Thia doesn’t help me, it’s stuck on the loop dueing startup, so i can’t access Settings
I just discovered how to access the system utilities and got through that stuck loop. Somewhere in all these comments someone sugested to wait for manufacturers logo to disappear and then do a force stop 3 times which didn't work because the 3 to 5 second lag time to shut down was too long and the restore would kick in before shutting off.
Then it was sugested to take out the battery and unplug the power right after the manufacture logo came off. This is a good way to shut down immediately but it still didn't kick in the diagnostic utility, it went right back to restore loop.
Well guess what, you don't need to wait for manufacturers logo to go away. As soon as you hit the power button, start tapping the F2 key repeatedly until the system utility window appears. I havent explored all the options yet but there is a restore default button and there is an option no1 boot override setting. I haven't tried yet.
