[Q] Nexus 7 (4.1.2) can't root

Hi I have a Nexus 7 version (4.1.2 OTA).
I wanted to ask what the deal is or what I'm doing wrong. I purchased the full version of Nexus ToolKit 7. According to the instructions I made the unlocked bootloader and I wanted to root but each attempt failed.
I do not know what I could do wrong when root is fully automated.
PS: I also tried to reflash Stock Rom (4.1.2)
I enclose a picture attachments with an error message

Hi. Yes mam (usb debugging on) have a look to the attachment.
Toolkit me boot into fastboot then reboot then for something to fastboot loaded and back to android and trying to upload the files but nothing superuser is not recorded because of (read-only file system).
have a look on the attachment is there to see everything ...

yep same issue here - problem with the forum regs is unless you have enough posts you can't actually address the issue to the appropriate person can you? Anyway, able to unlock but then is unable to root and rest due to a permissions problem. have tried as administrator but of coure this doesn't make any difference.

You can try flashing CWM recovery and installing Superuser from there.
Download Superuser and copy it to your /sdcard
Flash CWM recovery
Install Superuser from CWM

Profit.

Thanks comminus - but I think that if we could do this then we wouldn't be using the tool kit.

Why not try before you give up? Nothing I suggested is even remotely challenging.
With your tablet booted normally plug it in to your computer and copy the superuser zip in my previous post to the Download directory on your Nexus 7 from Windows.
Judging by the first provided screenshot I can see that option 6 in that toolkit is for flashing recovery. Why not try that?
As far as how to install the zip from ClockworkMod (CWM), there are literally hundreds of threads and YouTube videos that will show you what to do. The better option is to spend a few minutes (literately. It only takes a few minutes.) to learn some basic fastboot commands. If you're willing to learn there are many people who will help.

Thx you for your post
But in the Nexus7 ToolKit can be done but is ClockworkMod must first rename (recovery restore files) but with da only when I have ROOT.
And why unnecessary to install CWM and resolve other problems I'll eat a connection. If "simply" can I ROOT who create me rich enough.

Choose #1 in your first screenshot.
After you install CWM make sure you boot recovery before a standard boot. On rebooting from CWM it will say something like "ROM may flash stock recovery on boot." and prompt with yes or no. Choose yes - this renames /system/recovery-from-boot.p and prevents the ROM from restoring stock recovery.

I'm not really sure what you're trying to say...

I tried quite a few times to root my Nexus 7 with the Nexus 7 toolkit, it hung every time when it was supposed to be installing SuperSU and BusyBox. Every time the last message I saw was "adbd already running as root", and it would just hang there. Everything else appeared to work properly. The only tool I was able to successfully use (more than once) was the Nexus Root Toolkit from Wugfresh http://forum.xda-developers.com/showthread.php?t=1766475. You may want to try that tool.

Oki THX u i try this tool...

I'm also having this same problem but here's my story:
Using the Nexus 1.5.4 Toolkit, I Unrooted + Flashed jzo54k, success. I locked OEM, success. I unlocked again, success. Then I ran the root process again, and it keeps freezing at the android recovery screen. Following the prompt in the toolkit, I walked away for a few hours hoping time would resolve the issue.
If you're wondering why I unlocked + rooted, and decided to unroot, lock, unlock, and root again, its because I'm super-noob to anything android related after version 1.5, I wanted to learn the processes after I found out I was having troubles with certian things after my Nexus 7 updated from 4.1 to 4.1.2

I am having the same issue as you. 4.1.2 is not rooting for me. I can't install CWM or TWRP because it needs to rename recovery files, and to do that you need to be rooted. If I boot in recovery I always get stock

Having the same issue with a stock 4.1.2. I can unlock no problem but I cannot get it rooted. Everything appears to have worked, but it is not rooted. If I revert back to 4.1.1 I can unlock, root, etc. without issue. I was able to root 4.1.1 and use the root keeper app to then update to 4.1.2 and I was rooted still. However, it would not let me install CWM or anything. ROM Manager says it was installed, but booting to recovery always too me to stock.
Any ideas?

Can you point me into the direction to downgrading?

I used Nexus Root Toolkit v1.5.4 and selected the "Flash Stock + Unroot" option. When prompted I choose the default 4.1.1 option and away it went.

To root my 32Gb on 4.1.2 I had to unlock the boot loader, flash the boot loader back to version 3.34, and then I successfully rooted using the nexus 7 toolkit.

[Q] Iam not able to install a custom recovery

Hey, just got my N4 yesterday.
I rooted my device today.
I also wanted to install a custom recovery like cwm or twrp.
But everytime it comes up with the android figure and a red warning.
Seems that every tool kit like the 1.6. nexus root toolkit or the Google Nexus 4 ToolKit is not able to install/flash a recovery.
Am i doing anything wrong?

What you are doing wrong is using a toolkit. Follow these instructions. http://forum.xda-developers.com/showthread.php?t=2018179

I use mskip's Nexus 4 Toolkit without any issues. So far I've used it to root, install clockworkmod recovery and flash the stock image after messing up a build prop edit. Saved me a lot of headaches as I haven't used adb or fastboot commands in over a year, don't even have the sdk installed any more. This is the first phone since I got my Incredible in 2010 that I actually wanted to put a custom recovery on and play with.
Here are some basic questions. Did you unlock your boot loader? Do you have usb debugging enabled? Does your device show up when when your plugged in and booted up into fastboot? Do you have the correct drivers installed? Which recovery are you trying to install and did you try the other one available? Did you use the toolkit to root and did it work?

After you root the device using the toolkit, it is easiest to download ROM Manager or Goo.im from the Play Store to install your custom recovery.
As Ed Daddy said, it's best to use ADB, however, it would save you some times and a few headache if you could just go ahead and download ROM Manager. Sometimes people forget there are *really easy* ways to do stuffs.

While I agree there are "really easy" ways to do things, I was trying to point him in the direction of learning.
Obviously since they don't know how to flash a recovery, they probably aren't familiar with much else.
Learning how to do things properly never hurt anyone.

El Daddy is correct.
Toolkits are silly on Nexus devices, for Nexus the simplest way is flashing via faboot. At the very least take the time to learn from the guide that El Daddy provided a link to. With that knowledge you'll be able to resolve issues like this and help others who get stuck.

Actually I unlocked my bootloader, rooted the device. Using normal OTA 4.2.1
But it seems that every toolkit cannot flash the recovery.
I will try it now with using adb commands...

All the toolkits are are scripts that run the fastboot and adb commands for you, they're nothing complicated and IMO from someone with experience I prefer using them now as I no longer have the sdk installed. Gave up on custom ROMs, my own and others, a long time ago.

Actually it's fastboot not adb that you use to flash recoveries, two different animals. and to the poster recommending ROM Manager, its kind of borked right now and I wouldn't use it to flash anything.
Edit: spoke too soon on ROM Manager looks like Koush updated it and it appears to be working properly. This was the first app I ever bought back in 2010 when I first rooted my Eris and couldn't get clockworkmod recovery to install, the moderators at the time recommended ROM Manager to me to get it installed as nothing else worked.

Yeah, but both didn't work.
I used now the adb commands on my one, still remembering them from my Nexus One, and see it works

For sure fastboot and adb will work. I used it very recently when my n4 updated. Just make sure to download the latest cwm. Had a boot loop the first time as I used an old one. Hehehe
Edit: actually not sure if it was the old fastboot files or cwm that caused the error. Anyway I updated my sdk so everything works well

Actually all the tools booted the phone fine in the fastboot mode, telling me flashing the recovery is fine.
But every time i wanted to reboot in the recovery i got this android roboter with the red alarm...
with the normal adb commands everything was really fine!

You're getting that because flashing custom recovery alone without modifying a file or two generates stock recovery every after a reboot. Go to your /system folder and look for recovery-from-boot.p and rename that to whatever you like then flash the custom recovery again

How do I manually reroot nexus 7??

Ok every guide I looked at said you can easily flash something to gain root again well in order to flash anything you have to have root so it doesn't make any sense and I didn't see any guides on this or related posts and I'm running 4.2.2
Sent from my Nexus 7 using xda app-developers app

fastboot oem unlock
fastboot flash recovery nameofrecovery.img
boot into recovery
flash the supersu.zip root package.
What is so complicated about that?
you dont need root to flash something, you need an unlocked bootloader and a custom recovery.....
i swear the word root has lost all meaning these days. everyone wants it, but it seems so very few actually understand what it is.

Pretty sure you just need to fastboot flash a custom recovery, then you can flash the superuser binaries by chainsdd (Google the package), then install superuser or superSU from the market.
Not familiar with nexus 7, but this is how I rooted a galaxy nexus. There should be a sticky in your device specific forum with links to the process and files.
From my Evo LTE, yup.

Dude,
As the guides tell you, and I lined out above, you need to FASTBOOT FLASH RECOVERY
unless you are already rooted, then downloading ROM Manager or 'recovery manager' from the app store doesnt do any good....
you need a computer to do this in fastboot mode.

Damn I was hoping I could avoid using my friends very slow comp lol
Sent from my Nexus 7 using xda app-developers app

I'm in the similar situation - I upgraded rooted 4.2.1 via modified OTA (original OTA was failing because of one apk) and now I have 4.2.2, but even though I had SuperSU which was ticked to "survival mode" (should keep the root), it apparently didn't. I don't have TWRP anymore, when I press power+vol dn I get the standard "start" screen (original recovery). Also, when I turn N7 on, it is displaying keychain that is OPEN, that means my bootloader is unlocked?
So my question(s)... my bootloader is probably unlocked? If I do the steps:
fastboot oem unlock
fastboot flash recovery nameofrecovery.img
boot into recovery
flash the supersu.zip root package
will I loose all data/apps? I ask because when I first rooted with toolkit, I lost all apps/data.
Also, where to find supersu.zip ? That is different to the installed SuperSU.apk, right?

Damn I can't make ADB work... I tried 2 computers.... Damn google for making this so [email protected]#[email protected]$ .... Constant problems, nothing else. Any clues? I ofcourse, tried kill-server and start-server, no matter what my device is showing offline....
Just checked with my phone (SGNII) and it is working just fine... no clue why Nexus is showing as offline..

TWRP no OS detected HELP!!!

I just installed TWRP on my N4 and have never used it before. I always used CWM and I just wiped it through recovery. My issue is that I wiped EVERYTHING. It says "no OS detected" and won't boot past the Google logo. Can't install drivers when connected to the computer, and I can't for the life of me figure out how to flash a stock image, or fix it with the nexus root toolkit. Could someone PLEASE give me a walkthrough for a noob of how to go about fixing this? I don't understand a lot that deals with ADB and all that. Thank you.

Google tool adb fastboot drivers. Then Google nexus 4 factory image and download that. Use 7-zip to extract it. Flash the flash-all.bat while your phone is in fastboot mode and connected to your pc
Sent from my Nexus 5

Do I she the factory image it originally had which was 4.2.2 or do I use the image I updated to which was 4.3? Don't know if it matters, but I've never done this so I don't want to make anything worse.
Sent from my Z665C using xda app-developers app

If you don't understand, this time right now seems a good reason to learn about it right?
As to you problem, can you boot into recovery..the twrp? If yes, then it is easy. Just sideload a rom (preferably a 4.2.2 rom as it was the last rom on your device). Oh and yeah, sideload does use a bit of adb command (see how important it is for us, the nexus user?).
The other way is to simply use toolkits (which is a shortcut, not good as you will learn nothing of the whole process and it just takes all the fun away). Look in original android dev section for wugfresh toolkits (but I really, really, really hope that you learn ADB. After all, we need to learn to count before we start using a calculator right? ). Good luck. Don't sweat it so much.
p/s: That video there can be used for any android version and any rom of nexus 4.

Sounds easy enough. My only issue has been that I couldn't install any drivers. I can boot into twrp, but that's it. Any guide I've researched says to turn on USB debugging, which I can't figure out how to do since it won't boot past the Google logo, and the drivers won't install correctly when I connect the nexus to a computer.

Use wugfresh nexus root tool kit to flash a stock rom.
USB debugging is not required to flash a stock ROM via fastboot.

The easiest in my opinion would be sideloading a new rom, like cm11, paranoidandroid etc. Then you could easily install it on your n4

I'll try again. I was able to figure the drivers out. Tried flashing a stock image I downloaded, but I still wouldn't boot past the Google logo. I flashed it to the system partition, but I didn't know what partition to flash it to. Do I need to use the modified boot image it wants me to download, or am I supposed to flash it to a certain partition?
Sent from my Z665C using xda app-developers app

FIXED IT!!! thank you all for your help.
For anyone else with this problem, I downloaded "universal naked drivers" and installed them manually, use the Nexus Root Toolkit selected "soft brick, than flash stock/unroot, let it download RETORT and the modified boot image, flash it in fast-food, then when it booted up, re-rooted. (You lose root access when you do this).

[Q] Recovery Mode

Long story short: I want cm on the S4 after using it on the HD+, but CWM isn't booting up.
I've seen problems regarding simply accessing the recovery mode like needing to use the buttons twice after powering on, but the thing is that after getting to do this, for whatever reason, the phone boots up with the default recovery option (Android system recovery <3e>).
Some background on the phone would be that it is rooted, about one year ago when I bought it. I fear that I might have flashed something back then, but I don't have any of the files. To add, I sadly don't remember the method, but I can give some device info:
View attachment 2870784
The next and last thing would be that ROM manager says I have CWM installed and even with the reboot option of the app, it takes me to the default recovery.
View attachment 2870785
Any similar experiences on how to deal with this? I'd at least have a means to access CWM.

Are you sure you're still rooted? If you're not sure I would re-flash root using motochopper

Well, yes. I do have things like tethering and su on the phone, plus root checking apps from the store say its rooted.

ROM Manager is crap. It says I have CWM 6.0.4.7 installed but when I boot into recovery it says 6.0.4.4.
I've been looking for a way to manually install the latest Touch version of CWM but so far I've come up with nothing. Maybe if you flash TWRP (via Goo Manager app) you'll then be able to flash CWM back over it. Sometimes it takes 2 or 3 tries for Goo Manager to successfully flash the recovery.

Even better, I figured out how to flash CWM touch. The loki_tool downloaded here can patch any compatible img file and then flash your recovery directly.

The readme was very helpful.
