Have Ax3000 Deco x60 (v3) (US) with stock firmware version 

1.0.7 Build 20210915 Rel. 62826  

The app and web ui prompts an update to  

1.2.5 Build 20240106 Rel. 2319  

The update process goes through but the firmware remains at the stock 1.0.7 via both the app method and the WebUi.  

Have tried flashing the same version through the webUi with the zip file but the results are the same.   

The device is super unstable so I can try other firmware versions but am afraid of bricking or voiding the warrenty on a new unit.  

Any help would be appreciated.
