No Signal after FW

[hopper28]

Hi

Bought a new Amiko Combo and flashed my backup with my channel file which I used on other combo's and works fine.
On this batch on Astra 28.2 it says no signal when I check the sat finder.

I had to install a FW from Lavatronic ? to get the 28.2 to show a signal.
Can someone explan why only the Lavatronic FW will work.

My problem is I use the HTTP section also and this FW hides this address with ******** .
I would like to use the older FW with my channel list.

Thanks
