After various testing, it seems many users are experiencing various issues with the rooted System.img provided by the OP in this thread. Many report findings of "Sprint related elements" as well as various keyboard issues and things not working as they should. I wish I had the knowledge myself but on behalf of the community, I'd like to request for someone with knowledge of this guide to remake the same rooted system.img as in the original but this time confirmed with using the original stock Verizon SCH-I535 image downloadable here. Just formatted back to stock until issues can be resolved. The stock image (which I'm told this root is + su) lost all Sprint instances and any strange extra options. Also the Keyboards are back to functioning. Not to be a conspiracy theorist, but I feel that the root image has more going on with it than what we are told.
I'm sure many of us here would highly appreciate this effort and we can also carry out further testing as many users reported that soon as they flash back to that stock image, their issues have disappeared and everything starts working properly.
I will quote another user in reference to this:
