no joy: Windows 10 Pro b2004 (May 2020) FZ-G1 mk1

So Microsoft did its thing and I upgraded my FZ-G1 to the latest bestest May 2020 update. Well that was a bad idea! I had the dreaded black screen... but this time, it doesn't get past the Window logo on bootup! System Restore also failed.

So I tried to do a clean install of b2004 - NO JOY. It installs and goes through the initial setup process just past account creation. But on the reboot, it gives me the unresponsive black screen (no backlight either) after the Windows logo. External HDMI monitor doesn't help either.

Is there any way to download older Windows 10 Pro ISOs from Microsoft? I stupidly didn't keep any ISOs and even running older MediaCreationTools forces an update to get b2004's tool.

Update 1: With no internet connectivity on install, it will boot to the desktop. However, the entire system is slow as molasses (well, even worse than before with b1809).

I have a FZ-G1 running version 2004 no problem. Have you installed the Panasonic One Click Driver Bundle?
