New Nexus 7 wifi. I've unlocked bootloader, rooted, new recovery, new 4.2.2 ROM.
I notice on some of the toolkits I'm able to re-lock bootloader. Assuming I'm not returning it to stock, is there any advantage to doing this?

Any advantage to relocking it I would say no.. I believe I remember reading (and i could be totally wrong here) that there is a counter that gets changed when you unlock it.. I would guess so they could deny you warranty if they wanted even if you flashed back to stock and relocked it they would know. But I unlocked mine 15 minutes after opening it up and flashed TWRP with fastboot then installed a new rom and faux kernel and relocked mine just to see if it wouldn't run the non stock recovery or a non stock rom and kernel.. it still did. I leave it unlocked.. im thinking the whole locking thing is just a warranty scare tactic
And if you relock the bootloader, you won't be able to use fastboot anymore...

Extremely untrue. You can use fastboot all day long to flash stock roms, recoveries and such with a locked bootloader. That is the entire purpose of fastboot. You just cant flash custom recoveries, custom roms and such. Fastboot itself it completely intact and useable. It is the Nexus stock flashing tool. That is how you UNLOCK the bootloader in the first place. Even if you use a toolkit, it is merely a gui that is still utilizing fastboot for you in the background.

Same, I unlocked mine the moment I got it. Also the lock isn't really a warranty scare tactic but rather a security feature, with it locked (which can only be unlocked via fastboot anyways) would prevent the system from replacing the components such as system, recovery or bootloader that wasn't officially signed.
It's also a way for warranty to only be applied to software or components that they are actually responsible for, since damage caused by something they don't make wouldn't be covered anyways.
Also even if you did have it unlocked, and the device was suffering from a hardware-based manufacture defect, it would still be covered under warranty, even if they deny you at first, would just have to push the nature of the defect. (And besides, far as Nexus devices go, would seem as if they were sold to be tinkered with).

what about Locking Bootloader on MultiROM ?!?!?!
Good Afternoon All,
Do you think it may be possible that we can get root access without unlocking the bootloader - I'm a little reluctant to unlock the bootloader because of the QFuse blowing.
The QFuse does not blow when you unlock or relock the bootloader. Many reviews and Android news sites spouted that nonsense without having tried it. There are many screenshots of Google CSRs saying that they don't know what the QFuse is for, but unlocking the bootloader/rooting/alterring software is fine as long as it's not so bricked you can't reflash stock images before sending it in to them.

+1 the QFuse status didn't change when unlocking the bootloader. The media exaggerated about the qfuse and nothing has happened. Everything about the phone still works properly.
Thanks very much, I wasn't aware of this, I should read more. Awesome news.
But to answer the first question.
Very few people put in effort to root a phone with an unlocked bootloader, not matter what fuses are blown.
A phone with an unlocked bootloader has root by default.

last i read you have to flash a kernel in order to root the phone therefore you need to unlock the bootloader to do so, i would like to just root myself but i don't know if you can.
No answer?
I would like to get Root on my Nexus 6p but currently do not want to invest the time for full bootloader unlock/fresh install.
So... I will ask again, is it possible to get Root access on Nexus 6P with stock kernel and leaving bootloader in factory locked state? If yes... are there any guides to do this?
Why people are afraid to unlock the bootloader? Nexus devices don't lose the warranty when you unlock it, you can also lock it again.

The answer is no.
To do what you want, someone would need to develop and exploit.
There is no motivation to do that when all one has to do is unlock the bootloader.
On phones where a bootloader unlock exists, root methods require unlocking the bootloader.
This is to install a custom recovery so yiou can flash SU.
Unlocked bootloader = root, no matter what.
You will need to invest the time and backup your device.
@TS, did you read the unlock/root guide in general section? It clearly states you need an unlocked bootloader + custom recovery to root your device..

DOA.
But nobody is going to put in time and effort.
What is the point? Unlock the bootloader and flash. It does not void the warranty.
There is even a defined method to get the monthly security update.
With the exploit, it will only work until the next OTA patches it.
I was hoping to root without unlocking the boot loader also. I am definitely not willing to do this since I believe that is what wrecked my previous 6P. It was fine until I used Nexus Root toolkit. I unlocked the boot loader, installed TWRP and rooted then minutes after this the phone locked up, rebooted and was stuck in a permanent boot loop. I couldn't get into recovery or even install any recovery. That phone is currently at the Huawei repair center in Texas and they are sending me a new device. They believe the internal ROM failed and I have suspicions of everything I did with the Toolkit did this. I am afraid to try it on my current 6P that I got from a friend. I have no root now and the phone is massively stable. 400+ hours uptime with no reboot and no slowdowns. But if I were able to root with no unlocking of the boot loader or installing any custom recovery I probably would do it. I hate that I am scared to do all that again with this other phone haha. Sorry for sounding paranoid but ****, see where am I coming from?

As good as toolkits are, put in the extra time and avoid using them because you are never in full control of what is being done to your device. Take a little extra time and learn adb and fastboot. It's actually really simple and you can get so much done without the need for using a toolkit.

I have tried that only a few times. I understand what you're saying. I guess convenience can be more destructive. :/

In all honesty it's not even more convenient. Once you've used the command line you'll never go back to a toolkit. It's actually easier, much faster and you have way more control over what you do.

Use Helium app for individual apps backup. Worked great to backup a few apps/data when I changed from one Nexus 6P to another. Might be a bit buggy to get working to get the backup, but after that everything is fine.
you can do it with KINGROOT
Hey guys
Has anyone had warranty work done after unlocking your bootloader and relocking?
Half the attraction of this phone was the outstanding two year warranty. But I need my root access.
Thx

If you unlock the bootloader using the unofficial method, you could always relock the bootloader before sending it on warranty (depending on how broken it is)

Well that's what I'm assuming, but I don't know if there is some kind of permanent bit like uh Samsung Knox that can tell them it was unlocked at one point.

On a bootloader unlocked device, boot into the stock recovery, select the bootloader option.
Look at the last entry - device state. On a virgin phone it says locked. I'd expect it to say something else if the BL is unlocked. Further, does relocking bring it back to locked state, or something else. If something else, then it would seem they can check if the BL was unlocked.
I haven't had time to mess with mine, will be this weekend's project.

I Asked this in one of the other unlocking topics before.
When it's locked, it says "locked".
When it's unlocked, it says "unlocked".
When the bootloader has been re-locked, it says "locked" again.
Besides this and having submitted for the official bootloader unlock (when it was available), it's unknown if there's any other way that ZTE can tell if you are/have been bootloader unlocked.
^^Thanks.
Valid point. Could be some hidden fuses that get tripped - like what samsung uses.
Highly unlikely that they can tell with the unofficial method.

I'm not 100% sure but I think there is nothing like Knox in the Axon 7.
Is there any possible way to re-lock my bootloader and get back the warranty of my device?
Some buddy posted in my Kernel's thread that you should be able to do:
fastboot reboot oem-lock
But idk if this has some kind of sense and after unlocking BL your device is marked as non-appliable for warranty in Moto's database.
https://firmware.center/firmware/Motorola/Moto G4 Play/
Go to here and find right for your moto g4 play edition. And flash.

Don't, after unlock you lose the warranty, if you re-lock after, the bootloader status don't go back to when you buyed the device (In the same way it says unlocked in the bootloader, it also says that it has been relocked), so it's useless.
And like facuarmo said:

Yeah, you can't get your warranty back once you've unlocked the boot loader. The fastboot command mentioned above can be used to re-lock your boot loader but that won't bring back warranty of your device.
Hi there! I've always been a Samsung user and I'm familiar with chainfire rooting method, Odin, the damn knox and all the tools that people need to achieve the beloved full control of our phones.
Let's go straight to the point: I need to buy a new phone for a friend of mine and the P9 Lite seems the most complete and suitable but I've read that if you unlock the bootloader and root it you obviously loose your warranty. The phone is unrootable by flashing a fresh OS image, but the bootloader will stay unlocked, tripping the useful warraty.
Is there any damn way to revert everything to stock in case there should be the need to send the phone to the customer service?
Thanks for the infos!

You can relock the bootloader if you reinstall a stock rom and revert to stock recovery, just fyi... Also there have been reports that the warranty is not void if the issue was not caused by a faulty software. Also if you are new to Huawei, be careful. And READ! A lot of people don't read, and mess up their phone...
Instead of making a new thread about the same issues I'll pitch in here too. What is the safest way to root and unroot in case of warranty? LIke the OP I came from the Samsung ecosystem too but I get the feeling if I don't at least ask about Huawei's one I'll probably **** something up.

Simply flashing stock rom will lock bootloader but Huawei have your data of unlocking bootloader.

Huawei says they "could" apply fee on unlocked phones. Maybe relocking it restores warranty? I tried to ask them but damn Chinese they don't reply.
They could, but the chance of that happening is really low, especially if your device is 100% bricked, and it needs a motherboard swap

If it's hardbricked and bootloader is unlocked and the problem is not related to bootloader or a process you made that requires unlocked bootloader, I think they won't fee you because it has nothing to do with bootloader. But of course a company will always choose cheaper way. If a phone goes download mode or fastboot mode it's already saved anyway.

I wish... I can't seem to be able to save mine, even though it shows up on fastboot on the pc. The phone itself won't turn on at all. I can't seem to lock the bootloader either, anything I flash now seems to have no effect. I just hope the Huawei service fixes it.

If you have access to fastboot mode, you can flash anything. You dont have to flash an img permenantly if you want to save your phone. Use
Code:
fastboot boot boot.img
you can boot your recovery without rooting your phone. You can even open your custom recovery and flash your system.img or stock boot.img.

I tried fastboot flash boot boot.img (and similarly, recovery.img, system.img, any partition I could flash, multiple times with multiple files) but the phone did not boot at all. Not even into the bootloader nor recovery. It was completely unresponsive. Now the phone is not in my hands so any suggestion is too late...
