Guys what should I do... I installed 1.2.8 on my device this evening without any trouble and was listening to music. I unplugged my headphones for about 5 minutes and when I came back the player was off. I figures it had just went to sleep but when I try to turn it on it hangs at the ibasso screen. Hard resetting has the sameresult and taking the battery out is the only was to turn it off. I tried removing my SD card and such with no luck. I also tried pressing various button combinations to get in recovery.
Also unrelatd... The playback buttons on my device have become somewhat wobbly and creaking the past week or so.
Don't know about the buttons, I have used mine so much they are shiny.
So have you plugged it back into your computer and gotten rid of any file on the DX50?
