4.4.2 (KOT49H) update fails on rooted device

Received the update today but it failed to install. I'm running the stock rom KRT16S. My Nexus 10 is rooted and my recovery is TWRP 2.6.3.1. I have added nothing else to this rom except a few apps from the google play store. I wanted to try again but couldn't find where the OTA is stored. It wasn't in the /cache/fota folder. So I downloaded a flashable zip from the net. But this update file failed to install also. I've seen a few others have success installing the update. I just don't know what's preventing me from updating. I welcome your suggestions. Thanks.

Same here on my Nex5.
It seems, that some custom zips changed my stock (rooted) rom in this way that I am not able to install the 4.4.2 update.
I got similar issue on my Nex4 in the past, I could help me out by flashing full rom (rooted) deodexed, but where can I find the full rom of 4.4.2 for my Nex5 now?
Anybody can give me a clue?
Thank u very much.

Hi Fred, and greetz from Ohio. I'm not aware of anything in the 4.4.2 flavor right now for the Nex10. I'm not sure about the Nex5. I think we're just going to have to wait. But I'd like to have the same thing. A lean & clean deodexed stock rooted 4.4.2 rom with a few performance tweaks. Like the old "Cleanrom" by scrosler. As for right now, did you try an ADB Sideload update to 4.4.2 using Wug's Toolkit? http://www.wugfresh.com/faqs/how-to-update-ota-not-working/

Hi,
You can try performing a full unroot in the SuperSU app if it still doesn't work... I had to adb sideload mine to work, don't know how it works with toolkit, but you have to first set your tablet to receive it. As you are on TWRP you simply go to advanced and select adb sideload, then try using the tool, or following the instructions on it to do so .
You cannot install a OTA zip like a Custom ROM zip, they are a little bit different hehe.
Hope this helps,
~Lord
PS.: This will work for N5 too.

I somehow got the idea that rooted Nexus devices with a custom recovery could handle OTA's without trashing the recovery. I guess I expected that I would lose root. I think I'm just going to wait for someone to put together a "CleanROM" based on 4.4.2 or newer. I've been waiting for a rom like this since I bought my Nex10 anyway. I don't think I'll suffer too much running on 4.4 until then.
Thanks to those who contributed, I'll remember your suggestions. Especially if I end up waiting a long time for a 4.4.2 based Cleanrom.
Update: Thanks to Wug's toolkit. I'm now running 4.4.2..

I should ask for a sticky for this but these instruction will work EVERY TIME if you are running either custom recovery or Root.
You will need the latest adb/fastboot from google, you can either install the SDK or download any of the many smaller adb/fastboot and libs for your os
You will need STOCK 4.4/4.3/4.2 recovery depending on what version of android you are currently on. Download the factory image from here. Open the zip within the package and pull out recovery.img and rename it stockrecovery.img
Copy your custom recovery to the adb folder name it twrp.zip or short name for whatever you are using I am using twrp.
You will need the correct OTA you are seeking to apply - rename it to something short simple and obvious - for this example I will use otaupdate.zip
If you wish to root get the latest patch (I believe its up to 1.75 now) and copy it to the adb/fastboot folder.
BACKUP YOUR DEVICE FIRST AND COPY IT TO YOUR PC
If you are already Rooted:
If you are using SuperSU - go to the application options and completely unroot and reboot if needed
BACKUP YOUR DEVICE FIRST AND COPY IT TO YOUR PC
If not rooted start here:
I am assuming most of you are Windows users. Open your file explorer and open the ADB folder.
On the left hand folder where ADB is located press shift and right click the ADB folder and select "Open command window from here". This will open a command prompt window for you to run all your adb/fastboot commands from. This is the same folder where you copied your recoveries and updates to.
BACKUP YOUR DEVICE FIRST AND COPY IT TO YOUR PC
Copy your custom recovery and stock recovery to your adb folder
Copy and rename the OTA to the adb folder
Copy your root.zip patch to the /sdcard downloads folder (if you wish root)
>adb reboot bootloader
>fastboot flash recovery stockrecovery.img
>fastboot reboot-bootloader
Go into recovery and wait till dead droid appears
Press power and Volume Up at same time to go into the stock recovery menu
Using the volume buttons move and down the blue list of options and select: Apply update from ADB
You will now have orange text at the bottom of the screen - follow the instructions to side load by typing >adb sideload otaupdate.zip in your command prompt window
Wait and watch the progress, at this point you should see the ota processing steps of which there a few and will vary depending on the package. When its complete there will be a "install complete" or similar message
Reboot and let the update complete the system optimizations and go in validate your device is working and the version is what you wanted
>adb reboot bootloader
>fastboot flash twrp.zip
>fastboot reboot-recovery
Using your newly installed custom recovery you can now apply zips/root etc
Reboot as needed and update root if using older .zip to current binaries and enjoy your updated device.
And yes you only need to backup once prior to starting but many people skip that step -DON'T BE ONE OF THOSE PEOPLE.
Hopefully I've not missed a bit.
You can also use these same instructions if you're stuck in boot loop or applied a patch without first replacing stock or unrooting - just boot to bootloader using fastboot and replace recovery and apply the patches. This will usually work just fine and prevent much heart ache on your part.

How I got the 4.4.2 update to actually update...

When I tried to update my rooted stock N7 to 4.4.2 from 4.4.0, the script always failed saying "debuggerd has unexpected content."
This is apparently a known issue revolving around stickmount. Unfortunately, I didn't have a replacement debuggerd and didnt' want to take the time to find and install the right one... So, if you need a quick list of things to do to get the update working (Used Windows 7)
Please note that
:
1) Download
the stock 4.4.0 image from https://developers.google.com/android/nexus/images#nakasi
the Android SDK bundle from here: https://developer.android.com/sdk/index.html
SuperSU from http://forum.xda-developers.com/showthread.php?t=1538053
The actual update file if you don't have it already (mine was already in /cache when I started down this road)
Install the Android SDK.
Run the Android SDK manager and make SURE you get the USB drivers.
Enable Android debugging on the N7 and plug it in via USB to the computer.
Once it fails to find a driver for one of the options, open the device manager.
Locate the "Nexus 7" in "other devices"
Right click and select "update driver"
Tell Windows to look in the ...\adt-bundle-windows-x86_64-20131030\sdk\extras\google\usb_driver directory
Once the driver is installed, open a command prompt and CD to the ...\adt-bundle-windows-x86_64-20131030\sdk\platform-tools directory
Run "adb devices"
You should get a prompt on the N7 asking for permission. Allow it.
You should see your device in the list.
put the SuperSU update file on the N7 by running:
adb push {downloadpath}\UPDATE-SuperSU-v1.80.zip /sdcard/​
if needed, push the OTA file to the same place.
adb push {downloadpath}\{taht awfully long name} /sdcard/​
run adb reboot bootloader
You should be in the bootloader.
Another device driver should install. After that "fastboot devices" should show your device.
Extract the 4.4 factory image to its own directory
Locate the "image-nakasi-krt16s.zip" file in the "nakasi-krt16s" subdirectory.
extract that .zip file to it's own directory
CD to that last directory in the command prompt
run fastboot flash-image system system.img
use the bootloader interface to boot into recovery
Flash the OTA file
Flash the SuperSU update
wipe cache and Dalvik
reboot normally.
In my case, I used TWRP and created a flash queue to flash both the OTA file and SuperSu. When I rebooted, everything came up. The first boot was a little long, and I got the normal post-OTA "Optimizing app n of 200" count.

I just take the OTA, unzip it, edit the update script and remove where it patches boot, recovery-from-boot, power.grouper.so, and in this case, debuggerd. Zip it back up, flash with twrp.

Well, I'm not that up on editing update scripts. Then someone posts the factory image URLs.... That would have been SOOO much faster. That's how I got to 4.3. I used fastboot to flash the 4.3 system image....

./META-INF/com/google/android/updater-script
Remove every line related to power.grouper.so and LNX:5109760 (part partition reference). There's two of each, one apply_check_patch and one apply_patch plus a set_metadata for the power.grouper.so
I could put the file on Dropbox but I think it's more useful to see what's going on than just handing it out. As they say, give a man a fish and you'll feed him for a day. Teach a man to fish and he'll sit out in a boat drinking beer all day.

That's good information. I know last time someone posted details exactly what lines in updater-script needs to be removed (i believe it was 4.3 OTA update). it would be wonderful if someone posts an updated updater-script here, so avoid any kind of other issues.
looking forward to see updater-script attached here!
bunch of thanks!!

small correction on command: run fastboot flash system system.img
in my case, I had to flash boot as well (wrong kernel I guess), otherwise TWRP was giving the emmc error, when flashing the OTA "emmc /dev/block/platform/msm_sdcc.1/by-name/boot 71"
I did fastboot flash boot boot.img
and then flashed the OTA in recovery, followed by SuperSU. And everything was back to normal, including xposed framework, which I had disabled prior to starting the OTA flashing.

Easily Apply OTA Update To Rooted Nexus 6

I had a hard time finding this information, so thought I would post a new thread!
After you root your phone, even if using standard recovery, the OTA updates will no longer install. You may get the notifications, but after it reboots to install, you will get a failed notification. Even if you uninstall root. This is because if there is any change to the system image at all, the OTA update will fail.
To install it is actually easy, just requires some legwork. I assume you understand what the bootloader is, and what adb and fastboot tools are since your phone is already rooted. If you used a toolkit, there are plenty of guides on XDA on how to install these tools manually.
Step 1 - Collect Needed Files:
Visit the Google System Images page and download the image for your existing ROM. Check your About Device page to get the exact ID, it should say something like LVY48E.
Extract the system.img file so you can flash it later.
Download the OTA image. All OTA images are listed on the Nexus 6 OTA Images thread. Find the file which upgrades "From" your current ROM id. It will only work if from matches your current image version. It will be named something like 2bef78c4a5ec8dbaa3df9d94e78af8622cd2a394.signed-shamu-LVY48F-from-LVY48E.2bef78c4.zip, and this file in particular flashes to the new LVY48F version from LVY48E version.
Step 2 - Flash Stock System Image:
This step replaces your system image with the stock system image. This will not delete your apps or other personal data, only the information stored on the system partition. The only exception is if you rooted and stored any data on this partition. Plug your phone into your computer. There is no way to do this without a PC.
Reboot into bootloader mode either from booting with POWER+VOLDOWN or via adb:
Code:
adb reboot bootloader
and flash the image
Code:
fastboot erase system
fastboot flash system system.img
At this point your system is stock again (unrooted).
Step 3 - Flash Update Image:
Enter the recovery mode. You can also do this via TWRP but I will cover with stock recovery. Press Volume Up/Down until you see RECOVERY and press power to choose. You are now in recovery.
Press and hold Power and tap Volume Up once to get the recovery menu. Then use Volume Up/Down to select "apply update from ADB" and then Power to select
I had to unplug and plug my phone back in at this point to get it to show up to adb. You can confirm it is visible with the command adb devices.
Apply the OTA update file using the following command, replacing the file name with your own:
Code:
adb sideload 2bef78c4a5ec8dbaa3df9d94e78af8622cd2a394.signed-shamu-LVY48F-from-LVY48E.2bef78c4.zip
After a few minutes the sideload will complete, the phone will reboot and optimize apps, and you can verify the update worked by checking your about system page again.
To root your device again, re-install SuperSU and you're good to go.

I actually just asked about this in the T-Mobile thread, but thanks for making this. My question is, when installing system.img is there anything else you NEED to flash as well, specifically boot and/or cache?
Google has the latest stock image for T-Mobile so I was planning on flashing system and radio, but I wasn't sure if there was anything else required when flashing system.img.
I know I don't want recovery or userdata as that would replace TWRP and all my data, so I'd of course leave those out.

Nope, system.img was all that I flashed, verified it worked fine with just that.

So you just have to re-root after right?

Thanks for this guide. I've been trying to figure out how to do this exact thing. When I do the command:
adb sideload 4458964f84d2e44ecd2c1c31c301d47eec4b080e.signed-shamu-LMY48M-from-LMY48I.4458964f

Thanks for the guide. Does it wipe all the data and files in internal storage?

I did this successfully

I wanted to say thanks first of all for putting this up. It helps those rooted users out there that do actually want security patches applied to the system image. To answer the question above, No it does not wipe data or storage if you follow the instructions to only modify /system partition.
A note about the LMY48M update file and the above comments in the OP : This update changes the kernel (in other words), the boot.img file as well. So if you have flashed a non-stock kernel, you will need to go back to stock during the update (and I suggest just leaving it). That is the partition called boot where boot.img lives. It mainly is the kernel. The way to go back to stock (say if you flashed franco with the FKupdate tool and did not do it manually) is to simply do like above and flash it from the factory image he mentions above for 48I file.
You reboot to the bootloader (*I assume you know how*) with power and vol down button. And then the following command after flashing system.img:
fastboot flash boot boot.img
This takes you to stock LMY48I and should allow you to update now to 48M. I learned this by watching the update failure messages as well as noticed it has boot.img changed in the zip file. Hope this helps others. :good:

Open the update .zip file and go to META_INF > COM > GOOGLE > ANDROID. You will find the "updater-script" file.
Open that file using a text editor like notepad or notepad++ and delete the following text; starting from "assert ....... till the semicolon of the last getprop command.
Place that file back into the update .zip file and reflash. This should remove the status 7 error.

By flashing just the current system image your data stays in tact. Then you can take the OTA, it will see the system image unmodified, and it will update everything for that new version without wiping data.

Easier to just flash the new system image that gets you to the same place as the OTA.

I was wondering this same exact thing, but I was assuming it was because the OTA was hitting people before that matching Google Factory Image was available. This would bring you almost back a version (to being stock) so you could take the OTA.
If the OTA is to match the same Factory Image you can get from Google, I have no idea why you'd do both steps.

Hi, I have the LNX07M, and I don't find it in the google page. Can you help me? please!

I think the only reason to do both steps is to apply the update ASAP. If you are ok waiting, then only flash the new system.img. That's definitely what I always do. I don't mind waiting. I have Google Play Services notifications hidden now anyway, so those update notifications don't show up and bug me.
Thanks for the walk through though, @bitpushr, I'm sure many can make use of it.

Honestly, you shouldn't edit those files as that can be dangerous, and disabling the filesystem check can be dangerous, and it probably won't work because then the zip would fail signing verification.
If you followed all of the instructions in OP and still get error 7, try, on top of erasing and flashing the stock system.img, also extract and erase then flash boot.img and recovery.img. You will get error 7 if your recovery and kernel (boot.img) aren't stock.

[ GUIDE ] [ Marshmallow Firmware Upgrade ROM install including ViperOneM9 4.x.x ]

Dummy friendly guide how to upgrade, flash and install the latest Marshmallow Firmware and the latest ROM’s such as the ViperOne ROM 4.x.x, this guide is intended for those who are already slightly familiar with the flashing process and have previously managed to flash a ROM on their HTC One M9 device…
CHECKLIST BEFORE STARTING:
1) Phone is S-OFF
2) Unlocked Bootloader
3) Rooted
4) Latest TWRP recovery
5) SUPER CID changed to 11111111
6) External SD Card
7) NANDROID Backup and any or every other form of backup
8) Device drivers, Android SDK Platform Tools including ADB & FASTBOOT.
9) USB Debugging enabled.
10) BACK UP OF ALL YOUR DATA !!!
Before we begin make sure you back up all your data on both the internal and external SD card.
For the purpose of this tutorial we will be installing the latest ViperOneM9 ROM…
a) Downloaded and place the latest ViperOne ROM - ViperOneM9_4.x.x.zip on your External SD card,
Main Thread by j to the 4n is found here:
http://forum.xda-developers.com/one-m9/development/rom-viperonem9-1-0-0-tweaks-hub-t3072773
Latest ViperOne ROM for download is here:
http://venomroms.com/htc-one-m9/
b) If you are currently on ViperOneM9 3.5.0 or older and wish to upgrade to the latest 4.x.x than the latest Marshmallow firmware is required (3.35.401.12 or 3.35.617.12 firmware)… This can be found here and within Sneakyghost original thread.
https://docs.google.com/spreadsheets/d/1ZaiJ3F_f76sVa4daU5H62OYi5Bj23LEBBv4xDTQ8y-M/pubhtml
http://forum.xda-developers.com/one-m9/development/firmware-t3068243
Now download the latest version of either:
NO WIPE ZIP
or
FULL STOCK WIPE ZIP
For this tutorial we will use the FULL STOCK WIPE ZIP (to archive a clean install – this will wipe everything on your phone excluding the External SD card)
c) Place the downloaded M9_3.35.401.12_FullStock_wipe.zip into your Android SDK Platform Tools Folder (for example C:\Android\ if this is where all your tools are found)
d) Download the latest version of TWRP recovery from
http://www.teamw.in/devices/htconem9.html
Place the downloaded twrp-2.8.7.0-hima.img in your Android SDK Platform Tools Folder
e) Once you are 101% ready to begin the process start by connecting your device and launching the command window (hold shift, right click in window with all the required ADB/FASTBOOT aps and select "open command window here) once the black terminal window appears start by typing in
adb devices
if your phone appears in the list we can continue by typing:
adb reboot download
wait a few seconds for the screen to appear and type:
fastboot oem rebootRUU
your phone should now be in the RUU mode with a silver HTC logo, now type
(if you renamed the original file type its current name, by default it is as follows)
fastboot flash zip M9_3.35.401.12_FullStock_wipe.zip
f) you will most likely receive something like this towards the end after running the above command...
FAIL90 hboot pre-update! please flush image again immediate
FAILED (remote: FAIL90 hboot pre-update! please flush image again immediate)
For "hboot-preupdate" response, restart the same procedure for device...
just type the above command again and phone will flash the update again and hopefully it will take at least a minute or more to complete, hopefully there will be no more errors, just in case repeat the above command... Just in case you do see errors try looking them on Sneakyghost's thread found here
g) Once this is done and everything passed than we have successfully upgraded our firmware to Marshmallow... Since we selected the FULL STOCK WIPE option we need to flash TWRP once again (as it was wiped) and don't bother resetting or hoping for the phone to boot normally as it won’t...
(if you renamed the original file type its current name, by default it is as follows)
Type:
fastboot flash recovery twrp-2.8.7.0-hima.img
and once it’s done
adb reboot-bootloader
*if for any reason you need to reset your phone and gain access to the bootloader menu, download mode, recovery etc. you can always do this manually by holding vol up, vol down and power buttons at the same time for a few seconds to reset the device, to get into the bootloader, recovery, download mode etc. After the phone resets continue holding the vol down and power button until you reach the bootloader menu.
*if you type adb devices and you see multiple devices or emulators that prevent the commands from working I suggest running the following:
adb kill-server
adb devices
Now only your connected device should appear…
h) It is now time to enter our recently flashed recovery to finally install our latest ROM.
Enter the recovery manually or by typing
adb reboot recovery
From there you may select the wipe option (swipe to factory Reset) and proceed to the Install section, browse for your ROM file and select it.
i) Within Aroma installer select all your preferred options and begin to install, once the flashing completes your device should reboot and now you keep your fingers crossed and wait (will take several minutes so just be patient…. And DONE!!! You now have the latest Marshmallow firmware and ViperOneM9 ROM installed.
#Please note that I’m no expert when it comes to these matters, this guide is here to help anyone who is unsure what to do, I tried to write it up the best way possible (sorry that there are no fancy pictures) if there any errors or issues with my methods please feel free to correct them but so far they worked for me and hopefully will also work for you. (This guide will also help you flash other ROM's) If you need more help please feel free to ask, there is always someone here on xda who knows the answers 

Excellent write up !!
Many thanks !!!....g

Very nice writeup. Just got an M9 for the wife. I've been around the block so I get everything, but I've been away from HTC since the One X...well, there's the N9 but it's a nexus. What are the RUU mode and Download mode. If I remember correctly there was only the bootloader to go to on the One X. If it's complicated is there somewhere I can read about the modes?

Can you write instructions for s-on and unlocked boatloader? Thanks.

Excellent write-up! For extra-completeness, could you please cover changing the mid in android-info and dealing with error 22 (stuff about headers). I'm still fighting that one...
Thanks for your time.

Have you received the official Marshmallow OTA yet on your device? the S-OFF method is available for those who don't want to wait for official updates, I will gladly write up a S-ON method once more people receive the official update...

Also try the following as error 22 was not covered in the error handling section...
http://forum.xda-developers.com/showpost.php?p=59783531&postcount=3
Download 7zip, open the zip inside of the program, right click on the Android text file and open within. Change the mid to yours hit save. It will ask if you want to update the zip, hit yes. Then try and flash.
SneakyGhosts post explains this:
Error 22 is new to me too but the string is kind of self explanatory: every archive has a header where the archive-program finds info about what type of archive and what compression. If the error says anything about this header, the logical conclusion is either a corrupted, broken archive or an unsupported archive type.
I suspect the latter simply due to the fact that the zip was unpacked and repacked, which then easily creates an incompatible zip.

because you need the latest firmware in order to install 4.x.x and the only way to get the latest firmware is via the OTA or by flashing it with the s-off method.

I'm still kind of "fuzzy" on this whole firmware thing.... IF I don't want to wait (on ATT) and IF I go S-OFF, which firmware can I/should I use for Marshmallow?

Delete

HI, can you please tel me how long does the firmware flash take as mine has been at it for over 2 hours? Not sure if it is stuck?

I am on sprint. How do i get the new firmware? It isnt on the list. Thank you

After OTA 3.0 update, TWRP screen shows up after reboot?

So, I just downloaded the OTA 3.0 update and it said to reboot to continue? So, I let it reboot but after rebooting, it loaded up the TWRP screen?
What should I do?

Navigate to /data/user/0/com.nvidia.ota/app_download
There should be your downloaded ota zip and install manually through twrp. If that would be native stock recovery the process of installation would be automatic

Thank you! But, my machine doesn't have a subfolder called, "0" after /data/user/?

Follow the guide i provided below my text. I merely ran through the process, but roughly followed the guide mentioned. Also, What I did was a clean install method
I dont know about visitor29's post, as I didn't go that route. But for me personally, I clean installed the previous 2.1 update, by connecting to my pc, rebooting into fastboot, then sending fastboot commands to flash the images for 2.1. once this reverted back the recovery image to stock. once finished i booted back into shield and allowed it to update, which, with the proper recovery installed, managed to update to 3.0. i then did a factory reset (just to be sure everything was fresh. thats usually how i do major version updates, personally). After that, I went back into fastboot, BOOTED twrp (not flashed recovery) and installed the supersu.zip i previously put on the shield when i did the 3.0 refresh.
Sorry this is just a quick dirty rundown on what i did. Make sure to follow proper steps provided here:

I just started looking in all the folders and found the ota.zip file. Mine was located in:
Code:
/data/data/com.nvidia.ota/cache/
However, I have a new problem now. I keep getting this error:
Code:
This package is for "foster" devices; this is a "shieldtablet"
E:Error executing updater library in zip '@/cache/recovery/block.map'
E:Error installing zip file '@/cache/recovery/block.map'
I don't want to do a stock reset because that means I'll have to reinstall Kodi again. I don't want to lose all my preferences and settings in Kodi.

(little bit browsing for appropriate folder then walk through factory reset procedure for automatic upgrade ??? !!!!) yes u can do that if you already on 2.1, but if you on 3.0 vulkan without stock recovery? and my way bit faster is (just navigate to appropriate folder for ota) ---- after upgrading 3.0 you can do factory reset through twrp or through system it self.
