Ok, I have a solution or workaround, but not a full explanation.
It seems permissions and such have changed between 4.2.2 and 4.4.2 and Llama isn't compatible, or maybe it's just not possible. The trick is to use the secure settings
app, and enable the System+ Module inside it. I think I also made Secure Settings a device admin, just in case, but unsure if that's required. Then go to the compatible apps tab and click llama help for instructions.
Basically, in Llama, instead of using the built in airplane mode commands you add an action "locale plugin", then choose "secure settings", "root actions", then "airplane mode". That lets you turn it on, off, or toggle.
If you purchase secure settings pro (about $1.50, in-app purchase via google play) you get access to a shutdown and reboot command. I can't find any other way to do this - even via a shell where you can usually do it the shutdown/reboot commands don't seem to be there.
