iPhone 7 plus stuck on Apple logo after reboot
I bought an iPhone 7 plus from someone and they had the 11.3 Beta iOS installed. Whenever the phone is rebooted it gets stuck at the Apple logo and requires me to go into DFU mode and do a full restore through iTunes. I tried doing just an update and it still freezes after reboot. iTunes did change the iOS version back to the stable 11.2.6, which is what I wanted, but if the phone is shutdown or rebooted it gets stuck every time, I've done it five times now. I even attempted to restore the iOS 11.2.6 from my computer using the IPSW backup and the same problem occurs. My phone does have a home button issue but the Assistive Touch works fine once I am able to get back to the working screen again. Please help me figure out how I can turn off my phone and I don't have to restore it every time I turn it back on.
