Initially, my plan was to add the text about the Emma flashing tool as it has existed in the flashing instruction of Xperia X (Windows) only. Now that I had updated the Xperia X document it came to my mind to describe the Emma tool in this document rather than in the document of a fading product.

Eventually, I did not just add the Emma section. The text was an old product of mine from several years back and looked horrible. Reverting a phone back to Android should be the last resort. It is definitely unpleasant for the user. Hopefully, the document is now a little bit easier to understand.

I updated the screenshots (and dropped some duplication) and tried to make them visually nicer-looking. There were some hyperlinks missing or incorrect, too, in this document.
Now we can point precisely to the Emma section from other documents if there is a need to.

Apologies, git diff may have difficulties showing the differences.

The PR title could be a bit more specific. i.e. Which document are we updating?

Actually, now that I think about it, the whole "Update the document" is kind of pointless. Almost all PRs in this repo update some document. I suggest "Add the use of Emma to Reinstalling Sailfish OS document"

All reported issues fixed (afaics). How does it look now?

Almost there. At least in my opinion - of course it's possible that JP finds something else :)

Looks good to me, but if you are fixing that one extra full stop then I would propose that on line 165: Should you get a "403 permission denied error" when trying to download,
would be changed to: If you get a "403....

Done.
