Failure installing Ubuntu Touch on Nexus 4 with AOKP -- adb push "protocol failure"

view story

http://askubuntu.com – I have a Nexus 4 with AOKP already installed. I ran "phablet-flash -b" once and everything went fine until I realized I didn't have fastboot installed, so it errored out at "sudo fastboot flash system /root/phablet-flash/95/quantal-preinstalled-system-armel+mako.img" with my phone at the recovery screen. I installed flashboot and retried, but now when I run "phablet-flash -b", after everything has been downloaded I always get "Error while excetuting adb push /root/phablet-flash/95/quantal-preinstalled-phablet-armhf.zip /sdcard/autodeploy.zip"; "protocol failure". I definitely have enough (HowTos)
