Box type: DM500C
GUI (enigma1/enigma2):enigma2
Firmware version:1.09

I had installed gemini 3.20 and everything working perfectly and updated to 3.30.

Since then I have lost the ability to get any signal.

I tried also official 1.09 but still when I scan for channels the signal stays around 69%. Even if i disconnect the cable from the box, the signal still stays at 69%. So it seems that the box thinks there is no cable connected.

All updates that I did were by putting in /tmp the image file and renaming it to root.cramfs.

I did Factory Reset after every reset.

I unplugged the box, unplugged the cable from the plug but still I get nothing.

Any ideas on what I have to change so that the tuner works again?

Maybe 3.30 wasn't correct and now the box seems to think that it is 500S and not 500C, that's why it doesn't detect the tuner?
Just throwing ideas here trying to figure out what has gone wrong...

One thing I noticed now was that SNR stays between 65-69% with or without cable.

One difference though is if i discconect the cable AGC goes up to 99% while with cable connected it is around 43%.

Reflashed official 1.09 with dreamup via serial but still have same problem.

Any ideas?

I'm supplying also my dmesg:

is there a chance that the tuner got stuck and doesn't switch frequencies?
It has happen on my Pinnacle TV tuner card on PC that's why I'm asking...
