I have a Nexus 7 2012 version since 2014, after many updates and installing apps it was becoming slowly and unusable, so I dicided to flash and install Cyanogenmod 12.1, after installing it, all was fast and smooth, I loved it, but after a month it was turning laggy again, so I decided to use Nexus Root Toolkit to come back to 4.4.4 stock. After flashing, the tablet still in recovery mode, I selected START using the buttons, and the Google logo appeared but a little message in the corner of the screen scared me, it said "booting failed" , so I tried to flash again, but now using the option "the tablet is bricked/bootloop" but it didn't work, so I tried to turn off the tablet and power in again, but nothing happened when I tried to turn on again, the tablet didn't turned on and now it still off, when I plug the charger the battery logo doesn't appear and tried to press the power button for 30 seconds without success, I need help guys, someone told me that it will be possible to fix it, but he doesn't know how to do it.
Thanks for your attention!
Hello,
please charge you Nexus 7 (2012) 2 hours and then try to boot into Fastboot-Mode!
Try holding power button and volume down until the Google logo shows up
I fixed my nexus 7 doing that when it wouldn't turn on

About a year ago, I decided to try the 5.0 release. Upon installation and reboot, It stuck at the "Google" logo. I was able to get into the bootloader, and it said it was still unlocked, but I couldn't do anything: boot to system failed, and even boot to recovery failed. Formatting/deleting the various partitions failed (cache partition was corrupt but couldn't be formatted); flashing a bootloader from the latest Google images didn't help.
I fixed it by buying a used motherboard from eBay for $30. It was fine with 4.4.4/f2fs for about three months, but when I once again upgraded to 5.0, the *exact same* thing happened.
I now have yet another motherboard and will not ever upgrade past KitKat.

Hello everyone, I'm new in this forum and have just bricked my Nexus 7 .
I was not very happy with my Nexus 7 with JB version 4.2.1, it lagged and took long time to load apps etc. I used the Nexus 7 toolkit to unlock my bootloader, flash recovery and then tried a few custom roms. I eventually flash the official 4.1.2 firmware from google but the constant notification for firmware update annoyed me and I decided to root and get rid of the firmware update notifications by installing fotakill.apk.
But when I tried to root using the Nexus 7 toolkit, I chose the option to sideload the zip files for rooting automatically. It asked to flash my boot loader to a lower version (3.34, mine was 3.41) and afterwards it rebooted the device and eventually got stuck at a screen with these lines:
now send the package you want to apply
to the device with adb sideload <filename>
after a long time without anything happening, I suspected that things went wrong and pressed the power button for a few seconds and the device turned off. Now I cannot turn it back on, when plugged in it doesn't show the charging battery, also I cannot boot into fastboot mode by holding Volume down + Power button. The screen stays black the whole time.
I even tried to open the back power and pull the battery out and in again and try to turn on the tablet, nothing happens. I remember the battery level was like roughly 90% the last time the tablet was working, so I don't know what went wrong .

I tried that but nothing happened .
Press all buttons on the side simultaniously untill fastboot/bootloader mode appears. This should work, no matter if your device is booted or not, or soft bricked or whatever. Then: http://forum.xda-developers.com/showthread.php?t=1907796 .
If it doesn't work however (like after 30-60 seconds), then connect your nexus 7 to your PC. Go to device manager and identify your device. Does it say apx-mode or something like that? Then your device is possibly hard bricked and you might find some answers here: http://forum.xda-developers.com/showthread.php?t=1879228 .
Your should not have used rootkits. Most of these topics appear after people using toolkit. Learn to use fastboot. It's the only program you'll need for the nexus 7. Yes, it's a command line tool but at least it forces you to think before flashing. For example, it was not necessary to downgrade your bootloader. I really don't get why you did that. Also, if you want to run a stable 4.1.2 without the annoying update messages, you can, for example, flash cyanogenmod 10. It's stable, very smooth, and way better than stock.

Thanks I did a search and finally found an answer. I was running fine on my N7 with PACMan and suddenly it got stuck booting up. So I booted into recovery and reflashed the ROM, and wiped dalvik and cache. When I rebooted it went to "Android is upgrading" like usual after wiping dalvik, then it got stuck there. So I rebooted again and nothing. Just a blank screen. Your suggestion of holding all the buttons down for 30-60 seconds awoke my Nexus. I'm going to wipe everything and start over.
Hello ! I really need help at this moment, i don't know what to do ... Really !
My Nexus 7 was in CM10, but 1 week ago, my tablet runs out of battery (turned off completly).
I plugged in, turned it on, and it bootloop on the Google logo. I mean i see the google logo, turns off and go back to the google logo, endlessly....
I tried the recovery mod to go back to the stock software... But i get the android's robot laying on it's back with a red icon....
No ADB status, and i cannot install the drivers with the nexus root toolkit ...
I powered it off, unplugged, plugged it, and let it charge all the night, but i get the same problem.
So .... I opened the back, see if there's any problem with the battery, disconnected and reconnected the connector, nothing suspect ... Turned on, bootloop on the google logo, super ... :good:
From this, i tried this method from XDA how-manually-unbrick-restore-your-nexus-7-s-factory-state-windows (can't post URL Ha!)
And tadaaaa, that's working now, i can access to my nexus 7 with the 4.1.0 Android, but ... I cannot access to the network ( it's connected but i get a grey icon with these little arrows...) and the battery shows 0%. If unplugged, my tablet turns off... Also, number of notifications show "......" as stoped working.
Now, i have the ADB status, that's pretty good, so that i can install the 4.2.2 Android version with the nexus 7 root toolkit. During the installation, at the end (when the tablet bootloop on the nexus logo with the color) my tablet turned off (maybe runs out of battery or a problem ? Don't know ...) ...
I plugged in the wall charger (not the computer) and my tablet restarted. See the google logo, after the nexus logo, and restart, endlessly ...
Now i don't know what i have to do, i'm completely lost. Do you think i can do something last, or i have to return my Nexus ?
Sorry if it's confused at some time, i've not a good english.
Thank you in advance
I think you failed to attach your battery correctly. Try disconnecting an reconnecting the battery. Than power down the tablet(Power button for 10sec if turns back on press power and volume down and choose "Power off") Than recharge your tablet using(Charger is better than PC). Now try flashing or installing Android. Should work. Let me know if doesn't.

I've already did that! It's correctly attached ...
I think that everytime i tried to install a new OS, my tablet turns off because he runs out of battery, whereas i though i was due to an error .
I've retried the method i gave above, Third times.
It's working now in Android 4.1, but if i try to update, my nexus restart again and again ...

Thank you jesus ! ^^
I've saved my nexus !
I post the solution:
You just have to follow the guide, named as "[HOW TO] MANUALLY UNBRICK / RESTORE YOUR NEXUS 7 TO IT'S FACTORY STATE (WINDOWS)" on this same website. (As i'm a new , i can't post URL at this time)
You must do the installation twice or more, because sometime, the nexus 7 reboot endlessly on the google logo, or on the nexus logo.
I needed to do this three times in a row to get a full and complete Android 4.1 working .
From that, i followed another guide. (because if i try to upgrade to the 4.2.2 OS, the nexus 7 is also blocked and i got a non stop reboot tablet)
Just go on google and type this "How to install cm10 jelly bean on the google nexus 7 using twrp recovery"
This is a youtube video that shows you how to download and install the Cyanogenmod10 in TWRP recovery mod.
(To access to the TWRP recovery mod, you can also use the Nexus 7 root toolkit by clicking on the Advanced button)
And voila, that's working now perfectly for me !
Hope this will help
So i got the new 4.3 update notification on my phone today. Eager to get it i started the installation (battery level was about 90%). After a while the installation went into a constant reboot, always went untill halfway of the progress bar and then phone went off and started again to same screen. I knew it was ****ed up so i went into recovery mode but then it starts to do the update again and i got the "ERROR" message. So i went into recovery again and now i get the "NO COMMAND". I was running 4.2.2 with everything stock, device was not even rooted...
Any ideas?

Unlock your bootloader, and flash the stock 4.3 image manually. Download it from here
https://dl.google.com/dl/android/aosp/occam-jwr66v-factory-08d2b697.tgz
After that, you can relock your bootloader if you want.

I've got very basic knowledge of android so i don't really know what to do... I imagine if i flash the stock manually i will lose all my data? Because in that case i might aswell go to the store and ask a new one since i still have my warranty...

Ok, if you have a store nearby, go to them. They will fix it properly. With basic knowledge, it's pretty dangerous.
Similar Prob
Hey guys,
I have a similar problem. Tried the upgrade to 4.3 and it stucked.... well now i constantly see the Google-X-symbol and thats all. Tried to unlock the bootloader via developer tools (for later flashing to Stock ROM) but there's no connection. Tried to replug it, etc.
When I start the bootlaoder (via Vol-Down and On-Button) I can choose the options (but recovery is not possible) But hm, the bootloader doesn't seem to be broken.
Can anyone help me? I'm not really a developer (although I work for a software-company) but I already unlocked and rooted devices and I have experiences in changing deep settings.
Help would be great!!! I don't want to sent it to google - I am lost without my S-Phone....
Thanks!
I have a similar issue, I found the update notification on my phone, went ahead with the update and it took ages! The battery was nearly full and the battery fully discharged while it was updating. I was at a friends house so no charger. When I got home I fully charged the phone and switched the phone on and got the nexus cross animation and thats all. I tried to enter recovery mode but got the no command icon.
Any help would be appreciated, I do have experience of rooting and flashing custom roms on my HTC Desire but have not touched the nexus since I got it. So everything on the phone is stock
Heres interesting, My wife tagged me into a facebook post telling peeps my phone was out of order, as she did it, the facebook app on my phone notified me of the tag!! Still got the nexus boot animation showing on the screen!

Ha, that's exactly the same issue.... Thank God I'm not the only one (sorry )
I got the "no command" error after my update this morning. My battery was pretty low, but the phone was docked. I just left the phone alone while I came here to investigate, and it eventually rebooted itself. Then it stuck on the loading X for around 5 minutes, but now it is optimizing my apps. Looks like it is going to work after all.
Mine has been on for a while but its not seeming to play. what mkes no sense is that it is switched on in the background but the nexus animation is the only thing it shows
I'm having the exact issue. I got my update notification this morning and it failed, going into an endless loop. I called google and they didn't know what was happening, so they're sending me a new phone. I don't want to wait for the new one, so I'm trying to fix this one still. I can start the bootloader, but I can't get into recovery. Is there a way to correct this through ADB?

When you get to the screen with "NoCommand" on it.
1. Press and hold power button
2. Then once you pressing the power button, press the Vol - Up
Thats it

Here is the fix for everyone
Ok, I just got off a chat with an Asus rep.
Step 1: Hold the power and volume up/down to get the android with the "start" option
Step 2: Use the volume down to select "recovery mode" It will now power off and power back up with the dead android and "no command" below it
Step 3: While holding the power button TAP, but DO NOT hold the volume up button. You will get an option to wipe all data. Do that.

2. When i start the phone just with the power button i just see the google logo.
3. When i plugin the power cable i don't see the battery for loading.
I got another device from google with horrorable battery power, so now i wanna try on my own the save my Tablet. I flashed my Galaxy Nexus and HTC HD2 couple of times, so i'm not a 100% Noob.
I was already looking in like 10 threads i found about problems nearly like mine, but i don't got the golden clue yet, sry.
I hope you can help me please.

I encountered identical problem on an N7 (2012) 32gb and try everything that I know how and always get the message ADB not found. Finally I use Skipsoft ToolKit and use option #9 Download, Extract and Flash Google Factory Stock Rom and it works . My N7 was returned to stock with latest firmware.. Of course you will lose all data and still have to unlock and root again
I am not a techie so I cannot explain the details but only share my experience.
I hope it will work for you

If you can't see the white battery picture when plugging in the power cable, I suggest you use AC power, and if you are, try using a different USB Micro cable.
Hi guys,
I had Pure nexus rom installed:
http://forum.xda-developers.com/nexus-4/development/rom-pure-nexus-project-layers-t3237366
and everything worked fine for weeks. Yesterday I noticed that my nexus 4 is using battery too much, without any reason.. Then my phone turned off, try to restart but it was stuck on google logo. At that point there was 20 or 30% battery left. I boot it to recovery, wipe everything and tried to restore factory settings, cos I didnt have any backup on phone. But again it was stuck on google logo.
So now I cant boot it cos there's no system installed on it, basicaly there is nothing on my phone. I tried Nexus Root Toolkit, but my pc dont recognize my phone, when I boot to recovery it's still the same, so I cant install drivers..
At this point, I have no idea what to do.. Can anyone help pls?
Thx

Thx for quick reply !
Yes, I'm using win7 64x, I tried all usb ports and 3 different cables and nothing. I can get into fastboot and recovery, but pc still don't recognize anything..
i am currently under the same situation
only difference is i can still fastboot and flash a recovery (twrp for that matter)
afterwards, when booting to recovery - i can install a rom
once the rom is installed, reboot does not boot into the ROM and instead just displays the google logo - then vibrates a little - then the screen turns off
I just tried on 2 other win7 pc's, still nothing.. Nexus root toolkit just can't establish adb/fastboot connection..
edit: other thing I tried is to copy ROM file on usb stick, and then connect usb stick with micro usb cable to phone, and when I'm in recovery (twrp 3.0.2-0) there is just ''internal storage'' option.. Is that normal, should twrp see external USB drive? Cos I'm thinking that maybe something is wrong with usb charging port (I replaced that board month ago).
Hi,
I have a similar problem:
I had my mobile in working condition and once when upgrading the OS to 5.0.1, it downloaded the OS and was upgrading. During that process, the charge got over and hence the phone was shutdown. There after, it was not proceeding further from Google screen when trying to reboot. So, i thought battery is dead and replaced the battery with a new one. Now, i am getting the following problem:
The phone doesn't turn on(not even getting GOOGLE screen now). But, If I keep holding power button and Volume down button and try to insert the charging cable immediately then i get the boot menu but it wont stay there for even a second and goes to GOOGLE logo screen and gets shut down. Please help me with this.
Hi guys,
I menaged to fix the problem, my problem was charging port (smal L shaped board) that I replaced month ago. That's why there was no connection.
I got another one this morning from ebay, and Nexus Root Toolkit established connection immediately.

That looks like a stuck power button.
Try just holding the volume down button and plugging the charger.
If you see the fastboot screen, you have a stuck power button.
Just experienced this issue on a Nexus 5 and I was able to recover from it by "massaging" the power button for a while.
