In the OP, I left a link to the official incremental update right from the OTA server (which I'll talk about a bit later). If you directly click it, it will return an Error 404, but that is not true since the file actually exists... But requires a special HTTP header to be visible.
Since I wanted to grab the OTA link now that, for once
, I finally got an OTA in this phone after always upgrading through fastboot images, I used wireshark to determine the server where it fetches it and the full file route. It turns out the header sends a special UA string as you can see in the picture attached: rsotaua 1.0, which is, most probably, a randomly generated string.
Now here's the thing: if you want to switch the UA you'll need an extension to do so. I've used this one
. As soon as it's installed, go to the Options of the extension and add it like here:
WILEYFOX rsotaua 1.0 Chrome Replace WF
Once the string is inserted, switch to it and hit the URL. The OTA should be downloadable now.
... Or you can just wait til someone mirrors it, like I already did
Lastly, as a side note, I'd also like to comment the following, regarding BSP:
Wileyfox's devices software is now in charge of this company, called BSP.ninja and that clearly defines themselves as a company to "launch an Android device without knowing where to start". It's said to be formed by former Cyanogen employees, or, at least Ricardo Cerqueira @aremcee
(which btw, is also in charge of the Open Source code available in BitBucket for the Wileyfox devices), since he's the owner of the domain. In any case, what I want to say is that the code is being done quite possibly by the very same people that did the job at the now dead Cyanogen, so it shouldn't be a reason to worry. Also, it'd be awesome if the team released a working device tree so that the community could bring custom ROMs just like you (the team) used to do.
