Nokia 5320 smart phone formatting can repair the system

Due to the installation of too much software, the s60 system directory is messy, so I want to restore the mobile phone system to the factory settings.

Procedure:

A. Use the PC kit to back up important information on your mobile phone, such as contacts, text messages, and photos. In addition, the soft lattice machine does not delete the data of the removable memory card.

B. Perform corresponding lattice machine operations using the following methods.

Soft lattice machine:

1. The easiest way is to use the "Restore factory settings" function in the mobile phone settings and follow the prompts.
2. Enter * #7780 #, and set the mobile phone to soft-Reset (the phone number, information, and call/call number are saved after the cell phone ).

3. Enter * #7370 # And the original password is 12345. Will the mobile phone prompt to restore all factory settings? The mobile phone will be restarted. Select Yes, and then enter the lock code. The default value is 12345. Then, select OK. (
The method I use is like this.)

Hard lattice machine:
This method is generally used when the system is confused and cannot be started, or soft formatting is ineffective. This formatting is thorough ~~~ Shut down. Press the call key \ 3 \ * and

Press the open key. Do not let it go until "formatting..." appears on the screen. This format is relatively thorough and will not cause invalid formatting.

It should be noted that hard lattice machines are more harmful to mobile phones than soft lattice machines.

C. If the grid is not powered on, You can unplug the battery for about 5 minutes. It can be charged after it is started.

The lattice machine process is like this. After the lattice machine, the performance of my mobile phone is significantly improved.
