hello I have a lumia 521 that I love to death, but i was prompted to download the update, and now it has been on the running gears screen for two days. I have tried all of the ways to correct this posted but none have work. I think they only work for the 920 not the 521. I have contacted tmobile and sent me to the store who could not do anything. I have done hard reset and soft reset. I have did the up down power down several times nothing works. Please Help!!!!
