samsung s3 help
could you please link me to a solved thread with this exact problem please

unless you backed up your efs partition . you cant revert to an older modem . my advice for now is stay with mg4 and back up efs . apparently for as of right now if you change your modem you will most likely lose your imei

[Q] Anyway to know what your stock rom was?

Hi,
I am a noob to XDA and this is my first post, please dont be mean!! I recently bought a galaxy s2 unlocked version from amazon.com and when i received it i flashed in the new leaked jellybean rom:
Android version: 4.1.2
Baseband version: I9100XXLS6
Kernel version: 3.0.21-462349
[email protected] #3
SMP PREEMPT
Build number: JZO54K.I9100XXLSJ
After flashing this new rom my IMEI number had been reset and i am currently getting no network service. The samsung SRS tool is not picking up my phone for some unknown reason to let me reset the IMEI number. Before flashing the new rom i did not take stock of what the original rom was!! Is there anyway to know what the stock rom was before flashing?
Please help!!!!
Well if it was the factory unlocked version, my guess is you had stock unbranded gingerbread.
unbranded

When you say, your IMEI number has been reset, I think, the efs folder got corrupted. its where the phone data like IMEI number is stored.
And if you want to flash stock kernel, you can visit this site, but I'm not sure how you can retrieve this efs folder data.

Your IMEI is also printed on the sticker beneath your phones' battery.
Your probably seeing the sim lock bug and getting confused. if you flash the leaked JB rom your sim lock will be enabled so you will need to use a unlock app.
Use search, we have plenty of topics that cover this since JB leak.
and then some.....

yea i know it is but the imei number behind the battery and the one i am seeing when i dial *#06# are different. i am seeing alot of 9999's and 000's in it..when i googled it i saw it was some sort of manufacturer's default imei or something. i flashed in an unbranded uk rom xwlp7 but when i try to root it using cf-root it is not working now!!!
