The device is a Nexus 4, currently running Android 4.4.4, though I have tried with 5.0.1. I am using the instructions at http://developer.ubuntu.com/en/start/ubuntu-for-devices/installing-ubuntu-for-devices/ to install Ubuntu Touch (devel channel) on a Nexus 4, single-boot. Everything works as expected up to the point where I run

Rather than rebooting as the instructions say it should, the device stays on a Recovery screen. At the top of the screen I have:
Ubuntu Touch (CWM-based) Recovery v220.127.116.11
- reboot system now
- wipe date/factory reset
- wipe cache partition
- backup and restore
The "advanced" menu option leads to:
- reboot recovery
- reboot to bootloader
- power off
- +++++Go Back+++++
It's not frozen - the up and down volume keys and the power button work to select from the menu. The problem is that no menu item leads it to boot in to Ubuntu. It will boot back in to Android, to the bootloader screen or to this recovery screen, but there's nothing I can select to load Ubuntu.
Any hints as to how to get around this blocker?
