I think you must backup the stock 4.3, add rom from backup, then install ota on it .
[Nexus 7 General] langhaardack:
I just found out you need the original kernel to install the OTA, too.. ^^
[Nexus 7 General] mimox:
Whenever I run into issues with OTAs I just install the latest factory image, then the OTA will work.
[Nexus 7 General] GeorgesAbitbol:
The second try from adb sideload with cwm was the good one.
[Nexus 7 General] Erroneus:
Heads up for anyone else having this problem.

I managed to fix it, by deleting /system/xbin/daemonsu and /system/bin/.ext/.su , so maybe the OTA update has an issue with SuperSU v1.69?

Went into recovery, mounted system, connected my Nexus 7 to my PC and from CMD on my PC:

adb shell

cd /system/xbin/

chattr -i daemonsu

rm daemonsu

cd /system/bin/.ext/

chattr -i .su

rm .su
[Nexus 7 General] osm0sis:
Yes. You always need stock kernel and whatever radio came with the build you're upgrading from. Since this is a big update you should also undo any mods to system files you've made.

If you can't undo then either extract the files you need from the JB4.3 Factory Image system.img or flash the whole image to be sure.

Pretty sure those with issues are using an older version of SuperSU that locks files, preventing the OTA. Make sure you're on the newest by flashing it in recovery and you should be fine. Same might go for Superuser, but I'm not sure about the install process there.
[Nexus 7 General] langhaardack:
I just went with fastboot flashing the factory system.img, boot.img and to be 100% sure i even flashed the bootloader again. ^^
[Nexus 7 General] nikola1970:
Can i update this via adb sideload if i have 4.3 rooted and unlocked bootloader? I got some error when i tried updating, and update is aborted.

Also i have Xposed on my Nexus 7.
[Nexus 7 General] osm0sis:
Xposed is a system file mod. What did I just say in my last post?
[Nexus 7 General] Erroneus:
I was running a stock rom, with stock radio and with the latest version of SuperSU; v1.69. But I still had the problems as I described, which was fixed by removing deamonsu and .su and nothing else. It might be some leftover from an older version of SuperSU, but I didn't have these problems when updating to eg. 4.3 (JWR66Y).

But I managed to fix it, so no big problem, hopefully other can use my mini-guide, if they run into the same problem :)

** Update **

My problem, might have been caused by "Survival mode" in SuperSU. You learn something new each day :)
[Nexus 7 General] nikola1970:
Alright, uninstalled Xposed and tried once again, same error:

"Error in /tmp/update.zip

(Status 7)

Installation aborted"

Any help?

I just updated my 2012 Nexus 7 by side loading the Kit Kat 4.4 without a hitch. I even had the boot loader locked.
[Nexus 7 General] RealCaracas:
Hi! I just instaled the KiKat!!...

1) Complete Wipe in Bootloader

2) Installed Stock image JWR66Y (https://developers.google.com/android/nexus/images#mantarayjwr66y) with fastboot

3) Went again to Bootloader and installed TWRP

4) Boot Recovery

5) Flashed KRT16O (http://android.clients.google.com/p...signed-nakasi-KRT16O-from-JWR66Y.13088e35.zip) in TWRP

6) Reboot System / Install SuperSu when Promped

7) Nexus 7 with 4.4 like out of the box
[Nexus 7 General] langhaardack:
stock kernel?

fastboot flash system.img, and boot.img from 4.3 factory image and it'll work fine. I just did so after accidentally flashing franco on 4.4 xD But the 4.4 kernel works with cm 10.2 at least, if you like multibooting to cm10.2 ^^
[Nexus 7 General] h0meal0ne:
kit kat kernel version

Install kit kat update. Why kernel version 3.1.10??? I think kernel must have 3.4 version.
[Nexus 7 General] jrdiver:
My nexus 7 2012 is not letting me update... :( i checked the md5 and they match and it just says:

Error executing updater binary in zip

Error Flashing Zip

Updating partition Details...

and in big red letters in TWRP "FAILED"

It still boots into 4.3 though and i tried a full unroot also without any results

EDIT: Also i would like to not lose everything and reflash 4.3 if i can help it. i had the franco kernel on it but already reverted that back to stock. im out of ideas.
[Nexus 7 General] jphilippon:
Can I use the 4.4 file to come from any ROM or does it have to be coming from 4.3?

(i'm trying to get my GF's N7 off of CM and on to stock 4.4 without a toolkit or computer. Just USB OTG and flashing thru recovery.

EDIT: Found an ODEX 4.3 JWR66Y and I'll flash that THEN the 4.4 update.
[Nexus 7 General] Miso_Ramen:
Having trouble installing it. :( I just came from a custom kernel so I flashed the stock kernel before I tried updating. Here's what it says:

"/system/vendor/lib/hw/power.grouper.so" has unexpected contents.

E:Error executing updater binary in zip 'data/media/0/sideload.zip'

Tried updating through ADB sideload and TWRP but it still fails.

Stock ROM, stock kernel, rooted, TWRP, md5 matches
[Nexus 7 General] oldblue910:
Only on the Nexus 5. Kernels are device-specific, so usually the kernel never gets updated to newer major releases.
[Nexus 7 General] delphi.actual:
CWM can flash kitkat TWRP cannot at this time

for those having problems flashing with twrp update to cwm 6.0.4.3 which can flash kitkat
[Nexus 7 General] osm0sis:
Also make sure you read the full error message, it will always tell you where it went wrong. Just saying "Status 7" means nothing. If it tells you a filepath, go look at that file and see if whatever modded it left a backup of the original.
[Nexus 7 General] RainGater:
I was in AOSP 4.4. Here is how I updated to the official 4.4:

IMPORTANT: Backup your current ROM from TWRP

1. Copied the 4.4 OTA (renamed it to update44.zip) to /mnt/sdcard: adb push update44.zip /mnt/sdcard/

Also, copied UPDATE-SuperSU-v1.65.zip to /mnt/sdcard

2. Downloaded 4.3 factory image from https://dl.google.com/dl/android/aosp/nakasi-jwr66y-factory-1e503532.tgz and extracted the system.img and boot.img

3. fastboot reboot bootloader

4. fastboot flash system system.img

5. fastboot flash boot boot.img

6. Reboot to Recovery (TWRP is what I had)

7. Install update44.zip and optionally, UPDATE-SuperSU-v1.65.zip (who wouldn't want to root)

8. Did a factory reset - First tried by just wiping cache/dalvik and had a boot loop

9. Reboot system and voila, 4.4 it is!
[Nexus 7 General] Miso_Ramen:
Tried that. Still didn't work. As much as possible I want to avoid wiping my N7.
[Nexus 7 General] osm0sis:
Come with me if you want to live.

No, but seriously, read the post I made an hour ago, it was directed at you. You have a filepath there. Go look in that path and see if there's a backup of the original power.grouper.so file. Can't boot? adb shell or adb push the AROMA Filemanager zip. It's invaluable.

And to everyone else, if you don't want to wipe start posting more detailed reports of what's happening. Give me the exact errors like Miso did, and I or someone else here should be able to talk you through it.

I also prefer to help people who want to read and learn. ;)
[Nexus 7 General] jordandalley:
If you want the new launcher you'll need to install this manually by installing these two APK's:

https://drive.google.com/a/dalleyfamily.net/#folders/0B-D78F7kekqzbkt2endTXzQxakE

I stole them out of the Nexus 5 and Nexus 7 (2013) OTA's. Works well for me and shows background images fading through the screen buttons etc.
[Nexus 7 General] osm0sis:
Yup, I've got those up on my Dev-Host as well as the required /system/lib/ dependencies:

http://d-h.st/users/osm0sis/krt26m-kk4_4-apk/

Cheers! :)
[Nexus 7 General] bjorn60:
Thanks for posting the update for the 2012 N7. I've tried installing but keep getting an error about how the update is for grouper and the device is tilapia. I've checked everywhere in my build.prop and it all shows as grouper. Does anyone have an idea if I'm missing a file location that's telling the updater script that I have a tilapia device?
[Nexus 7 General] osm0sis:
I've heard of the opposite when someone's using the wrong recovery version, eg. CWM grouper on a tilapia. Maybe make sure you've got the correct recovery? Follow the grouper link in my sig for my CWM thread.
[Nexus 7 General] EAK128:
For me it gives an error about the boot animation.zip

/system/media/bootanimation.zip has unexpected contents

I know I haven't touched it, but to make sure I got a copy of the stock one and copied it to same location and made sure permissions are correct, but still get the same message.

Any ideas?
[Nexus 7 General] Miso_Ramen:
Alright, thanks for the help. :) I checked that filepath and power.grouper.so is the only file in the hw folder. I dunno if that's been modified (coz I switched to M-kernel before) and if I should find an unmodified version, or if I should delete it.

My N7's boots up okay. I just want to update to 4.4. :D
[Nexus 7 General] osm0sis:
My only thought is the one you thought was a copy of stock, wasn't.

If you do not have a backup somewhere, then read the second half of the first paragraph here to learn how to extract them from the factory image:

http://xdaforums.com/showpost.php?p=28181832&postcount=2#2

Lots of kernels modify that file. Most backup the original. Sounds like yours didn't. Definitely follow the instructions above and you'll have your KitKat! :)
[Nexus 7 General] bjorn60:
Thanks a ton, it must have been my TWRP recovery I was using. Updated to the CWM in your SIG and now I have kit kat!
[Nexus 7 General] jordandalley:
Sweet! Be nice to package all of it into one APK...
[Nexus 7 General] rhyang:
Here you go.
[Nexus 7 General] st2008:
I updated the TWRP with nexus toolkit and then installed the stock 4.4 zip file with recovery mode. Now I'm running kit kat without erasing anything and my device is still rooted. Yoohoo! The only disappointment with the kit kat is the "new ram management" doesn't increase antutu score.
[Nexus 7 General] nolimit06:
So I did the sideload... it updated to 4.4 but where is the new kit kat boot animation, where are the wallpapers. Absolutely nothing changed except for the version number. Pretty disappointed to say the least. My question is... how come the 4.3 images are over 300mb and the 4.4 is only a hair over 100mb?
[Nexus 7 General] keneth_c:
This release is not for the Nexus 7 2012 (WiFi + Mobile) / nakasig right?

Please confirm.

[Nexus 7 General] oldblue910:
Your bit animation should be the one that's used on Google Play Edition phones. The X animation should be gone. Also add far as the size, you're comparing the 4.3 factory images to the 4.4 OTA file. Unfair comparison.
[Nexus 7 General] Bootyologist:
I'm running stock 4.3, rooted and unlocked. I flashed the update un clockwork and got the status 7 error like a few other users are reporting. When I rebooted, it's showing the KitKat animation, which is strange considering the update aborted. Now it's stuck on the boot animation. Tried rebooting again, and same thing. Tried restoring a backup and it failed. What should I try next?
[Nexus 7 General] EthanFirst:
Thank you

I add to Google Nexus OTA Download page and update Nexus Update Checker app
[Nexus 7 General] oldblue910:
You'll have to flash the 4.3 factory images, wipe data, then update again.
[Nexus 7 General] ShadowOf:
I'm up to date on 4.4 KRT160, coming from 4.3 JWR66Y. Everything went smoothly, didn't get an error or lose a thing. My N7 (2012 Wi-Fi) is rooted, stock kernel, CWM Recovery 6.0.4.3, no system changes.

These are the directions I followed: http://goo.gl/OcEjEc

Enjoy KitKat!
[Nexus 7 General] Bootyologist:
Balls, was hoping to avoid that. Thanks.
[Nexus 7 General] nolimit06:
Thanks for the clarification, I was unaware of the difference. n00b moment for the day :P
[Nexus 7 General] LordPhong:
I don't see how you can go wrong with these instructions. muchos thankos
[Nexus 7 General] osm0sis:
If you read back a few pages and read my posts you can avoid that. You need to start by posting something better than "Status 7" when the recovery tells you much more than that.

That's not how APKs work, and I don't want to do zips where I want people to pick and choose what APKs they want and do it themselves.
[Nexus 7 General] ogre_x:
My recovery didn't show a file path only that recursive bla bla failed when it was almost done. I suspect some write protected SuperSU leftover in /system. Didn't boot at all after that so it was back to JWR66Y and fresh ota via sideload.
[Nexus 7 General] EAK128:
Thanks osm0sis, found a stock odex ROM zip and got the boot animation from there and it worked.
[Nexus 7 General] osm0sis:
All you need to do is flash the SuperSU zip before the OTA and it'll disable OTA Survival in case you've already gone too far and can't boot to disable it.

Extracting it from the Factory Image yourself probably would have been faster and better knowledge for the future. ;)
[Nexus 7 General] st2008:
Well not impressed ! The 4.4 prevent Firefox for using flash player! That's not cool :mad: I reinstall both applications and the firefox still can't "see" the flash player ! Many web sites that I visit are still using flash player!

"Don't be evil" was Google's slogan. I really want to know why Google deliberately blocks people for using flash player.
[Nexus 7 General] oldblue910:
Did you ever think that maybe Flash finally lost compatibility with 4.4? Officially Flash has no compatibility past 4.0. It worked on with 4.1 - 4.3, but that was just gravy. Maybe 4.4 finally broke Flash. Time to put your big boy pants on.
[Nexus 7 General] osm0sis:
Flash Player is for Ice Cream Sandwich, "don't be evil" has nothing to do with it.
[Nexus 7 General] ogre_x:
Nah, I'm not sure if it really was SuperSU leftovers or some other stuff I'd done with the /system, so I was better off with a clean slate anyways. Just a bit bummed that the recovery didn't say anything about what was wrong. I had been experimenting with SuperSU when Superuser took some time to get 4.3 daemon mode running. I won't be using it again if I can help it.

Since factory 4.4 isn't out and the OTA already had patched all the files my best bet was to do a fresh install of 4.3 anyway. Otherwise I might have tried fastboot update without -w on the system image zip for 4.4 before starting from scratch.
[Nexus 7 General] osm0sis:
Also worth mentioning again or those who constantly fail to read back in the thread a few pages.. ;)

All you need to flash is system.img AT MOST to meet the OTA requirements, no need to flash userdata.img and lose all your app settings... Then all you'll need to do is reinstall any special system apps and mods you had.

If you're using CWM it definitely tells you what's wrong, TWRP can be a bit cagey but you can access the logs.
[Nexus 7 General] Jpcsilva:

Does 4.4 update wipe system?

Hi,

Sorry if this was answered somewhere.

I have locked bootloader, unrooted (every update installed without problems for far) stock unmodified nexus 7 (2012) with stock 4.3, will the 4.4 update wipe my internal SD or user data, or i can safely click update without making backup?

[Nexus 7 General] Cor-master:
Where is a full rom version?
[Nexus 7 General] jrdiver:
And she lives!!!!! My method was a little different variant on the same thing

1) use the nexus root tools to make a backup (i did everything and then just the apps with their data

2) Nuke everything with the 4.3 installer

3) Reinstall twrp

4) Upgrade to 4.4

5) Restore apps/w data

From here out is still being planned out...still restoring atm

6) Reroot

7) Finish updates/enable the google experience manager

8) Have fun
[Nexus 7 General] chi_heng:
No, this OTA update will not wipe data. if you're going to sideload the file with adb, you may as well perform an adb backup with data, just to be safe. I'm not sure if it's performed after the update, I manually wiped cache with the stock recovery after the procedure ended.

[Nexus 7 General] cy88:
These two guys got the solution to put 4.4 OTA on (and optionally root). I struggled for the whole night and CWM version is the culprit. I am now rocking on 4.4.

Link to CWM Touch 6.0.4.3: http://download2.clockworkmod.com/recoveries/recovery-clockwork-touch-6.0.4.3-grouper.img

To flash:

1) Put your device into fastboot mode

- Shut down the Nexus

- Hold all three button until you see the Android

2) Make sure you have driver and fastboot on your comp, connect the Nexus to your computer

3) type "fastboot flash recovery recovery-clockwork-touch-6.0.4.3-grouper.img" in your fastboot directory if you didn't set path to your android sdk/fastboot

4) Boot into recovery and flash the OTA after completing the steps that RainGater outlined

Enjoy!

[Nexus 7 General] oldblue910:
Hi everyone. As we are all aware, a new variant of the Nexus 7 is coming out which has mobile data. This means it will likely run a firmware variant other than nakasi and will have a device name other than grouper. If anyone plans on buying one of these, I would love if you could check a few things for me before you go flashing ROMs to it or accepting any OTAs. Here's what I'll need from the device:

1. The bootloader version. (Found only on the main bootloader screen)

2. Android version and build # (From settings)

3. Baseband version (From settings)

4. Firmware and device name. To get these two pieces of info, open /system/build.prop in a text editor and post the values of ro.product.name and ro. product.device.

Again, please do this as soon as you power on the device, before applying any OTA that may be available out of the box! Thanks much for your help!
[Nexus 7 General] osm0sis:
JBQ mentioned the 3.41 bootloader changes were for the new hardware revision, maybe he meant the version with mobile data and it could still be grouper? That would be pretty cool. If not, my money's on grouperplus. ;)
[Nexus 7 General] oldblue910:
My money is on blowfish. ;)
[Nexus 7 General] osm0sis:
Hey oldblue, segv11 is looking at system dumps from locked/unlocked 3.41 bootloader to see if there's any way to extend BootUnlocker to support the N7. I was hoping that if you had a bit of time you might be able to contribute dumps as well.

More data on what changes is better, so if anyone else reading this would like to help, please do.

[Nexus 7 General] oldblue910:
Well I don't know how much use I'm going to be because my device isn't rooted. I keep my devices completely stock and unrooted, so in order for me to contribute bootloader or system dumps, I'd have to unlock my bootloader and root, which means setting up my N7 from scratch again. haha If I'm really needed, I might be able to do that this weekend, but I won't have time this week. :D
[Nexus 7 General] osm0sis:
Hmm yeah, unlocking for you would mean wiping, which would mean setting up from scratch. :(

Well we really would appreciate it if you could, or if anyone else you know or reading this would like to save you the trouble, please come help.
