Guess we both having bad day. Just started clean again, using 22454 ISO. This time using firmware. Responded fine, after I pointed ISO location in Settings. Forgot first time, so nothing was happening using CD option.
Update with 22454 works, not 22458 without bypass. Not sure if that was typo on version.
Think I may call it a night, start fresh tomorrow. Not been a good day.
I guess you didn't see my edit:
"ok not lost after all, found a previous copy and I'm back pre-TPM, boot to firmware is working again. π"
Not sure why it worked for me and not for you, is your host yellow zone? meaning CPU is the only non-compliant item?
Have a good one, thanks for all your input.
