1. The easiest way is to use the "Restore Factory Settings" function in the phone settings and follow the prompts.

3. Enter *#7370#, and the original password is 12345. The phone will prompt to restore all factory settings? The phone will restart, select Yes, and then enter the lock code. The default value is 12345. Enter and select OK.

Note: If some memory-resident E disk software (such as call enhancement, screen saver, etc. ) and Q9, T9 fonts, formatting in this way is invalid. Therefore, before soft grid, all these softwares should be closed and Chinese font files should be deleted before formatting can be successful. Font files are generally under system/font.

Hard grid machine

This method is usually used when the system is too chaotic to start:

Turn off the power, press and hold the call key+No.3 key+* key+and then press power on. Don't let go, then a line of English appears, and formatting begins.

This formatting is thorough, and there will be no problem of invalid formatting. Others:

Press the * #+power button to turn off the machine and start the grid machine without any hint. Note: when formatting, ensure sufficient power, and generally run at full power. It is best to uninstall all the software first, and then see if there is a similar "system error". If there is no similar "system error", then proceed to the grid machine. Don't try to turn off the phone or plug in the charger on the way to the lattice machine. Try to put the soft shell first.

The software originally installed on the MMC card will be affected after the grid machine, so under normal circumstances, the important data of the MMC card will be backed up and then formatted, and all programs saved on 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 program management-take out the MMC card-check whether there are system errors-format the mobile phone-install the MMC card-format the MMC card (at this time, the mobile phone is the purest basic system)-install the programs that need to be installed-restore the address book-and complete it. ~~~~~~~~~~~
