Man I got the same problem. What the frack is up with this Google!!!!! Arrrrrggggg

Trying the procedure above now to see it I can save my data. Sigh

 

[xzb6np]

That went well. Not it just sits on the Google screen when you first turn it on and goes no where. Any ideas?

 

[xzb6np]

Isn't powerbutton + upvol supposed to do something? It doesn't now. I can only do downvol and trying to boot to recovery from then menu goes nowhere.

OK, I fixed mine without losing any data by following the instructions below, copied from here.
EDIT: To clarify, I have a 2012 wifi so used JWR66Y factory image and then used ADB sideload to install the kitkat zip update which I found on this page. link

I was in the same situation and ran into that issue as well. What I did was download the 4.3 factory image from here: https://developers.google.com/androi...s/images?hl=vi

Make sure you get the correct one for your device. I have a 2013 wifi so I chose: Android 4.3 (JSS15R)

Inside that downloaded file, you'll find image-razor-jss15r.zip. It's a couple of levels down. Unzip the files from there to your SDK folder (should be boot.img, recovery.img, system.img, userdata.img, and cache.img).

Boot your Nexus 7 to the bootloader (volume down + power) and connect to your PC with USB cable. Do NOT go into Recovery mode yet.

From the command prompt, make sure you can see your device: fastboot devices

Then, run the following commands:

fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system
fastboot flash system system.img

At this point you have a clean install of 4.3 JSS15R.

Now go to Recovery mode and sideload the 4.4 OTA as you originally tried and it should work this time.

I followed these steps and was able to update to 4.4 without losing any data. YMMV

Seriously, thanks for posting this! Worked for me and didn't have to wipe data! Saved me a ton of headaches.

If your tablet is on, power it off.
Press and hold Power until the device powers on, then immediately press and hold Volume Down (while still pressing Power). You will see the word Start with an arrow drawn around it.
Press Volume Down twice to designate Recovery mode.
Press Power to restart into Recovery mode. You will see an image of an Android robot with a red exclamation mark.
While holding down Power, press Volume Up.
Use the volume keys to scroll to "wipe data/factory reset" and press Power to select it.
Scroll down to "Yes - erase all user data" and press Power to select it.
I did this and it worked for me but you lose everything. Still better than a bricked nexus 7.

I am having the same problem. Tried every single troubleshooting step mentioned here and nothing works. The tablet (Nexus 7 2012) always goes back to the Android with an exclamation point and "no command". Not sure, but I think the problem might be, that my Nexus is not unlocked and USB Debugging not enabled. Any idea how to fix the issue anyways? Contacted Google support, no help there

 

[k-ha]

Thank you for these useful instructions!
I accidentally started with the 4.4 image instead of 4.3 and it seems to work also...

 

[seeking]

And I'm another "no command" nexus 7 4.4 update victim. Surely Google must post an answer soon?????
Will I get an automatic email when others post answers or Google does?
Thanks for help. I'm new to Android and Nexus 7 (original)

 

[jmkasperek]

[jmkasperek]

Fixed the bricked Nexus 7 2012 and took it to 4.4. Thank you.

Same problem - Circles and not booting up after system update to 4.4

 

[MTP AVI]

Have the same problem and it wont even switch off - Waiting for battery to drain off and see if it then comes on

Dude!! Thanks for this info. I was able to go back to JB 4.3 and apply the sideload. Initially I thought it didn't work because it stayed a long time in the merging circles. But after enough time it started to optimize all my apps.
Also, on another note "adb devices" was not working right before the sideload procedure. I followed this link exactly as described and I was able to install the driver in my pc and complete the procedure: Fixing adb "Device not found" with Nexus 7/Android devices in Recovery Mode. Good luck everyone rescuing your devices.

Thank you, stock 4.3 nexus 4 OTA update today 'No Command'. This process worked for me and I'm back in business with no data loss. Thanks again!

My Nexus 7 (FHD) took the 4.4 OTA just fine, so I was lulled into a false sense of security when it came time to do my phone...

Do I have to unlock bootloader for this? If I have to then I will lose all my data right? (Bootloader currently locked) Nexus 10 btw.

I want to share how I fixed my "no command" bootloop.
I had a rooted nexus 7 2012 wifi with android 4.3 (JWR66Y) and when I decided to install the OTA update I got stuck on the no command bootloop.

I used the Google Nexus 7 TOOLKIT (SkipSoft Android ToolKit). You can find out more on xda: [Google Nexus 7 TOOLKIT V5.0.0] Drivers, Backup, Unlock, Root, Recovery, Flash + MORE - xda-developers

1.Download & install it
2.Select your device & choose the correct android build you are running
3.Select "Download, Extract + Flash Google Factory Stock Rom"
4.Select to download the google factory image or choose an existing image that you have. I downloaded the 4.4.0 (KRT160) build
5.Boot into Fastboot mode (turn tablet off, keep holding the volume up & volume down buttons and press the Power button, connect to PC via usb)
6.Choose to flash the google stock image you downloaded & when prompted say "NO" to erasing your internal storage data.

When it is finished your nexus will boot into Android 4.4 KitKat with all your apps+data intact
I hope this will help someone!
