How do I get my phone to start up?? Lg k22 will show lg logo then goes to white US Cellular logo blinks a few times and goes to black screen. I have tried the power button and volume down and it just does the same thing. I can't get it to reset or anything cause it won't go to any other screen. Does not have removable battery. Has a crack in the screen but worked fine until shortly after software update. Please help me fix my phone
