Hi.
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 or .bin files) for glacier type mp4's and instructions on how to reboot the player if it is locked up.
Try them all with your upgrade utilities that came with the mp4, 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).
Some 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!)
Good Luck
Tony
