Backup & Restore EFS on your OnePlus 3[Root Needed]
To Backup:
1) Enable USB Debugging Settings -> Developer Options -> USB Debugging.
If Developer Options not found, go to Settings -> About Phone and tap the build number rapidly 6-7 times till a toast comes up saying 'You're now a developer' . You will now see 'Developer Options' above About Phone in settings.
2) Download the attachment, extract it to a folder, connect your phone to PC through ADB, double click on 'BACKUP EFS.bat'. When it says 'Press any key...' just press any key on your keyboard! You'll see 'modemst1.bin' & 'modemst2.bin' files in the same folder where you extracted the ZIP, make more copies and backup of it! That's your EFS!
DONE!
Backup tested on OnePlus 3 OxygenOS version 3.1.2
To Restore:
1) Connect your phone in fastboot mode to PC, place your 'modemst1.bin' & 'modemst2.bin' in the extracted folder, double click on RESTORE EFS.bat'.
DONE!
I could not find any tool so far and apps from Play store fail to create a backup for OnePlus 3. So I have re-used the tool created by @Paresh Kalinani for OnePlus One and modified it to extract for OnePlus 3.
