@blacPi, Welcome to HP Support Community. 

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

Thanks for reaching out about the screen flickering issue after the BIOS update on your HP Spectre x360 15-ch008ca. This kind of issue can sometimes occur if the new BIOS version introduces compatibility problems with display drivers or firmware. Here's how you can address it:

Confirm BIOS Version

Make sure your current BIOS version is indeed F.38:

• Press Windows + R, type msinfo32, and press Enter.
• Look for BIOS Version/Date.

Attempt BIOS Rollback to F.36

Yes, you can reinstall the previous BIOS version F.36, but it must be done carefully.

Go to the official HP driver page for your model: HP Spectre x360 - 15-ch008ca Software and Driver Downloads | HP® Support

• Select your operating system 
• Under BIOS, look for version F.36, click Previous Versions or Older Versions.

Install BIOS F.36

• Download the BIOS file and run the installer.
• Follow on-screen instructions. Your system will reboot and flash the BIOS.

If the installer prevents downgrading, you may need to use the BIOS Recovery Tool.

Optional: Use BIOS Recovery Tool (if downgrade is blocked)

1. Create a BIOS recovery USB:
   • Use another PC to download the BIOS F.36 file.
   • Run the installer and choose Create Recovery USB.
2. Insert USB into your Spectre.
3. Enter BIOS Recovery Mode:
   • Turn off the laptop.
   • Hold Windows + B, then press and hold the Power button for 2-3 seconds.
   • Release all keys. The system should enter recovery mode and flash the BIOS.

After Downgrade

• Check if the flickering stops.
• Update your graphics drivers from the same HP support page or via Device Manager.

I hope this helps. 

Take care and have a good day.
