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
