Locking bootloader question - Nexus 6P Q&A, Help & Troubleshooting

I have unlock and rooted my phone at one point and returned everything to stock image two years ago. Recovery is the android recovery. The Nexus 6p had multiple OTA upgrades from Android 7 to 8.1.0 . Do I need to flash the factory image or can I just lock my bootloader via fastboot ?
I'm going to sell the phone and I was thinking of locking the bootloader before sending it out.

You can lock the bootloader since you're using the stock rom. Please be sure to remove your email accounts from the phone prior to selling the device.
Factory Reset Protection will prevent any new buyers from using the device without inputting your email and password credentials to first sign into the device.

Perfect ! So it doesnt matter that it's been updated multiple time (OTA) as long as it's stock rom ? Sorry I dont want to brick it prior to sending to the seller. Appreciate the respond !

Who Has an Unlocked Bootloader?

Hey guys,
With All this Warranty talk, the people who unlocked your bootloader. Do you regret it? Was the warranty worth sacrificing for custom roms? I want to unlock it but at the same time I keep getting these paranoid thoughts that I'm gonna need the warranty later on. WTF. Any help?
You can install custom roms without unlock bootloader. I have evil nxsense rom installed in my N1 without unlock my bootloader.

HTC honors the warranty even with the bootloader unlocked; I can't say that I've needed to make a claim myself, but that's the consensus from majority of members on this board. So, my advice is just go for it.
I had the same doubts as you, but you won't regret it

Agree with this. Although I've never had to make a claim either.
I unlocked mine as soon as I pulled it from the box back in January 2010. I have had no regrets about it at all. I have never needed warranty service, though I wouldn't hesitate to call HTC for a hardware related issue. If something went horribly wrong with a ROM flash or a radio upgrade, that would be my own fault and I would look into buying a new phone. But I wouldn't try to BS HTC to make them pay for my screw-up.

I have made two claims with my unlocked bootloader. Each has been hassle free and quick. Oh, and cost me nothing.
First, a few months ago for dust under the screen, repaired and sent back in 4 days.
Second, which was last week for power button issues. They received, repaired, and shipped back in one day. I got it back the next.
HTC is quietly brilliant.
thanks guys! i may actually unlock the baseband than.
is unlocking the baseband more beneficial than just doing a root without unlocking?
btw, so you guys think its better to safer to send it in and get it repaired if you have a unlocked baseband than the riskier "swap" (when they send u a new one and you send your old one in) method?

hey, did they send it back to you with a locked bootloader?
First time they relocked it.
Second time, they left it unlocked.
ROOT is fine

I don't see any point in unlocking boot loader while you can root the phone and do whatever you want. the only thing you can't directly do is to flash a partition usion bootloader commands but you still can do it if you use "flash_img" command in ClockworkMod Recovery (on the adb shell). I install different roms and I am on CM7 now.
I unlocked mine without wanting to. I flashed modaco rom and it just unlocked my boot loader. but there is supposed to be a way of locking it again. it's somewhere on xda...

Yeah, I like posters that don't know what they post.
1) No ROM can unlock the bootloader. User has to do it and the system has to ask for permission.
2) Once unlocked, it can't be locked, only by HTC.
To the OP: I've unlocked my bootloader long before "non-unlocking" way has been found. Never cared for it since, didn't need the warranty, and it's going to expire soon anyway.
Yes mine unlocked, and I have no reason to regret it, as my phone is a freak that can be locked again.
Worth doing in my opinion, and even if I couldn't lock it again, I still wouldn't regret it.

Mine is locked, but there are 2 goods reasons to unlock the bootloader:
1. Once the bootloader is unlocked, you always have a rooted phone. The next ota won't relock it.
2. You have more options to fix a potentially bricked phone.
I'm thinking about doing it for these reasons, plus it seems like HTC still honour the warranty.

I unlocked my bootloader because the warranty was gone anyway. Put the nexus into the washing mashine . Somehow it survived (Bluetooth, radio and camera gone). It actually was pretty tough. after about 10minutes in the mashine (60°C) the screen was still having fun inside the mashine.

1. Well, if you wanna update ota, you don't have reason to root your phone in the first place.
2. what more options exactly you have? simple, do not mess with HBOOT and Recovery partitions, and ur safe.
My opinion, use oneclickroot and don't risk it, cause HTC support behave deferentially now!

Nope, you're pretty screwed. When unlocking the bootloader, the phone tells you that your warranty is now void.
The nexus S has a oem bootloader unlock. In other words, samsung will not hold the fact that bootloader is unlocked against you. You do need to get rid of miui and get back to stock. There is a thread showing how to do this and provides the files you need. I'll see if I can find it for you.

I said that because I was screwed over by Samsung.
I just use cwm to flash the latest ota rom then locked the bootloader and reboot.
no issues from samsung regarding voided warranty. Perhaps you had sent it in with the bootloader unlocked?
Just use rom managers stock 2.3.3 and flash it... then lock bootloader by the instructions provided a post up
Just a heads up... same thing happened to a guy and he sent it in.for a speaker that wasn't working ... he waited over a month to get his phone back rather then them sending him a new one or refurbished

my friend said that the OTA updates require locked bootloader, then I would like to lock it again ...

Your friend is wrong. You don't need locked bootloader to get OTA.
To get OTA update, you need stock rom and stock recovery, locked or unlocked doesn't matter.
You can also flash the factory stock image without wiping your data (see link in my signature).
If you have root you can use this app to lock and unlock your bootloader: https://play.google.com/store/apps/details?id=net.segv11.bootunlocker

I guess something is up with your phone physical memory, but it doesn't matter, it really should not affect your warrenty (but the custom rom and recoveries will). Makes zero different to OTA updates either.

Honestly, I don't think they care if you have root either, but that's base on other user feedbacks. It seems LG warrenty is picky about other things and not very good from the feedbacks from what I read actually, but I haven't had first hand experience. But people have sent in rooted devices for repair.
I think just have factory image and stock recovery and stock kernel.
Solution !

Factory image 5.0 is out.

On the official google page. I'm a newbie and can't do outside links.

Only WiFi out so far it seems..
Am I blind, or did the Google Now launcher disappear? (I set up as new device, as I have both WiFi and LTE, and couldn't see which were which) I thought you just start Google Now and choose to use as launcher (so I can swipe from left to access Now) Someone please remind me?
Otherwise seem smooth (based on all of 5 mins usage. Used latest preview before)
Bah! I had to install Google Now Launcher...

Booting it now, glad someone said something, was wondering what was taking so long.
Mine has taken at least 20 minutes at the initial boot (spinning colors) screen. Anyone else taking very long?
Help!
On wugfresh when i enter the md5, it says mismatch, how do i fix this? Can you post the hash here? I tried the one for razor several times but to no avail.

I'm running Scott's build and it has root so yeah it's doable, just don't know how to do it on the factory image.
Root
Is there a stable way to root the official factory image of lolipop? Can I just flash something in recovery like the past? I am not sure what the word is on rooting now that the official images are out.

No and yes. You need it unlocked to install the image and they recommend locking it when done but you're not going to want to. It returns it to stock Lollipop so no root.
SuperSU 2.19 beta is working fine for me.

Post MHC19l update camera does not work at all

So i recently updated to the new mhc19l version on my nexus 6p (this is not android N, just the latest android update for the 6p). I did it via the flashfire method following this youtube video: https://www.youtube.com/watch?v=cvs0JQswTWw&feature=youtu.be
I dont have multirom so i didnt do the stuff it mentioned about that. At first I thought I was successful and everything was working great. I reflashed xposed to the latest version, and updated my elemental X kernal too.
But now when I do anything with the camera the phone gets really weird. Post reboot the camera preview will work only once. If I take a photo it crashes. And every time I try to do anything with the camera involved the thing will crash and not even load preview anymore. That includes 3rd party apps like snap chat. Also I can't edit quick setting tiles in system ui as it tells me system ui tuner has crashed, but that i can live with. The camera issues I can not live with.
None of that happens with my rooted 6p on the same build. I think you need to look at xposed, the kernel changes and all the other jiggerypokery you've done. I'd do begin by reflashing the factory image and do this manually either using Heisenberg's extremely clear guide, or by the flash-all.bat command that google supplies in the factory build. Then you can check camera, flash recovery (again, using Heisenberg's guide, it takes but a couple of commands), then root, add xposed, kernels and all that special sauce. Do it step by step, then you'll know when something goes wrong and only have to fix that.
Thank you for your help. I'll check that out. Do you think it may be because I updated from a pretty old build? (808L) I skipped a few updates and went right to the latest one, could that cause any problems?
Not really. I think it's because you've done too much using a tool and without checking things after each step. Stop using tools like flashfire when you don't understand what they do and get yourself up to speed with using the commands. After that, you'll spot where things have gone wrong and be able to fix or troubleshoot it within the community. No one can help you when it's an issue that could caused by one or more of a hundred things you've tinkered with.
It's not hard and worth the little bit of busy work and brain thought. You'll enjoy it!
Yea I like to tinker and stuff. It's just the customizations with dashclock and stuff that I don't want to lose. But I did app backups so hopefully I won't.
Something probably went wrong during the flash process. I highly doubt xposed or kernel modifications are to blame. I keep 12 xposed modules running at all times with kylo kernel which I have heavily modified with EX kernel app. Read Heisenberg's guide and learn to flash images properly and you should be good to go.
Before I do any reflashing today can anyone do me a favour and upload their camera APK?
Im just hoping it has something to do with that. Last ditch effort.
And thanks for the help guys
So i gotta ask. Using flashire only is it possible to lock the bootloader and flash small incremental updates without a problem? Its a bit sad to have a unlocked bootloader...

Locking the bootloader is nothing but trouble. You know what's sadder than having an unlocked bootloader? Having a bricked phone because an OTA failed and your bootloader is locked. If that happens there's no way to save it.

What method did you use to update? Did you use an OTA zip? Or factory images? I'd Is there a reason you used Flashfire instead of updating the proper way?

Hello you seem very knowledgeable on the subject. I just picked up a 6P and was wondering how does encryption affect things such as TWRP and root. Do you advise to disable encryption on the device for ease-of-use in TWRP and root.

Deception isn't necessary anymore, as long as you use the latest TWRP you should have no problems.

No, because if the OTA fails you won't have access to the option in Developer Options to enable OEM unlocking. Trust me, you want to have that bootloader unlocked. You don't wanna end up like the other guys who had to send their phone back for repair because they locked it.
