All too often, some serious iOS glitches that lead to this mess may not be resolved thoroughly by updating iPhone software, but by updating the firmware package. The best and direct way to do it is to use Joyoshare UltFix, a third-party program that is created to repair various iOS issues existing on your iOS device. It works by downloading a new firmware package for your iPhone to cover the previous one. Thus, you need not have concerns about data loss in the whole process.
To be more specific, this tool is carried with three modes to repair diverse problems, recovery mode, standard mode, and advanced mode respectively. Recovery mode, as the term suggests, is focused on helping your iPhone get into/out of recovery mode with one click. What about standard mode? Well, this mode serves to repair many common iOS issues without losing any data, containing Facebook notifications not working on iPhone, Instagram keeps crashing, app not updating on iPhone and more. As to advanced mode, you are able to use it to address some knotty problems or the issues that can not be fixed by standard mode. One more thing to introduce is that Joyoshare UltFix is applicable to all iOS devices even Apple TVs and iOS 13.
