Hello,
firstly: I really appreciate the project and all the work that has gone into it, as well as the helpful community.
I installed the latest build of DivestOS 18.1 on my FP3 today following the instructions on the DivestOS- website after having run LineageOS for microg for almost two years. As I`m not very experienced in installing custom ROMs I stuck with 18.1 as opposed to the still untested 19.1.
During installation I encountered some (hopefully minor) problems:
Initially, updating fastboot using fastboot update divested-18.1-20220711-dos-FP3-fastboot.zip did not work stating fastboot: error: boot partition is smaller than boot image. I couldn’t find helpful advice on the internet, so I went ahead and sideloaded copy-partitions and DivestOS using the already-in-place LineageOS-Recovery (as there was no specific DivestOS Recovery available for FP3). As (probably) expected, the update package signature couldn`t be verified.
After sideloading, I went back to bootloader and followed the instructions about flashing the custom AVB-keys.
DivestOS now boots without a problem an is working flawlessly so far.
Now I`m wondering if the two problems I encountered (not being able to update fastboot; not being able to verify the build signature probably due to using the LOS-Recovery) might cause any problems when trying to re-lock the bootloader. I really want to avoid bricking the device, yet being able to re-lock was one of the main reasons to switch ROMs.
Any advice is appreciated. If you need more detailed info or logs I can provide those, but please tell me how to obtain them as this is the first Custom ROM I installed by myself.
