Bricked HP Pavilion 500-010xt after BIOS FLash [Solved]
#1
Hi, I flashed the BIOS on a
Code:
H-Joshua-H61-uATX (Foxconn 2ADA)
mainboard, with Board Label
Code:
PCWPA0PCY4T00k
from
Code:
JOS_815.rom v8.15
to
Code:
8.17 Rev
. Using
Code:
Windows 8.1
with the
Code:
safuwin.exe
utility in
Code:
Powershell
. Once the process completed, I powercycled the machine and entered the BIOS setup. I checked the BIOS revision version and it stated bios revision
Code:
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
Code:
FAT32
filesystem and placed
Code:
JOS_817.ROM
file now renamed
Code:
AMIBOOT.ROM
at root. No boot to medium.
I have tried creating a bootable medium with
Code:
UNetbootin
containing
Code:
FreeDOS
then dropping in
Code:
safuwin.exe
along with
Code:
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?

#2
I was able to flash the BIOS with a CH341A programmer using the flashrom program with openSUSE on my HP-Pavilion laptop.

Code:
# flashrom -p ch341a_spi -v

Code:
# flashrom -p ch341a_spi -c W25Q64JV-.Q -w JOS_817.ROM
Code:
flashrom v1.5.1 on Linux 6.13.0-1-default (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Found Winbond flash chip "W25Q64JV-.Q" (8192 kB, SPI) on ch341a_spi.
===
This flash part has status UNTESTED for operations: WP
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to flashrom@flashrom.org if any of the above operations
work correctly for you with this flash chip. Please include the flashrom log
file for all operations you tested (see the man page for details), and mention
which mainboard or programmer you tested in the subject line.
You can also try to follow the instructions here:

Thanks for your help!
