This is combinatopn of the last few posts I made about what looks like exactly the same player as you.
Hope it helps.
I looked for my player on this site where all the images are posted, and found the same one (all be it a different colour). This led me to http://www.mympxplayer.org/glacier-r...evc-df621.html
This download includes loads of firmware (operating system software versions) for glacier type mp4's and instructions on how to reboot the player if it is locked up.
Try them all until you get ones that load ok then make sure you get the one out of these that starts the player into the correct start up screen!
PS Although the computer may not recognise it the upgrade tool probably will and say that the mp4 is in boot up state or something similar. (Prob no need to do the chip shorting bit unless you have no luck.) My player was a chinese 8gb (will prob only format to 2gb if it's the same Glacier type as mine).
I thought I would just mention though that I had to flash my memory to get the player going again (out of a perpetual hour glass state which turned to white screen with wrong flashes) with fimware (mine was a Glacier 8gb type) and one of the flashes that seem to load ok allowed the player to play audios and not video. I tried a different one that also loaded and allowed me to boot to menus and this one played both, hurray. (This was the one that gave me the same welcome message on boot up as it originally had!)
I then set about using an amv converter recomended from this site and experimented with all sizes and frame rates and video settings. Mine would only play frame rates of 10 (12 and 15 would cause errors independent of resolution or picture dimensions!)
