Actually the T-Mobile update is only for the non-LTE version which wasn't even on the leaked time table. I guess the issue is LTE modem support but that is pure speculation at this point.

Android 4.3 Experience

I just downloaded the 4.3 Update. Download was 623.10 MB.

Install was problem free.

However, I have an issue with the notifications popping up continuously for the downloaded files. You can clear the notifications, but they will reappear after awhile.

Email app is new and takes some getting used to. The delete, refresh etc is now at the bottom of the page.

Keyboard is remembered after a reboot. No need to set to Swype.

Messages now appear on the locked screen.

Svoice is updated. I dont really use it.

Thanks in advance...

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] loserskater:
Here is the stock OTA update. flash in recovery. This was taken straight from my device.

This will put you at stock 4.3! No root, custom recovery, or any kind of modification was made to this.

You MUST be on stock 4.1.2 or it will fail to flash. Use this if you were on the 4.3 leak or if it says you're up to date.

I shoudn't have to say it but I747 only!

NOTE: Some users on the Tmo forums have complained of not being able to flash anything other than 4.3 in odin after upgrading. You should be able to flash a cutom recovery, but if you're unsure about 4.3 and want to stick with 4.1.x then DO NOT flash this. I'm currently working on a modified 4.3 with only system, boot.img, and modem and will have something up soon.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] IISaintII:
First of all thanks for doing this...

Have a question for you... Ur ROM doesnt have root. So can i root it? Or there is no reliable rooting method for 4.3 version. Last i used cf root in 4.1.2.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] RockRatt:
I am guessing that they used patch files inside? Like they did with the ATT S4 4.3 update. This would probably be why you would have to be on 4.1.2 firmware? Hopefully we can get the FULL Odin style package from it if this is the case.

Doing a system dump right now and then will try auto root

That's correct. I doubt we'll see a odin tar. Not sure what AT&T's MO is, but I don't like the lack of odin files.

I'm going to do what I did with the 4.1.2 OTA update. Flash it and dump everything then create a flashable zip.

By the way, for anyone who wants to get the downloads to stop appearing, go to the downloads app and clear history
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] loserskater:
We have a successful system, boot.img, and modem dump. (They were all patch files so you couldn't just pull them from the OTA). Enewman is going to mess around with it because I have to go to work soon. I hope to get something up before tomorrow morning.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mrhaley30705:
I'm thinking out loud here. If you have to be on 4.1.2 to update to 4.3, try downgrading to 4.1.1 first. It will most likely turn into the old double update, but it's possible that kies will then work. Iirc , kies3 will only work if your already on 4.3.

If this ota is like the leak, and it may not be, you can still use Odin to downgrade. It may bootloop, but a factory reset in recovery will fix that (back up your stuff first, as it will wipe your internal card).

Also, if mjb is like the mj2 leak auto root will work, but you will lose root when you reboot (thanks to Knox and SELinux enforcement).

If I can get a rooted version of this similar to mj2 (no Knox/SELinux passive), I think I can make an Odin flashable version. If I'm able to get time away from the familial unit, that is ;)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] norbarb:
Or you can rename this to update.zip and push by ADB if you want to update AS IS. DON'T update from external card this will wipe your data.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] loserskater:
Kies will not work to update to 4.3 because it is OTA only. I have upgraded everything including bootloaders but will not be testing a downgrade because I do not want to go back to 4.1.x and because I need this device. [MENTION=2972841]enewman17[/MENTION] has an extra device that he might try it on. One thing I noticed is that wifi was not working until I upgraded the bootloader and that is similar to the tmo release, which isn't a good sign because if it is similar to the tmo release, downgrading is how a few of them have hard bricked.

Auto root does work, and it works well. No need to mess with selinux at all. Knox has caused a few issues and will likely need to be removed but selinux hasn't been causing any issues yet. Another thing is that I've rebooted multiple times and root has been perfect.

I flashed the update file and somehow lost the AT&T boot animation, or more specifically, the sound and the image of the globe but the wording and the droplets (or whatever it was) disappeared. Everything functions on the phone but the boot animation glitch during startup is annoying. I've tried clearing cache and reflashed the update to no avail. Does anyone have any suggestions on how to correct this glitch? I'm thinking when I need to sell the phone I would want the phone to look and function with the fully functioning boot animation.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Evilweasel47:
I tried rooting through CF-AutoRoot, but it only gives permission for apps that already had root in 4.1.2. In my hurry, I forgot to give root permission to File Manager, so I am unable to delete the Knox apps. I tried freezing Knox apps through TiBU (which still has root access) but no luck. Every time I try to get root access, Knox blocks it. Help?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Laugher19:

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
I'm going to warn everyone. if you update to this I don't think you can downgrade your bootloaders. I just bricked my extra S3 trying to downgrade. I can't say for sure that is what caused it but I'm fairly certain. So please do not flash any of the recovery flashable bootloaders we have floating around in the threads if you have updated to the new 4.3 OTA
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] TH3F4LL3N:
