My Aha Halo has been stuck on the “Firmware update” screen for 4 days.

I purchased the Halo after July 25, 2025.

I am using the original USB cable supplied by Aha. Windows detects the device correctly as:

**Silicon Labs CP210x USB to UART Bridge (COM3)**

The Aha software previously displayed:

**Connection to halo was lost**  
**Exception RuntimeException -1000**  
**Timeout 2**

I have already attempted the recovery procedure, but the Halo remains stuck on the Firmware Update screen.

Please send me the **latest Windows firmware recovery/flash tool and the exact recovery instructions for the post-July 25, 2025 Halo**.

This error can happen if the firmware update was interrupted. If your Aha Halo screen is showing **“Firmware Update,”** please keep the device connected to your Windows computer and ignore the connection/error message in the software.

Click the **Firmware Update** button in the Aha software several times until the update progress begins.

You don’t need the Windows flash tool. There is no Firmware upgrade button, so instead once you connected halo (and the software cannot find it) use the menu command “Check for Firmware update”. No need to select it several times. You will be asked to select the serial port halo is connected to, and the firmware upgrade will take place.

If halo’s display is blank, hold the left and up buttons while you plug the USB cable into halo.

Can you replicate how you landed in this stuck upgrade? It‘s a critical task which can fail at any short unintentional disconnection. If you did not do so, can you send the respective log to support?
