Need bootloader binary for 4.2.2 with GD32F303RET6 #21

Hi:

I have an Ender 3V2 with a GD32F303RET6 chip on a 4.2.2 board. I believe the flash memory on the chip was corrupted by a static discharge and it will not boot or flash firmware from SD card now (display stays black after power on).

I can still communicate and program the chip using the 4 pin debug port and an ST-Link device.

Can anyone from Creality please send me the bootloader binary file for this chip so I can repair my board? I have already contacted customer service and they sent me here.
