So here we are again.
I just got my unbricked Fairphone 5 back yesterday and wanted to give this another shot.
So installed iodeOS 7.3 on the Fairphone yesterday and that worked great.
But i didn’t lock the bootloader, yet.
Instead i just booted into the OS first and made sure both “OEM unlocking” and “USB debugging” are checked before trying anything.
I think i read yesterday something about checking get_unlock_ability in fastboot mode as well before trying anything.
Might be me being a bit paranoid, but i don’t want to mess this up again, especially since this whole support ordeal took quite some time.
I read in this post Booloader relock limbo on Fairphone 5 - #17 by rik
about both needing to lock_critical as well as locking the bootloader, anything else i should be aware of?
Also i am not sure about the security patch level, my settings say i have a vendor security patch level of 5 February 2026 and an Android security update with date 1 February 2026, so should i wait for the next version of iodeOS before locking again?
