How do I use ubuntu-device-flash with the BQ Aquaris E4.5 and Aquaris E5
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.
unknown flag `recovery-image'
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
