After building my Ender 3 printer, installing the CR touch auto bed leveling kit, and the Ender-3 Marlin2.0.6 CR-Touch or BLTouch firmware for it. I turned it on and tried to auto home but it just made a little noise and then displayed "Homing failed printer halted please restart". So I tested the end stops with a multimeter and they all seemed fine. I did some research and found the CR touch firmware could be the problem and installed some newer firmware (Ender-3Marlin2.0.6HW4.2.2GD) and nothing has changed. What should I do?

The reason I was having this problem was because of a file I had extracted that was on the sd card. I noticed an orange dot at the end of the extracted file, so I thought it was probably flashing and interfering with the firmware. After I deleted the extracted file and flashed the firmware it ran perfectly.
