my phone won't turn on after updating ios 6.1
I've updated ios 6.1. The phone went off durign the night (it had 60% battery).
Now it only turns on plugged to the wall socket (not if I plug it to the USB port) and it shows the "iOS 6 Configuration" screen, telling me to connect to iTunes, but if I unplug it to connect to the USB, it turns off.
If I plug it to the USB, it keeps showing the little apple, and turns off, again and again. It never gets to the same screen of the "iOS 6 configuration".
I can´t seem to turn it on with de DFU mode plugged to the computer.
iPhone 4, iOS 6.1
