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

Don't want to have to choose between root and warranty...

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 it possible to re-lock and unlocked bootloader?
I know updating should get rid of an unlocked bootloader, but I still get the warning screen on bootup.
Reason I ask is because I had it unlocked, got an OTA update from Verizon for kitkat, and soft bricked my phone. Got stuck in a boot loop with the unlocked bootloader warning message.
I just flashed back to 4.0.4 using RDS Lite 6.1.4. Id like to reset the boot loader to locked before updating to kitkat again.
It's not possible to re-lock. I've updated to KK and can confirm that the BL is, in fact, still unlocked.
I have read somewhere that when you unlock the bootloader, it actually physically blows some kind of physical fuse. or maybe I miusread it.
Someone had made a special logo.img you can flash to get rid of that message.
Although if you really want a locked BL phone, I'd be more than happy to trade you.

Not that it helps, but in Australia, we do not get the nasty warning message after unlocking the bootloader. And I think that the phones are actually sold with an unlocked bootloader.

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..

I think this should be possible now with Quadrooter vulnerabilities?

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
I really hate the stock boot image on this phone because the phone boots up before the animation is even done. I would like to flash a custom boot.img, but this phone is covered under warranty and I don't want any visible traces of modification if I have to send it back. Also, if possible, a guaranteed way to relock it or have it say "relocked" in bootloader would be a good alternative. I MISS ROOT SO MUCH.
No. Once the bootloader is unlocked it's a done deal. You won't be able to do anything on the phone unless you unlock it.

****. thanks for replying. ill have to wait till the warranty runs out
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. I am using this zip to flash Stock ROM and lock bootloader.
But when I run the "fastboot oem lock" command after running all the commands, I get the error: "Still require signed boot.img".
And the bootloader is not locked.
Please help me out.
What reasons are there for wanting to relock? have you decided to go back to stock and can't use android pay etc?

I want to sell it.
ah right, In that case I can't help as I'm in the same situation, can't relock however I am keeping my device, I was going to suggest Magisk to hide root etc but obviously not what you're looking for now

After fastboot oem lock
Flash boot , oem and all system images then again type fastboot oem lock.
It works for me..
Just so you know, relocking the bootloder does not restore the warranty. You need to let the person you are selling it to know that the warranty is still void. Lenovo keeps track of devices that were unlocked, so even relocking it will not revalidate the warranty.

You mean to say once i ask for unlock code my warranty is voided even if do not unlock after that

Possibly. Unsure if it is voided upon simply requesting the code or only after actually unlocking it, but it is definitely voided upon a successful unlock.

Sure, I will let them know. But locking can still benefit if the service center guy only checks for bootloader unlock status.
