Hey everyone, I need some help with my Xiaomi Robot Vacuum X20 Max.
Out of nowhere, it lost connection with the Xiaomi Home app and won't reconnect. Everything else on the robot is working 100%. It sweeps, mops, docks, charges, and drains water normally via the physical buttons.
The issue:
* When holding Power + Home to reset the network, the robot voice says "Waiting for network configuration", but right after that, the buttons start flashing orange.
* The blue Wi-Fi LED under the lid never turns on, it stays completely dark.
* The robot does not broadcast its temporary Wi-Fi SSID (xiaomi-...), and the app cannot discover it via Bluetooth, manual search, or QR code.
What I have already tested:
* Charged battery to 100% on the dock.
* Hard reset via the pinhole button under the lid.
* Disconnected the main battery plug from the motherboard for about 30 minutes to drain residual power for a cold boot.
Still nothing. The Wi-Fi LED remains completely dead and no signal is emitted.
Has anyone experienced this before? Any troubleshooting tips or schematic pointers would be greatly appreciated!
Thanks!
