Hello, I am trying to connect a Sonic Pad to my Ender 3 S1 Pro and it won't connect. It says klipper is not working properly and can't connect. I assume it is not flashing properly so when I boot up the 3d printer it is not overwriting the firmware. I took a looksie online and they say if your small touch screen is still looking normal the firmware did not overwrite. I tried a few different things to see if a brand new SD card was the issue and swapped to the one that initially came with the printer an 8 GB SD card. When going through the steps on the sonic pad and booting the printer the small screen started the start up creality title screen then froze halfway through. I thought the thing was finally getting somewhere however the pad never connected after waiting a while. After such I tried a few different attempts then I said screw it and wanted to go back. I tried loading the firmware with marlin I found online with the same stuff as my printer and now it won't go back to normal. I need help getting my printer back.
TLDR: Tried changing the firmware for the Sonic Pad. Won't work. Old firmware won't work either. I just want something to work and I hit a deadend.
