I have been shown how to use a code in the dialer to access the Testing menu on my Sony Xperia. I believe that checking the settings in Service Tests/Security can reveal whether the phone has been tampered with, but I could do with some help analysing the entries on this screen.

I believe that if a DRM service is intact, for example WIDEVINE OK [ACTIVE] or WIDEVINE [Key OK] [Active] then the the phone probably hasn't had the bootloader unlocked, but what do the other entries mean?

I am trying to find out what each one should say normally and what it might say if the phone has been rooted or flashed with a custom ROM. I have two Sony phones and the entries vary slightly but they include:

Factory reset reason :

Rooting status :

HUK :

PRODID_AID :

OTP_LOCK_CONFIG :

OTP_LOCK_STATUS :

AUTH_ENABLE :

FIDO_KEYS :

Security conf

Apologies if there is already a guide to this somewhere.
