Efs - G2 Q&A, Help & Troubleshooting

Is the efs swappable between devices? Say my friend back ups his efs. can i then restore his backup if we both have the vs980?

No, efs is unique to each device.

No need to backup efs if you want to stay on stock.
And no, you must be rooted to backup efs partition

If you did a backup then you should be able to restore that backup using the same method. Eg: If you used an app, that app should be able to restore the efs folder.
The problem with the EFS folder on the latest versions of Android is that it doesn't contain the IMEI, last time I checked. The IMEI is now stored in hidden partitions, which is why when it comes to backing up this important stuff I recommend Wanam's EFS Backup tool from the Play Store. Not only does it back up the EFS folder, but also backs up those hidden partitions as well as the modem..
In this instance however, Lennyz1988 I believe has the right answer.

IMEI=0 after restoring external backup

Hello, a friend had IMEI 0 and restored the efs and persist backup from another device and now he can't restore his IMEI, even after flashing lastest pie stock.
Any ideas?
Congratulations!! Flashing another persist and efs backup is the safest way to loose your IMEI.
If there's no backup of it's own (and I guess there isn't) he won't be able to restore his IMEI.
The /persist partition holds a little binary which is unique for each device. It's impossible to recreate it.
