I went through most of these steps and still couldn't fix the issue. I advise updating your phone through iTunes this worked for me if any errors are coming up after pressing the update button on iTunes just disconnect your phone from the PC restart the computer and then connect your phone again and update. That should fix the error pop-ups
Itunes definitely worked for me. Thanks a ton for suggesting it! It's also free to use, so you don't have to waste money paying for something when a trusted program does it for free.
I'm not 100% sure but I'm positive that it won't be wiped out since it didn't happen to me just make sure you back up your phone through iTunes u will find the back up option right next to the update button
Who else i I s having this issue please I need assistance the video isn’t helpful at all cause you have to pay for the software and it wasn’t mentioned in the video
