I received mine yesterday, and within the first two minutes its rebooted!

I've tried flashing new firmware, NSU didn't work it got stuck at 3 minutes, using flasher I changed firmware to GLOBAL and then UK variant, nothing. Then I tried flashing the eMMC and it just says changing device to flash mode and nothing happens!

Now it doesn't even do that, tried it under windows XP(32) and windows 7(64).

This is not good! I've just paid £500 for this and I have to wait for a replacement! I want someone to bring it to my house and swap it! I don't want to be without for 3/4 days or more!

This is definitely a H/W fault, I've changed the battery, changed the firmware, deleted all stuff preloaded on the device and still reboots! I am not pleased!
