Yes, there seems to be a root method for the SGH-T999N that I may have discovered. I synced/backed up on Google sync, when I was running on 4.1.2.
I Unintentionally updated to 4.3 not realizing root would be more difficult. I DID NOT use odin, just cause of the bricking hype. I did do some stuff with sideload, I think.
When flashing I used a 16gig micro SD card & also copied some extracted zip rom files via windows, straight to the phone.
Kept getting the error (in red) when checking for signature or something.(Ex. e: whole-file signature failed <se3>).
In the phone OS, I manually cleared cache, data, notifications, turned off & forced stop on several of the "update" & other potentially restricting security apps on the phone.
Booted into recovery via power + home + volume ? keys.
Wiped all data
"Upgraded ish" from external SD card.
Reset my phone & still got a signature fail.
Did the wipe & factory default again (after another reboot)
Flashed the same file again (I think) was CWM, Cyanogen or something. d2tmo, d2mtr seem to work.
Did a Factory reset & phone went to metro logo. Did a 2nd recovery reset before 1st one could finish & the phone seemed to go to an out-of-box state/first time setup. That's where I was able to enable superuser root, the box thing & backup?
Sorry I don't remember more detail at the moment. The Google Chrome backup seemed to help a lot for reinstalling rooted apps after 4.3 update w/ factory reset.
