Format data using twrp, this will remove encryption from your twrp as well but make sure to save your data somewhere because this will format your internal storage as well.

No, USB connectivity setting reboot the phone on custom rom but not with stock ftf.
The logcat message is wrong as the error reported is not true.
Something is interfering, maybe the root or recovery.

IF you can detect updates through erecovery then it is fine but if it doesnt show any file.
then you have to use 3 button update method to roll back to previous version rom.

Try to flash update.app through erecovery . Via 3 button trigger.

NFC panic

Hello.
Recently i've unlocked bootloader , installed twrp and make a full backup of all in twrp (except for data) , after this i've installed a custom ROM .
After testing i restore enterely the rom with my backup emui 5.0 pra-lx1c55b161 . The procedure went well except for 1 thing NFC panic .
With nfc panic i mean that nfc goes from on to off repeatedly without stopping and I can not do anything to stop it.
I tried resetting several times even by cleaning cache partitions, data and system, but nothing.
Your device has NFC ? Mine doesn't :/

Has anyone tried it? Can we use Orange recovery for the installation?
Been running it for two days and so far it's been absolutely flawless. Orangefox worked just fine. Format data is essential as usual.
Im stuck on bootloop

Im quite interested on flashing the official, but seems still buggy.
Seems like the updates are rolling out quite regularly.
