if you have a custom recovery like twrp and you install a rom like s3rx it won't have the modem in it. the same is true for most roms installed through the recovery. the rom may require you to be on a certain version modem for your phone. like a modem that came when the phone updated to stock andriod 4.3. but the rom won't have it in there. you said the phone was updated to the latest firmware then you rooted and got a recovery. (I'm not familiar with get high on android method) you should be able to make a nandriod backup in recovery. then factory reset then flash custom rom. (download custom rom to external sd first and check the md5 to make sure it downloaded right)

I understand about the flashing of the roms and recovery i dont understand about the modem flash would this be docs modem zip and do i flash it with the rom even if i have the latest update.again iam still a little green about this thanks for your help??
[T-Mobile, Samsung Galaxy SIII] athlonxp2300:
if you have a the newest firmware no need to flash any more modems. depending on the rom you may need a different than stock kernel. with s3rx my t999l was on latest firmware. after odin twrp and flashing root I wiped everything and flashed s3rx and chose att mj2 leaked kernel. it has worked well on numerous t999, t999l and i747 s3s.
[T-Mobile, Samsung Galaxy SIII] kennethdavis732:
I'm still kind of new to all this and I had the same questions and kept reading and still had problems, but some time and effort it was fixable and I found with the modems just download them all so you have them if 1 doesn't work and I haven't had a problem since just check md5 and flash, I also think your backup doesn't have the modem in it

Sorry got a little off track try flashing ROM then if you have a WiFi or data problem try a different modem and so on
[T-Mobile, Samsung Galaxy SIII] LARROW:
First of all thanks for the info anthlonxp2300. I flashed the s3 rx on my t999l. The rom worked well but the only problem was i had to change the apn settings. I could not sign on to google account and it gave me a message saying "Couldn't sign in there was a problem communicating with google servers". And it was laso giving me model number Samsung- SGH-1747. Other than that no problems, but i really need Google account for contacts and all my info. Any help will be appreciated.
[T-Mobile, Samsung Galaxy SIII] athlonxp2300:
sounds like you flashed s3rx from i747 or att forum. you should not have problems you should download the version 3 from t999 forum and install it. your phone should say it is a t999 unless you edit the build prop. the apn settings should be right after flashing but if not just add the tmobile lte apn. feel free to pm me so I can respond faster and not derail this forum.

Where and can you send me to the place you download from.i thought l download the right one before xda site.thanks for any help.?

---------- Post added at 01:49 AM ---------- Previous post was at 01:36 AM ----------

This is the rom i flashed S3rx_UCUFNE4_ATOMA_11-9-14
[T-Mobile, Samsung Galaxy SIII] athlonxp2300:
that is what I thought. That is based on the att version of s3. although it is kitkat it isn't officialy tmobile based. it can work but it would needs some tweeks and is why your phone showed as an i747 and apns were wrong. you have to make sure to factory reset first and then choose t999 option when flashing and probably need one of the non stock kernels.

once it is running good if you want the phone to show t999l as the model you will need a few build prop edits. not to hard to do.

s3rx 3 is android 4.3 and you can get it based on tmobile. check your pms or look back a page. I posted it there.

[T-Mobile, Samsung Galaxy SIII] IceHism:
Okay I've recently just flashed the root66 firmware that gave me supersu and all that.

My question is... Where do i go from here?

How would i proceed to

1) Install TWRP?, which version as well? Is 2.8 d2tmo fine? Can i have some instructions whether i use TWRP manager(goomanager doesn't seem to exist anymore) or do i have to go into download and flash through odin 3.09?

2) Installing a custom rom? I want to install Paranoid Android 4.6 beta 5 for D2lte but i'm not sure how to go about it. I have already downloaded the rom itself but not sure how to proceed from here. Also, how would i get the working and latest version of Gapps? (Also, can you tell me how to install Cyanogenmod 11 for d2lte as well?)

3) What are some cool apps to get?

4) Which root apps/roms/softwares will brick my phone? I'm never sure which thing will work and which won't.

5) how do i install xposed?

6) How do i remove all the bloatware? and how would i got about flashing through my phone without using the computer? is mobile odin compatible with my phone?

My phone is the SGH-T999L and i have no idea if i have a locked bootloader and how i would go about and bypass the limitations of this locked bootloader
[T-Mobile, Samsung Galaxy SIII] Perseus:
1. Go Via Odin. Safest. 2.8 is good.

2. Custom Roms are zips that are flashed via TWRP. The thread where you got Rom would give you Gapps. This applies to CM or PA Roms.

3. What's Cool for me is not so cool to you and vice versa. Can't help there.

4. Apps don't brick. The way you use them could. SetCPU for ex. will give an expensive paperweight if not used with caution. Note Boot Loop is NOT Brick.

5. This is really OT for this thread. But Xposed - General info, versions & changelog

6. [ATT/VZW/TMO/SPR + more] [De-Bloater / Utility / AROMA ] Ashaman v3.02 04.04.2013

Mobile Odin is compatible. Typically you'd flash most of the things in TWRP.

[T-Mobile, Samsung Galaxy SIII] imhungry:
With Mobilicity shutting down here, if I reset my S3 mobilicity phone back to stock following the instructions here and then unlock it to switch to Wind, can I flash other roms after that?

The instructions for reverting back to stock mention that I'd have to permanently unroot my phone, which would mean I'd have to go through unrooting it after unlocking it right?
[T-Mobile, Samsung Galaxy SIII] serio22:
1) yes

2) You can flash a prerooted root66 firmware if available for your device. Other than that, yes you would.
[T-Mobile, Samsung Galaxy SIII] imhungry:
Thanks for the reply serio.

I'm in the process of following the TWRP method, but I have some other questions:

If I flash back to stock, does that remove the TWRP recovery software?

I took a look at the root66 FWs at http://xdaforums.com/showthread.php?t=1949687 and I noticed that my phone is on T999VVLUEML2, does it matter which version I take from the thread for flashing?
[T-Mobile, Samsung Galaxy SIII] serio22:
1) yes, but you can easily flash it back

2) if you are on android 4.3 firmware or higher that you took an official OTA or update to, then yes it matters and you must flash ML2 or newer. If it's older like 4.1.x then you can flash any.

Recovery without volume buttons

Hello all,

Firstly, the volume buttons on my T999L stopped working. The buttons are good, the cable is good, the connector from ribbon to board is good. All this was checked with test equipment to confirm that the button signal was reaching the connector. All good there. So, I done a factory reset to see if it would clear up, but now it will not boot past the "T-Mobile 4G LTE" screen, it loops there forever.

The button issue must be hardware related, but at a chip level.

I was able to get in to download mode with a "dongle" so I tried reflashing stock through ODIN, it went without a hitch, however it still gets stuck at the "T-Mobile 4G LTE" screen.

I have read where others have had a loop at this screen and a data wipe/factory reset through recovery fixes the issue.

My question is, without working volume buttons, is there a way to access recovery so I can format data? Or is there a way to format data through Odin or another method?

I am not new to android "tinkering", but this is the first time I have ever had an issue where a button failure prevented accessing recovery.

Any help is much appreciated.

Thanks!!

Stock 4.3, future development for T999L

Is anybody working on 4.3 stock for T999L or is the project dead? I like CM11, don't like not having 1080 video recording and as of recent builds stock camera acts up. Mostly locks up or video recording problems. Because of the camera app whenever i use 3rd party camera app and dash cam app for video recording, phone reboots after a few minutes of recording. I reflashed gapps several times, reflashed gapps afer flashing nightly builds. Doesn't seem to help. Can't install google camera app, app already exists. It's getting extremely tiresome dealing with issues. I'm ready to trade some lag for stability. Seems like there won't be a 1080 video rec fix for s3 in the future.

The first APN you posted worked and I am one happy person right now! There wasn't a section for "extraid="6D", but at this point, who cares because it works.

I want to clarify what I said in my first post where I mentioned about the spaces in the link. I should have specified that the spaces weren't in the link on the phone, but rather that I had to add them in my post on the forum because I'm not allowed to have outside URLs in my posts yet because I'm a new user. Again, I apologize for that mix-up.

Thank you SO very much for your reply. I am so relieved that it's working now, it was literally driving me insane. I wish that the folks at Metro could have been this helpful. Thank you! Thank you! Thank you!

For KitKat Yes. Don't do so for Lollipop Roms. They are separated again. On LP you'd want to use D2ATT orD2TMO (If one is available)

Hi perseus and serio. I previously had some issues with one, cant recall which but after install, a prompt saying "Your device appears to have lost root" or something along those lines.

Is there a quick way to back up everything, including apps and texts?
[T-Mobile, Samsung Galaxy SIII] EmpiricalDepth:
Titanium Backup is like $6 and is awesome, but needs root. My Backup Pro i think is the same price, doesn't need root, but will not save app data, will just re-install them. If you just wanna do contacts, texts, call logs, and media like pictures and music, use samsung Kies on the PC and backup via USB cable. There are probably other ways but that is what I would do. I hope This got to you in time, and If not, you worked it out. Good luck :)

please thank my posts if it helped you.
[T-Mobile, Samsung Galaxy SIII] 2fiddy:

Will kies back up apps, text and data?
[T-Mobile, Samsung Galaxy SIII] EmpiricalDepth:
unfortunately I do not myself know of a free way to back up apps, as far as data is concerned, kies will back up media like photos and music, don't know specifically what else (if you know where it is, just copy it to the computer if you want like the phone is an external drive) but it will not back up apps or individual app data or settings. I'm pretty sure it will save most of your basic phone settings though. It will back up contacts, texts, and call logs as well.
[T-Mobile, Samsung Galaxy SIII] 2fiddy:
Don't mind paying at this point

I have maybe 15 gmail accounts and a lot of apps to restore, and very little time
[T-Mobile, Samsung Galaxy SIII] EmpiricalDepth:
if you plan to root after unlocking, get titanium, highly recommended backup with root by most in this community
[T-Mobile, Samsung Galaxy SIII] 2fiddy:
F*cked up

In my haste to get this sim card issue over with, i hit unroot in the superuser app, now root checker says phone is not rooted.

Can i fix this somehow, then install titanium back up?

Or do i have to do the whole rooting again?
[T-Mobile, Samsung Galaxy SIII] EmpiricalDepth:
I do not know for sure myself, I am fairly inexperienced. Incase you don't get a better reply, I will tell you what I would do. If titanium backup will not back up anything without root, use kies to back up everything you can just in case. Even if when you rooted last, it did not need a full wipe, I'm sure you'd rather only have to reinstall everything than lose all of it if something goes wrong. If you can use that unlock code now do it. Then re-root.
[T-Mobile, Samsung Galaxy SIII] Perseus:
Superuser Can Re-Root as well depending on your Case. Of course, you can reboot to your Custom Recovery, which can restore Root too.

I bought this T999L to travel and am trying to get it set up on latest. (my day phone is a sprint GS5.) I am on NC1 stock rooted with Philz recovery (TWRP would not read my sdcard). i have been doing some reading and would like to update to latest version with a working tether. Could someone point me to the correct link to update the rom. Is there a working tether mod, or is it in a rom? thanks for your help
[T-Mobile, Samsung Galaxy SIII] serio22:
What is your current build number? For tether you can use mods or maybe even xposed, but those methods need root access
[T-Mobile, Samsung Galaxy SIII] qwerty3656:
When you say "latest", do you mean stock rom? The latest stock rom for the T999L is NF4, but there is not a route 66 version of that ROM. There are also no custom Roms based off the NF4. I don't know why? I was in your position and ended up un-rooting my phone with the latest NF4 ROM then - re-rooting my phone (I ran into the same problem with TWRP and so ended up using CWM). I have since flashed S3Rx (but maintaining the NF4 Modem and Bootloader). S3Rx seems like a really nice ROM (and the installer provides a lot of options). I don't really know if there is any benefit to installing NF4 over just going directly to S3Rx.

Edit: One more thing the S3Rx is a Touch Wiz Rom which I needed to maintain wifi-calling. If you don't care about wifi-calling there are a bunch of "later" roms out there you may want to explore.
[T-Mobile, Samsung Galaxy SIII] cwb1231:
Do i need to do a clean install of the stock nf4 before the S3Rx or can i go right to current NF4 version of S3Rx

I misread. i see the last version of it is on NC1 so can i just flash the S3Rx NC1 version over what i have.. Does NF4 bring any real pluses to the phone?
[T-Mobile, Samsung Galaxy SIII] Perseus:
Typically, its the belief that using latest baseband is "Supposed" to bring Defect fixes, improve communication and so on. Otherwise, you can always follow the universal law. "If it aien't broken why fix it ?";)
[T-Mobile, Samsung Galaxy SIII] qwerty3656:
There is no NF4 version of S3Rx (or any other custom ROM for that matter). I don't know if NF4 brings any pluses (like I said, I have the NF4 Modem and Bootloader - I don't know if they are any different than the NC1 modem/bootloader). If you do install S3Rx read the last few pages of posts about editing the build.prod file.

How can I get rid of Bloatware? There's so much crap on my new T999-L that i don't want or need. I rooted it using this one-click root method from wonderhowto so I'm not running any custom ROM, just stock. I went through Root Explorer to try to find where all the bloatware is hiding and didn't notice any of the apk's.

This is the second time I am rooting a device myself. The first time I tried was over a year ago and I soft-bricked my Galaxy S Relay and it took me a long time to get it back to original stock where I kept it until it's demise a month ago due to a bootloop.
[T-Mobile, Samsung Galaxy SIII] athlonxp2300:
First use odin to install twrp for t999 (it works for t999l) then make a nandroid backup. then you can use programs like esfile explorer to remove apps and if you screw the phone up you can restore the backup. you can also install s3rx 3 and edit build prop for a awesome tw rom.

you can try twrp manager from playstore to install twrp but odin is better imo.
[T-Mobile, Samsung Galaxy SIII] RockinRita:
only have access to a Chromebook...cant download any exe files...anything else I can do?
[T-Mobile, Samsung Galaxy SIII] qwerty3656:
If your already rooted, you should be able to download titanium backup from the app store and remove bloatware.
[T-Mobile, Samsung Galaxy SIII] athlonxp2300:
You could try twrp manager from the Play Store if you have root. But I would make sure you know somebody who has a computer that you could use if things did go wrong. it's always best to have custom recovery that you can do nandroids. You could probably also use mobile Odin to flash the recovery.

edit: to fix twrp manager

Hello! I probably should have been posting here all along.

I received a T999L as a replacement from TMO > auto updated to 4.3 > wanted to remove bloatware > installed Root66 with Odin. Now I am having tons of notifications issues. Basically not receiving them for different apps. System apps seem to do a bit better with notifications.

OK. There is a newer firmware then what I have on my device. I am scared to death to brick this thing. I am a Mom and need my phone. End sob story.

Can I flash the latest firmware that I downloaded from SamMobile with Odin and is there ANYTHING else I need to do post or pre flash? I assume once I flash the latest firmware I will then be in default settings but all my apps, contacts, etc. should still be in place, correct? Next, I want to re-root but from what I am being told I cannot re-root with Odin (Root 66) again. So what is the recommendation? What have I missed in this post? Ha! I need to do this badly because I am missing really important notifications. Thank you!!!!!
[T-Mobile, Samsung Galaxy SIII] serio22:
Yeah you should still have everything, even your settings if you update by flashing the firmware. You should still backup anything of importance. As for root66 check the thread. If the firmware is there then that's all you need, it is the firmware but pre-rooted. If it's not there then you can use towelroot I believe, or cf-auto-root. Make sure to read about each one before you make a decision. Also run stock without anything removed for a few days and see if your notifications improve
