What is the problem?

I want to install OctoDash or OctoScreen, but everytime I try it I can instantly reinstall OctoPi.
Note: I can't use a other OctoPi than this (its a download-url, cant find the site anymore)

What did you already try to solve it?

I tried that what stands in the guides, but everytime it destroyed the LCD-Driver(and by the way i dont need it if I edit /boot/config.txt with this on the bottom dtoverlay=piscreen,speed=16000000,rotate=90)

Have you tried running in safe mode?

No

Did running in safe mode solve the problem?

Didn't use it.

Doing a little investigation into that link it appears that they have minimal changes to the octopi image itself, mainly profile related stuff.

The one bit of interest is that image uses a custom OctoPrint install, as seen here.

Which can be traced back to their fork of OctoPrint, and the only difference between their version and core OctoPrint is a little tweak to the serial communication layer.

                serial_obj.setDTR(False)
                serial_obj.setRTS(False)

Not sure what those specific commands do on the serial object, but probably wouldn't be too difficult to apply the same changes to the current version of OctoPrint.

All that being said, I think installing OctoDash on that older bullseye image you linked would work out better than current stable versions because that's what it was developed on. Might be easier to debug the lcd driver issues. Does it completely kill the underlying OS from working at all, so OctoPrint doesn't load and you can't SSH to the pi?

one question: could we make, after we finished it so that it work, a guide for other people who have a ENTINA TINA2S how to Install a working OctoPi with the newest version and with OctoDash installed? and could you help me updating it right, so that i can use it how i should + with OctoDash? I really don't know how i should make this, so please say how I could make it!
