[eduzeta]

hi,
I have a box tv android: BOX VISIONIC INTERNET TV HD I wan't update with file.zip but instalation don't work and now when i reboot my device i have only a picture android and system don't run. I can go on cwm recovery with reset button inside the device. But i can only choose reboot system cause i can't go down with vol/+ or vol/- or key up or down. I try many files.zip on my sd card but this is the message i have :
