What I've get to know by investigating is that you player is a Omega V88, distributed by a Chinese company named SourcingMap the link is
here
It wouldn't be hard to get it from USA. Surely they don't manufacture the device, which would be important to get the right firmware.
Concerning PDAs, I do have a rockchip 2.2 device made by some TJD Information Co., model SYM-417, TJD gracefully reject to send the firmware to end users, anyway I know is a walker firmware. so I will start to play a little with it.
If something goes wrong I mainly use a Meizu M3 which is my baby toy as deliver the best sound I've heard in a PDA... iPods included. I am more into the sound dept. than in videos.
You did use ConsumerUpdate to install the firmware really?
thanks in advance,
