[Stock][ROM]Galaxy S3-LTE (d2ltetmo)

Thread Purpose

To help new T999L and T999N owners get started on discovering the full potential of their new device.

To assist members with troubleshooting and provide general help and information for the device.

To answer the most frequently asked questions about the T999N, T999L and LTE.

Note

: While this will be primarily focused on the T999L,

nearly ALL information will be directly applicable to the T999N

as the devices are identical. Only the firmware is different. I will try to state specifically anywhere there is a difference. But if it is not stated as such, it is fairly safe to assume the information in question is relevant, as is, for both devices.

There will also certainly be information here that can be helpful to everyone. I invite comments and suggestions from all of you!

I am aware that there is a good deal of confusion out there about these latest versions of the S3. I hope to help alleviate that confusion by consolidating available information here. My goal is to provide you with everything you need in order to get what you want out of your device (well almost everything!! :cool:)

Be aware that I plan to organize this over the first several posts, so please read everything before posting questions and/or new threads.

What this thread IS NOT

A place to continue the debate about the T999 being LTE capable.

A place to complain about T-Mobile telling you that the T999 will get LTE.

A place to find support for the OLD MetroPCS model, SCH-R530. (I think thats the correct model)

FAQ

Here is a somewhat rough draft of some of our most frequently asked questions. I will add, edit, revamp, make better as we go. If you notice a popular question that I left out, let me know so I can add it! I just wanted to get them out asap as I felt I have waited long enough!

Why Can't I Get LTE?

That depends:

Are you certain you have an LTE capable device? Namely the SGH-T999L?

Are you sure that LTE is available in your area?

Did you pay your bill on time?

It is also highly possible that there are currently network/tower problems in your area. Call T-Mobile Support and ask.

Check your IMEI number. If it is zero, PM me!

My ROM doesnt show LTE in the statusbar, only 4G.

If you have flashed a custom rom, you may be getting LTE only it does not know how to display this in the status bar.

To tell what your connection is for sure, start a download (your next rom is a good one), then go to Settings > About Device > Status > Network Type

Why does my phone say it is a T999?

Because you flashed a rom that was based on or intended for the original T999 model. This is perfectly normal.

If you really want to change it, go to /system/build.prop and edit all lines that say SGH-T999, to your model or whatever you like.

(WARNING!!!) If you change this to a different model than the T999 or T999L, some apps may think they are on that different model device. This can cause a brick if you try to flash firmware with Mobile Odin. Other apps may not function as intended. Use Caution!

Can I flash ROMs from the T999?

In short, YES

BUT....some ROM's will not flash without a little intervention, so to speak. If you get a Status 7 error and the ROM will not flash, this is what you do:

Unzip the Rom.

In the Meta-Inf folder, delete the signatures (CERT.RSA, CERT.SF, MANIFEST.MF)

Browse to META-INF\com\google\android\ and open the updater-script in Notepad++

At the top of the script, there will be one or several lines beginning with "Assert". Delete these Lines. Save the updater-script.

Re-Zip the Rom and try again to flash.

Can I update my bootloader so I can Flash CM?

NO. AND DO NOT ATTEMPT TO DO SO!!! YOU WILL BRICK YOUR DEVICE!!!!

See the question above about removing the "Assert" lines from the Rom's updater-script to make the rom flashable.

Can I Network/Carrier unlock via the free method posted in General?

Unfortunately, this is not possible on 4.1.2 as Samsung patched against it in this build. Because there is no earlier firmware for the device, you cannot downgrade like people can with the original T999.

Your only options are to try to get the unlock code from T-Mobile, or pay for the service from an online retailer. You can find some on ebay, or just by a google search.

Can I flash another radio?

YES.

The T999 and T999V modems will flash, but you will have no connectivity. So do not flash these. There is no point.

However, as of right now you can only use two modems. UVAMB7 from the T999L, and UVAME4 from the T999N are interchangeable. Meaning you can use the T999N modem on the T999L, and vice versa. Please read my Modem/Baseband thread for downloads and more information on modems. (Link is in my sig)

Can I flash any of the firmware that is for the T999 or T999V?

NO! YOU WILL HARD-BRICK YOUR DEVICE!!!!

ONLY flash T999L firmware to a T999L and T999N firmware to a T999N!!!!

If it does not match your model EXACTLY, it will almost certainly brick your device!!!

Can I flash the T999L firmware to my T999N, or vice versa?

NO! This is one of the areas where the two are NOT compatible!

ONLY flash T999L firmware to a T999L and T999N firmware to a T999N!!!!

If it does not match your model EXACTLY, it will almost certainly brick your device!!!

What is safe to flash to the T999L?

You can safely flash any of the Roms, Kernels and Recoveries found here in the T-Mobile GS3 forum.

You should also be able to flash any of the mods available, but unless you are on a matching firmware build, YMMV.

Flashing T999/T999V modems shouldn't harm the phone, but they will not work.

Why wont my camera work after I flashed CM?

This is a known issue reported by several people on several roms. It seems the fixes are different for some roms, and one or two have no solution as of right now. The most likely cause is a Kernel/Module mismatch. (for example, if you flashed a T999 based rom, but kept your T999L kernel, it will not work as the kernel cannot work with the T999 modules.) In this case, the fix is simple, flash any of the kernel plus modules I have made available. This will flash the kernel, plus its compatible modules and should solve the camera issue. Some have reported this being fixed by flashing the ktoonsez kernel (it includes its own modules).

In the cases where this does not solve the issue, it may be due to an incorrect module, lib, framework, cameradata, kernel, or any combination of those or possibly something else we have not found yet.

Why is my WiFi and/or Bluetooth not working after flashing a T999 based Rom?

Most likely this is also due to a kernel/module mismatch. Try flashing one of the kernel plus moudles I have available.

Let me know if you think of any other questions I should add here! Thanks!
