Strange.. An OTA officially into the wild before the source code?? What the heck is going on here?
[Nexus 7 General] TheByteSmasher:
Update issues

If ou are having update issues, 2 things you can fix (if you messed with them in the first place:

if you used the adobe flash fix and changed browser.provider.proxy.odex (stock ROM) to *.odex1, remove the "1"

if you changed your camcorder to 720p and didn't backup your original system/etc/media_profiles.xml, I have attached an original copy. if no other changes were made to your system files you should be good to go!

I'm on a custom Nexus 7 rom "pa_grouper" and my build number is - "4.1.2 JZ054k" can i install the update from the zip or i have to be on complete stock -JZ054K ? .
[Nexus 7 General] TheByteSmasher:
Won't work. Your system files won't match what the update is looking for.

Happened like that for 4.1.2 also.
[Nexus 7 General] oldblue910:
I no longer need item #4, but I do still need #1-3. Has anyone ordered an HSPA+ Nexus 7? If so, could you get that info for me as soon as you turn the thing on, before applying any OTAs? I have reason to believe that, like the Nexus 4 and 10, it doesn't ship with JOP40C out of the box.

Thanks!
[Nexus 7 General] oldblue910:
OK I was able to piece together some more data about the 3G Nexus 7's firmware. It ships with Android 4.2, Build JVP15S. I still don't have the bootloader version that JVP15S ships with. I still need someone to provide that bootloader version (just reboot into the bootloader and it'll be right there on screen) and also get the "JOP40C from JVP15S" OTA URL from logcat. These will both need to be done before updating your device to JOP40C.

If anyone can help, I'd appreciate it!
[Nexus 7 General] oldblue910:
Yes. Out of the box, the 3G Nexus 7 ships with 4.2/JVP15S. There is an OTA you'll get the first time you turn it on that will bring it up to 4.2/JOP40C like all the other devices.

Keep in mind I'm talking about the new 3G/HSPA+ model, not the older WiFi-only model.

Thanks yo. Here's how I installed from 4.3 PA I downloaded [Toolkit] Wug's Nexus Root Toolkit v1.7.5 [Updated 11/08/13 http://xdaforums.com/showthread.php?t=1766475

Changed my model type nexus7 wifi 2012 version, installed using unroot/flash stock 4.2.1 or 4.2.2 I forget which one worked.

Once done, google updated me to JWR66Y 4.3 stock.

Then I downloaded 13088e35942c77e4752aa1fdf51d54472509b941.signed-nakasi-KRT16O-from-JWR66Y.13088e35 Correct version for me.

Using Nexus Root Toolkit I clicked on launch advanced utilities, on the top right flash zip from computer just like in the photo here. Added 13088e35942c77e4752aa1fdf51d54472509b941.signed-nakasi-KRT16O-from-JWR66Y.13088e35 to the list and made sure I had adb/USB debugging on for every flash from developer options. And the installer just did the rest, push, twrp (temp) then flash etc etc.

Very simple. I'm sure there's other methods but this is what I did coming from stock. Sorry if there's holes in this, its not supposed to be a tutorial. I'm sure someone can figure it out from what I mentioned.. :D common sense

Edit, I used the same program to push new Google Home launcher from here http://xdaforums.com/showthread.php?t=2507748 and rooted as well. Now just a simple input of the lib files and permissions and OK GOOGLE will work like a charm.

Thanks again for the links to 4.4!!!

[Nexus 7 General] Primus76:
I finally got it up and running. Following all the previous posts when I encountered problems I was about to give up and what finally worked was using WUG's toolkit and used the ADP sideload button for unlocked devices in advanced menu. Worked perfect.

Funny part, started freaking a bit once it fully booted thinking there was a video glitch with the USB Debug icon in the notification tray. It was all bars instead of the bean. Then the bulb went on realizing THERE ARE 4 LI... BARS... Now to get the launcher and wallpapers.
[Nexus 7 General] bcrawford:
Are you having any trouble with the keyboard popping up when return to the home screen via the home button? Every time I use it, the keyboard pops up with the cursor in the quicksearch bar.
[Nexus 7 General] Primus76:
Same here. Don't know if this is supposed to happen or not. Installed only Velvet and Launcher which seem to work just fine. Top search bar says ok google and responds to me no problem but every time I go to my home screen it opens the keyboard.
[Nexus 7 General] SkyboneNoya:
No problems here, set the permissions correctly. I use root explorer, check the permission of other files in the contained folder and go by that. Maybe check your keyboard version. Also try clear dalvik and cache in recovery and reboot.

Also, it was just in my copy of files but I copied over Prebuiltgmscore.apk ? Lib files are needed as well, which can all be used on 4.3 even to get OK GOOGLE working.

4.4 google keyboard is draining battery on some devices so disable in apps right after you find another keyboard maybe. That's what I had to do on my galaxy s3 with Unofficial 4.4 CM 11. Swift key is nice.

[Nexus 7 General] Ezekial:
Another successful update here. Thanks to all the good discussions.... for me...

1. Started with Nexus 7 - Stock ROM, rooted, TWRP version about 5 months old.

2. Updated to some of the Nexus 5 apps. Search, Play / Play Services, launcher, etc.

3. I backed up my current ROM for good measure and then downloaded the latest SuperSU & OTA update.

4. Ran the install and had errors on executing the post install scripts.

5. Had to restore to my old ROM.

6. I redownloaded the OTA just in case of issues, pushed that over to my Nexus 7. I also grabbed the latest TWRP from 11-05-13. Finally I renamed the long OTA .zip file to a short filename.

7. Flashed TWRP

8. Ran the OTA install, finished perfectly. Flashed SuperSU.

9. Rebooted and up and running just fine. SuperSU app is crashing on me some and G+ crashed once. Also battery life is dropping, but that has always been the case for me on new installs/uprades on all my Android devices. I think this will settle in nicely in a few days. I will try clearning some cache/data on some apps and I think I will be just fine.
[Nexus 7 General] Primus76:
Rebooted after clearing cache/dalvik and still happening. And it works perfectly and reacts to the keyword, it is just weird that the focus goes to the search bar and the keyboard pops up. Went back to the regular launcher and everything is happy. The google experience launcher also changes the screen size as I can't keep my widgets the same way on my home screen.

I assume that the standard ota update process leaves the old launcher as is?
[Nexus 7 General] jauffre:
problems after the update

Hi to all.

Yesterday i downloaded and flashed the 4.4 OTA from this thread, and my nexus 7 booted normally; but today, using the device i noticed a couple of problems:

1) home button is not working (if i press it i can hear the sound response, but it doesn't bring to the home screen);

2) right notification bar won't appear;

3) missing lock screen security (i set the device lock on power button press, but it doesn't work);

4) when i click on web links, it just opens chrome, without going to the web page;

I tried to go back to 4.3, but it caused bootloop, so i decided to stay with this "kitkat taste" until google releases the factory images.

somebody else had the same problems?

i have a stock nexus 7, with unlocked bootloader, and use the CWM recovery (6.0.4.3 not touch).
[Nexus 7 General] SkyboneNoya:
Yeah that is weird. I have not noticed any keyboard popup but try clear the settings of the launcher even if possible. I know you can edit the build.prop to get more screen size but the keyboard.. No clue. OK google takes focus on main screen with the search bar of course for the voice guidance in google now, which you can enable through holding the home screen and clicking settings. I would see what others are experiencing on the forums for those released files. Here

Another note, I had clicked wipe cache/dalvik/data checked and enabled in the Nexus Root Toolkit as shown here before flashing 4.4 Data/cache/dalvik

Or try a factory reset/install it all again. 4.4 Comes with the lib files so only focus on the apps, and make sure they're all updated on google play.
[Nexus 7 General] bcrawford:
Downloaded, installed, and the issue is gone. No more keyboard pop ups! Thanks!
[Nexus 7 General] bugzy:
Finally got the 4.4 update to work.

I was having issue with Bootanimation.zip. Looks like I could get an image to flash down because my bootloader version was old version 4.13. Need to have Bootloader - bootloader-grouper-4.23.img

Manual Update Procedure without any Toolkit use

(stock recovery, no root, locked bootloader)

You must have USB debugging enabled on your Nexus 7. If this is the first time going into developer options on your Nexus 7, just go into “About Tablet” from your settings and tap the build number about seven times. Hit the back key and you will now see all developer options from now on.

Power off your nakasi Nexus 7, and power back on by holding the Volume Up and Volume Down buttons while it boots.

The fastboot menu should appear and you should see “Start” in the top right. Press Volume Up till it changes to “Recovery.” Press the Power button to select it.

You will see an Android with a red exclamation point icon, press Volume Up and the Power button at the same time.

You will get a new menu and you can navigate to “apply update from adb.”

Now it’s time to connect your nakasi Nexus 7 to your computer via a USB cable

Open the command prompt in Windows (cmd in Windows, regular shell in Linux and Mac) and navigate to the directory that the Zip file is located in.

Type: adb sideload 13088e35942c77e4752aa1fdf51d54472509b941.signed-nakasi-KRT16O-from-JWR66Y.13088e35.zip

The update will install and reach 100%.

Reboot and enjoy Android 4.4

[Nexus 7 General] oldblue910:
The nakasig Nexus 7 3G factory images for KitKat KRT16O are now available. This means the OTA is upon us. If anyone out there has a 3G Nexus 7 2012, please grab the OTA filename when you get the OTA.

Sure. Latest version is recommended. I can tell Linux and Mac are a lot easier to set up than Windows. Just extracting. Windows 8 has some detecting issues with nexus devices.

Rarely do the "stock ROM zips" = factory images. Use fastboot and flash system.img and boot.img from the JWR66Y Factory Image, then you should be fine.
[Nexus 7 General] rubber guard:
anyone remember how many days it was last time between nakasi and nakasig?

Normally never more than a few days. Please post the OTA file name in your /cache folder when you get it!

Correct. The most you'll have to do is reinstall busybox and any mods you use. All user apps and data will remain intact.

Nexus 7 (2012) "nakasig" zip

Hey guys

I realized that this thread does not have a link to the flashable zip file for KitKat (Android 4.4) on "nakasig" (Nexus 7 2012 - 3G).

Just seen that the factory images for KitKat on nakasig have been released already.

I haven't checked yet if its available over OTA.... but don't wanna do it either coz i guess i will lose root access.

Not sure if WugsFresh Nexus Root Toolkit is ready to support nakasig with KitKat for rooting.

Awaiting your response / link.

Nobody has posted the filename for the nakasig OTA file yet but as soon as someone does, I'll update the first post.

Updating to 4.4 on nakasig

Thanks a bunch.

Could you or someone also guide me through updating to 4.4 without losing root.

I'm currently rooted with Chainfire's SuperUser (v.165 i believe) and have CWM recovery (Touch recovery - latest build).

I'm really not good with fastboot & adb as such. Hence I use WugFresh's Nexus Root Toolkit.

---------- Post added at 11:21 AM ---------- Previous post was at 11:12 AM ----------

My bootloader is unlocked & has been so since I updated to 4.3 last....

If OTA update is available for me...

could I just do the OTA update...

shouldn't end up losing my data right?

and then root using WugFresh's Nexus Root Toolkit (v1.75 latest) & then install recovery from there?

Sorry for the questions...

It gets a lil confusing at times since I have another android device as well (S3 International),
[Nexus 7 General] dalanik:
Forget toolkits, too complicated.

* get OTA zip, copy to internal memory

* get SU (flashable), copy to internal memory

* reboot in recovery

* install OTA zip

* reboot, it might take a while, just wait until it boots, then let it some time i.e. 10 minutes

* reboot to recovery and flash SU

* reboot

you're OK! :)

This is if you have CUSTOM RECOVERY, you are ROOTED, and you DIDN'T CHANGE anything in the system. i.e. if you have Xposed you need to uninstall it, etc.

Don't be afraid of loosing root, it is so easy to root again! Imortant is that you don't loose DATA! And data backup and restore can take HOURS, compared to root which takes MINUTES :)

Any word on a 4.4 flashable zip? I don't want to do the fastboot/adb method

Sent from my Nexus 4 + 7
[Nexus 7 General] keneth_c:
Ok thanks a bunch. Much appreciated.

I believe I did exactly the same thing the last time.

After I flash the OTA zip & before rebooting system, I have to do a wipe cache and wipe dalvik cache though right?

Also where can I get the flashable SU from?

On the other hand, if System Software updates gives me prompt for upgrading to KitKat... Should I go ahead and do that? I'm guessing doing that I would lose custom recovery also right? If not... Then I can do that & then flash the SU (flashable)?

Much appreciate all the help. You guys are awesome ;)

--
[Nexus 7 General] gsmyth:
Hardly too complicated! :laugh:

Best to try flashing via recovery first as per your post above but if it failed like mine did for some unknown reason, then a toolkit can be very easy and quick. I ended up using Wug's toolkit to flash the system, kernel and bootloader, also did a back up of apps as well, with no problems at all.
[Nexus 7 General] keneth_c:
Not sure what Xposed is? Kernel or something?

[Nexus 7 General] gsmyth:
You can find flashable zip of Super SU below.

http://download.chainfire.eu/supersu

Xposed is a framework thats installed/flashed to modify your ROM (themes, tweaks, etc). If you dont know what it is then you probably wont have it installed.

[Nexus 7 General] jb0ne:
When flashing the OTA through TWRP, I keep getting "unexpected contents" for /system/bin/debuggerd -- despite that I have downloaded the JWR66Y debuggerd and while in TWRP replaced /system/bin/debuggerd with it, and set owner/perms to match the previous one. Same error.

Any ideas? I even edited the updater-script to not check or patch debuggerd - then it got same error on /system/media/bootanimation.zip

I'm running the androguide.fr AOSP JWR66V that has been OTA'd to JWR66Y. I guess I need to wait for a full ROM....I'm worried if I flash the google Official system image I'll lose all my apps and user data.

--------

Edit: I just took the checks and the patches out for both files, got through patching then failed with "set_metadata_recursive: some changes failed. Error executing update binary in zip [etc]". I notice that the patch to build.prop takes place after the set_metadata so that didn't take place. And now when I reboot I just go straight to recovery.

Is there some way to use the downloaded Google 4.4 image and update only system and apps from that file, preserving my current system?

Or maybe I'll just restore my backup 4.3 and use those Windows programs to mount the .img files from factory JWR66Y and get debuggerd and bootanimation.zip out and try again. But I did that with a debuggerd I found in this thread and it still errored out...

What if I download the 4.4 image, extract, get into bootloader, then ONLY run

fastboot -w update image-nakasi-KRT16O.zip

What would happen?
[Nexus 7 General] gsmyth:
Use a toolkit or adb fastboot to flash system.img and boot.img files extracted from the 4.4 grouper factory images. I also flashed the bootloader while I was at it. Really simple and you won't lose any data. With wugs tool kit you can even back up your apps or even make a nandroid if you want.
[Nexus 7 General] jb0ne:
So after exrtacting the img files and rebooting into bootloader I'd

fastboot flash system system.img

fastboot flash boot boot.img

Right? Damn that seems easy...
[Nexus 7 General] wazowpt:
after i download the file i want what do i have to do?

Im in stock rom without root but i dont want to lose any games or files?
[Nexus 7 General] gsmyth:
I did it using Wug's toolkit which is basically the same thing but those commands are executed by the toolkit program after selecting the img file to flash, but yes its as simple as that. It bootlooped on me after flashing the system file (as the program reboots the nexus), but I just entered recovery with volume down and power buttons, flashed the kernel through the toolkit and it was sorted.
[Nexus 7 General] Alta1r:
I've updated my Nexus 7 (3G) manually with the official system image without losing any data. Used fastboot.

I did the following:

- flashed the bootloader --> fastboot flash bootloader XXXX.img

- reboot into bootloader

- flashed the modem (not needed for wifi versions) --> fastboot flash radio XXXX.img

- reboot into bootloader

- removed userdata.img from the zip file (I'm not sure what it is needed for, but thought i might lose data by flashing this).

- flashed the zip folder --> fastboot update image-nakasig-krt16o.zip (my zip was called nakasig as it's the 3G version)

This way will not erase any data from your tablet.

The '-w' in 'fastboot -w update ....' is the command to wipe your tablet, so wouldn't include that in the entry.
[Nexus 7 General] keneth_c:
Hey there

Where did you get the nakasig 4.4 OTA zip file from? It's still not available on this thread.

Are you sure it's nakasig? That's the Nexus 7 (2012 or 1st gen) 3G/Mobile version right?

Mind sharing the OTA zip?

[Nexus 7 General] Alta1r:
All the stock 4.4 images have been released by Google for our Nexus 7: https://developers.google.com/android/nexus/images

Don't flash the package as it is since it will wipe your data from the tablet. See my previous post.

It's not the OTA zip, so you will have to use fastboot to flash it. Your bootloader should be unlocked to do this. Unlocking the bootloader will wipe all the data (data partition and sd card) from your tablet, but since you want to flash the OTA zip I guess your are already unlocked.

Hi there

Yes I did see the factory images that were released by Google on their dev site.

Was hoping you would have the OTA zip file as I am a n00b with regards to these fastboot and adb commands. Wouldn't even know where to start with these commands. Wouldn't know what tools to use.

Hence I use WugFresh's Nexus ROM Toolkit to do most of the work. Lol.

My device (nakasig) is on stock ROM 4.3 and stock kernel as well. Bootloader has been unlocked since I upgraded to 4.3 the last time (learnt my lesson to keep my Bootloader unlocked at all times the hard way... Lol!)

I think I'll just wait on the OTA zip file to come by... *sigh*

[Nexus 7 General] Alta1r:
You could use the toolkit to flash those files i believe (in Advanced settings). You would have to download the factory image and extract the necessary files though.
