This method of master resseting your device is particularly useful if you’ve forgotten your passcode or you are locked out of the phone. Let me tell you from the start that this is also a version of the Factory reset that you know, but the difference is that you will have to go through the Recovery mode to do this. Unlike the Factory reset, this one actually reformats both the cache and data partitions to delete all possible corrupt system caches, files and data that might be causing the problem.
Yes, a hard reset may also help with a blank or frozen screen, apps crashing or freezing, keypad/touchscreenissues, the fact that the device started making noises, can’t make or receive calls, that it won’t sync and so on. This is a very simple procedure, but also very helpful in bringing your phone back to life.
However, perform a factory data reset using this process only if it is absolutely necessary as it removes all data including: your Google account, System and app data, App settings, Downloaded apps, Media (songs, pictures, videos), so be sure to have a backup in place if you wish to keep your data. Also, if you have encrypted the data on your SD card, be sure to disable encryption before these steps. Otherwise, you will never be able to view your encrypted files again
