There are uboot commands, the syntax is a bit odd,
and documentation is quite hard to find
I know I spent most of a day trying to find useful uboot info, didn't find
The recovery button is known to be flakey
In this situation, I would try to short SPI clock (to ground)
The power flows thru a 10K resistor so it is very small power
A wire with a good alligator clip on one end (grd), soldered to a SHARP pin for the clock leg
U18 is quite close to recovery and reset button, I think the closest chip (it will be labeled)
It may have a dot rather than notch, at #1 pin
OR rkdevelop
with all media removed, a usb male to male, rkdevelop on some linux box or laptop
But I don't know those commands either, it's pretty esoteric
The usb on pbp goes to gadget mode, I think you write a 16M /dev/zero file to SPI
-----
2 or 3 people, perhaps 1.5 years ago had this same problem, for them it also was a bit painful
IIRR one did the short, another did the rkdevlop
you could search the archives
------
and here is info on rkdevelop
