Hi folks

How to take a backup of the efs partition ? I am not seeing it in twrp partitions list for backup. Any help is highly appreciated.

If you are looking for a quick solution, you can try the app(s) available in play store. Requires root and I believe you are rooted.

Nandroid backup through TWRP will save EFS with other partitions. Or you can try terminal commands through TWRP for backing up the modem files. Don't ask me for commands, I will probably mess up the code !
