I started a security wipe on my Z10 around 2 hours ago. It's still going on, and the phone switched off itself twice during the process. When I switched it back on, the printer like picture's still there, and the circle's still spinning. There weren't many apps on it, and I had around 100 songs saved on the device. Please help! I'm terrified of having a brick for a phone that's only 4 months old!
