NEW UPDATE: I fixed my problem. I was formatting the second drive partition when I shouldn't have been. Must have missed that in the instructions or something. Looks like everything is working, including WiFi.
I need some help here. I have a new Pi 3 B+. I cannot get Octopi to do anything.
Some history on what I have tried. I downloaded the latest build I could find for the 3 B+ and installed it on a brand new 32GB micros SD card rated as required (10). My first attempts at booting produced a Kernel fail error which I'm told is because I had the wrong partition number in my cmd file. So I changed the 2 to a 6 on the end of this entry 'root=PARTUUID=c7cb7e34-06'. That worked in that the error stopped. Now all I get on my screen is 4 raspberry icons and a cursor. I've attached a keyboard and no response to any key.
I have a power supply that came with the raspberry. If I boot it using the SD card (Noobs) that came with the raspberry, it boots fine and I can run apps and everything. What am I missing here for Octopi?
