Issue updating to Android 5.0

I get this error while trying to attempt to update to the latest android 5.0 in twrp...
while installing the new zip file it says:
package expects build fingerprint of google/mantaray/manta: 4.4.4/ktu84p/1227136: user/release-keys or google/mantaray/manta:5.0/LRX21P/1570855:user/release-keys; this device has google/mantaray/manta:4.3/JWR66V/737497:user/release-keys
but my nexus 10 is already on 4.4.4

Your build.prop isn't standard, get the original one, or just use the factory image to update.

what i need to install to correct his to the correct build.prop of 4.4.4?
ps. my last 4.4.4 was updated directly OTA..

Just download the 5.0 factory image, remove -w from the flash-all script and it will update you. Less dicking around that way.

Exactly the same here when flashing OTA via TWRP.
The build.prop file hasn't been modified as far as I know.
Where/how to get the file please?

I found the best way around this is to install the factory nexus 10 lollipop version. It's actually quite easy or even easier than the OTA method. Just make sure you delete the -w from the .bat file to keep all your data. It worked perfectly for me.

Go to this website:

It has detail instruction and jump down to step 3 regarding to -w

I was having the same issue as the OP. So after reading this thread, I've performed the following:
Downloaded Android 5.0 factory image from: https://developers.google.com/android/nexus/images
Followed the instructions at this site, AND MADE SURE TO REMOVE '-w' AS INSTRUCTED, TO PRESERVE DATA: http://www.androidpolice.com/2013/1...riants-of-nexus-7-2012-and-2013-and-nexus-10/
It was pretty easy. I've been waiting about 30 minutes looking at the boot graphic. Hope it turns out OK. But it is easier than playing with the OTA.

After being stuck in a bootloop, I had to factory reset and now all is well.

...i've been having the same issue since the 5.0.0 update.
I even had to perform a total wipe to get 5.0.0 onto my N10, and even after that I still have a bad signature on my tablet. Now the problem is back installing 5.0.2 OTA, and I do not want to wipe everything again. So please where is that build.prop file, and how do I fix it? or rather, what the eff has gone wrong here, why, and who's responsible for unbreaking it?

Yea, I flashed the 5.0.1 factory image later. Now, I tried to flash the 5.0.2 OTA and it said it saw a 5.0.1 signature and was expecting 5.0.1, or something of that sort. It's basically the same issue all over again... No issues flashing 5.0.2 to my kids' N7s that are 100% stock.
My N10 is unlocked and rooted. There must be something in the customizations that cause this issue.

Why not just update using the 5.1 factory image? I run unlocked stock/rooted on my N10, and that's the method I always use to update. Would also do it this way on my N5 and now N6. Just fastboot flash all the images from the factory image manually (READ: EXCEPT USERDATA). You can also skip flashing the recovery if you run a custom recovery. However, for the sake of completion, I include flashing the stock recovery. Then I let it boot up normally. Then I'll boot back into the bootloader and flash TWRP and flash SuperSU. Updating this way is easier for me since I don't have to worry about the OTA failing due to customizations I may have made to the system (especially now with the new way Android updates after 5.0).

I've already had to upgrade my tablet by flashing stock for the last three upgrades, and every single time I ended up havnig to wipe the tablet clean and install and configure everything from scratch. I'm still hoping that at some point I wouldn't have to do that anymore...

could this all be because my tablet is rooted and has CWM recovery installed?

That's weird. I can't remember the last time I had issues using the stock images, and most people seem to be okay doing it. How are you flashing it? I follow Method 2 from this OP: http://forum.xda-developers.com/nexus-6/general/guide-flash-factory-images-nexus-6shamu-t2954008. I just skip the command that flashes userdata, and it always works. I always flash the new cache image because when I would just erase it, it would be forever stuck in the bootanimation.
Before 5.0, being rooted didn't affect upgrading via OTA. Now, however, any little modification to the system (including being rooted) will cause the OTA to fail everytime. Also using a custom recovery like CWM will cause it to fail. So if you really want to go the OTA route, the least you would have to do is completely unroot (inside the SuperSU app itself) and flash the stock recovery. If you've uninstalled any system apps, you have to reinstall them or it will also fail.

My N10 is with stock ROM 5.0.1 and stock recovery but rooted with unlocked bootloader (and custom launcher). I have two questions:
1) I can unroot it through SuperSU. Do I have to switch back to the stock launcher before trying the OTA installation of 5.1?
2) I remember last time I could gain root by simply installing SuperSU. After flashing the 5.1 factory image, can I still get root this same way, or do I have to install, for example, TWRP and then flash SuperSU?
Thanks!

1) No, you can keep whichever launcher you are using whether it be Trebuchet, Google Now Launcher, Nova, etc. since it's more of just an app and not a system mod.
2) As far as I know (or thought), you've always had to flash SuperSU using a custom recovery unless your ROM already came pre-rooted. In which case, all you would have to do is install SuperSU from the Play Store. But to answer your question, after flashing the factory image, you would have to flash a custom recovery like TWRP and then flash SuperSU using said custom recovery. However, that's not complicated at all. After flashing the factory image, it just takes like another 5 minutes to flash TWRP, boot into it, flash SuperSU, boot into the OS, verify root status, then power off, boot back into the bootloader and flash the stock recovery (if you don't want to keep the custom recovery). While you're at it, after flashing SuperSU, why not flash the Translucent Nav/Status Bar Mod found here: http://forum.xda-developers.com/showthread.php?t=2771708 provided by @hanspampel. He's done a great service for us. It's the easiest and best mod for the stock N10 right now that restores the translucent decor that Google decided to disable on our device. I flashed it on my N10 after upgrading to 5.1 and it works flawlessly. But that's just a suggestion.

MotoX OTA Update - XT1060 Blur_Version.212.166.3.ghost_verizon.Verizon.en.US .zip

Edit: The attached zip in post #2 in a minor update the original 4.4.4 release for XT1060 FXZ. Below are the instructions. This is NOT the Full 4.4.4 OTA update.
Instructions to flash
1.) Move zip file from /cache folder to /sdcard folder if you received OTA (Zip file in 2nd post if you do not have it.)
2.) To be safe, disable xposed framework (if you have it running).
3.) Reboot into bootloader
4.) Use mfastboot to flash stock recovery (if not running it)
mfastboot flash recovery recovery.img
Click to expand...
Click to collapse
5.) Boot into recovery from bootloader
6.) Hold Power + Up Button to get recovery menu.
7.) Flash zip file from sdcard.
8.) When complete reboot, then boot into bootloader.
9.) Use mfastboot to flash custom recovery (aka twrp)
mfastboot flash recovery <twrp file name>.img
Click to expand...
Click to collapse
10.) Reboot and enable xposed framework.
11.) Done.
Another suggestion by @KidJoe
After mfastboot flash recovery <recoveryyouwant>.img its long been suggested to do a mfastboot reboot-bootloader then go into recovery, before doing anything else.
We've seen many instances where skipping the reboot-bootloader and enter recovery giving symptoms like the flash of recovery didn't work... (i.e. "old" recovery was still on the phone)

It's far, far more than a 911 bug fix ... there's 2500 lines in the updater script, touching dozens (if not hundreds) of app and files.

Does this require removal of root/xposed or just needs stock recovery?

I generally disable xposed and flash stock recovery but root should be fine. Anyone have a copy of the stock recovery? I'm on the dev edition. OTA's are so infrequent on this device that I forget where I stash the stock recovery all the time.

I got the notification last night, and hid it this morning (turned off notifications for the Moto Updater app). I am on an XT1060 Moto Maker, with an unlocked bootloader. In the past I've flashed /system and /recovery to update (from 4.4.2 to 4.4.4) with the OTA, then reflashed TWRP and flashed SuperSU from there. Do I need to do all that, or just stock recovery?
I do have Xposed, Cerberus and App Ops installed as System Apps, I believe.

I found the recovery for myself at the following link:
http://motofirmware.center/files/file/47-vzw_xt1060_444-kxa2112-l126_cfc_1ffxmlzip/
Might help someone else...You can verify your build by going to About phone. I had Build number KXA21.12-L1.26

For some reason, I cannot use either mfastboot or fastboot to flash the stock recovery. When flashing it, I get the android icon with the red triangle.
Its been a while since I have had to flash back to stock recovery. What am I missing? I have the stock recoverystored for the last official FXZ.

when android with red triangle appears, press vol up for 3 seconds and you will be given option to flash from sd card.

Well, this has locked me out of re-flashing custom recovery, which - of course - means there's nothing that can be done beyond that.
Any version of TWRP up to, and including, the latest flashes without error ... but when you boot, it's still got stock recovery on it.
So no way to root, apply supersu, or do anything.

Anyone got the fxz for this yet?

Ok, figured this out ...
(was able to back down to the original 4.4.4 w/rsd-lite and regain TWRP and develop these steps)
So the following can be done to upgrade to this new version, and retain TWRP (plus you have the new recovery later on for 5.1 when it comes along ...)
First, the presumption here is you are unlocked. If you are not, none of this will work.
Also, you will need RSD-Lite installed and operational.
Download :
https://dl.dropboxusercontent.com/u...RIZON_4.4.4_KXA21.12-L1.26-3_cid2_1FF.xml.zip
https://dl.dropboxusercontent.com/u...4.4.4_KXA21.12-L1.26-3/twrp-2.8.6.0-ghost.img
https://dl.dropboxusercontent.com/u/22067374/GHOST_VERIZON_4.4.4_KXA21.12-L1.26-3/servicefile.xml
Unpack the GHOST zip file, and overwrite the "servicefile.xml" in the unpacked folder w/the one you downloaded, then copy the twrp .img in there.
Fire up RSD-Lite, put your phone in fastboot, and apply this update by loading the servicefile.xml as the update.
It will update everything, installing the TWRP instead of the new stock recovery.
Note: you can delete the twrp line in servicefile.xml if you wish to retain your existing custom recovery.
When done, you should reboot, update, and be up and running with the new 4.4.4 and TWRP ... so easy path back to root via TWRP.

FYI... its already confirmed that you do NOT have to disable Xposed... All you need is stock recovery.

Nougat update unsuccessfull

So i just got the next android update and i downloaded it right away. I clicked the install button and left it in the charger. When i came back it had booted into twrp (i have unrooted yesterday btw). i found this quite odd but is just booted to system and it seemed fine. Then it said it was getting ready to update and rebooted again. Again it booted into twrp. I booted to system again and then the screen with update unsuccessfull.
Can anyone help me with this, i really want the nougat update :laugh:

You've to be on Stock recovery to be able to intall/flash official OTAs from motoroal. TWRP is a custom recovery which doesn't go well with these official OTAs.
Flash stock recovery first & then try to update:good:

It's the same way you used to flash twrp recovery, in (m)fastboot mode use the command-

New update to fix voLTE 911 bug...

So this morning I got an update to fix the voLTE bug. I'm unlocked with twrp installed and rooted. Just for the sake of experimenting I tried installing it. Well that didn't work. Just gets stuck in twrp recovery and you have to power the phone off completely to get it to boot. I guess my question (even though it's a little early) is there a way to install the update without reverting back to stock?
EDIT: Link to the zip
https://drive.google.com/open?id=0BxqNotAWlwLUQ1Fzcjc2YXd4QzA

I don't believe so.
In the past you either had to go back to stock or wait on someone to create a compatible update for rooted devices.

Can you post link to zip?
If you are rooted, you can find the zip in cache folder in recovery.

Can you add what variant and build you are using before the update? Also the build afterwards?

If you have systemless supersu, you should just be able to apply the update after reverting to stock recovery.

So I found where the zip downloads. I wonder what flashing it in twrp would do?

OK, so I tried flashing recovery.img from stock firmware build 33. But the OTA update will not install, instead I get an error after downloading and rebooting (red triangle at recovery mode).
So I tried fully reverting to stock firmware but I decided to skip over erasing userdata. Afterward the OTA downloaded and installed successfully. Keeping userdata does not seem to have caused an issue.
My problem now though is how to get root back without having to wipe userdata after re-flashing TWRP.
Or is this not possible and if I want to root I must first wipe userdata so that TWRP can read internal memory?

Just tried flashing it with TWRP and no luck:
Verifying current system....
E3002: Package expects build thumbprint of 7.0/NPN25.137-35/37:user/release-keys or 7.0/NPN25.137-33/35:user/release-keys; this device has .
Updated process ended with ERROR: 7
which doesn't make much sense since I rooted the stock ROM (Build number reads NPN25.137-33).

If your using a custom recovery flash the stock recovery, then go to the stock recovery and using your computer flash using adb sideboard command. I assume you already know how to do this. Hope that helps.

I'm stuck in the same boat... no idea how to flash the stock recovery and sideboard, what that even means, or if that would break root. I just followed the step-by-step "how to root" video when I first got the phone
There's a workaround to disable the "advanced LTE" or whatever it was called, so I did that. But in the meantime until a more "user friendly" means of updating is available, is there a way I can get rid of this nag screen? Way back on an earlier device (Samsung Charge?) I remember manually editing a "build.prop" file or something to match the latest version so I wouldn't keep getting the software update nag. Is there something that will do the same here, or is there a system app I can freeze in TiB?
My best guess is freezing "Moto Actions 03.022.1.4-N" because it's showing "(updated)" on the side.

What he means is you need to download the stock rom, unzip it, then boot phone to bootloader mode and connect to PC. Then flash the recovery.IMG from the stock rom folder with command prompt:
Fastboot flash recovery recovery.img
Then you can on the phone tell it to boot to recovery mode. This will be a screen with Android on his back and the words NO Command on the bottom. Then plug to PC and use adb command to sideload the update zip like this:
adb sideload [nameofupdatefile].Zip

What he means is you need to download the stock rom, unzip it, then boot phone to bootloader mode and connect to PC. Then flash the recovery.IMG from the stock rom folder with command prompt:
Fastboot flash recovery recovery.img
Then you can on the phone tell it to boot to recovery mode. This will be a screen with Android on his back and the words NO Command on the bottom. Then plug to PC and use adb command to sideload the update zip like this:
adb sideload [nameofupdatefile].Zip

Strange, reflashed the stock recovery and adb can't see it (adb devices returns nothing). And when trying to install it via the normal OTA way, the stock recovery tries to install but ends with an error.

That's what happened to me when I tried reverting to stock recovery and then trying to install update from phone Settings app.
I ended up having to revert to stock rom to get ota to apply with settings app. But now I am trying to root again but after installing TWRP data is encrypted again. So looks like I will have to wipe data before re-rooting.

Problem flashing stock image

I have UB and rooted with magisk 20.1. I rooted the October build by patching the boot image using magisk. I try to flash the new November stock image and it fails. It says
Writing boot
Failed (failed to write to partition Not found)
I think it may be connected to booting into slot a or b. Maybe?
Can anybody help?

You already took the November OTA or are you still on October?

I'm on October trying to flash November

Pretty sure you cant flash the boot image alone. I always flash the stock boot for the build Im currently on then take the OTA. I think there is a new bootloader for November. Not 100% on that though.

I'm just trying to flash the full factory November stock image. I downloaded it, unzip it, plug in the phone in fastboot and double click the run me bat file.
This has always been fine before but I am new to pixel 3a and have only done this once before, on October build. But I came from an original pixel so I've spent 2 years updating that in this way.
I can't work out why the flash is failing.

Try flashing the stock October boot.img then try updating. Ive never been successful flashing an OTA or factory image over a patched boot.

I've tried flashing October factory image and get the exact same result. Not sure what else to try.

Sorry just reread your post. Will try and reflash boot IMG. I do that with fastboot flash boot.img?

Do I need to flash boot.img to both slots a and b? If so how do I do that?

I only ever flash the one in use.
Just fastboot flash boot boot.img is all you need.
Your can also always just clean flash the OTA. Just download it, factory reset, adb sideload the OTA in recovery.
I've done that a few times now.

Thanks. Will try things tomorrow. It's late here in London. But I can't get a twrp.img to work. It doesn't seem to mount the system and I can't flash anything. Have you got twrp to work? I'll come back to you in about 18hrs if that's ok?

TWRP doesn't work with Q. Just use stock recovery to sideload.

Ok, will try when I get home from work. Does the OTA update contain a boot.img? Is that what I need to patch to root again?
Thanks very much

Yes, OTA and factory images are essentially the same thing just packaged differently.
And the easiest way to reroot is to just download and repatch the new stock image, or flash a custom pre patched kernel.

The OTA zip is packaged differently and does not include a boot.img file that we can use. (I'm sure it must be in there somewhere, but not in a usable form). Therefore you must download the "Factory Image" from Google. Unzip it, open it where you will find another zip file inside. Open that second zip file and you will find the boot.img file there. Move that boot.img file to your phone so that Magisk can access it and to modify it.

FYI here are the steps I took to update my rooted 3a this morning:
1. in Magisk Manager select Uninstall and select restore images (I did this because I kept getting a 'installation error' on the OTA page)
2. Like an idiot I rebooted my phone, do not reboot! So I had to reinstall magisk
2a. copy the boot.img of Oct to my phone to have it patched by magisk
2b. fastboot flash boot boot_patched.img
3. the OTA downloaded while I was on the stock boot.img so I just followed the magisk instructions to install the OTA in the other partition
Next month I'll just jump from step 1 to 3 and carry on being rooted.

The simplest way to update when youre rooted is to......
Reflash the stock boot from the current build youre on
Take the OTA directly on the phone
Download stock image from new build and move it to phone
Patch with Magisk and move to your PC
Fastboot flash boot boot.img
Ive done this for the last 3 updates and it works perfectly every time......I obviously substitute my kernel for the patched boot but the process is the same. I find this far simpler than messing with Magisk

Thanks for all the suggestions but I still cannot update.
I have tried restoring boot.img
data reset from recovery
relocking bl - ota fails
Unlocking bl again - won't flash using ADB
There is no problem with the phone being recognised on ADB, the flash Just fails as the screen shot in my opening post. I'm thinking it may be connected to needing to flash to the inactive slot.
Anyone got any ideas?
