-I9210XXKI5-CL616063 [email protected] #2
Build number: GT-I9210-eng 2.3.5 GINGERBREAD 0XXKI5 test-keys
Anyone can tell me something about it? I know that the phone is rooted because Root Check Basic told me so.
As I'm living in France, will it be a problem if I try to upgrade to ICS?
Thanks,
Max
Well your phone is definitely not the Skyrocket, but it definitely has the same chip set. I wouldn't advice rooting with any if the skyrocket methods until you know it's safe.
Sent from my GT-N7000 using xda premium
Indeed, the phone isn't the skyrocket but no for the GS II LTE
Does anyone know where I can find the stock firmware so I can unroot the phone?

[Q] Help needed to root and update galaxy nexus i9250 to jellybean IMM76K.I9250XWLD2

Hi all,
I am a new user to Samsung Galaxy Nexus. I wished to root my device but however i am not too sure with the model i am having.
Model number : galaxy nexus
Android version : 4.0.4
Baseband version : I9250XXLA2
Kernal version : 3.0.8-gda625b
[email protected] #1
SMP PREEMPT Fri Apr 13 11:35:09 PDT 2012
Build number : IMM76K.I9250XWLD2
This is my phone's version and i think it is a GSM model. Because I am living in Malaysia and I am currently on GSM. But when i search online it shows that IMM76K is verizon model. So i am a little puzzled.
Hope anyone out there can help me. I would like to root it and update it to Jelly Bean.
Many Thanks
I am in the same position. I am attempting to install JB on a newly purchased Galaxy Nexus using the toolkit and have the IMM76K.I9250XWLD2 build number which shows in the toolkit as CDMA/Verizon but the phone is a GSM model... I am really unsure what my next move should be... Any help would be greatly appreciated.

F**king **** why no ones replies to this question?
please guys! help out THANKS!
Same here... Not sure if anything changed when I received the OTA update to 4.0.4 a couple of weeks ago... Doesnt make sense, I got this as an unlocked GSM phone and works fine here in Costa Rica. why is it a verizon now!!???
Unlock the bootloader
Use the toolkit to flash it back to IMM76I, google stock rom (all data will be wiped, please backup everything!)
Try see if you can get the OTA, its gonna be random and take sometime, you might want to try installing the OTA in zip form via CWM.

Y7562 Smart Phone

Hello,
Could someone be so kind and point me in the right direction to this Chinese Galaxy knock off, My friend purchase it and im trying to get it rooted and install a custom Rom. It has the stock Rom but for the life of me we try att,tmobile,net10 sims with the correct APN and still says no service, So I would like to root it and try a different rom to see if that works,
Any help would be great. And yes I did a search and that model doesn't show up.
The corrent rom on it is:4.0
Baseband: DM_BASE_12A_W12.43|sc6820_modem|11-01-12
Kernel: 2.6.35.7
Software: 6820_4.0_c910_YP_v13
Hardware Ver: 1.1.0
Duo Sim
Thanks in advance.
This has nothing to do with the Galaxy S Duos (GT-S7562), unfortunately. Incompatibilities relate mostly to hardware differences.
Cheers,
C.

[Q] StraightTalk Needs Android Upgrade.. Help.. PLEASE

My boyfriend has a samsung galaxy s3. It was originally a sprint phone, which is now flashed over to be used on straight talk. HE got it flashed a couple years ago I believe... so most of the settings and stuff are completely outdated.
This is what is in the ABOUT PHONE section:
The Peoples ROM GS316
BUILD NUMBER: JZO54K.L710VPBMD4
ANDROID VERSION: 4.1.2
MODEL NUMBER: SPH-L710
BASEBAND VERSION: L710VPUCMK3
KERNEL VERSION: 3.0.69-KT747-g256c7b3
[email protected]#1
SMP PREEMPT Fri May 3
21:14:27 MST 2013
HARDWARE VERSION: L710.14
so... I was wondering how I can update his Android to something newer.
I am kinda a beginner when it comes to ROMS and KERNELS and stuff...
Do I have to Flash something? What do I use? WHats the best ROM to use? Sorry, but if someone can maybe explain it step by step or maybe send me to the right place where I can read the steps on how to do all this...
How can i do all this, hopefully without erasing anything on his phone? or if that is impossible... then how do I do it?
Please, any help and info is greatly appreciated.

I am fine with that, but i will need to know every step to get my device to 4.1.2. Thank you very much!
