I guess that it is not enough battery, but my phone didn't charge. I just want to charge battery so that I can flash full rom.

Hope that every one will help me. Thank you very much.

Edit: I can flash stock kernel but didn't see Sony log and charging screen and charging icon. After flashing stock kernel (I tried GB, ICS and JB), I plugged into wall charger, RED led was on, after 30 minutes the screen light on but just a white screen, no Sony logo. What should I do next to see charging screen? Please help. Thank you.

Edit2: I revised log file again and see that:

01/050/2014 12:50:49 - INFO - Processing of partition-image.sin finished.

Is this a reason that my xGo couldnot boot? any solutions?
