Rooitng the Gnex

Hi,
I bought the GNexus a month ago, its my 1st android device. (I had a Blackberry for the last 3 years).
I have unlocked my Gnex, and rooted it, then i have installed yakju in order to get rid of my yakjuux ROM, it was my 1st time doing it... Everything worked fine, all my apps were automatically redownloaded and reinstalled from my google account. (Very nice feature).
But for some reason now, I have lost my root acces and I am not sure why or how.. is it normal? I have installed root checker, and supser user returns messages saying he cant get root privileges on my phone.
I tried rooting the phone using superboot. Everyting seemd to have worked fine:
C:\Nexus\r3-galaxynexus-superboot\r3-galaxynexus-superboot>install-superboot-win
dows.bat
C:\Nexus\r3-galaxynexus-superboot\r3-galaxynexus-superboot>fastboot-windows.exe
boot boot.superboot.img
downloading 'boot.img'... OKAY
booting... OKAY
The phone reboted but stayed at the Google logo for like 3 mins. I pulled the battery and after that the phone rebooted normally except superuser cant access root.
Any tips or help is welcome on how to root the phone (already unlocked)
Thanks

You should have left it on there! Mine got stuck on the Google boot logo for around 10 minutes before it was done? I was just about to pull it before it booted up. Go through the process again and give it time

Go on YouTube and look for zedomax. He has an easy root video with a link to all the software

when you installed the yakju ROM to change yakjuux it deleted root because you fully wiped your phone for a yakju build. just reapply superboot (or install clockwork recovery and flash su.zip that will give you root) and you'll have root.
either that or flash a custom ROM with clockwork recovery and you'll have root.

Another thing is always make a backup of your current favorite rom before flashing anything. I have my original rom and 1 favorite rooted rom on backup at all times. If you do this and encounter problems you can always go in recovery and restore your custom rooted rom. The only reason I keep a stock rom on is in case I have to return the phone. You can remove your unlock symbol by going in fastboot and typing (fastboot OEM lock) I think! This was how I locked my bootloaders back up on my beloved nexus s, good luck and pm me if you need anything

Didn't know about su.zip option in CWM, where can I find this zip file for the GNex GSM?

I gave it like 30 mins and still the Google logo was displayed. It seems my rooting did not work properly. Maybe i am not using the right tools?

Zedomax has a nicve procedure, but the link to doenload is GalaxyNexusRoot.zip file is dead. I cant use his method..
Thanks for the help.

[ HELP ] GSM Galaxy Nexus stuck on google logo

My galaxy nexus started rebooting 5-10 times a day about two weeks ago and then suddenly stocked on google logo and never booted. It was stock 4.0.2 with no root and recovery and unlock. the phone goes into fastboot and downloading mode, but It doesn't even boot into recovery, and when you choose the recovery through fastboot, It gets stuck on the google logo again!
I flashed the IMM76D for yakju through odin in downloading mode using chainfire's files in this post http://forum.xda-developers.com/showthread.php?t=1586807.
Odin shows everything is going fine and flashes the tar file , but again when the phone is trying to reboot it gets stuck on google logo.
then I tried flashing the ICL53F factory image through fastboot using fastboot command, I downloaded the file from the google site here https://developers.google.com/android/nexus/images , extract it with 7zip and flashed the bootlaoder. radio. and zip file through fastboot, again everything went fine both on the phone and fastboot window, but again while rebootin got stuck on the google logo!
I'm no new to android and samsung devices and flashing process on them, it's more than two years and had phones like moto milestone, sgs, sgs2, Nexus s, and flashing rom on them is one of my habits. I also used to solve my friend's problems with their phones and flash custom roms for them.
it's the first time I see a samsung device doesn't boot after flashing through odin , and the first time a google device doesn't boot after flashing through fastboot went OK!
I'm really out of ideas here and any help is so appreciated
PS: also I dont know if I should post this matter here in Q&A or in development section? so may the admin help me here

[Q] Nexus Soft Bricked after Jellybean (Help Please!)

For those who want to keep it short, this is the short story:
After updating to Bellybean, Nexus hangs on Google Logo. I'm with the stock Android System Recovery but going to factory defaults wouldn't help. I think I need an official ICS image to flash but how to have it copied to my internal SDCard (cache dir)?
Full Story:
I tried to update to Jellybean from ICS on my Galaxy Nexus and at first attempt, I succeded. However, I could not get the phone to work, to I tried changing the Baseband.
No luck with the Baseband so I thought I'd try another Jellybean update and it trhew an error. I tried rebooting and that was it. Only the Google Logo showed up.
The phone only starts to boot mode when I press both volume up and down and Power.
Now the problem is that I don't have a firmware update in my internal SDCard and when I chose to go to Factory Defaults, it still gets frozen with the google Logo.
I think having an old ICS Firmware in the cache path would help but how to get it there?
Thanks for your help in advance.

Fastboot CWM or TWRP recovery, then boot into recovery and adb push a rom to /sdcard

Why don't you flash recovery from your PC, so you can restore latest CWMR or TWRP created backup?

Download the galaxy nexus toolkit. It will have an option to flash you back to stock

And this is what happens when newbies using XToolkits. Seriously. They can make life easier for experienced users (although i prefer doing everything manually), but Android newbies really should know the basic ADB commands and what to do in cases when phone won't boot up.

Thank you for your response.
Trying your suggestions. Fingers crossed!
Edit: It worked! Thank you so much!

Toolkit mess-up, now I need your help!

I'm not new to rooting on Android (have been doing it since the Sprint Evo) but I think I've seriously messed up this time
I used the Note II toolkit to gain root access (option 92 build AMA7) and then flashed CARBON-JB-v1.7-l900.zip, along with gapps. I wasn't a fan of Carbon and went to back to the toolkit to flash stock and go back to being unrooted. Here's where I messed up: I used option 7 (unroot, uninstall busybox and recovery) thinking that it would flash a stock image too.
The phone boots back up in carbon, so I go back into the toolkit and use option 2 (flash insecure boot, image, root, busybox, rename restore files).
Now when I try to boot up the phone, it show the Samsung logo and goes blank. My computer will not recognize the device through adb, the toolkit, or Kies. I AM able to get into download mode and recovery mode (TWRP 2.4).
I'm not sure where to go from here, this is why I need your help. I tried a factory reset but that did nothing. Any advice.

Look for rwilcos thread. Download a one click to your computer. Then flash it to your phone.

Dusting off the Nexus 7

So I decided to finally turn on my Nexus 7 after a year of no use. It's on 4.4.4 or something and I tried downloading the latest cleanrom and flashing it via TWRP recovery al;ong with the bootloader. It seems to softbrick - The Google logo pops up and it keeps repeating that until I power down the device and boot into recovery.
How do I update my Nexus 7, while keeping root from lollipop to the latest version, marshmellow?

using nexus root toolkit to fix

thanks bud, using wugs worked
