Hi everyone

I have some questions about Samsung SM-A720F

here is Samsung SM-A720F which has frp lock ! (FRP = On)

I know how to solve this problem, but it has another problem that doesn't let the device to become Ok.

First, the "System Status = Custom" in Downloading Mode , which usually flashing device with Official Firmware it should be changed to "Official
it's wired !!! I've tried 10 different Firmwares with correct binary (the phone's binary is 3 and firmware's binary is also 3)

but it doesn't changed to "Official" ( still System Status = custom :| )

note : i also tried combination files on this phone !

Second , after device flashing , it's just rebooted to recovery mode and shows the below error messages :

- E:failed to mount /efs (Invalid argument)
- E:failed to clear BCB message: failed to find /misc partition
- dm-verity verification failed...

As i know flashing the custom recovery on phone and adb commands solved my problem ! but frp lock is on and i can't flash the custom recovery !!!

note : phone not booted after flashing !

Does anyone know how to deal with this ?!
How can i use Octoplus Box to reset frp lock on SM-A720F in Downloading Mode ?

Reset FRP via Download Mode is not supported for this device model at the moment. You can reset FRP in this device via Octoplus Samsung Factory Reset FRP / Reactivation Service using Octoplus Server Credits.
