By the way magic-device-tool was not working because the link for the recovery image was not correct.
@ll yeah I know, that's why I said "if you feel adventurous" and "you can play with MDT".
What I mean is there's some ways to do that, for example looking at the code of MDT you can see it tries to download the recovery image from http://mdt-files.com/downloads/magic-device-tool/recoverys/recovery-arale.img which doesn't exist anymore so you can replace it with http://cdimage.ubports.com/devices/recovery-arale.img (probably that's the one you need BUT I really don't know because you're trying to do some archaeological thing).
I think you get the idea, you can customize your own MDT or see what that script does and type the commands (pointing to the right server) in your CLI. Of course, the recommended way to get the best results is to do this using Ubuntu 16.04 with all the needed tools installed (like phablet-tools).
Edit: the legacy channel for your device is still online as you can see here http://system-image.ubports.com/ubports-touch/legacy/arale/
