MyMPx.org - need firmware anyka ak3631

Hello to all,
I have bought a mp4 touch screen player with camera and 4gb flash space from ebay. I thought the price of 60€ was ok for this player...after much frozen menus... now the player freeze on boot...i can see the "please wait...Welcome" picture on start but the player dont start.
I have tryed to contact the ebay seller: digita.world but he dont sell anything now and dont answer to my warranty-pm. So i have opened the player to look for the chip and to find new firmware. In it i found a chip with the inscription: "anyka AK3631LQ14402 FS05A8"
please can you help me to recover it?
if you need other information about player pls ask
