I've a Mut@nt HD51, that I've not used for a while. Over the decoder run OpenATV 7.1, and there are the four slots with differents backups. Restarting it after some months, it seems bricked, stopping the boot sequence when showing the full screen logo of OpenATV. I've tried to flash a new image, but it seems to not boot, while ssh access is probably working, but don't recognize root password.
What should I try? I will buy a new usb key, but probably that's not the problem...
thx
