try with a fully charged battery

Question:

1. can it charged on pc usb cable?
2. when i press n hold "C", the screen should be black blank or keep blinking? (mine keep blinking, so make windows detect the phone on white screen and then undetect the phone on black blank.) Thats was my main problem
