Well, the old SGS2 decided to hard-brick itself. I looked up at it to check the time (I had Desk Clock in the foreground) which said it was ~12:15. I looked at it again a while later and it still said ~12:15 (the time was ~14:30), so I investigated – it was frozen, so I tried rebooting. When I rebooted, it looped the “loop” portion of the boot animation indefinitely, so I attempted it again by holding the power button – after which it remained on the boot pic (separate from the boot animation – the manufacturer/carrier logo). Then I tried a third time by pulling out the battery and now all I get is the notification light. I can’t get even to Recovery or Odin to investigate any fixes, resets, or restores.
