Hi,
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!
I am willing to help as I am so chuffed with getting mine going again after weeks trawling the net, that I want to spread the word.
Cheers
Tony
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).
