I just bricked my DX50 after the 1.2.3 beta software upgrade. The player has been stuck on the "iBasso Audio" boot up screen for the last 10 mins and it isn't going any where. Any help is much appreciated. I've tried taking out battery and it still stuck at the same screen after rebooting. It won't recognize on the computer either. BTW, I follow all instructions and what a disappointment.
