What's with the white screen on the mobile phone?

White screen is generally caused by the problem of short message MCE, memory damage, system error, media being closed, game being installed or deleted, game running (CS, DOOM) and other reasons. Here is a detailed introduction to the solution to the problem caused by SMS!

For example:

When sending and receiving short messages normally, the database error is suddenly prompted, and then the system error occurs. After repeated several times, it will automatically turn off, stay on the Nokia screen for a long time after being turned on again, then the top of the screen will flash, the white screen will restart, and then the Nokia screen will appear again, and then turn off after repeated several times.

Solution steps:

First, unplug the card and turn it on, and check the Index.dat file under the directory C:\system\Mail. This file is the index of all short messages. If it is damaged, it will cause the short message reading to be abnormal, and then it will not be able to boot. If you can use the method of charging the keyboard (method 3) to enter the color screen, you will find that the SMS function is not displayed and the SMS menu in the menu disappears. Then all we need to do is move this directory to the E disk, which is the MMC card. You can solve this problem by using MsgDriveE (that is, moving text messages to e disk). It doesn't matter if Index.dat is damaged. Unplug the MMC card and turn it on, because the E drive is gone, and the system will automatically define it in the Nokia \ mail of the C drive. We just need to connect the MMC card to the card reader, delete /nokia\mail and reinstall MsgDriveE.

Press and hold the pen key to turn on the phone first, and then press the check key (Enter key) after the Nokia logo appears.

Secondly, if not, please try the following:

1. Take out your mmc card.

2. Load the card reader.

3. Enter the computer and read the data.

4. Delete the recently installed files in the mmc card (if SIS files are installed, you can use SIS Viewer to decompress the installed source files and then come back.

Deletion of comparison).

Third, if the second method is still a blank screen, then continue to use the "shutdown charging method":

When closing the battery, you can "forcibly open the battery to make the button effective" (this is very important, under normal circumstances, opening the battery is completely ineffective).

1. When charging in the power-off state, you will be prompted with an error and ask for confirmation. At this time, it will not be able to charge normally. Just confirm as required.

If the system prompts the error for many times, it will confirm the error for many times until it can be charged normally.

2. Remove the battery and sim card, and then install the battery after a period of time. Charging, before displaying all errors, continuously use "pen+power key" to restart.

Until the "NOKIA" sign appears on the screen, release the power button, and you can enter the safe mode after success (the system will not enter the safe mode when it is running normally.

Mode).

3. If you still can't boot, press and hold the pen key, press and hold the power key at the same time, and then press the OK key quickly and continuously. After success,

You can enter the mobile phone menu interface.

4. Unplug the charging connector, then connect the sim card, and repeat the second step to make QD think that the environment is normal and the system is wrong.

5. Take out the sim card, connect the battery, don't connect the charging connector, and then turn it on. When you see the lovely (and hateful) Nokia, plug in the charging connector immediately.

, enter forced mode, press the power button to start the machine.

6. If the last step is successful, you can see a lovely desktop, prompting you to insert the sim card. It tells you to insert it. How can you just plug it in without plugging it in? (

If not, shut down and restart, and you will see a color screen prompt.

4. If the above methods are ineffective, the following methods can only be adopted, but they can usually be solved.

Any white screen problems caused by software problems.

First of all, you should have a card reader and a computer. After taking out the card, start the machine, and then insert the card back into the phone. If the card name is set, please delete it, delete everything under C:/system/program, and keep the folders of app, data, fonts and RECOGS in E:/system/. If you delete the others, turn it on and see if it can start smoothly. If you don't change the card name, delete everything under C:/system/program, keep the folders of APPS, DATA, FONTS and RECOGS in E:/system/, and delete others before restarting. If you still can't get in, follow the following methods.

1. After taking out the card, cut all the contents on the card to the computer through the card reader to create a temporary folder. Then put the card back on the phone and start the machine to see if it can start. If it still can't start, please insert the card after starting, copy the folder C:/SYSTEM/DATA and APPS (including all files of your mobile phone and programs) to your card, and then cut and paste it into your computer for later use. Then please format your phone thoroughly:

*#7370# (If you can't format it completely, please download the font deletion tool, usually the font is working). The initial password is 12345.

2. After the machine is turned on or formatted, put the card back into the card slot and format the card again through the mobile phone. This process takes about 20 minutes (5 12M RS-MMC takes about 20 minutes).

In this long process, you can modify the files cut from the card and mobile phone in the computer. Keep the folders of app, data, fonts and RECOGS in E:/System/ first, and delete the others. The MIDP file is a file for saving the programs in the treasure chest. You can cut it into the root directory and reinstall it later, because all the JAR programs used are stored in it, and you can choose to install it directly through SELEQ.

If there are no grid friends, you have to delete everything under C:/system/program.

Keep it. APP and. The DAT file in c:/system/data/file is copied from the mobile phone, and the others are deleted. After the mobile phone is started, play it all.

Copy it back to the phone.

4. After formatting the card, it is best not to change the name of the card, just set it to none. If you really want to use your own personalized card name, it is not recommended to use Chinese. keep

All files on the computer are cut back into the card and then turned on.

5. If you don't have a friend who checks the machine and it is still stuck on the Nokia screen when you turn it on, please check the machine once and then follow the above steps.

To solve this problem, it is generally not necessary to format the contents of the card.

6. This operation can generally solve the problem of fake white screen. At the same time, I advise everyone to back up their own apps and business cards under C regularly, just in case.

Just in case!

7. Reminder: It is best not to change the card name, just set it to none.

It may be the conflict caused by the mobile phone and the computer reading the name (volume label) of the card at the same time.

If it still doesn't work, please go to a special maintenance station. Good luck!
