OCLP update botched root patches on mbp11,1

[nosflowm]

Everything was working fine with OCLP 0.68 on my MacBookPro11,1 running Ventura. Then, I took the plunge to update to OCLP 1.2.1. The computer runs through the first few boot stages fine, but the progress bar hangs about 1/4 through. Following the procedure in https://dortania.github.io/OpenCore...OOTING.html#stuck-on-boot-after-root-patching I was able to boot without root patches.
Tried a fresh install of OCLP 1.2.1 (rather than updated). Same outcome.
Downloaded OCLP 0.6.8 (which previously worked) and installed. Same outcome.

I've tried reading through the documentation, but it's not clear to me where else to clean up after a botched update. I don't mind trying a few things, but as each attempt takes about 10 minutes (between boot attempt, launching recovery, deleting files in Data/Library/Extensions, and booting again) on my pokey old hardware, I'd rather try informed guesses over my random attempts to delete things.

I'll be happy as a clam if I can revert to 0.6.8 and get the root patches working again.

Thanks in advance for any help that can be offered!

Replying to my own thread in the absence of any other comments/advice/suggestions/sympathy/acknowledgements that this post exists.

I also tried installing OCLP 0.6.7 to no avail. Clearing NVRAM and SMC didn't help either.

I'm able to boot all the way through by deleting AppleIntelHD5000Graphics.kext, however this leaves me quite hobbled without "GPU" acceleration.

I'd really appreciate any suggestions on how to re-enable this kext.

You might have to remove root patches before updating the EFI loader and then update the root patches.

Great suggestion! I was taking the shortcut of removing and reinstalling in one step, without reboots. This time I tried:
Remove root patches
reboot
Reinstall "Build and Install OpenCore"
reboot
Install root patches
reboot

Same behavior (hang at 25%). But I did notice that after removing root patches, it retained /Library/Extensions/AppleIntelFramebufferAzul.kext and retained the ability to scale the display to other than 1 framebuffer pixel = 1 display pixel (Control Panel / Displays / Larger Text).

This confirms my suspicion that something is retained and not deleted when I remove root patches.

Any thoughts on how to clean things up even more?

Sometimes it helps to boot in safe mode and install the patches.

Thanks for the suggestion. I gave that a shot (safe mode for all steps, removing root patches, reinstalling OpeCore, and reinstalling root patches). I'm afraid to report that it didn't help. My system still can't boot with AppleIntelHD5000Graphics.kext enabled.

I welcome any other suggestion that might help.

In case anyone from the future is curious, OCLP 1.3.0 didn't help. I wasn't able to download the Ventura install pkg and use OCLP to create a boot disk and reinstall the OS (it claimed I couldn't "downgrade" my OS). But by waiting long enough, Apple provided a 13.6.3 Software Update that cleaned things up enough. No actual solution to the underlying problem or awareness of its cause. Best of luck, future Internet!

• Boot into Safe Mode>Revert Root Patches>Reboot>Start Root Patching>Reboot. This procedure S/B inserted into the docs. Also, is the Host model selection correct? The No downgrade "feature" is part of macOS not OCLP. Facts matter.
