( by the way what is the difference between them), are not exactly the ones that came with the device. I could not make a backup of it, and between tries I was "forced to put another firmware in order to unbrick the device. I tried all the firmware available, (OHC, WASSER, Finless), but none of them could make playing video fine through kodi supporting also.of DTS and AC3 . With original ROM I did not encounter any issue.
Thank You very much.
