Hi @fubuntu,

@fubuntu said in Install with ubports installer resulted in having a debug kernel:

But I also read the fairphone support page, and according to it, flashing with fastboot (downgrading included) should be no issue.

In my opinion, the “anti-rollback function” is an additional security feature to prevent customers from installing older Android versions on their device that are no longer supplied with further security updates.
This would give customers a false sense of security as they would consider their device safe with a locked bootloader.

For developers or customers who use their device as AOSP (Android Open Source Project), however, there is still the option of a rollback or installing a different operating system and using it with an open bootloader at their own risk.

See also source.android: lock and unlock the bootloader.

But I could also misunderstand, nobody is omniscient. 🤔 😀
