Hello,

After applying the BIOS update suggested by HP Support Assistant, my laptop  (Pavilion 15-cw1004 la) is stuck on the " System BIOS recovery failed" loop as specified here and here. I already tried everything in this article and nothing seems to work, including the USB recovery tool.

The only accepted solution seems to be to send the device to official HP service and have a motherboard replacement. However, the approximate price listed by HP for this service is almost the same price I originally paid for the laptop so I'm trying to exhaust my options before going there.

Manually flashing a BIOS image file to the EEPROM with a CH341A programmer seems doable, assuming I  can  get my hands on the binary BIOS file. Someone seems to have already done it succesfully but it seems to be a rather old computer (the .exe is from around 2012). Is there something particular about the BIOS install/booting process that could make this fail? Has anyone else ever done this before?

I have exactly the same issue after a windows update of the bios.

Most recent BIOS (sp134485 from HP website) extracts BIOS_Update.exe but that does not open on five different computers that I've tried including two HP laptops. Older versions open but say "invalid signature" or something like that when I try Windows+B and turn it on.
