Need help with root - T-Mobile, Samsung Galaxy SIII

I looking for a tutorial on how to root a Samsung Galaxy S3 and on how to install CM 12.1.

Root is not required to install a custom ROM. All you need to install CM12.1 is TWRP, the CM12.1 ROM, and gapps.

I need help too hete

To flash a custom ROM, use Odin to flash TWRP from here: https://dl.twrp.me/d2tmo/
Once TWRP has been installed, you can boot into TWRP to flash a custom ROM and Gapps.
If you just want root, flash supersi from TWRP: http://forum.xda-developers.com/showthread.php?t=1538053

[Q] I'm trying to get cm 10 on my telus s3, but I have a couple questions.

Ok. So I have twrp recovery installed via goomanager. Is this compatible with cm 10 stable? Also I need the d2att version right? I'm really scared about bricking so could someone just fill me in with some details.
I have decided to unroot because I just don't get it. Ill reroot with the method I know how to use.
Yes on both counts.
Goomanager will install a d2can recovery image on your device; you'll need to install the d2att image manually to get it to flash d2att ROMs.
Also remember to clear data/cache before trying to start the new ROM, or before you flash it.

One more thing, I have my phone rooted with a no tripping counter way that I did through odin, I'm sure you have heard of it. Can I just reflash the rooted rom that i originally rooted this with and have that custom recovery uninstalled? Or should I flash an unrooted version from the samsung website? Just so I know how to get rid of this recovery.

Yes.

[Q] Can't Root? What are my options?

I have an i747M, from Fido (rogers) running the stock 4.3 firmware. yesterday i tried to root it using odin to install CWM, and then CWM to install supersu.
after successfully installing supersu, i restarted the phone, and got knox blocking the app. i updated it from Play, but then i couldn't open it, and it said it can't install the binary. when my phone asked to update the security certificates, i (stupidly) agreed.
i downloaded the .zip for supersu 1.89, and tried installing that, with the same result, but this time i also can't uninstall supersu.
i've bumped my binary counter, but i'm back to basically stock now.
my goal is to install aokp. is there a way to do it without gaining root first?
if i install CWM through odin, can i flash the aokp rom from CWM?
will the phone reset the recovery?
is this risky?
You could try installing a pre-rooted Rogers rom from here: http://forum.xda-developers.com/showthread.php?t=1739426
I was not able to find a pre-rooted 4.3 for Fido and, since you intend to install a custom rom and recovery, the pre-rooted Rogers ROM might be a good place to start.
It's there a reason to install a rooted rom before aokp? As far as I can tell, I can install aokp without rooting at all.
or am I missing something?
Sent from my SGH-I747M using xda app-developers app
Yes, you can just install a custom ROM without rooting first.
I mentioned the prerooted ROM because you post said you wanted to install su.
Ok, please confirm i have this procedure correct:
1. i use Odin to install CWM
2. boot straight into CWM
3. from inside CWM, i flash the AOKP zip file, and then the gapps zip file
my understanding is that this will keep cwm as my recovery and install aokp with gapps.
am i missing anything?

Just make sure you flash a tar version of CWM that is meant for your phone.
I can't really speak about 4.3 because I'm on 4.1.2 but the method you described is the same method I used.

If you want to kill Konx to enable root you can flash this knox removal script: http://forum.xda-developers.com/showthread.php?t=2507931
If you are just going to flash AOKP via CWM, this may not be necessary, but this is the answer to your Knox problem.

If you want to flash the full firmware, then download it from sammobile.com and flash it using Odin.
Then you can install custom recovery with Odin.
Be aware that if you flash the full firmware package, it has a new bootloader that doesn't play nice with custom recoveries. If you use any software method to boot into your custom recovery, you will get stuck in recovery and must flash stock recovery to be able to boot the OS. You can use a custom recovery only if you POWER OFF; then use the 3-button method to boot into your custom recovery.

Not rootable!?!?!

So i've had my gs4mini a while now and it refuses to root.
it is i9192 (dual sim) out of box running 4.4.2. cf-root fails and i'm running out of options. I really want cm 12.1 on my device.
how can i achieve root?
is it true that i need root to install a custom recovery? like the one posted here http://forum.xda-developers.com/android/general/root-samsung-galaxy-s4-mini-dual-sim-gt-t2819284
any advice will be helpful.

Your goal is to use CM12.1, you can directly flash custom recovery via Odin then proceed with CM installation steps.
You don't need root to install custom recovery.
& CF-AUTO-ROOT is meant to root the devise without replacing stock recovery and trip Knox warranty status.

[Q] Custom rom already rooted

I'm running a custom rom but cannot get magisk to work. I've done everything discussed in that rom's thread to get root but no success.
Does anyone know of a custom rom for the 2 XL that installs with magisk or SuperSU included?
Just to get more info, after flashing the rom and twrp zip, you boot into the os at least once before going back and flashing Magisk right?
lineage rom could be rooted natively. you doesn't need to install magisk to obtain root
