[Q] 5.1.1 stock update: Re-root and Unencrypt Q's - Nexus 6 Q&A, Help & Troubleshooting

Many of you have heard by now that 5.1.1 is out, and we should receive an update soon on our stock rom Nexus 6. I just bought a Nexus 6 64gb, XT1103, and it is running the stock rom, rooted, and un-encrypted. I'm wondering if we'll lose root and un-encrypt if we take the update, and loose data if we re-unencrypt. What have your experiences been on the stock rom 5.1 update?

While the update will download, it will not install with root and an unencrypted kernel.
IF you want to take the OTA, then you will need to fastboot flash the boot.img and system.img from the factory image. Boot.img will encrypt your kernel, but you will not loose data (but you will have to factory reset, again, if you want to unencrypt, which will wipe data). Flashing the system.img will remove root and flash stock recovery.

so unroot and encypted will do the trick? what about the bootloader, will it work with unlocked or should it be relocked too?

5.1.1 is NOT officially out for the nexus 6. it is in aosp though. thats two differing things. stock is on 5.1.

The OTA package only looks at system.img and boot.img. Of course you need stock recovery to install it. And the "unroot" option inside SuperSU is insufficient. It leaves some traces around that will prevent the OTA from loading. Flash the stock system.img.
And afterwards, when unencrypting, you'll have to fastboot format userdata. Which will wipe your SDcard again.

Bootloader status has no effect on the OTA.

I have rooted, but encrypted 5.1, and got OTA5 5.1.1, I am on custom recovery,
should I flash stock recovery before flashing? plus, after installing, I will need to regain root access right? my data/apps will stay intact right?

As it says above, you cannot FLASH the update if you are rooted, even with a stock recovery.
You will have to flash the system.img and boot.img of the Stock factory image. IF the full factory image of the version you want is available here: https://developers.google.com/android/nexus/images
...download it, extract the system and boot.img and fastboot flash them. Job done. If the version you need is only available in an OTA file, you'll need to flash the system and boot of the expected version (i.e. the one you're on now) AND flash the recovery to accept the OTA

I am using a custom recovery, on a rooted but STOCK 5.1, and I already got OTA, I downloaded it as well, but needed to make sure before upgrading, that it doesn't cause data lose if I move to stock recovery, and want to regain root after flashing 5.1.1,
anyway, i flashed stock recovery, then proceeded with the update, it tried flashing but showed "error" at the android screen, so, I don't whats missing, as I was using stock 5.1, just unlocked it, rooted it, and flashed customer recovery,

When I said receive, I meant flash. You cannot FLASH the update if you are rooted. Period. Read my post again but substitute the word receive for flash.

got it, but still looking for the answer, will I loose data after flashing system.img? or while regaining root after 5.1.1 update?

No. Only factory reset or unlocking the bootloader loses data. System.img is the rom, flashing to /system. Boot.img is the kernel, flashing to /boot. if you flash these separately, userdata.img is not flashed to /data, so your /data partition remains in tact.
root doesn't touch /data either. Just /system

Yeahhh I get that now. It's got to verify that what's already there matches what it's supposed to be updating.
I'm looking here because I'm on Fi now, and there are more implications there than I realized before. Not that those matter too much, I do want stock. Just trying to see how I can stay current, be rooted, and not break Fi. Thankfully it's a Nexus device so it's not throwing up insane device restrictions blocking root access.
I want to be able to update system and boot, as they come available, with a recovery like TWRP or CWM. Then reapply SuperSU flash after that. What I'm not sure of is whether I can even do that. I'm fuzzy on the whole " encrypted device" thing. Does that apply to the images at https://developers.google.com/android/nexus/images#shamu
Would I be hosed if I took the system and boot images and flash those to update from one version to the next?

You absolutely can, it's just that if you wish to decrypt, you'll have to format data. I've had this device, since launch and I'm still encrypted. Not an issue for me. But you can just flash, individually, everything but userdata and keep your data intact, each time a new image becomes available. Then just flash TWRP and then SuoerSu from TWRP. If you've unencrypted, OTA won't flash. You can always update manually.

edit - this was a duplicate. i can't delete it.

Oohhh, wait, so flash from fastboot, except flash SuperSU from TWRP? (update.zip style?) Is only the data partition encrypted then? If that's the case why are folks decrypting? Unlocking the bootloader requires it, but what is that required for?
And thank you loads BTW! I'm so far behind! I'm coming off 3 years of rooted, stable SGS3 stock, last updated to 4.1.2. There were no further stock updates that I wanted, (too many bugs) and everything was working so I left well enough alone.
(I probably would have messed about with CM and other roms, if I had not initially bricked the thing trying to put TWRP on... and had to send it for somebody to JTAG reprogram it. Thought about it several times, but never wanted to chance it again.)
Thanks again!

[Q] Error while installing 5.0.1 update

Hi I just got the 5.0.1 update, I downloaded it and the phone rebooted itself, I got the installation screen and after 5 seconds I just got the word "error" and I had to restart it manually; the device is rooted, have anyone else had this problem? I would appreciate your help

With lollipop you can't take an OTA if you are rooted or running just about anything else modified (custom kernels, like ones that have force decrypt disabled also will cause it to error out).
You can still flash it manually by flashing the images. If you don't want to wipe, don't flash the userdata.img . Also, if you aren't currently encrypted, booting up with the stock kernel will force encrypt your device, so don't flash that if you want to stay that way. You can then re-root. There are more in depth instructions for doing this out there if you search around for them.
My Nexus 6 took 5.0.1 just fine, but my Nexus 7 does this same thing, running stock ROM/Bootloader/Recovery/etc. The ONLY thing done to it is the Fastboot OEM unlock, but I doubt that alone would stop it. I'm curious to know what resolves this ( other than downloading the factory image and flashing it without wiping the userdata )
Just got same error. I didnt even root phone, bought it today, it installed apps from backup of my previous Nexus 4 and OTA is failing.

So basically the only way is to flash the image manually? If I choose not to flash userdata.img my phone data (photos, contacts, apps, etc) won't be erased right? But I will lose root correct? Thanks!

Correct, with Lollipop if you modify things you basically are then forced to manually take the updates. Not that big of a deal as you would likely be needing a PC to reinstall your custom recovery or re-root anyhow after the update.
Flashing userdata.img isn't necessary to update. Neither is recovery.img if you want to keep a custom recovery.
Also as I mentioned before, if you have disabled encryption on your device, if you flash the stock kernel (boot.img) and boot up with it you will re-enable forced encryption. You will need to flash a kernel with force encryption disabled if you want to keep running without encryption. If you haven't disabled encryption, or don't care if your device re-encrypts (this doesn't erase anything, just may take a few minutes on first boot) then this doesn't matter.

Can I manually update without removing root first? Am I going to receive an error if I don't remove it? based on what you said, I will remove userdata.img and recovery.img and that will not wipe my data right? Do I have to decompress those files or the flash-all.bat will take care of that? Thanks!

I'm interested as well. Mine is rooted and I have encryption disabled, and I have TWRP on my phone. I tried to sideload the OTA update, but I can't get my phone to start sideload. I even flashed the stock recovery to get it to go, and no dice. What do I do next?
Anyone? I would appreciate the feedback, thanks!
sideload refers to adb as I understand it. thats NOT how you flash....you use fastboot to flash so you can do it all by hand or use one of the toolkits that script it for you.

If your doing from the PC you need to extract the zip file from within the image and then fastboot them. As for root, when you do it from fastboot I dont believe it matters as you will lose root anyway and need to re-root via flashing SuperSU.zip
Worked great! Thanks! Android 5.0.1 and root, no data deleted
Is it normal to not have received an update beyond 5.0? I have had a Nexus 6 since day one, no rooting of any kind and I have not received 5.0.1.
I have done the sideload method, but I really don't want to bother with it. I do however want some of these terrible bugs I am experiencing squashed. This phone is giving me lots of issues lately.
Thanks!
Can you receive and install OTA updates with an unlocked bootloader? Everything else is stock, no disabled encryption or anything just unlocked bootloader.

If you're planning to stay rooted (meaning no OTA in future) system.img, boot.img and radio.img in any order.

If you use fastboot, just run these commands in terminal (I used windows, so in order to flash using fastboot, put the image that you downloaded for the update in the same folder where you have fastboot and open a terminal there) you can rename the .img files to whatever you like and replace those name in the commands below:
fastboot flash bootloader <bootloader file name here>.img
fastboot flash radio <radio file name here>.img
Then reboot it:
fastboot reboot-bootloader
Then flash these:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
And that's it. These commands are run while the phone is connected to the PC, you have to turn it on by pressing volume up + volume down + power.
Good luck.

[Q] OTA Updates on Rooted XT1095 (Stock Recovery)

I recently followed this guide to root my XT1095. All I did was unlock my bootloader and boot the image...I did not (intentionally) alter my recovery, nor did I install a custom ROM. Will I still receive OTA update notifications and, if so, are they safe to apply?

If you are running a custom recovery TWRP for example, I doubt that you will get OTA updates. I believe you need the stock recovery to be able to install OTA updates.

I'm a little confused by your response. As I said in my original question, I did not (intentionally) alter my recovery. Did the method that I used achieve root alter my recovery for me?
If you did not install a custom recovery than you should be able to get OTA updates. Check to see what recovery you have.

As long as you don't make any changes to /system, you *should* be good to go for updates. If you didn't intentionally flash a custom recovery then you still have the stock one.
If you're rooted OTAs won't work. In KitKat and lower they just performed checksums on each file before updating, so the altered root files were left untouched and the update installed. In Lollipop and up (at least for Nexus devices), it does a total checksum and if /system has been altered in any way (including for root) OTA's won't install.

Thanks for all the responses, guys. I booted into recovery and saw this, so I think my recovery is still stock. One quick question: when I boot into fastboot and select "Recovery", I get a dead Android and a "No Command" prompt - I had to follow these steps to actually get there. Why is that?
I'd like to try out Xposed now that it's available for my device, and I see that requires a custom recovery. If I install a custom recovery (TWRP, for instance) and use it to flash Xposed, can I then revert back to stock recovery and continue to receive OTA updates?

If you modified your system with Xposed you won't be able to install OTA updates. Even if you return yo stock recovery.
To install an OTA you need three things. 1. Unaltered system, 2.no root and 3. stock recovery

You can always flash a ROM or custom ROM via fast boot, but you will loss all your settings, apps etc because you are flashing an entire new system... The OTA only patches
The only way back is to flash your stock ROM if you can get a hold of it.

Repeat of Question
I'm not sure I completely understand what I need to do to get updated to 5.1. I have an XT1095 that I only rooted, no custom recovery. I downloaded the OTA for 5.1 last night and tried to update. Got an error and it did not update. A quick google search seems to state, as well as earlier in this thread, that I can not update if I am rooted. I would prefer not completely start over on my phone (wipe) and would like to just apply the update. Can I just "unroot" my phone and apply the update or do I have to go back to the beginning (with a stock recovery) before the update will take?
I know enough about all this to have followed the directions to accomplish the root about 7 months ago. Since then not played with any system files! The only reason I rooted was so I could use the full capabilities of Greenify. Any opinions on that would be appreciated as well. Thanks!

It's more difficult with Lollipop: updates now "look for" a completely stock unmodified unrooted system. So you'll have to flash a stock image of the current build and then take the OTA.

[Q] Ultimate Guide to 5.1 OTA - unencrypted device

So I've read a couple threads on this, but I'm still confused.
I want to update through OTA, but not encrypt my phone, ultimately.
Is this how it's done?
Flash Stock system, boot, bootloader, recovery (5.0.1)
Boot to stock recovery, adb sideload OTA
Reboot to bootloader
Flash custom boot w/o forced encryption
Reboot?
I think when I unencrypted back then, I had to make a full wipe? I want to avoid this.

It would be best to wait for a 5.1 no-force boot.img to be released first. And also, wait until the 5.1 systemn.img is available. Then flash 5.1 system.img and the nboot.img of your choice.

The only change we're expecting is that they may move from software to hardware encryption.
Though you could test it if you believe that to be the case.

It would be best to wait for a 5.1 no-force boot.img to be released first. And also, wait until the 5.1 systemn.img is available. Then flash 5.1 system.img and the nboot.img of your choice.

is there no way to create a 5.1 no force boot.img from the 5.1 OTA or from the system files on the phone after the 5.1 OTA was applied?

I don't know enough about unpacking boot,imgs to answer that.
I am also looking for the same thing. Sideload the OTA zip file and keep it unencrypted.
I am currently on FK and I was thinking to do this:
Flash stock 5.0.1 boot.img
Sideload the OTA
Flash unencrypted 5.1 boot.img
Of course no reboots in between to avoid the encryption.
Any thoughts?

We got the factory images now, so you don't have to flash 5.0.1 first.
5.1.0 Shamu
Is there an unencrypted 5.1 boot yet?

I messed it up. Flashed everything (but the custom boot.img) and then tried to root (Cause I wanted to flash a mod through twrp) which lead into a boot which I didn't interupt quick enough.
It now just says "Encryption unsuccessful" and that I have to reset it. I even tried flashing everything again (including new unencrypted boot.img) Oh well.. Most stuff was backed up so whatever..

[Q] 5.1.1 OTA while rooted?

I've been receiving the prompt to update my N6 to 5.1.1 for the past few days, but whenever I attempt to install it, it says it's rebooting and does nothing. Is this because I'm rooted? Besides being rooted, there's no modifications to the system (well, except for Franco Kernel and MCR I suppose...). Is it even possible to update this way? Any help would be much appreciated. Thanks!

Hi, no modifications to system (including recovery) or boot can be present for OTA to flash. Look here:

Well that's a bummer! Thanks for the link. It looks like sideloading will still work, is that correct? If so, is it possible to sideload an update without wiping my data or factory resetting?

If your bootloader is unlocked, just do this:
Download the factory image for the new build you want.
Extract twice to end up with the bootloader, radio, boot, system, recovery, userdata, and cache images.
Flash each image individually with fastboot except for userdata.
You will be updated and won't lose data. Then, just flash TWRP again and then from TWRP, flash the superSU zip. You will be stock rooted, with TWRP recovery. All your data will remain.
If you try to flash official OTA via sideload, it will still fail because of root and custom recovery.

I will definitely do this! Thanks. They haven't posted the Verizon 5.1.1 to the image site yet, so I'll have to wait a bit I guess. :-/ Thanks!

Systemless root (Android 6.0) - Method for easy future OTA updates

I am looking for an easy way to be able to receive OTA updates after rooting with the 'systemless' root method, the steps I mention below assume that the system partition remains untouched after rooting. I have searched and not found a clear answer on this.
Would I be correct in assuming that this procedure should work to receive an OTA update and keep stock recovery after rooting?
Start with completely stock Android 6.0
fastboot boot twrp-recovery.img (boot TWRP, NOT flash, to maintain stock recovery after rooting)
Flash systemless root with TWRP
OTA arrives (Android 6.0.1 for example)
fastboot flash boot boot.img (with stock 6.0 kernel, root lost)
Accept & install OTA update
Success?
So unless I am missing something, this method would leave the system in a stock, unrooted state after the OTA is installed, and could be repeated for future updates. Anybody have any experience with this yet?
Sounds like it will work, but why mess with the ota? More work and risk honestly.
Since you're already using fastboot just flash the newest boot and system.img. Then flash/boot twrp and flash su like you'd need to do anyway. Done. You don't lose anything flashing system.

That is true, kind of just wondering/gathering information. It just seemed like with the new root method, OTA would be possible and less risky than before.

@quakeaz there is one step missing on your guide. After boot.img you also have to flash stock recovery.img. From Lollipop, Google is also checking installed recovery, and for successful OTA, it has to be stock as well.
Otherwise, your guide should work, I've done same thing with my Nexus 5 and 7 for like last 3 months.

Thanks for your reply, but I intentionally left that step out, due to step 2 in my list. By only booting TWRP, instead of flashing, I assume stock recovery will remain after rooting.

Ah, sorry, I overlooked that.
Since I have flashed TWRP instead of stock recovery, I'm going by same process as you write, just reflash stock recovery. And can confirm, that the process is indeed working (no need to install system.img, as with previous system-based SuperSU).
Sounds good!

Instead of fastboot flashing boot.img, you can use "Settings --> Full Unroot" in SuperSU. During SuperSU systemless flash, your old boot image is backed up. Among other things, the full unroot option will restore the backup, assuming it hasn't been lost due to a factory reset and whatnot.
On many firmwares, this procedure also restores stock recovery. This requires that both the firmware supports recreating the recovery from the boot image plus a patch file (most do), and that TWRP did not remove said patch file (which some versions do).
That being said, if you're using fastboot anyway, flashing boot, recovery, system and vendor manually is always the safest thing before an OTA.
Thanks for the info. So I take it while using systemless root, installing ota without unrooting is a big nono? The January ota just downloaded and is asking me to install, should I do it manually?

Thank you for this thread and the procedure. I tried myself to avoid as much as possible to use a computer for super easy OTA update. But there is always one obligatory step: to root the phone.
Phone systemless rooted (2.66) - TWRP installed - OTA arrives.
In SuperSu app : Fully unroot
Install OTA - success
Fastboot boot (or install) TWRP
Flash superSu 2.66.zip
And that's it!
My question is the following: Does it exist a possibility to load on step 3. something that could flash superSu.zip from within the phone, no computer required?
Maybe FlashFire? I guess not, for it needs root and the point is to flash a rooting zip... You see the loop there...
Would it be theoreticaly possible at all?

Yes, this is one of the use-cases of FlashFire. I just haven't finished updating it to 6.0 yet.
Oh nice!
I didn't know it cause I never had the chance to try out FlashFire.
Thanks so much for everything you do for the Android community!
Cheers!

Did you modify system?
Try flashing system, boot, and recovery.
Then try again.
Hi, I have a Oneplus One and today has been released an OTA, so I tried the method. I have COS13 JK (latest full rom) firmware, with systemless 2.84beta supersu and twrp.
The only apps that have root access are AdAway and Greenify (without mods to system apps). No Busybox installed.
I reverted via fastboot to original JK boot.img and recovery.img, and restored, via Adaway, the original hosts file, then I applied the OTA via stock Cyano Recovery, but update failed ("system partition has unexpected contents" error).
Why?
Thanks.
you have to unroot first from the app.Revert to original boot. and then flash

I tried: no way to install OTA, I had to wait for the full rom, and dirty flashed it via TWRP without a problem.
Then I rerooted.
Bye!
ok i seem to be getting the run around on where i need to be to ask my question(s)
i am very interested in systemless root....
that being said i am clueless and all info i am findingis just super confusing me.
if someone could humor a noob to systemless rooting that would be greatly appreciated!!
i recently bought 2 new phone for my household, both are the lg tribute hd (also called lg x style)
one click root and pc method of kingoroot etc dont work... i cant locate a twrp or a cwm for this model easily by searching so i am assuming there isnt one (maybe someone could located or help to build one?)- or maybe im not tech smart enough and i can use any?(i dont think so)
model is lg ls675,android 6.0.1, kernel version 3.10.49, build # MXB48T, software is ls676zv3
main reason at the moment for trying to get root is to remove bloatware and to be able to wifi tether without limitations buy the provider, on ther phone that i have obtained root on i used an app called WIFI Tether Router which works beautifully but requires root...
please help as this is how we use our computer with internet and its beneficial all the way around especially to get rid of bloatware and keep device running smoothly...
thanks again for any help. greatly appreciated.
if im not in the right thread please kindly direct me to the correct one. thanks
