There are types of iOS errors related to our devices, such as Apple logo stuck, black screen, boot loop, white screen, no service, etc.
Usually, the basic solutions, like restart, hard reset, update iOS, can be tried.
However, if you can make sure no hardware problems, it's possible to repair the system with an
iOS system recovery, like Joyoshare UltFix, 3U, etc.
The best thing is that I don't have to worry about the data as there is no data loss.
