Want to unlock my bootloader + installing TWRP

Hello all,
I am receiving tomorrow my new Samsung S6 and i want to know some things.
- Unlocking bootloader (how to and link?) - have searched a bit and you need ODIN. but what is the best version etc
- Installing TWRP3.0 (how-to) - where to find the latest TWRP for samsung s6
And than one of the most important question, is there a stock android that doesent have any buys and fc's????

Bootloader is not locked on S6 (except AT&T variant)
You can get latest ODIN from here;
http://dl.sammobile.com/Odin3_v3.10.7.zip
If you want to install TWRP on it;
1- Update it to Marsmallow if you haven't
2- Install this TWRP via ODIN;
http://arter97.com/browse/S6/kernel/13.1/g920fi/arter97-recovery-g920fi-13.1-twrp_3.0.2-0.tar.md5
3- Boot up to TWRP and flash this ZIP before do anything on TWRP;

Wouldn't this order make more sense so he had a backup in case something goes wrong?
Also, here are the threads for TWRP and SuperSU for the S6 on XDA:

No, and there probably won't be any for a long time, but there are lots of TouchWiz-based custom ROMs.

so basicly i dont need any customezation? because you telling me there will not be released a custom stock rom? Even a CM13 rom
thats poor services!
Uhm

Correct. The only custom ROMs availability now and the foreseeable future are based on TouchWiz, not AOSP Android or CyanogenMod.

He need dm-verity disabled boot image for working TWRP backups. That's why I suggest him to install this ZIP.

While reading topics on the internet (google)
If you THE smartphone update to 6.0 you do not need to unlock the bootloader. is this correct?
For now i will not use TWRP because there isent a proper ROM for the S6. is this because the exynoss CPU? because QSD cpu's have always the better support for CM..

As I said before, there's no bootloader unlock because bootloader is factory-unlocked on Samsung devices.
If you want root, you should to use TWRP for install the latest SuperSU.
Yes, there's no CM ROM for Exynos 7420 right now. Maybe in future? Who knows...

is there a twrp that works because the original twrp that i download form twrp.me isent working getting a weird issue: recovery is not seandroid enforcing

i tried to install it, used the AP method in Odin.
But when i want to go in TWRP recovery i get the stock recovery! How to solve this issue

I'm having this issue as well on the T-Mobile variant. I have tried the unchecking auto reboot option in Odin and manually going to recovery. When I successfully flash according to Odin, I can't not get past the Recovery is not Seandroid enforcing boot.

Sm-s906l root exist?

Hello I'm starting to think I'm the ONLY ONE with this model of s6 because I've been looking for a root that would work for nearly a month before breaking down and finally making an account here to ask. I've tried Odin but it failed. Every other root option doesn't have my model listed as compatible and I don't want to end up with a brick phone. I'm new to android and I've learned that rooting isn't nearly as easy as jail breaking. Can anyone here help me?

i downloaded https://root-apk.kingoapp.com I use it on my SM-S906L sometimes it fails but i just retry and then it roots! works everytime! I also download supersu and open after rooting, then it removes the kingo superuser for me and then i just reboot.

Here's the stock verizon firmware, it's for verizon but it works with straight talk. There's also TWRP and SU in this package.
(S906LUDU1AOG8)
hxxps://mega.nz/#!XJNwza6L!jZejiTJIchsmbawMLXj-fJ9aJsBDE1VcMw1F5HbTWGo
Flash twrp onto the phone with odin, and then install supersu with twrp and you'll be rooted.

Hi guys! Welcome back to another R&R guide and I've been tricking out the AT&T Galaxy S4 of one of my friends, Laguire, and decided to make this guide. So as usual here comes the requirements, followed by a detailed and noob-friendly guide and download links whatsoever. If you have any questions about the guide, you know what to do underneath. This guide is my riskiest guide EVER, so use it at your own risk. Don't blame me if it dies.
Requirements
A PC running Windows
Your AT&T S4
Samsung USB cable(not neccesary to be Samsung's, as long as it is the same type)
A stable Internet connection
How-To
1. Download files to the correct devices:
-Root ZIP -> S4
-Odin and Recovery -> PC\
2. Connect your device to the PC via USB cable
3. Boot into download mode (Power off > Power and Volume Down)
4. Run Odin
5. Uncheck the Auto Reboot box.
6. Click AP and locate the MD5 file you downloaded earlier
7. Click OK or Start(haven't been using Odin recently)
8. Wait for the first box above to say PASS
9. Power off your S4 and unplug the cable.
10.Boot into recovery mode(Power+Volume up)
11.Tap Install > Locate to the folder where you downloaded the Root zip earlier > Select
12.Swipe to flash

It is probably for SGH-i337 with exploitable old bootloaders (MDB, MDL). Odin and TWRP is a new one but superSU is 2 years old.

How It Will Works ? I Think Not Possible To Install TWRP ! .... Because AT&T i337 Locked Bootloader ... How I Will Install This ?

Sorry guys, I haven't noticed that Laguire's I337 is the old version. Sorry again for the convenience though.

I have a smart question >.< :/.
Does this work for the Galaxy S4 I337..OC4<-- kernel? lollipop*
Thank you!

Does this work with build ok2?
And why is this considered the riskiest???

This seems to be for phones with the MDB and MDL firmware as if you try to flash TWRP recovery on any other firmware, it won't install.

its not warking for me i get this problem : E: Failed to mount / system (Invalid argument) is there any Solution

This guide is for the MDB and MDL bootloaders that can use the Loki doki patch. Once you've upgraded your firmware, there's no going back.

err on the side of kindness

I'm on oc4 rooted, I tried flashing twrp 3230 using flashify...
Big mistake tried to boot into recovery and it said I wasnt using official at&t software and had me stuck until I finally found if I set odin to autostart 1 after flashing the stock kernel it will boot up.... trying to find a recovery to use atm

I thought that the carriers locked the bootloader sometime before kitkat, I'm still using my AT&T sg4. I looped it installing superuser,had a difficult time getting fixed,found a group of F/W files at sammobile that had to be flashed 1 at a time all the way up to lollipop 5.0 then it took an OTA to 5.01. I need to Root so I can clean out all the useless apps at&t installs. I haven't been able to tether my tablet and forgot what files to use to root with.
Did you still have bootloader you use Recovery on,that would be great.

The only recovery you can use is the stock recovery given you are on OC4 which patched the bootloader exploit that allowed TWRP to be installed.

You are correct, AT&T locked the bootloader from day 1 of the S4 launch. However, there was an exploit for the MDL firmware that allowed TWRP to be installed. If you updated past MDL then there's no going back. MDL was Android 4.2.2 jellybean. The only thing you can do with later firmware is root and boot custom TW ROMs by using safe strap for kit kat and flash fire for lollipop.

Hi All,
I have a Canadian S4, SGH-I337M. It is essentially identical to the AT&T version except the Canadian one's bootloader is UNLOCKED. I have been running TWRP 3.1.1-0 to create nandroid backup for YEARS.
Unfortunately, all the sudden I'm getting this error message when I backup, "E: Another threaded action is already running -- not running 1 actions starting with 'nandroid'". It would try to do something and then quit after a minute without creating anything.
So where do I start to troubleshoot this issue? Again, it has always worked in the past! Thank you

Are you sure the Canadian version's boot loader is unlocked? When I go in download mode there is still this line "Write protect enabled" on...

so I do have an S4 on the MDL bootloader, and i've followed all the steps but I can't flash TWRP.
pretty much every link is dead for the i337 root now except for this which doesn't appear to work. if someone is able to provide the loki, motochopper, and other necessary files for this device so i can get this paperweight loki'd, that would be sweet.

[Q] Root Canadian galaxy s7

Hello i recently bought a galaxy S7 SM-G930W8 (Canadian / BELL Mobility) and its veen updated to the latest it can which is android 8.0 (oreo) and id really like to root it without havibg to change my stock rom actually id just be glad to get it rooted also the security patch is up2date as of july 1st 2018

The W8 is an exynos model so the bootloader should be unlocked, flash twrp through odin, do a factory reset, reboot to recovery from TWRP itself, flash no-dm-verity zip which should be in your memory card, if you don't have one use mtp in TWRP and copy it to the phone, then install magisk zip and you should be good to go. you can find those two zip files in the forum or just a simple good search.

Did you have any luck rooting the SM-G930W8 on 8.0? I just acquired the Canadian S7 and I'd like to root it, but I know it's different from the American S7's, and all I can find is how to root the Canadian S7 with Nougat.

It doesn't matter which carrier it is, what matters most is the chip and the bootloader, the Canadian variant uses the Exynos soc so the steps are the same just like the international model. Start by unlocking the bootloader and installing a custom recovery, download TWRP for herolte, on your phone enable developer options, then make sure OEM unlock is checked, turn off your phone and boot into Odin, then flash the TWRP image, make sure to uncheck reboot after flash in Odin. Once flashing is done, manually reboot your phone and make sure to enter the recovery mode, do a normal factory reset, the one that asks you to write YES to confirm, then reboot to recovery again, plug your phone to the computer and copy the latest magisk zip then flash it, and that should be it basically.

I thought the Canadian variant with Exynos already had an unlocked bootloader? There are already instructions on how to root my exact model, but the assumption is 7.0.
I have rooted other phones before, and sometimes the requirement for a version of Android before rooting is very specific. I have no idea where to start to even verify whether the bootloader is truly unlocked, whether or not I can proceed with rooting despite having a different Android version (in my case, 8.0, not 7.0), etc.

Sorry there, I guess the correct description would be tripping knox rather than unlocking the bootloader, since you're already familiar with the process then I can tell you its totally the same, nougat and oreo aren't different enough for anything to change, allow OEM unlock, install twrp, do a data wipe, reboot to recovery again, install magisk zip and you're good to go. You might need to flash the dm verity bypass before magisk, that's another zip you can download as well.

Can only install official binaries message when flashing TWRP with Odin3 on A750FN U4

Hi, I'm having a lot of trouble trying to install a custom recovery. I had it working a couple months back but wanted to go with official again for dumb reasons and now i want to go back but it won't let me flash TWRP, i can't find a TWRP specifically for this version either. It's Android 10 with March security patch.
I hope someone can help me.
Thanks.

Please only create one thread per topic. I've removed the duplicate thread you started on this topic.
As far as your issue goes, I don't actually know much about Samsung specifics, but I believe that particular message means you haven't unlocked your bootloader. You'll need to do that before you can flash custom stuff.

Like I said, I'm not 100% on Samsung shenannigans, but have you checked to verify that you didn't lock the bootloader as a part of flashing the stock firmware?

OEM unlock toggle in Developer's Options

Hi ¡...
1. You have to reinstall via odin the latest version 9 (AP, BL...etc)
2. On reboot do the entire TWPR flashing process for android 9
The current problem is that there is no TWPR for android 10.
Cheers
