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

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

o seu Inglês não é tão ruim

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!
