Nokia N72 can t turn on the machine?

It may be caused by the installation of incompatible software, try to delete the recently installed software;

If it can't be started, you can only try it. Press and hold at the same time while powering off"Answer button"+"*"+"3"Three keys and then launch until the set region appears.

First of all, there is no difference in the quality of parallel goods and licensed goods.

I read your description and I think it's your battery that's wrong. Parallel mobile phone sellers tend to use their brains on other accessories such as batteries instead of giving you authentic batteries or accessories.

You can go and buy a battery yourself, buy the English version online, it's not expensive, or you can buy a Scud.

Try charging the battery with the universal charger and then turning it on.

In the most earthy way.

Unplug the panel and put it on again, see if it's okay, if you can't, you have to change it, you have to fix it

If there is a problem with the circuit board on the motherboard, or the battery is not in good contact, take it to a professional person to take a look.

There is such a problem after just buying it for a day or two, that is, the parallel cargo machine should also ensure some after-sales service, and find a place to buy a mobile phone. If it doesn't work, change the battery first, and look at the battery contacts of the mobile phone at the same time, if it doesn't work, it may be a problem with the mobile phone, the motherboard, and the installed software are possible. These problems are either flashed or repaired.

Good luck! In the case of licensed cargo aircraft, it is definitely necessary to find after-sales service.

Change the battery first! If it's useless, you can only fix it! ~

Maybe I didn't rush into the electricity.

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.
