Question: Can I update i OS on the device without unlocking it and without losing/wiping the data?
Here are 3 modes for you: Standard Mode, Advanced Mode, and Exit Recovery Mode. Next, the program will display a firmware that is compatible with your i Phone.
Sit back and relax until a message pops up on the program screen that your i Phone has been fixed.
After that you i Phone will have been restored to normalcy and now upgraded.
i OS has a lot of great features but in order to enjoy them you need to update.
If your i Phone or i Pad won't finish downloading, gets stuck while installing, or won't turn back on after it's turned off, don't worry.
