I'm sorry for my english. I'll try to explain my trouble here:
I've bought mk 808 on geekbuing… for 4-5 days it works good but yesterday, after a crash of playstore, i've turned off the key tv and after that the key has stopped in the booting screen ( when appear the "android" logo).
how can I fix it?

this is my situation:
on top-sx there is the psu
then there is my configuration, whitout micro-sd or hdd
then the screen when mk stops,
and then there is the logo of reset mode...after that ( 1 minute) the system reboots and stops.
I tried to use moborobo but I can't put mk in debug mode because it stops on screen of boot!
Tnx to all
