I tried already another USB Stick and format it as FAT32 MBR. 


Thanks already for your time and help! Any advice is welcome, I bought the player just 2 weeks ago.

If your player is showing a panel CPU error, then you'll need to either have it serviced or consider returning it if you're within the return period of your retailer. It's not something I'd ignore as it won't get better on its own.

I have found some threads that there is a problem with the usage of Rekordbox for playing tracks? Is there any advice?

What I want try:

- Flashing the panel with an older Firmware but I dont find any older version.

- Flashing only the "MAIN" because, this fixed anyhow the problem last time. Maybe it was an coincidence but it has only flashed the MAIN and this worked for me. Does everyone know how to get to this flash mode?
