Hello,
Same issue with my ET6000 after deepstandby....no more boot..just the pinguins...
Tried to flash several images with same result..at the end no more flashing process could start...
Sent it back to the shop...the guy is discussing with X-trend to solve the problem...
i solved the problem by flashing the firmware by renaming unforce to force....
but bootloader flashing is still impossible
2 times turning switch on off to boot (start the box)...
