The landlord can look at the information I found for you and see if there are any methods suitable for your mobile phone:

When there is a problem with the software of the mobile phone, I believe many friends will think of taking it to the mobile phone maintenance department for repair. In fact, if there is no hardware failure in the mobile phone, you might as well try to format the machine, and the problems you may encounter will be solved. Here's a brief introduction to the method of cell phone formatting.

For non-smart phones, recovering system data is particularly simple. Nokia's S40 operating platform, Sony Ericsson's A200 platform or MTK's solution can simply restore the system through the restore settings in the mobile phone settings. Of course, this recovery method will also empty all the information left by users. If it is too serious to turn on the computer, you can only write data and brush the computer by connecting to a PC.

S60 smart phone

Users who use Nokia S60 smart phones can shield their phones in case of software failure or obviously slow running speed. Nokia's S60 gridding method is not single. There are roughly three methods (you must back up the important information in your mobile phone before gridding):

1, Soft Cell: Nokia's S60 smart phone has a variety of commands, among which the command for soft formatting the phone is "*#7370#", and the data of the phone can be cleared and recovered by inputting this command when the phone is turned on. In this process, the user needs to enter the lock code (the initial password is: 12345). If the format is successful, the phone will have a blank screen and only the words "Nokia" will be displayed. The whole formatting process takes 3-5 minutes.

2. Hard Grid: Nokia's S60 smartphone supports another format called "hard grid" when it is turned off. Press and hold the dial key, the * key and the 3 key in the power-off state, and then press and hold the power key for 2-3 seconds until the word "NOKIA" appears. You can't release any keys during this process. Wait a few seconds until "Formatting .../.../"appears, and you can release the key. After 3~5 minutes, the system is formatted, the mobile phone automatically restarts to enter the standby screen, and the mobile phone time is re-entered.

3, through the software grid: another way is to format by installing extended software, such as SystemTools, which has the function of formatting mobile phones.
