First, the basic knowledge:

The short messages of mobile phones are generally stored in the ROM of mobile phones, that is, the mobile phones themselves. Unlike the data in SD memory card, it can be retrieved directly. Therefore, the recovery of short messages is different from the recovery of general file deletion, and it cannot be operated by commonly used data recovery software. However, its storage mechanism is similar. After the short message is deleted, it still remains in the original storage location, and it can be recovered in theory as long as it is recovered in time. After research, Datang data recovery has successfully solved the problem of how to recover deleted SMS, which can be applied to most Android smartphones at present. There are two main ways to lose short messages on mobile phones: people directly delete short messages and mobile phones swipe their cards to lose short messages. This paper briefly explains the direct deletion of short messages artificially, and introduces another article about the loss of short messages caused by brushing the computer.

Second, the preparatory work:

To recover the short message, you need to prepare the mobile phone, data cable, mobile phone driver and the other party's mobile phone number.

Mobile phone driver: the mobile phone driver is used to identify the mobile phone after it is connected to the computer. Generally speaking, the system comes with a mobile phone driver, which will be automatically installed after connecting to the computer.

Counterparty's mobile phone number: refers to the mobile phone number of the other party who has short messages with this machine, and must be provided. If you can't provide complete numbers, you can also provide fuzzy numbers.

3, obtaining a short message database

Android smartphones use sqlite3 database storage mechanism (extension *. Db), and basically all the data generated by the program is stored in the mobile phone itself based on this database technology, and so is SMS. To recover the short message, it is an important step to find the database file in which the short message is saved in the mobile phone and copy it. How to find this database? Please look at the following demonstration.

1. Download and install the file manager on your mobile phone. Recommend RE manager. Please search for RE manager yourself.

2. Run the RE Manager on the mobile phone. After starting, click "Load in Read-Write Mode" at the top;

3. Click the directory/data/data/com.android.providers.telephone/databases/to find the file mmssms.db, which is the database file for saving short messages;

4. Long press the file to pop up a menu and select Copy;

5. Return to SD memory card in Re Manager and click Paste;

6. mmsmss.db has been copied to the SD memory card of the mobile phone;

7. Connect the mobile phone with a data cable, or insert the memory card of the mobile phone into the computer with a card reader, and copy the mmssms.db file to the computer. At this point, the SMS database file is obtained;

Description:

1, different mobile phones, or different models of the same brand, may have different storage locations in the SMS database, but the above process is the same, all files are found on the mobile phone and copied to the computer. The above process is for reference only, and specific mobile phones should be searched according to the situation.

2. From the installation of RE Manager to the operation, and then to the permission to operate mobile phone files, these operating mobile phones may prompt "permission not obtained" and other error prompts, especially Samsung, Xiaomi and some domestic high-end models, which have various protection measures for mobile phone data and need to obtain the ROOT permission of the mobile phone first, which is also a very headache. Although there are many softwares that can be easily obtained now, they are actually operated.

3. If the file can't be copied all the time during the operation, or the file can't be found, Datang Data Recovery can help to copy the file remotely. Simply put, the user connects the mobile phone to the computer with a data cable, and then we can remotely operate the mobile phone through QQ.

4. How many short messages can be recovered in the end depends on the timeliness of copying files. So after deleting the message, it is best to save the file in time.
