    HP 8560p, latest bios. Both generated 8560pa and 8560pb gives "Error code = 0x89" or Failed to load defaults... with same code. Any clues?

    While I was able to update bios from USB using win+b method, I can't downgrade it to test with another one. USB activity blinks a few times, caps is blinking forever, after many minutes and removing power sources old (latest) bios is still there.

    I located W25Q64CV flash, have a proper programmer for reading/writing it, so if someone can help this way, that's cool. Unfortunately HP in my country does not provide any chat/e-mail support and on US chat they declined to do anything because of not-my-region (sigh).

    The EZP2017 nor the CH341A worked (later I found out that the BiosChip can not be read unless it has 3.3 volt of power supply)


    I bought the Raspberry Pi 3B+ hardware and I made my own cable. Pictures attached. 20190205_113235[1].jpg 20190205_113235[2].jpg 20190205_113235[2].jpg


    I installed debian and run flashrom….it did identified the chip easily but (…always is a but) I got the message that is shown in the picture attached.


    Later I manage to read and save the file, but it only has 2.048 KB in size, smaller than the latest Bios (10.240KB) or the one that Mazzif sent to me (16.384KB).


    What am I doing wrong?


    I am stack.


    Like in Gotham the light is in the sky, calling for our hero. chip01.jpg massif.jpg

    Hope he sees it.

    rotfl.. u probably losing link to chip cause circuit around chip (caps or resistors) is draining it of current.
    best to just take chip off the board and read it.
