Hi to all.
I bought an used 7025 and a dtt board for it.
Which are the steps to install the dtt?
I haven't any guide, so i tried in this mode but it didn't work:
1- remove 1 dvb-s
2- install the dvb-t
3- swich on the dream
After about 2 minute of booting, it start a looping of blank display and booting logo.

Who can help me, please?
Thanks
