6670 often turns off automatically with a white screen!

It may be a software conflict, remove the memory card and delete the recently installed program normally.

If you can't do it, you can get a grid machine and a card.

If you can't do it, you can only go to customer service for testing.

There are two ways to use the grid machine (remember to back up the data you want before the grid machine, etc.):

1. Soft grid: enter * on the mobile phone, after which you are required to enter the lock code, the initial password is: 12345, if you have changed the mobile phone password, that is the changed password (not the SIM card password), and then a white screen appears, only the word nokia is displayed, 2 3 minutes after the grid is completed, re-enter the time;

2. Hard grid: turn off the computer first, and then press and hold the dial key, "* key, and "3" key when turning on the computer, and turn on the power until the word "nokia" appears (you can't release any button during this process). Wait a few seconds until "formatting...... appears", then you can release the above buttons.

After a few minutes, the system format is completed, and the phone automatically restarts and enters the standby screen.

The above grid machine needs to pay attention: keep the power absolutely sufficient, do not try to shut down the grid on the way, can not plug in the charger, etc. Also, try to give priority to the soft grid. 6670？？？Isn't it, this machine is very stable, and it can't be soft or hard?

This problem is very difficult.,My machine has never appeared.,Is it a problem with the program you installed?,It's really not good to check your memory card (the machine and the memory card are grid at the same time)。

If it doesn't work, it is estimated that you will have to go to the manufacturer, and if the manufacturer can't solve it, you will have to go to the garbage station!!

First of all, make sure that it is not a software problem, and it has nothing to do with it. It's the internal hardware that's broken, and mine has had this problem, so you have to get three packs to nokia customer service for repair as soon as possible. If you don't have it, you'll have to spend money to repair it.

I don't worry about repairing it in other places, so I went to nokia customer service to repair it, and I was asked for 350 yuan [faint]. If you don't repair it, you can't use it, and I'm helpless.

Mobile phones often have this kind of problem, you can take out the SIM card and install it well, so that you can open the machine for a while, but it won't work for a while, you'd better take it to repair, the mobile phone repair company should be easy to solve this kind of problem.

Just check the machine, and there is no big loss, that is, take the ** book to the MMC or mobile phone card in advance, and then take the test back after the grid is completed.

In that case, it will be fine.
