How to unlock bootloader of Galaxy note 2?

So my sister has an Attt Galaxy note 2. I want to format her phone and install aokp or cyanogenmod on it cause they are smoother and faster roms. I searched on how to unlock and root the Galaxy note 2 but i've only found a bunch of guides showing how to root the phone, i haven't found one telling how to unlock the bootloader?
does anyone know how to unlock the GN2 bootloader, or is it already unlocked?

Surprise no one has answered. You can't, and you don't need to.
What firmware is the phone on now?

what do you mean you can't? Are samsung phones different somehow? I can unlock bootloader on my Nexus 4, my bro's Moto g, and my other Bro's Lg Optimus G, so why can't i unlock bootloader on Samsung Galaxy note 2?
i've never used a samsung phone before so i'm not sure if they differ somehow.
So i don't need to unlock bootloader to install aokp or cyangamod? i only need to root and install custom recovery? I think her phone is on android 4.1.2 or 4.2 i forgot which one.

Samsung does not consider your phone yours as these other manufacturers.
If she has not done the most recent Over the Air update to 4.3, it's probably on 4.1.2. The latest OTA installs Knox security. You dont want that.
There are some good choices in the http://forum.xda-developers.com/galaxy-note-2-att/development
You don't need to root either. If you do install, it will get overwritten since it's installed in the /system directory. ROMs replace the /system directory.
Just install custom recovery, follow ROMs install instructions. Verify with the thread OP if it requires the 4.3 leaked bootloader.

I really appreciate the help . i posted on android central and this forum but no help until you posted so thanks. I guess samsung phones are different. I was also told that you only need to back up EFS files on samsungs phones only and NOT on Nexus 4, or Moto G right?
Also, you said you can just install custom recovery but don't you need to root phone to do that? and the most roms like aokp comes rooted by default right?

Sorry, started replying back last night and got sidetracked.
Yes no need to root, pre-custom recovery. They are totally different. Root (superuser) is a file and app.
Custom recovery replaces the phones built-in Android recovery.Two "versions" TWRP and Clockworkmod. Both work well. Some ROM installs will suggest using a certain one.
ODIN will root the phone.
That file is here.

Most ROMs do have root incorporated.

odin can also flash roms and install custom recovery images right? i can just flash roms and recoveries using adb on the GN2 to flash roms also?
The technobufallo guide kind of made no sense since the guy used odin to root the phone, then used odin to flash custom recovery, then used it to flash cyanogenmod, which is pointless since like you say above, custom roms comes with root preloaded.
also my sister asked att to unlock her phone and now she's using tmobile with the phone. Would flashing any roms also lock the phone and prevent using tmobile sim?

INSTALLING TWRP 2.6.3.1
Download
http://goo.im/devs/OpenRecovery/t0lteatt/openrecovery-twrp-2.6.3.1-t0lteatt.img.tar
- Run Odin3 v3.07.exe
Download Link http://www.mediafire.com/download/772dlmuaxfgm0x2/Odin307.zip
- Put your Note 2 in Download Mode
Entering download mode is very simple. First you will need to turn off your device. Once it’s off, you need to press this button combination: volume down, power button and home button. Keep them pressed until the download mode shows up. Once you’re there, you will be required to press volume up to enter the download mode or volume down to cancel and reboot the device.
Plug into a RELIABLE usb port and a RELIABLE usb cable (preferably the white Samsung cable) and wait for it to show up in Odin (COM5 or something like that)
- Click the PDA slot in Odin and locate the openrecovery-twrp-2.6.3.1-t0lteatt.img.tar that you downloaded.
The filename that goes into the PDA Slot is openrecovery-twrp-2.6.3.1-t0lteatt.img.tar
MAKE SURE IN THE OPTION AREA ONLY AUTO REBOOT AND F.RESET TIME ARE CHECKED!!!
- Click START and wait. It will complete and reboot.
Just install this ROM
http://forum.xda-developers.com/showthread.php?t=2568537
It's multicarrier so TMO is supported. It's rooted already.
Right above the Vipers Audio banner, on the left is a click here to show content. It lists all the features. I don;t think she's going to need more than this ROM right now.

OK thanks alot man and thanks for taking the time to write all of that to help me :victory:
I was going to install aokp or cyanogenmod since she' been complaining about her phone being slow and stock touchwiz 4.1.2 is already reptty slow in itself. BUt she said she wanted to use s-pen features and especially multi window for her work, so those aokp and cyan roms were out of the the question. I still think if she wants speed, she needs aokp or cyanogenmod though, but i guess a lot of people those the touchwiz features

[Q] Doubts in rooting

So far I've had only Samsung phones, which were rooted by flashing a zip file through the built-in recovery (containing signed SuperSU).
Now I have a 2013 Nexus 7 and I'm looking at the rooting guides and I see bootloader unlocking, flashing custom recoveries and a lot of other things which personally confuse the hell out of me as to why are they needed.
So I wanted to ask if there is a way to just flash a zip file with the SuperSU (and buzybox) app like how it's done on the Samsung phones? Or if there is a method that doesn't require replacing the stock recovery / flashing ROM components?

If anything its easier than any Samsung device but the thing is don't Root if it confuses you at least until you understand how to do it there is tons of guides online

That's kind'a my question, it's not that I don't know how, I just don't get if all the side-stuff in 90% of the guides is actually needed, so I asked if there is a way to just get SuperSU working without any custom-recoveries or other side-things.

To my knowledge, you need to have a custom recovery to root it. Unlocking the bootloader helps with this, as it ensures recovery and root sticks.

Or, just use the Wugfresh Nexus Root Toolkit to unlock and root.

I was in the exact same position as you four days ago, up until then the only android devices I had owned were the Samsung Galaxy S2 and S4. It is quite different to the rooting process on the samsung devices but just as you did with the Samsung devices you will learn as you go along. My bootloader is unlocked, rooted with a custom rom and it was pretty easy to do

A sideload would only be needed if you didn't dump SuperSU on the phone first.
Unlock bootloader
Flash TWRP
Flash SuperSU
Done

Get wugfresh's nexus root toolkit. It's made for the novice in all of us.... Works great, self updates, awesome help section.. Look into it.. It's made specifically for the nexus line of products

Thanks for the replies guys, but noone seems to say what is the minimum that neds to be done for rooting.
I'll re-ask my question in a different way:
When rooting, does the bootloader always have to be unlocked and a custom recovery always needed to be installed?

Bootloader needs to be be unlocked, but can be relocked after rooting
AFAIK, you can use stock recovery, but custom offers better options/control over the situation. Most roms/kernels are flashed via twrp or cwm..... You can flash through rom toolbox if you choose to stay stock recovery

You can use Towel root to root your tablet in about 30 seconds. It'll also unlock your bootloader for you.
Cousin recovery is only needed of you intend to flash kernels and Roms and the like. If, like me, you only want root for installing things like xposed then you don't need to bother with one.

Yes, all the steps that are listed are required for rooting your Nexus. I understand what you are asking and I was also hesitant at first, but it was super easy to root and I didnt use the WugFresh took kit I manually rooted mine, following Zedomaxs Video tutorial, that way I could stop and Pause it at every step to make sure things were happening as they should here is the link
https://www.youtube.com/watch?v=X1cD-JXRGX8

I confirm towelroot works on the 2013 nexus 7. After rooting unlock bootloader with app from google play. This method does not wipe user data or need a computer at all. And if root is lost and the towelroot exploit is patched with the next os update you can reroot the old way.

Rooting questions (kinda newb again)

I have unlocked my bootloader, I have gone through the process of installing TWRP RC1, I have also installed SU 2.79 as guides have shown to do. I have also installed adaway after rooting, as well as titanium backup.
What is left to do now? I have read that if I stay on stock but rooted, when a security update comes out next month and I take it, my device turns into brickmode. I don't intend to stay on stock, I am taking the time to learn all the ins and outs of each rom that exists currently and trying to make a decision which one I like best, and especially what kind of challenging process exists for flashing the rom as well as putting TWRP back on then SU, and the confusing part about doing the vendor image. So yea, still learning. The last time I rooted and flashed anything was LGG3 days, so it's a learning curve again.
Am I supposed to be using a flash drive for anything? Or is that not needed if following the installation process for whatever rom is out there.
Thanks in advance, everyone has been very helpful so far.

There is no need for a flash drive. You can easily disable OTA on stock, and there is no need for a custom rom. In fact, I am rooted on stock. Also, the OTA should not be able to go through while rooted but I have seen myself that it does work surprisingly. My guess is this is because of the dual partitions, but no, you will not get bricked if you accept an OTA. The worst that would happen is that you would lose root. I'm guessing this is due to the dual slots. The OTA overwrites the other slot and swaps it on reboot. You should be able to just get in again but without root.

And if it does fail you can download the full OTA from google and install it with TWRP or adb install it.
Turn off updates in dev options. A couple of people have gotten hit with big data bills from it downloading over and over.

I'm unlocked but not rooted. I installed Franko kernel but need to be rooted to use his app. I'm trying to figure out root yet stay stock for now.

What is the best way to stay up to date while keeping TWRP

Just got my S9 all set up just they way I like it. But part of the way I like it means knox has been tripped which means no more OTA updates for me. Is there a preferred method to keep my device up to date without having to go through flashing TWRP and all those other steps some of us like to do?

Only by flashing a new custom ROM from TWRP, if you are stock and want to keep stock you'll have to flash the updated stock with ODIN then flash TWRP again afterwards

First I installed TWRP to give me a really nice backup and restore solution
Then, I used TWRP to flash a custom rom and also Magisk
Then, I use Magisk to install YouTube Vanced (no-ads)
Magisk also provides a root-like access for me to install ad-away and remove any bloatware that I don't like
Finally, I sometimes experiment with different things through the time I have the phone

Which rom did you choose?

Soldiers ROM. It was just a simple no nonsense easy to debloat ROM

some questions ^^

hello guys! im rooting phones some years now but first time im afraid to do that i see alot hard bricks etc so i want to ask
i have the last firmware now global (phone is global 2) if i put twrp for magisk i have to stop upgrade the phone right?
second. i never liked stock roms so again... if i put twrp i can flash whatever rom i want or there are steps every time so i wont brick the phone? thank u guys for ur time

dont do it

For rooting stock ROM, you can flash twrp and flash magisk but you should be careful to pick a recovery which is for android 10 and also not for CFW.
For flashing custom roms, you should read the megathread. It's not very complicated and if you follow the exact steps, you will not get bricked.

It's all explained in the megathread, sir. For custom ROMs you need CFW recovery but for you to be on CFW you need to flash CFW with a non-CFW recovery.
Best way to do it is in the CrDroid post.
Have a nice day!

tl;dr: flash Android 9 then megathread

i tried rooting with magisk on latest android 10 miui 11 , basically you will fail safetynet and basic integrity will fail as well you can try to hide fingerprint with magisk busybox and props module and type su to give termux root access and edit fingerprint to pixel 4 but it's not guaranteed i don't know if there is google attestation hardware in begonia anyways you can try.
here's a pic from pixel experience safetynet.(not rooted)
