[Verizon Samsung Galaxy S 4] k1mu:
Here's what's in the file.

I recommend NOT trying to cut and paste it from here as you've got to get it exactly correct for the sha1sum to match - that's why I zipped it.

<?xml version="1.0" encoding="UTF-8" ?>
<!-- It can be added for each operators like below form

<ABC> -> sales code
<sapient>true</sapient> -> feature1
<burton>false</burton> -> feature2

</ABC>

each name of tags are will be environment variable with "ro.csc."
ex) "ro.csc.sapient", "ro.csc.burton", "ro.csc.libtech" <== you could use them at any section.
also, should be added between <FeatureSet>

I don't think that it's necessary to be unrooted. Several people have updated and have kept root.

However, If you've tampered with the stock contents of the phone, the update will fail. I posted a script that you can run that will look to see if all of the required files are in place and intact; that runs OK on my phone, so the update should be fine. I'm still on the fence about taking it before there's a root method, though.
