Rolling back USB-C Controller Firmware

[sp345]

Is there any way to downgrade USB-C Controller Firmware? When you rollback bios it comes up with failed on USB-C Controller Firmware due to a version newer is installed. 

But many of the issues we are experiencing regarding USB-C and Display happened after a bios update and rolling back bios does not help. Then I'm left with the USB-C Controller Firmware.

We have been advised to roll the bios back but when we do this is does not roll back the USB-C Controller Firmware.

This did not make a difference. Non of them rolled back the actual USB-C Controller firmware and did not fix the problem.

Same (sinking) boat as you; assuming you've had the issue where the USB-C ports go AWOL and user is unable to charge without doing a 60-sec power button reset after that last buggy firmware release by HP?

Ludicrous that they've posted a lower version firmware but no actual way to downgrade due to the USB-C firmware incompatibility you flagged.

That is the issue to a T. After a long time of back and forth HP has admitted the problem and pulled the bad BIOS. We have been working with them as well to get a custom bios to roll the USB-C driver from 8.7.0 to 8.8.0. I don't know if or when they will release this publicly but hopefully it is sooner than later.

HP seems to be dragging their foot on this fix. We have a bunch of the HP EliteBook 860 G9 with this issue.  You would think they would speed things up sooner.

they just released a new BIOS update of 1.12 to 1.12.02 Rev.A. Hopefully this helps.
