I need Automatic Bed Leveling (ABL). I have seen this: FreeABL - the ultra cheap (free) ABL for Ender 3. However, after reading the description, I found out that I need to flash the firmware.

I had a lot of problems with this, so is it actually needed?

No, Marlin 2.x is not necessary you could use 1.1.9 as well, but, you do need to flash a newly configured firmware as this hardware change is not standardly supported by the current firmware on your printer.
