I do need to update a few things, but use the official root66 firmware instead

Also, you may just need to factory reset so try that first.

T999N Kernel

Here is the Stock Kernel plus Modules from the T999N. I will add it in the OP's when I am updating them. This is mostly for those with the T999N but I can confirm it works on the T999, and expect it to work just fine on the T999L as well. This is another option for you guys with camera issues on stock based roms.

[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
And a note to the T999N users, I did finally get a /system pull, but am having issues with creating a working rom. If anyone is willing, I would like to get another pull from someone in case something is corrupt in the one I have. If you are interested, shoot me a PM and I will walk you through it. Its pretty easy to be honest. If you already have the Android SDK and ADB installed on your computer it is a plus.

Thanks
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
OP Updated!!!

Updated OP1! Updated FaQ and other information to more current understandings and to include the T999N.

More updates to come for the rest of the OP's!

Let me know if you think I missed anything.
[T-Mobile, Samsung Galaxy SIII] exaqtion:
I tried a factory reset and it was a no go. Even when I tried a new roms my phone wouldnt get no reception now, just roaming. I went to mobile networks and the only thing that popped up was an "imei" screen. I tried to connect with Kies also and the program wouldn't detect it. I did both the cwm flashing way and Odin. I will try the root66 way as soon as I can.

Update: I flashed the CWM10 rom on my phone and went into the mobile network and the network mode is stuck on CDMA. I try to change it but it wont.

I'm guessing i need to restore my IMEI? I checked it and it came up all 0s.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Odin flash back to stock. If it still has an IMEI of 0, pm me to let me know and I can help. Did you not run the NV backup?
[T-Mobile, Samsung Galaxy SIII] exaqtion:
Currently at work. I will Odin flash back to stock again when I get home. I did run the nvbackup...thats the terminal > su> reboot nvbackup ...right? On cwm mod 10 it just says roaming but when I got back to stock (following your method) I get the android.phone stopped working pop up nonstop or the "no sim card"/ "no service" message. Sim card works perfect in my Sony Ion. Do I need to triangle away first? My toll is up to around 18 right now. Btw i really appreciate the help. If you could guide me to getting the phone back I could spare some change to you via paypal.

Would imei = 00000 also indicate a blacklisted phone? I bought the phone from craigslist and i was using it for a day with no problems before I tried the odin back to flash. I checked the free sites to see if the imei was blacklisted and it stated no.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Ok, in response to your PM, use the root66 firmware, not the stock system. (Either would probably be fine, but I'd rather use the full firmware just to be sure.) Factory reset after using Odin. This will wipe your internal sdcard, so back it up first if needed.

Is the Rom you are on one of the 4.3 roms? If so, this happens often apparently. Try rebooting several times to see if the imei comes back. Usually it's not gone, just these 4.3 builds are very buggy and have issues reading the nv data it seems. If that doesn't solve, go ahead with the Odin flash of root66 firmware. This also usually brings it back if you were on a 4.3 Rom.

If your imei is still zero, then that is very strange, and is the first I've ever heard of it being lost by anyone who has done the nvbackup.

Once back on stock, you can also try to use the nvrestore command.

su

reboot nvrestore

If that still doesn't help then pm me again to let me know and we will have to restore it manually.

If you're blacklisted, it won't change the imei. The network just uses it to identify the device. If it were blacklisted, it simply just wouldn't connect. Nothing would change on the device itself.

T999n lost 4g

Hey there

! First off thanks so much for all the contributions made to this forum it has helped me many a time and usually things work great. However, I have a T-999N on MetroPCS service which I just rooted using the Odin method described in thread, and used the linked file titled "Stock System + Root___VERSION 2!" The phone came back great and with root but I have lost 4g connectivity and am wondering if this is due to a mistake on my part or if there is a step I have yet to complete.

Is it possibly because the build I flashed was UVAMB7, and not UVAME4 like this phone comes stock with? I could not find a t999N specific file and from what I gathered things should work the same on both models? In about phone, the baseband version still shows t999nuvame4, but the phone thinks it's a T999L now and boots up with T-mobile animations. Any help would be greatly appreciated! Thanks!
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Either of those two modems, ME4 and MB7 have been verified to work fine on both models. And they aren't dependant on the build of the Rom, so a mismatch between the two shouldn't matter.

I'm not sure why it would be doing that other than the two most common causes, missing imei, or network problems on your carriers end.

It's always a good idea to call and ask first, otherwise you could end up spending your time and possibly others hunting for a non existent problem.

the one thing here that I'm uncertain of is how you flashed. No one's ever flashed that T999L system image to a T999N with odin that I'm aware of. I'd guess it's ok as it should be like flashing a Rom, but I never recommend using Odin to flash anything not specifically stated to work on a given device. It's a quick way to brick.

Anyway, I can't think of anything that you did that would break 4g, unless the imei was lost.
[T-Mobile, Samsung Galaxy SIII] KAsp3rd:
Sounds like it could be a missing apn issue. go to settings > mobile data > apns

Under the T-Mobile APN change the following

apn="fast.metropcs.com"
mmsc="http://metropcs.mmsmvno.com/mms/wapenc"
[T-Mobile, Samsung Galaxy SIII] mrrexsocks:
T999N

Thank you so much for the replys,

The APN settings did the trick and connection has returned. LTE and 4G HSPA are both working normally and I have root privilege.

All and all, I should have read more thoroughly and realized the FW that I grabbed was only for the T999L, However, the good news seems to be that at least in my case, the stock rooted T999L firmware build UVAMB7 is working great and I have successful root access on a T999N, and there seems to be no loss of functionability. I appreciate your help and will be checking back for updates on this model.

Thanks again.

[T-Mobile, Samsung Galaxy SIII] DocHoliday77:

Official T999N firmware has been released!

Download from me if you don't want to deal with hotfiles slow slow slow speeds! I'll add to my firmware thread and the OP later on. Also have sent a request for a root66 version.

Here's my link. I'll be uploading that Rom I promised as soon as I get home.

http://www.androidfilehost.com/?fid=23159073880937022
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Ok, finally got it uploaded! This is a rom built from the T999V firmware build UVDMF2. It does not have any of the T-mobile bloat and apps, and it has a larger language selection than the T999 firmware. It does not have T-Mobiles WiFi Calling though, so if you depend on this, you may want to think twice about flashing. Or perhaps someone with more time than me can try to marry the best of both together in a way.

The rom seems to be stable and functions well on my T999. It does include the MF2 kernel. It should work for the T999L as well. I cannot guarantee there wont be some issues with things like the camera again. The only way to know though, is for someone with the T999L to give it a shot.

Make a full nandroid backup of your current setup before doing anything. This way you can easily restore if necessary.

I think that should cover everything. So here is the link. Let me know if you have any questions.

[T-Mobile, Samsung Galaxy SIII] Perseus:
I always thought, wi-fi calling APK is all you needed provided you have official stock rom.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Nope, like everything else it's tied into the framework. In addition to any supporting libs and other files, you'd need the Settings, SystemUI, and probably other framework apk and jar files.

roaming not working

Just need to know I have been rooting devices for some time now and I really haven't ever traveled out of tmobile service area but now I have been lately and I cant seem to get roaming to work on my device. I called customer service and they said I should be able to roam on my unlimited everything account. I have followed all settings to get the device to connect to att but it always says cant not connect to att at this time try later. Now my question is does being rooted have something to do with me not being able to roam domestic.?
[T-Mobile, Samsung Galaxy SIII] Perseus:
Nope don't think so. Can you specify your device (SGH-T999 or T999L or something else) As well as your Current Rom (Rooted Stock or custom)
[T-Mobile, Samsung Galaxy SIII] beachbum40:
my device is gs3 T999L im running the jedi academy rom but tried both stock rooted for our t999L and custom and im still unable to roam domestic.
[T-Mobile, Samsung Galaxy SIII] Perseus:
Ok. Please Odin back to Stock. Make sure the modem is one from OP of this thread. After that is done, change the APN to Fast.T-mobile.com. Once that is done, please let me know.

Are you absolutely sure Jedi Academy is available for SGH_T999L ? A quick Search shows its for NOTE II
[T-Mobile, Samsung Galaxy SIII] beachbum40:
I did the odin back to stock and made sure modem was correct apn settings where fast.t-mobile.com but no go still no roaming. Too the other question yes I am using jedi academy rom here is the link great romhttp://xdaforums.com/showthread.php?t=2412786
[T-Mobile, Samsung Galaxy SIII] Perseus:
That's a SGH-T999 Rom. If it is tested for SGH-T999L then yes use it. If not then that could be one of the reasons. Ask on that thread if needed.

Have you turned on the 2 settings under Settings > Data for Roaming ?
[T-Mobile, Samsung Galaxy SIII] beachbum40:
Yea I flashed the d2tmo recovery for T999 and now im able to flash all most of the t999 rom with no issues. Can u plz be more Pacific on the settings in data roaming? Data roaming is set to all networks as of now. I dont think by flashing a custom rom would affect you device from getting to roam. As long ad modem and radios are right which I haven't changed any of those they are still stockT999L UVAMB7
[T-Mobile, Samsung Galaxy SIII] Perseus:
You are right flashing custom rom won't change the modem. It shouldn't also affect the ability to roam.

The 2 Settings for Roaming are in Settings > More > Mobile Networks. There are 2. Data Roaming and National Data Roaming. Check them both if not done already.
[T-Mobile, Samsung Galaxy SIII] beachbum40:
I do have those checked well theres a data roaming I click on that and it says disable or national data roaming or all networks so I clicked on national data roaming. I also so use a app called sim toolkit and it is saying data roaming is on but voice roaming is not. If im not mistaking when roaming on tmobiles pre paid unlimited plane you only can get voice roaming that meaning you can make and receive calls and text but you dont have access to data or web. Im going to take my phoneup to tmobile store ttomorrow and see whats up cause I had a lg optimus through tmobile and I didn't have these issues it would connect auto maticly
[T-Mobile, Samsung Galaxy SIII] Perseus:
Oh you are on Pre-paid. I assumed post-paid. Yes you are right, on prepaid there's no Data Roaming.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
When you are at the store, see if they will give you a new SIM card, just in case that's the problem.

post pay

I went ahead and switched my pre paid service over to post paid tmobile unlimited talk text and 2.5g of data now im hoping this solves my voice and data roaming issue. Just worried that since my phone was originally a pre paid device and now im on post pay that the firmware will be configured correctly to use data and voice roaming. All they did at tmobile store was replace my sim card to put me on a post payed account. They said I should be able to get roaming to work now. They didn't need to do any flashing just a sim swop
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Don't worry, they don't configure the phones for pre or post paid. They should all be the same.

??? pre-paid t-mobile T999L

hay when i try to flash roms to my t999l it always gets stuck looping on the android is upgrading it counts out the apps shows the welcome screen then like 5 seconds later it does the android is upgrading thing again then it starts doing it over and over no mater what recovery i use or what i wipe dont wipe flash dont or what modem i use seems to me there is only one modem

could it have a locked bootloader or network lock if so any tips on how to fix this
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
No, its bootloader is not locked. Only the one T999L and one T999N modems are available for you to use.

Helps to know what Roms you are flashing, what recovery, where downloaded, exact steps you take when flashing, etc.
[T-Mobile, Samsung Galaxy SIII] laniclamoore:
i have been using both CWM and TWRP (cwm 6.0.3.1) (twrp 2.3.x) the roms i have tried using are "toasted marshmellow" 4.1.2

and the MIUI for t-mobile t999+t999L

i did edit the asserts on both and removed the certs also but it did not matter

the only one i can get to work is CM 4.3 os but it screws the storage partions up and will not mount sdcard or external sdcard correctly

p.s its a 64gig sdcard
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
For your initial problem, I'm not too sure. Odin flash the stock/root66 firmware, factory reset, and try again. If that doesn't help them I really don't know how to solve that one....

For the sdcard, plug it in your computer and format as fat32 if you are using any non touchwiz Rom. ExFat should be fine on touchwiz though.

And afaik, all 4.3 roms will have the /0/0/0/ folders issue.
[T-Mobile, Samsung Galaxy SIII] SamsungAllDay:
Hey Doc, I'm running dirty unicorns 4.3.1 on my T999L. My problem is my camera isn't working which I know you covered in this thread but, I went through 22 pages and tried everything you suggested so far and nothing seemed to work. Lol I got tired of reading this so this is me asking you what else should I try? I tried 3 kernels and none of them worked.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Other than trial and error, I'm not sure. You may want to ask the dev of your Rom. May need a combination of kernel, cameradata, modules, lib, bin, etc.....

Basically the Rom you are using doesn't have one or more of needed files. Plus it's a 4.3 Rom which, from everything I've heard, are not very good all around daily drivers. Many should probably be considered beta, especially considering the problems they have with the NV data.

I suggest using a different Rom, preferably one built from an older, more stable base. (Not knocking anyone's work btw. Seems that the 4.3 aosp/cm roms are just still kinda buggy before they even get started)

I personally never use cm/AOSP. So this also means I am not the guy to ask about Rom specific issues on those. Sorry I don't have a better answer for you.
[T-Mobile, Samsung Galaxy SIII] SamsungAllDay:
What ROMs would you recommend for the T999L because All the other ROMs I've tried Faial during flashing.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
You'll have to judge from others reports in this thread. I don't have the T999L and haven't run a released Rom in quite a while now. Pretty sure people have said Wicked, s3rx, nandroid, etc are all good ones.
[T-Mobile, Samsung Galaxy SIII] Adreaver:

Didnt get data to work on T999L weird cause when I checked status it said network tmobile and in service but when I went into mobile network it said insert sim. There was no 4g icon. Hmmm.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Just saw another thread where someone wants all the devs to update all their threads to say if they built their Rom for the T999L and assuming that there are roms there that will brick the device!

Please search and read! None of the roms there will brick your phone!!! Read this thread and follow instructions and you will be fine!

Use the T999 recoveries and many will flash! If they don't just edit the updater-script yourself. But do not expect a Rom dev to do something like this just to accommodate you! Be polite and ask them to add it in their future updates. If you read though, this is nothing you can't easily do yourself.

As has been stated many, many times already, you can flash any T999 recovery, kernel and Rom. Just stay away from anything else!

Yes you may need to do another tweak here and there, maybe not, but it won't brick! (If it does it likely is not the roms fault)
[T-Mobile, Samsung Galaxy SIII] laniclamoore:
wow I hear a little Animosity! I shall ease thy assumptions!

Please for all that missed my meaning....

I IN NO WAY IMPLIED THAT THE ROM DEVELOPERS should do all the work I simply stated

They need to clearly label what s3 its made for and mention in the install instructions that the person that's going to use the rom needs to modify the updater.script to correct the asserts before hand

Becuse I personaly like to keep thing short sweet and simple that way everyone is learning and contributing to the Trans-mogrification of ANDROID MWAAHAHAHAHA!!!!!!! sorry to anyone that took

Offense to my thread

SIGNED BY CAPTAIN. LANIC LAMOORE AKA the bearded man
[T-Mobile, Samsung Galaxy SIII] Perseus:
That's the fundamental point. The developers have a lot of expectations riding on them. Not to mention technical challenges to OS upgrades. I wouldn't expect such tiddly bits on them. It is this reason, most of the Rom developers have not been active here on XDA.

Take Slim Rom for Example. Its coded for ATT S3 I747. Yes my Phone T999 will report as I747 after I flash the rom. Yes some places that causes issues. So all I need to do is go to Build.prop and edit one or two places. Its not such a big deal and I do it automatically by now.

Removing Asserts from the Updater script is not the developer's responsibility. The Asserts are there so that other devices like S2 or S4 don't accidentally flash this rom and softbrick their phone.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
No offense taken. It's just this has been brought up several times in the past and it seems like some expect the devs to cater to their specific needs. This already happens too much to begin with, without including the requests to mod their scripts and Op's.

I know it's a bit of a hassle for some of the roms that have not been updated, but as they are, the T999L does get included by most. With a new build about to come out there will be a bunch of new and updated roms and this will virtually become a non issue on it own.

For those who got a different device than what the devs originally built these roms for, it does take a little extra work. But that's one of the primary reasons for this thread, to empower users to be able to do this on their own and not put the extra work on the devs. As time goes on, and they update their roms it needs to be done less and less. We have already seen improvements in this area. Most all new releases do include the T999L now. But if it doesn't say so then just assume they haven't.

You guys had also mentioned protecting people from bricking their devices. I also just wanted to reiterate that this is not any more a danger for the T999L than it is for the T999. The partition layouts are the same, so if it can flash to one, it can flash to the other. Full functionality may or may not be an issue, but there isn't any extra danger of a brick.

And I'm not trying to be argumentative with you btw. I've just addressed this several times before and wanted to do so quickly so newer users don't start asking all the same stuff over and over again. It does get a little tiresome to have to 're-explain it for each one.

[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
currently, the OP consists of the first 4 or 5 posts. Too many people will read the first post and stop. Then they ask a question thats already covered and if i tell them to read the OP, they claim they already did. So ive started referring to them as OP# hoping folks will figure out on their own that an OP is not always limited to just post 1. If i know an answer is in the 3rd post ill just say check OP3, for example.

In your first post you said you looked everywhere but couldnt find a guide, but the guide is in post 2, OP2 if im not mistaken. You didnt mention that you tried anything so all i could do was urge you to read the entire OP.

If theres an issue with my cwm file, i do apologize. no one else has reported the same though. which version were you downloading? Did the md5 on the download page match the downloaded file? Did you try the second to newest version?

Ill look at it myself once you fill me in a little more. But for now try one version older.
