For mobile phone repair experts, please enter the Nokia N72 can not be turned on and off

Feedback questions with them.

They will guide you.

It's a pity that there's no point in telling you now.

Seriously, I feel sorry for you.

Alas... 1. The liquid used to clean the mobile phone is generally alcohol, but some use Tianna water to carry banana water.

2, the boot chip is generally unlikely to be broken, it is estimated that it is the boot button, and the purchase price of that thing is no more than 8 cents.

3. Display chip? Our maintenance department hasn't fixed this thing, but the display is about 115.

4. You can go to claim compensation, but it depends on whether you are fierce or not, and whether he is willing to give.

5, if you don't go back, it's reasonable, do you think you can still go back?

You can rest assured that after our Central Asia mobile phone is listed, we will set up repair points in each province, city and town.

You have been fooled, like Nokia mobile phone has a problem, you can't just find a repair shop for repair, you should go to Nokia's special repair office to repair! There's no way you're going to get your money back.

It's not a big problem if you're really willing to spend money, maybe it's just going to be dust, and the money won't come back.

Mobile phone QQ is connected to the Internet through GPRS, this way is very power-consuming, equivalent to talking all the time, and it is normal for the mobile phone to run out of power, so try charging.

If it still doesn't work, then Cheerful Battery Try.

If you can't do it, you have to consider the hard grid machine, but you have to think about this, whether to go to customer service to repair it, or solve it yourself!

Here's how to do it: turn it off first, press and hold the dial key, "* key, "3" key while turning on the power, turn on the power until the word "nokia" appears, you can't release any of the keys during this process, wait a few seconds until "formating...... appearsword, then you can release the key. 3 After 5 minutes, the system format is completed, the phone will automatically restart and enter the standby screen, and re-enter the phone time.

Important!!

First, to keep the power absolutely sufficient, can not try to shut down the machine on the way, can not plug in the charger, etc., if it is violated, it may cause serious consequences such as burn-in.

Second, the hard grid may be a little damaged to the machine hardware, and the hard grid should not be used until it is absolutely necessary.

3. After the grid machine, the "line 2" will disappear, and it must be flashed to KF to recover.

I just use the n73, as long as there is no power, it will automatically shut down, and no matter how you press the switch, it doesn't respond, just charge. Do not worry.

You can't figure it out on your own. Take it and fix it.

You can go to a non-after-sales mobile phone store to brush the machine, and it doesn't take a few dollars. And now the quality of the brush machine in the place where the mobile phone is repaired should be guaranteed, and the technology is very mature. Then see if your phone is working properly.

If it can't be used normally, you can go to the after-sales service to change a board, or you can go to the place where the mobile phone is repaired to change a piece, but the quality is difficult to guarantee, but if the board is replaced in a more professional place, it can be used normally, but the life may be shortened, but it is cheap. It's up to you to choose. However, 2,000 yuan for a board is indeed expensive, it is better to buy another machine, even if you buy a parallel goods, you can use it for two or three years.

Your phone must have been flooded, or squeezed, or struck by lightning, and you go somewhere else to change the motherboard is not so expensive, hundreds of dollars.

You can look into the three-guarantee method, the phone is guaranteed for one year without human damage (motherboard deformation or liquid ingress), etc. If it is deformed or liquid ingress, the whole machine will not be warranted, and the deformation of the motherboard will not be visible if you don't disassemble it, and it will not have a particularly big impact when you use it in ordinary use. So you don't know .

You can return to the repair center, you just let him help you write the software, if you can write it for about 300, if you can't write it, you buy another one is more practical.

If you want to go to court, be cautious, the cost of mobile phone identification is very, very expensive, if you can go to court for 1 yuan, then you can try.

It depends on whether you update the system yourself to update the unofficial site, or go to the store to update, if it is unofficial, then there is no way, admit bad luck, you have no reason to litigate with others, Nokia did not say that you can update the system by yourself, to be honest, don't mess up if you are not an expert, change the motherboard of 2000, it is better to buy a new !!

It's a virus, try it on the phone.

Failby Sail Rush* - Soft grid. Only restore the system to factory settings, do not delete files, the effect is not obvious.

Standby input* – soft and hard. Restoring the system to factory settings will delete the personal data of the C drive. However, Line 2 cannot be retained, and it will return to its original state. Sometimes, the C drive file is not deleted with the grid after the machine, and the system is unstable.

3+1 key hard grid - hard grid. Restoring the system to factory settings will delete the personal data of the C drive. It is possible to reserve line 2 for sedan cars. It's the same as flashing. Recommended.

Hard operation method: (power off first).

Two hands are required, one hand is to press and hold , and the green call button, and the other hand is only to power on. You can't let go of the handshake until the screen formatting....It can be loosened, and after about two minutes, the phone will automatically turn on and it will be done.

The phone can't be turned on: press and hold the "dial key" + "3" button at the same time in the shutdown state, and then press the power button until the region and time are required to be set after the power on.

The general reason for the phone to crash: the phone restarts due to insufficient memory.

A software conflict leads to a reboot.

Genus series

Second Edition. symbian

Operating system. This system is more likely to crash than other second-tier machines.

And most of them are caused by software conflicts.

Because most users like to install a lot of extension software when playing smartphones.

As for plugging cards. I don't know if you're talking about a SIM card or a memory card.

If it's a SIM card.

It could be that the SIM card on your phone has been electrocuted.

That is, there is dirt or rust stains in the place where the card is inserted.

Proper cleaning with alcohol or hard objects will solve the problem.

Unless your phone is aging.

If it's a memory card.

It must have something to do with software.

Take the card reader and connect the card to the computer.

Save the files you need to your computer.

And then Geka. Remember to take tan.

After the computer is checked, you have to check it again after inserting the mobile phone.

Otherwise, it cannot be used.

And. Before the geka.

Do not back up files in the system directory.

Because the installed software is basically here.

It's the conflict they cause.

Of course it is best if you know which software is causing it.

Uninstall directly.
