I am currently working with dev Geohot to get us root access for the SGH-I527 with Baseband Version I527UCUBNE7. All known root methods have been tested and proven to not work with this version of android with this baseband, due to the extremely locked down nature of Samsung Knox on this device.
I, personally, have been throwing every exploit I can think of at this device, to no avail. As of the time and date of this post, we have a donor ready to help the cause (Special thanks to caguas56). That is why I'm proposing a bounty on root access for this phone (SGH-I527 AT&T US version only, although there is a high possibility that it'll work on the Sprint,T-Mo and VZW variant).
The first developer who can successfully get ROOT on KitKat with baseband I527UCUBNE7 and demonstrate this with a successful public test will be awarded the bounty. The bounty will be split equally between devs and donors willing to team up.
I'm in for $10 at the moment, and I'll piss away more if needed down the line.
Who else is in? LETS GET THIS DONE, PEEPS!
