Yes
1) uninstall magisk
2) flash factory image (with or without wipe)
3) lock bootloader (this will wipe the phone)

Personnaly (and tested) I would prefer the OTA sideload method before relocking bootloader, this may avoid bootloop or start screen stuck.

Can you give specific instructions? Does rooting cause a loss of battery life?

Specific instructions may be found on Google developer site, quite easy.
Regarding the battery loss, no, it won't interfere. More, I have a custom kernel (EX) which preserve it significantly.

Just a personal preference maybe but... I would say flashing the full factory image WITH wipe still enabled is your safest route. Also DO NOT toggle off the "OEM Unlocking" switch until you are super sure all is back to the should and booting properly! There is actually no reason to ever toggle that switch back off in my opinion.

If the relocking process wipes the phone (I've never done it myself), then there is zero benefit to flashing the factory image without having it do a full factory image. You need to backup your data in either case (if you have anything you want to keep). Having the phone do a full factory reset is the best way to ensure everything is back to normal prior to relocking the phone.

Perfect follow-up to my post. You did a better job articulating the risk avoidance aspect. Lol

Better yet... Flash full October image and then take Nov ota before locking.

Sorry for the late reply to this thread, but I just went through this with my Pixel 4XL. I did a complete uninstall of Magisk and rebooted. I then went to the Google Pixel image page and used the flash feature for the latest version. I selected the option to wipe, restore partitions and lock the bootloader. It all seemed to go well until I booted the phone and ran through the setup pages and it prompted me to re-download my T-Mobile eSIM. I went into settings and deleted the eSIM and then did another factory reset on the phone just to be sure.

I have a question what happened to my eSIM if I unroot and flash the stock images? Can I use same eSIM QR Code or I have to get new QR code from my carrier. I'm using it on Middle East.

[Q] About Security in Recovery

Hello!
I have a question, I tried too much ROMs, and now I decide to keep my Stock ROM with a Custom Kernel, like:
Stock ROM: http://forum.xda-developers.com/moto-x/development/rom-firmware-stock-brasil-4-4-4-zip-t2873516
Kernel: http://forum.xda-developers.com/moto-x/development/kernel-zwliew-kernel-r1-t2926315
And for security things, I have bought a Kaspersky Licence to track, block and wipe data, with SMS or WEB commands. But if I got stoled, and the thief knows how to get in the Recovery Mode, he will wipe the ROM and get access to my data in the same way, without the Kaspersky tool.
So I have a question, is there any way to block the bootloader and block the recovery?
I don't have the answers but I can probably give you some good questions to ask.
I don't imagine there's any way to "block the bootloader" if that's what you really meant to type.
First thing you might want to do is flash the stock recovery. You won't be able to flash custom things with it but you can't do much else in stock recovery like you can in a custom one.
If you did want to make changes which required a custom recovery you could already just flash one. Granted, a tech savvy thief could always do the same if they realized that you're unlocked but that would probably weed out the average opportunistic pretty thief.
### There may be risks to this that I don't know but if you wanted to take it a step further I WOULD THINK you could even relock the bootloader. I unlocked via the China middleman so I have my unlock code to use/reuse whenever I want. I think I recall hearing that sunshine will also relock and reunlock the same phone once purchased for that phone? What I don't know is if there's any risk to locking a bootloader with a non stock system.

No.
There is no security with an unlocked boot!
One reason THEM don't want it.
See the Philz dev thread (search) for a discussion on this issue.
If you are concerned about security, then flashing a custom ROM/Kernel is the wrong thing to do. You should leave the phone stock, enable device encryption, and also have stock recovery and a locked bootloader.

No. Because recovery is always accessible.
You can lock your phone at any point, but that isn't going to make it any more secure if you are rooted and/or have a custom recovery installed.

Hello! Another question!
If a thieft with experience in ROMs/Root and this things get a Normal Moto X Unrooted and Original and Stock. Its is possible he wipe the data, of course...but Its possible to him, get the phone rooted and wipe the data too.
I'm trying to say, a phone with root and unrooted is the same thing about security, because if the Thief have experience, he will do the same thing...a unrooted phone wipe will lost all the datas, a rooted wipe will keep photos and files, right?
Factory reset doesn't care if you're rooted or not. If the phone is locked, unlocking will wipe data. Rooted or not, a factory reset deletes everything. Stock recovery will wipe the emulated SD card as well, where custom recovery doesn't by default, though it still can if you want.
Being rooted makes it easier to pull the data off the phone, but just because one isn't rooted doesn't mean your data is safe.

ATT nexus 6 questions

Couldn't find much about this varient just wanted to ask a few questions.
1. Do I treat it like every other google play nexus? Unlock boot loader, flash twrp, boot, backup, reboot, wipe, install ROM? No different partition weirdness?
2. Cm12, are the hotspot checks removed? Fiance is limited data plan I'm not so while out she normally uses my data via hotspot.
3. Cm12 have notification light activated and customizable?
Don't really care about the Sim lock honestly. Been with ATT forever and poor so not leaving the country anytime soon.
Thanks, sorry for repeat questions just didn't get solid answers from things I found.
No partition weirdness. Root as normal. It does have its own boot logo-thing though, which is lame.
Unfortunately I don't know about CM12. Sorry

At least you answered my bricking level question! Thanks!
CM 12 does have working hot spot on AT&T and customizable notification light. And, boot logo is easily removed after root.
Somehow I soft bricked my n6. I unlocked boot loader, installed twrp, went to backup and it couldn't find any partitions. Tried the flash all script from google factory image and that failed as well. Had to flash boot radio recovery etc images each manually to get back to a booting phone. Then installed twrp again and backup and flashing worked.
It was an adventure but I'm good now. Weird not sure why it did that. Must have been an encryption issue.
On the stock ROM you have to tick a box in developer options to enable OEM unlock. I forgot to mention that earlier. That may have been the issue.

[Q] can't update to 5.1

Hey guys. Forgive me for my noobness here, I'm still kind of new to rooting etc. So I've got an Australian nexus 6, running 5.0.1, its rooted, I used the nexus root toolkit, and it installed twrp, I want to update to 5.1, downloaded the update from aosp or whatever and tried to sideload it, I kept getting errors and fails. Both twrp and adb are updated. Now I think from what I've read, after rooting a 5.0 device you can't receive OTAs anymore. I just got the OTA notification, I downloaded it and pressed install, it restarted then booted into twrp and didn't start the update process. I've tried unrooting but it failed. My questions are: can I install the OTA through twrp? Is there a way to bypass twrp to continue the update? Can I factory reset through settings on the phone to go back to stock and then do the update that way? (I've heard its bad to factory reset like that, not sure why or if its true?) Just want 5.1 already! Any help is appreciated, and if possible dumb it down a bit because some terminology still is not known to me
Thanks in advance

If you're unlocked, rooted and have TWRP, why not just install custom ROM? Otherwise you can download factory image that you want, unzip and flash images individually via fastboot. Just don't flash user data and you won't loose data.
Just use the toolkit to 100% flash back go stock. It will unroot and reinstall stock recovery. Just remember to always keep USB debugging on and keep that boot loader unlocked. Once your back to the out box state you should be v able to receive ota. Or just use toolkit to flash the new stock image for your device. Ends with I.

I don`t erase and flash userdata usualy, its good to erase cache and then flash cache cache.img. A data factory reset after the procedure is adviced however for preventing fc`s and such.
So in the end is should wipe anyway? Oh well I was trying to avoid that only as a last resort. It wouldn't even let me unroot through the toolkit for some reason...
I, too, would like to know this. I have looked through many forums and sites to try to find an answer.
My Nexus 6 is:
- bootloader unlocked
- TWRP recovery
- rooted
I would like to update to the latest 5.1 without wiping my device. I don't want to lose my setup and accounts.
Is there a flashable update.zip that allows the update to 5.1? (I have seen a few, but they usually have encryption disabled - which I believe will cause me to lose my data?)
Would it be easy enough to restore stock recovery and unroot, which would allow me to flash the OTA normally - then just flash TWRP and root again?
How would I go about this?

Why not just download the factory image of your choice, then fastboot flash everything but user data. You will keep all your data. Many users go this route. Personally, I like a fresh start that doing a factory reset gives. I backup everything to the cloud and then restore what I need to have on my phone. I mention this because it is recommended to preform a factory reset after installing the images separately. Thus avoiding any boot loops or force closings.

So do I need to flash all the images?
Can I also leave out the recovery image - or do I flash it and re-flash TWRP after?
Does flashing the OTA (normally) factory reset the device wiping all accounts and setup?
I don't want to perform a factory reset as I use the device for business and have many email accounts, sync accounts, contact accounts and other tweaks that I don't want to have to spend a few days setting up again.

I understand, everyone's situation is different. No, an OTA will preserve all your accounts and data. Your best bet in your situation may be to flash stock recovery and remove root. Then you could sideload the OTA. Also, though I don't use or really recommend the use of toolkits, the NRT may have options available for your needs as well. There is a possibility that just removing root and TWRP may still leave traces behind. Enough that the OTA may fail.

Relocking the bootloader wipes the device, so you don't want to do that.
What is your ultimate goal? Your absolute ideal situation, once you're updated. Let's learn that and work from there.

You don't have to relock your bootloader. That doesn't matter. As for recovery, I believe all you have to do is obtain the proper recovery for the build you are currently running, the fastboot flash it from bootloader.

Thanks @Evolution_Freak I'll give a shot at flashing just the stock recovery, unrooting and trying the OTA

Is there a root method that doesn't require unlocking the bootloader? (LRX22C)

I just got my N6 a few days ago, and JUST got everything all set up how I like. I went to go root it, and the method mentioned in the "All-In-One" stickied thread requires you to unlock the bootloader, which says it will factory reset the device.
I don't want to factory reset at this point, I just want to root it. I've never had to wipe a phone or unlock a bootloader to root a phone before, so this is new to me.

There is a way, I believe, by running TWRP on your PC and flashing SuperSU from your PC. However, it's not a recommended method as you will have no way of backing up. Also, if you get caught in a bootloop, you won't be able to recover without a custom recovery.

and you don't have to "hack" a nexus as well, as google provided an easy way to unlock your bootloader and to obtain root. if you just got your nexus a few days ago, just unlock the bootloader and root it. loosing a few days of information is more than worth it for root. don't waste your time worrying over a few days of data.
Can be done but not recommended.
adb backup/restore can save a little bit of information for you, but I wouldn't go in expecting it to save everything

What did you set up? You can back up your messages, and your apps will re-download. Your photos are already syncing to Google. If it's not rooted, I can't imagine you've done that much customization.
Lesson learned: unlock should ALWAYS be the very first step you do on a new phone.

the only thing i havnet worked out how to do is take the king userr off. once your finished rooting, in order to sustain root that app becomes a permanent addittion to the phone. ive deleted it before and lost root. but just reinstall and follow the steps again and you gain root again

Yes we're aware but we do recommend against these one-click methods usually. Rooted users cannot accept OTA updates, so the only way to update is with an unlocked bootloader unless you're going to have a custom recovery (also highly recommended) so you can flash flashable zips.
Also you MUST go into settings and enable the "Allow OEM unlock" in developer options, because If you break your OS with root, which is easily done - you're going to become stuck as you can't unlock the bootloader. Not too bad if you have TWRP recovery installed, but then that becomes a single point of failure.

Good stuff. Once rooted, Flashify is a great tool to flash TWRP. With the nexus 5, you could unlock the bootloader with an app that didnt wipe everything, which was great, but Nexus 6 doesn't allow that, but always do go to settings > developer options > OEM Unlock (Set to enable). Without this set, you cannot unlock the bootloader from fastboot. Also, side note, developer options doesn't show up until you go into Settings > About phone then tap "Build number" several times to make the option visible. Think its 7 times.
It's interesting saying that you need kingroot to remain on the device. Thats a bit of a pain. Does it install SuperSU or not? If not, might be interesting to see what happens if you install the SuperSU app from Play - whether it allows it to be removed then.
My preferred method however is definitely unlock the BL, fastboot flash TWRP, From TWRP flash SuperSU zip (or rooted ROM).
For the record, I did end up factory resetting to do it the right way.
Is this easy to unroot if a new OTA update comes out?

Yes and no. To "unroot" you have to fastboot flash system.img and boot.img, which if the factory image is available for the version your OTA will raise you to, you're done. If there is no factory image for that new version, you must flash the system and boot(and recovery) of the expected version, then OTA. Note, recovery version isn't checked. Only system and boot. Just that recovery must be stock for OTA to flash.
To be honest, easiest way is to wait for a rooted flashable zip to be made available and flash via recovery

Greetings,
Please refrain from bumping a thread until at least 24 hours have passed. XDA Assist is a very busy forum and the Assist RC's have lives outside of XDA as well.

look up how to flash a factory image.. because as i see it, you only have two choices, flashing a factory image, or getting an exchange from wherever you bought your n6.
Did you ever let it finish optimizing apps? Any time an OTA is installed the first boot takes what seems like forever aka 10+ mins depending on number of apps installed. If you interrupt the process I guess it's possible to corrupt something.
Otherwise like @simms22 said install the factory image to reset it entirely or take it back to in for repairs.
If you'd like to run the factory image install yourself follow Google's instructions and download 6.0.1 image for shamu (Nexus 6) at https://developers.google.com/android/nexus/images.
And also I did not enable developer settings nor did I root my device (it is completely stock) so my bootloader is locked and USB debugging is not enabled
Guys these are my options
1) sideload an ota through root toolkit
2)
Wipe data and reset using nexu
S root toolkit
Thing is, my bootloader is locked and USB debugging is disabled.
Go ahead and enable usb debugging and unlock the bootloader.
Once you have everything updated and you don't plan to root or want to do manual installs or take back ups just relock the bootloader when you're done and turn off usb debugging.

I think you missed the point... The device is bootlooping = impossible to enable USB debugging and unlock the bootloader.

I think you need to go with option 3 - get a new phone under warranty, which shouldn't be a problem.
With your new phone, before doing anything else, unlock your bootloader. That will save you a lot of headache.
Edit: Did you try doing a factory reset in recovery? Check this link for instructions: http://www.digitaltrends.com/mobile/use-recovery-mode-android/
The Final Answer
If you aren't going to replace the phone under warranty, then this is your only option.
1. Download Nexus Toolkit. http://www.wugfresh.com/nrt/
2. Use the toolkit to download the latest factory image.
3. Boot into Bootloader
4. Flash factory image

But hey, what do I know...?
As it happens, I'm a big fan of NRT, having praised, recommended and contributed to it a number of times, but I don't rely on it solely. And I would not go so far as to say "My way is the right way".
Just saying...
Its not a boot loop if you were able to get to the "optimizing apps" message. and the fact that it got to the "optimizing apps" message means your system partition is functioning properly.
Ive had optimization run for 35+ minutes before booting when i took my first official update. You may have messed the phone up if you forced Reboot/power off while it was optimizing.
try and let it boot, if you get the optimizing message then plug it up and let it sit overnight if you have to, i promise IT WILL BOOT.
worse comes to worse, just google "nexus 6 back to stock". your boot loader doesnt have to be unlocked, and usb debugging does not have to be enabled to return to stock

Seems I solved the problem myself. I used the rootkit- I basically just unlocked the bootloader and then reset it and flashed marshamallow 6.0.1 and I'm gonna relock the bootloader tomorrow. It was easy enough even for a noob like me.
I wonder how you did it. I can't imagine that such toolkit is able to unlock a bootloader when "OEM unlocking" wasn't enabled in your rom. Or did you enable that before?
