[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Don't get your hopes up too much guys. I doubt it'll get its own separate forum for two main reasons.

First is that the two are highly compatible in that they bothhave identical partition layouts and the roms in this section will work on either model. Considering that development on the T999L will likely be slow, most people will be coming here for roms, mods and support anyway.

2nd is the slow development itself. Most who do this stuff already had the orig s3 and any looking to upgrade will be going to the s4 or better.

Also consider the other variants. The T999V, the US Cellular, the straight talk, etc. If they all get their own forums there'd just be to many to moderate and would in the end cause more confusion. And as I mentioned, everyone would wind up here anyway.

You can ask of course, just don't go in expecting anything.

I've already found out that the advanced boot mod doesn't work and also when I flashed ktoonez the settings screen was all black so what about the multi Windows mod did anyone have any success
[T-Mobile, Samsung Galaxy SIII] MotoDefier:
While I have not tried the mod, I have confirmed with Samsung Support that this device will recieve that update, tmo has no clue as always
[T-Mobile, Samsung Galaxy SIII] Slypnslyde:
Cool, but for now there's no kernel to flash othet than the stock one
[T-Mobile, Samsung Galaxy SIII] MotoDefier:
Correct
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
You can try others as long as they are built from the MD5 kernel source, I don't see why it wouldn't work.

As far as mods go, you just have to try them. No other way to really know if one will or won't work.

I've found LTE to be very sensitive to both signal strength/quality, and the individual towers backhaul. This is my i747 with stockorama v2, T-Mobile kernel, and latest att modem.

I can have full bars and get 20Mbps down and only 3Mbps up on some towers. Overall avg is about 20 down and 10 up.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
yup, I've got a couple more things to do for it. Once everythings done ill be moving back to MD5 so I can play with it for a while!

Yes this rom will work fine on your T999.

NO, it will

There is no way your phone will get LTE either. Sorry.

Samsung removed ad hoc mode as most others did in jellybean, we will have to run custom kernels to use wifi tether, after we have a solid base for stock roms in all formats and they are debugged then we can start on kernel mods to add it back in, but I'm positive it will be a huge undertaking, unless someone wants to find a way to port it from a device like my Asus TF300T, which is sure to cause major instability issues, possibly bricks. We will just have to see. The best way would be to try and port it from the Asus TF300T that is still running jb 4.1.2 mine is on 4.2.2 and still has it but I don't know that its going to be compatible with the kernel.

[T-Mobile, Samsung Galaxy SIII] tower_gilead:
My Tethering works fine on a stock rooted t999 rom... it was just that first test build the doc put up where it wouldn't work. I am a Tethering fool and have never received the upsell text but that may be because I try to keep it under 40g per month.

[T-Mobile, Samsung Galaxy SIII] MotoDefier:
It could have been just the moto defy I had but I received it several times until I rooted, stock T999L has ad hoc mode removed and most wifi tethers use it, the es file explorer method works but it enables tmo's stock tethering. So I just thought I would throw it out there, still gonna run tests later to verify yes or no

You need to change the apn that tethering uses in customer xml.

[T-Mobile, Samsung Galaxy SIII] MotoDefier:
Woke up this morning, to find LTE is no longer active, I guess yesrerday was just a test of the system, boo!

Spoke wit tmo this morning, they confirmed that the LTE was a temporary deployment for testing, but did confirm LTE will be fully operational in the DFW market in the next 3 months and further stated that LTE would be fully operational in all 25 major markets by the end of the year, hope the speed I got during their test yesterday is indicative of what its going to be upon the actual deployment.
[T-Mobile, Samsung Galaxy SIII] Slypnslyde:
That makes sense now because I'm in Wilmington Delaware and I say about a month ago I was getting speeds of 25 mbps and now it went back down to about 10-15. I thought maybe it was a certain rom I was using at the time

how to

hi sorry to bother im a newbie here and will like to know how can i flash the stock rom to the t999l because i use motochoper to root and now i get the error of no sim card any help will be appreciated and sorry if i post in the wrong forum....
[T-Mobile, Samsung Galaxy SIII] MotoDefier:
Shutdown, pull battery, pull sim, replace battery, power on, wait for no sim message Shutdown pull battery, reinsert sim, and battery, this should do the trick, if not get a new sim from tmo, I used moto chopper as well and had no problems, if the problem persists then we will talk about flashing the rom, but its not really the best place to start for a noob it does require technical data, software, and nerves of steel, if you do it wrong you get a brick, and no warranty or insurance coverage, unless you hardbrick it beyond repair. Then you can claim a failed boot but I still wouldn't try it unless you are familiar with adb and its functions. Another option you can try if you didn't flash a custom recovery would be to do a factory data reset, if you did then you will need to use the md5 rom posted in the forum to flash back to stock, I know its a lot to take in as a noob but if you can follow directions well, one of us can help you get it back to stock, do you have adb installed on your pc?

Search the forums for your problem as well, this is a rom development thread, so your question is better suited in the q&a section. But I'm sure we can help you, I would ask DocHoliday77 as he has the most experience, here. Try what I said first before anything, you may also find if you log into your wifi that your phone will re register on the network with wifi calling enabled, then turn it off and see if you still get the error.
[T-Mobile, Samsung Galaxy SIII] kiloz:
ok i try that and still no sim card detected, and try to put the sim card in other phone and work so its not the sim card, im running stock recovery, i got adb install in my pc and if you guys guide me i will do whatever it takes... thanks
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Wow! 4 years and only uo to 3 posts so far! That is a rare thing to see!

Just so I'm clear, do you have the T999, or T999L?

Did you attempt to flash or do anything after rooting with motochopper?
[T-Mobile, Samsung Galaxy SIII] kiloz:
T999L and no just root with motochoper and thats about it no sim card detected after that, and i also read about the imei to be erase but in my case mine its showing good imei and baseband ...
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
I would try flashing the PureStock rom to start.

It'll rewrite your system partition but keep root. So if something there is corrupted it should fix it.

You will need to install a recovery first though. Get rom or goo manager from the play store and use it to install recovery. (Rom Manager is CWM. Goo Manager is TWRP. Your choice)

Then from that recovery, flash the rom. If that doesn't fix it, then try flashing the modem.

Everything you need is in the OP and my signature.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Oh, and just curious, in settings, about device, what is the build #?

[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Just got back from fishing so I can explain a little better now.

Download TWRP 2.5.0.0 from my Sig (the one that's in .tar format).

Download Odin 3.0.7 and unzip to an easy to use location. (Mines in its own folder on desktop).

Run Odin, reboot phone to download mode. (Power off, then hold HOME, volume down and power. Then press volume up when asked).

Now with Odin open, plug in your phone and it should say COM ## in top left.

(If not install drivers from my Sig)

Click PDA and select the TWRP you downloaded

Only have F-reset and auto reboot checked.

Click start.

Phone will reboot.

Now reboot recovery and flash PureStock.

Then flash stock recovery.

When done do a factory reset.

Reboot and install Triangle Away.

Reset your flash counter.

Open Superuser and there should be an option to permanently unroot.

Do as it says.

Reboot and verify root is gone.

Reboot download mode and verify counter.

Otherwise, go ahead with the Dr on the partition and I can let you upload it to my acct again. I can pull it apart to see what all its including and try to figure out why is bigger than it should be.
[T-Mobile, Samsung Galaxy SIII] MotoDefier:
Having some issues with the script, told it to look for system.img.ext4 but it keeps throwing the "WARNING: system.img.ext4 does not exist" which is exactly what we want the script to do before packaging the rom, if its not in the extracted folder for the script but it is, I will be reviewing the coding to make sure I didn't code it wrong, but I have checked the coding several times and don't see an error with the script that would cause this behavior.
[T-Mobile, Samsung Galaxy SIII] DJ_SpaRky:

ok i got the phone in pure stock now but when i try to flash recovery its fail for some reason even try odin and its stay like freeze and says recovery stays for long time... what im doing wrong ?
[T-Mobile, Samsung Galaxy SIII] MotoDefier:
If you've got the phone to pure stock you shouldn't have to reflash the stock recovery, it should have overwritten cwm or twrp when you flashed to rom with Odin, have you tried booting into recovery, and what are your results?
[T-Mobile, Samsung Galaxy SIII] kiloz:
the thing heres its that i flash with recovery cwm due to no odin flash available yet to T999L
[T-Mobile, Samsung Galaxy SIII] MotoDefier:
I think doc posted an odin flashable rom in the OP it does have root, but you should be able to unroot with SuperUser.apk as doc said and then check your flash counter after installing triangleaway and booting into download mode
[T-Mobile, Samsung Galaxy SIII] kiloz:
no theres no odin flashable rom yet for the T999L if you know wheres it its let me know...

RECOVERY!!!

Really sorry you had to wait so long on me. I think I may have figured out why it didn't flash and have made 2 new recovery flashable zips for you to try.

First though, you are currently running the PureStock rom from the OP correct? Are you still having the problem with the SIM card? Any other issues? And you are trying to do this in order to make a warranty claim? Sorry bout all the questions!

Anyway, back to the problem at hand.....recovery...

Can you tell me if there was an error when you tried to flash the one in recovery?

If it was related to an 'assert' message, then the V2 file may work. Otherwise, the V3 file will hopefully do the job. (Im kind of expecting V3 to be the one with the best chance of working) Its your choice which you want to try first. Considering that the first attempt did not cause you any additional problems, I believe these to also be safe to try.

If neither of these work, I will walk you through doing it manually.

If you have any questions, feel free to let me know! I will get back to you as soon as I possibly can. (And unless I am asleep, I dont think it would take very long!)

Sorry again that everything took so long! I know it sucks to be stuck like that and not really have a way to fix it!

Here are the Links:

(Remember, these are recovery flashable zips. Flash in CWM or TWRP.)

Awesome!!! So glad to hear it worked! Am still sorry for the trouble though. I don't have the T999L so some stuff I can't test before release, and it seems no one wanted to try it unless they had to. (Don't blame anyone for that!)
