Thanks a lot for the info Th3_uN1Qu3!
I've edited my original psot above and will post here the error and device id windows shows when the device is in firmware upgrade mode. Maybe someone can shine al ight on it.
The device shows up as "Unknown USB" device in windows with the following info:
VID_071B&PID_3202\5&348A32C4&0&6
Windows complains about not being able to find a "required" section in the .inf file, which i checked with my device id above, but it seems to match up fine, any ideas on how to fix that?
What can i do to benefit others on the forum, since my firmware is not dead and works fine, it plays all of my mp3's (vbr, 320kbit, etc).
I'm now doing a full low level format with the mp3 player tool to make sure i dont have a hacked device, its going slow, 39% written so far. I'm trying to include an image below with the usb error windows gives me when loading one of the rockchip usb drivers. Thanks for the help and info!
