Hi, facing such a situation, you can put your iPhone into recovery mode and then try to restore it with iTunes. If failed, please continue to apply iCloud to remotely erase your iPhone. Doing so can also fix the problem, but this method requires “Find My iPhone” to be enabled on your device. Alternatively, using an iPhone unlocking tool is the other great solution to this problem. Many users have reported that such a tool called Joyoshare iPasscode Unlocker has the ability to fix such issues without any limitations and difficulty. Hope these ways can be useful to you all.
