Waveshare 8.8inch DSI display does not work...

[Tim Curtis]

Revert the modifications to config.txt but make sure the bolded line below is still present. It should have already been there in the unmodified config.txt.

[all]
dtoverlay=vc4-kms-v3d
max_framebuffers=2
display_auto_detect=1
disable_fw_kms_setup=1
arm_64bit=1

Then in Peripheral Config under "DSI displays" try setting type to Pi Touch 2.
