I don't really know what I did wrong. I probably watched a dozen videos on YouTube on how to upgrade the firmware on an Ender 3 V2.

Checked my board... It is definitely a 4.2.2.

Downloaded firmware from creality website.

Formatted mini SD card as FAT32. Copied  .bin file to SD card

When I turned on the printer,  the display lit up but did not display anything... also started an ear piercing buzzing sound.

It does the same thing now when I try turning it on with no SD card in it at all.

Any help would be appreciated. I feel like a farmer without a tractor. lol

It depends on which firmware you are flashing. A long beeping sound normally indicates the wrong firmware.

You must have a reason to update the firmware. If you don't add a new part like BL touch, no need to update.
