After updating the firmware, your Xiaomi Mi Robot, Viomi or Dreame started to glittle, misorientate in space or completely stopped responding to commands? You are not alone: many users face bugs in new versions of software that worsen the operation of the device. Firmware rollback is a radical but sometimes necessary step to return the vacuum cleaner to its former stability.
In this article, we will discuss all the official and informal ways of rolling back firmware on Xiaomi robot vacuum cleaners, including models with support for Mi Home, Xiaomi Home and alternative firmware. You will learn how to prepare a device, where to find old versions of software, and what pitfalls can occur when downgrade. Importantly, the process requires accuracy - wrong actions can turn a vacuum cleaner into a brick.
Before you start, check if the firmware is really the problem. Sometimes the crashes cause:
- π Battery discharge (less than 20% charge)
- πΆ Poor connection to Wi-Fi or Xiaomi servers
- π§Ή Contaminated sensors or bumpers
- π Conflict with third-party applications (e.g. Home Assistant)
If you've ruled out those factors, we'll start with the recoil.
1. Preparation for the rollback of the firmware: what to do before the start
Firmware rollback is not just clicking on the "Return the old version" button, it's a process that can erase all vacuum cleaner settings, including room maps, cleaning schedules and custom settings.
Step 1: Back up your settings (if possible) in the Mi Home or Xiaomi Home app:
- Open the vacuum cleaner card.
- Go to Settings. β Other settings β Backup.
- Save the file to the cloud or locally.
Step 2. Check the current firmware version. This will help you choose the right version to roll back.

Step 4: Prepare the tools:
- π₯οΈ Computer with Windows/macOS/Linux (for ADB-method)
- π USB-Type-C or Micro-USB cable (depending on model)
- π‘ Stable Internet connection (if you download firmware)
- π οΈ Programs: Mi Home (last version), ADB Tools, Python (for scripts)

β οΈ Note: If your vacuum cleaner was purchased in China (version) CN), A rollback to global firmware (Global) can block some features, such as a voice assistant in Chinese. Check the region of the device in Settings β About the device β Region.
2.Official method: rollback via Mi Home (if available)
The safest method is to use the built-in rollback feature in the Mi Home app, which unfortunately isn't available for all models and not all firmware versions.
Instructions:
- Open Mi Home and select your vacuum cleaner.
- Go to Settings β About the device β Update firmware.
- If the βReturn the previous versionβ section is available, click on it.
- Confirm the action and wait until the completion (usually 10β30 minutes).
If you don't have an option, Xiaomi has blocked the rollback for your model, and you'll have to use alternative methods.
| Model vacuum cleaner | Does the official rollback support | Alternative methods |
|---|---|---|
| Xiaomi Mi Robot Vacuum-Mop 2 Pro | β No. | ADB, hand-stitch |
| Viomi V3 | β Yes (only within 14 days of the update) | β |
| Dreame D9 | β No. | Only through the service center. |
| Xiaomi Mi Robot 1S | β Yes (through hidden menu) | ADB, if the menu is not available |
If the official method did not work, we move on to more complex methods.

3. Pushback through ADB: for advanced users
The method using Android Debug Bridge (ADB) Suitable for Android-based models (e.g. Viomi) V2 Pro or Dreame Z10 Pro) It requires connecting the vacuum cleaner to the computer and executing commands in the terminal.
Step 1. Enable the developer mode on the vacuum cleaner:
- In the Mi Home app, go to Settings β About the device.
- Click 7 times on the firmware version line before the message βYou became a developerβ appears.
- Return to the main settings β a new section βFor developersβ will appear.
- Activate "Debugging by" USBΒ».
Step 2. Connect the vacuum cleaner to the PC:
- π Use the original cable (not all) USB-cables support data transmission).
- π₯οΈ Drivers must be installed on the computer ADB (You can download from the official Android website).
Step 3: Follow the commands for rollback:
adb devices # Checking the connection
adb shell # Entrance to the shell
su # Getting root rights (if required)
pm list packages | grep mihome # Checking installed packagesYou need firmware in.zip or.img to roll back, and you can find it on forums like this. 4PDA Or Xiaomi Community. After you upload the file, do it:
adb sideload firmware.zip # Download firmwareβ οΈ Note: Some models (e.g. Xiaomi Mi Robot Vacuum-Mop P) are blocked ADB If the process is interrupted, the vacuum cleaner can stop turning on, in which case only the flashing through the test points (requires rations) will help).
What if the ADB canβt see the device?
4. Manual firmware via Recovery Mode (for experienced)
If ADB If it didn't work or your model didn't support it, you can try to clean the vacuum cleaner through Recovery. MTK-chips (e.g. Viomi) SE Or the old Mi Robot).
Step 1. Download the firmware:
- π Look for files with the.bin or.img extension for your model.
- π‘οΈ Check files for viruses (it is better to download from trusted sources, for example, Xiaomi Community).
- π Make sure the firmware version is older than the current one (check in Settings). β About the device).
Step 2. Transfer the vacuum cleaner to Recovery Mode:
- Turn off the vacuum cleaner (hold the power button for 5 seconds).
- Press the power button. + Home button (if any) for 10-15 seconds.
- Let go when the blue or orange light lights up.
Step 3. Flow through USB:
- π₯οΈ Connect the vacuum cleaner to the PC.
- π Place the firmware file in the root of the C disk: and rename it to firmware.bin.
- π§ Use the utility. SP Flash Tool (for Flash Tool) MTK) or Fastboot (for Qualcomm) for downloading firmware.
Critical information: On models with a Rockchip chip (e.g. Dreame) D10 Plus) hand firmware can block the bootloader, in which case you will need a special dongle to unlock, which is sold only from official Xiaomi dealers.

Before you run through Recovery, take a photo or screenshot of the current version of the software. If something goes wrong, it will help the specialists of the service center to diagnose the problem faster.
5. Risks of firmware rollback: what could go wrong
Firmware rollback is always a lottery, and even if you follow the instructions, there are risks you should know about beforehand:
- π¨ Locking the device ("brick") - the vacuum cleaner stops turning on or is loaded only before the logo.
- π Loss of account binding β after rollback, the vacuum cleaner may require re-addition to Mi Home.
- πΊοΈ Resetting of room maps β all saved maps and cleaning areas will be removed.
- π΅ Sensor failure β after a downgrade, lidar, gyroscope or collision sensors may not work properly.
- π Accelerated battery discharge β old firmware is sometimes worse optimized for battery.
The most common mistakes in the rollback:
| Mistake. | Reason. | Decision |
|---|---|---|
| Error: Device not found | ADB doesn't see vacuum cleaner | Check the cable, drivers, turn on debugging USB |
| The vacuum cleaner vibrates and does not turn on | Incorrect firmware or interrupted process | Re-scan through Recovery or contact the service |
| Signature verification failed | The firmware is not signed for your model | Look for a firmware with the right signature |
| Continuous reset | Conflict of bootloader and software versions | You need to flash the full package (including the bootloader). |
If the vacuum cleaner doesn't work after rolling back, don't try to re-stitch it, which can make the problem worse. You should contact the service center with the version of the firmware you tried to install.

90% of the problems with firmware rollbacks are due to software and bootloader versions being incompatible, and always make sure that the firmware is designed for your model and region.
6. Alternative solutions: if rollback is not possible
What if you can't roll back the firmware or you're afraid of the risks? There are several alternatives:
1.Reset to factory settings
Sometimes firmware bugs are related to settings, not the software itself.
- At Mi Home, go to Settings β Other settings β Resetting settings.
- Confirm the action (the vacuum cleaner will restart).
- Reconfigure it as if it were after purchase.
2. Use of alternative firmware
For some models (such as the Xiaomi Mi Robot Vacuum 1), custom firmware like Valetudo or OpenMiRobot is available, which gives you more control over the device, but:
- π Requires unlocking of the loader.
- π« They may lose their guarantees.
- π οΈ You need skills to work with Linux/ADB.
3. Contact the service center
If the vacuum cleaner is guaranteed, it is better not to risk it and take it to the official Xiaomi service.
- π Official Xiaomi website (Service Centers sectionΒ»).
- π Partner shops (for example, Svyaznoy, M. Video).
- π§ Unofficial workshops (check reviews!).
Selling/replacing the device
If the vacuum cleaner became completely inoperable after a failed rollback, and repairs are too expensive, consider the options:
- π° Sale for parts (on Avito or Yule often buy faulty vacuum cleaners for repairs).
- β»οΈ Exchange under the trade-in program (in some stores they give a discount on a new vacuum cleaner when passing the old one).
7.How to avoid firmware problems in the future
So that you do not have to roll back the firmware again, follow these tips:
- π Check out the reviews about the new firmware on the forums (4PDA, Reddit, Xiaomi Community before the update.
- β³ Wait 1-2 weeks after the update is released β critical bugs are usually detected during this time.
- π‘ Update over Wi-Fi, not mobile internet (download interruption can ruin firmware).
- π Charge the vacuum cleaner to 100% before upgrading.
- π± Use the latest version of Mi Home (older versions of the app may not install firmware correctly).
