[Q] rooting and unlocking nexus 7 - Nexus 7 Q&A, Help & Troubleshooting

guys...I am not really a noob, I have experience with many devices, and now I bought a nexus.
yesterday I started my journey with a g-experience device trying to do some stuff with the nexus 7....
I unlocked the bootloader with the nexus toolkit...pretty easy!..but I'm stuck at this point...
I tried to root the device, but the toolkit says that there is no permission for that, then it installs busybox and the operation finishes....
so, the other way is to root from recovery...installed both cwm and twrp but the device boots on the stock recovery, and I can't rename the recovery files because I don't have permissions for that, I can't mount system on r/w...
then I tried to flash via adb comands, but nothing...I can't boot from a temporary recovery, I can't do nothing...
can someone help me please? :good:
EDIT: I solved flahing the old bootloader and rooting with nexus root toolkit.
close this please

[Q] Why no su access after it's rooted?

I rooted my Nexus 7 a few days ago and was able to replace bootanimation. But now I want to replace my new version of bootanimation using Root Explorer, I found I have no super user access (the terminal prompt does not change from $ to # when I type su at the adb shell). The /system is mounted as r/o. I also have the busybox and supersu zip files on the sdcard. Can anyone please tell me what happen here and help me back to su mode? Thanks in advance!!

I can't see any reason why you'd become unrooted unless you either replace the system partition (via an update or rom change or fastboot flash or whatever) or delete the binary yourself. If you didn't do either of those it could be either a problem with supersu, a problem with the binary, or a problem with your kernel. Try putting the root binary (su) back on the phone and trying again, and if that fails try using SuperUser instead of Supersu. If neither work you may need to do a factory reset and try again.
did you upgrade to 4.1.2? You must have lost root during the process. Just re-root it. I used the toolkit.

oh, yes!!!! I just upgraded a couple of days ago from JRO03D to JZO54K. THANK YOU!!
I tried re-rooting again (w/o flashing custom recovery) after I upgrade Nexus Root Toolkit to v1.5.4 t support 4.1.2, But get stuck at the message "waiting for your device to finish booting back up." Nexus 7 is at the TWRP mode and can't get out of it. So I reboot to bootloader mode and eventually the toolkit tells me to run SuperSU and Busybox. Still doesn't work since I still don't have super user access. What shall I do next? I know there are still few more steps after the TWRP.

[Q] Nexus4 stuck on Google Logo, won't boot into custom recovery

I have a nexus 4, I've previously been able to root it and I've run CM10 and pac roms on there, with no problems. I've also previously flashed CWM recovery, no problems.
However, since I've flashed it back to stock Android 4.3, I now cannot access any form of custom recovery,
When I go into the bootloader and select recovery, the device shows a green android fella lying down, with a red triangle and exclamation mark.
I have tried to use Nexus Root Toolkit v1.7.2 to flash custom recovery, when it says it's booting into recovery temporariily, the phone just shows the google logo and nrt says "Waiting for device".
I've also tried locking and re-unlocking, no change,
Tried flashing permanent and temporary recovery, same problem.
I've tried things on forums but none of them seem to work...
(USB debugging enabled, MTP disabled... adb sees the device, just not when google logo is showing.)
Also, when in android 4.3, SuperSU says "there is no SU binaary installed, and SuperSU cannot install it. This is a problem!"
Any help?
Thanks
I think the best way is to restore it again to stock. If you are using Windows use Wug's Nexus 4 Toolkit. Just don't forget to back up.
Then Root your phone,
Install Flashify
Download TWRP
Install TWRP via Flashify (root required)

I have restored to stock, that's what I'm running.
I'm using that same toolkit.
I've tried re-rooting the phone, but when it tries to boot to TWRP temporarily, it goes back to the google logo and is stuck there, computer doesnt list it as an adb device. I have to holddown power and reboot, but noting has changed.

No OS Installed Message TWRP but still reboots to system

I just got a new Nexus 7 (2013). I did all the OTA updates until I got on the latest 5.1.1 (LMY48G). I was able to unlock bootloader using Wug's Nexus Root Toolkit. I then tried rooting using the same tool but the process would freeze once it reached the step of temporarily booting TWRP. The window timed out while waiting for device. The tablet did boot to TWRP recovery. However, when I went to reboot to system from TWRP, I got a message saying No OS installed. I was able to reboot back to system despite the message.
At this point, I used Wug's tool to Flash Stock + Unroot. I then tried using CF- Auto Root which worked fine with me. I was now rooted but when flashing to recovery, I got the dead android. I tried downloading TWRP app from Google Store to updated recovery through that method. I did get TWRP flashed but again I still have the No OS Installed message when going to reboot. Finally, I used use Wug's tool to delete TWRP and go back to stock recovery (dead android). Then I tried flashing TWRP through Wug's tool but ended up with same result of getting No OS installed.
Any ideas why I would be getting this message when I am able to reboot back to perfectly working system? Has anyone else experienced a similar problem and been able to get TWRP working correctly?

HELP - Installing Custom Recovery and rooting with bbqlinux live

Hello XDA,
I need some instruction on how to root and install cwm recovery on my nexus player. I’m currently trying to achieve this with a live boot of bbqlinux for sdk support. I managed to unlock the bootloader. I tried to gain root by installing SuperSu from the app store, but no dice. If anyone can give me insight on what commands/directories/steps needed to accomplish this, it would be greatly appreciated. Also, I have all the files I need on the internal storage of the device.
Thanks
UPDATE - Bootloader is unlocked. When I try to boot the root.img, i get a softbrick and sent back to the bootloader. USB Debugging and unknown sources on.
UPDATE - I was unable to gain root privilege with the stock rom. Soo, I flashed cm12.1 N. Took two flashing, but it lives.

Motorola Moto X pure stuck on bootloop after failed root attempt, HELP!!

Hey everyone I just recently got a Moto X Pure with TWRP recovery already installed and the bootloader unlocked, unrooted. The phone was stuck on Marshmallow so I went to update and it would take me to TWRP recovery every time and when I reboot back into the system, I'm still stuck on Marshmallow. So I downloaded an app that would make me download OTA updates while still having TWRP recovery but it needed root access, which I didn't have. I tried all of the one-click root apps but non worked then I stumbled across an easy root method: ( oops it said I can't post links, but basically I downloaded a supersu zip and flashed it) which I followed very precisely and I'm pretty sure I did nothing wrong. But when I flashed the ZIP using TWRP and booted back into system it was stuck on the Motorola logo which I'm assuming is bootloop. I was going to download a stock recovery using fastboot but I discovered that it would relock the bootloader, which would render the device useless to me so I can't. I also tried wiping the Dalvrik Cache but it always failed. I'm new to all of this so please guys I'm desperate for help. Thanks in advance
You can flash with fastboot the newest stock(the same version or upper) without commands "...oem..." at start and the end.
Or
The newest downloadable without commands "..oem, bootloader, gpt, oem...". @Philo0o
BL will be still unlocked.
Do you have a tutorial on how to do that please?

More accurately you need to flash boot.img which is the kernel , in the case where root was being installed using systemless mode.
Otherwise, if you tried an old SuperSU version (where systemless didn't existed or the ones that failed to detect to install using systemless method on this phone) you'll need to reflash the whole system partition (using Firmware system chunks or custom ROM zip file).
