I've tried to force restart using power button + volume up (switching off using the power button alone doesn't respond) several times but it still get stuck in the same screen. I was able to repair it using PC companion and SEUS (both were successful) but when I turned on the phone the problem still persists. Restarted several times but to no avail. I cannot use my phone right now.
What seems to be the problem?
My phone is less than a week old, unlocked, stock and not rooted. I will try to flash 4.0.4 back using flashtool coz it was working fine before the JB update.
