Downgrade via FFB

Post by ML62 »

Hi,

I have a UE40B7000WPXXN with firmware 2010/06/20-003002.

If I'm right, to run run SamyGo applis, I have to downgrade firmware via FFB procedure. So I have changed the 3 switches ( Wiselink, Watchdog, Rs232 ) and downloaded T-CHU7DEUC firmwares (version 3000 and 2009 ), connect the usb with firmware, start FFB ... and in both cases, after a wait message, a warning is display "wrong firmware version .... do you want to brick your tv" .... after a couple of seconds, the tv reboot ....

What's wrong ? Could you help ?

Cheers,

Marc

will check it now...

OK, it is clear. Your TV is CI+ and has firmware T-CHUCIPDEUC on board. This is visible on your model:

And in logs of FFB...

You can`t use FFB for downgrading. Sorry.
