CR Touch and Firmware Issues

Hi all

Having some very frustrating problems with my Ender 3 (original).

It’s got a 4.2.7 board and I’ve just installed a CR Touch.

It was working fine after installing cr touch with creality firmware (https://www.creality.com/products/cr-touch-auto-leveling-kit). 16 point levelling etc.

Turned on a day later and it’s in Chinese. Change the language settings and try to run a print and the head starts probing off the bed and then trying to drill through the build plate. Doesn’t seem to even try and level the bed.

Now it won’t accept any new firmware (the probe offset never changes). The SD card is working as I can try and run a print.

Any ideas? I’ve tried to install firmware via Cura but you can only install . hex not .bin via a PC.

So it’s currently bricked as I can’t even revert it by removing the CR Touch.

Cheers

Rename the firmware .bin file on the SD card. Creality boards will not update with firmware of the same name as the previous update.
