In the process of using the mobile phone, we will inevitably encounter some failures, or there are too many junk files in the mobile phone, and we want to clean it all at once. Rather than deleting them one by one, it is more convenient to format and reset them at once. However, there are two methods for a one-time format reset, one is to restore factory settings, and the other is to flash the device. Is there any difference between the two? Which clean data is more thorough? If you happen to have no idea, let's take a look.
Let’s talk about what is factory reset. Every mobile phone is pre-installed with a system when it is produced from the factory. The data of this system is directly written at the bottom of the mobile phone, so as long as the mobile phone is not seriously damaged, it can be used at any time. After the phone is restored to factory settings, first of all, the system settings will change the volume, default ringtones, desktop layout, widgets, etc., all of which are restored. The data in our music, pictures, files and other storage spaces will also be cleared. Some apps that were deleted by us and functions that were closed by us will all be restored. We originally authorized the system application, such as accessing the camera, obtaining location, etc., and all authorized content must be authorized again. All previously logged-in accounts have also been deleted.
At the same time, your system version, carrier description file version and other low-level files and information have all returned to the state when the phone just left the factory. Key information such as fingerprints and faces in the security chip will also be deleted when the phone is connected to the Internet after the phone is restored and restarted. If your mobile phone is enabled for multi-user login, other user data in the mobile phone will also be deleted. In other words, restoring the factory settings is equivalent to letting the phone sit on the "time machine" and returning all functions, data and APPs to the factory state.
Let's talk about flashing. There are many differences between the flashing process and restoring factory settings. The most obvious difference is that restoring the factory settings only needs to be operated on the mobile phone, while the flashing requires the cooperation of a computer and related flashing software. Compared with restoring factory settings, the flexibility of flashing is much stronger. Under certain conditions, we can choose to only flash the system, and all user data can be retained. Of course, we can also choose a brand new flashing machine, all data in the internal storage will be cleared during the flashing process, and any APP and system settings will be cleared. It can even consume more time, repeatedly erasing and writing to the internal storage to avoid being restored by professionals.
Of course, in addition to flashing the official firmware, we can also use some professional methods to flash some unofficial firmware. Unofficial firmware often has some playability, and functions that ordinary mobile phones do not have can sometimes be implemented in unofficial firmware. The fun of flashing is here. Of course, if you are not a professional game player, it is recommended to flash into the official stable version of the system. After all, it is easy to use and durable, which is the most basic demand for mobile phones.
In addition, for the iPhone, flashing will also affect the user ID of the phone. Due to the characteristics of the iOS system, on the iPhone, many apps and advertisements only use the user identification code to determine whether your phone is a new one. After the iPhone is refreshed, the user ID will change. If APPs and advertisements do not record other key information, it will be mistaken for a brand new phone. As a result, the private information about your personal interests and hobbies obtained by the advertising platform does not have a user identification code to correspond to it, and it will not push advertisements that make you easily interested. And restoring the factory settings will not change the user ID.
To put it simply, professional flashing is definitely more thorough than restoring the factory, and flexible. However, it is more professional and suitable for people with strong hands-on ability and a certain professional knowledge base. Ordinary users are recommended to try to restore the factory settings first. If it is really unable to meet the needs, then you can go to the official after-sales service to flash the machine.
