Hello everyone,
I need your help.
I have a K1 MAX, manufactured around 2023. I bought it used in 2024. It was rooted, and Klipper (GitHub Guilouz) with Mainsail was running smoothly and stably.
On Sunday, I noticed that updates were available for the “Klipper modules.” I enabled the updates via Wi-Fi and Andreas Reitberger’s app. Later, I noticed that one module had problems with the update that couldn’t be fixed.
Using SSH access and a helper script, I first tried to install the individual modules. That didn’t work. Then, using the helper script, I uninstalled all the modules one by one and then successfully reinstalled everything.
The problem seemed to be solved. The printer screen displayed a notification about another update. I saw that it was from Creality, but in a moment of madness, I started the update. It ran without any further problems—those only started afterward.
After restarting the K1, only the Creality logo was visible on the screen.
SSH access is no longer available. Nothing is reachable via port 4409. I can access the printer via its IP address (without specifying a port) and print, but without the screen. Since rooting is no longer possible, I tried reinstalling using different bootable USB drives, but without success. The USB drive was never recognized at startup. I tested several different USB drives. I also prepared a bootable USB drive using Diskpart and flashed an IMG file with Balea Etcher.
Finally, today I tried direct access via the USB-C port on the board. All cables were disconnected, and I’m certain I was using a USB cable with power delivery. It was impossible to get the board into flash mode. The LEDs on the board remained off. I tested two laptops and three different cables.
I can access the printer via the Creality slicer and Wi-Fi – unfortunately, that’s all I can do.
