Sounds like a different problem to be honest.
Did this happen after you tried to flash the receiver?
If so, can you link to the image you tried?
Have you checked your power supply/connections to make sure it's getting power?
Yes, it's happened during a flash of a backup image, taken on a forum that is flashed many time by many users.
Oh i've checked many time the power supply, after that i take it to the vendor and he replaced it. My error , I think, is that I've switched off the decoder to reboot while the eprom have no image loaded. The display of decoder was black, no signal on tv... bricked . I think , I'll never flash my new os mini combo ...
