Accidental deletion of important messages is a stressful situation faced by many users of Xiaomi, Redmi and Poco smartphones. Often we clear memory or delete dialogues mechanically without thinking about the consequences, until there is an urgent need to find a specific confirmation code or important correspondence. Fortunately, the Android operating system and the MIUI shell (or HyperOS) provide several data protection mechanisms that can save the situation even after a while.
Before you panic and start a mess, you need to be clear: recovery success depends on whether you have synced or backed up before you lose information. If you've used cloud services, you're about a hundred percent likely to return text messages. If you haven't done automatic backups, it's a little bit more complicated, but there are still a number of software methods that you can try.
In this article, we will take a closer look at all the ways to recover lost data, from the Xiaomi ecosystem’s regular tools to the dedicated deep memory scanning software, and it’s important to act consistently and keep steps in place, as some methods can overwrite memory sectors, making recovery impossible.
Using the Mi Cloud Cloud Service to Recover
The most effective and native way for Xiaomi smartphone owners is to use the built-in Mi Cloud storage.This service is integrated into the system by default and often automatically synchronizes key data, including contacts, notes and messages, unless the user has disabled this feature manually. To check for a backup, you need to log into your account settings through the device menu.
The process of checking and restoring is as follows: first make sure that the smartphone is connected to a stable Wi-Fi network, as the amount of data can be significant. Then go to the settings section associated with the Mi Account and find the cloud control point, and here you can see a list of all the data categories that are subject to synchronization.
- 📱 Open Settings and click on the top plaque with your Mi Account.
- ☁️ Select Cloud or Mi Cloud from the menu that opens.
- 💬 Find the Messages section and check the date of the last synchronization.
- 🔄 If a copy exists, press the restore button or enable synchronization so that the data is automatically downloaded.
It is important to note that recovery from Mi Cloud can take time, especially if there are many messages accumulated. During the download process, it is not recommended to interrupt the connection or close the settings application. If the date of the last sync coincides with the period before deletion, then your messages will be returned to the standard Messages application without losing the dialog structure.

Enable automatic message sync in Mi Cloud right now so you don’t have to face any future data loss issues.
Recover Messages via Google Drive and Google One
An alternative and often more versatile method is to use the Google ecosystem: Virtually every Android smartphone offers the user to back up data on Google Drive. Unlike proprietary solutions from manufacturers, this method works equally well on any device and often persists even when changing the phone model.
The mechanism of Google One (backup service) is to periodically save a cast of data, including SMS and MMS. However, there is a caveat: recovery usually occurs when the device is initially set up or after a complete reset to factory settings. If you just deleted the message in the working system, simply turning on sync may not return the remote, but will restore the state of the system at the time of the last backup, subject to reset.
⚠️ Warning: Recovering from a full copy of Google Drive often requires a complete phone reset.Make sure you have up-to-date copies of other important files so you don't lose data created after the date of the last backup.
To check for a backup, do the following: Go to Google's settings on your device, select the backup section, which will show the size of the space you occupied and the date of the last successful save, and if the date is current, you can initiate the recovery process.

Software for data recovery from PC
When cloud services have failed or have not been set up, PC software comes to the rescue that can perform deep scans of a smartphone’s internal memory. Utilities like Dr.Fone, Tenorshare UltData, or FonePaw use algorithms to find “remote” but not yet overwritten memory sectors, and the effectiveness of these methods depends on the time elapsed since deletion.
The principle of operation of such software is to connect the phone to the computer through USB-cable and granting the application extended access rights. Often you need to activate debugging mode USB (USB Debugging) in the developer menu. Once connected, the program analyzes the file system and tries to reconstruct the remote database records. SMS.
The scanning process can take anywhere from 10 minutes to an hour depending on the amount of memory, and once the analysis is complete, the program will show a list of found messages that can be selected and exported to the computer in a readable format.
| Programme | Type of scan | The Root's Necessity | Cost |
|---|---|---|---|
| Dr.Fone | Deep. | Often required | Paid |
| Tenorshare UltData | Standard/Deep | Not always. | Paid |
| Android Data Recovery | Basic | Required. | Free-of-charge |
Why do some programs require a Root right?
Analysis of local copies and folders of the basket
MIUI shell and modern versions of Android introduce security features that prevent instant data loss. In some firmware versions, deleted messages do not disappear forever immediately, but move to a hidden Recycle Bin folder or archive where they are stored for 30 days, similar to the work of the basket in the operating systems for PCs.
Also, check for local backups that the system could have created automatically before updating or on schedule, which are usually stored in hidden internal memory directories or on a computer. SD-The path to them often looks like MIUI/backup/AllBackup, Where to find archives with.bak extension.
If you find one, you can try to deploy it through the built-in system recovery menu, and you can go to advanced settings, select Recover and Reset, and point the way to the archive you found, and not only return the messages, but also the other settings that were at the time of the backup.
- 🔍 Check the Messages app for the Archive or Cart tab».
- 📂 Use the file manager to search for files with the.bak extension in the folder MIUI.
- ⚙️ Go to Settings. → The phone. → Click on the version several times MIUI, Open the developer menu if you need to access hidden features.
💡
Local backups are automatically created by the system, but their availability depends on the phone model and firmware version. Always check for the backup folder in the file manager.
Specifics of working with the database mmssms.db
For advanced users familiar with the Android file system, the question of working directly with the message database is relevant. All SMS and MMS on the device are stored in the mmssms.db file located along the path /data/data/com.android.providers.telephony/databases/. Access to this directory is possible only with superuser rights (Root).
If you have Root rights, you can use file managers with access to system partitions (such as Root Explorer or MT Manager). By copying a database file to a computer, you can open it with SQLite editors. In such programs, you can often see deleted entries marked as free space and try to extract them.
However, this method is extremely risky for beginners: Incorrect editing of system files can cause the Messages app to stop running or the phone to go into a cyclical reboot. So make sure to create a full copy of the data partition before any manipulation of the database.
⚠️ Note: Editing the mmssms.db file manually without knowledge of the SQLite structure can permanently damage the message database.
Prevention of data loss and setting up autosave
To avoid future recovery problems, it is advisable to set up automatic backups. The best strategy is a combined approach: using the manufacturer's cloud services for quick synchronization and periodically creating full copies to a computer or external drive.
The frequency of copy creation depends on the intensity of smartphone use. Daily backup of important dialogues will be optimal for active users. Modern SMS applications, such as SMS Backup & Restore, allow you to flexibly adjust the schedule and send copies to several places at once: on Google Drive, in Dropbox or by email.
You should not ignore the system updates, as new versions of MIUI and HyperOS often improve data algorithms and new security features. Watch for notifications about the release of new versions of the software and install them, saving important data beforehand.
