Locked fastboot and corrupted e/OS Fairphone6

[9and3]

Small question here @yvmuell , more of a curiosity: as you suggested, I wasn’t able to flash the FPOS into my blocked device fro the bootloader. But reading this (amazing) guide:

@koumilak

The bootloader has a security feature that cryptographically checks that the system image on the phone is authentic (from the original manufacturer, i.e. Fairphone Android OS). Unlocking the bootloader makes it bypass those checks and then the system can boot any valid OS (with which the phone will still work).

I thought this should be enabled because it must have some cryptography signature to bypass the bootloader checks, right? Unless, since I bought it with e/OS from the official store, FPOS wasn’t the original distribution image, hence not recognized by the bootloader..(?)
