V8X downdrage Mars by USB

Post by guitar.bird »

Hi all,
I would like to Downgrade Mars to standar version.
I tried to do it by the refresh tool but my pc does not reconise the rs232.
Is it possible to enable downgrade by USB please on the next version of Mars ?

Thanks teams!!

they are different firmwares, I don't know to what extent this would be possible.

although it is true that from original firmware we can install Mars without problems


maybe in the future...

Use the Power key and the mars file renamed to update.bin since version 4898

Tell me is that to go back to the original rooms, ie before version Mars as Mars has killed a lot of satback channels ,all.the HD will not encode, the auto biss will not store as auto, I have also noticed when you do a blank scan the Mars room keeps doubling up the channel lists again and again. It only scans as all radio channels on satellite and there is no way apart from using the editor externally to port channels. On the sd ones will work, no HD flags in editor so biss does not encode. Etc etc very much beta rom that should have not had a update flag every time you turned it as it has too many bugs.

Downgrade without rs232 ???
