There was no mentioning of any platform, and - without putting thought
into it - I was assuming that what’s taken from step 1 is
platform-independent code. Putting a little thought into it, right, I am
now assuming that step 1 is about Gaia *and* Gecko, at least. The latter
being a platform dependent binary, it does make sense to think about
choice of platform.

Aren’t the processors similar enough?

The device has been out for some time. So I’m not too optimistic. OTOH
Alcatel should be obligued to give me the part of the source that is
under the GPL.
Concerning kernel configuration, I just got a reply from the author of
the guide: “IIRC I got it from device itself. Pull /proc/config.gz from
the device, decompress it, rename to .config and run 'make oldconfig'.”

Wouldn’t really matter. The phone doesn’t allow root access, and that
makes it unusable for me already. For day-to-day use it’s unusable
because I cannot run [backups][1]. For development use it’s unusable
because I cannot flash firmware.
Also, in step 4, one boots the phone with a custom kernel, but AFAICS
without actually installing it on the device. This seems quite safe to
do.
