You probably didn't read the flash tool tutorial (or didn't care about the warnings in that), and flashed your phone in format all + download mode.

Hey,Maybe you can help me now with anothernewbug...
When i'm charging my phone, my microphone doesn't work. There is just an annoying noise. It is just when i'm charging my phone, otherwise the microphone quality is very good!
