0. Done. The above is still not good to send customer service for repair!

Take out the memory card and try it, if it still doesn't work, it's best to go to a Nokia repair point to check it.

The landlord takes a breath, don't worry, listen to me tell you.

1.The white screen problem is a common problem of Nuo Ji,First take the card machine,If it still doesn't work, it's a system problem,S40's are like this,Flash processing。 30-40rmb to get it. I used to flash the white screen of my mobile phone!

2.If it still doesn't work, it is a hardware problem, it is recommended to send it to a large mobile phone repair point for repair, not a battery contact problem, it should be a cable or which part of the motherboard has a problem.

It is recommended to replace a battery to fit, my ** has fallen before. Then just like you, change the battery, which is caused by poor battery contact.

It should be a motherboard problem, it is recommended to find customer service and ask him to help you fix it.

Step by step:

1. Disturb the SIM card and take out the memory card, if the screen is not white when booted, you can troubleshoot the hardware failure. On the contrary, if there is a hardware problem, send it for repair.

2. Install the SIM card but take out the memory card, if the screen is not white when booted, it means that it is a problem on the memory card, you can try to check the card.

3. Anka also takes out the memory card, and the boot is still white, which means that it is a software problem in the mobile phone, and you can try the grid.

All operations should pay attention to saving the data in the mobile phone in advance.

There are two possibilities.

One, white screen, system error, to flash the machine, (sent for repair).

Two, it's not broken, it's just slow to boot, up to 5 minutes, (I encountered it before, 5320, it took ten minutes to boot, and I played with the machine for several years).

I have a way, I figured it out myself, if you finish the C drive, just take out the memory card, and then press the ,3,and dial button,And then press the power button,It's absolutely fine。

It's the same with my phone. It's time to change the screen. The boot is either a white screen or a flash. Slowly, it flashed white. Tragedy.

Try to kill with a 360 Trojan horse and kill it.
