What is the problem?
I installed the GPIO Shutdown plugin. After playing with the pin settings it uses to illuminate an LED and to initiate a shutdown, it now does a shutdown as soon as the pi starts up and loads OctoPrint. It must be looking at a pin that has some resistance(?) and immediately initiating the shutdown as soon as it boots up. So now I can't get in and change anything. About 15 seconds after I power on the pi, it shuts down. The power light stays on of course, but the network light stops and I can't access anything. I've tried to Putty into it but it is not on network.
How can I change the pin settings that the plugin is monitoring for initiating a shutdown? Or how can I start in safe mode so I can remove/edit the plugin?
What did you already try to solve it?
I created a Linux USB stick so I can boot my laptop into Ubuntu so I could try and edit files on the SD card (in my laptop). But I can't find what should be edited. Also, many of the files are locked and I don't know how to sudo into an SD card that I have plugged into my laptop (while running Ubuntu).
Have you tried running in safe mode?
I wish I could run in safe mode.
