It still works fine, since Raspbian bookworm the files config.txt and cmdline.txt moved from /boot/ to /boot/firmware/ . So I did following before I run ./LCD-show installation:

mv /boot/config.txt /boot/config.txt.old
mv /boot/cmdline.txt /boot/cmdline.txt.old
ln -s /boot/firmware/config.txt /boot/config.txt
ln -s /boot/firmware/cmdline.txt /boot/cmdline.txt

After a lot of trial and error I made it work on bookworm x64 rp5, here is what I did:

1. fresh install of raspberry pi bookworm via official imager to sd card
2. follow the Guide https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A)_Manual_Configuration "For Bookworm System" section, but with a change:
3. dont add the 99-fbturbo.~, check if there is any configuration existing (from earlier trials) in the folder /usr/share/X11/xorg.conf.d and remove them (seems to be a issue with loading fbturbo (https://github.com/ssvb/xf86-video-fbturbo)
4. run startx, it should work immediatly
5. follow the rest of the guide

startup takes 2-5m for me from power to desktop.

Troubleshooting: connect via ssh and run startx, check the error and the error log

Hope this helps!

None of the fixes above worked. They keep selling these displays but none of them work because they haven't updated the software in 6 years. It's horrible to see. Not buying a Waveshare product ever again.
