[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

[Q] nexus 7 no OS

Wifi model was unlocked and rooted with Franco kernel. Tried flashing stock and getting from 4.2.2 to 4.3 via toolkit and the download stopped got stuck before it took. So it was left with no OS. Tried everything I could that was simple(I'm a total noob) but could do nothing with it to get back to stock. Did factory reset and tried to go that route based on several guides it's worked for others but isn't working for me so far.
Can get to twrp using the temporary boot custom recovery in wugs toolkit. Have pushed a 4.2.2 nakasi zip into the twerp as well as USB drivers zip. They are in 'install' in twrp. The install attempts always fail. Have tried sideload with toolkit,stock recovery etc...etc... It either can't find device or times out waiting for device. Help wold much appreciated,apologizing ahead of time for being a noob who got in deeper than I should have.
Need help anybody have any ideas?

Either you are on the wrong subforum or you are confused what software you should be using. 4.2.2 was never released for Nexus 7 2013 and it is flo or deb, not nakasi, which was previous nexus 7.
As to your problem, you might have better results flashing the factory restore.

[Q] Cannot upgrade Nexus 4 to Lollipop or do a factory reset without USB

This is my first post here because I usually find answers on my own but this seems to be an unsolved issue everywhere so please excuse me if I do not follow a proper format.
My Nexus 4's USB is broken (not the wire, but the actual microUSB) so I can charge fine but cannot connect to the computer. It is unlocked and rooted and I do not mind losing my data (everything is backed up) but I cannot get the update without a PC.
A way to get the update very easily and without losing data was to flash the OTA zip using TWRP 2.7 but it gave me an error saying it cannot install zips from sdcard. So I flashed the latest CWM which can do it but it gave me an error saying "package expects build fingerprint of google/occam/mako:4.4.4/KTU84P/1227136:user/release-keys or googleoccam/mako:5.0/LRX21P/1570855:user/release-keys; this device has google/occam/mako:4.3/JWR66Y/779366:user/release-keys." but my phone has 4.4.4 KTU84P and I know that. I am wondering if it is because of the weird looking kernel I have due to my use of Wug's NRT in the past so I flashed stock recovery to factory reset but when I found out my phone was going to be locked again, I flashed CWM using Flashify again. I'm attaching the screenshot of my 'about' below.
Since I do not mind losing data by flashing a factory image, is there any way I can do it without connecting it to the PC? Because I really want this phone to return to stock? (I know with Flashify you cannot) but I'm apprehensive of locking the phone again because I'd really like to root and install custom recoveries etc.
Thanks in advance!

For the ota to work you need the stock recovery and no system files modified or deterred. I would flash the stock recovery in flashify and try the ota 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.

I followed Heisenberg's guide with no problems the first time, it was all good before I was stupid and flashed a Rom with wrong gapps and tried to restore a backup, thanks tho, I really appreciate the help!

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.
Sent from my Nexus 6P using Tapatalk

Not again, only flashed wrong gapps once, was trying to flash cm13 and got the gapps from opengapps.org. It's ask good now tho, I'm back to stock thanks to you guys and the skipsoft toolkit! Thanks again!
