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,
Ged.

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.

[Q] Did I brick my Nexus 4?

Hi,
Last night i was playing with my N4 (with some root applications) and an app asked for a reboot. I just pressed yes so that the phone will reboot (I have done this earlier without any issues). Suddenly the device doesn't boot up. My N4 is stuck at a black screen. While trying to boot up, the Google logo appears and then a black screen. It doesn't advance to the 'X' logo. I'm running on stock, rooted phone (used N4 toolkit by Wugfresh to root).
I'm able to boot into recovery although. I tried all the possible means, wiped cache, dalvik cache, did a factory reset, backed up the system and tried to restore the same. Nothing happened.
Then i tried the "Back to Stock" option in the N4 toolkit and chose the option "Soft-brick/Bootloop" to recover my N4. These are what happened:
Downloaded the 4.2.2 image from Google servers and tried to flash in the device with prior instruction from the toolkit. Everything went fine until the flashing process. In the last step the CMD window opens up saying it is unrooting and flashing stock and immediately it'll bring up a complete message saying the flashing is complete and to wait until the device boots up. But nothing happens again.
I tried the automatic flashing and on the downloading window it saying download failed and hash checks failed meaning its not downloading.
I searched all the possible threads in a day to find a similar problem but in vain. I'm not a noob but i'm too lazy . But i would do anything to bring my N4 back to life. Anyone please show me a direction.
In short:
Status: Soft-Bricked (guess so), black screen after Google logo
Version: Stock 4.2.2 (rooted+busybox+supersu+twrp)
Able to boot to recovering: Yes, bootable to recovery and bootloader.
Tried Nexus toolkit recovery: Yes but in vain.
Gave up: No and never, I'm searching and searching for answers and I'm worried if I'll end up in a hard brick. :crying:
Guys, please help.
Thank You!

I'm just taking a wild guess here - I'm not responsible if anything bad happens, and you might want to wait to someone else seconds my suggestion in any case (although I can't imagine things getting worse as long as you flash N4 stuff). But have you tried flashing a new boot.img/reset kernel from recovery or via fastboot/toolkit?

Err...nope I haven't tried any and will wait until someone seconds you. Meanwhile I have wiped off the ROM through the option in recovery. Still will I be able to do what you said? Also if could direct me to a "how-to" thread would be great. Just that I don't wanna mess up again.

Also, is there a way to transfer a ROM to N4 through fastboot? So that I can install the ROM through TWRP.

No, my suggestion would require that the ROM is still on the phone, so you should restore your ROM prior to my suggestion. And I'm by no means an expert (therefore the disclaimer), but I *think* that since it's a bootup problem, it could be solved by flashing a new boot.img (which is essentially flashing a new kernel to the system).
But yeah, let's see if others think this might help, haven't researched it, is at work right now. Just throwing in a suggestion, that's all...

I *think* (again, I'm totally not sure about this, as I haven't tried it) that you can sideload a ROM via zip file from recovery, but since I haven't tried it I'm not sure - can anybody confirm???
EDIT: Chromium's suggestion is better, by pushing the ROM.zip to the device and flashing from recovery (check md5 first, just in case).

Yes there is. Your nexus is not bricked and this is why you shouldnt use toolkits to do things. This is honestly an extremely easy and simple fix. Use adb to push a rom onto the n4.
Code:
adb push \path\to\rom.zip /sdcard
Boot into recovery, do a full wipe, and flash the rom.

You said you downloaded the Google images.
Just boot your phone into the bootloader and run the flashall.bat that is in the Google image folder.
Note this will probably fully wipe you're phone in the process

Okay, thanks guys. I'm on it. Will let you know when I'm done.

That same thing happened to me once. I had to extract the google file and look for the 4 img files(bootloader, system, userdata, recovery) and flash them with toolkit manually and it fixed it, but it erased everything on my sd

I tried to load the file "occam-jdq39-factory-345dc199.tar" into my phone using the ADB sideload feature in the toolkit. I don't have the SDK installed hence I depended the tool again. But now the tool only loads .zip file and not .tar as the one that i downloaded. Am I doing it right?

K if you have a custom recovery installed, there isnt much you need to do to fix the issue.
First setup adb/fastboot by reading this
Then boot the phone into recovery, and plug it into the computer. Open a new command prompt window and use adb like this:
Code:
adb push \path\to\rom.zip /sdcard
Then you can unplug the phone. From recovery go to the install menu, find the rom that you just pushed, and flash it.

No the tar wont work through recovery. You should download a rom from here or here.

TWRP and CWMR not recognising OS

I am relative new to Android and rooting so bear with me if I am saying the wrong things.
I've just gotten a Nexus 7 (2013, WiFi - "flo") and tried to root it on Marshmallow (MRA58V). I followed all the instructions - installed Google drivers, set up ADB/Fastboot using "Minimal ADB and Fastboot", unlocked bootloader, flashed custom boot.img, and then flashed TWRP (and CWMR) with Fastboot. When I then boot into TWRP, I cannot navigate to /sdcard where SuperSU is placed. When I check the log, it comes up with "cannot mount /boot, /system, /cache..." etc. The same thing happens in CWMR. I've tried to use NRT to root instead and the same problem happens. Am I missing something here? I've even downgraded to Lollipop with NRT and the same thing happened again. How can I not even get TWRP to work?! This is driving me insane!!!
Thanks for your help in advance.

sounds like either one of two things:
1. maybe you are flashing the wrong twrp recovery (is the codename correct? )
2. have you a complete new model? maybe it has a new partition table (wich means you will need a new twrp)
Sent from my Xperia T using XDA Free mobile app

Thanks for your reply. It is a brand new model I guess (bought it a few days ago for black Friday). It came with Lollipop 5.0 out of the box. I did use the latest TWRP for Flo so I guess it must be #2 (new partition tables). Do you know if it is still being developed? Last update seemed to be in July. Also, are there any alternatives? Ive tried the new Cyanogen Recovery which could access /sdcard but wouldn’t recognise SuperSU Zip to install.
Thanks again.

HELP! stuckk at Google logo device is corrupt!

I've posted in a few places here on xda but no responses yet, please help! I've unlocked bootloader, rooted, installed twrp, tried to flash cm13 but had the wrong gapps, so it failed, I tried to wipe and restore a backup I made in twrp but it says my device is corrupt then halts at the Google logo. I think all I need is to push the correct gapps to the phone through adb but I can't get my stupid pc to recognize it anymore. I boot into twrp, plug it in to the pc, tried multiple tools and sdk adb route, but nothing works! I have all the drivers installed, and reinstalled, keep getting a Windows error "The procedure entry point WSAPoll could not be located in the dynamic link library WS2_32.dll"
I read somewhere that the ws2_32.dll is only available in Vista and up... I'm running xp, I wonder if that's my problem. Sorry for all the posts and long explanations, I'm just frustrated and need professional help

You could get that dll somewhere and add it to your windows. I never flashed under Win XP... Also, you could try to download the factory image (NRD90U) from google. Boot your phone on fastboot mode and flash all the .img one by one and should be back to stock... That should fix your problem hopefully!

How do I boot into fastboot mode? I can get to the ko'd android and select options and get into twrp, it says download mode disabled and connect usb data cable, which doesn't change when I plug it in but I see my serial under fastboot in the skipsoft tool kit. I mainly get that error message when using that tool kit too

If you're running XP your pretty seriously out of date.
All of them say download mode disabled when you are in your bootloader. If you see the little droid on his back and the ascii device status in the bottom left corner of your screen you are in bootloader (which is fastboot 'mode' as you put it). Since it is returning your serial number it sounds like you're good.
I expect you may want to simply reflash the stock OS from your Skipsoft kit. Get it booted stock first, then install a custom ROM.

Ok thanks, got my bro here with his win 7 laptop, gonna try and see about pushing the correct gapps to the phone first, if I can't get adb to work when booted into twrp I guess I'll try the fastboot method to stock.
Is it safe to use the Skipsoft toolkit to flash stock Rom while I have twrp installed? And unlocked bootloader?

If your device is currently borked, just start from scratch. If you flash the factory image partitions properly as per Heisenberg's guide then recovery is overwritten anyway. And, you can't flash anything unless your bootloader is unlocked. You would need to reflash TWRP and SuperSU after it first boots.

I would suggest booting it up stock and letting it set up before flashing TWRP and then rooting. And if you do, when you flash TWRP via fastboot, boot right to recovery and flash SuperSU, otherwise TWRP will get overwritten by stock recovery. Rooting stops that.

So you went through that and flashed the wrong Gapps pkg again? I may regret asking but what custom ROM are you flashing? There are really only debloated stock variants right now.

Nexus 6p won't boot up

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.

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?
