I just tried that for the sake of experimentation - after restoring non patched boot image ofc - and it failed.
Luckily it didn’t prevent me from booting back so there’s that.
A bit disappointing that you had to rely on the OS update feature knowing how unreliable it can be depending on country/carrier/settings-messed-with.
I wonder if there are full build package somewhere to download in the form of a zip, that I could tried to flash on top of mine ?
Yes it was, but doesn’t seem it can be flashed…
