Nokia 6300 shuts down and restarts on its own?

My phone is also I asked customer service and he said it might be a battery problem I didn't change it You try it yourself.

1. Change the battery and try 2 Don't insert the card, it may be that the card is toxic or software conflict or file error, so you have to check it on the computer 3 Make sure that the above methods are useless, it can only be a mobile phone problem, the next antivirus software check the virus, or restore the factory settings; 6300 doesn't seem to be qualified, and it can be qualified, so I'm afraid that it will crash and become a brick halfway, so take it to the repair shop, maybe the hardware problem may also be the system, and the system problem will be brushed, less than 50 pieces....

If this did not happen before, it is recommended to reinstall the backup of the contents of the card, and it is recommended to reinstall it once a month.

There is only a problem with the battery.

1.The battery is aging and can't hold power at all, and although the display is full, it quickly runs out. This is easy to do, replace the battery.

2.Oxidation of the contacts, leading to contact problems. This is very common, take something to remove the oxide layer of the contact, sandpaper, etc.

3.The battery contact is not tight, the contact is poor, resulting in insufficient voltage, this is generally to find a way to pad the bottom of the battery, so that the battery contact and the mobile phone battery box contact as close as possible.

It can't be a problem with the phone.

So can you hit it? If you can hit it, you forget to hit it, and see if you can use it, I sometimes get it like this, 6300** is problematic.

There are two scenarios in which this problem occurs:

1. If the SIM card is broken, you can change the card. This is the most likely to be overlooked, always thinking that it is a problem with the mobile phone, but in fact the card is burned.

2,If you exclude the first one,Then it's the font logic is chaotic (the most likely to cause this problem if you have used the phoenix flashing machine),You can use jaf to reflash it,Restore the original settings。

The reasons for the general automatic shutdown may be as follows:

1. The protection circuit in the lithium battery is overly sensitive, so the current will be cut off as soon as it is large.

2 The battery itself is aged.

3. There is dirt on the metal sheet at the contact point of the battery, which causes poor contact with the power supply.

4 The joint between the battery and the mobile phone is prone to loosening.

If, after inspection, it is found that the first two problems are the first two problems, then it must be sent to a specialized repair shop for repair. If the latter two problems are caused by the oxidation of the dirty metal sheet of the battery, the situation will be improved as long as it is wiped clean with a glue stick. Putting paper or film between the battery and the phone can also solve the problem of poor contact caused by loose batteries.

Maybe it's a matter of software.,It's better to go to customer service to kill the poison.,Mine is like that.,Mine is 79.It's good to kill the poison.

Causes:1 Bad battery.

2 Clean the battery and electrodes of the phone.

It could be that there is a problem with the phone amplifier - repair.

You can go to the flashing machine to try it.

If you suspect that there is a short circuit in the card reading circuit, try to change to another card first, so as to eliminate the fault caused by a bad card. If it doesn't work, you have to replace the card seat, find a professional repair shop to replace it, be careful of the boss ripping off customers, and clearly tell the boss that as long as the card seat is changed, it will not exceed 20 yuan. Still doesn't work, clean the main version with ultrasound.

Not yet, you can also rewrite the software. If it doesn't work yet, there is no repair value.

It looks like the motherboard is faulty, send it for repair, but the relative repair value will not be cost-effective!

How easy to brush the dazzling flight stamp.

It shouldn't be the reason for the mobile phone card.

Mine is also 7500, I bought it in 08, and it was a similar situation last time, but now it's good, there may be two reasons:

1.The battery, my battery, has been used since I bought the mobile phone, the battery has power, but it just can't turn on, or the phone turns off automatically, and I changed it again last month;

2.program, you can restore the factory settings in the mobile phone by yourself, 2) if you can't do it yourself, you can go to the after-sales service store to let the sales staff help upgrade, they are more professional;

The above is just a suggestion, and I hope that your phone will be restored soon.

The mobile phone program is messed up, it is recommended to go to the mobile phone repair department to rearrange it again!

You can try to reset your phone once.

Hard method: 1. First of all, in the shutdown state, short press the power button to turn on, press and hold the volume reduction button after vibration, and release it after the white exclamation mark appears;

2. Immediately press the volume increase, volume decrease, power button, volume decrease, all press once and put it off.

3. The phone will automatically restart, and the gear will rotate on the screen after a while, and then the phone is really recovering, and the phone will become factory activated in a few minutes.

Please back up your data before resetting).

Note: Never use your phone and disconnect the data cable in the middle of the process.

Most of them are system problems and need to be flashed.
