Ender 5 pro stock firmware

Trying to find the stock firmware for an ender 5 pro with 1.1.5 board. mega128p chip. I went to ender-series - Creality Cloud Firmware for 3D Printing and am getting all hex files, anyone know where I can find the bin file. I attempted to compile and flash with klipper and now the boards not responsive. I’d like to just flash it back to original.
