HP Pavilion 500-010xt BIOS update from JOS_815.rom v8.15 to 8.17 Rev. A, bricked machine:

[popgreen]

Hi, I flashed the BIOS on a H-Joshua-H61-uATX (Foxconn 2ADA) mainboard, with Board Label PCWPA0PCY4T00k from JOS_815.rom v8.15 to 8.17 Rev. Using Windows 8.1 with the safuwin.exe utility in Powershell. Once the process completed, I powercycled the machine and entered the BIOS setup.

I then checked the BIOS revision version and it stated bios revision 8.17 Rev. A (all is good I thought), then I exited the BIOS setup. Now only a blank screen is displayed with no signal at monitor.

I have tried creating a usb medium with FAT32 filesystem and placed JOS_817.ROM file now renamed AMIBOOT.ROM at root. No boot to medium.

I have tried creating a bootable medium with UNetbootin containing FreeDOS then dropping in safuwin.exe along with AMIBOOT.ROM. The machine will not boot (screen blank).

I have tried simultaneously pressing ctrl ++ and shift ++ at boot and no luck. Is this more than BIOS set to quiet boot somehow?

What are your thoughts on how to correct this situation if possible?

I think the method you used may have caused the problem.

Look at this HP video to try the BIOS flash/recovery described here.

Hi, I was able to use an external flash programmer to flash the BIOS onto the machine. https://h30434.www3.hp.com/t5/Desktop-Boot-and-Lockup/HP-System-BIOS-Update-Utility-Where-to-locate/...

I thank you for your prior help with this.😀

Glad to try to help.  The method described on that link is more involved than most users would try.  Glad you got it completed and it was successful.  Thanks for sharing.
