can't install seceirty updates - Nexus 6 Q&A, Help & Troubleshooting

so my nexus 6 was rooted i unrooted it and tried to update the security update and it gives me and error saying my phone is corrupted. Is there any way to fix this?

Removing root isn't enough. You have to be completely stock. That means no custom kernels, no TWRP, and no modifications to the system partition of any kind.
If your root was systemless, removing root may not have restored the stock boot.img. A modified boot.img would prevent security updates from installing.

i didn't do anything to my phone after i rooted it. will wiping the whole phone work?

I don't believe wiping will work, but try it anyway. In the likely event it doesn't work, connect your N6 to your computer, download the latest ROM image from Google, and flash it using fastboot.

thank you for the info

[Q] Sort Me out on 4.4.3 update

The more I read the more confused I get. Could someone sort me out?
<complain>I got the moto x because of the quick OTA updates. Now it seems that because I installed TWRP and froze a few apps with TB that this feature is totally borked!</complain> is that correct? I cannot update without stock recovery and all the original apps installed / unfrozen?
In my predicament would the easiest thing to do be
1. Unfreeze any system apps I've frozen.
2. Use msfastboot to reflash stock recovery?
3. Accept the OTA or somehow flash it manually (I'm not sure about this last one see below)
I accidentally accepted the OTA download and now it bugs me to install. I won't install because it just reboots into TWRP. But it does keep prompting me to set at time to install. If I simply flash stock recovery I think i will still get this prompt. Would that be the easiest way to go?
Thanks for any advice.

1. - You do not need to unfreeze apps. The apps are still there untouched in the file system, and in recovery the OS hasn't booted enough to know that the apps are "frozen". By the way, frozen apps are basically just tagged in the OS as not available....so with the OS not running (just recovery is), they aren't "frozen" in recovery.
2. - Yes, fastboot to flash stock recovery. Boot to bootloader mode, fastboot flash recovery recovery.img (you don't need mfastboot for recovery, though you can still use it.)
3. - Accept the OTA. Since yours is trying to install, you should be able to boot to bootloader, flash stock recovery and on reboot it will start the install of the OTA. When done and booted.....reflash TWRP if you like.
That would be the way to go, yes.
Flash stock recovery and try to upgrade. If you cannot, try to unfreeze all sys apps. That should do it. ?
OK. So maybe not such a huge PIA as I had thought. I will track down the recovery file and read the instructions for flashing.
Thanks

Every time another OTA comes out, people who modify their phones ask the same question. I've written up a FAQ based on the past OTA's.. -> http://mark.cdmaforums.com/MotoX-OTA.html if you want to read it to get more info.
Part of the issues you are talking about when taking an OTA is that the OTAs want to patch and replace only SOME files on your phone, so it checks to make sure the update is for your phone and its android version by evaluating certain files on the phone, that they exist and that their check sums match what the update expects.
i.e. change/modify/delete files the OTA update checks before installing, and the OTA will refuse to install.
If it didn't do this, the wrong update could possibly flash to your phone, replacing files with incompatible versions and making a big mess.
So yeah, "getting back to stock" (or as close to it as you can) is always recommended before taking an OTA so the "check" doesn't fail and prevent the OTA from applying.
In the past, freezing apps with Ti Backup was enough of a modification to cause the OTA's to fail. So often it is still suggested to un-freeze those done with TiBackup.
The OTA zip file (as downloaded) will only flash from Stock Recovery. TWRP and CWM for example don't properly process and flash them, so if you try to install when stock recovery is NOT on your phone, you get stuck in a bootloop. Using mFastboot to flash stock recovery back on is fine for those with unlocked bootloaders. Locked Bootloader users, is another matter.
There is a way "side load" the OTA, IF you have stock recovery, your phone hasn't received the push from Moto or your Carrier yet, and the OTA Zip file has leaked. But it still requires you get back to stock, etc. just as if you were getting it OTA.
So I've tried to flash back to stock but am having an issue. Does anyone have a link to a stock recovery image? Maybe the one I have is corrupt.

How to Handle OTA Update on Rooted Phone

I have a 1095 Moto X 2014, rooted, running stock OS (22.21.11.victara_tmo.tmo.en.US). For the past several weeks, my phone has been asking me to take an OTA upgrade (5.0 -> 5.1, I believe), which I've been avoiding because I'm concerned it will either fail due to root, or cause me to lose my root privileges, forcing me to wipe my phone to regain root. Does anyone have any advice for the best way to handle this? I'm okay with wiping my phone if there's some clear path to restoring my data and settings using Titanium Backup, Nova backup/restore, etc. I know this is sort of a general question, but I'm just looking for a clear workflow for backing my phone up, taking the OTA upgrade and then restoring everything while maintaining root. Any advice would be greatly appreciated.
There is no way to retain root for the upgrade. My suggestion would be to download the full 5.0 firmware, the flash just the system image and recovery image. This will remove root and everything should be back to stock. Then you can take the OTA to 5.1. After that just reroot the phone. No formatting or factory resets are necessary. However I do still recommend doing titanium backup before this just in case.

So, more or less do:
1. backup
2. fastboot flash recovery recovery.img
fastboot flash system system.img
3. reboot, take OTA update
4. re-root with CF-Auto-Root
Does that sound right?
Yes, assuming CF-Auto-Root will work with the latest firmware. I actually never tried it. Normally I flash back TWRP and flash the SuperSu.zip.
This worked perfectly! The only little hiccup was that adb had problems sideloading the SuperSu zip, but TWRP ended up taking care of root for me...it was totally seamless, actually. I am now 5.1 + root and retained all my settings, etc...thanks!

best way to update rooted N6 ?

My N6 is rooted, SuperSU and TWRP. On build LYZ28J and want to update to LYZ28K.
It seems I have 3 ways to do this:
1. Use settings in SuperSU to fully unroot, AND flash the LYZ28J recovery.img to replace TWRP. Then I can take the OTA. After that I can rerun the Chainfire Autoroot script and flash TWRP. So i'm updated with no data loss.
2. Flash the factory image. No need to unroot or remove TWRP, but all data is lost. And I still need to reroot and reflash TWRP. Correct ?
3. sideload the ota zip. Just run adb sideload <ota.zip> . No need to unroot . My problem here is that the only place I found with the ota zip is on Droid Life, not a google url. I like Droid Life, read it all the time, but still... Does anyone have a google url link to the OTA ?
Is there another method?
How are others upgrading? Is #3 as easy as I described ?

1. no. to fully unroot, you need to flash a factory image. if you just remove root, itll still think tour rooted because system files have changed. so, wont work.
2. you can, but why? you gave extra time that you want to burn?
3. nope, cant flash an ots while rooted ir havd chsnged system files.
4. just flash the system.img of a factory image ehen it vomes out, and you will not lose data, but will upgrade.
I've used this thread (http://forum.xda-developers.com/nexus-6/general/using-image-to-update-nexus-6-data-loss-t3053158) to update within Lollipop through several versions. It is always best to wipe data when going from one version to the next (Lollipop to Marshmallow) but as long as you are staying within Lollipop this should work fine.
Check this out, http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052
IMO, easiest way. DL zips to internal storage, wipe, and flash. READ the "Read Me" in the first post. When you update it will get rid of SU. Once you boot with update the first time, you can go back and root with TWRP.
Chose to use this. Did not flash the new recovery image. Updated fine, BUT locked and no root, no TWRP. I'll need to run oem unlock again, wiping all the data.
Sigh.
Wrote too soon. SuperSU and TWRP were gone (even though I did not flash recovery.img). Developer Options was gone. So I needed run CF-Autoroot and still need to flash TWRP. But all apps and data remained.
This is great news, especially if we're going to get monthly updates.

Rooted phone stuck on rebooting after attempted system update

My phone is rooted running a stock 5.1 ROM.
I just got a prompt to install a system update with a security patch, etc so I clicked to install but it gets stuck in TWRP recovery instead of installing the update.
So now every time my phone boots up it restarts trying to install that update.
EDIT: Ok, after a couple reboots the update cancelled on its own. Now I'm wondering if there's any way I can still install this update without it getting stuck in TWRP.

In twrp erase cache. That will erase the update file that downloaded.

Thanks yep that's what I did so it boots fine again. I read in another thread some issues people are having with installing this update if their phone is rooted so I'm just gonna skip it. I've grown tired of all the hoop jumping Android requires.

If you have a custom recovery, you can flash this rom:
http://forum.xda-developers.com/moto-x-2014/development/rom-xt1095-flashable-stock-rom-t3185945
It has the latest stagefright patch now, and it has OTA disabled to prevent bricking issues for people that have downgraded systems or systems that are modified with root/xposed/busybox/etc.
Before I do that, will I have to reinstall my apps or change all of the system settings again? Sorry, it's been a while since I flashed a ROM, I can't remember what's affected.
You shouldn't need to factory reset considering this is a stock rom and you are coming from the same android version. 5.1 to 5.1. But the fact that your phone had issues before may be an issue. You can try it without factory reset since it won't cause any damage to see if it works.
As far as what is modified, it should only be system apps. Anything you installed or configured should remain the same as long as you don't factory reset.

You have to go back to stock rom first to ensure you have system partition 100% stock. You can just flash the system.img and recovery.img, then apply the OTA. If you want to do it from twrp, you dont need flash the recovery.img and apply the zip file from romracer.

I had the same problem. I cleaned cache and was able boot properly. But now my phone asks me to update every 2 minutes and it is annoying the crap out of me. If I unroot and remove TWRP, will I be able to update to this OTA.

Haven't been able to update since LMY48I. Trying to get on Marshmallow now.

Okay, I haven't been able to update since LMY48I. Back then I was on stock recovery. Re-locking bootloader and all but still was not able to take OTA (always came up with dead android guy with "Error"). I'll skip the (probably) irrelevant stuff since then and give you the current situation:
Currently unlocked, rooted, with custom recovery. Still on LMY48I. I can't take OTAs obviously, and have tried flashing OTA updates manually with no luck and have tried flashing the entire Marshmallow image and that will not work either (sideload or flashing from internal storage in recovery). Sideload comes up with Closed error (device DOES show up in device list and I can do other things). Flashing from within recovery just says "Failed".
Please help me get to Marshamallow!
Edit: On Project Fi by the way.
Edit 2: Also, I've tried the flash-all script.
Now it says the device is corrupted when I boot up. I can still access recovery. Any help walking me through getting all of the correct firmware and latest build on would be much appreciated.
Thank you.
Edit: Looks like i'm good. I flashed each .img individually. I'm super curious why flash-all, sideload, and flashing from device wouldn't work though.

Flashall.bat stops; only m-bootloader and m-radio are flash. Google's fault. You did the right thing by extracting the images and fasbiot flash them.
You cannot sideload the full factory image or flash from storage. Only fastboot
And just to clarify, you can't take an OTA (sideloading or otherwise) if your phone is rooted, have a custom recovery or a custom kernel (or any other modification to the system). The state of the bootloader (locked or unlocked) does not affect the ability to take an OTA update.
