1. Install Mi Home in Developer Mode (China Mainland account required).
2. Connect the gateway to the computer by USB (use OTG-cable).
3. In the app, select Add Device Manual → Gateway 2 → Update Firmware.
4. Download the official firmware from the Mi Home website and follow the wizard's instructions.

What do I do after the dump?

After the successful reset, the Xiaomi Gateway 2 will return to factory settings, and then it needs to be re-introduced and configured.

1. Appendix to the annex: 📱 Open Mi Home or Aqara Home → Add the device. 🔍 Select the Gateway (Gateway) → Xiaomi Gateway 2. 🔄 Follow the instructions on the screen (bring the phone to the gateway for Bluetooth pairing).

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when resetting Xiaomi Gateway 2, and here are the most common ones and ways to prevent them:

• ❌ Reset during firmware update: If you interrupt the update process, the gateway can turn into a brick. Always wait for the update installation to be completed (the indicator is on green).
• ❌ 5GHz Wi-Fi usage: Gateway only works with 2.4GHz networks. If the router does not support frequency sharing, temporarily disable 5GHz in settings.
• ❌ Reset button incorrectly held: If you release the button too early (before the yellow blink), the reset will not be performed. Hold it for at least 10 seconds after the power is connected.
• ❌ Attempted reset via third-party firmware: Some users try to flash the gateway with custom firmware (for example, to integrate with Home Assistant).This can lead to loss of warranty and unstable work.

⚠️ Warning: If the gateway flashes red continuously after reset, it indicates a critical firmware error, in which case only flashing through Mi Home Developer Mode or contacting a service center will help.

Before reset, be sure to check the lock firmware version in the app. If it is older than 1.4.0, after reset, you may have problems adding devices - update the firmware in advance!
