hi,
I broke my mp4 player

I flashed it with this:
RK2608A C204 NexxTech Version: 00.00.0008
http://www.mympxplayer.org/firmware-...204-df724.html
before that I had version 00.00.007
now its kinda working which means that only one key does what is supposed to be doing (navigate left) but all the other ones aren't (when BackLight is dimmed and I press them it changes but they don't work when I try to navigate in menu) because of that I cant put it onto FW update mode

is there a chance of fixing this?
unfortunately I haven't got the original FW so it can be difficult to bring it to life...
