Hi all
I have several years experience from rooting and applying all kinds of ROM's om both Symbians, Motorola OS, Android and WM devices but I am completely stuck when trying to "fix" the problem with non-existing SD card support on the Xoom.
What I have been looking for is a guide that walks you through Unlocking, Rooting, adding CWM and finally replaces the kernel with a "better" one. I have of course found all kind of guides on any of the topics above, but all of them assumes that you already have performed one or another of these steps.
So if anyone could be an angel and summarize the steps (links are ok) with the assumption that the reader (I) have
- oem locked
- no cwm installed
- unrooted
- Wifi only
- updated 3.1 honeycomb device.
I will certainly cry of joy if someone can do this for the good of the community. I am sure that many like I have already tried both this and that, and bricked or soft-bricked (I did) their devices while trying to get the god damned sd card to become functional . My own device has now been resurrected from coma (RSD Mode 2) and is now alive again, thanks to "fastboot oem unlock" but I can not for my life get the CWM to work. I have installed the recovery-Tiamat-R4c-100611-1150-cwm.img with fastboot. No errors reported either on the tablet och in Windows during flashing. But when pressing VolUp during boot, I just get stuck in "Starting RSD protocol support 3". I can boot normally if I dont press any button. Fastboot mode works too.
Below is a slightly modified of Land Master's NOOB guide. I have only updated a couple of links. I followed this guide when I originally rooted my Xoom, and it worked perfectly. But note that I have not tested this with the updates. All credit for this goes to Land Master!
USE THIS, AND ASSUME ALL RISKS. IT HAS NOT BEEN TESTED WITH THE UPDATED LINKS!
WIFI ONLY! WIFI ONLY! WIFI ONLY!
If you use this guide, or any other guide for that matter, make sure that you read it, reread it, (10 times!) and fully understand every step. One hour now, spent studying this, will save you 10 hours of headaches later. Make sure you follow every step EXACTLY!
"This tutorial was written for the NooB’s among us (like me) that are new to this stuff and are having a hard time “piecing together” all of the steps. While I am actually a not quite a beginner, NONE of these steps/methods/files have been developed by me. I have simply compiled the procedure in a document that I hope will be useful. With this in mind all the credit belongs to the many individuals that contribute in the XDA Developers forum. I have reviewed many posts by many people and have used all of the information along the way.
A)*Installing ADB
ADB stands for Android Debug Bridge and simplistically stated will be used to send commands to your XOOM using the keyboard on your PC. In essence your PC will be acting like a terminal. ADB is included in a package known as the Android SDK. The following steps should be taken to insure a successful install of the SDK, therefore giving you access to ADB.
1.*Install Java JDK :*http://www.oracle.com/technetwork/ja...ad-346242.html
a.*Download appropriate Java SE Development Kit (JDK) from link above
b.*Double click to Install JDK
c.*Accept Setup Defaults
2.*Install SDK Starter Package:*http://developer.android.com/sdk/index.html
a.*Download SDK Starter Package from link above. There are versions available for Microsoft Windows, Linux and Mac OS X. In case of Windows, both an installer and a zip file are available but there isn’t any need to use the installer as a formal installation is not required. Download the ZIP file.
b.*Once you have downloaded the SDK, simply extract the compressed file to a location on your computer. In our case, we have extracted it to the root of our C drive and that makes*C:\android-sdk-windows*the installation location of the SDK. From here onwards, we shall be referring to this location as the ‘SDK folder’.
3.*Download the SDK Platform Tools using the SDK Mamager.
a.*Browse to the SDK folder and launch SDK Manager.
b.*When launching it for the first time, it will present you with a window to choose packages to install. The first option begins with ‘Android SDK Platform-tools’. Make sure it is checked, and uncheck all the other packages for now. You can check/uncheck a package by simply double clicking on the package. Again, the only package you want to install is the Android SDK Platform-Tools.
c.*Once the process is done, you will have a ‘platform-tools’ folder inside your SDK folder. That folder will include ADB and all its dependencies.
d.*Make a copy of the File “fastboot.exe” which is in the “tools” directory and place it in the “platform-tools” directory.
B)*Install XOOM USB Driver
Just to be sure your XOOM is recognized by your PC it is recommended that you install the latest USB drivers for your system.
1.*Install MotoHelper :*http://www.motorola.com/Support/US-E...arging-Drivers
a.*Download the Driver with MotoHelper from the Link above
b.*Double Click downloaded file and follow on-screen instructions to install.
C)*Unlock Bootloader
Unlocking the bootloader gives you full control over the device so you can flash new Recovery’s, kernels, ROM’s, ETC.*THIS STEP*WILL DELETE ALL DATA AND SETTINGS ON YOUR XOOM.
1.*Put XOOM in Debug mode
a.*On the device, go to home screen, press*Apps*> >Settings>>Applications>>Development, and enable*USB Debugging.
b.*Now connect your XOOM to the PC via USB. New hardware installation should begin and it will start looking for and installing the drivers.
c.*A prompt should appear that states the drivers were installed successfully. On my PC the AutoPlay Device Options also appeared. I clicked “Open Device to View Files” and saw the device Storage with 27.8 GB free of 28.7 GB.
2.*Execute ADB Commands
a.*Open a command prompt by navigating to the ‘SDK Folder’, Holding the shift key, right clicking on the “platform-tools” folder and selecting “Open Command Window Here” from the popup menu.
b.*In the new command window type:*adb reboot bootloader*and press enter.
c.*Wait for the Dual Core screen with “Starting Fastboot protocol support” in the upper left corner to appear and then type:*fastboot oem unlock*in the command window and press enter. You should see: “To continue, follow instructions on the device’s display…”.*
d.*Read the WARNING on you XOOM and either Continue Below or Cancel following the on-screen instructions.
e.*If you decided to continue then on the XOOM Push Volume Down Button to change the selection from “Cancel” to “I accept” and then press the Volume Up to select that choice.
f.*You will be questioned again so Push Volume Down then Volume Up to confirm you want to UNLOCK your device. You will see “Device Unlock operation in progress…” “Formatting UDA”
g.*When the operation completes the device will read”Device unlock operation done – rebooting…” and the device will reboot. The windows new hardware “gong” will sound a couple of times during this procedure. After this step when my XOOM rebooted I also saw an “MTP Device” driver Install dialog box on my PC. Unplug the device, and quickly perform the initial set-up. You can “Skip” any steps that will allow you to (like WiFi setup). Just get back to the home screen and continue below:
h.*Verify that USB debugging is still enabled and if not re-enable it as outlined above.
i.*Re-connect your XOOM to the PC and close any AutoPlay dialog.
D)*Install Custom Recovery
A custom recovery allows you to flash files created by community developers such as ROM’s, Radios, Kernels, Themes, ETC. It also allows you to perform special tasks such as system backup’s, partitioning, cache wiping, ETC. As of 6/19/2011 the generally accepted custom recovery for the XOOM is ClockworkMod Recovery v3.2.2.0
a.*Download Clockwork Mod recovery image (not .zip file) from here:http://forum.xda-developers.com/show....php?t=1074979*
CAUTION: Do not install CWM 4.0.0.X from ROM manager!
b.*Place the File “recovery.img” that you just downloaded in the “platform-tools” directory
c.*In the previously open command window (if you closed it then re-open as described above) type:*adb reboot bootloader*and press enter.
d.*The device will reboot into bootloader mode (as described above) and when this completes type:*fastboot flash recovery recovery.img (name must match name of file)
e.*Check the screen of your XOOM and see: “Flashing StorMgr partition recovery STATUS: - done!*
f.*Type:*fastboot reboot*in the command window and press enter.
g.*Wait 3 second after the Moto logo is seen, then pushed Vol Down
h.* Android recovery menu visible, press Vol Up. Go straight into CWM.
i.*Navigate in ClockworkMod Recovery by using the volume up/down to “move” and the power button to “select”. Look for reboot system, highlight it and hit the power button. Your zoom will reboot normally.
OPTIONAL STEPS
l.*At some time later (AFTER YOU ARE ROOTED) to avoid the need to execute ADB commands to enter recovery, I suggest you look for a free application called “Quick Boot”, by Sirius Applications from the market.*
m.*Once Quick Boot is installed run it and simply select “Recovery” to boot into ClockworkMod.*
Next Step: Following Public Animal's guide to rooting >*http://forum.xda-developers.com/show....php?t=1075260*
Last step (optional) install Tiamat 1.0 ROM >*http://forum.xda-developers.com/show....php?t=1117004
Thanks a lot! I am with you all the way to step H (adb reboot recovery). This step ends with the Android, yellow triangle and an exclamation mark. Nothing more. So something must be wrong with the recovery image.
In both your links and other links to the recovery image, the name "recovery-solarnz-XXXXXX-XXXX.img" is used. But the links always leads to the image "recovery-Tiamat-R4c-100611-1150-cwm.img" instead. Could this be the problem? If so, what should the XXXXX be replaced with (for googling).
Thanks again for the guide. Sooner or later I *will* succeed!
Edit: Could this post be something that explains why my CWM flashing does not succeed? http://forum.xda-developers.com/showpost.php?p=13747198&postcount=18
And since the device still not is rooted, I can not rm the suggested files ... gaaah

Not sure that I've completely understood your question, but when you type:*fastboot flash recovery recovery.img, make sure to replace the words "recovery.img" with the actual name of the recovery image file.

The name of the file is "recovery-Tiamat-R4c-100611-1150-cwm". So you should type:*fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
It actually worked! What I did was this
1. adb reboot bootloader
2. flashed the same recovery image that I mentioned earlier
3. fastboot reboot
4. applied the 3 second wait once the Moto logo was seen, then pushed Vol Down
5. Android recovery menu visible, press Vol Up. Now I got straight into CWM !!!
6. (prepared the sd card on my SGS with the zip files)
7. Choosed Install zip from sd card and flashed the wifi-root image
8. Reboot the tablet and verified with RomManager that I now had root
THANK YOU VERY MUCH FOR NOT GIVING UP ON ME

For simplicity I renamed the zip to recovery.zip before copying it to the folder and flashing it (see next post also!)
I am going to modify the instructions. Is this correct for what you did?
"f.*Type:*fastboot reboot*in the command window and press enter.
g.*Wait 3 second after the Moto logo is seen, then pushed Vol Down
h.* Android recovery menu visible, press Vol Up. Go straight into CWM.
j.*When my device rebooted into recovery I also saw additional Device Drivers install. This took a little while and I waited to do anything until I received the “Device Driver Installed Successfully” dialog."

Yes, everything except the last step (j). I did not see anything on the computer screen. But now I have managed to install CWM, root it and install Tiamat 's latest kernel. The external sd card is now visible inside /sdcard/external! Success!

This is an amazing guide! cam30era you and LandMaster are the bomb!
May suggest one thing? When reading it through, I think a real noob might be confused with the asterisks that are on either side of many of the adb commands.
Anyway this should definitely be a sticky!
actually I sat down and wrote my own guide, starting from scratch and ensuring that every assumption and requirement was explained. I called it "idiots guide to ..." . Maybe it would be a good idea to consolidate the best from both guides into a -definitive guide-. What do you think?
Oh, the thread is in the Android development forum. Mod is welcome to move it if so needed

CWM won't boot.
For the life of me I can't understand what I'm doing wrong. US Wifi Xoom with 3.1, bootloader is unlocked, but not rooted. I use fastboot to flash the latest recovery img, 3.2.0 I beleive. Says it's successful, but like many on here when I either use "adb reboot bootloader" or if I time it and press volume down to get into the recovery, I only get a picture of the robot with the triangle. I can press volume up+power and I get the stock recovery.
I've read every post I can read but most people who have resolved the same issue were just not flashing the correct image. Which I'm sure I'm doing correctly.
Amy help would be appreciated.

Hehe, no disrespect but since the bookshelves are drenched in "for dummies" and "for idiots", I thought it might be ok to use that title. Glad that you finally succeeded!
Attempted to flash Liquid Jelly Bean, then got stuck on the animation boot screen. I've tried Root tool kit for unbricking and setting it back to stock. Tell me it's successful but stays stuck on the animation screen.
I've also tried to unbrick manually however even though I have the correct files placed in my Platform Tools folder of Android SDK ... I constantly get stuck at the CMD prompt steps. Any time I type in "ADB reboot loader" or ..."fastboot flash bootloader bootloader-grouper-3.34.img" or anything similar I get the error message in CMD saying "___ Is not recognized as an internal or external command"
I'm not sure what to do. The bootloader does say that my device is locked, I just can't get passed the splash screen!

Nothing will boot now and it's currently locked. Any time I hit "Start" it says "Booting Failed"
My CMD now says; Error: Cannot Load "Bootloader Grouper-3.34.img"

Can you get into bootloader and then recovery by holding the power and volume down buttons? Was ADB actually working before all of this??

No I can't get into the recovery at all. When I turn on the device I don't even need to use the rocker keys to get into bootloader either. Actually my bootloader is a bit different now too. I have the 'Google' logo and at the top the regular options for Start, Recovery, Power Off, etc.
In simple terms: I can't even get to the animated splash screen anymore
Open the command prompt IN the directly WITH fastboot
Fastboot oem unlock
Then wipe / flash factory images. Fastboot -w update image whatever the image name is.
Then uninstall / delete that stupid toolkit and never use them stupid craps again.
Are you still able to communicate with the device via fastboot? If you issue the command 'fastboot devices' does it return a serial number?
Edit: I'm going to bed so if you are able to use fastboot, download the factory image pack from https://dl.google.com/dl/android/aosp/nakasi-jro03d-factory-e102ba72.tgz
Extract the archive. Inside are there will be an install script, manually issue the commands contained in the script in fastboot. The only thing you need to add is the location of the .img and .zip files from the archive you extracted e.g. 'fastboot flash recovery c:/Users/name/desktop/recovery.IMG'
There is no reason this will not get you up and running again.

Thanks for your response.
I've followed the instructions in the file. From previous research, I've had these files. My device does communicate with Fastboot. When I give the command for Devices it gives me my serial. Also, when I ask it to reboot-bootloader in CMD it does.
My issue is when I get to "Fastboot flash bootloader-grouper-3.34.img". CMD states "Error: Cannot load bootloader-grouper-3.34.img"
I've followed the commands previous to that. (Erase boot, cache, recovery, system, userdata)

Fastboot oem unlock
Then wipe / flash factory images. Fastboot -w update image whatever the image name is.

Yes my device is unlocked again, but I still can't get into recovery mode. It just tells me "Recovery Failed" in small text in the upper left hand corner of my N7.
UPDATE:
After unlocking the device again. I used the Nexus Root Toolkit to restore to factory settings and it worked
The Problem: My device was no responding correctly to the toolkit when locked.
Cheers for the help. I'll attempt to root again, hopefully no problems this time If there are I'll be sure to post again!
Thanks to everyone that replied.

For the love of God..stop using the toolkit from here on out.. learn how to use ADB and Fastboot so you can avoid these issues.

So you erased the recovery then wonder why you could not boot into recovery....
You flashed or tried to flash the bootloader. You already had the same bootloader installed and there was no need to do so to try and fix your issue.
You still don't know what you're doing and are back using the tool that lead you to this issues. A toolkit. Learn what you're doing and you wont face this type of silly issue again.

Don't use toolkits. Most people don't have a clue what the toolkit is actually doing so if something goes wrong they aren't in a good position
Its always nice to see threads like these where the N7 in the face of death but in the end with cutting edge medical technology it is brought back to life and healthy.
My wife has a rooted nexus 7 2012 wifi and she unintentionally accepted the ota Android 4.3 update. So of course it unrooted her.
I originally had a hell of a time rooting this tablet using wugfresh nexus toolkit. Took me several days to succeed and the same thing is happening again. My Windows 7 laptop keeps installing the wrong drivers even though I selected the option to disable the auto driver configuration. Also USBDeview never shows the installed Samsung adb drivers yet when I try to install them I am warned they are already installed. It's already been hours and who knows how many retries and reboots!
So even though I'm a newbie I decided to go the Android sdk route.
1. Where do I download the files I need to just root the darn tablet?
2. What do I do next?
Please keep it simple........
Anyone want to walk me through it on the phone?
Thanks
If you are new to using SDK, check this out for a well laid out tut on how to get set up and rooted.
I now have android sdk set up.
What are the commands I should issue to root?
Thanks
now you need to flash a custom recovery then flash a root zip file via windows command prompt...Have you figured out how to interface with your device and the windows command prompt? eg;
-a good first command is "adb devices" and see if it lists your device, if it does your golden...
-then you would issue "adb reboot bootloader"
-once in bootloader you would issue "fastboot flash recovery whateverrecoveryouchose.img"
-then while in bootloader toggle with the volume keys to "recovery" option and press power
-now you will be in your new recovery you just flashed and you can push the zipped root file you chose to the sdcard, "adb push rootyouchose.zip /sdcard/"
-once its been pushed you can flash it in recovery and reboot, and you are now rooted
-this is the latest cwm recovery that you could flash in fastboot as described above
-this would be the root file you want to push then flash in recovery
-this may be of some help, scroll down halfway
Thank you so much for helping. You can't know how much it is appreciated.
-a good first command is "adb devices" and see if it lists your device, if it does your golden...
Got that. It works!!
-then you would issue "adb reboot bootloader"
Worked! Got the Android on his back.
-once in bootloader you would issue "fastboot flash recovery whateverrecoveryouchose.img"
Is recovery image on my pc or the tablet?
Why do I have to indicate the img name here if I will later select it
When I write
Fastboot flash......... Img
I get
Unknown partition 'the image file name'
"error : cannot determine image filename for. '.......'
You need to have downloaded a recovery image, that is what you flash I linked to one on my last post, that file is called "recovery-clockwork-touch-6.0.4.3-grouper.img" so you would issue,
fastboot flash recovery recovery-clockwork-touch-6.0.4.3-grouper.img
"fastboot flash recovery" is telling it to flash a recovery file and "recovery-clockwork-touch-6.0.4.3-grouper.img" is the recovery file in this case to be flashed so, combined its, "fastboot flash recovery recovery-clockwork-touch-6.0.4.3-grouper.img"
I do not use Windows, I use a terminal instead of windows command prompt so I can't be specific as I am not too familiar with windows command prompt. With terminal it is much easier in my opinion but you need to be running nix or Mac OS to have a terminal
OK, still can't get past the final stage in rooting my wife's nexus 2012 nexus 7.
I have the proper drivers installed and it connects fine with my Windows 7 laptop.
From a Windows 7 command prompt
1. "abd devices "
Correctly returns the attached nexus
2. "abd reboot bootloader "
Correctly reboots the tablet

I downloaded the latest twrp openrecovery img for grouper and renamed it (for simpler typing)
" openrecovery-twrp-grouper.img"
However, when I now issue the command
"fastboot flash recovery openrecovery-twrp-grouper.img"
I get an error :
Cannot open openrecovery-twrp-grouper.img
The same thing happened with the clockwork-touch recovery img. That is why I downloaded the twrp img which I am more familiar with anyway.
So, am I missing a step between rebooting the bootloader and flashing the recovery? After the bootloader is rebooted and I get the Android on his back with an empty belly, do I need to do something else before flashing?
Do I need to put the recovery image somewhere special in the nexus file structure?
I'm stuck.
Thanks

OK, still can't get past the final stage in rooting my wife's nexus 2012 nexus 7.
I have the proper drivers installed and it connects fine with my Windows 7 laptop.
From a Windows 7 command prompt
1. "abd devices "
Correctly returns the attached nexus
2. "abd reboot bootloader "
Correctly reboots the tablet

Hi, Anderson2...
If I may throw in my couple of cents...
The recovery.img file to be fastboot flashed (TWRP or CWM, it really doesn't matter which) needs be to stored on your PC... on the same PATH as the FASTBOOT.EXE file. The easiest way of accomplishing this, is to copy it directly into the folder that contains your FASTBOOT and ADB executables.
Where this folder is located on your PC depends on how you have fastboot setup, but it's usually stored in a folder called /Platform-Tools (if I remember correctly). But because I've never bothered myself installing the whole Android SDK (of which Fastboot is a part of) on my PC, I'm not sure of it's precise PATH (ie. it's location) but I think it's somewhere in the Android SDK folder.
For myself, I just maintain a simple folder on the Windows desktop containing the FASTBOOT.EXE and ADB.EXE files and a few necessary Windows .DLL files. When I wish to fastboot flash a Custom Recovery, I simply copy the Custom Recovery .img file (TWRP or CWM) into this folder, rename it to recovery.img (renaming it thus makes typing at the command prompt easier, and reduces the scope for potential typos)... boot the Nexus 7 into the bootloader, hook it up to my PC via USB. And then open a command prompt on the folder, and run...
Code:
fastboot devices
This is purely diagnostic, and hopefully confirms a working fastboot connection.
You should see something like this...
Code:
025d2d424bxxxxx fastboot
A serial number followed by the word fastboot. If you see this, you can go ahead and run...
Code:
fastboot flash recovery recovery.img
(This command assumes an unlocked bootloader... indicated by an unlocked padlock symbol under the Google logo upon boot. If it isn't, you should unlock it with fastboot oem unlock BEFORE fastboot flashing the Custom Recovery).
My point is, though... the 'recovery.img' to be flashed must be in the same folder as the FASTBOOT.EXE file, or as you have discovered, you will get the error "Cannot open recovery-twrp-grouper.img".
If fastboot can't find it.. it can't open it.
Hope this helps.

Thank you very much! That is very helpful. I had assumed the recovery img should be on the tablet. No wonder fastboot could not find it! I'm sure that will solve my problem.
Thank you for helping. I'm slowly learning my way around the adb, fastboot commands as I'm sure I'll need them again when 4.4 unroots me again.

No, problem Anderson2... glad to help.
Adb and fastboot are indeed powerful and useful tools, and I would strongly recommend anybody wishing to 'modify' their Nexus 7 (everything from rooting to flashing Custom ROMs) to familiarise themselves with the fundamentals of their operation... rather than relying on toolkits.
There are actually ways of flashing TWRP or CWM Custom Recoveries directly from the Nexus 7 itself, without recourse to either fastboot or the need for a PC... by using apps like Flash Image GUI or Flashify. But these apps need you to be already rooted, unfortunately.
So to summarize how to acquire root the old fashioned way....
---------------------------------------
1). Unlock the bootloader first with fastboot oem unlock. For security reasons, this will factory reset the device... ie., WIPE everything on it.
...but I assume your Nexus 7's bootloader is already unlocked, given it's been rooted once before.
And so swiftly skipping forward to step 2...
2). Fastboot flash a Custom Recovery (CWM or TWRP) with fastboot flash recovery recovery.img... where 'recovery.img' is the Custom Recovery of your choice. Reboot the device by using the Custom Recovery's own reboot option.
3). Download Chainfire's UPDATE-SuperSU-v1.65.zip root package directly to your Nexus 7. This DOES need to be on the Nexus 7. Most Android browsers (including Chrome) download stuff to the /download folder on the devices internal storage. You'll need to remember the location, for when you come to flash it with either CWM or TWRP.
4). Boot the Nexus 7 into the bootloader. Although you can do it with adb reboot bootloader, you can also do it manually as follows...
- Shut down the Nexus 7 completely.
- Press and hold the VOL-DOWN button... whilst holding, press the POWER-ON button for about 5-10 seconds. The device should now boot into the bootloader.
5). Boot into your Custom Recovery... whilst in the bootloader, use the VOL-KEYS to navigate to the RECOVERY MODE option, and press the POWER BUTTON to select. The device will now boot into either CWM or TWRP Custom Recovery.... whichever one you fastboot flashed earlier.
6). Now to ROOT!
** If using TWRP... tap on the INSTALL button, and then navigate to the /download folder on the Nexus 7's internal storage, and where Chainfires UPDATE-SuperSU-v1.65.zip is awaiting. Tap on it, and Swipe to Confirm Flash.
** If using CWM... tap on the INSTALL ZIP option, followed by CHOOSE ZIP FROM /SDCARD... tap on the folder 0/... this gives you access to the internal storage of the Nexus 7... from which you can navigate to the /download folder, where again, Chainfires UPDATE-SuperSU-v1.65.zip is awaiting. Tap on NO (the first default option) or YES - Install UPDATE-SuperSU-v1.65.zip.
On every screen in the CWM filemanager (by which you navigate) there is ALWAYS a ++++Go Back++++ option at the bottom of the screen. So you can always backout out of anything. In CWM you can also use the VOL UP and DOWN keys to scroll, with the POWER-BUTTON to select an option.
Once you have flashed Chainfire's SuperSU root package, reboot the device with the Custom Recovery's own reboot option.
Upon reboot, and whichever Custom Recovery you're using , it ***MIGHT*** suggest you are unrooted... and offer to fix root for you. Ignore it, and continue to reboot.
---------------------------------------
And that's it... that's how you root a first generation Nexus 7 (2012).
Hope this is of use and... Good luck.

Ged.

Thank you all very much. I greatly appreciate your help.
This post should be a sticky!
One more question, this nexus 7 2012 is my wife's. But I also own a nexus 7I this one a 2013 which is currently rooted with Android 4.3 and twrp Nandroid backups. I'm afraid that when the 4.4 ota upgrade comes along it might again unroot both our tablets. Are the rooting commands or procedures different for the 2013 nexus 7 (other than using a flo recovery img,) or do I do exactly the same as described above?
Again, you guys are wonderful to help us newbies out. Many thanks to all. Wish I could do something in return.

Hello again, Anderson2...
Well, you sort of are already doing something in return.... you're asking questions.
Questions that require answers. Those answers, whoever posts them, may be of assistance to somebody else. Somebody else looking for a solution to a similar problem.
I always look upon these forums as a means of sharing. Not everybody can know everything. God knows, I don't know everything.... and I've been messing around with Android for three years now. So don't worry so much about it being a quid pro quo sort of arrangement.
I know what I know primarily as a result of my own experiences and what I've learned here from the many (in most cases, more knowledgeable) posters here on XDA. What you learn today, you can pass on to others, tomorrow (metaphorically speaking). We, all of us, stand on the shoulders of each other.
With regard to the second generation Nexus 7 (2013)... I'm afraid I really don't know much about it... but I'd be surprised if rooting it deviated significantly from rooting the first generation Nexus 7....
Namely...
1). Unlock the bootloader.
2). Flash a Custom Recovery.
3). Using that Custom Recovery, flash some SU root package... probably from Chainfire.
Anyway, I've found this tutorial here...
http://forum.xda-developers.com/showthread.php?t=2382051
...and it appears to follow a very similar template.
The Nexus 7 (2013) forum itself, which is also worth visiting, is located here....

I have not been on this site since posting my guide, i do want to let any future people reading this know that, I am not a professional. everything in this guide is using stuff from other peoples threads.... this thread is just step by step directions on how i rooted (and installed TWRP on) MY lg k7 (MetroPCs). Also i had to root before i unlocked the boot loader. Which is not safe, you should probably unlock the boot loader before you root, but i couldn't figure out how to unlock it without root access.
I AM NOT RESPONSIBLE FOR ANY THING THAT HAPPENS TO YOUR DEVICE!
YOU AND ONLY YOU CAN BE HELD RESPONSIBLE

J) in the CMD window type "fastboot devices" - without quotations
(everything is case sensative)
K) then type "fastboot oem unlock" - without quotations
L) then type "fastboot getvar unlocked" if that doesn't work try "fastboot getvar" or "fastboot getvar unlock" to confirm if it is unlocked
(if non of the getvar commands work you did something wrong, and i wont be able to help you, but if you followed the tutorial you shouldn't have any issues as these are the exact steps i took)
M) then type "fastboot reboot"
LEAVE THE CMD OPEN OR YOU WILL HAVE TO REPEAT steps H-I
Step Ten: Flashing TWRP

if the links on that page dont work then use the links here http://forum.xda-developers.com/showpost.php?p=66282525&postcount=42
B) extract the download into your SDK folder on your PC
C) in the sdk CMD window from Step nine
D) type "fastboot devices" - without qoutation
E) ~optional, HIGHLY RECOMENDED~
1)type fastboot "boot twrp-image-3.img" - this will boot up twrp WITHOUT flashing it, just so you can make sure everything is working right
in my case it was twrp-image-3.img check your twrp file name and replace fastboot boot twrp-image-3.img with
fastboot boot INSERT YOUR FILE NAME HERE.img
2)in twrp tap reboot>bootloader
F) when bootloader mode opens back up
G) type "fastboot flash twrp-image-3.img" or "fastboot boot INSERT FILE NAME HERE.img" depending on your file name
H) when finished flashing type "fastboot reboot"
Step eleven
A) follow instructions on step one
B) the reason you must do this is because when you flash TWRP it erases your entire phone and resets it
Congrats you have Successfully Rooted, Unlocked Your Bootloader, and Flashed TWRP, to your LG K7

is this ok with the gapps 5.1 instsall .zip for twrp install or should i use a different? also, do you have a suggested camera app? awesome thread btw. Nevermind simple twrp install fixed everything.
I have tribute 5 and can't access bootloader or install SuperSU.....always fails.
How can I get this to work?
Today backup important files you need!
Is this a real method BC everybody having problems rooting this device so I ask can u make a video and add screenshots
Sent from my LG-D800 using Tapatalk
I can confirm this method works. The only different thing i did was purchase Supersume pro from playstore. Worked like it said it would. The Ls675 is rootable. But no bootloader unlock or bootloader at all for that matter. Im running MS330 with TWRP full root and have twrp backups and fastboot flashable backups via flashfire....

While it does work I can find no method using the buttons to get into twrp all the instructions I find for recovery fail so I can only boot back to it after the phone boots, thus it's worthless at this point. Also the command is fastboot flash recovery imgagename.img and you'll need to remove kingroot from administrators to uninstall.
Anyone else been able to boot directly into twrp from the off position?

Try to do the factory hard reset trick but say no at the second screen. I haven't tried it out yet but I've been reading around several sites and that's a possible solution

I'm no developer by any means but I have Linux and windows on my laptop. I'm familiar with kernel building on bunt and have the source code for MS330 on my laptop. I have a backup of my boot img as well. If you can get to fastboot u can probably flash my boot img if you want me to send it. I have recovery img as well which is twrp. Let me know if you have any ideas on what u need or i can do as far as possibly doing a fresh build kernel later tonight and getting a zImage out of it
Does anyone know a way to successfully root this phone? Not just recover?

Of other interest 5.1 is very dendent on Google apps and move app updates to the system via TB or Link2SD fails more than it succeeds, shows they moved but app inaccessible afterwards hence brick. Mine went down trying to integrate play services and reinstalling from adb didn't help. FYI if you relock the BL it'll lock the phone with a security error too. Moving play services causes unending error screens so you can't really see if it's done moving, but I waited a good 5 minutes before reboot. Issue on fails could have been the system not being r/w. Needless to say backup, backup, backup as I hadn't because I've never had a serious issue doing that and considered it a trivial task. Anyone had good success with integrating updates and cache? Anyone restored from twrp yet?

I'm no developer by any means but I have Linux and windows on my laptop. I'm familiar with kernel building on bunt and have the source code for MS330 on my laptop. I have a backup of my boot img as well. If you can get to fastboot u can probably flash my boot img if you want me to send it. I have recovery img as well which is twrp. Let me know if you have any ideas on what u need or i can do as far as possibly doing a fresh build kernel later tonight and getting a zImage out of it

Can you figure out why we can't boot to recovery via hardware buttons? That's critical for tinkering and testing on the go since I always have my phone but not my laptop for booting into recovery with adb. Not sure exactly where to look, probably start with a search for the words "recovery" and "safe mode" for the buttons and "security error" in the boot.img files.

If your rooted u can dl a reboot recovery app on the play store I have one that works like a charm. But im gonna take a look through Linux at the kernel options using make menu_config and see if there's anything I can see in there.

Thanks again. For anyone that has a soft bricked LG K7 see this man! He brought my S#!? To life through teamveiwer. Thanks again. From my LG K7.
Maybe just my experience, but regarding step 10. I had to have the twrp image in SDK>platform tools, also when you get to fastboot flash twrp-image-3.img, I couldn't get it to work, until I typed it as fastboot flash recovery twrp-image-3.img. Hope this helps anyone else getting errors during this part. Thanks for the writeup.
I need help! Here’s the story. Sorry for the lengthy post. TL;DR at the bottom..
- Was on B32, unlocked BL, TWRP installed, rooted with SuperSU
- Updated to B35, but lost TWRP and root (I don’t know how, but I assume I must have wiped the wrong things? - system? - I’m clearly a novice)
- Now I’m on B35 with an unlocked BL, but despite days of searching and researching, I can’t for the life of me figure out how to get TWRP reinstalled. I want to have TWRP before trying Magisk (have never used Magisk before, but would like to try it this time instead of SuperSU)
- From my Mac, using terminal, adb recognizes my devices.
- “adb reboot boot loader” gets me to a list of options “power off, restart, recovery, fastboot, back to previous page”. Choosing fastboot simply restarts the phone. What should “fastboot mode” look like?
- I tried flashing TWRP via adb while on this page and terminal stopped at “waiting for any device” and did nothing
My conclusion is that I need to downgrade to whatever latest version allows fastboot commands to work properly? Is this B15? If so, is the only available B15 zip the one that is on the ZTE website? Do I just wipe data/dalvick/cache and flash this zip?
Do I not need a Bootstock and Systemstock like @DrakenFX usually posts? That’s how I’m used to doing any updates.
Thank you all for your help, both past and present!
TL;DR: Would like to downgrade from B35 to B15 so that I can install twrp and root again. What’s the best way to do this and where can I find the appropriate files?

I'm not sure where you read all that BS, but if your bootloader is unlocked then you can install TWRP via EDL (Or fastboot if you have it). No need to downgrade for anything :laugh: in the past you would have needed to downgrade in order to unlock the bootloader, now it's not even needed
Download EDL Tool by djkuz and install TWRP with that one. Or you can use axon7tool by tennear, but it's much more finicky and ran entirely by commands (no UI).
And just to avoid more trouble, DO NOT LOCK THE BOOTLOADER! You do that with the system even barely modified and you brick the phone. A bunch of people tried to do something, got scared because they made a simple correctable mistake and just locked the bootloader thinking everything would get restored to stock - doesn't work that way.
Not saying you will do this, but I've seen about 4 or 5 people that started just like you and ended up doing that

Wow, thanks so much for responding to this. Sounds like this should be easy! A couple of questions before I go about following your advice:
1). Do I download EDL Tool to my computer or phone??
2). If I'm downloading it to my computer, does it matter that I'm using a mac?
Thanks again for your help!

Oh, skipped that part. EDL Tool is a .bat. I'm pretty sure you won't be able to run it on a Mac. If you can find a Windows PC somewhere to do this, it'd be much better...
But there's another way.
Issuing "adb reboot bootloader" effectively sends you into fastboot. That list you mentioned is fastboot (if it says "Start" in green, and you can scroll that, it is fastboot). Just use fastboot from the pc: Put TWRP on the fastboot folder on the PC, then issue "fastboot flash recovery twrp.img" with "twrp.img" being whatever the twrp file name is. After that issue "fastboot reboot recovery". And as soon as you are on TWRP, DON'T GET OUT OF IT. Just wipe data, system, caches; then flash a system (e.g. b10 bootstack and stocksystem), then also flash Magisk, and THEN boot to system

"adb reboot bootloader" takes me to the start up screen that says "your device software cannot be checked for corruption..." etc. and gives you 5 sec to either press up or down on volume keys to get to list: “power off, restart, recovery, fastboot, back to previous page”, but the list is all white. If I select "fastboot" it reboots the phone and starts that cycle over again at the "your device software cannot be checked for corruption..." etc page.
Nowhere am I given a chance to use fastboot commands. I'm never on the page with the green "Start".
..This all seemed a lot simpler on my Nexus 5..
Thanks for your help/patience.

I thought you had fastboot since you described the 5 seconds screen and both are very similar. It's normal not to have it though.
I think there's some version of axon7tool for Linux but I'm not sure at all. The best way would be to find a Windows computer.
I wonder how you actually installed TWRP the first time? Via fastboot?
As soon as you get TWRP you should be able to run a few commands to get fastboot back just to have it around.

I have adb and fastboot installed on my Mac and I can't remember how I got it working on my phone in the first place, but I've only ever used a Mac for all this. Terminal recognizes my device and responds to commands until I try "fastboot flash recovery twrp.img" then it says "<waiting for any device>" and does nothing.
Thanks again for the help. I'll keep hunting though. I don't have access to any Windows computer.
Cheers
