My phone was full of data and had a problem
It was stuck on the black screen with white Apple logo mark.
I connected my phone to my Windows computer by cable then pressed volume up, volmome down then pressed the power button until the recovery option came up on the phone.
iTunes realized there was a problem and it said you need to update so I did that but as the phone was full error 14 came up just saying it was too full to do the update and fix everything.
I did the full recovery as it said but now I had iOS 14.2 on my phone and the older backup was from an older version so I couldn’t just do a recovery from there.
Backup First
Audio Files – Sync in iTunes then copy from folder on PC. Find where files are from Properties in iTunes.
Contacts – Make sure there is enough room in iCloud then backup
Photos – Install iCloud drive then copy files from it to your desktop
If you open the file you can check which version you need. For me it was 14.0.2
Download the old iOS file

1. Hold down Shift (PC) or Option (Mac) and click the Restore button.
2. Find the IPSW file that you downloaded earlier, select it and click Open.

They are not signing IPSW files anymore so I tried downloading AnyFix but that program said there aren’t any older supported iOS downgrades available…
Now I need to find a way to downgrade iOS…
