Ender 3 V2 4.2.2 beeping upon trying to upload firmware
So I have an ender 3 v2 here with a 4.2.2 board. I was trying to install a BLtouch, got the connections done then tried to upload the 4.2.2 bltouch ender 3 v2 firmware. The machine during this process starting beeping, starting as a constant beep then after around 5 seconds goes into long beeps with a very subtle short pause.
The screen is black. I tried flashing original firmware and doing the LCD DWIN_SET firmware update however the LCD never leaves the orange screen.
Does anyone know why this might be and what the fix would be?
