5. How to turn on the encrypted phone option?

The first method is to encrypt with a mobile phone lock.

You have to lock the program that opens the file with your mobile phone lock. You can't open the program without a password, so as to achieve the purpose of file encryption.

The second method is shift encryption.

Just put the files you want to hide in a hidden folder, such as System, so that your files will not be displayed. This method of hiding files is very useful, but finding this hidden file is very annoying. Of course, having a computer is another matter.

The third method is to change the suffix encryption.

Use your own file management to change the suffix names of pictures, videos and sound files, and then the changed files will not appear in multimedia. If you need to see them, just change the suffix name back.

The fourth method is to encrypt with the file lock Best_Crypto.

This software can encrypt files in various folders of mobile phone C/D/E, such as,, sis, 3gp, etc. It is the early encryption software of S60 third edition, and its encryption method is to copy the original file and encrypt it.

The fifth method is to use file force encryption, Y- manager or Q- manager.

Change the properties of the folder to hidden, and then move the files that need to be encrypted to the folder. However, in practice, it is found that files that have been searched in multimedia can still be found in multimedia even after the files are moved to hidden folders. The solution is to change the file name after the file is moved to the hidden folder.

The fifth method is to use telephone wizard to encrypt.

The encryption function of the telephone wizard is extremely powerful, which can encrypt short messages, call records and files. Here I only talk about the method of file encryption: enter the telephone wizard-file manager-enter the password (if the password has not been changed, the default is 123)- find the file to be encrypted-options-encryption (if multiple files are encrypted, mark them first and then encrypt them). The telephone wizard can only encrypt files, not folders. You can use Y- Manager or Q- Manager to view encrypted files, but you can't open them. When decrypting, just enter the file management of the mobile phone wizard, click Options, and then select Decryption.

In order to prevent others from seeing the private files on our mobile phones and bringing unnecessary troubles to our lives, you can choose to encrypt the private files. We all use the above methods, and each has its own advantages. If you have other good ways to encrypt mobile phone files, you can also exchange them.

6. My mobile phone is locked. Is there any way for me to unlock it myself?

Let's talk about forgetting the password of the boot lock and entering it incorrectly three times. I can't start it. I can't access the system. After entering the wrong boot password for 3 times, the system automatically locks the card, and I need to enter the PUK code as soon as I boot. Yesterday, the mobile phone card was accidentally locked and could not be opened. I need to enter the PUK code as soon as my mobile phone is turned on. I tried many methods, including installing mobile phone lock software to calculate the 10 digit mobile phone lock password. After searching many related posts on the Internet, I finally understand that the puk code is very simple. When you buy a sim card, the PUK code is in the envelope, or when you buy a card, you find that the original card is a mobile phone card the size of a business card.

The card we put in our mobile phone is only a small part of this card the size of a business card. Look at that business card with PUK code. Mine is. After entering, you can clear the previous PIN code and reset it. At this time, you only need to set a new 4-digit password to confirm that the machine can be turned on. If you can't find the envelope and the original mobile phone card (that is, the mobile phone card of the size of a business card) when you buy a sim card now, you can't find the PUK code. I used a Shenzhouxing card with a PUK code on the back. It is not excluded that other types of cards may not have written PUK code. Everyone should find another way by himself.

3. Enter your mobile phone number at "Please enter your mobile phone number:" in the "User Area" and then "Submit". 4. At this time, the homepage of "Mobile Website" of the province where your mobile phone belongs will pop up. Then you can enter your mobile phone number, password and verification code used when checking the phone bill, and click "Login" to enter your "User Zone".

5, electric shock data query 6, click "PUK code query", it will display the PUK code of your mobile phone. 7. At this time, you only need to enter the PUK code in your mobile phone to unlock it.

Finally, there is a well-known method. Go to the mobile business hall and spend some money to help you understand this method. It is not recommended to go as a last resort. After all, it costs money, and queuing will take a lot of time, but if it is not unlocked, it must be controlled within 10 times. The card will be scrapped if it exceeds 10 times, and it may cost more money. This is my experience in unlocking my mobile phone today, and I hope to share it with you. This is helpful .. If you encounter problems such as MMC locking, please read the second page. Please introduce PIN code and PUK code according to your needs. There are four kinds of SIM card passwords: PIN code, PIN2 code, PUK code and PUK2 code * * *. The initial codes of these four types of passwords are provided by China Mobile, an operator providing SIM cards. The relationship between the four types of passwords is as follows: PIN code (PIN 1 If it is not modified by the user, the original password set by the operator is 1234 or 0000.

If the startup PIN code is enabled, you must enter a 4-digit PIN code after each startup. The PIN code can be modified to protect your SIM card from being used by others. It should be noted that if you enter the wrong PIN code three times in a row, the phone will automatically lock the card and prompt you to enter the PUK code to unlock it. At this time, it is close to the dangerous edge. Therefore, if you modify the PIN code without authorization, you must keep it in mind.

PUK code (PUK 1) consists of 8 digits and cannot be changed by users. When the PIN code of the mobile phone is locked and prompted to enter the PUK code, don't act rashly, because the PUK code can only be entered 10 times. If it is entered incorrectly 10 times, the SIM card will be permanently locked, that is, scrapped.

The PUK code of some SIM cards is attached to the card when the user buys the card, such as Shenzhouxing of China Mobile, while the other part needs to be obtained from the network operator. If your password is locked and you don't know the PUK password, don't enter it casually. At this time, the correct way is to call the service hotline of the operator to which the SIM card belongs. After checking the user data, you can get the PUK code and unlock the phone. This service is free. Use PIN2 code when setting up mobile phone billing.

If the input is wrong for three times, the mobile phone needs to be unlocked with PUK2 code, and the process is the same as the PIN code and PUK code introduced earlier. However, these two passwords are related to the network billing and the modification of the internal information of the SIM card, so they will not be made public, and even if the PIN2 password is locked, it will not affect the normal use of the mobile phone.

Therefore, PIN2 code and PUK2 code need not be deliberately ignored. Puk is to solve the pin code The default pin code is generally 1234. If you make three consecutive input errors, you must use puk code to solve them. The puk code is in the envelope when you buy the sim card. You can also check it on the local mobile website or go directly to the mobile business hall to solve it.

After the puk code is incorrectly entered 10 times, the sim card will be scrapped immediately and must be replaced. Finally, I will send the software to unlock the phone. Just open the back cover and battery of the mobile phone or enter *#06# on the mobile phone to see the serial number of your mobile phone. Enter this serial number into the installed software to calculate the unlock code. Many friends who use Nokia S60 smart phones know that our memory card has a password and can be locked. You don't want anyone to know. This method introduced below is another problem of Nokia -QD Company. QD password is letters, only letters, or uppercase or lowercase.

It is circulated on the Internet that the password cannot be changed, which is actually caused by some people who don't have to. I always thought the initial password was 12345, but it wasn't at all. I typed it wrong! First, install SeleQ management software in the mobile phone, and then start it. 1. Enter the directory c:\system\ and find the "mmcstore" file.

2. Copy this file. 3. Paste it into a folder on the E: \ disk.

4. Rename the file after pasting. 5. Add a suffix ". Txt "file, change its properties to a text document.

6. Open this document. 7. The password came out. The first line is the attribute of MMC card, and the second line is the password.

I set it to 12345. 12345 is displayed here.

Ok, let's see if your password problem has been solved. Here's another way. If your mobile phone has a lock code and you forget it, and your mobile phone is not locked, you can unlock it in the following ways. What if I forget the lock code? Install Psiloc_sTools enhanced alarm and flight mode software or Psiloc_TaskMan task management, and choose to restore the original factory settings after registration, which can restore the lock code to the initial state.
