If your Nokia 9300i smartphone is running very slowly, hanging, you want to bypass the screen lock, or you have a full memory and want to erase everything, or you want to sell or give it away and want to ensure that nobody can access your files and passwords, you can do a factory reset to restore it to its original state like the first day.
There are three types of reset for a Nokia 9300i: the “soft” reset that restores the phone's settings to their factory state without deleting any files, phone numbers, ringtones or installed applications, the “strong” reset that deletes all the content of the phone, it is a total format of the device including the contacts, ringtones, photos, videos, applications, etc. and finally the “total” reset that should be used when the phone does not start or does not turn on and it would be our last resort to recover the Nokia 9300i.
