Interesting, I'm getting an identical result.

Change the keyword to "Catalina 10.15.5 Update". It should work.
Plan C:
- Find a spare USB flash disk or use an existing USB install disk.
- If using a new USB flash disk, format the disk in Disk Utility:
- Name: Boot Test
- Format: MacOS Extended (Journaled)
- Scheme: GUID Partition Map
- Mount EFI partition of the USB flash disk.
- If there's an EFI folder in the EFI partition, rename the EFI folder to something else, such as EFI-OLD.
- Follow Step 1 of the Catalina 10.15.4 Mini-Guide except for the 3rd bullet (3rd bullet copies macOS installer to the USB disk, which we don't want).
- Download the ZIP file from the same Catalina Mini-Guide. You will find 2 config files there:
- config-IGPU.plist
- config-AMD-GPU.plist
- Ignore the first one. Instead, copy your existing RtVariables and SMBIOS sections into config-AMD-GPU.plist. You can use a text editor like BBEdit or a Plist Editor such as ProperTree to copy those two sections.
- Then rename config-AMD-GPU.plist --> config.plist.
- Remember to follow the other instruction in Step 1 of Catalina 10.15.4 Mini-Guide, including copying drivers, kexts, and ACPI files from the ZIP to the new CLOVER folder.
- Then boot from the USB flash disk by pressing F12 at BIOS splash screen and choosing the USB disk.
- At Clover Boot Menu, select the normal option to boot into macOS.
- Does it work?

Always start with a full bootable backup. The update from 10.15.3 to 10.15.4 was very troublesome. It was the worst update experience! I strongly recommend following "Plan C" in that post. There is a 90% chance of failure if Plan C is not followed.So is this only if a simple combo update process fails? Or should I follow this anyway as a fail-safe option?
Seems that the search keyword should begin with a letter, not a number.
Indeed. Any known reason why?
YES SIR!Recent contributions by @joevt and @Inqnuam for simplifying the manipulation of Thunderbolt DROM have been added to Quick Reference to Mini-Guides and Micro-Guides at the top of Post #1. In particular, links are in Section 8, which is devoted to all things Thunderbolt.
I still expect to post a Mini-Guide for ThunderboltUtil and to update each of the Thunderbolt DROM Micro-Guides. Coming soon.

I completed Steps 1-3 as recommended several times, but I still get the same "power supply unavailable" error.Interesting (not in a good way ). The screenshot says "power supply unavailable". Please try this procedure from Post #1:

I am running the GC-Titan Ridge with patched NVM50 (@Elias64Fr/@CaseySJ) and an LG 4K UltraFine 24" monitor. I am currently running 3 monitors in my configuration. With all of my tests, I have found that with patched firmware, I must have a monitor connected directly to my GPU. My TB3 monitor will not activate during boot until it's almost completely loaded to the desktop. This is consistent with your experience. Here's a report on my latest findings:
