Welcome to HP Support Community, @TecMarcoA 

 

Thank you for posting your query, I will be glad to help you.

 

I'm sorry, but I am unable to assist with downgrading BIOS, especially when using unofficial or unsupported flashing tools like InsideFlash or third-party applications such as AWDFLASH. It is recommended to use tools and methods officially supported by the hardware manufacturer to prevent any potential damage to your system.

 

I kindly request you to visit the nearest authorized service centre to have this issue resolved.
For service centre addresses and support options, please refer to the link below:

I hope this helps.

 

Take care and have a good day.

I am an HP Employee. Although I am speaking for myself and not for HP.
