I've been using Rockbox just fine for some years, and now, my Gigabeat stops at loading and displays a red/white box with the message "SYSTEM ERROR 00000040"
I've tried to solve it reinstalling Rockbox and the included bootloader. Nothing improved.
I've also installed Gigabeat's original firmware v3.0. Nothing improved.
I've searched everywhere for a solution, and nothing.
I can connect the USB cable to my notebook and have access to the HDD just fine.
Later today I'll make an entire backup and format the Gigabeat's HDD using Toshiba's tool included with Gigabeat Room.
Hope someone can help me out.
