Xtrend ET6000

This weekend I had a problem with the energy supply (the energy power supplier cut the energy due to bad weather conditions) and my receiver (ET6000) was not powered for a while.

When the energy came the receiver was not booting, only appears the boot screen (and the leds red and green are always on). I can a access the receiver with telnet and the errors are (Crash Log in attachment) :

[fb] /dev/fb0 No such file or directory
<    343.831256> [fb] framebuffer not available
<    343.831317> FATAL: [gFBDC] no framebuffer available


I try install the bootloader and a new firmware again and again and the receiver accepts them but is always having the enigma2 crash.

What can I do?

Thanks in advance!
