Grid, in a nutshell, is similar to one-click restoration of a computer. Grid is generally carried out when there are too many junk files in the mobile phone, serious errors cannot be recovered or the mobile phone is abnormal. Grid will empty all the contents of disk C and then write new system information, so please back up the data and materials you need before grid.

there are three kinds of gridding methods: soft gridding, hard gridding and through software gridding.

soft grid: after entering *#737# on the mobile phone, you are required to enter the lock code. The initial password is: 12345. If you have changed the password of the mobile phone, it is the changed password (not the password of the SIM card). After that, a white screen will appear, only the word NOKIA will be displayed, and it will be completed in 3-5 minutes. After the grid is completed, re-enter the mobile phone time.

hard grid: for S63 version, turn off the machine first, and press and hold the "green dial key, * key, 3 key+power key" while turning on the machine until a line of progress bar appears at the top of the machine screen, and then let go, and then reset the time.

for S65 version: turn off the machine first, and press and hold the "green dial key, red hang-up key, camera key+power-on key" while turning on the machine until a line of progress bar appears at the top of the machine screen, then you can let go, and then reset the time.

N97 and 97mini grid machine method: open the keyboard and hold down "shif key in the lower left corner, delete key in the upper right corner and space bar in the lower right corner" before turning it on.

Some S65 phones don't have camera keys, such as C5-3. Turn it off first, then press and hold "Volume key+screen lock key+green dialing key+menu key", and finally press the red on-hook key to turn it on.

through the software grid: install the System Tools software, which has a formatting option, so you don't need to enter the lock code to grid the machine.

There are several points to be noted in the above grid machine: keep the power absolutely sufficient, and do not attempt to shut down the grid machine on the way, and do not plug in the charger, etc. If it is violated, it may cause serious consequences such as burning the machine. There is also a hard case that may damage the hardware of the machine a little. Never use a hard case unless the machine can't be turned on.
