I charged it overnight with the SD card out, reset it, and it is still stuck on the same page.
I am thinking it is probably some kind of hardware failure.
Now I am trying to decide whether to do an RMA at newegg or get with customer service at Astak. I am shooting for "quickest turnaround" since I was really enjoying the thing before it croaked.
Has anybody had any experience with Astak support as far as getting a unit replaced? How quick are they?
