Can not update bios on Workstation HP Z820

HP Recommended

Every time I try to update y bios (needed to install Thunbolt card) I have a error.  I try it by update via Windows, via dos and a USB stick, via the setup (F10) . Version today: J63 V01.02.

Error received: System ROM IMAGE is INVALD  (Version 3.90 - 3.91 and also for the last ver. 3.94)


I see the messages transfering Rom...100% but after verifying system ROM I have the message: Image is Invalid or a messgae (by update by windows: Unknown error.


Any suggestions or help?


Updates ae downloaded from HP website and done as in the instruction.

you need to update to bios v1.20 first  (sp61312.exe ) before updating to v3.94a (latest)


do not update from windows,  update from within the BIOS or from USB KEY using the files /rom image found in the DOS folder of the extracted SP
