How to reinstall iOS on an iPhone without a computer or data loss
I previously found an article that described a process for reinstalling iOS on an iPhone without using a computer. The steps involved a specific sequence of button presses on the iPhone itself, which would initiate the iOS re-installation process. Once started, the iPhone would automatically reinstall iOS and then recover all data without any further user intervention.
I want to perform this process again but cannot find the original article. To be clear, I am looking to reinstall iOS without losing any data, not restore from a backup.
Can someone please provide the specific steps to reinstall iOS on an iPhone using only button presses on the device itself, without the need for a computer and without any data loss?
Thank you in advance for your help.
