I will get shot down for this, but use this app: http://forum.xda-developers.com/showthread.php?t=1846451
As person above said, it has been answered many times, so use the search function!
Next time you ask a question with no obvious attempt at searching, you won't get help from me.
I had the same problem with the leaked version..i was unable to unlock it directly with galax s sim unlock so i had to restore for Gingerbread root unlock it and then do a backup of efs folder..save it anywhere on your sd card..then flash it..and should be unlocked and if the problem continues restore your backup from efs..and your done

[Q] [SOLVED] Phone locked after JB

Hi,
As I'm new to the area, sorry if I'm posting in the wrong place.
I bought a SII from UK (T-Mobile unlocked) and have been using it in Turkey. Yesterday, as JB wasn't available for T-Mobile UK yet, I downloaded 4.1.2 for Vodafone UK. After installing it, my device began asking network unlock PIN. (I should have downloaded an unbranded ROM, I learned it later.)
I rooted the phone for the first time and tried to unlock it with Galaxy Sim Unlock, but no good. I installed back the 4.0.4 for T-Mobile, but the problem continues.
Now I'm stuck with the phone. Any help, direction, lead to relevant forums would be appreciated. (The ones I searched and read was above my knowledge.)
Here is the screenshot showing the details of the phone.
What can I do without losing the IMEI, etc. information?
Thanks,

with basic knowledge you can't do much...
btw - did you try all unlocking apps from market??
No, just Galaxy Sim Unlock. All the time, I was reading about similar problems and when I saw about the EFS backup requirement, I stopped trying. And looked for more experienced support, here. I didn't want to mess up IMEI as it would cause lots of trouble.
Sure, it takes time to learn but if it'a phone which serves every communication, time urges. So, will keep on reading and find something.
By the way, as going back to ICS didn't help, I thought it would be better to be on JB if I could unlock the phone. Now I have this on my phone (again unrooted):
Baseband version: I9100XXLS8
Kernel version: 3.0.31-889555
[email protected]#3
...
Build Number
JZ054K.I9100XWLSJ
When I was trying to find a way to root, I saw different kernels but I couldn't understand the exact one I needed. From what I read here: "http://forum.xda-developers.com/showthread.php?t=1103399", I have to use a kernel with LSJ. Is it true?

You flashed a branded ROM on an unbranded phone.

i went through the same ordeal! download galaxsim unlock from xda! it worked for me after trying a whole buch of other ones including galaxsim unlock 1.43. good luck!
I'm sure it was a stupid thing to do but give to the long time waiting for JB and getting another ICS. But the phone wasn't unbranded totally, I hated that T-mobile animation on every boot.
Just one thing, as I asked above, can you suggest a kernel to root. I gave the information above and I was confused with the many options to choose among. I'm not sure which one is for me.
Re: [Q] Phone locked after JB
Flash unbranded jb.
If it's still blocked get galaxysim unlock, it's free here at xda.

Solved-thanks.
I solved the problem with the method vanisleryan suggested. I installed unbranded jb as you said. Thanks everyone.
Alright then, you can add [SOLVED] to the topic to help other users with the same issue.

You should call the service provider (sprint) and ask for unlock code, other methods aren't guaranteed and may corrupt your efs partition, or you can give it to a technician, maybe he can unlock it using OctopusBox machine (if he have it).
