root66 for new firmware

Will the root66 work for my T999L with baseband T999LUVUBNC1?

I know this is an opinionated question, but what is considered the best available ROM for this phone (most useful or most used)?

Thank you
[T-Mobile, Samsung Galaxy SIII] Drashnar:
Yes. I also have a T999L and ran the root66 image for awhile before moving over to CM11. All relevant information and links are in Doc's sig. Just make sure you have backups and make sure all the numbers (model & versions, etc) match up before you do any flashing. Any other problems, there are several people here that will answer questions if you have them.

As for "best availible" rom, as you say it's a very subjective question. I'm partial to Cyanogenmod, but then again I've used them for a long time too. Everyone likes different things, so your best bet is to research then try one out.
[T-Mobile, Samsung Galaxy SIII] daggorlad:
recommending a particular ROM is prohibited on XDA. The only thing we can tell you is to choose a flavor (AOSP/TW) then read up on the description of each one and try until you find one you like. If you want a more stable build I would suggest a TW ROM. If you want more customization and more debloated, then go with AOSP. Personally, I like "some" of the bloatware and stability, so I am using a 4.4 TW port. But I am somewhat of a flashaholic. :p
[T-Mobile, Samsung Galaxy SIII] Perseus:
Yes so long you choose from 2 listed in #4.

For the rest of your question, see bellow.

Personally I support SlimRom an AOSP Rom for the US variants of S3. So I use what I develop. :p

Baseband version T999LUVUBNF4 for SGH T999l

I just read on the T- Mobile site about a new update, here is the quote;

( Beginning July 17, the Samsung Galaxy S III LTE (T999L) will have a software update to Android version 4.3/ Software T999LUVUBNF4 via manual pull down or Kies. This update only includes backend fixes. This software update only impacts the Samsung Galaxy S III LTE t999L.)

I have the SGH t999l Android version 4.3/Baseband version T999LUVUBNC1. I have used the Root66 method on it.My question is do i have to revert back to complete stock to apply this update and if i do can i again use the Root66 method again on the new update with Baseband version T999LUVUBNF4? I am not sure if this is the right place to ask about this so if not can someone direct me to the right place or give me some advice. Thanks
[T-Mobile, Samsung Galaxy SIII] Perseus:
It is advisable to go back to stock.

You'd need a Root66 Version of that update in order to apply on top of that update. Just to make sure nothing untoward happens.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Hou wont be able to use root66 since there isnt one for that build. There isnt even any firmwate for it at all. Use Towelroot.

Most likely, using an older modem just wont work. Bit if you downgrade your bootloader as well it will hard brick. Once you update there's no going back.
[T-Mobile, Samsung Galaxy SIII] SkylerWallace:
I have a SGH-T999L running 4.3. I rooted with TowelRoot then inf installed SuperSu which offered to deKnox the phone. Not sure if it worked but Root Checker says I have root access. I have Odin set up 100% and used that to flash twrp-2.7.x.tar and it passed the phone after about 2 minutes. It is worth noting the phone booted within the last 20 secs of the flashing operation. I powered off the phone and held VolUp, Home, and Power. I will see Cid (CMs mascot) flash on the screen with text that seems to say "Samsung Galaxy S3" then the phone will reboot normally. I'm used to rooting and not having issues like this. What's going on?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Several T999L users have had problems with twrp recently. Try cwm or philz recoveries.
[T-Mobile, Samsung Galaxy SIII] SkylerWallace:
I'm quite partial to TWRP but I'll try out CWM. Can I use ROM Manager?

Is my situation different than those that you have heard before?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Some couldnt boot, some couldnt flash, some couldnt mount or even detect the sd card. All i know for sure is it seems centered around recent T999L models. I believe it has to do with the hardware revision.

Dont see why you couldnt use it. But imo itd be better to go manual so you can choose the d2tmo recovery. Itll be more compatible with more roms. (They may not even have one specific to the T999L)
[T-Mobile, Samsung Galaxy SIII] :
Well the hardware rev on mine is .4, and I can't tell if that's new, Philz CWM works perfectly. TWRP is kinda iffy. I like TWRP too, its just that also after a hard reboot (phone froze) the recovery would boot but I couldn't do anything. After a few seconds, the phone rebooted again to Android. Might just be me. (And this has happened multiple times.)
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
It seems to only be on newer T999L's from what i can tell. And they had similar problems in the Sprint forums if i remember right. [MENTION=4645794]CNexus[/MENTION] figured it out over there. He might be able to tell us if i am on the right track or not. If i am, i can probably try to tackle it next week if no one else wants to first.
[T-Mobile, Samsung Galaxy SIII] Perseus:
TWRP as yet does not support F2FS. Could that be the issue ? Use Diskinfo app to find out your partition type.

Out of Curiosity, how come you have Airplane mode and Wireless working together ?
[T-Mobile, Samsung Galaxy SIII] :
I didn't. Being able to use wifi and airplane mode has been a feature since 2.1? I used it on my Tmo Vibrant.
[T-Mobile, Samsung Galaxy SIII] Perseus:
Not to my knowledge. Airplane is Airplane. Every thing Kaput.
[T-Mobile, Samsung Galaxy SIII] serio22:
Wifi In airplane mode has always worked for me too.. Even in my iPhone days :0
[T-Mobile, Samsung Galaxy SIII] :
Also, I don't know what F2FS is. Airplane mode + wifi is even on 4.4. I have 4.0.4 (signature)...Anyways, it seems TWRP had just started freezing on boot. CWM doesn't. Maybe it is a bug.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Theres an entry in feature.xml for that.

Airplane wifi dependency. Set to false you can use wifi with airplane mode on.

I think in older builds it may have been something like

Allow wifi with airplane mode

Or something like that.

I have a tmo t999 and was thinking of using the t999n modem on it

If I were to do this would I be able to use the t999 on metro pcs

The t999 was unlocked from a thread on here
[T-Mobile, Samsung Galaxy SIII] :
If its already unlocked, just pop in a Metro SIM. Don't flash the N modem, you'll have no service.
[T-Mobile, Samsung Galaxy SIII] theshadower10:
Metro t999n

i have a friend that asked me to root his phone and it seems that this method is not working anymore??? i got through the whole process and it finished with a "PASS". although when i check the phone after loading there is no SU app installed and also the binary was not there (according to installing super su app from the market). any help would be greatly appreciated since i need to give back phone tomorrow.
[T-Mobile, Samsung Galaxy SIII] serio22:
Make sure you didn't accidentally flash the official firmware instead of root66.. You can also try towelroot
[T-Mobile, Samsung Galaxy SIII] theshadower10:
lol

sadly enough i cant believe i accualy did install the official :silly: will try again and look closer this time :cyclops:

EDIT: i tried towelroot and it worked now i just got to upgrade the su binary :P

EDIT:EDIT: .....hmmm....now it says that i have no binary again after reboot.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Did you update the binary before rebooting?
[T-Mobile, Samsung Galaxy SIII] Satenru:
I have a T999L that's currently running 4.1.2. I've been trying to flash the 4.1.1 modem for a T999 on there with Odin but it keeps failing. I know the reason for that is because of the different models. I've looked at a few different threads and tried a couple other methods like flashing through CWM or using the Sonic Team model flasher but I still can't get to the Service Mode menu. Can someone tell me give me some advice? I'm just trying to get it to a point where I can do a SIM unlock on my T999L. Thank you.
[T-Mobile, Samsung Galaxy SIII] Perseus:
I don't believe there is a 4.1.1 modem for T999L. any further such attempts will not only fail but will result in Brick. You are better off asking T-Mo for the Code or buy it on Ebay. I will go with T-Mobile as they are the most lenient of the 4.
[T-Mobile, Samsung Galaxy SIII] Satenru:
I read some earlier posts in this thread that people were able to do it after rooting their phone. I think I will try again with different 4.1.1 modem and see if I can get any results. I just know flashing a T999 modem on the T999L will disable the network but I can flash it back to stock once everything is done.
[T-Mobile, Samsung Galaxy SIII] serio22:
Sorry but I think you read wrong.. That will only work if you have a T999 on 4.1.2
[T-Mobile, Samsung Galaxy SIII] Satenru:
Well flashing the T999 4.1.1 modem did worked but Service Mode was blank and my IMEI became nulll. After I flashed back the T999L 4.1.2 modem, everything went back to normal. I decided to give RegionLockAway a try and my phone is now unlocked. I should've just went with that option in the first place to save myself the hours and hours of trying to figure out something else.
[T-Mobile, Samsung Galaxy SIII] :
RegionLockAway is for Note 3 though...
[T-Mobile, Samsung Galaxy SIII] Satenru:
Yes I know it says it's for Note 3 but I've used it successfully to unlock 2 Galaxy S4 and this one S3. I think it works as long as as you're using the right modem. If you don't believe me, you can try it your self. Version 4.1.1 and 4.1.2 will work on S3 and 4.2.2 will work on S4.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
It was confirmed a while back to work on 4.1.2, but not 4.3+. I cant believe I had forgotten about that. Sorry for not mentioning it!

RegionLock Away actually works on a number of Samsung models. I think they need to be GSM and might need to be Qualcomm based too.
[T-Mobile, Samsung Galaxy SIII] serio22:
Oddly enough, it works on the S4 with 4.3, even with KitKat if you downgrade the modem.. I saw someone say it didn't work with a T999L but i think it was 4.3.. Maybe if people with 4.3 downgrade modem to a 4.1.2 and run regionlock away it may work
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Definitely worth a try if anyone cares to give it a go. That might mean the same could be done on the T999 and I747 too....provided it works.
[T-Mobile, Samsung Galaxy SIII] :
Oh you need TW. :(

If I can get myself on 4.1.2 and run RegionLock Away I have a MetroPCS SIM I can try
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
If you're really wanting to try it you can use Mobile Odin to flash the 4.1.2 firmware. It can only flash system, kernel, recovery and modem, so it won't brick because you're trying to downgrade. Its not able to flash the boot loaders.
[T-Mobile, Samsung Galaxy SIII] Perseus:
It does not seem to be able to read your CSC folder under /system. That is if one exists. Please see

http://www.droidviews.com/how-to-en...s-on-samsung-galaxy-devices-with-root-access/

Does anyone know if there is a better Download Mirror for this custom rom? im kinda new to this and ive been searching for a few days for a rom the will work with T999L but cant seem to find one.
[T-Mobile, Samsung Galaxy SIII] chalky7880:
As far as I know you can flash any of the roms in this section to the t999l. I have one and I've tried just about all of them. Any rom that's for the t999 will also work for the t999l.
[T-Mobile, Samsung Galaxy SIII] Perseus:
That host has several alternate link where the download is shared. Try one of those links. AFH does get targetted by hackers. So if unavailable, try again later.

Stock Android

T-Mobile Galaxy S3 LTE SGH-T999L

Hi there. I just want to flash the latest version of stock Android (L if possible, KitKat otherwise). The Google Now launcher isn't enough; I want the improved performance and efficiency and I want all the useless Samsung apps off my phone. After I root my phone, where do I get a simple stock ROM? All I can seem to find are custom ROMs with all kinds of mods. I just want stock Android or a very lightly-modified alternative. As far as I can tell right now the closest ROM would be CM.

Thanks.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Everything available for the T999 and variants are in development and original development sections. No idea if an L version is even being worked on tbh. Haven't looked in quite some time.
[T-Mobile, Samsung Galaxy SIII] Perseus:
By simple Android, do you mean something like what Google Play Edition of other devices have ? Or do you want something that looks like Stock Samsung Rom just not the bloat ?

If its former (Google Play Edition like.) Its called Android Open Source Project or AOSP for short. If its latter samsung Rom minus Bloat then its called Touchwiz or TW for short. And then there is Android Open Kang Project AOKP.

There are both AOSP Roms and TW Roms at

http://xdaforums.com/galaxy-s3-t-mobile#romList

Each thread would tell you nature of the Rom (AOSP and TW) and its screenshots. You can give it a try.

Yes L is being worked on. Its going to take some time.

T999L, 4.4 custom rom now or wait for L?

I have t999l rooted stock 4.3. Everything works, a little laggy but tolerable. Maybe because i have a lot of apps, still 5-6GB free internal memory. Maybe needs better RAM management. It shows ~1.5GB total RAM. Phone has 2GB. I wanted to try 4.4-based custom rom, but none seems to be 100% functional when i checked recently. Any rumors if t999l is getting L or will devs work on L-based custom roms soon or in the near future?

Please help Newbie with T-Mobiles Galaxy S3 SGH-T999L Newest build

Please forgive me if I've over looked any other post about this. I am definitely, a complete infant when it come to phones. I did manage to root a Motorola Atrix 2 (MB865) which I paid to have unlocked from AT&T. I never did anything to the phone other than root it; didn't know what to do after that. I did install Titanium Backup, Superuser, and froze some apps but that's it.

I now have a T-Mobile Samsung Galaxy S3 Lte SGH-T999L with Android Version 4.3; Baseband Version: T999LUVUBNF4;

Build Number: JSS15J.T999LUVUBNF4.

I would love to root this phone, install mods, kernels,etc. but the main thing I'm worried about first is removing bloatware and apps that I don't use but I cant find anything recent that shows how to root, remove bloatware,etc.on a Galaxy S3 Lte with this newer Build Number.

Please, if there is anyone that can point me in the right direction, give me a step-by-step.....I don't know how to downgrade a phone to stock (whatever that means,maybe the way the phone came out of the box???) I want to learn badly and I know every phone is different but I can't afford to mess up the only two phones I have; especially the Galaxy S3 LTE. I would greatly appreciate ANY HELP just remember, I don't know much of anything at all. I can take and read directions...might have to read them more than once but what the hell.

CM Camera Fix

Hey, sorry it took me so long to get the cameradata zip for you. Did you still need it?

[MENTION=535343]all[/MENTION]

There have been several reports of the camera not working on some CM roms. I am not certain this will fix it, but if you run into this problem, give this a try and let me know if it solves it for you.

This will backup the current folder at /system/cameradata and copy it to your internal sd (its not big). This way if you need to you can just copy it back.

It will then copy the cameradata folder from the stock T999L build in its place.

Give it a shot if your camera isnt working and please report back so I know if it helps.

Thanks!

Hey Doc.

Could it be possible for you to create a zip file that we can flash on the T999L that has the modules included with the MB7 kernel minus the actual kernel?. Im getting kick ass battery life from the Deviant kernel. But in order for my cam ti work I have to flash the MB7 kernel + modules... if this is not possible then no biggie.. just thought id ask. TIA.
[T-Mobile, Samsung Galaxy SIII] The Sickness:
Have you tried Wicked V10?

Sent from a very Wicked T999
[T-Mobile, Samsung Galaxy SIII] jjluv86:
Is the camera zip only for cyanogen mod or can I use this for other roms as well like hyper drive rom

?
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Not a problem. Ill try to do that in just a bit.

But is the kernel you want an MD5 kernel? If so, those will be the modules you want. Ill make zips for both.

Are you using a custom rom?
[T-Mobile, Samsung Galaxy SIII] jjluv86:
And it's no biggie I don't mind waiting. I'm just very thankful your helping us and so patient!!
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
If you're having trouble with the camera on any rom, I'd encourage you to try it. Not promising it will work, as I've seen only a couple of reports on it before. One said it did, another said it did not.

Just let us know either way please.
[T-Mobile, Samsung Galaxy SIII] tj gamino:
Awesome!! Im running wicked V10. The aroma installer allows us to choose between 3 different kernels.. stock, deviant and xone dx. So far im liking deviant. Just have to flash MB7 with mods for camera to work. Thanks for all your help Doc. You have made the transition for me sooo much easier.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
But the camera isn't working on Wicked? I don't think the modules will help with that. Besides, you will already have the correct ones. Unless I'm mistaken, the kernel and modules have to match. If you use the MB7 modules, you're probably not going to have BT or WiFi working.

What is the camera doing? Has it been modded in any way? As far as I'm aware, the stock T999 camera should work on the T999L.
[T-Mobile, Samsung Galaxy SIII] tj gamino:
When I open camera on deviant kernel I get a error message and it closes. Once I flash any version of MB7 or MB5 I opens and is useable. I dont use Bluetooth or wifi at the moment so haven't even tried them out. Also, since im on V10. I get the option to install stock camera and/or note2 camera. Ive tried one at a time and both on the Deviant kernel with no luck. Flash MB7 and both work.
[T-Mobile, Samsung Galaxy SIII] jjluv86:
So far tried the camera zip on cm10 it worked. The hyperdrive rom it didnt work, kept getting a warning it failed. Im using stockorama rom and no problems with camera
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
That's kind of strange. Not sure exactly what could cause that. Maybe the modules will help...
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Do does the hyperdrive cam not work as is? Its an AT&T stock tom, do that's probably why. If you try it again, try either the MB7 or MD5 kernels with modules. Otherwise maybe the camera app and/or other files need to be swapped.

Glad to hear it worked on CM though! Thanks!
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Here are the modules you requested. Let me know if they work!

[T-Mobile, Samsung Galaxy SIII] athlonxp2300:
most any t999 rom will work. as long as it is rom only and not an odin version with full firmware. for the most part if the rom is flashed with twrp it should be good. most d2.... roms are compatible. d2tmo d2att d2ltetmo or in other words t999 i747 and t999l

I installed twrp for t999 and then s3rx 3. I used mostly stock options and mj2 kernel. only mod was to change my build prop to say SGH-T999L and d2ltetmo in several spots. that was mostly cosmetic. I like the model to show correctly.
