Downgrade from Pie to Nougat

[pete80pro]

I already tried to downgrade from Pie to Los 14.1.
But RIL does not work after Installation. So I probably missed something.

I think i need N Firmware first, right?
So how to downgrade correctly?

Thanks in advance!

Depends on the firmware you were prior to flashing pie. You can fastboot flash according to that. Or just get a TWRP flashable stock build of nougat.

Grab the latest nougat from this thread:

The versions that use the aroma installer will make sure that you retain your IMEI by fixing your persist permissions.
