Would it be possible to install OTA updates if I choose to root the phone?
From what I've read, this is definitely impossible if I flash custom recovery.
But what if I leave stock recovery? Do I just need to reroot after the OTA, or is there another method to update?
Thanks
On my Galaxy Nexus, I get around that by just booting Clockwork Recovery (fastboot boot recovery.img instead of fastboot flash recovery recovery.img). Then I flash the OTA, re-flash su and I'm good.
If you are rooted with no custom recovery, your phone will still accept the OTA. When you install the OTA, you lose root. You can use something like OTA Rootkeeper to keep root, or reroot after the fact.
I am new to nexus devices... how often do they release OTA updates?

If you have a custom recovery like "ClockworkMod, Twrp etc" then you can't get OTA's.. some say if you have Superuser you can't get OTA's either..
You would need to install a stock recovery and download the OTA file and flash it..
OTA updates don't happen that often.. when the phone first release you might see a couple to address certain issues.. or if the AOSP code changes you'll see a update..

On the Galaxy Nexus, you can update via OTA while rooted. Everything else must be stock. The update will usually break your root, but it's pretty simple enough to re-root on Nexi.

They send out OTAs whenever they update Android versions. For the GNex, I think I got 4 version updates since I bought it last June (4.0.4 -> 4.1 -> 4.1.1 -> 4.1.2 -> 4.2)

any way you can flash the OTA update with clockwork?
I used Google's batch file on windows to flash the stock 5.0, having unlocked the bootloader and also installed the chainfire root. Just wondering whether I'll get any fixes, or whether i'll have to always repeat this process, wiping out everything on the device in the process.
You may get prompted to download and install new updates when they arrive, but they will fail upon installation unless you're 100% stock.
there will be an OTA update notification if you have stock rom wether you have a sotck or a custom recovery. But if you download and install the OTA update having a custom recovery, the installation will fail and will show an installation or update error. You will be stucked in "no command" image. so better restore your stock recovery as well before downloading any OTA updates..

Does the Google image download page (https://developers.google.com/android/nexus/images) get updated as Lollipop gets updated? Or am I going to have to do OTA updates?
hmm.. im not sure which comes first.. but, if you want to get OTA, you'll have to wait for your device to get its turn for the notification to appear. The effect will still be the same though if you flash that google image to your device.. And flashing that device, will save you time from waiting for your OTA to appear on your device.
Cheers! :good:

Well, I'm a bit confused. I'm on stock, but i need root, so i installed cfar, which I think included super su. when a new version of super su came out (i was alerted via google play), i needed to install the twrp recovery (which I didn't have installed at that point) to update it. So I guess I'm not stock any more, even though I've not actually put a non-stock image on. So even if the OTA update message popped up, I doubt it's safe to install it that way, even if it let me. I'm just not sure whether I need to a factory reset/wipe etc before updating, or if I can do a dirty update (the OTA is effectively a dirty update, isn't it?). And, like i said, i'm not sure whether that page gets updated with new images, or whether you're supposed to just put the initial one down and then do OTA updates (and only then root, change the recovery etc).
You have a stock rom but with a CUSTOM recovery. Yes, ota will prompt you to update, but DON'T. You should convert to stock recovery first. Because if you do, the update will push through, but once it asks you to boot to make the update in effect, you will have a NO COMMAND error - bootloop, and only fastboot and recovery (sort of dysfunctional). Just like most of the people here, including me. So make backup of your files first before doing the update. Cheers :good:

If having a custom recovery is an issue, why could I flash ota zips from custom recoveries ever since buying the tablet?

Hi, what i did was flashing the official factory image from google via fastboot/bootloader... Make a nandroid backup first though.. Because you'll need to clean flash (system partition/cache and data) to avoid future problems.
please educate me
A few weeks ago I rooted my N4 with CFAR (& of course had to wipe out everything). My understanding was that now that my bootloader is unlocked, I can sideload new images, thus sparing me a rewipe -- & in my ignorance, was anticipating that ChainFire would make 5.0.1 images in due course.
So, If I want to root subsequent 5.x.x releases, how would this work in real life??
Can i just restore stock recovery and then install the 5.0.1 ota update without losing everything?
Hi! I have my phone rooted and it has TWRP installed. Recently, I received the 5.1.1 OTA update, but when I hit the install button, it boots to the recovery and does nothing. How do I install the update using my current recovery?
Thanks!

Flash the stock images directly, or flash your phone back to stock/unroot and download the OTA from your phone and it will install.
If you have a custom recovery, the OTA will always fail verification checks I think now on 5.+.

But if I flash the stock image, I'll have to reinstall the apps, and such. Right?

Yes, unless you back them up. Otherwise, you will have to redownload and install. You will also lose anything you have stored locally unless you remove the -w from the flashall.bat script (which will prevent the wipe of the partitions).
just download the image from google and extract the system and boot images and flash them in fastboot
Hello,
after I've unlocked the bootloader can I still get OTA updates?
I'll just be on stock ROM with root. I also make a backup with nothing on except TWRP.
Lets hope so

Yes you'll be able to get new updates with unlock bootloader.

Can you elaborate on this? The last I heard unlocking the bootloader (using the official procedure) stops OTA. Has this changed ?

I never said Official getting OTA's , but i believe this is going to change staring with the new Unlock Bootloader procedure.

OK, but AFAIK even with the unofficial unlock (with TWRP and root) the OTA will fail - unless you unroot and go back to locked stock bootloader. Correct me if I am wrong.

In my experience, what makes the difference - so far - is the recovery. Official ZTE updates and ROMS only flash through the stock recovery.
Unlocked bootloader has made no difference to me.

If you try to flash Official OTA yes will fail, cuz isn't modded to skip partitions check.

This is getting confusing. "Getting OTA updates" (as OP asks) usually means that the update installs "on its own" by tapping notification rather than flashing via recovery, which is a bit more complicated process.
So back to the OP question: With root and TWRP can one get over-the-air official updates from ZTE without going to the recovery manually? I believe the answer to that is NO.
That said, there is probably a work around in getting the update, probably by manually flashing partitions that have changed in the update.
Is this right?

Well OPs Question actually was if OTA Updates are possible with unlocked boot-loader...
Root and TWRP is a whole different scenario and won't work with OTA for sure as OTA needs stock recovery and will check for unmodified system (not rooted)...
But if you are on stock with unlocked bootloader you should get notified about OTAs (as until now it did not check for bootloader lock status, but that could change in future) although I don't know if it will install correctly

OP mentioned that he used TWRP to make a backup, I assumed he has replaced stock recovery with TWRP, but that may not necessarily be the case.
If your device has an bootloader that was unlocked "unofficially" (either via sideloading the official unlock method or DrakenFX & Unjustifieddev's method), but is still completely stock (stock System, stock Boot, stock Recovery, stock everything besides the unlocked bootloader), you can still receive and apply OTAs. However, if you changed any of the partitions, like boot.img (root), recovery.img (TWRP), system.img (changes to system), you will still receive the OTA, but you won't be able to apply it, the update will fail. If you went through the official bootloader unlocking process, which involved you submitting a form to ZTE with your device's IMEI, you would no longer be able to receive OTAs.
What I did was sideload the official B20_Boot on by B20 device, unlocked my bootloader, flashed TWRP, flashed the TWRP Stock B20 dumps that were posted here on XDA, and reflashed stock recovery. This made my device completely stock B20 besides the unlocked bootloader. I then applied the official B27 OTA update, and it installed fine. I then reflashed TWRP (since my bootloader was still unlocked) and re-rooted my device.
If a new update comes out, I can just reflash the stock B27 TWRP dump posted here on XDA, reflash stock recovery, (if needed, reflash stock fastboot), and apply OTA.

So, with this procedure, do you lose all the app installations/other customizations? I believe that all of the application data is on a non-system partition (/data?) but did you need to go through all of the setting up of the phone after you did the upgrade this way?

Yes. Unlocking the bootloader does a factory reset, and doing a TWRP restore of a stock image (which overwrites your current partitions) overwrites what you had before.
EDIT: Actually, I think Internal Storage gets erased as well, but your microSD card will be fine.

Hmm, had guessed as much. I knew the bootloader unlocking did a wipe, but was hoping that recovery-flashing would do a backup/restore, as if the update had been applied through the in-ROM update procedure. Unless the OTA process only gets deltas and flashes them, leaving fs intact.

Yeah, the OTA doesn't straight-up replace partitions, it checks and patches the existing partitions, so if a partition has been changed, the OTA install will fail.
Hi all,
Was wondering if a rooted OP5 can receive OTA updates as a non rooted one.
Thanks in advance!
Also, will rooting wipe/reset the device ?

1. Yes you will receive the OTA but you will loose root so after the flash you have to reroot
2. Rooting does not wipe the device, unlocking the bootloader however will.
Read this thread first https://forum.xda-developers.com/oneplus-5/how-to/oneplus-5-unlock-bootloader-flash-twrp-t3624877.
In addition a rooted device will not receive incremental updates. It will alsways have to install a full package (as far as i know).

Yes you can download it but it will not install if the system is modified. You can flash it with twrp and reroot afterwards.
How could you download an incremental update? My system updates section did not even offer me a download of the incremental version.. and where else could i download it?
