also if i don't necessarily need to root to load a custom ROM where could i be directed to be able to load 4.4?

Thanks!

The 4.3 OTA installs Knox without checking if you want it or not. Fortunately there are ways to remove it after the fact. Most suggestions I have seen recommend using CF-AutoRoot, updating SuperUser, and then going into SuperUser to disable Knox. You don't need root to install custom ROMs but as far as I know you need it to remove Knox. Removing Knox seems to be necessary in order to get the custom recovery required to flash custom ROMs.

|Guide|How-To| Root & Install Custom Recovery for 4.3 Update
[CWM][4.2.2/4.3/4.4] DE-SAMSUNGNIZER Script V5.0.0 - Clean all unneded Samsung Crap contains scripts to remove Samsung bloat and others that seem to just remove Knox.

I was about to offer no comment on the ROM to which you linked because it is in the Verizon forum, but then I noticed the d2lte in the description. My understanding is that d2lte is good for all US SGS3 variants. (Gummy says this in it's forum.) Maybe you can get around using a custom recovery with some ROMs, but the Gummy ROM comes as a recovery flashable zip. So, it looks like: root, remove knox, install custom recovery, flash rom.

From reading quite a few ROM threads I have learned that the updater scripts have code that indicates which devices they will work on and will cause the install to fail if you are trying to flash an incompatible ROM to a device. Sometimes these scripts have not been updated to reflect ROM compatibility with devices and editing the updater script will correct this. This is best verified in the ROM thread. Something to check for yourself before posting would be that you are using a compatible ROM version. The d2lte files should work with any of the US variants. If you downloaded one of the older files there is then the need to make sure it works with your device, unless you are confident about editing the script.

Other possible causes of your error:
1) it could be that the zip is on the external_sd and the installer expects it on the internal
2) you have a bad ROM download

SGS3 SGH-i747

TW 4.1.2, stock, rooted,
TiBu frozen

Samsung Captivate SGH-i897
Currently CyanogenMod 10.1.3
resurrected from softbrick using 4-2ndtwin's Heimdall OneClick to stock Gingerbread - 2.3.5 - kk4
ROM history Eclair > Froyo > Gingerbread > CM9

Look in the development thread for a way to flash back to stock 4.3.

Default Root problem solved

I have an AT&T S3 SGH-i747. The problems I had with rooting was all related to Knox, unfortunately I had no way to get rid of Knox.

Please follow the web link and follow all the steps in order. The short version of the steps is you install the TWRP recovery using Odin, then boot back into recovery , install SuperSU and then Knox removal script via recovery. After that enjoy whatever custom ROM you want. I'm running the KitKat 4.4 now

As a note getting to the correct download link can be a pain due to the bait and switch of the "download now" button with other shareware apps but the links provided to lead you to the correct zip files.
