How to update Nexus 6P without losing root? - Nexus 6P Q&A, Help & Troubleshooting

I haven't downloaded any security patches since I followed the main guide and rooted my phone.
I now have seen the news regarding the security update and how many critical flaws there are so I would like to update.
How can I do so without losing root?

Losing root shouldn't really be a concern. All you need to do is flash SuperSU again afterwards, which takes about a minute.

This is an app by Chainfire called Flashfire. It works perfectly for what you want. I have used it myself on a few occasions. Let me know how it worked for you.

+1 FlashFire

If you are impatient and don't want to wait for the OTA zip, just download the factory image and flash the following files using flashfire.
boot.img
system.img
vendor.img
Remember to disable security before you flash or you will have an issue with the vendor.img.

Hey, so I'm rooted with stock ROM and EX kernel but received the April update, any info why I got it?
I thought if you're rooted you weren't supposed to get an OTA update.

You'll still receive the OTA, you just can't flash it via the traditional method.

I remember using the FlashFire method a month ago. The update worked and I didn't lose root, but I lost TWRP in the process.

Yes the update replaces TWRP with standard recovery. But I believe you can flash TWRP with Flash Fire.

I couldn't flash it with FlashFire. I had to reinstall it from PC, which ended up with TWRP asking for a password, meaning I had to end up wiping the phone, which was worse than doing the regular OTA update.

The new version of twrp 3.0.2.0 has been fixed. At least for me it worked.

Nice, I haven't installed the latest TWRP. I'll give it a try.
What I don't recall, though, is if last time I lost the applications I installed by flashing them with TWRP (like viper4android) or which rely on root.

I always remove security before flashing updates. Only issue is setting up the Imprint and adding cards back to Android Pay.

If you use FlashFire just deselect recovery from the list when you load the latest update.

Flash stock recovery and then ADB sideload the update. Links can be found in general. Then when it's done reflash twrp and SuperSU. Pretty easy. I've done it.

Update problem

I am trying to update my tablet to lollipop. But every time I do the OTA update it makes it halfway through and says Error. I would like to update to lollipop and then root it again. What should I do. I was rooted at one time. I even did a factory reset and can't get it to update.

Is your bootloader unlocked? Have you tried flashing the official factory image through fastboot? The most friendly utility in this situation is Nexus Root Toolkit. You can get root easily with it as well as unlock bootloader, flash kernel, rom, basically everything. I'd really suggest downloading that.
It was and it updated to 4.4.4 and I lost root. So I can use the root tool kit to update to lollipop?

I'm not sure, but I think you can. Search the web for that one. Your bootloader NEEDS to be unlocked in order to update to lollipop. If I were you, I'd flash the image using flash-all script provided in the factory image package. It is fully automated and I haven't experienced a problem with it.
I got it fixed thanks

Found this post through Google after having the same problem trying to apply the 5.1 OTA to a formerly rooted Nexus 7 Grouper. Using the Skipsoft Toolkit to unroot didn't work right, kept producing a aituation where it wouldn't boot Android and attempting to flask the stock image would fail too.
Used Nexus Root Toolkit "Flash Stock + Unroot" option to return to stock, and then applied the 5.1 factory image using the no wipe option and regain root and everything worked PERFECTLY. All my user data is even still intact.
Thanks very much for this!
That is what I did too.

So how does OTA work?

As a long time Android power user, I rooted my Nexus as soon as I got the phone. However, I completely forgot about the best thing Nexus devices have to offer, OTA updates.
I completely ditched OTA before since I was on custom ROMs most of the time on other devices.
So here are the questions.
1) How will modifying the system partition affect OTAs? Will they still show up and I won't be able to install them?
2) How can I get OTA back and working? Does a simple "fastboot flash system/boot system.img/boot.img" with the stock system and boot partition fix the issue? If not, what do I do? And will it involve data wiping?
3) If I don't do those, I can still do a manual update for the system partition using fastboot, correct?
Note: I rooted the device using the Nexus Toolkit method over at the dev sub.

Speaking of OTA and systemless. I have opted for the systemless root method. If I want to install an OTA, all I have to do is flash the stock boot image, install update, then re root correct? Assuming there are no changes to system?

Did you double check and did it right? I just updated my 5X and N7 LTE, both did the optimizing app piece that took forever. Erased the cache?
The optimizing apps comes from clearing Art/dalvik cache.

I have issues with the april build, i am not able to see any notifications in my pull down and also quick settings are missing. i downgraded to the march build and it is still broken :/
I also double-wiped everything before flashing the new images..no optimizing apps :-s
PS: For me, xPosed v81 doesn't work with latest build
Just try without xposed installed...

There are no apps to optimize! What are you possibly talking about? And to the person whose flash took a long time due to optimizing apps, you might want to start over and do it the right way.

Oh I see. There are only 2 things I see that happen on an image flash. 4 or is it 8 apps get updated immediately, then all the others start downloading updates from the PS. I think there are about 2 dozen of them in all and it takes forever. I presume that was your experience too. I feel for the guy that optimized because he probably didn't do a factory reset before flashing the new system.img.
Did you restore via Titanium by any chance? I'm having some issues on paid versions of apps I restored. PS says it might be a bootlegged app and denied access to them. I had to uninstall and reinstall from the PS which naturally wiped all my data from the backup. I wonder if I could restore just data? Oh well, all fixed now but this is something new.
It took a long time to optimize my apps because there are quite a number of apps and they were mostly games that are quite large. The process basically recaches the apps since I erased the cache as part of the flash. It's part of the process -
Flash bootloader
reboot bootloader
flash radio
reboot bootloader
flash boot.img
erase cache
flash cache
flash recovery
flash system
flash vendor
reboot
I don't flash userdata since I don't want to wipe user data. After all that, flash twrp and do your usual root, etc...
Try using flashfire by Chainfire (requires root). Simply download the factory image and flash it using the app (make sure to untick flashing of data and select inject root). That way you don't need to use your PC and flashing just take around 2-3 min. If you would like to install twrp afterwards you can do so by using flashify since you're already rooted.

Flashing factory image OTA using flash fire

What's up? I flashed the latest May OTA by following this video https://youtu.be/cvs0JQswTWw
I did all the steps minus the 'inject SuperSU setting' as I was gonna flash thru twrp myself when I reinstalled xposed, However when I try and boot into recovery I see a android with a triangle and exclamation mark.
My device is fully functioning with all my data intact but I am stuck without a recovery.
Previously I was on the April ota unlocked bootloader, stock rom, stock kernel, with Xposed installed. Hopefully someone can help me

To get TWRP back, I would have to reinstall thru adb correct?
Correct. Next time when flashing, before reboot to system, immediately go to recovery and flash SU Beta. This will prevent stock recovery from over writing TWRP.

Installing OTA 7.1.2 whilst having TWRP installed caused soft brick.

I have just installed went to install the new OTA onto my angler, which was done through TWRP, except it seems to have either corrupted or erased my system partition, because now I just get the "No Command" on boot. TWRP still works and my files are intact, should I just flash a stock 7.1.1 image from Google? (7.1.2 is not yet provided outside OTA for angler it seems)

I would download the 7.1.1 stock like you said and then flash boot, system, vendor, and Recovery. You have to be completely stuck before you install any OTAs. This should leave your data intact but I would make sure you have a backup somewhere before you begin

Thank you, I downloaded the stock image, deleted userdata.img from the zip and used fastboot update <image>, that worked like a charm and all my data was left intact. Will update when Google decides they want to let me install the OTA again.

If you still have a copy of the OTA you could install that using ADB sideload from stock recovery not TWRP. But as you say a safer route might be to just wait for the OTA to appear within your stock installation. Completely up to you

How would I proceed with flashing the update?
Flash stock recovery and system and download the OTA then or something else?

My recommendation is to flash boot, system, recovery, and xender. That should leave your data intact and put your to complete stock. I cannot advise on beta programs because I have never done it and I don't wish to just for the simple fact that it is beta. But if you are brave it sounds like you have the right idea.

I was able to flash on rooted 6P by flashing stock recovery. Took a long time at boot animation, and also security is back to January level.

The only way you can do that is if your phone is rooted and you flash it with something like Flashify.
