Hi,
I'm using HD01BA (= EU version) with unlocked bootloader and root with Magisk. I understand that updating OOS or updating Magisk is quite annonying as there's no TWRP and as it needs specific precautions such as disabling Magisk modules and reinstalling them after updating.
Since I now barely use root, I think I would benefit more from being able to get OTA updates than having root. I'd like to know how to unroot - and relock bootloader if necessary - without bricking the phone.
Would I have to wipe everything ? Will unrooting enable OTA updates or do I need to relock bootloader as well ?
Thanks

It will erase everything and lock the bootloader, yes.
Is there a way to only unroot (flashing a clean boot maybe?) in order to get OTA updates? Even if the bootloader remains unlocked

Yes you can unroot by flashing stock boot.img, but why?
You get new updates when they are available through system updates in your settings/updater app regardless of the bootloader/root conditions.
The additional steps that has to happen after the OOS update is to keep Magisk/root.

I don't think I do, I'm still on 10.0.9 and there's no update showing up, even in the settings. I remember reading somewhere that on this phone, unlocking bootloader or rooting (I forgot which one) disables updates notifications.
What bothers me is that i) if I want to update OOS I need to delete all Magisk modules then reinstall them to avoid bootloop and ii) if I want to update Magisk, I'd have to do all the steps again including flashing a patched boot, right ?
In addition, Magisk may no longer be able to hide bootloader unlocking from apps with Android 11.

You can use Oxygen Updater https://play.google.com/store/apps/details?id=com.arjanvlek.oxygenupdater
And the bootloader unlock check is Google's doing with hardware key attestation. This may not get cracked.

Reverted back to "Locked" bootloader, but still get error when updating to 5.1.1 OTA
I just used Nexus Root Toolkit 2.0.5 to revert back to an OEM "Locked" state which I ahd confirmed by rebooting into bootloader. The reason I did this was so I would be able to update my device with OTA updates, but I keep getting an error every time I try to update to 5.1.1.
What are my options?
Unlock, flash Nexus Factory Images.
From what I've read if you get a failed OTA install it won't let you un-root, re-lock, etc... and take the OTA. This is to protect your device.
ETA: Do you even have to have the BL flag locked to take an OTA? I don't think so...

NEVER NEVER NEVER NEVER NEVER LOCK YOUR BOOTLOADER!!!!
1) This does not in ANY WAY impact OTAs.
2) This has the potential to *LOCK YOU OUT*.
Get your updates here:
https://developers.google.com/android/nexus/images
So then how can I go back to being able to update via OTA?

If you want to get OTA's, fastboot flash the stock system.img and boot.img > https://developers.google.com/android/nexus/images
But if you're going to do that, why not just fastboot flash the 5.1.1 factory images?
As posted above, do not relock your bootloader. It does not impact your ability to accept OTA's and can end up bricking your device.

Is there an idiot's proof guide to this?
And besides helping me unlock my device once again as you guys recommend, can the Nexus Root Toolkit make my life easier by flashing the the stock system.img and boot.img so that I can get OTA's?

Here's a guide. Note: use the "Long method" > http://forum.xda-developers.com/nexus-9/general/guide-how-to-unlock-bootloader-flash-t3035153
Toolkits are OK if you understand how to fix a problem when you run into trouble. I'd suggest that you use the manual method, but it's your decision. There's a thread in the Development section for NRT if you choose to go that way.
Basically the title. Is there a difference?
Also, I have a RN3P-Kate. I'm seeing there are a few methods to root and install TWRP. Which is the easiest/safest/best way?
No, it's not the same thing.
They are all pretty much the same, you need to have an unlocked bootloader (request from xiaomi), then you go to fastboot mode, install TWRP through fastboot, and then you can flash supersu to root.

Will I still receive OTA updates if I root, or will I have to manually update (via flashing) and reroot again?

I'm getting some conflicting information about this. According to some people on reddit, if I use Global Dev for example, I would need to unlock the bootloader to change from Global Stable to Dev, and then Dev would offer OTA (maintaining bootloader unlocked, i.e. staying rooted), or am I misunderstanding this?
Cleaning this up and clarifying as my original post was vague:
It is recommended that you unlock your bootloader before the 7.0 Nougat update. Although it will still be possible the process will be more difficult and risky afterwards.as you will need to use one of the edl mode tools (axon7backup, axom7tool).
The easiest way is to download this kit f you have the A2017U: (I can't speak to other models) (This kit and instructions are thanks to @jcadduono)
https://build.nethunter.com/misc/axon7/AXON7-A2017U-BL-UNLOCK-KIT.zip
https://build.nethunter.com/misc/axon7/INSTRUCTIONS.txt
The basic steps, which the above zip with take you through in detail are:
1. Flash Official B20 , enable OEM UNLOCKING after flashing.
2. Flash BLFastboot zip provided by ZTE when they had unlock method.
3. Enable OEM UNLOCKING in Developers Option
4. Boot to Bootloader
5. type : fastboot oem unlock
6. Done
Note: If you do not have the OEM UNLOCKING flag set in developer options you will get a soft brick. Also bear in mid this will wipe data.
All that being said I've heard Nougat to is going to be great from those in the know. In their words ”Well worth the wait! Hang in there!” from a HIGHLY credible source.
Why would anyone relock before update? I do agree anyone who wants to unlock should do it now.
lokissmile said:
For anyone looking to bootloader unlock, I've heard that the methods might change when the N update rolls out. It's a major update and although I personally don't have N and can't get a direct answer because those who know for sure are under NDA. I can tell you that the advice given to me is to not re-lock. So if you are thinking of unlocking your bootloader I'd do it soon while the methods are stable. Google confirmed that daydream is certified in an upcoming update so the daydream version of the stock ROM has been through googles QA. Might as well get ready now, we will probably have another surge of custom ROMS shortly after. I'm just sharing what I think is a best practice.

OK, so just to make it quick, for everyone, unlock your bootloader sooner than later. It is safe since you can revert it to a locked state at any time later.

No need to bootloader lock an Axon 7 to get SafetyNet (Android Pay, PoGo, etc). Just do it the XDA way. But never relock!!!!
Could one of you guys explain whats so dangerous about relocking bootloader since u seem to know something I don't.
I have unlocked and relocked my bootloader several times by fastboot oem lock and restoring my stock fbop partition.
Have I done something wrong?

Read the OP.
I think what the op is trying to say is that by unlocking the bootloader you won't get ota updates. You would need to wait until a twrp flashable update is out or a rom running Android 7.

That's how it's been since modifying the bootloader was a thing. Unlocked bootloader = no OTA.

@stevecaboose
Unlocking Bootloader = Yes to OTA's.
Modding System and Boot = NO OTA's
hope that clear things up.
Close enough lol!
To be clear, it would be best to unlock before N is pushed out. I have it on good authority that unlocking your bootloader after you update to N will be more difficult and risky. Relocking would put you in the same situation. It's trivial to return to stock system+boot with an unlocked bootloader and TWRP and then the OTA will come through just fine. Or you can just wait for the TWRP flashable N stock ROM.
So to be clear, since I'm not 100% sure what affects the "system" and "boot" areas: I can unlock my BL using only guide 2 in this link ( https://forum.xda-developers.com/axon-7/how-to/guide-install-twrp-unlock-bl-flash-t3517379 ) and still get OTAs? If I install TWRP does that make me OTA-ineligible?

TWRP/BL unlock doesn't affect OTA, ROOT does.

You're totally wrong there,
TWRP will affect OTA's if the OTA need to check/patch recovery, BUT been Bootloader Unlock will NOT effect OTA.
To manage a clean/successful OTA's installation, you need to be FULL STOCK. (System, boot, Recovery, aboot if the OTA need to patched).
I think the OP was trying to say that it's possible current tools will not work to unlock the bootloader after the 7.x ota is installed.

I'm not fully agreed with that. You can install OTA's when you receive it, download it, install it when first booted into twrp cache. Only if you're not rooted. When you're rooted first unroot and in principle this should work.
There are several cases on internet about that. Even I did it with an unrooted but TWRP-ed Zopo C2. Received an OTA and installed it.
Im always glad to learn but IMO there are some possibilities to do the ota after all. But I am willing to accept it's a general fact that twrp could affect the normal OTA.
Edit : let's wait and see when B10 is rolling out and if I get a notification about that and if I can install it as a normal OTA(not with SD) with TWRP. Keep you updated:cyclops:
Noob here, forgive me ...
So what is the best way to only unlock bootloader without flash twrp?

1- Download Official B20 from ZTE SITE (look Software Updates for the 6gb variant)
2- look in the forum for the B20fastboot zip file
3- Move both files to your SDCARD.
4- Enable OEM Unlocking under Developers Option
5- boot to stock recovery.
6- Install B20 official update via SDCARD (this will wipe Data)
7- boot and re-enable OEM Unlocking
8- boot to recovery and install B20fastboot zip
9- boot to Bootloader and Unlock bootloader using this command.
Code:
fastboot oem unlock
If I remember correctly will reboot and factory reset the device , you'll need to re-enable OEM UNLOCKING and boot to Bootloader to flash TWRP 3.0.3 USING fastboot commands
So, long story short, I recently bought a Nexus 9 from ebay which arrived with factory reset protection.
I have spoken to both Google and HTC about the situation and both were of no real help except for saying a few things outright between them to give me good enough reason to believe one of two things.
That 1 - it is possible to flash factory images over a device with a locked bootloader
or 2 - it is possible to unlock the bootloader without having access to developer settings
Anyone have any experience with either of these possibilities?
https://developers.google.com/android/ota
Full OTA Images can be flashed onto devices with locked boot loaders.
You need to boot into recovery and select sideload update.
Yeah, I know how to do that, but that only goes for updates, doesn't it? I tried to sideload a previous build onto the tablet but it failed the procedure, so it doesn't really solve the issue and if I flash a more recent update I still get FRP :/ If I wanted to revert back to the 7.0, or even marshmallow, would that be possible? Or does that require an unlocked bootloader?

Those are full ota images, same as factory image. Meaning full package.

Ah yes, now I see your predicament. Unfortunately, there is no "there" there. You do need an unlocked bootloader to wipe the system clean with a factory image, and as you noted, the Full OTA Image will recover you from a system that won't boot, but it won't get rid of FRP.

Never found out how they do this.... are you able to boot in to recovery? if you can do that you may be able to flash a recovery OTA through 'apply update from ADB'. Worth a shot

it's only a bad move if you make a mistake and can't repair it because your bootloader is now locked. But if it goes well then you're all set.
