sorry if my english is not understandable
I rephrase the question
I took this phone recently and would like ROOT rights, but I have seen that with this version of rom it is incompatible
I'd like to downgrade.
I thought there was a way to perform a full backup of nvram, in case of ROM downgrade would I lose all functions including the fingerprint?
If you want to restore the IMEI, you can do it, but the fingerprint function doesn't
Will the function be in an NVRAM memory location? would it be enough to know if the scatter.tx file of this rom contains the call to memory addresses, or is it a system app?
This was my question
if anyone can help me even to clarify my doubts
