What should be the problem before the phone is formatted

Methods and precautions for formatting mobile phones.

a.Soft Grid Machine:

Enter * on standby, and your phone will prompt "Restore all original phone settings?" The phone will restart. Select "Yes", and then enter the lock code, the default is 12345, and select to confirm after entering.

Note: If you boot up and start the e-disk software (such as call enhancement, screen saver, etc.) and Q9 and T9 fonts, it is invalid to format them with this method. Therefore, before the soft grid, close all these software, and delete the Chinese font file before the format can be successful.

The font file is generally under system fonts, please change the name to the fonts directory to delete the font file, and then delete it.

Remember to back up your business card holder, otherwise all contacts will be lost.

b.Hard-grid machine:

This method is generally used when the system is so chaotic that it can't be turned on

Turn off, press and hold the call button + 3 number button + * number button when turning on, and don't let go until the NOKIA logo appears.

This formatting is more thorough and does not cause invalid formatting.

Other: Turn off and press the * + power on button, and start the grid without any prompt.

Note: Sufficient power must be guaranteed when formatting, and it should generally be operated when it is fully charged. It's a good idea to uninstall all the software and see if you get any similar "system errors".

If there are no similar "system errors", then proceed to the grid. Do not attempt to shut down the machine during the grid, do not plug in the charger, etc. Try to prioritize the soft grid.

The software part that was originally installed on the expansion card will be affected, so under normal circumstances, the important data of the expansion card will be backed up and then formatted, and all the programs saved in the E disk will be reinstalled after the format of the mobile phone is completed.

In short, the most thorough formatting steps are: uninstall all the programs that can be uninstalled in the program management - take out the extension card - check if there is a system error - format the phone - install the expansion card - format the expansion card (the phone at this time is the purest basic system) - install the programs that need to be installed - restore the address book - complete.

c.Precautions before and after the lattice machine.

1.Use a PC suite or similar backup tool to back up the data on the C drive.

2.Back up the configuration files of commonly used software.

3.Back up the game's save file.

4.It is recommended to back up the data of the memory card after the grid and then check the card.

5.If the language changes to English, you can enter it.

Tools --- set --- --- personalize --- language --- phone display language ---Chinese.

Back up first, take out the SD card and format it.

Formatting is to delete everything in the disk and redivide the sectors.

Factory reset, except that the original settings are the same as when you first bought them, and it doesn't affect your files.

First, the main body is different:

2. Formatting: Delete all contents in the partition.

Second, the deletion content is different:

Third, the applicability is different.

1. Restore factory settings: only system problems occur, and the restoration design includes time settings, network settings, etc.

2. Formatting: Formatting is only necessary when the software is confirmed to be faulty.

Note:A factory reset is to restore your phone to its factory state. This operation is equivalent to system recovery.

There will be formatting operations during the operation, and the original operating system will be written. So, after restoring the factory settings, the data recovery is lost and some data cannot be recovered.
