Hi people, I tried to update the software of my Xperia arc using PC Companion, but it failed in the middle of the update. Now when I turn the phone on, it displays a phone with a yellow exclamation mark, then restarts and the same story again. I found this page on Sony Ericsson website: Xperia? arc - Software update failed - Learn more - Mobile phones - Support - Sony Ericsson But when I plug the phone to the power outlet or to my laptop to be charged, it turns on and shows the same thing I said above, and restarts over and over again. I supposed it was fully charged so I tried connecting it to my laptop and ran PC Companion to try to repair, but because the phone keeps restarting, it fails. It's really frustrating. Please help me out.
