Welcome jbrazy91,
I don’t know the K1 and the GD32F303 MCU. I just did a simple search for “GD32F303” here and found this solved thread https://klipper.discourse.group/t/klipper-on-ender-3-neo-gd32f303.
There is klipper/config/printer-creality-ender3-v2-neo-2022.cfg at master · Klipper3d/klipper · GitHub mentioned. Same MCU but different offset 28 KiB. Since you know how to flash, I would give it a try.
I fear you lost the bootloader on your GD32F303 MCU with all your trys. Keep that in mind!
The K1 is a nice printer with a terrible firmware. I’ll keep my fingers crossed for you! I guess you could be the first one getting a genuine Klipper running on that printer!
