You could follow this guide from w2comp
You can upgrade / restore firmware for yourself, here we will teach you how to do, first of all, you can download the firmware first.
1. Extract the zip / rar file and put "install.img" file to USB drive* to root (don't put inside any folder).
2. Then plug the USB drive to player.
3. And on the buttom of the player you can find a "Restore" / "Upgrade" button, press it and do NOT release then power on the player.
4. After 10-20s, you can release the "Restore" button, then it will auto to reflash the firmware again. It should take around 3-5 mins.
5. Finally it will reboot, now should be ok.
* We recommend a USB flash drive which is 1-8Gb with FAT / FAT32 format.
