[T-Mobile, Samsung Galaxy SIII] Jack Test:
The phone never flash the unofficial firmware, so it might even on USB debug off mode. And I can't get to recover mode either. I think it never get to version 4.3. Somehow it stuck in S3 Logo, my kid used the phone, and he is not sure which version it has upgraded to either.

Only thing I get to is the Download mode. Guess the phone is bricked, unless if there is a way it can boot to micro SD?
[T-Mobile, Samsung Galaxy SIII] audit13:
The phone is not bricked if the phone will enter into and stay in download mode.

Boot the phone into download mode. Do you see anything on the screen about knox or warranty bit?

First time rooting my old T999L. Thanks to [MENTION=4845222]cLogic[/MENTION] for this guide! It might be worth adding a line to the OP about unchecking Auto Reboot and pulling the battery. That's what worked for me to get TWRP installed.

A little help here,

My mobile is sgh-t999 it shows warranty bit 1 how to reduce it to 0

I have already flashed it with latest firmware but doesn't work.
[T-Mobile, Samsung Galaxy SIII] audit13:
You cannot change the warranty bit from 1 to zero once it has been changed to 1.

I am unable to flash any custom recovery because as I flash my phone is not going into boot recovery mode
[T-Mobile, Samsung Galaxy SIII] cLogic:
you flash a recovery via Odin in download mode .. power + home + volume DOWN

the warranty bit does nothing .. it only means that samsung can refuse to fix your device IF you go thru them
[T-Mobile, Samsung Galaxy SIII] Jello1:
Hi All.

Lowly US college student. Inherited an S3 from older brother.

Need to install apps for McDs etc for coupons.

Must. feed. self.

Phone model is Samsung Galaxy S3, T999L (t-mobile)

Baseband: T999LUVUBOH1

KERNEL: 3.0.31-2016417

Android ver: 4.3

Goal: Install CM12.1 Official and hope that its good enough for Mr. Play Store.

Progress so far:

Have managed to Flash TWRP 3.1.0-0 for d2tmo

Used Odin307. Had to remove battery on the 5th flash attempt as rebooting would restore stock recovery.

Managed to remove Knox (i think) using the script here.

Sifted through alot of posts/ threads/ youtube vids.

Kingroot, towelroot failed. CF-Auto-root, and numerous SuperSU versions including 2.79 were installed through TWRP Recovery. but upon rebooting, Android would update yet, no icon for SuperSU would be seen.

Rootchecker says the phone isnt rooted.

Please help me root, so that I may install cm 12.1.

Sorry for any breach of protocol or offence. Didn't want to start a new post. Seemed too greedy.
[T-Mobile, Samsung Galaxy SIII] cLogic:
there is no need to root first if you are changing the rom :D

if you have installed twrp already, download required files to external sdcard then boot into twrp recovery and

full wipe .. system, internal data, dalvik, cache

flash the rom (cm)

flash appropriate gapps

flash superSu

reboot

it will take awhile for first start.. could take as long as fifteen minutes before it finally starts to compile the apps (optimize)

you should be able to flash cm13 (marshmallow) on the s3, altho you could flash cm12 (lollipop) if necessary

good luck.. let us know how it went :good:
[T-Mobile, Samsung Galaxy SIII] Jello1:
Thanks a ton for the reply.

Im updating simply to give thanks for the reply.

I happen to be the "measure 700 times to cut once" kinda guy.

Ive downloaded quite a few files since that time.

Managed to root finally! Used the SkipSoft Toolkit. Asked to fix the SuperSU app not appearing. RootChecker verified and Titanium Backup easily removed an app.

Wanna make sure I get the right CM version and the correct GApps (there are so many!)

Will update with final result, wish me luck!
[T-Mobile, Samsung Galaxy SIII] cLogic:
you know that cm, cyanogenmod, is finished, right?

they had to stop

they are now LineageOs .. https://www.lineageos.org .. and they are on android N, nougat, 14.1

if you use d2tmo device, you'll see the rom here .. https://download.lineageos.org/d2tmo

if you want older versions of cm, you'll have to look for archives on servers

cheers
[T-Mobile, Samsung Galaxy SIII] Jello1:
Yeah i figured that out. Read the wiki page too.

I got the latest LineageOS nightly for dtmo off their site as well, but I don't know which GAPPS to use with it.

I'm not worried with download or install size.

However, my greed is increasing.

I went from wanting a new OS to keep up with today's App requirements to wondering which extra options i would lose if i got stock/full/mini/micro GAPPS.

still wondering...
[T-Mobile, Samsung Galaxy SIII] Jello1:
Alrighty. So I did it.

LineageOS 14.1 was installed. with GAPPS (full).

Everything is running smoothly. Battery drain is somewhat worrisome.

Will be googling and youtubing possible solutions.

Solves my problems nicely so far. Messages being sent by SMS are working. Wifi connecting and location settings are good as well.

Installed the clock/weather widget (first time!)

Able to install most.. wait.. ALL the apps off Play store just as I wanted.

TY very much for all help.
[T-Mobile, Samsung Galaxy SIII] cLogic:
if you still have these issues, then sure ... put the 2.6 TWRP and repeat the knox removal and all procedures .. can't hurt
[T-Mobile, Samsung Galaxy SIII] cLogic:
are you sure it is actually stuck?

I did the same thing .. flashed stock 4.3 from samsung-updates.com via Odin .. it is huge, 750MB zip, 1.3GB tar .. and took awhile to boot the first time .. logo pulsed for almost 5 mins

technically you can flash any 4.3+ firmware any time you want .. stock, root66, custom rom, etc
[T-Mobile, Samsung Galaxy SIII] Alfred1516:
Can i use CWM instead of TWRP
[T-Mobile, Samsung Galaxy SIII] cLogic:
altho I haven't used cwm recovery since My early days of flashing, and not sure why you would want to use it, recovery is recovery ... I don't see why it wouldn't work, but don't blame Me if you have issues :P

just make sure you get the latest version specific to your device
[T-Mobile, Samsung Galaxy SIII] Alfred1516:
K i will use TWRP then, thanks bu i wont lose my data by doing this?
[T-Mobile, Samsung Galaxy SIII] cLogic:
if you have doubts, when in recovery, do a (nandroid) backup BEFORE flashing anything
[T-Mobile, Samsung Galaxy SIII] Alfred1516:
K but thanks dude
[T-Mobile, Samsung Galaxy SIII] masondoctorjt:
I was using cmw, and something wasn't flashing right with it. I installed twrp and everything went well, So I agree with you saying to use twrp.
[T-Mobile, Samsung Galaxy SIII] Alfred1516:
Im root now and i have CWM 6.X and how can i go to twrp by flashing it or what?
[T-Mobile, Samsung Galaxy SIII] orbin:
Thank you!

I have a few questions, just to be on the safe side:

1. Is there a real risk? Because you warn that "Following any of these instructions ... could possibly cause irreparable harm to your device (i.e. bricked) - is it just as every tutorial warns, or there is any special risk?

2. Should I have any problems to flash CWM and then CyanogenMod after finishing the process?
[T-Mobile, Samsung Galaxy SIII] nagahanala:
Will this trip the knox warranty bit, from what i gather if you install the custom recovery first that will trip the bit or am i wrong?
[T-Mobile, Samsung Galaxy SIII] Dyn4myT:
Hi,

I have a question about this root method and the new update for the videotron device.

If you check sammobile, you will see the update from january 3rd, I don't have any info about this update, maybe the knox issue.

Do you know what i'm talking about ?

Does this root method will work with the update ? I won't apply if this is for knox.

Thank you

(sorry for my poor english)

Worked for me on SGH-T999. I gained root access, and after that even succeeded flashing CyanogenMod 11 (4.4.2).
[T-Mobile, Samsung Galaxy SIII] toeshot:
At this point I would have to say it will trip that bit. There has not been anyhting said about this warranty bit being able to be reset except that it is impossible. When that waranty bit is tripped you will not be able to use odin to down grade a rom even an official ROM. You can always flash a Custom ROM that is previous to 4.3 with the Knox Warranty bit tripped.

See this thread for some testing I have done.

[T-Mobile, Samsung Galaxy SIII] nagahanala:
So just want to verifiy any custom rom will work and stock 4.3 over odin with work correct?
[T-Mobile, Samsung Galaxy SIII] cLogic:
yes .. just like cwm, twrp is simply a recovery image

on samching devices ..

- if you use a tar file, flash via odin

- if you use a img file, flash via goo manager, rom manager, flashify, etc
[T-Mobile, Samsung Galaxy SIII] cLogic:
1. yes, there is always risk when you modify/customize firmware

special/different risk than any other flash? no .. this guide is simply flashing a recovery image and then using that custom recovery to run two scripts: one to remove knox files and one to install superSu

can you brick using this guide? yes, you could flash a recovery for the wrong device and/or to the wrong partition .. that would be user error, by choosing wrong recovery (example recovery for i9300)

2. no .. I don't see why you would have any probs, altho if that was your intent then you don't need this guide

this guide is for removing knox and rooting the stock samching rom

if you want a custom rom, simply install a custom recovery (twrp or cwm) and then flash the custom rom (and gapps) from there

most custom roms are already rooted, but if not, simply boot back into recovery after the rom has booted successfully and install the superSu zip
[T-Mobile, Samsung Galaxy SIII] cLogic:
I'm not entirely sure what you mean ... do you want to keep knox or remove it?

yes, there are two android 4.3 updates for videotron, basebands MK5 and ML2 ..

I have MK5 which has knox .. this guide WILL Remove knox and add Root for MK5 :)

videotron os updates webpage http://soutien.videotron.com/residentiel/mobile/appareils/mise-a-jour-systemes-exploitation

was last updated dec 16 and does Not mention the ML2 update, so I am not sure if it is official and I will NOT install it, yet
[T-Mobile, Samsung Galaxy SIII] cLogic:
you could probably push the recovery img via adb using the instructions on twrp site, I think

good luck
[T-Mobile, Samsung Galaxy SIII] cLogic:
that's what the Thanks button is for, lol

:good:
[T-Mobile, Samsung Galaxy SIII] TwistTheNeil:
But I don't have a custom recovery installed yet. Can i install twrp/cwm without odin?
[T-Mobile, Samsung Galaxy SIII] cLogic:

tell Me:

what is your phone device model ?

are you familiar with adb ?

how familiar are you with linux ?
[T-Mobile, Samsung Galaxy SIII] sgkean:
Thanks cLogic. My S3 is working fine now, no more Knox, can open supersu again and get root access.
[T-Mobile, Samsung Galaxy SIII] TwistTheNeil:
Sorry, I'm really new to android..

1. SGH-T999 (T-mobile)

2. Very little. I just know about push/pull

3. Pretty familiar with linux
[T-Mobile, Samsung Galaxy SIII] toeshot:
yes
[T-Mobile, Samsung Galaxy SIII] cLogic:
you'll notice on the TWRP device page that they mention how to write the recovery.img file using adb

http://teamw.in/project/twrp2/106

this page is a different method, also using adb, which also shows Linux specific stuff, both for installing adb linux and recovery

http://www.droidviews.com/a-comprehensive-guide-to-adb-android-debug-bridge-and-commands/

I take no responsibility for any problems you encounter

fyi .. you may want to search, here on xda and elsewhere, before asking for a how-to .. usually the answer is already out there, especially for an older device :cowboy:
[T-Mobile, Samsung Galaxy SIII] TwistTheNeil:
All those methods require root though..

I found nothing which used linux. I know about heimdall but d2tmo is the only one which isn't supported. But i'll search again!

Just wanna say THANKS!!! I've gone from "near-complete noob on rooting" to "successfully rooted and tinkering with new options" in just the last few hours, and after problem after problem and immense aggravation, Knox was the last thing standing in my way.

Stuck on step 3

Hi. Ex Blackberry guy here, so be gentle with me...

I have gotten to step 3,

3. Reboot into Recovery mode ... VolumeUP + Power + Home

Flash (install) the Knox Remover zip

Flash (install) the SuperSu zip ... it is version 1.65, current is 1.80, so it will prompt us to update later

Reboot System

but don't know how to flash (install). At the end of step 2 I disconnected from pc, so I assume this is all done directly on he device? I was in download mode, but couldn't do anything. I tried searching, and found that I could pull the battery and start over so I did, i went reebooted into download mode, but then went with volume down, and it started normally (no brick), but when I when I went to downloalds and clicked on knox remover it said unable to run. I THINK I need to reboot into download mode and use Odin to flash them, but thought I would check first.

Thanks!

when you boot into Recovery mode (volumeUP+Power+Home), are you seeing the TWRP menu ?

[HELP] My phone keeps rebooting

I have samsung galaxy s3 sgh i747 running stock. I used to have root access to my phone until last night when my phone started to reboot constantly. I finally have my phone work again by recovery to factory. But then I cannot root my phone! I used every method possible, but every time I was about to update superSU, my phone started to reboot constantly again. HELP. :crying:
[T-Mobile, Samsung Galaxy SIII] johnny quest:
I'm trying this out and whenever I go to flash a zip in the background image there's a android with an red x kind of image, but the choices I have are these:

reboot system now

apply update from ADB

apply update from external storage

wipe data/factory reset

wipe cache partition

apply update from cache

These are the choices and when I go to "apply update from external storage" I would see the zip files. So I flash the Knox zip but then it reboots on its own. How would I know if it worked? I still see the Knox app in my app drawer.
[T-Mobile, Samsung Galaxy SIII] twizzler66:
no TWRP

So, I have a Wind SGH-T999V running Android 4.3 with Baseband version MK5 - I have tried multiple times to install TWRP (openrecovery-twrp-2.6.3.0-d2can.tar) using Odin as per this guide - it seems to install fine but when I reboot into recovery I get the stock Android recovery screen.

I attempted the "disable auto reboot" suggestion, and pulled the battery and immediately rebooted into recovery mode, but still reboot to the stock Android recovery screen.

I installed GooManager and when searching for a TWRP version to install it selects the same version I listed above and it appears to install just fine, but the built in feature to reboot into recovery mode does nothing, and when I manually reboot into recovery I still get the stock Android recovery screen.....

Does anyone have any other suggestions on how to get TWRP recovery to load correctly or is there anything I can look for to verify that the recovery image installed correctly?

Any help would be appreciated...

EDIT: saw this on another guide for rooting - can anyone comment?

"You can't install custom recovery and custom ROMs on a phone with a locked bootloader. This rooting program does not unlock your bootloader and won't allow you to flash custom on a locked device. However, NOTHING allows flashing a custom recovery on a bootloader locked phone at the moment. See Safestrap for a way to install some custom ROMs."

When i try flashing twrp it says seriel/com port cant open, what can i do to fix this? I already have the phone back booted but wanna know what i can do to get pass this part so i can root
[T-Mobile, Samsung Galaxy SIII] johnny quest:
Trust me when I tell you this, I am in no way a Dev. With that said; this is what I did: I unrooted my GS3 and then installed the recent recovery thanks to Serio22. He's helped me completely. Ok, so now I was able to flash the recent recovery but I had problems rooting because after I installed the recovery my phone now was in the 4.3 with the OTA update. So I think this gave me problems because of the whole Knox thing, I think. So I couldn't flash anything because CWM wasn't working. With the help of Serio22 he got me to flash the most recent TWRP and then everything was working. I was able to flash Superuser and now my phone is rooted again.

So, I would say make sure you're on the latest TWRP, and on your phone then flash it. That could be it. I think its the 2.6, I heard that the 2.5 is bad. I hope this helps. Sorry if it didn't, but again Serio22 was patient with me and helped me a lot, you may want to touch basis with him.
[T-Mobile, Samsung Galaxy SIII] absinthesummer:
I had no issues when originally installing CWM on my S3, but when I tried to flash TWRP via goo manager, it just would NOT work. I tried multiple times, so I flashed it using a different app and it finally worked. It was either ROM installer or Recovery Tools-Flasher. Sometimes, GooManager won't cooperate. You could try that, maybe?

Also for those having difficulty getting into recovery- my phone may just be weird, but on mine I press Vol Up + Power to get in, not Vol Up + Home + Power. I don't know why, but the "official" way just boots my phone normally instead of taking me to recovery.

Lastly, for those having problems with Super SU and reboots, you could try to make sure SELinux is set to permissive, as mentioned in an earlier post in this thread. (Apparently SELinux not being set to permissive can cause stability issues with SuperSU) OR you can try flashing the newest version of SuperSu. If that doesn't help, you could try replacing SuperSu with SuperUser and see if that alleviates the issue. I prefer Super SU also, but if you're sure the problems are linked with it and your SELinux is set to permissive already, it would be worth it to try replacing it with SuperUser. Beyond that, I don't know, but I would start there and see if it resolves the problems you are experiencing.
[T-Mobile, Samsung Galaxy SIII] twizzler66:
Thanks to absinthesummer for the suggestions.

As it turns out, there were issues with my PC's USB connection - I was getting a popup as if my PC thought I was plugging in my scanner. Even though things appeared to flash correctly I just could not get custom recovery.

I ended up taking my phone to work and used my PC there and got everything installed no problem!

Thanks to everyone offering support in this thread! :)
[T-Mobile, Samsung Galaxy SIII] absinthesummer:
Good! I'm glad you figured it out and found a solution. Hope the others in the thread find solutions also :)

Thanks to The OP.

I've been searching for this. It amazingly works on My Samsung Mega GT-I9200. Its latest ROM (XSE) annoyed me a lot as it blocked any way to put superuser to work.

I flashed the script, then superuser, using CWM. Now I'm free to get into the system and remove any bloatware.

Thanks again

Bluetooth problem

Hi,

I put this ROM on my SGH-T999V somewhere in December and is working fine for most of the applications.

But.... My bluetooth connection keep failing on the phone side... is like there are no device paired at all. When in my car, the car bluetooth is asking for connection, but in my device list there is nothing, is empty. Same with my home phone... If I pair again the devices, everything works just fine... until it doesn't work anymore and the list becam empty again :(

help me please
[T-Mobile, Samsung Galaxy SIII] jaesun:
Samsung GS3 SGH-T999 TMobile. Was completely stock, unrooted, but had to be sent in to Samsung for repair (LCD/Digitizer broke). And apparently, when I got it back, they wiped my phone (despite telling me they wouldn't), upgraded me to 4.3 JB (I was on 4.2). So decided since I lost everything, I would root and install Cynogenmod and try out something new.

For some reason, didn't work the first time around. Everything seemed to go smooth, no errors. But when it rebooted after installation and removal, Android would boot up, optimize apps, but root was not granted. It seemed Knox as gone (no longer in the apps list, etc). But got error that it was shutdown on startup, and couldn't open the app.

Decided to install TWRP 2.7.0-d2tmo . Worked fine. Hoping it doesn't have the issues that 2.6 had.

Just wanted to say thanks!

Hi, i have a Samsung Galaxy s4 an I used the cwm method to root.

However, I was unable to get SuperSU working as I had knox installed. I found this thread and followed the instructions to install the two zip files, phone is now rooted - only down side is ever time the phone lock screen is activated either through timeout or by pressing the power button the phone will go into a restart loop.

Is there any fix to this? please help!
[T-Mobile, Samsung Galaxy SIII] Perseus:
For one you are on wrong Device forum. You should head over to the that Forum assuming you have T-Mo. Second If you flash anything on this forum, you run the risk of bricking.

Having said that, you need to flash the insecure kernel first that will turn off SELINUX enforcing. That in turn will allow you to get stable Root.
