12.4 update ruined iPhone 6 plus
I updated my iPhone 6 plus to 12.4 from 12.3 and it has practically bricked it. The touch became non-responsive 90% of the time. I've spent days trying to get into my phone and, when it would actually respond, would try turning off as much as I could in settings and deleting apps. I should add that I first updated all apps before the 12.4 update and it was a little glitchy after that, but continue reading. I finally was able to make a backup to my computer and reset the phone to factory settings and then restored the backup. It was still bricked after that so when I was finally able to get the touch to respond, I completely erased it again. This time I have not restored the backup and it is still not responsive to touch. I'd say it might be a little better but it seems that it wasn't an app causing the problem because I haven't installed a single app on it that didn't come from Apple's factory default. This phone was also not dropped or damaged that I know of. It does have a crack on the glass that has been there for several months and never caused a problem. I'm about to take an old 6 and try to restore my phone on it but am making a backup of it's 11.4.1 version that is currently working on it so that if the 12.4 version I backed up on my phone bricks it, I can, hopefully, restore it. Unfortunately, I have everything saved on my phone and have a good backup of it but can't use it if I can't get into any of it. Any ideas? I have pretty much erased and reset everything I could and turned off most settings.
