Following up to my own post. Got some help on #ubuntu-phone on freenode.
I didn't mention that the fastboot commands weren't able to see the device
after I rebooted.
Seems like I need to use heimdall instead of fastboot for the Galaxy S4.
Now I need to figure out how exactly to use heimdall and how to manually
download roms.
The quest continues.

Hello list,
First post here, and I'm new to experimenting with mobile
hardware as well
as ubuntu phone.
I have a Galaxy S4 that I would like to experiment using Ubuntu phone.
Here is what I've done so far.
1) Following instructions here:
https://developer.ubuntu.com/en/phone/devices/installing-
ubuntu-for-devices/
2) Install all tools
3) put phone in developer mode.
4) I'm able to use "adb devices" and can see the phone
5) when I do adb reboot bootloader, the phone reboots, I see
the big green
droid and text that says "Downloading.. Do not turn off target"
And this is where I'm stuck.
Any ideas on what I should try next?
