[TUTO+VIDEO] Unlock Bootloader-Flash Recovery-Root-Restore Back the N7 FLO- KK 4.4.4

Search This thread
Hey guys, I've made a pretty simple video tutorial on how to Unlock the Bootloader and Root the new Nexus 7.
Here it is:
Link: http://youtu.be/MQmfIY9AB0o
I know I don't have a well known name on the forums at all, but I thought it would at least be nice to post this. :good:

Can you use clockwork instead of twrp in your instructions? Also, have you seen a way to return to stock, in case we see defect issues on these new tablets?

It would be better to oepn a thread in General for your video and not here.
It's not the place to discuss about your video.
So please open a thread. I've added your video to my Index => Post #4 ;)
Thanks

Thanks for the tutorial. Quick question...

I don't have my 2013 N7 yet, should be here tomorrow. But I seem to recall that with every phone I've had and with my original N7, I had to install drivers to get adb to work. Is that still true with the 2013 model? If so, does anyone have a link to the drivers that will work with Windows 7?

Thanks!

Brick Chances

I would love to root my new Nexus, but I'm worried I'll brick it, what are the chances of that happening? Also, if it bricks, is it completely dead?

Got stuck on < waiting for device > when trying to flash the recovery.

Tried from 2 different PCs Win XP and Win 7. The same problem.

Any ideas?


Thanks

USB Debug is enabled. And I was able to unlock the bootloader as per instructions.

Just to let everyone know I've found the issue with my Nexus 7 reporting as 'offline' while using OS X.

I was finally able to get a copy of the newest version of ADB that I needed, version 1.0.31. I was previously using version 1.0.29, which is why I was unable to use ADB with my device.

I've uploaded a copy of this version in case anyone else has this problem and needs the newest version of ADB for Mac OS X ONLY.

Here's the download link: http://wadegarrett.com/adb.html or direct download here

I followed your instructions as closely as possible, but seemed to run into a problem when attempting to flash TWRP; currently, the device will boot into the OS without any issue, but all attempts to boot into Recovery just bring up the image of the Android robot on his back with the red exclamation point triangle coming out of his chest. Is this fixable?

Is your device is unlocked or not ?
Have you tried to install TWRP recovery only ?

The device was successfully unlocked.
I have only attempted to install TWRP as indicated in your instructions in the first post. The output following the "fastboot flash recovery recovery-twrp.img" from Recovery mode is as follows:

sending 'recovery' (9612 KB)...
OKAY [ 0.327s]
writing 'recovery'...
OKAY [0.507s]
finished. total time: 0.034s

And you cannot reboot to your recovery after the recovery install ?
To boot your device into Recovery, press the volume key (+/-) until Recovery Mode is displayed. Then use the power button to select it and the device will reboot itself into the TWRP Recovery Mode.

When is the volume key pressed? While the device is off? If so, the device does not do anything.

EDIT: I was able to get into Fastboot and reinstall the recovery; I would make it a point for anyone reading that Fastboot is pressing DOWN and POWER while the device is off.

This guide worked well for me. I was able to unlock the bootloader, and it appeared that I was able to install the TWRP recovery image. However, when it went to reboot, the Nexus 'X' logo is looping. What's the best way to fix this? I can't access the device through the cmd prompt either.

EDIT: Nevermind, was able to get into the TWRP recovery image (I was panicking and didn't press the right buttons).

Note: I let TWRP install SuperSu for me, instead of downloading it and moving it on internal storage myself. Don't know that had anything to do with my issues but just wanted to share a heads-up.

I've done the same thing - let TWRP install SuperSu, and now I'm stuck with the Nexus X logo. I can reboot into TWRP, but can't figure out how to get the supersu zip copied over now. While in TWRP my PC sees the nexus as "Flo" and adb won't recognize it. Can't install the adb driver. So adb sideload in TWRP fails.

Can you explain how you fixed this, or can anyone else give some advice? How can I get the supersu zip onto my nexus in order to flash it and boot?

Thanks!

RESOLVED.
The problem is that instructions not that clear at this point.

You have to flash recovery not when the device is booted into the system but when device is booted into bootloader.

just do
adb reboot bootloader
wait till device is in bootloader and than try to flash recovery with fastboot.

Found the answer from antiochasylum in another thread here: http://xdaforums.com/showpost.php?p=44122738&postcount=30

Here is the stock recovery. https://www.dropbox.com/s/ich3czqd99bq0f3/recovery.img

Boot back into recovery, flash that recovery, then lock your bootloader. Reboot - it probably will not boot up again. This time, go back to fast boot and unlock the device. REBOOT, and it will boot up. Then once your booted, put SuperSU on internal card, go back to fastboot and flash TWRP, then go into recovery and flash the SuperSU.

I'm trying to simply unlock my Nexus 7 using Ubuntu. I use command "./adb reboot bootloader" and that takes me to the bootloader. Then I run "./fastboot oem unlock". Nothing happens on my Nexus screen, but the terminal says "< waiting for device >" indefinitely. What am I doing wrong?

EDIT: I answered my own question and I'm sharing it for the sake of others. This command unlocked the boatloader - "sudo ./fastboot oem unlock"

    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 ;)


    ....-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.


    ....-ox=O=xo-....

    Process to unlock bootloader of your Nexus 7 FLO

    -5: The tablet will go back to the bootloader screen. Press Power button to select Start to reboot into the unlock device

    Before to install the TWRP recovery and applying the root, you need to download the latest version of the TWRP recovery and the latest version of SUPER-SU that you need to push to the root of your sd card - For downloading these files follow the links below ;)
    ....-ox=O=xo-....

    Process to install TWRP recovery on your Nexus 7 FLO
    -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:

    -4: The recovery will be flashed and the progress could be observed in the CMD window itself.

    Note: To boot the Nexus tablet into Recovery, press the Volume keys (up/down) until Recovery Mode is displayed. Use the Power button to select it and the device will reboot into the TWRP recovery Mode.

    ....-ox=O=xo-....

    Process to root your Nexus 7 FLO - Update

    [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.
