Didn't flashed yet, but if it has eg dipper fingerprint you can also try to use the same fingerprint with 'hide props' as it often fixes it too instead of changing (also it's advised to wipe data of playstore before rebooting)CTS profile failed. Even if I didn't install magisk.
When magisk installed, I already turn on the magisk hide, but still failed
I think changing device fingerprint will fix this. I'll do that later
Edit : I try to change the device fingerprint, but still didn't work
I am not on this rom, but previous posts (e. g. #31-33) indicate that ota might cause problems. I would follow the steps described in the very beginning for dirty flashing. Good luck and merry christmas.
I would be extremely careful about that, because you're essentially getting a paid service for free. Unlimited Photos storage is a perk for specific Pixel users; everyone else's Photos counts towards their Google Drive quota. Spoofing your device signature to mimic a Pixel means that you're receiving a benefit only intended for people who buy a Google branded device, which for all intents and purposes is stealing.
