Pinebook Pro won't post after hard reset

>I waited for a while and turned it off by holding the power button for 15 seconds.
??? I've always found that ~7 seconds is enough to force it off
Just today, yet again, I had to do "extra long press" ,, appeared dead, only chg led
This is almost 10 times by now (my fault, messing with various uboots)
So, it costs you little
Make sure that a bootable SD is in socket
If there is a bad uboot somewhere, disable it, get it gone
Don't let up pwr button too soon, if anything give a few extra seconds,,, 20+s
If you hold it only 18s, won't work,,, I know documentation says 15, that is wrong
Then, a normal start press
