PBP won't boot (no amber or green LED)
>don't update it if you can at all avoid it
I strongly suggest the kernel/uboot update, icon next to time (rock login)
Or mrfixit_update.sh (which is same)
The mrfixit distro is good for another reason than recovery,
it is 64 bit kernel and 32 bit userland, so if you need to run something only armhf.......
--more--
>Pressed power button 60+ seconds (very firmly) multiple times. No response.
After the long (20+s) press, let up, then a regular 1-2s start press,,, a quick tap is not enough
Sometimes it just need a hard power-off (7-8s),, not a hard reset (20s)
So, always, first try a hard power-off, and then if it does not work a hard reset (with good media)
