you have to back up the un-corrupted EFS folder that have your IMEI in it.
there are many software and apps that claim to back up those file
you can just search "how to back up efs folder" there should be plenty of solutions and guild.

EFS Backup manual or automatic?

Hi every1
I see a lot of ppl on the QA complain about losing their imei number due to bad flashing and other circumstances.
I dont wanna risk screwing up my phone flashing roms so I was wondering what is the least hassle/best way to backup the efs folder?
Can u just use root explorer and copy the whole folder to extsdcard and then put the backup on the pc for future use
OR
What are the best apps for making backups and are they 100% guaranteed to make a working backup and restore with no problems?
Back up as many ways as you can, copy it to pc, use k-pack tool from the market, and copy those from your sd to pc as well, can't be too safe!
Just to update u guys pro efs will backup your efs folder to your pc no problem I recommend using this before flashing too much

Not 100% on the whole contents of the efs folder but its very important as it contains your imei number which is like a mac address its unique to your phone to identify it on a network always worth keeping a backup incase sonething happens to it

EFS is one of the partitions in the root directory which stores some of the most important data such as IMEI number, phone number etc, things which are unique to your device and will make your phone a paperweight (no network connection) if you mess with it..
Take a backup of this folder in case you face any problems..
