For some unknown reason, hboot occasionally refuses to find a PC10IMG on the sdcard.
Seeing as fastboot always works, there's no need to really bother trying to work out what the issue is with hboot not always working.

Thats what has been dubbed 'Weird RUU Mode'
You have to run 'fastboot oem boot' when its in that mode to get it to boot, then you have to run misc_version 0.4
Push it and chmod same way as misc_version 0.2 in this guide, but use " -r off " instead of the "-s 1.00.000.0" switch.
Then it should boot normally

try rebooting it, the few times I had touchscreen issues, rebooting it got it to work. Otherwise, if its a g2/dz, use the trackpad?
or you could try fastboot flashing a PC10IMG when its in that weird RUU mode
