How do I use ubuntu-device-flash with the BQ Aquaris E4.5 and Aquaris E5

The tool 'ubuntu-device-flash' can be used to update the software on an ubuntu phone manually. It can be used to change the device to a different 'channel' of updates and also perform a reset of the storage.

However, when I tried it with either the BQ Aquaris E4.5 Ubuntu Edition or Aquaris E5 Ubuntu Edition, it didn't seem to work, for example:

ubuntu-device-flash touch --channel ubuntu-touch/stable/bq-aquaris.en --bootstrap

Would be expected to wipe the device to factory state. However, it does not seem to succeed:

2015/03/27 13:58:35 Expecting the device to be in the bootloader... waiting

2015/03/27 13:58:50 Device is |krillin|

2015/03/27 13:58:50 Flashing version 20 from ubuntu-touch/stable/bq-aquaris.en channel and server https://system-image.ubuntu.com to device krillin

For production Ubuntu Phone devices, adb has been disabled in recovery, and this affects ubuntu-device-flash operation.

You must supply a recovery image with adb enabled, which ubuntu-device-flash will use temporarily while doing its work:

For BQ Aquaris E4.5 Ubuntu Edition (aka krillin), use recovery-krillin.img

For BQ Aquaris E5 Ubuntu Edition (aka vegetahd), use recovery-vegetahd.img

ubuntu-device-flash can then be supplied with the --recovery-image argument, eg:

ubuntu-device-flash touch --channel ubuntu-touch/stable/bq-aquaris.en --bootstrap --recovery-image path/to/downloaded/recovery.img

Note that when the command prompts you with:

Expecting the device to be in the bootloader... waiting

You can put a Aquaris E4.5 and Aquaris E5 in the 'bootloader' by holding down Power + Volume Up for a few seconds, releasing the Power button when the red LED lights as the machine reboots, and then selecting 'fastboot' from the device's boot menu.

If you get this error, that means you are still using an older version of ubuntu-device-flash. Please install the latest version using the ppa

sudo add-apt-repository ppa:phablet-team/tools

sudo apt-get update; sudo apt-get upgrade
