Yes.
An 'exploit' has recently become available for ROOTING the Nexus 7 without unlocking the BOOTLOADER.
This 'exploit' works... I have tested it myself.
Until recently, I believed that because FASTBOOT wasn't an option (as a result of a LOCKED BOOTLOADER), there was no way of FLASHING anything.
Happily, I was disabused of this notion by bftb0... and I can confirm, you can indeed install CWM (or TWRP) with a locked BOOTLOADER.
-----------------------------
Here's how...
First, you need to run this 'exploit' to acquire ROOT.
Upon reboot, you should now be rooted, with Chainfires SuperSU package and associated SU binary installed.
It's important that you are ROOTED before you proceed.
Next, get Android Terminal Emulator from PlayStore.
Download a CUSTOM RECOVERY .img of your choice... either CWM (Both 'Grouper' and 'Tilapia' variants are available)...
...or TWRP for 'Grouper' (N7 WiFi) or TWRP for 'Tilapia' (N7 3G).
Rename it to recovery.img... and copy it to the root of the Nexus 7's internal storage (emulated SD card).
In Terminal Emulator, run the following command...
Code:
su
dd if=/sdcard/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS
Upon completion of this command, shutdown and reboot your device into the BOOTLOADER, and from there, boot into your CUSTOM RECOVERY... in pretty much the same way had you FASTBOOT FLASHED it.
-----------------------------
You are now free to flash whatever ROMs or kernels you like.
However, a word of caution... because the BOOTLOADER remains locked, FASTBOOT is strictly off limits; it simply won't work.
So the first thing you should do after flashing TWRP or CWM is...
*** MAKE A NANDROID BACKUP ***
If the device becomes 'wedged/bootlooped' as a result of some ROM flash gone wrong, then you will have no choice but to unlock the BOOTLOADER (with full wipe) in order to fix it.
But if you have a NANDROID backup... piece of cake... just restore.
-----------------------------
Credits and kudos must go to XDA members, nhshah7, who made this 'exploit' available and bftb0, whose post pointed me in the right direction, with regard to the 'dd' command.
-----------------------------
I can confirm all of this works... my Nexus 7 is currently rooted, running a custom recovery (TWRP), with a custom ROM and Kernel (see sig) installed - all sitting behind a LOCKED BOOTLOADER.
...no Factory Reset (wipe) required...
...and no Unlocked Padlock Symbol upon boot.

Previously I installed cwm and can boot,just 1 time.
I tried to boot into but nothing.
What to do?

This is really peculiar... I had a few problems myself, initially... but I just assumed I made a typo mistake in TE - but I never had a "no command" message. It took me two or three goes before I got it to work.
And it works fine now, without problems.
I recall reading, a while ago, you had to delete a file from /system called recovery-from-boot.p after flashing a custom recovery in order to get the custom recovery to stick. I never had to do this myself, maybe 'cos I'm running a custom ROM.
Are you on stock, or running a custom ROM?

Have you tried running the dd command again?... As I previously mentioned, it took two or three attempts, before it 'stuck' on my N7.
Now I have no problem booting into TWRP... similarly, I have tested this procedure with CWM - and again no problems.
With a root capable file manager, you could try deleting (or renaming) the file recovery-from-boot.p which can be found in /system, and then try again.

Shut down the tablet completely.
Press and hold the VOL DOWN button... whilst holding, press the POWER button.
This will boot you into the BOOTLOADER.
Using the VOL buttons, navigate to RECOVERY.
Press the POWER button to select.
Rgrds,

Just tested this method... again... (using dd to install a Custom Recovery)... with both CWM and TWRP... and in both instances, the installations survived a reboot. So I'm puzzled why there seems to be a problem here.
---------------------------------
I have semi-automated the process in order to avoid typing long complicated commands into Android Terminal Emulator. A process, which, by it's nature, is subject to typographical error.
Here's how...
Download the Custom Recovery of your choice to your Nexus 7.
Rename it to recovery.img
Copy it to the root of the emulated SD card (internal storage).
---------------------------------
Download this script file...
writerecovery.zip
Unzip and copy it to the root of the emulated SD card (internal storage).
(Alongside the recovery.img).
---------------------------------
Install Script Manager from Google Playstore.
Open Script Manager and locate the script file writerecovery.sh on the root of the emulated SD card.
Press ENTER on it...
Select OPEN AS... Script/Executable...
Select SU (root) from the toolbar...
Select Run...
The script will now execute the following command...
Code:
dd if=/sdcard/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS
...writing the recovery.img to the recovery partition.
See attached thumbnails for the sort of thing you should expect to see.
---------------------------------
I have tested this method several times... switching between CWM and TWRP. And performing multiple reboots, to ensure that the Custom Recovery 'stuck' in each instance.
---------------------------------
Hope this works... if it doesn't... then I'm at a loss to explain why.
Maybe somebody with more technical knowledge can assist.
All I know, is it works for me... on my Nexus 7.

well i installed recovery using goo manager ,.,. got this response from other thread and is working for me ,.,., goo manager also has the option to restart in recovery so really good for me
Help with my Condition
OK, I need help with the following Scenario with Nexus 7 2012 Wifi
My USB Port is damaged. Managed to charge batter with external wires. After that I was able to:
> Root my Nexus7 with KingRoot app (several tries does the trick)
> Install CWM (non-touch) with ROM Manager
> Boot into CWM and do a dummy Flash of Update-SuperSU.zip file just to see if it works on Locked Bootloader. It was successful.
Now I came across your thread, What I need help with is:
WILL I BE ABLE TO FLASH A CUSTOM ROM + GAPPS on a Locked Bootloader via CWM ?
This is going to be a one way ride for me, if I brick I have a paperweight.
(I have however a Backup from CWM, which I can restore if the tablet manages to boot into CWM after bricking)
Need assistance, opinions, strategy with this. Response Awaited.

Yes, you should be able to.

The bootloader lock state is irrelevant when it comes to flashing stuff via a Custom Recovery (such as CWM or TWRP).
All an unlocked bootloader does, is it allows the device to accept fastboot flash commands from a connected PC or Mac, and which is the usual way of flashing a Custom Recovery, and then subsequently rooting it.
I would, however, advise against using CWM. ClockWorkMod Recovery is old and hasn't been updated for quite some time, and may cause problems.
Instead, you should take a look at TWRP (TeamWin Recovery Project). This Custom Recovery has a better user interface, and is less likely to cause you problems.
---
Although your bootloader is locked, you have managed to acquire root via KingRoot... which means you can flash a Custom Recovery with the Flashify app...
https://play.google.com/store/apps/details?id=com.cgollner.flashify
This app allows you to flash Recoveries and Boot images (stock and custom) directly from the device itself, providing the device is rooted. The free version of Flashify has a limit of 3 flashes per day. This shouldn't be a problem though... Custom Recoveries aren't something you generally flash on a regular basis.
(See my attached screenshots for a flavour of how Flashify works.)
---
You can find the latest version of TWRP for the Nexus 7 WiFi model here...
http://techerrata.com/browse/twrp2/grouper
Download to your Nexus 7, and use the Flashify app to flash.
And then download whatever Custom ROM+GAPPS you like, and flash via TWRP.
Incidentally, the NANDROID backup you've already created with CWM is NOT compatible with TWRP. So you'll need to create a new NANDROID backup, should you choose to flash TWRP.

This is possible, because you don't have access to fastboot (due to your broken USB port) you won't be able to fastboot flash back to Google Factory stock should you not be able to boot Android (for whatever reason) after flashing some Custom ROM. But providing you have a NANDROID backup and a Custom Recovery (CWM or TWRP) installed, you **should** be able to recover from softbricks such as bootloops. But having said that, I would tread carefully.
Hope this helps, and good luck.

Hey guys,
I had installed TWRP on my Nexus 7 when it was on 4.2
Then updated to 4.2.2, and everything worked perfectly.
But now few days back, I updated to 4.3 and since the update, TWPR has stopped working.
When i go in recovery i get "!" marked Android (Photo attached).
Pls help, what should i do ?
EDIT : I have also tried flashing (through fastboot) new versions of TWRP, still no Luck !!
What you are seeing is stock recovery. You need to flash a new version of twrp
Sent from my iPhone using Tapatalk
The update flashed the stock recovery into your N7. Make sure that your bootloader is unlocked and flash TWRP through fastboot, with "fastboot flash recovery [thenameofthefile].img".
Pls read the post guys, I already tried flashing new twrp, it didn't solve the problem, that's why have posted!

Hi, Nikhs...
That's kind of odd... never had any problems myself using fastboot flash to flash a Custom Recovery.
Are you sure you have a working fastboot connection? Type fastboot devices at the command prompt to confirm this. You should see a serial number, followed by the word "fastboot" (without the quotes)... something along these lines...
Code:
025d2d424bxxxxx fastboot
If you don't see something like this, then attempting to fastboot flash anything is a pointless waste of time. You could have a driver problem, ubiquitously known as 'driver hell'. This need to be resolved before you can proceed.
If fastboot flash still fails to flash TWRP, then I'm out of ideas... the only other solution I can suggest is you try flashing the TWRP .img file using either one of these two apps; Flash Image GUI or Flashify. (The TWRP .img file to be flashed will need to be either directly downloaded to the Nexus 7, or copied over to it first).
Both are pretty self-explanatory to use... just follow the on screen instructions.
I have successfully flashed both TWRP and CWM .img files in the past, using these apps, on my Nexus 7, without problems.
Although I've never used it myself, I understand that GooManager will download the most recent TWRP .img file, and automatically flash it for you.
However, the problem with all these apps is... you first need to be already rooted for them to work. So if you're trying to install TWRP in order to initially gain root access, then these apps won't be of much use to you, unfortunately... in which case, you'll have to persevere with fastboot, and see if you can get it to work.
fastboot flash recovery recovery.img should work though, and (barring driver problems) the only thing I can see preventing you from successfully flashing a Custom Recovery is a partition corruption, or some sort of underlying hardware problem.
On a final note, (and clutching at straws a little here), try a different USB port or USB cable or even a different PC (if you have one). Tech can be bizarrely capricious at times, and sometimes something as seemingly trivial as changing to a different USB port can resolve the most intractable of problems.
Hope this helps... and good luck.

thanks for the help !
Problem solved,
I installed the Same version (Old version) of TWRP as i had before upgrading to 4.3
then installed the latest version of TWRP over it.
Seems like that solved the problem..
I wonder what and why and how it solved
OK, I see that this subject has not been properly addressed in this forum and there are a lot of users who still use tool kits,etc. for this. That's fine but you're missing out on how to more effectively manage your device. I'm writing this off the top of my head, and on my n9 which is not so easy, so I may modify it in the future.
The first thing you want to do is learn how to use fastboot. Fastboot allows you to flash image, .img, files on your device. If you've never done that start here, http://forum.xda-developers.com/nexus-9/general/guide-how-to-unlock-bootloader-flash-t3035153
Rooting is as simple as flashing a custom recovery on your device and then booting into that recovery and flashing Chainfires supersu.
So how do you flash a custom recovery? Well I strongly recommend twrp. Download the latest from here, https://dl.twrp.me/flounder/ I always find it easier to rename the file you download to simply recovery. Make sure you maintain the .img file extension. Download this onto your pc and remember what folder you downloaded it to.
Then download the supersu.zip file to your device. Download from here, https://download.chainfire.eu/696/SuperSU
Now you're ready to get started. Boot your device into the bootloader and connect it to your pc.
On your computer open the folder where you downloaded the twrp image. On an open area in that folder shift, right click on your mouse. You should see a pop up and a place to "open a command window here" In that command window type, fastboot devices. If you see your device's serial number you're good to go to flash the twrp image file.
OK, the Nexus 9 is not as easy to root as other Nexus devices. So start by typing, fastboot boot recovery.img. (Remember I told you to rename the twrp image file to recovery, if you didn't do that use the full name of the twrp file you downloaded for recovery.img) Once you boot into twrp go to install and find the supersu.zip you downloaded onto your device. Install it.
Then from twrp, boot back into the bootloader.
Once booted into the bootloader open a command window in the same folder as you have the twrp image downloaded. Then type fastboot flash recovery recovery.img
You're now rooted and have twrp installed.
Having major problems trying to do this on Marshmallow, lol.
This no longer works as described on 6.0. I can get you rooted but I can't get twrp to work properly. It doesn't decrypt the device. But you'll need a usb stick.
To the usb stick copy flar2's elemental x kernel, http://forum.xda-developers.com/nexus-9/orig-development/kernel-elementalx-n9-0-02-alpha-t2931657. Also copy supersu, http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133
Boot into twrp:
fastboot boot twrp.img. Use twrp 2.8.7.0 and the full name of the image file
When you boot into twrp hit cancel. It'll boot into twrp but won't decrypt your device. In twrp go to mount and mount your usb stick. Then from twrp flash the elemental x kernel. Then flash supersu.

Thanks, that worked.
I went and installed Busybox, not sure if I needed to?
I really want to get this thing decrypted now but am happy to wait for a Marshmallow solution rather than go back. I suppose I could flash a ROM without forced encryption from the flash drive too? As long as I do a full wipe?
I only got my N9 a week ago and haven't had time to play with it so all this encryption stuff is new to me.
---------- Post added at 09:08 PM ---------- Previous post was at 09:04 PM ----------
I am rooted but can;t copy hosts file over, system is read-only, is this an encryption thing or has something gone wrong please?
---------- Post added at 09:28 PM ---------- Previous post was at 09:08 PM ----------
One more question..
If I was to factory reset and then flash the kernel and supersu would I get an unencrypted device? Or if I hit the "decrypt data" button in the "wipe" menu in TWRP? I am scared to press it, lol.
Excuse me but this only adds confusion in case of 6.0. So far the most comprehensive guide I found here is this one (see also an answer there).
That solution involves wiping data, so you need your stuff backed up somewhere. In my case I restored playstore apps from google account and just reinstalled the rest from apks.
I answered my own questions here http://forum.xda-developers.com/nexus-9/help/decrypt-marshmallow-question-t3222592. Thanks again for the help jd1639.

For N (and MM in some cases), you need systemless support - which the current version of SuperSU has. (Magisk 12.0 has it as well.)
Where Magisk (vice SuperSU) has advantages is being able to hide that you're rooted (Android/Samsung Pay, Visa Checkout, SafetyNet, etc.) - which is, in fact, why I am evaluating Magisk.
So far, I have seen next to no disadvantages to N - even on "moldy" SoCs (such as the TI OMAP in my Galaxy Nexus - the oldest hardware I've heard of - let alone seen - running N on a daily basis; I run N as a daily driver). I even prefer N to MM, let alone anything older, on the selfsame GNex (which utterly flies in the face of "common wisdom"; it makes me wonder, in fact, if "common wisdom" is a coverup for "fear of change", since said "common wisdom" predates Android by several years).
Hi,
Isn't is required to unlock bootloader first ?
Where this unlocking is done in this procedure ?

Yet, I noticed in many threads of rooting in mediatek devices, that just flashing recovery.img and boot.img is the 1st procedure to make the device root.
Does it mean that mediatek device does not require unlocking the bootloader ?
Thx
Hi
Earlier today I was running 7.0.0. Stock No root with unlocked bootloader, all of a sudden random reboots. Until it no longer wanted to go past Google screen. Plugged into nexus root toolkit, tried flashing stock, downgrading to marshmallow, locking bootloader, unlocking again, multiple times and tries with no luck. The device now will only allow me to get into bootloader when I plug it to charge and immediately press power & -volume. I would appreciate it any help I can get in this.
Thanks

Just about everyone in this thread is in similar boat. I think there is one that was on 6.0, but most on npd90x I believe. There might be something useful to help you with. What version of twrp are you using? 3.0.2-1 has a bug with efs partition.

You mean flash to install TWRP or you were trying to install via ADB and your phone wasn't in recovery? You flash the TWRP image to install it from your bootloader via fastboot commands. You can load other files onto your phone via ADB sideload while in recovery. It is helpful to be clear on the forums so people can better help.

You mean flash to install TWRP or you were trying to install via ADB and your phone wasn't in recovery? You flash the TWRP image to install it from your bootloader via fastboot commands. You can load other files onto your phone via ADB sideload while in recovery. It is helpful to be clear on the forums so people can better help.

I had been trying to install twrp onto my phone through the toolkit, using the "root and install custom recovery option" but then it got the error and cancelled.

Again, without knowing what you have/haven't done in advance, it's hard to be of much help. To run ADB commands, you need to have USB debugging enabled on the device from settings. So, if you haven't done that, you can't do anything via ADB/fastboot and prior to that, I see you said you did have an unlocked bootloader.
Beyond those two things, which are reiterated within it, I'd strongly recommend following Heisenberg's guide at http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928 to do any flashing on your phone. This begins by ensuring you get a working version of the drivers installed to your machine via the Android SDK. Since your BL is unlocked, you should be able to flash TWRP via fastboot command. Also, ensure you are installing version 3.0.2-3, the latest 'unofficial' that is bug-free.

Just about everyone in this thread is in similar boat. I think there is one that was on 6.0, but most on npd90x I believe. There might be something useful to help you with. What version of twrp are you using? 3.0.2-1 has a bug with efs partition.

Hey again
I used guide specifically to go back to stock, combined with a couple times of wiping in stock recovery I finally got the phone to boot up! However I've learned something new, the phone will only stay on if I'm plugged into charger, and as soon as it's unplugged it turns off. Any other suggestions?
So this morning I got an update to fix the voLTE bug. I'm unlocked with twrp installed and rooted. Just for the sake of experimenting I tried installing it. Well that didn't work. Just gets stuck in twrp recovery and you have to power the phone off completely to get it to boot. I guess my question (even though it's a little early) is there a way to install the update without reverting back to stock?
EDIT: Link to the zip

I don't believe so.
In the past you either had to go back to stock or wait on someone to create a compatible update for rooted devices.
Can you post link to zip?
If you are rooted, you can find the zip in cache folder in recovery.
Can you add what variant and build you are using before the update? Also the build afterwards?

I got the update, but all I see on my magisk rooted G5+ in /cache/recovery are log files and the fstab files. Anywhere else to look?

Yeah I can't find anything in that folder either.
I received the update and applied it. I am not rooted.
I have the XT1687 model.
My current build number is NPN25.137-35
My device BL unlocked, TWRP installed and rooted with magisck.
I'm getting the update notification and splash screens several times daily.
Anyone rooted try installing the update with Flashfire app?

If you have systemless supersu, you should just be able to apply the update after reverting to stock recovery.
So I found where the zip downloads. I wonder what flashing it in twrp would do?
EDIT: Here's the link to the zip and I've put it in the OP.

OK, so I tried flashing recovery.img from stock firmware build 33. But the OTA update will not install, instead I get an error after downloading and rebooting (red triangle at recovery mode).
So I tried fully reverting to stock firmware but I decided to skip over erasing userdata. Afterward the OTA downloaded and installed successfully. Keeping userdata does not seem to have caused an issue.
My problem now though is how to get root back without having to wipe userdata after re-flashing TWRP.
Or is this not possible and if I want to root I must first wipe userdata so that TWRP can read internal memory?

Just tried flashing it with TWRP and no luck:
Verifying current system....
E3002: Package expects build thumbprint of 7.0/NPN25.137-35/37:user/release-keys or 7.0/NPN25.137-33/35:user/release-keys; this device has .
Updated process ended with ERROR: 7
which doesn't make much sense since I rooted the stock ROM (Build number reads NPN25.137-33).
If your using a custom recovery flash the stock recovery, then go to the stock recovery and using your computer flash using adb sideboard command. I assume you already know how to do this. Hope that helps.

I'm stuck in the same boat... no idea how to flash the stock recovery and sideboard, what that even means, or if that would break root. I just followed the step-by-step "how to root" video when I first got the phone
There's a workaround to disable the "advanced LTE" or whatever it was called, so I did that. But in the meantime until a more "user friendly" means of updating is available, is there a way I can get rid of this nag screen? Way back on an earlier device (Samsung Charge?) I remember manually editing a "build.prop" file or something to match the latest version so I wouldn't keep getting the software update nag. Is there something that will do the same here, or is there a system app I can freeze in TiB?
My best guess is freezing "Moto Actions 03.022.1.4-N" because it's showing "(updated)" on the side.

What he means is you need to download the stock rom, unzip it, then boot phone to bootloader mode and connect to PC. Then flash the recovery.IMG from the stock rom folder with command prompt:
Fastboot flash recovery recovery.img
Then you can on the phone tell it to boot to recovery mode. This will be a screen with Android on his back and the words NO Command on the bottom. Then plug to PC and use adb command to sideload the update zip like this:
adb sideload [nameofupdatefile].Zip

Strange, reflashed the stock recovery and adb can't see it (adb devices returns nothing). And when trying to install it via the normal OTA way, the stock recovery tries to install but ends with an error.
That's what happened to me when I tried reverting to stock recovery and then trying to install update from phone Settings app.
I ended up having to revert to stock rom to get ota to apply with settings app. But now I am trying to root again but after installing TWRP data is encrypted again. So looks like I will have to wipe data before re-rooting.
