Ender 3 pro has a constant beep after attempting firmware update

I pulled my dusty ender 3 pro out of my closet to upgrade the screen after not using it for ~3yrs and the new color display was stuck on the logo. After some digging I saw that I needed to update the firmware so after going to creality’s official downloads in installed the wrong firmware twice but on the second one it started making a loud constant beep now it’s doing it when I turn it on. I even tried to download the correct firmware and it stopped for a sec only to continue beeping. AND THE SCREEN IS STILL STUCK. I’m loosing my ■■■■ a 2hr project is going on 2 weeks. PLEASE HELP
