Try flashing the images MANUALLY in fastboot. Try erasing caches from fastboot.

Don't blame Google.

Actually Google (or Asus) is to blame. It's been widely reported across many sites.

http://androidcommunity.com/lollipop-not-good-for-nexus-5-and-nexus-7-units-being-bricked-20150413/

Same thing happened to my brothers Nexus 7 which is a completely unrooted & stock Nexus. It's never been unlocked or tampered with in any way. Wouldn't boot after the lollipop OTA and wouldn't even enter recovery and no ADB to flash a manual image, so some people are screwed. That shouldn't happen on a stock device. Luckily Google replaced it, but it's definitely an issue with their OTA's affecting some devices. And some people aren't even getting theirs replaced.

-1: Download the latest TWRP recovery image file
Download link- TWRP

-2: Open the folder where the recovery image file has been downloaded and rename your recovery "recovery-twrp" simply. Re-open your previous Command Prompt window.

-3: Type the following command to flash the recovery image file
Code:
fastboot flash recovery recovery-twrp.img
-4: The recovery will be flashed and the progress could be observed in the CMD window itself.

you need to be more specific on the command directions. "hold shift, right click where files are at and click open command window here" thank god there was a video

also after installin twrp, you copy the super su zip on the main internal sd card, then boot into twrp and then click install then flash the super su zip file.

the way you have it on the directions does not work

This tutorial All In One is for all owners of the NEW NEXUS 7 FLO (2013 Edition). I've tried to be clear, helpful and simple.

This all seems to be with Android KitKat 4.4.4 can this process be done on a Marshmallow 6.0.1 device as well and would I need to down any files that would be specific to Marshmallow. I am looking to just root may current 6.0.1. Thank you in advance!

Hey guys, I just purchased a used Nexus 7 (2013) on swappa. its running 6.0.1, Build number M0B30P, Kernel 3.4.0-g1fc765b. The bootloader is unlocked. Do i need to take any special precautions when flashing TWRP/superSu since this isn't on the 4.4.4 that this thread was written for? Thanks a lot
 
im on kitkat 4.4 rooted with twrp.. can i just flash pure nexus rom 6.01 easily on kitkat? ty
Yes you can without problem.
Don't forget to do a backup before to do something.
And you need to update your bootloader, and need to do a clean install (wipe dalvik, cache and system).
Good luck and enjoy good time with your N7

Yes, of course you need to unlock your bootloader, and it's really easy....use this process.
For my N7, I've never used tools :cool:;)

I want to root my wifes N7. She is on stock 6.0.1 Android build number MOB30X . I've just unlocked her bootloader using Android ToolKit V2.15. Can I use same Tookit and root her device and than flash CleanROM 7.1 MRA58U that I have on my Nexus 7 tablet. This is Android 6.0. that I have . Do I need to flash factory images first or this will be done by Toolkit automatically when I select option 3( 1-Click for all(unlock , root,busybox,rename, custom recovery).???

    ....-ox=O=xo-....
    POST #1 => [TUTO + VIDEO] AIO Unlock Bootloader, Flash Recovery (TWRP) and Root your Nexus 7 FLO​

    ....-ox=O=xo-....
    POST #2 =>[TUTORIAL]Download Factory Images Nexus 7 FLO - Restore back STOCK with latest KK 4.4.4
    ....-ox=O=xo-....
    POST #3 => [HOW TO] FLASH MORE FASTER WHEN YOU USE FASTBOOT LINE COMMAND



    ....-ox=O=xo-....
    Warning!
    This guide and its guidelines are meant only and only for the new Nexus 7 "FLO" (2013).
    Do not attempt to try this on the older Nexus 7 or any other device.
    Applying this to any other variant might brick the device.
    Read and understand the instructions carefully before proceeding any further.
    ....-ox=O=xo-....
    THIS GUIDE IS ONLY FOR WINDOWS
    1) This point is really important. You’re going to lose all your datas on the device including the internal storage. So back everything up.

    2) Download and Install 7zip or any other archive manager as WinRAR etc...

    3) Download and install Android SDK

    OR

    3Bis)Download The ADB and Fastboot Tools in the same Tool ==> platform-tools.zip - md5: 15e771613370afe3c70e0be1454d2ef1 - size: 346.8KB

    4) Put these 3 files in where your fastboot folder is installed; ex => => disk C: root
    Unzipped this file on the folder "platform-tools" and you will find 11 files:
    - aapt
    - adb
    - AdbWinApi.dll
    - AdbWinUsbApi.dll
    - aidl
    - dexdump
    - llvm-rs-cc
    - fastboot
    - dx
    - NOTICE
    - source.properties


    5) Enable USB Debugging Mode on the tablet to connect it with the computer and use Android SDK with it.
    { Press Menu =>> Settings =>> Applications. From there navigate and click on Development option then check the USB Debugging Mode.}
    If you don’t see the Development Options, you'll need to open the Settings app and scroll down to the bottom. Once you get there, tap “About Phone”. Scroll to the bottom again, until you see the Build Number entry.
    Now tap Build Number a total of seven times. You'll see friendly developer messages starting with the fourth tap. After the seventh, you'll see a message congratulating you for unlocking Developer Options. “Now you are a developer".

    6) At least 70% battery power to avoid uncertain shutdowns during the process.

    7) The tutorial is compatible only with the Nexus 7 wifi (2013) FLO.

    [TUTORIAL]Download Factory Images Nexus 7 FLO - Restore back STOCK

    [TUTORIAL]Download Factory Images Nexus 7 FLO - Restore back STOCK - With latest version KitKat 4.4.4

    Find your Factory image for your N7 FLO - KitKat KTU84P - Download Link - - is very useful if you need to restore back your device to Stock after any modification you’ve made. If you have rooted your N7 Flo, unlocked its bootloader, installed custom recovery and roms and finally you want decided to getting back to official firmware and then to get or accept future OTA updates again. It’s the best way to restore back your device to Stock.

    Coming back to stock is also useful if you have some bugs (for fixing it), Bootloop, stuck in boot screen logo and freeeeezzziiiinnnngggg, etc....
    But before to going back to stock, you need to read completly the tutorial and need to know
    Your bootloader will be “LOCKED or UNLOCKED” when you want.


    1 - Where I can can find the right Factory Image for my Nexus 7 Flo and which files I need for proceed ?
    But first download and install the necessary files prior to execute this properly. Download the full factory image corresponding to your exact mode which includes the full system, bootloader, recovery, kernel (boot.img).
    Unpack the TGZ Version (tar/gz) or Zip Version Archive into its own directory. I use 7-Zip, but you can use any tool that reads gz and tar.

    qose.png


    1. Factory Images "razor" for Nexus 7 [2013] (Wi-Fi) - 4.4.4 (KTU84P) - Download link

      If you have already installed those files, just check theirs.
    2. Java Runtime Environment.
    3. Android SDK | Android Developers.
    4. Platform tools
    5. Fastboot files

    2 - PREREQUISITES
    First make sure that your battery is fully charge 100% and BACKUP ALL YOUR PERSONNEL DATA

    [1] - Make sure you have USB debugging turned on. For security purposes, you can turn it off after we're done

    [2] - Plug-in USB cable and If you are booted into Android, open a command prompt to your ADB and Fastboot directory,

    [3] - In case you are not unlock, you need to unlock your bootloader, enter the following commands:
    Code:
    fastboot oem unlock
    If your tablet hasn't already rebooted automatically, type:
    Code:
    fastboot reboot
    NOW WE ARE READY FOR PROCEED TO RETURN STOCK

    3 - RUNNING FACTORY IMAGE

    If you want to keep your data intact, don't skip this step, (if you do your data will be wiped :( )

    With your text editor (for me it's Notepad ++,
    [1] - Edit (be careful not to run it by accident instead of editing)
    [2] - flash-all.bat (if you're on Windows)
    [2a] - flash-all.sh (Mac, Linux)
    [2b] - and remove "-w" from the fastboot update command

    For example, if the line reads fastboot -w update image-razor-ktu84p.zip, it should now read: fastboot update image-razor-ktu84p.zip. The -w option instructs fastboot to wipe data.
    [3] - Reboot into the bootloader and run the appropriate flash-all script:
    Code:
    flash-all.bat
    4wii.png

    Done, your Nexus 7 Flo is now coming back and running Stock Android KK 4.4.4

    uqpv.png



    In Case you want to come back completely to Stock, for warranty or security purpouses, you need to re-lock your bootloader now.
    Enter the following commands
    Code:
    fastboot oem lock
    If your tablet hasn't already rebooted automatically, type:
    Code:
    fastboot reboot
    Done!

    Thanks philos64. My problem now is that I couldn't even boot into the OS, I can get into Bootloader mode or Recovery mode, but I couldn't factory reset (says "failed") or boot pass the Nexus screen. (stuck there for more than 15 minutes).

    I'm sort of a noob, any help will be appreciated.

    this just happened to me. I fixed it by:

    1. go into recovery and FORMAT DATA in the wipe menu

    2. then FACTORY RESET

    3. restart to os


    i didnt need to download the system.img like the above link

    What exactly is "FLO"?

    Is this different from my Nexus 7 Full HD (2013) or it's the same thing?

    From the cyanogen site it implies that "flo" is basically the same thing but I'd like to be sure:

    "Codename: flo"

    ?

    Flo is the WiFi only version of the nexus 7 2013. There is also deb which is the WiFi and cellular version of the nexus 7 2013.
