I've been combing the forums for a couple of weeks trying to get information about upgrading my old note 4 (Verizon, MarshMellow). I wanted to use the Lineage OS 18.1 but I can't find a way to unlock the bootloader. I've tried every method without success. None of the temp root programs seem to work. Odin gets close and then fails at the end. Same for ADB. I can't seem to get a clear answer to a question: Do you have to downgrade to 5.11 before attempting any of this? If so, how is that done on this phone? It is alluded to but not clearly stated anywhere. I'm willing to do the legwork, I just need a clear starting point.
Thanks
To unlock a device's bootloader it's NOT required device's Android is got rooted.
To flash a custom ROM like LOS you have to find a suitable custom Recovery for your device and flash this as 1st thing of all things.
Thanks for the response. That's what has been confusing. Most of the procedures I've read (some of them older) state the the first step is to temp root with Kingroot or similar. These don't work on my phone so I haven't gotten very far. Others want you to unlock the bootloader first. Same problem, can't find a way to to that in this phone that works. I'm pretty OCD so I'll keep searching.

[Official] Note 4 Verizon Bootloader Unlock
Enjoy. Don't forget to thank beaups too, he discovered the eMMC backdoor and exploited it! UPDATE: [8/2/16] I have recompiled the binary to fix issues with older ROMs like 4.4. This should fix all the issues with "This is for samsung device...

If you are using an SM-910 with a locked bootloader, like the 910V, then the answer is an unequivocal YES you must first unlock the bootloader before you can accomplish anything substantive with it, and to do that YES you must also downgrade to 5.1.1 to root it and unlock the bootloader. And your device must have a CID 15 eMMC chip to achieve any of this.

I just had a quick questions about rooting.
I rooted my phone with motorchopper and things have been working great. Got rid of all the bloatware I didn't need as well as gave my device a quick clean. I've had little to no signs of lag(made in Korea). I'm new to the whole customization route. This is my first smartphone and I couldn't be happier with it
1. I rooted my phone successfully, however, I have heard somewhere else that the device needed to be bootloader unlocked before it is rooted. Now, motochopper, allowed it to find an exploit in the device. Is this, in any way, harmful for the phone if it finds an exploit? Most likely not, just curious. Dumb question
2. Does the device need to be bootloader unlocked before I am able to flash a custom recovery, ROM ect.? If the device turns out to be bootloader unlocked later on and released can I flash custom recoveries, make backups and use most tools successfully through ROM Manager? Or would it be best to do it through Odin and do things manually? Where would I be able to find essential files? Is odin specified for a specific device? Just curious
3.What ROM's would you recommend. Cynogenmod? I just want something that is lightweight, stable and functions well throughout the device. Where would be a good source to find good roms?
4. If the device is already rooted can I just start flashing custom recoveries, ROMs ect? Or would someone need to release an unlocked bootloader? How does unlocking the bootloader work? What are ways to do it? Flashing a file or doing something else. Idk..just curious I may be wrong.
I just want to know some good methods to make sure I don't brick this device. Of course backing up and recovering would do well. I've heard clockworkmod is one of the best custom recoveries you can use.
Thanks, in advance, for you help.
I just need some help. I have been using a guide which was working perfectly at first but then it failed due to a faulty battery. Got a new battery and its still not rooting properly. If anyone is will to share some guidance I would really appreciate it.

Why would root fail due to a flauty battery?
Install a custom recovery first then flash SuperSU. Use Odin. Check YouTube. Flash twrp. Then flash SuperSU. You have a custom recovery and root. If you want only root try alps like kingroot.
The faulty battery didn't have enough power to turn the phone back on after the root made it reboot. It just kept putting it into a bootloop.
The guide I was using said to use Kingroot to temproot it (it rooted once and then got stuck in the bootloop, which is were the phone is currently now) and then SuperSU to perm root it but now I can't even get more than 55% with Kingroot before it shuts itself down.
I thought the bootloop was my fault from ****ing with it so I flashed twrp onto it and it now has a little broken lock that says custom over it but the twrp commands don't come up so I still can't put the ROM on it.
If your on 5.1.1 better use kingoroot for a high success rate and after that you NEED to unlock bootloader first and then flash twrp. If you dont unlock bootloader you cant flash twrp.

Why would you use Kingroot or Kingoroot if not to unlock the bootloader? Neither will give you a stable root and both have the potential of calling home to China with your personal data.
If you need to unlock your bootloader there are threads in this subforum that will tell you how to do it. However, I'd strongly suggest that you do some serious study into what you're doing and why before you attempt it.

My roommate from college was telling me to do this and was helping me but he did a half as way of explaining this stuff so thats why I came here. The Kingroot and Kingoroot is to unlock bootloader? I thought they were for a temproot? Not to be a pest but would you be so kind to explain?

You need temporary root at which time you can deploy the exploit that will unlock the bootloader and give you full root. That's what Kingroot or Kingoroot do for you. What they may or may not do for you is give your phone cooties and call home to China with your personal information.
Can I hold your hand and walk you through rooting your phone? Yeah, I could, but I won't. The guys that developed the exploit think it's a good idea for someone to have at least a clue as to what they're doing. I happen to agree with that. Rooting is fairly safe for your phone so long as you're willing and able to follow directions exactly.
Read up on the process of rooting. There are three or four threads in the general section that tell you how. If you think you're up for it, do it.
I'm making a barely educated guess here, but my understanding is that the 905V and 900V (Note 3) are very similar so it occurred to me to try the Note 3 bootloader unlock on the 905V after getting my hopes up regarding [ROM][P905][UNOFFICIAL] LineageOS 14.1 then installing TWRP on my rooted 905V running NK1/4.4.2 only to realize that the bootloader was locked and I couldn't run TWRP.
My CID did change and has stayed modified after using that tool and rebooting, but I still cannot run TWRP. This means that the CID change was good, but the bootloader is still locked right? Is this idea fundamentally flawed, or do we just need a different CID for the 905V and a modified "unlock_n3" could get the job done?
I'm reaching out to ryanbg and beaups to see if they can help or provide feedback.

That is specific for the N900V bootloader. It will not work with this device. You're lucky you didn't brick your tablet. The unlock doesn't work for this device.
Hi there,
I found there is a thread describing how to root the US/Chinese model without unlocking the bootloader -
https://forum.xda-developers.com/axon-7/development/wip-axon-7-root-bootloader-unlokced-t3441204
However it mentions that this'll brick the European model because of the included TWRP version and unfortunately I'm on a ZTE A2017GV1.0.0B08 (Android 6.0.1, Kernel 3.18.20).
Is there any news if this can be done now with the international variant -
I'm not interested in a custom ROM or updating Android, I'm happy at the moment with the 6.0.1 version I have, but really would like root for xposed framework, Titanium, Tasker ...
Is there a different TWRP version that can be used or is it not working due to the ZTE's signature key used?
Alternatively is there a way for the A2017G to re-lock the bootloader that's 100% working/safe, if you don't apply a custom ROM?
Thanks a lot for your help!

Hi.
It didn't really answer the question : Is unlocking necessary to root, or can we root without unlocking ?
Every tutorials founds all follows the same paths : Unlock first, then root. But why ? is there a reason for that, or is it just a "since i'm rooting, let's unlock it while i'm at it" thing ?
(edit : Sorry 4 my english ... i hope i've been clear enough)

Hallo Marcus
Danke fuer die Antwort -
Maybe I didn't fully comprehend the thread - I was under the impression that it bricked some A2017G, while not others and didn't want to take the risk.
Reading through the instructions - which of these steps did you take (and in what order)?
I read it that you do not need to flash TWRP? So can I just root the phone without bricking it and all is good as long as I stay with my 6.0.1 B08 version?
I understand the instructions as
- boot into edl
- install Qualcomm driver
- run axon7root to already root the device (backup seems to be done in the next step?! according to instructions).
However there is no axon7root version for the A2017G (B08) as it was removed due to TWRP?!
All I can find is the axon7backup tool (would you actually do this before you run the axon7root the first time?)
If you run the axon7root, did you do 'axon7root.exe -p 4 -b'
so that it only flashes the boot.img (not TWRP recovery) and therefore this is safe?
Sorry for the long essay, help is really appreciated!
Hey, sorry for the delay.
I am quite busy. I really don't know the procedere anymore. It is a long time ago. But if you would give me some time, I will have a look on it and will let you know. But why won't you unlock your bootloader? Without unlocking not everything runs as it should with unlocked BL.
OK. I will let you know.

Theoretically, yes, you can root w/o unlocking the bootloader. This is how things are done typically with certain manufacturers (LG, Samsung) that rarely offer BL unlocking. To be able to flash TWRP on a locked BL is even more difficult, as it would require a BL-level exploit. The reason that's not an option here is the ability to unlock, which precludes such development.
Hi Marcus,
Thanks a lot, that would be really great.
Regarding Bootloader unlock - I didn't buy the phone in the EU, hence my warranty would be void if I unlock it. And my warranty even comes with screen replacement (not that I ever cracked a screen, but there's always a first).
I have to admit that I'm tempted by Lineage OS, but for now (as I just bought the phone) - if there's a reasonably safe way to root without unlock, I'd prefer to just root and then maybe in a year's time or so switch to Lineage OS...
For now I managed to have my phone recognized as QUSB_BULK and I can boot into edl.
I was trying to use the axon7toolkit (1.1.1), but for whatever reason I cannot use it in commandline mode (maybe as there seem to be different versions, or maybe cause I am on Win7 32bit, no idea).
Any help would be really great!
Hi jeboo, Hi Sn8k,
Hope above explained my motivation, regarding root without unlocking - there's a thread about this
https://forum.xda-developers.com/axon-7/development/wip-axon-7-root-bootloader-unlokced-t3441204
HOWEVER there are two problems:
1) The bootloader can stay locked as it's using a signed version of TWRP, which can brick your device (A2017G)
2) The linked axon7root.exe is not for my device (A2017G B08).
Having said that, some users have been successful with rooting this version, so there seems to be a way, if you get the steps right.

You can't. Don't even try it if you don't want to face DFU...
Just use the same app that the phone comes with, I think it's WeShare or something like that. It should let you transfer all of your crap via a LAN wifi transmission (If you use a 5GHz hotspot it'll be fast as heck).
Or just unlock the phone. But don't relock it if you do, because you can make a huge mess
I have a Sprint Galaxy S7 Edge SM-G935P running on 7.0 and have been looking for a way to root my device. I was looking around the cf autoroot website and you can customize your own root package for your device. They list my device on there and it lets me build an odin flashable root package for it. Will this work? Or will it brick my device? It even lets me pick the exact device, and android security patch level and build version that is currently installed on my phone. Ive read that this phone has a locked bootloader that is locked down tight and its hard to get unlocked. This says
BOOTLOADER UNLOCK
If your bootloader is not unlocked, depending on the device, it may be automatically unlocked (wiping all data), flashing may fail, or the device may brick altogether.
So will it unlock my bootloader and root my phone? or will it not work? I havent seen anything about this method when i just google "sprint galaxy s7 edge root" and i dont see anything about it on this forum, i figure if it worked that more people would be talking about it and using it. Any advice? should i try it? it also gives links to the stock boot and recovery images, and i also have a copy of them saved on my pc.
give it a try, the worst thing that will happen is you will brick your device. Then you will have to play dump and get it replaced.
