Yes I'll watch the Firmware file with a Hex Editor for any .tag name and then try out if it works on my player if it works I'll back up and install if not I won't even try
By the way my player doesn't have an Hold Switch, it has two power off buttons but now hold(Shutdown by removing power source, Hold PlayPause button is normal shutdown saying Goodbye)
I'd like it more if the Switch would be used as keylock switch and just only use playpause hold to poweroff
Edit:
Also some more info about my player, it also plays Flac I don't know if it's special tough
And if somebody can tell me possible video formats which this rockchip can support but some firmwares haven't got it I'll try those formats
I thought ASF was one of those formats right? because ASF works just fine on my players
So far I tested:
AVI Divx 5.0 - Works
ASF - Works
MP4 - Works
I'm still amazed by this player that it can do so much for the same price in my country you get a Cheap brand MP3(Small no color screen) if you pick 8GB
Tough it makes me worry it will break fast(The price is just unreal)
Edit:
Tested some more so now:
So far I tested:
Video formats:
AVI Divx 5.0 - Works
