honestly, report result of 1 month old system is at least - not possible to recheck, reuse, make anything usefull out of it.
Only thing I can do is generate a new image when you don't want to upgrade.

Normally I would go to ask details to try to fix later, but honesty, what you are saying is that the cubox is unusable - I would throw it into trash as if a platform does that what you describe, it is weeks months of fixing or messed HW in in-reparable state. without any side intentions - what you say is quite inconsistent we other reports and quite much. That kind of state was the hw & sw let me think, mabe Feb, March?

Isn't possible you have short circuit somewhere ? sounds very similar. Otherwise, send ANY kernel log / xbmc, it must be something reported all over the place/time.
will provide the img in few minutes as build finishes.
