Where and how to reflash the robot vacuum cleaner Xiaomi: official and alternative methods

Why Xiaomi’s Robot Vacuum Robot Might Be Needed

Xiaomi’s robot vacuum cleaners (including models under the Dreame, Viomi and Mijia brands) receive firmware updates regularly, but they don’t always come automatically. Users face situations where forced firmware is required: after a software failure, to unlock regional restrictions or install custom firmware with advanced features. For example, owners of Xiaomi Mi Robot Vacuum-Mop 2 Pro often update the firmware to activate Alice’s Yandex support or fix navigation bugs.

However, not everyone knows that firmware through unofficial sources can deprive warranties and even “brick” the device. In this article, we will analyze all available methods – from official (via the Mi Home app) to alternative (via the Mi Home app) ADB or TTL-If your vacuum cleaner is stuck on the logo, does not respond to commands or requires an update to work with a new hub, you will find a solution here.

The safest method is to use proprietary apps. Xiaomi provides two official tools for updating:

• 📱 Mi Home is a universal application for all ecosystem devices (suitable for most models, including Mi Robot Vacuum). 1S dreame D9).
• 🤖 Mi Robot App – specialized software for robot vacuum cleaners (recommended for new models, for example, Xiaomi Robot Vacuum-Mop 2 Ultra).

To update the firmware through the application:

1. Connect the vacuum cleaner to the same Wi-Fi network as the smartphone.
2. Open Mi Home, select your device → Settings (⚙) → Firmware update.
3. If the update is available, click Download and Install. The process will take 10 to 30 minutes (the vacuum cleaner will restart automatically).

⚠️ Warning: If the vacuum cleaner is disconnected from the network during the update via the application, try reconnecting it manually. If the device is stuck during the Prepare for Update stage for more than 20 minutes, forcefully restart it by holding the power button for 10 seconds.

If your vacuum cleaner doesn’t find updates in Mi Home, try changing your account region to Mainland China in your profile settings.

USB Firmware: Step-by-step instructions for experienced users

If the official update is not available or you need to roll back on the previous version, you can sew the vacuum cleaner through the USB-This method is suitable for models with a Micro-USB or Type-C connector (for example, Dreame). D9, Viomi V3). You'll need it:

• 🖥️ Computer with Windows/Linux;
• 🔌 Cable USB (original, with data transmission support);
• 📁 Firmware in.pkg or.bin format (download only from trusted sources, such as forums) MIUI SU);
• 🛠️ MiRobotTool or DreameTool (for unpacking and installation).

Algorithm of action:

1. Download the firmware for your model (make sure the version matches the current one!). For example, for Dreame D9, look for files marked dreame.vacuum.p2016.
2. Unpack the archive with firmware. Inside should be an app.bin file or firmware.pkg.
3. Connect the vacuum cleaner to the PC turned off (hold the power button for 5 seconds to completely turn off).
4. Press the Home button (or Spot Clean for some models) and, without letting it go, plug it in. USB-The vacuum cleaner should be defined as a removable disc.
5. Copy the firmware file into the root directory of the vacuum cleaner’s “disk” (not into folders!).
6. Turn off the cable, turn on the vacuum cleaner - the update will begin automatically (the indicator will flash orange).

Download firmware for exact model | Check file integrity (MD5-hash) | Disable antivirus (can block utilities) | Charge vacuum cleaner by at least 50% | Prepare a screwdriver (to access the port, if necessary)

⚠️ Attention: If the vacuum cleaner emits an error signal after the firmware is run (3 short squeaks), then the firmware file is not suitable. Do not try to flash again, this can block the loader. TTL-port (soldling iron required).

Firmware via TTL (UART): to restore "brick" devices

If the vacuum cleaner does not turn on, hovers on the logo or gives an error Error 12 (damaged loader), the only way to bring it back to life is through the firmware. TTL-This method requires disassembling the device and working with a soldering iron, so it is only suitable for experienced users.

You'll need:

• 🔧 A soldering iron with a thin sting (power up to 30 W);
• 🕹️ USB-to-TTL adapter (e.g., USB-to-TTL adapter, CP2102 or CH340);
• 🖥️ Putty or Screen (for the purposes of Linux/Mac);
• 📁 Firmware in.bin format and utility esptool.py (for chips) ESP32).

Procedure:

1. Disassemble the vacuum cleaner, find the control board. Look for 4 contacts with the tags: GND, TX, RX, 3.3V (usually located next to the main chip).
2. Salt the wires off. TTL-adapter: TTL GND → GND board-board TTL TX → RX board-board TTL RX → TX board-board TTL 3.3V → 3.3V on board (not necessarily if the food comes from a vacuum cleaner)
3. Connect the adapter to the PC, open Putty at a speed of 115200 baht.
4. Turn on the vacuum cleaner (hold the power button). The terminal should show the words Waiting for command.
5. Download the firmware through the command: esptool.py --port COM3 write_flash 0x0 firmware.bin (substitute COM3 to your port and firmware.bin filename).

💡

Firmware through TTL is the only way to restore the vacuum cleaner after a failed USB update or software failure. However, an incorrect connection can damage the board. If you are not sure about your skills, contact the service center.

Alternative methods: ADB and custom firmware

For advanced users who want to unlock hidden features (such as manual fan speed control or disabling regional restrictions), custom firmware exists.

• 🌍 Valetudo – open firmware for Rockrobo-based robot vacuum cleaners (suitable for Mi Robot Vacuum) 1/1S). Allows you to manage your device without the cloud Xiaomi.
• 🔓 DustBuilder – a tool for modifying official firmware (add support for Home Assistant, change voice packets).

2. Connect to the vacuum cleaner via Wi-Fi (it creates its own access point rockrobo-XXXX).
3. Use the command to download firmware: adb push firmware.zip /sdcard/ adb shell su -c "unzip /sdcard/firmware.zip -d / & sync & && reboot"

⚠️ Attention: Castom firmware violates warranty conditions and may contain vulnerabilities. For example, in 2023, Valetudo firmware was discovered to allow remote control of the vacuum cleaner over the local network.
