Debloating a stock OS isn’t recommended since those apps will come back anyway should the system update
really? at every OS update they will be brought back? there is no way to prevent that?
Leaving your bootloader unlocked and rooting your phone as well is detrimental to Android security. Please don’t do that.
my option #2 was to unlock the bootloader only to debloat and to flash privileged apps like fdroid, and then lock it again. Would this still be dangerous?
