I have an Ender 3 v2 with a 4.2.2 board.
I have been able to flash this firmware:
Ender3-V2-BLTouch-20220205.bin from
https://marlin.crc.id.au/firmware/Ender%203%20V2%20-%20BLTouch/
and I fixed the display with DSET files.
I am following the wiring as shown on the link above, using the BLTouch port on the board (see picture above with board version). (NOTE: I have seen other sites using part of that port and the z-port for the black and white. That requires other build switches, but this site shows using all the pins on the BLTouch port on the board which I am doing. I have checked about 5 times to verify all pins are wired correctly. I have an original BLTouch (v 3.1) and the wire colors are even the same. See board version picture above this BLTouch end:

I have the z-switch disconnected at the switch.
When I turn on the printer, the BLTouch goes through 2x down/up routine while red (with a blue dot) and then stays in the configuration with probe up.
PICTURE
If I select on the screen to have it “auto home”, it will move up (z) about 10 mm, then home to the limit switches on the x and y and move to the center. But then it moves up 10 mm and goes through an down/up routine again (red glow with blue dot) and then switch to blue glow with a blue dot (or maybe glow from blue dot led) and probe down. Sometimes it will then repeat this (minus the move up to start) and then just sit at the blue dot, probe down and do nothing. IT NEVER MOVES DOWN. NOTHING NOTED ON SCREEN, BACK TO MENU.
PICTURE
If I choose to “Level” from the main menu, it does something similar but on the screen it says “Home Z First”.

I tried that first.
I have also tried to “load defaults” “save configuration” (says it save it). Turned off printer, back on, and tried all of this again with same results.
I don’t know what to try next. HELP!
