nice find man24
I simply do not have the time to try this, but it should work in theory. Will try next or when i next get a chance. If anyone tries before please report back
looks like we are out of luck, it's not even worth a try, check out the replies from Vitalik at the end and a user who said this:
"GTmedia, not have same dvb decoder of k5, and for what I know there are no open sources/driver for gtmedia to port something (TV side). Also, you have misunderstood about mars firmware... its not compatible for gtcombo, mars firmware are only for gtmedia trash decoders with no android, like v8 UHD, v9prime, etc. Mars firmware is a buggy firmware, its slow and often it freezes. About gtcombo, it's another piece of trash, in every firmware updates, the problems increase instead to fix something. In the last firmware, with some oscam config. it freeze... in most channels, there are desync audio-video or video frame jumping random."
"For GTmedia Combo there are no sources of dvb drivers in the public domain, I have this set-top box, as soon as the sources appear, I will compile the firmware for it."
