Hi, everybody, i'm from Brazil

To make the long short, my Kobo Touch K905C frozen after a wrong update, i:
a) already have a Sd Card Image
b) my Kobo is really froze, i guess - when i try to Power, only one thing happens: the indicator light blinks 3 times: Green, Blue, Green, and nothing more
Now i wanna know:
1) is it in Coma or it's a corpse?
2) what do i do with this sd Card Image, if anything is possible?
Thanks you all
