My HD2 is not booting up at all, just vibrate and show a black screen, I tried to load from USB but still the same, More over cannot even update any ROM as it hangs in 0%. I have my data (contacts n stuff) is there a way to remove everything and reinstall from factory ?? Even the factory hardreset didnt help me as i m able to restore by pressing the VOL up n down key + power key but it says 100% restore (which takes 3 - 4 sec.).
