I finally managed to find out where my phone downloaded the Sprint Nougat OTA file, and copied it to my SDcard.
My phone is a Sprint HTC 10. The bootloader is unlocked and my recovery is TWRP, but other than that I am stock and unrooted.
Everyone says you need to be on stock everything to install an OTA update (though I had no issues installing previous OTA updates directly, but all of those were small), so I was reading up on flashing stock recovery.... but several people commented that flashing a stock recovery on their phone wiped it. I really don't want to take that risk, and with TWRP I can make a backup of my entire phone. So I wanted to know, if flashing an OTA update fails from TWRP, could that brick my phone bad enough that I wouldn't be able to flash the TWRP backup to restore it? Or can I recover as long as I can boot into... well, recovery. Would the OTA update overwrite the recovery too? Especially if I try to install it from within that recovery?
I was told to extract the "update.zip" file from the OTA.... but there is none in there, is the OTA zip file itself what they meant by "update.zip"?
flashing an ota with twrp won't work...at least it won't update the firmware bits.

Maybe a noobish question, but im sorry
As the title says : if i root the phone, will i be able to recieve updates OTA ?
edit : and same question : if i get cwr (for nandroid backups) will i be able to recieve OTA updates?
Thanks guys
So long as you're running the stock rom, you should still get OTA updates. They may or may not break root, but you'll have to risk that. If you're running a custom ROM, then you probably will not get OTA updates, but you can of course update your ROM as per the developer builds.
You will remove root if you install an OTA, and I have heard of people actually bricking their phones installing an OTA with root.
installing CWM will break OTA even if you're on the stock ROM because it flashes in stock recovery, not CWM.
...and from the mixed responses you can tell that it wasn't really a noob question. (all answers were partially correct, btw).
The update will still get pushed to your phone, based on the build version of your phone. The custom recovery will fail to install, at which point you can simply install it yourself by performing a manual flash via recovery.
Depending on the extent of the update, you may or may not lose root, and possibly even your custom recovery. Your best option is to manually flash an update, then the su.zip, and I've also put together flashable a script to prevent your custom recovery from reverting to stock at your next boot (I'll post it when I get chance). Flash all the files while in CWM, and you're golden!
I have reached maximum thanks-per-day, otherwise i would give a thanks to all of you..
So, i still have few questions :
1) If i root, get custom CWM, but stock rom, will i still be able to SEE ota update, and to DL it over the OTA (not flash it)?
2) Can i brick my device with flashing ota , while rooted and with custom CWM ?
Thanks in advance
-yes it will still show up.
-it won't brick your device, but the update will fail, and you'll have to pull battery to gay back into the os.

Okay, so I installed Clockword Recovery and ROM Manager so that I could get Jellybean early. And it was awesome. But now I'm getting bugged about the OTA update, and I kinda want that. Ofcourse, Clockwork Mod Recovery won't let me install OTA, so how can I go back to stock recovery? Because I dislike the idea of not having OTA updates anymore...
Hopefully before you get hundreds of rude entitled responses you should check out some of the stickies on the various forums. I believe there is one with a title that matches exactly what you are looking for
If not having stock recovery is the only problem (and there are a number of other reasons an OTA update could fail to install), you can definitely use ClockworkMod to install it.
If the update has already been downloaded to the phone, the zip file will be stored in /cache. Just boot into CWM and flash it. If the update hasn't been downloaded, grab zip file yourself (take a look at the OTA update URLs thread) and flash it using CWM.
If you're rooted, don't forget to also flash SuperSU before you reboot, or use some other method to maintain root. OTA updates will remove root regardless of how they are installed unless you take care.
recently, i updated to lolipop, i want to back up my stock recovery.img file, for later OTA updates.
because i want to root my phone and install TWRP, please i need a simple way to keep may stock recovery img file.
thank you

You don't need to back it up. When the new future ota is out you download it, install it later and get the firmware zip out of the ota zip and take out the recovery.img out of the firmware zip. That's the stock recovery. So no need to back it up now.
Lollipop has brought back the ability to boot into TWRP. You can boot TWRP, root then back up recovery and boot with flashify.
I have rooted my Nexus 7 wifi 2012 tablet with TWRP
I don't want to keep un-rooting, applying ota updates then re-rooting my tablet. Is there an easy way. Maybe modified images i can use on a rooted tablet which i can install via the install option in twrp recovery loader.
I also notice that Nexus root tool kit has a ota sideload update option in the advanced menue.
So my question is where are the modifies ota update files if they exist as I don't want to keep un-rooting, rerooting each time to apply official ota updates. I have searched the net and can't find modifies ota updates?
My OTA failed due to root and modifications so I extracted system.img and boot.img from the 5.1 tarball and flashed them using Nexus Root Toolkit. Works well.
I'm going through the same issue - I want to keep running stock, but every time an OTA update comes in, it bugs me for an update until I go through the whole process of finding the files elsewhere, using the Toolkit to flash them etc etc.
Is there a better way to do this automatically? Can I find the downloaded OTA package on the Nexus and just flash it from there?
Since Lollipop, you can't take an OTA in any way (official or sideload) if you've modified your system. Rooting, custom recovery or kernel. Unrooting does not help since the system already has been modified.
Easiest way to upgrade and still keep your data is to flash the factory image but leave out userdata.img. This can be easily done through NRT (No wipe mode) if command prompt is scary. Yes you'll have to reroot... But hey, this is a Nexus, it's easy.
I assume that means waiting for someone to post the update?
If you want to wait for someone to make a prerooted image, then yes. Otherwise just download the official factory image (Google it) and go for it.
Google doesn't always release OTAs and factory images at the same time, so some waiting will probably always be involved...
Drives me crazy. TWRP used to be able to intercept a OTA flash, flash the needed images, detect you lost root and ask to restore root.
Somewhere that disappeared.
I just flashed a very old stock and took every OTA to 5.0.2, rooted, setup... now getting bombarded with 5.1.1 update notification. Ugh

I need to flash the latest lollipop image to my rooted nexus with TWRP. I know where to find the images but don't remember how to flash it. What exactly are the steps and how do I leave out userdata.img ?
And what are the steps to reroot lollipop?
Thanks
i keep getting the offer to download the 5.1 update but when i do it dloads it then tries to reboot into recovery to flash it but it obviously boots into TWRP recovery which is no good.
So the question is when it dloads the update where does it dload to?
and could i flash it from TWRP if i find it?
my phone softbricked after trying to restore my cm12.1 nandroid backup (made in twrp 2.8.6.0, could being on 2.8.7.0 cause this?)
the ota for MM 1/2 is on my phone and I am thinking of flashing it. is this safe?
using a different recovery version can sometimes cause issues with backups.
downgrade back to 2.8.6.0 and try again. Once you are restored, you can upgrade to 2.8.7.0 and create a new backup.
I know I'm a bit late but I hope that I can still help.
You can download a ruu for mm sense 7 update. If you want I can leave a link then download a ruu from ruu.lalleman.net and place the mm ruu zip inside de ruu folder you downloaded and rename to rom.zip . This worked for me

You can't run an OTA with a custom ROM on the phone (need stock, never rooted ROM). And you can't flash an OTA with TWRP (at least, not easily), it requires stock recovery.
