[Problem] HP BIOS Rollback/Downgrade

Hi

I own a HP Pavilion 15-ec2004AX laptop. OS Windows 11 22H2 BIOS v - F27

Recently I have been facing black screen issue repeatedly. I tried to resolve it by updating AMD graphics driver but it didn’t work. After lots of research and YT videos I narrowed down the issue as BIOS conflict with AMD graphics driver. I downloaded the previous version of bios F25 and tried to rollback bios but error. Not really sure why HP had blocked the bios rollback feature. i have already had a chat with the local HP service center but no joy

Does this issue have any alternate solution?

Hi Guys

Please suggest any way out of this issue. Currently the Laptop display seems to be working with legacy version of AMD Graphics v 30.0.13026.2000 dated 29-10-2021 and I have paused the windows update. But the black screen issue returns when I shutdown the laptop and switch on the next day

Then this is an issue that HP/AMD needs to work out… you do not have a “bricked” bios on the system and HP rollbacks when blocked are hard to do, hard core users risk their assets by using an SPI programmer and try to revert back the bios… with VERY HIGH risks of breaking the system.

Hi @MeatWar

Thanks for sharing details. Please if you may guide me about SPI programmer it will be a great help

You won’t get PRO on this on a snap of a finger… its needs to get experience on it, so read and learn, the rest its all to the user
