I really need help (IMEI)

victorbeta123 · Apr 29, 2012

Hi guys, first thing i need to tell you its about my english, i speak really bad. But please, try to understand me hehehe

I was updating my rom for Galaxy S I9000B, and I forgot to backup my efs folder.. So, I lost my imei.. I was trying to rename nv_data.bak and nv_data.bak.md5 to nv_data.bin and nv_data.bin.md5, but i was looking the date and its the same date (the date same date that i updated my Galaxy), so nothing happens.. my nv_data.bak and nv_data.bak.md5 are corrupted too :/

Im from Brazil, and sorry for my really bad english.. But please, someone can help me?

really thats kinda weird because i flashed 2 roms without having any problems about losing my imei number.
Or maybe i did but i didn't know!

do a search on imei, but i think some people have had their imei restored after flashing stock rom. dont forget to backup efs afterwards, you may have a backup already as some apps back it up (search for efs)

If you don't have back up the solution is to flash a stock rom through odin. This should restore everything. I think you can also flash darky resurrection rom but not 100% on that.

How to back up the IMEI http://xdaforums.com/showthread.php?t=859914

Flashing back to Stock ROM or Darky's 10.2 should restore your IMEI

IWillExplain · Apr 30, 2012

and have you made a backup of the /efs/ partition after you have lost the imei, there might have been the correct file backed up - now it is a mess probably

so here is the simple guide how to revert the imei [GUIDE] Recover your IMEI in 9 steps.
i think you were missing chown 1001:radio /efs/nv_data.bin

and here gereat tool to backup /efs/ partition
[TOOL] Updated! 13/04/12 - EFS Pro v1.4.7 - Advanced '/efs' Backup and Restore!

pick backup to tar and location pc - worked for me, sometimes app likes to crah but it works. jut check the tar file if all files are there after proces

good luck

ive already flashed a stock rom, and nothing happens :/ ive tried too to flash with darkys and nothing.. Ive tried this guide: http://xdaforums.com/showthread.php?t=859914 and nothing :/ the problem is that the files nv_data.bak and nv_data.bak.md5 are already corrupted files..

IWillExplain · Apr 30, 2012

be sure to chown when you are # (superuser) after renaming backup nv_data.bin
you might try it when phone in airplane mode.

your imei is most probably in the backup file

just those dumbasses from xda or darky do not know jack about phones and android how is that ll working. flashing rom will not fix your imei

I've already tried to flash darkys or stocks roms, but nothing happens about the IMEI. I think the problem is that the files nv_data.bak and nv_data.bak.md5 are already corrupted files too so i cant restore my Imei and all the times that i try to flash a stock rom i think the files that my SGS restores are the corrupted files: nv_data.bak / nv_data.bak.md5 / nv_data.bin / nv_data.bin.md5

i really dont know what i have to do but i think that the question is not about to recover my imei. i think the question is about restore my imei, but i really dont know what i have to do, i've tried all..

i did this but my imei continuous the same, fake one.. :/

This also happened to me. After trying literaly every method of restoring it i had to send it for repairs. Cost me £50 as my warrant had expired. I had to go to some local repair shop.

Flashing a stock ROM will restore a IMEI if the IMEI has not already been corrupted.
I can say this with 100% confidence as I have been in a similar situation. However I did not play with the nv_data.bin file before flashing a stock ROM.

To the OP.

Do a search of the I9000 (SGS) threads for a post about restoring IMEI to nv_data.bin I am sure that a XDA user has posted that they can restore the IMEI number. This may be the only option before returning the handset to Manafacturer for service

I had this problem. Did you install the "sgs unlock"? This is what caused mine to show a bad imei number. I had to take it back to manufacturer and play dumb!
