How to completely clean another Xiaomi device: from smartphone to router

When it comes to cleaning Xiaomi devices, most users think only of smartphones. But the brand ecosystem is much broader: Mi Band smartwatches, Smart Band fitness bracelets, Mi Router routers, Mi TVs, Redmi Buds headphones and even Mijia electric scooters. Each of these devices accumulates data, cache, personal information β€” and sooner or later requires complete cleaning. The reasons can be different from preparation for sale to eliminating system lags.

In this article, we’ll look at all the possible cleanup options for Xiaomi’s different categories, from classic resets to factory settings to hidden commands for power users. You’ll learn how to properly erase data from the Mi Band 8 without losing communication with your phone, why resetting the router through a button doesn’t always work, and what to do if the smartwatches stop syncing after cleaning, and unique methods for proprietary firmware devices (such as the Mi Scooter 4 Pro), which are not described in the official documentation.

1. Xiaomi Smartphone Cleanup: From Redmi to POCO

Smartphones are the most common category of Xiaomi devices, and the cleaning options are the most. The main methods depend on the version of MIUI (relevant to MIUI 14/15) and the processor model (Snapdragon, Mediatek, Google Tensor in POCO F6).

The safest way is to reset your user data, but it saves your system files, if your phone is slowing down or you need to remove any extra files before you sell them.

  • πŸ“± Go to Settings. β†’ The phone. β†’ Resetting settings
  • πŸ”„ Select Reset All Settings (not to be confused with Network Resettings!)
  • πŸ” Enter your Mi Account password if requested
  • ⏳ Wait for the reboot (usually takes a lot of time) 3-7 minute)

If the smartphone does not respond to touch or is locked, you will need a hard reset via Recovery Mode.

  1. Turn off the device.
  2. Press Volume Up + Nutrition (on some models – Volume Down + Nutrition).
  3. In the recovery menu, select Wipe Data (movement – volume buttons, choice – power button).
  4. Confirm the action and wait for the completion.

⚠️ Note: On devices with Snapdragon 8 Gen 2 (such as Xiaomi 14 Ultra), a hard reset can lead to a bootloader lock if previously unlocked OEM Unlock. In this case, you will need to re-unlock through the Mi Unlock Tool.

2.Reset smartwatches and fitness bracelets Mi Band

Xiaomi smartwatches and bracelets (Mi Band 7/8, Smart Band Pro, Watch 2 Pro) are cleaned differently than smartphones. There is no classic β€œrecovery mode”, but there are hidden combinations and bindings to the Mi Fitness app (or Zepp Life for new models).

To reset the Mi Band 8 through the device itself:

  • πŸ•’ On the main screen of the clock, swipe down to the settings menu.
  • πŸ”§ Select the System β†’ Resetting settings.
  • βœ… Confirm the action on the watch screen.

If the watch does not respond to touch, use a hardware reset:

  1. Unplug the strap and find the reset button on the back (a small hole next to the sensors).
  2. Take a paper clip, press and hold the button for 10-15 seconds until vibration appears.
  3. Connect the watch to charging – it will automatically reboot.

3. Cleaning up Mi Router routers: When button reset doesn't work

Xiaomi routers (Mi Router 4A/4C/AX3000/AX6000) are easier to clean than smartphones, but there are pitfalls here. The main problem is incomplete reset when the device returns to factory settings, but saves old data about connected devices.

Classic method:

  • πŸ”Œ Turn the router on.
  • πŸ–±οΈ Find the Reset button on the back (usually recessed in the case).
  • πŸ•’ Press and hold it. 10-15 seconds (before all indicators flash).

telnet 192.168.31.1


login: root




Password: (default: admin or empty)




nvram erase

For models with OpenWRT firmware (such as Mi Router 4A Gigabit Edition), the process is different:

  1. Connect to the router via SSH.
  2. Run the firstboot command.
  3. Confirm the reset and wait for the reset.
What if the router does not distribute the Internet after resetting?
1. Check if DHCP is enabled in settings (192.168.31.1 β†’ Additional β†’ Network β†’ LAN). 2. Update the firmware via Mi WeiFi (Update tab). 3. If the WAN indicator is not on, try another cable or port on the router. 4. The AX6000 may require manual 5GHz channel setup (select 36-48 instead of automatic mode).

4. Formatting Mi TV and Mi Box TVs

Xiaomi TVs (Mi TV A2/A Pro/ES 2023) and media set-top boxes (Mi Box S/4K) are cleared through the Android TV menu, but with nuances. For example, on Mi TV P1, resetting through settings does not delete Netflix and Disney+ license data, which can lead to errors when re-authorizing.

Complete cleaning for Mi TV:

  • πŸ“Ί Go to Settings. β†’ The device β†’ Reset.
  • πŸ”„ Select Erase All Data (not Reset Settings!).
  • πŸ” Enter. PIN-code (default 0000 or 1234).

  1. Turn the console off the power.
  2. Press the OK button on the remote and connect the power.
  3. Hold the 10 seconds button until the recovery menu appears.
  4. Select Wipe data/factory reset.

5. Cleaning up Redmi Buds headphones and sound devices

Xiaomi’s wireless headphones (Redmi Buds 4/5 Pro, FlipBuds Pro) don’t have a classic reset interface, but they can be cleaned of the paired devices and returned to factory settings. This is useful if the headphones aren’t connected to a new phone or one isn’t working.

  2. Press and hold the touchpads on both headphones for 10 seconds.
  3. Wait for the beep and the flashing of the red indicator.
  4. Return the headphones to the case and close the lid for 5 seconds.

For smartphones on Snapdragon:

  • πŸ”§ Unlock the bootloader through the Mi Unlock Tool (requires account binding).
  • πŸ“₯ Install. TWRP Recovery for your model.
  • πŸ—‘οΈ V TWRP Choose the Wipe β†’ Format Data and enter Yes.

FAQ: Answers to Frequent Questions

Can Xiaomi be cleaned up without losing data?
Partly yes. On smartphones, you can manually delete the app cache (Settings β†’ Apps β†’ Clear cache), photos and files. But a full reset always erases user data. Use Mi Cloud or local storage to back up.
Why is the Mi Band not synced to the phone after reset?
This is related to the Bluetooth cache. Solution: Remove the watch from the Bluetooth device list on your phone. Reboot the phone. Re-set the watch through Mi Fitness. If it doesn't work, reset the watch again and when you link, select China region (even if you're not in China).
How to clean Xiaomi if you forget your Mi Account password?
There are two options: Restore your password through the official website (you will need a linked email or phone). If the device is blocked, contact the customer service with a check about the purchase. Unlocking may require a video with a serial number. On Mi Router routers, you can reset your password through the MiWiFi utility (only for models until 2022).
I dropped the Mi TV and the remote doesn't work.
The problem is typical for the Mi TV 4S/5X. Solutions: Use the remote from another Xiaomi TV (they are interchangeable). Connect the keyboard or mouse over USB and set up the new remote via Settings β†’ Remote DU. Reset the remote: remove the batteries, press any button 10 times, then insert the batteries back.
Can I clean up Xiaomi Scooter before selling?
Yes, but it's different. For the Mi Electric Scooter 4 Pro: Turn off the scooter. Press the power button and the brake button for 10 seconds. Wait for the double beep, that means reset. Once reset, the scooter will lose its binding to the Mi Home app, and the new owner will be able to reconnect it.
