Hi, 
What's the phenomenon you experienced with Deco M4 before trying the HTTP Recovery Mode? For example, do you have internet when connecting to Deco M4? What's the LED status on Deco?
Best Regards

@Solla-topee Failed everytime after 5% and LED lights are yellow, red, green, blue and then again red and yellow and keep stuck on yellow. My Deco is dead after voltage fluctuation i think.

Hi, 
If your Deco M4 has a solid yellow LED and it does not respond to the factory reset or firmware recovery. You can contact your retailer or the local support team to check whether the Deco is under warranty.
Best Regards

  @Solla-topee I have bought my Deco system in 2023 and i dont think that they are still in warranty. Today i have noticed when i connect ethernet cable with PC and plugged power cable so the Deco goes into Recovery Mode automatically and dont need to press and hold reset button and when ethernet cable is disconnected and when i plugged power cable so the Deco stuck on yellow light. I dont know why Deco goes into Recovery Mode automatically when ethernet cable is connected with PC.

Hi, 
I have no more suggestions on this case. If the Deco is behaving abnormally and is not under warranty, you may purchase a new router or Deco if needed.
Best Regards
