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?

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://forum.xda-developers.com/showthread.php?t=859914

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

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

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
