Haha, didint pay attention. Just looked at OP real quick, lol

ok sorry guys they were error 7 on previous zip
im updating op with newer ones they both work tested

So, question for those more knowledgable than myself.
Would I now be able to just flash one of the N7100 ROMs, flash the Rogers radio, and the Perseus kernel and have a fully functioning Rogers i317M?
Am I missing something? I'm probably missing something right.
And I don't care if I temporarily lose LTE. I couldn't give a crap about LTE.

UCAMC3 vs UCAMH3 speed results
just another data point for folks... attached screenshot are the results from a quick modem speed test (using SpeedTest.NET). Just prior to upgrading my modem to UCAMH3, I ran speed tests on my current modem (UCAMC3)... then flashed the MH3 modem, and re-ran tests (same local server, immediately after flashing new radio). Results will obviously vary on your personal situation (geographic location, phone setup, etc); however for me the MH3 patch significantly improved my WiFi download speed (173%) and WiFi upload speed (24%). It was a basically a wash on MC3 vs MH3 HSDPA speeds. Ran 2 tests each on WiFi and 2 tests each on HSDPA (on both modems)... then averaged the results. Ping speeds were also significantly improved. Take it for what it's worth, but for me, appears the patch addressed WiFi speed improvement.
Thanks to 147aaron (for pulling the MH3 modem.bin) and Guitarboarder28 (for packaging the flashable zip).

Doesn't work for me. Unknown baseband shown after flashing. Data doesn't turn on. Phone then reboots after about 1 min.

What is an RIL?

RIL = Radio Interface Library...opinions on this vary greatly, but typically you should use a matching RIL for your modem for best results and battery life.

[OTA Update] Touchwiz 4.3 T-Mobile NOW available! MJC.

So my mother's non-rooted stock UVDMD5 S3 was sitting there and mobile background said update checker used 3 kb, so I checked the update checker and a 527.00 MB file started downloading. Just a heads up, is it the new download?
Edit 1 : Confirmed, this is Android 4.3 official.

Confirmed. Kernel version 3.0.31-1962493, Produced October 31.

Edit 2 : @DocHoliday77 has confirmed this actual OTA is ONLY for the SGH-T999..if you don't have one (you won't get the OTA) but DO NOT FLASH OR ATTEMPT TO FLASH ANY ODIN FILES!
Edit 3 : This has KNOX. Proceed at caution.
Edit 4 : have you ever been to jail? No? Me either. But if I had to picture it this update is much like it. Still to Docs leak thread or AOSP but don't touch this with a fine toothcomb if you want to root and later downgrade.

One way to find out, I suppose. I'm not currently rooted, the phone's bone-stock. Saw the download and immediately came here to see what was going on. Under 30 megs remaining.

check samfirmware...theres an update with over 800 mb

I guess that's a confirmation. Any issues? The AT&T version was riddled with problems.
Edit- Confirmed. Kernel version 3.0.31-1962493, Produced October 31.

According to Kies the update is MJC so its probably the same or similar to leak version DOC post .

seriously though, this is awesome! im bout to download in a min. will then upload to AFH so you guys dont have to wait on that blazing fast Hotfile!

Ok, something important to be aware of. From piecing information together from users around these and other forums, it appears just about everyone who had problems with the 4.3 update had updated via OTA. So if you choose to update this way, please let us know how things go. But if you do experience problems, DONT PANIC, Grab Your Towel, and start downloading the Odin flashable full firmware update.
This of course will include the T-Mobile kernel. I am 90% certain that the reason WiFi did not work with the leaked kernel is because we did not flash the full firmware update. I believe the WiFi modules needed to be built into the bootloader (likely the aboot partition to be exact). This is what I was attempting to confirm when I bricked my phone. So by flashing the full firmware/OTA update, you should have a fully working build, including WiFi if I am correct.
Aside from this, I would suggest reading through some of my posts in the leaked Rom threads. This is the same build that was leaked to us a week or so ago. Do let me know how things are going, I wish I could join you guys in the discovery phase of this "official" version, but I seriously doubt that other than the kernel working, and Knox likely being left out, it will be any different from what we have been using.
I do not see any reason you should not be able to root, but I will get an insecure kernel posted asap. As soon as my download finishes. In the meantime, if anyone wants the insecure kernel from the leaked build, it should be exactly the same one. Download here:
UVUEMJC_Insecure_kernel.zip
Hope everything goes well, and I am still here to help!

a root66 version will be coming soon. These have always been released within a day of us getting a new official release. Please be patient though, as I don't think mrRobinson has the S3 anymore. I will send him the download link as soon as I have it posted on my AFH account.
If he cannot get to it, i will do my best to get you guys a root66 build asap. But again, please be patient.
---------- Post added at 10:38 AM ---------- Previous post was at 10:34 AM ----------
You know, I have to be honest....I was hoping to be wrong about the latest leak becoming our official build! Was hoping they would update one more test build first, then we would have had another kernel/modem/build......oh well! I must say that I am quite surprised they went through with our release so quickly!
Someone must be watching us......

Thanks Doc, I'm in no rush.
Thanks for all your help, great appreciated.

oh, one more thing. if updating via ota, try Voodoo OTA Roitkeeper from the store. its worked in the past to preserve root.
and can someone pull the ota before applying it, and upload it for me please?
look in /data/fota, /data/temp, /cache/fota
its there somewhere, just cant remember for certain.

I'm bone stock rooted and software update complained about software being modified. Can someone confirmed that the T999L AND T999 are being updated.

[Q] I have had my phone rooted since it came out. Do I need to flash a new modem?

I switched over to Tmobile when this phone first came out and I haven't had a GSM phone in quite some time. I looked around and I am unable to find a thread for Tmobile modems for this device. My current baseband version is N900TUVUBMI7. Is there an updated modem that I need to flash?

There hasn't been a firmware update yet for the n900t. Mi7 is the original fw the Tmo Note 3 launched with. So there aren't any modems right now.
