how to unlock my iphone 13 from restore mode?
Yesterday I saw there is a software update from apple on my iPhone 13 Pro Max, I pressed the download button, then I needed to use my computer, and I thought to connect the phone to the computer and have a full update.
I did not install the software on the phone, I pressed install later on the phone and connected to the computer to have a full update and back up on the computer. After pressing update, the screen says there is an error 2015 and not possible to update. Then I get another message that this software has an error and must restore. I pressed update and then restore because I backed up the phone 9 days ago, but still the system tells me not possible to restore error 21.
Now I need your kind help to find me a solution please, my whole life is on the phone and it is frozen with the frozen phone.
