SMG925F possible solution for serial number and dm verity

[maxdanapoli]

after repairing IMEI and work everything went ok after one day the phone's owner brought him back with me imei corrupt and told me that when he was in his hands he began to take root and other operations without really knowing what was doing.
I fortunately had a safety backup, and then I restored the old imei everything went ok but I noticed that imei is back as the original but the namber serial has remained unchanged since the first certificate that I had then repaired now the phone even if I do DRK FIX octopus and I said ok Not need to Fix actually dM verity is corrupted and if you flash a stock firmware the phone is constantly in recovery and then dinuovo root etc. etc.
there is a way to restore the original serial number and repair dm verity ??

Hello.

Unfortunately repair of SN is not supported for SM-G925F at the moment. As You can see from Software log, phone's DRK is correct and there's no need to fix DM-Verity:
