Firmware Upgrade - Error 259

HP Recommended
HP 800 G1 USDT
Microsoft Windows 10 (64-bit)

Hi .....I have posted this elsewhere on the forum but to no avail so hoping this is the right place ........ 


I am currently upgrading the Firmware on a HP 800 G1 USDT as part of a SCCM Task Sequence.


The upgrade is happening during the WinPE stage at the very beginning of the build and runs the following command - hpqFlash64.exe -ppw.bin -s -r

The upgrade fails with an error code 259. I believe this to be Password file not found.


When looking in the download directory that the files have been copied to the pw.bin file is missing. However upon recreating the issue i can see the file does get downloaded into the correct content location on the machine .....but is then removed after aprox 10 seconds.


Has anyone seen this issue ..... would the hpqFlash64.exe remove the file? There isnt really anything else on the machine at this point that would randomly remove files (no AV etc).



Any help would be appreciated.
