I was thinking about phones and there bootloader failsafes... and so I was wondering if it could be a bit of both (software+hardware) and intended (so to explain the difference between the 2 messages). My other theory being, a fuse is triggered...
I'm convinced there is a part of software (be it system or chip related). It's only a guess considering, there shouldn't be any difference like that because for my part I updated the firmware using a PUP and still this message stayed the same.
Same as all of us. It has to mean something. Like some kind of advanced demo mode...
