Accidental deletion of important correspondence on WhatsApp on a smartphone Samsung is a situation familiar to many users. The question arises especially acutely when it is necessary to return data not for yesterday, but for an entire month. Standard recovery methods are often limited to the last 24 hours, but on the platform Android there are deeper mechanisms for saving data that allow you to roll back the state of the messenger.

Restoring an archive of messages over a long period requires an understanding of how exactly the system One UI manages database files. Unlike iOS, where everything is tied to the cloud, Android creates local copies that are stored in the deviceโ€™s memory. If you did not forcefully clear the cache or do a full reset, the chances of returning dialogs within 30 days remain high.

In this article we will analyze in detail algorithms for extracting data from hidden system folders, working with encrypted database files and using specialized software. You will learn how to manipulate files msgstore.db.crypt14 and why the date the file was created is more important than the date the message was deleted.

Principles of backup in WhatsApp on Android

Mechanism for saving chat history on WhatsApp devices Samsung works on the principle of file rotation. Every day at a certain time (usually 2:00 am), the application creates a new copy of the database and stores it in a special directory. In this case, old files are not deleted instantly, but are moved to the archive, saved for seven days by default.

However, to restore data for a month, the standard weekly cycle is not enough. This is where the file system feature Android and the ability to manually manage backups come into play. If the user previously manually copied the folder Databases to a computer or cloud drive, the recovery process is simplified to replacing a single file.

It is important to understand the difference between local backup and synchronization via Google Drive. A cloud backup is usually overwritten with each update, so it is impossible to roll back a month through the settings of the application itself - you will only restore what was last uploaded to the cloud. Local files live their own lives and do not depend on cloud settings unless a complete system reinstallation has been performed.

โš ๏ธ Attention: The recovery process by replacing database files leads to the loss of all messages received after the date of creation of the selected backup. Be prepared for the fact that correspondence over the last few days will be lost.

The encryption system also plays a key role. Files have an extension of the form .crypt12, .crypt14 or .crypt15, where the numbers indicate the version of the encryption protocol. The decryption key is tied to your account and stored in the system partition, which allows the application to automatically recognize the file when restoring, even if it was created a month ago.

Searching and preparing local backup files

The first step to return data for a month is to search for saved files in the phone memory. On modern versions Android access to system folders is limited, but the file manager My Files, preinstalled on Samsung, allows you to navigate to the desired directory. The path may differ depending on the version of the operating system.

On devices with Android 11 and newer, the path to the database has changed for security reasons. Now the files are located at Android/media/com.whatsapp/WhatsApp/Databases. On older firmware, the path is classic: WhatsApp/Databases at the root of the internal memory. You need to find files with names like msgstore-2023-10-25.1.db.crypt14.

If there are no files in this folder with dates that are a month old, this does not always mean data loss. Sometimes users accidentally move folders or files are saved to a memory card microSD. Check the presence of the directory WhatsApp on the external drive, if it is used in your device Samsung.

  • ๐Ÿ“‚ Open the "My Files" application and go to the "Internal Memory" section.
  • ๐Ÿ” Find the folder Android, then media, further com.whatsapp.
  • ๐Ÿ’พ Go to the folder Databases and sort the files by date of modification.
  • ๐Ÿ“… Look for files with the name msgstore and the date corresponding to the month ago.

Pay attention to the file size. The database for a month of active correspondence can occupy from 50 MB to several gigabytes. If you find a file of a suspiciously small size (several kilobytes), most likely it is an empty template or a damaged fragment that is not suitable for recovery.

๐Ÿ’ก

Before any manipulations, copy the entire Databases folder to your computer or cloud storage. This will create a rollback point if the recovery process does not go according to plan.

Method of manually replacing database files

The most effective way to return correspondence for a specific date is to manually replace the current database file with an archived one. This method requires care, as an error in the file name will cause WhatsApp It simply wonโ€™t see the backup copy and will offer to restore data from Google Drive, which is not suitable for us.

First, you need to rename the current active database file. Find the file msgstore.db.cryptXX (without a date in the name) and change its name by adding any word, for example, msgstore.db.cryptXX.current. This action will save your current (empty or incomplete) database in case it is needed in the future.

Then select the file with the desired date (one month ago) that you found in the previous section. Rename it by removing the date from the name so that it becomes strictly msgstore.db.cryptXX. It is important to keep the file extension unchanged. If you have multiple files with different encryption versions (for example, crypt12 and crypt14), choose the one whose version matches the currently installed version of the application, or the most recent one available.

Source name: msgstore-2023-09-15.1.db.crypt14

Target name: msgstore.db.crypt14

After renaming, you need to clear the application data WhatsApp. Go to Settings โ†’ Applications โ†’ WhatsApp โ†’ Storage and press the button Clear data. Don't confuse this with "Clear cache", it won't work. This action will delete the current application setting, but will not affect the database file you prepared.

Using third-party software for deep analysis

If local files have been deleted or damaged, specialized utilities for data recovery come to the rescue. apps like Dr.Fone, Tenorshare UltData or Expert Android are capable of scanning the device's memory for the presence of deleted sectors where database fragments could be stored.

The effectiveness of such apps directly depends on the presence of root access on your device Samsung. Without superuser rights, access to system partitions where deleted data is stored is closed, and apps will only be able to find what is visible in a regular file manager. Obtaining root access on modern Samsung is difficult and can lead to protection being triggered. Knox.

The process of working with such software is usually standardized: connecting the phone via USB, enabling USB debugging in the developer menu and starting scanning. The app tries to collect fragmented files .db and restore their structure. However, it is worth understanding that no one can guarantee recovery within a month, especially if the phoneโ€™s memory was actively used and old data was overwritten by new ones.

โš ๏ธ Attention: Using data recovery apps with root access may void the warranty on your Samsung device due to Knox security flags being triggered. Use this method only as a last resort.

Some utilities offer a preview function before recovery. This is a useful option that allows you to see whether the found fragment actually contains the necessary correspondence before paying for the full version of the app. Free versions often show only the first few messages from a found chat.

What is Download Mode recovery?

This is a special mode in Samsung devices used for flashing firmware. Some advanced data recovery methods require entering this mode to directly access memory partitions, but this is extremely risky for the average user.

Recovery via Google Drive: limitations and nuances

Many users hope for Google Drive as a panacea, but in the context of recovering data for a month, this method has strict limitations. WhatsApp stores only one latest backup copy in the cloud. As soon as a new backup is created (for example, tonight), the one from yesterday in the cloud is replaced forever.

The only chance to use the cloud to roll back a month is if you have disabled automatic updating of backups for more than a month, and the old version is stuck in the cloud. In this case, when you reinstall the application, you can choose to restore from Google Drive, and the system will pull up exactly the file that is located there.

You can check the date and size of the backup in the cloud through the settings itself Google Drive. Go to the menu, select Backup copies and find the entry WhatsApp. The exact date the file was created will be indicated there. If the date corresponds to a month ago, you're in luck. If today's date is there, this method is useless for your purpose.

It is worth noting that restoring from the cloud requires the same account Google and the same phone number that were used to create the copy. Changing the number or account will make the backup file unavailable for recovery, since the encryption keys will be incompatible.

๐Ÿ’ก

Google Drive stores only one version of the backup. If automatic copying is enabled, it is impossible to restore data older than the last synchronization via the cloud.

Frequent errors and problems during recovery

Even if all instructions are followed, users often encounter errors. The most common problem is a "Backup file not found" or "Invalid file" message. This almost always means an error in the file name or a mismatch in the encryption version.

Another common situation is an endless recovery process that freezes at 99%. This may indicate damage to the database file itself or insufficient free memory on the device to unpack the archive. Make sure that your Samsung has at least 2-3 GB of free space before starting the procedure.

It is also possible that messages have been restored, but media files (photos, videos) are missing. This is normal since the database only stores text and media links. The image files themselves are stored in the folder Media and are not restored along with the database msgstoreif they were deleted from the gallery. You will have to look for them separately in the folder Sent or Private.

  • โŒ Crypt version error: You are trying to open a crypt12 file on a version of WhatsApp that requires crypt14.
  • โŒ Lack of space: The process of unpacking the database requires temporary space equal to twice the file size.
  • โŒ Antivirus blocking: Samsung security software can block the replacement of messenger system files.

If after all the manipulations the application crashes on startup, try uninstalling WhatsApp completely, reboot the phone, rename the database file again and install the messenger again. A clean installation often resolves cached data conflicts.

Is it possible to restore correspondence if the phone has been reset to factory settings?

If a full Factory Reset was performed without first copying the Databases folder to an external drive or PC, restoring local backups is almost impossible. The data in the internal memory is permanently erased. There is a chance only if the backup managed to go to Google Drive before the reset.

Does the Samsung model (S21, S23, A54) affect the recovery process?

The phone model does not affect the logic of WhatsApp, but it does affect the path to the files. On new models with Android 13/14, the path is deeper (Android/media), on older models there is direct access from the root. Also, new models are stricter about access rights, requiring additional permissions for file managers.

What to do if the msgstore.db.crypt14 file weighs 0 KB?

A file of 0 KB is empty and contains no data. This means that an error occurred when creating the backup or the memory was full. It is impossible to restore correspondence from such a file; you need to look for another file with a date close to the desired one, but with a normal size.

Is it safe to use modified versions of WhatsApp for recovery?

No, using unofficial clients (GBWhatsApp, WhatsApp Plus) to restore official backups can lead to complete loss of data and blocking of the account by the WhatsApp servers. Use only the official application from Google Play.

Is it possible to recover messages from a specific contact, and not the entire correspondence?

You cannot select individual chats for recovery using standard WhatsApp tools. The process restores the entire database. To get correspondence with only one person, you need to restore a full backup, export the desired chat to a text file, and then clear the data again and restore a more recent version without this chat.
