Rooting and upgrading software questions - Samsung Galaxy S3 GT-I9300T - General Questions and Answers

I hope this is the correct section to post this. I have a sgs3 GT-I9300T that is/was carrier locked through Vodafone. I say is/was because I can currently use an Optus simcard without problems. This specific model does not support any upgrade past 4.3 jellybean (which is bs lol)
So here I am, a complete phone noob, wondering how to root this specific model and upgrade to at least the 4.4.4 KitKat port ive seen posted. Is there any guides or how tos on the subject? Is there a difference between both GT-I9300 and the T variation in terms of rooting/flashing custom roms etc?
I have a dream to become Pokémon master but my phone is not allowing me to become one. Please help me

can anyone help?

[Q] Galaxy S3 Rooting - T-Mobile UK

I've a Galaxy S3 locked to T-Mobile UK. Model number is GT-19300, currently running Android 4.0.4.
T-Mobile UK have removed the OTA update functionality and i'm impatient, and want to upgrade to JellyBean.
I'm fairly new to all of this, but have some experience of rooting and flashing from an old HTC Hero.
I don't want to change to a differently themed ROM and don't care for all the different features that rooting would bring to the phone. I would just like to flash the bog-standard Samsung UK S3 ROM so I don't have the T-Mobile OTA update lock on there.
Is this possible to do? To restore the phone to an unlocked state, capable of obtaining updates without all the bloatware T-Mobile will put on when they finally release their JellyBean update. If so, i'd appreciate it if somebody could point me in the right direction of a ROM.
Apologies if what i'm asking isn't clear, as I say, i'm fairly new to it all!
Many thanks.

[Q] Rooting Galaxy S4 with CF-auto-root (Canada)

I couldn't find a solution too specific to my phone, but was mostly just wondering, Does anyone know if the newest CF-auto-root is compatible with a Canadian SGH-I337M; Ver 4.4.2; Baseband VLUFNE1 on the MTS network? if so, where is a safe download source of the .tar?
And if not if there is anything that is compatible? Keep in mind im not looking to flash custom roms, i essentially want root to use rooted apps and all the devince freedom that comes with it. essentially a basic root. Also Ive previously rooted my S2 and an old motodroid so theres no need to review the rooting process ive got that down.
Thanks, any and all advice is appreciated!

[Q] Questions about root methods (towelroot) and not "tripping" Knox

Just read some posts in the towelroot forum, and I had some questions - but first, a little about me:
I'm coming from an HTC Evo 4g LTE (Sprint) and I just switched to Ting (uses all Sprint towers & devices, just an a-la-carte payment plan as opposed to monthly)
Anywho, all this Knox business (and acquiring root for the S5) is new to me (but I am no newbie when it comes to root, just my first time owning a Samsung device.) I havent even had this phone for 24 hours yet.
Just wanted to know what build/kernel/Android version you were on when you attempted towelroot?
I am on Android 4.4.2 - Build: KOT49H.G900PVPU1AND2
I did not install the System OR Software Update that is in my notification list after activation. (Pretty much same rules were for the HTC Evo 4G LTE, it would update the bootloader to a version that was considered "unmoddable" at the time) and for that phone it was also called "S-OFF" (S stood for Security) - Im guessing Knox is somewhat similar...?
Also, what is the preferred root method for the G900P? I only know of towelroot and CF-Auto-Root (sp?) - I know Chainfire makes apps specifically for Samsung devices, but read an old post on another site that CF's method will "trip" Knox... is that still accurate?
Just wanted to be 100% confident in what I'm doing, before I attempt anything. (Again, I have a lot of experience in HTC devices; not so much with Samsung) :/
Any help regarding my device and acquiring root without "tripping" Knox is greatly appreciated!
Thanks in advance! - zmag

To add to this I just purchased a S5 coming after an S1 and S3.
I am wondering if I have to worry about any updates on sprint locking me out. My S3 is on Verizon and luckily I rooted it before they came out with the update that locked it out. Can I go to the newest version that my phone wants to update me to without any fears of being locked out in the future?

Currently for the Sprint 900P (not the 860 Sport) NE5 is the latest build and I have not heard of anything being patched to not allow root.
However, it is best practice to always wait on taking any new Sprint updates until the devs have time to look into it and make sure root is still possible. There is no way for anyone to know what Sprint/Samsung/Google will patch in future updates. It usually only takes the dev community about a day or so to confirm whether existing root methods will still work.

As I suggested in a previous post of yours you'll want to look in the development forums for current devs who are still supporting the contract S3, it's merely a matter of doing a quick search inside the development forums
And being that it's on the 4.3 bootloader, it's locked down, the only possibility are bootloader locked roms but a dev would have to have this specific phone to be able to create a rom for it and there wouldn't be much as far as roms go

[Completed] AIO/Cricket Galaxy S4 I337z, need help to figure out if I can flash my phone

I recently bought a Samsung Multi Media dock that I finally got to work reliably. I'm not impressed with the experience so I want to flash my phone over to a custom rom so I can tweak settings (and recover from it if I screw it up). I used to have a custom rom on my last phone but since I had to replace it when Cricket nuked their CDMA network I'm stuck with a stock Samsung Galaxy S4, with touchwiz- I hate touchwiz.
My brother kind of held my hand when my phone was first flashed over to CyanogenMod, a more accurate description was that he sabotaged it giving me little reason not to flash a custom image, so I'm still a bit new at this. I've gone threw the forums with the intent of reading up on weather I can and how I should go about flashing my phone. Problem is that I can't find anything that directly relates to the version of the firmware I have and I don't know if its compatible with any of the methods on the table.
I'm rightfully terrified of bricking my phone. I at least want some encouragement of reading about people with a success rate with an identical device before I go off and potentially brick my phone, if I do brick my phone I want it to be completely my fault because I plan on reading every guide and forum thread twice just to make sure I don't miss a nuance of the process.
Anyway,
i have a Galaxy S4, SGH-I337Z
Build #: KOT49H.i337zTUUBOA1
Android Ver- 4.4.2
security software ver: mdf v1.0 Rel 2
any combination of that information just points me to similar threads with no 100% (or even 50%) identical information. I've got three threads open in tabs rite now that say things about MD3 or MK2 firmware and I have no idea if I have those or not.
Anyway I'm hoping someone can find the info I'm to blind to find myself.
Thanks in advance!
