HELP! Bricked Nexus 7, cannot boot into boot loader

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.

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.

Help, My Nexus 7 is dead!

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.

help pls, nexus 4 softbricked

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

Can you get into fastboot? Are you using Win7? Tried different USB ports and cables?

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.

Nexus 7 dead until i connect it to a pc/laptop PLEASE HELP!

So my girlfriend was using her Google Nexus 7 2012 of 32gb only Wi-Fi triying to play the EA game "The Simpsons: Springfield" while the tablet was charging and when the game loaded it was running slowly till it frozen and then she tried to see all apps open with the 3rd button, she could pull down and see the notification drawer, then she push the 3rd button (that one on the right) but the tablet didn´t respond, instead it will just pull back the notification drawer, then the tablet started to show a notification in the middle of the screen that said "the system process is not responding" (We don´t have screenshots from this notification, that´s what she remember's and I am translating into English from the Spanish she saw) with 2 options, "wait" and "close", she pressed "close" and then it showed another notification saying "the user interface is not responding" (We don´t have screenshots from this notification, that´s what she remember's and I am translating into English from the Spanish she saw) with 2 options, "wait" and "close", she pressed "close" and I am pretty d#%n sure that it was in that moment when it got f$#%&d. Then she left it alone for like 10 minuts but it didn´t do anything, so she attempted to restart it by pressing "power + volume down" buttons together for 10 seconds and when she let the buttons go, that´s when she realized it was gone all wrong, what she saw was this "Android Robot with his belly opened with a lot of words on the down - left of the screen which ended up with look state - unlocked, it also had two arrows on the right-top of the screen, one pointing up and one pointing down, there was also on the top of the screen a red arrow with black background and inside that red arrow had written RECOVERY MODE" then she used the arrows on the right to move what was written on the red arrow, there was at least 3 options, she remember´s the first which was "RECOVERY MODE" and the second that was "POWER OFF" she is also pretty sure that it was a 3rd option but so far she doesn't remember. So she chosen power off with the power button and the tablet powered off automatically and she waited to see the tablet charging but it never appeared, later on, she tried to turn it on, it won't happen.
So now the tablet is totally dead and the only sign of life i have seen is that sound when i plug in the tablet into my pc or her laptop and press the power button, that sound that minds that a device has been mounted and the same sound when i unplug it from the pc or laptop. I have no idea of what should I do with her, my best hope is that I found a genius here patient enough to help me out with this peace of technology. :crying:

Connect to Nexus Root Kit and try to flash stock ROM. There is option for non bootable devices
Sent from my Nexus 4 using Tapatalk

Which Nexus Root Kit?
I only found here the Wugs Nexus Root Toolkit, I already installed the Wugs Nexus Root Toolkit v2.1.6 but I couldn't find the proper way to use it for a non bootable device.
Am I using the correct Nexus Root Kit?
If yes, please tell me: where can i find a step by step guide to solve the problem?
If nope, where can i find the correct Nexus Root Kit with a step by step guide?
Thank's so much in advance for your help, I already tried with the Wugs Nexus Root Toolkit v2.1.6 to flash stock ROM but as the tablet is dead, I couldn't boot it to bootloader, obviously I couldn't either turn the tablet on to allow usb debugging, for all matters, the toolkit need's adb connection to work, and I couldn't find the way to start an adb connection.

Make sure the tablet is not stuck in APX mode. To get out of this: connect the tablet for some time (at least for about 1 hour) to the charger then press for about >=20 sec the power button *only*. Release the button. If the tables was stuck in APX mode, now it should have exited that mode. Now you should be able to boot to bootloader / recovery / system. If this does not work, I suppose your tablet is bricked ...

Its correct NRT. First step is to download correct drivers and make sure it passes full driver test and adb and fastboot work. If that's the case then everything can be flashed (bootloader, recovery and ROM). Here is link to a manual process that shows steps but NRT does it automatically. Look at flashall script
http://www.laptopmag.com/articles/how-to-hard-reset-a-bricked-nexus-7-with-your-pc
Also try connecting to charger, keep it charging for 30 min or so and then try power button

Thank's!
Thank's to much for your glorious help!
I tried connecting to a charger about an hour and half and then power button, nothing happened, in approximately 24 housr from now I will follow the step by step guide to unbrick the tablet, thank's for the link, I hope it work's, I let you know later on.

If your device is really bricked, there is no change for reviving it, sorry.

Try installing just adb/fastboot (adb-setup-1.4.3.exe) from https://drive.google.com/file/d/0B0MKgCbUM0itNVB1elljU2NPR0k After installing open cmd window as admin, go to c:\adb and see if "fastboot devices" returns anything. If yes, then download recovery TWRP image (twrp-3.0.2-0-grouper.img) to same folder and type "fastboot boot twrp-3.0.2-0-grouper.img". If recovery comes up then you have options to flash some ROM. To permanently install recovery "fastboot flash recovery twrp-3.0.2-0-grouper.img" Boot loader can be flashed in the same cmd window, If it worked then reboot into bootloader with fastboot.

Why is everyone giving him advice on unbricking when he can't even power on the tablet.
Yeah, you can use ADB to fix a tablet that won't power on so the computer can even load a driver for it. LOL
<sarcasm>
Look, the Nexus 7 has random charging issues especially when it gets drained down to zero battery.
I deal with it on mine sometimes.
Not saying this is your problem, but since you can't even power the device on, it's the first thing I'd look at.
Gotta pop the back cover and reseat the battery connector.
Then try charging again for a couple hours.
Ugh, I've got to do it to mine right now too.
For the third time since I've owned it.

Yep, reseating the battery cable fixed it once again for me.
