I have a ender 3 pro with a v4.2.2 board.
reading online it says i can put the new firmware on a sd card and it will update it.
What firmware do i need? I do not have a bltouch.
the current firmware is 1.0.1

You need to update the firmware until you want to add parts to your printer, like a BL touch, or new features been added in the new firmware. In your case, no bl touch, no new features, and your current machine is working well. So stay with it.
