I use my tool FrameHunter and no, there is no way to change anything else excepting the background images (at least at the moment).
The images are here.
Hi Danila, I used your tool and built my own image. I followed all your instructions (same frames size, same img size ..).
Everything is ok.
I have 2 questions:
1) You seem to have the same unit than me (MT6505 GF w/ DVB-t MPEG2).
On the main menu of the unit (frame_3.jpeg), you have USB button (between DTV and SD) instead of CDC. How did you do that? Did you have a new build img from Maisun? if yes, can you share?
Between DTV and SD, I have a CDC button (not needed, I don't have CD charger) and my SD button is a SD/USB button but USB can't be selected, even if any SD is inserted.
2) Your font seem different, did you do something special?
