I just bought a brand new HTC 8x on eBay. I turned it on and set everything with no problems. But when I put it on the charger the indicator light was flashing red and then green. So now it doesn't charge it just stays at one number. Even tried my 521 charger. I thought maybe letting the battery die to see of that work but now it just vibrates and goes to the battery icon with a question mark. So any ideas?
