Serp, my manufacturer has recently emailed me with my players original firmware. I tried uploading it to the site but the connection kept timing itself out for some reason, might try again later.
Anyway, it's a 2g nano fake firmware. made for a 1.8"TFT screen, although i'm led to believe it's compatible with some 1.5"s.
I had the same problem as you. What I thought was the right firmware would not get recognised by the update tool.
What I believe was innappropriate firmware would load instantly.
the 20+ firmwares I tried would load onto the player in a matter of seconds.
The original firmware took close to 3minutes! From then, I knew I had the right firmware.
Anyhow, here's a pic of my player

If you (or anyone) for that matter need firmware for the player above or one fairly similar, PM ME.
Mod/admin, I'll try uploading again some time tommorrow. If all fails, i'll send one of you guys the firmware to upload onto the site.
Thanks.
All the best.
