[Q] Galaxy S3 Rooting - T-Mobile UK - General Questions and Answers

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.

Telus Samsung Galaxy S2X 4.0.4 Update?

Hi guys, I was wondering if there was any Telus 4.0.4 updates for the S2X and how would I install it. I am fairly new to this flashing and rooting stuff. I'm just afraid I may brick my phone and.. of course nobody would want that since that pretty much sucks.
I found some 4.0.4 ROMs or something for Koodo and T-Mobile S2Xs but I'm looking for one for my Telus phone and how would I install it. Just to be more brief, my phone is unlocked by the way.
Thanks for any replies.

[Q] Galaxy SII firmware help

Hi I have a Galaxy SII SCH-R760. It is a non US Cellular version as I got it from my small town local phone provider. I had been reading about the SII being able to use ICS and wanted to update. However I accidentally pulled a stupid move and flashed it to the US Cellular firmware. Is there any way to get it back to stock firmware or is there at least a generic firmware I can install? The phone is not rooted and I would like to keep it that way for now if possible.
Thanks a million
Jon

[Q] Can we root without flashing and will we be able to receive OTA updates?

Hi, i own galaxy note LTE N7105, and decided I want to root. one thing though that bugs me, is people complaining over inability to update to new official OTA updates, since I want to keep my Note up to date with the manufacturer, I would really liked it if I can update.
Also, I want to root without flashing custom firmware. Can it be possible? Thank you.
edit : I own non carrier phones, So it is not locked.

Note Pro 12.2 rooting, VZW or AT&T?

Hi, reading through the forums, it sounds like rooting a Note Pro 12.2 on Verizon is either very difficult, or impossible? I'm going to buy one of these for either VZW or AT&T to test for my team of 6 salespeople to use in the field and would need it to be rooted so we can use multi window on all apps. Would prefer VZW because I have most of my devices there now and use Message+ which is awesome for texting on all my devices. But if I have to go AT&T to root, I'll do that - I think this functionality is more important to us. I'd appreciate any input you have on this, and also if someone would be willing to walk me through the rooting process I'd be happy to compensate. Thanks, Scott

Rooting the Verizon model is very easy as long as it is on Android 4.4 (Android 5.1 was recently released for it and is not rootable)
The instructions here are what I used, they are very straightforward: http://forum.xda-developers.com/showthread.php?t=2795630
The downside to the carrier models is that they have locked bootloaders.
So even though you can get root access you wont be able to install Roms or alternate recovery images and such, so you would be stuck on android 4.4.
You would be able to do everything you normally could do on a rooted 4.4 stock rom though.
I have the Verizon model (SM-P905V) and I love it, I currently have a T-mobile sim in it and it gets LTE with no issues.
if you want to be able to root, install a custom recovery and install roms as well as have mobile Broadband you would need the international LTE model (SM-P905) but they are increasingly hard to find for some reason.

Rooting and upgrading software questions - Samsung Galaxy S3 GT-I9300T

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?
