MyMPx.org - Firmware AK1025 board: Golzi G-18A v0.3 display: LDF TT-1837

Looking for working firmware, because my player crashed and I do not have a backup.

It is an ipod nano clone, which I purchased as 8GB. But in fact it has only 1GB Flash on board.

flash: Hynix HY27UT088G2M (1GB)

found a firmware, which is almost working, but grants no access to the flash in player mode (err: "disk error"). GUI, Games and FM is working.
Access to flash in mass storage mode is fine.

I also found two firmware files on s1fw.com, but the download links seem to be broken :(
