How do I factory reset a BQ Aquaris E4.5 Ubuntu Edition, from the handset

Question

I've been experimenting with the software on my handset, and I've got to a state where I need to recover with a factory reset.

This question covers how do do that with ubuntu-device-flash. How do I do it from the handset itself?

The factory reset procedure is several steps:

With the handset powered on in any state, hold down VolUp + Power. After holding them for around 10 seconds, the handset starts to reboot, and the screen blanks. At this point, release the Power button.
A menu will be displayed with three options. Release the Volup key.

Boot menu:

[Recovery    Mode]
[Fastboot    Mode]
[Normal      Boot]

Use the VolUp Key to select Recovery, and use VolDown to boot to that mode.
When the Ubuntu Logo appears, you are in recovery, and you can press VolUp to reveal the recovery menu. Use the on-screen prompts to select the wipe data/factory reset option.

Notice that this won't reset the system partition, so if you've made that writable in the past, you may still be in a strange state after this. In that case, ubuntu-device-flash is your best option.

In my case, I never saw the red LED

Hmm, I just tried again, and also don't see the red led. I wonder if it changed recently.
