I have tried to install your Musical, Musical J and Fun firmwares but I got a message saying I need to connect device through USB cable.
I have used the software to change to region J and I do not have any issues with DMPX and UltimateX firmwares.
Do you have any ideas?
According to my unit sticker on the side, my region code is AEP, UK.
