Can't update Razer Blade 14 2025 to latest July BIOS

Hello Team

 

I have updated my Razer Blade 14 2025 laptop’s MCU and EC to latest July 2026 versions. When I run the BIOS updater, it opens fine and runs a progress bar very fast, then restarts the PC, and BIOS is still my current 1.01 version. No error messages. I’m on Win11 Pro and have disabled all Windows Hello options (Bitlocker was already off). Please help

      Go to your Windows Settings, search for Core Isolation and turn it of before starting the BIOS update. Don't forget to turn it back on afterwards.

      I have the same exact problem. Tried disabling Core Isolation, unplugging all devices, turning off Fast Startup, Win Hello, Bit Locker, switching to Optimus. No matter what I try, it wont update the BIOS

       

      SOLVED!!

      After all that I mentioned, the trick was to right click the installer file and select "Run as an Administrator.” After the update it will ask you to confirm new AMD CPU codes, just type Y

      I have not been able to solve this issue. I am checking all the boxes:

      1. - Core Isolation: Disabled
      • - Memory Integrity: Disabled
      • - Fast Startup: Off
      • - Secure Boot: Off
      • - Bit Locker / Encryption: Off
      • - Windows Hello (Face + PIN): Disabled
        - Switched to Optimus
      • - Run as Administrator

      And yet, BIOS would not update :( 

      I am doing all of this from a local account - I am getting frustrated at this point. Anyone knows of any other settings that could be preventing the update?
