****This will NOT make a

model LTE capable!!! Simply put, it CANNOT happen!!!****​

==========================================================================================================

NOTE

: It is

CONFIRMED

that the T999L modem, does

NOT

work on the original T999. It will not brick the device, but you will have no connectivity.

The same has also been confirmed for the AT&T GS3 - I747. It will almost certainly be exactly the same for ALL variants of the S3!!!!!

==========================================================================================================

The ROM will work on a T999 with few to no problems though! (Ive been running it for about a week now!)​

***See Post #3 for instructions on How to Return to Stock***

As most of you know, T-Mobile has recently released a new version of the Galaxy S3. Unfortunately, it seems that Samsung never releases a downloadable version of their firmware for newly released devices. This seems to be no execption, which means that there is no way to fully return to stock once you have rooted and begun flashing customs ROMs and whatnot. For Example: If you root by flashing CWM or TWRP, your stock recovery is now gone and there is no way to get it back......until now!

Over the past several days, I have been working with Motodefier to solve this issue, and I believe we have done so! What we have is a way for users to return to stock if they so desire.

***********Motodefier and I have decided to delay the Odin version of the firmware for the T999L, just to be safe. There are too many unanswered questions and while I think we have it down and would be ready for use, I do not want anyone flashing it until I am certain it will not brick their phone. We have not given up on it though, and will keep you guys posted. In the meantime, we do have an alternative method using the recovery.

I believe Moto is planning a debloated release soon, so be on the lookout for T999L based custom roms to hopefully start coming out soon.

To all of you T999L owners, please do not expect the devs of current ROMs to release additional builds based on this. Their current releases should be able to work on your device as is anyway. I will put together an MB7 kernel + modules zip that you can flash on top of these ROMs in case any of them do not fully function on your device.

In the end, any T999L builds will most likely come from people who actually own it.

Note

:

I do not have the T999L

, so I unfortunately have to rely on others for testing. Where possible, I will test on my own device and will post the results. I will also be sure to label each item as Untested if it has not been.

I am confident everything will work as intended. I wouldn't release it otherwise. If you do decide to try any of this, please post your results. If there are any issues, I will work to solve them right away.

**If you see an item that is untested and you do flash it, please post your results. If it fails please also PM me and Motodefier for further assistance.

*****In the event of ANY FAILURE :mad:. Send me and Motodefier a PM, and post here so others know. We will make it top priority to get you back to stock and running normally.

***Please see Post #2 for a list of any reported bugs/problems.

Stock Firmware

(NOT WORKING! Link Temporarily Removed) :(

I suggest waiting until the others are tested before testing this one.

This contains the following underlying firmware partitions:

aboot.mbn

NON-HLOS.bin (modem)

rpm.mbn

sbl2.mbn

sbl3.mbn

tz.mbn

Note: Together, these are the equivalent of a Full Firmware as you would normally use if an official one were available. Once each piece has been tested and found working, I will put together a single flashable that will put you back on stock. I will also release a root66 version.

I had posted a couple of these a couple of days ago, but apparently no one wanted to test or no one saw them and they got buried pretty quickly. This is a request for anyone willing to test them out. As usual, I tried my best to make sure they are safe to use. If they do not work, I believe they will fail almost instantly without actually flashing to the device. Also, as usual, i cannot guarantee this, nor that it will not brick your device. This is testing AT YOUR OWN RISK!!!!! Please make sure you have a nandroid backup ready, just in case!

*Please see Post #3 for more information on how to use this to revert back to stock.

T999L UVAMB7 Firmware

(Untested, but the script used as a template has been proven)

**Thanks to Aerowinder for the use of his script for this!

DOWNLOAD

*This is the underlying firmware that you would find in a full Odin flashable, stock firmware package.

*Includes the following:

aboot - Apps Boot

modem - Baseband/Modem/Radio

rpm - Resource & Power Management

sbl2 - Secondary Bootloader 2

sbl3 - Secondary Bootloader 3

Stock Kernels

**The kernels with the '+' at the end will uninstall any 3rd party items that may have been flashed along with the kernel (i.e. ktoonsez's Kernel Tweaker App, modules, etc.) They also include the modules needed for everything to work properly using a Touchwiz build and kernel.

**Thanks to enewman17 for the script used to accomplish this!

If you see Motodefier, please remember to hit his Thanks button! Without him, this wasnt possible. He put in a lot of time and effort in all of it and more importantly, he took ALL the risk while experimenting and learning about the device!

I hope this proves helpful to some of you!

:cool: Huge Thanks to all who are participating in this project, especially those of you who have been willing to test everything for us! :highfive:
