After having a few minor but anoyoing issues and had updated all drivers as a last resort I updated the BIOS following HP's guidlines. I have updated hundreds of BIOS in the past being a service engineer for many years so this was not new to me. After successfully updating the BIOS when it restarted the first thing on the screen was "Product Information not valid". Next, without pressing anything and waited a while it eventutally progressed to a second page (pressing Enter does it straight away) which at the end of this page says "FOTA Capsule Update Process Fail", it then restarts over again with the same messages. See pics.
I also have a productivity jacket with USB ports and I have tried creating USB with DOS startups, Window PE, Window Media Creation 32-bit and 64-bit, microSD, DOS with USB Floppy drive and it does not boot from any of it, and yes they are USB2 and not 3 and partitions are FAT32. It just won't respond to any of the F-keys, Esc or Vol-Down button, contineously restarts with "Product Information not valid" page. The only way I get to power it down to break the loop is to hold down the "Windows" key and the power button for a few seconds.
Lots of people are say hold this key and that key but the fact is on a number of sites I have noticed the same issue and that it doesn't respond to these key in order to select a boot option. It doesn't boot the OS or enter the BIOS and HP doesn't seem to be picking this scenario up. HP PLEASE HELP
