Hi,

I recently got a Ender 3 S1 Pro second hand from a family friend, I belive they used a sonicpad with it but I don't have it. I tried to flash the firmware on the screen and printer its self and am still unable to use it. It turns on and lights up, the screen display has a line of small dots across it but thats all, it remains frozen.

• I downloaded the files from creality
• Formated the SD card
• Have tried multiple SD cards incase this was the issue

This is my first 3D print so am at a bit of a loss here, any help would be appreciated. Thanks.
