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.

[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!

JB issues...Phone, App, or ROM causing the problem??

I've flashed 4 times the Vicious V3 and TR4NSCEND ROM once last night. Each time the ROM works fine and then I reboot it and it goes into bootloop mode. I lose all data and have to reload the OS from scratch. I've followed all the instructions to the letter, and still the JB ROM works for a day or so and then it crashed.
What could be the issue? Is it a phone (hardware issue), one of the appa that I'm using, or something I'm doing wrong?
When I'm retoring the apps, I'm not reinstalling the data, apps only.
Really getting tired of reflashing the ROM and having it crash.
Any help would be greatly appreciated!!
Thanks

At list yours can boot up.. mine just stock in boot loop the first time I flash jb rom it works and I used it for a couple of days and try to flash different jb rom then boom! Boot loop.. I've flash 3 different jb rom with no success.. I'm not new to this stuff I've flash more than 100 different rom since vibrant gs2 and now gnex. I really don't have any idea what happen.. I think one of the jb rom had mess up my gnex. I've I restore to fresh and unbrick state many times and every time I flash jb rom it just stock in boot loop.. I read in some post that I should wait but I don't think 30to 1hr in boot loop is to long.

does it bootloop when boot animation is rolling, or on the google screen?
if it is the first, then connect the phone to adbd, and see 'adb logcat', there might be some useful information there.
if it is the second, there must be something else. do you use an app to reboot? which recovery? if you shut the device down, and power up again, does it still bootloop?
advice: reflash stock from fastboot, flash cwm non touch or twrp 2.1.2, reboot to recovery, flash rom
advice update: use cwm 6.x.x.x or TWRP 2.2.x

long first boot
I am also encountering boot issues. On my Toro Gnex with every ROM I have put on that is Jelly Bean ( vicious, and bug less beast) the first boot just sits at the Google logo. If I do a battery pull and try to start my phone again it boots up within a minute. I will try the log to see what it reads and I will post the results. Is this happening to everyone else where it sits at the Google logo until you do battery pull?

Mine sits at Google logo regardless if I do a battery pull or data wipe on toro galaxy nexus.

Having similar issues - phone will be operational for around 20 seconds, then reboots - but it does not show the Google logo, only the coloured Nexus logo.
Additionally, for me it ONLY happens when WiFi is enabled. Hope this helps someone!

I had this problem on my gnex toro and I managed to get around it by:
Back up any data or be prepared to lose it
Reflash phone to factory 4.0.2 image using GNEX TOOLKIT (google [GNex TOOLKIT V7.4] )
Let the phone boot on stock OS
Download the ROM you'd like to flash on to your phone's sdcard
Shutdown and start on bootloader / fastboot (power + both volume buttons while phone is off)
Flash CWM recovery
Boot in to CWM recovery
Factory data reset
Flash zip from SD card
Reboot and let it load completely
I hope this helps. The gnex toolkit is really helpful and it resolved my issues with getting Vicious and other roms to load

When you say flash cwm you mean flash a zip file of cwm? I've use toolkit 7.4 many times with no problem.. I can restore flash new ics rom.. but when I flash a jb rom any kind of jb rom my phone will be just stock in nexus logo..

[Q] Boot loop after installing incorrect inverted gapps for galaxy s

Hi Everyone,
I couldn't post in the developer section. I've flashed my galaxy nexus numerous times. And now I have a Galaxy S2X. I manage to flash All-Star-Rom v3 no problem. Everything was working. What I believe I did wrong was, I flashed the incorrect inverted gapps from a galaxy S, I did this because I wanted inverted GAPPS, but I didn't realized the GAPPS I got was in the Galaxy S section. I'm now stuck in a boot loop where the S appears endlessly. I can go to the download mode, which I did and tried doing restock Telus rom, which I used numerous times and worked fine using Odin. It goes all the way until the restart and I'm stuck in boot loop still.
I can still go to download mode, but can't go to recovery mode. Any help is greatly appreciated.
Thanks!

*UPDATE* I went in download mode, and using Odin3 v.185 I tried using a known CWM hard recover tar file, and installs it, but it still goes to a boot loop, what else can i do?

You can Odin back to stock. There's a sticky in the development section titled "how to recover from a bad flash."

[Q] Stuck at Google Logo, can only access fastboot

Hi,
there are several threads on this forum dealing with nexus devices that get stuck at the google logo when booting up, however my case is a little different:
I can not even get into recovery.
Here's the symptoms:
The touchscreen became unresponsive. I read that fixing the cache partition helps and it did.
From time to time my device would get stuck at google logo on boot, but i was still able to get into recovery, wipe cache and it would work again. This happened 2-3 times over the course of the last 3 weeks maybe, so i thought its just some minor hangup
2 days ago the device became unresponsive again and i was unable to get into recovery. I have tried several times and once i was lucky to get into recovery (it showd google logo, but when i pressed the power button to turn it off i got into recovery)
now nothing will work. i can get into the bootloader no problem and fastboot is in a working condition
i have tried flashing the factory image using the files provided by google. So far no success
Does anyone know something else to try?
EDIT: aniket0317 suggested using Wugfresh's Root Toolkit which includes a script to unbrick in case of bootloops. That seems to have worked.

Flashing back to stock is a first step, to ensure it's nothing in the software. What do you mean by "So far no success"?

Use Wugfresh's Nexus Root Toolkit. There is a option named Stock Flash+Unroot (Bootloop). The device should be able to get into fastboot mode, though.

This seems to have done it. I have followed the instructions in the toolkit and rebooted the device several times already successfully. The next days will tell whether the touchscreen freezes still happen. But for now, thank you.:good:

Same problem
Hey,
my Nexus 7 2013 has the same error.
Im stuck in Google screen, only enter in fastboot mode.
Tried Nexus Root Toolkit and other methods but stays the same...
In TWRP, touchscreen doesnt work.
What can i do???
Thanks!

Hey thiago,
I don't really know what to do, but I have the same problem now...
I guess it should be possible to somehow boot clockworkmod recovery from fastboot,
but I'm not sure.
I'll mark this thread not solved again -.-

EDIT 2: Yes it worked, at first. Now the device is stuck in a bootloop again. I can boot into team win recovery, but touch doesn't work there so I can't do anything. Booting CWM from fastboot is also not suceessful.

What do you mean CWM is not successful, that there's no touch response? If all else fails, you can use the non-touch version of CWM, using the side buttons to navigate. But I'd be concerned if screen touches are not being recognized.

CWM dont start. Only twrp. Is there a TWRP non touch version?

There's no non-touch version of TWRP that I know of, since its design is based on touch.
What do you mean by CWM won't start? It just freezes? Did you flash the correct one?

Yes, i used this version for Regular N7 2013, but still frozen in the google screen.

I have the same problem.
Stuck on google logo. It boots Fastboot only. It does not boot system or recovery.
What I have done so far:
Unlocked the bootloader
Flashed preview android L successfully But it did not boot. Then i Installed android 4.4.4. Successfully But still nothing. Then i flashed android 4.3 with the same result. Lastly i flashed TWRP to try and flash a zip, but again it does not go past the google logo. Everything i flash goes successfully or at least there are no errors on the logs. I have used wugs nexus toolkit to flash everything. I can see the bootloader version being changed after flashing different android versions, so i can confirm it is flashing bootloader at least.
My conclusion:
I think there is a hardware problem but I don't know how to troubleshoot what is wrong.
If anyone has any suggestion. It will be much appreciated.

What if you flashed the stock factory recovery/ROM, or is that what you mean by 4.4.4 and 4.3? Don't use a recovery to flash the individual .img files, just run flash-all.bat and see what it does.

Yes. I flashed the factory images using wugs nexus toolkit and ticked the option flash stuck + unroot (bricked or bootlooping) to see if it would work as mentioned by OP. All factory images flash successfully all partitions, but it does not boot recovery or system. I tried different android versions hoping it would make a difference and tried booting recovery after flashing each image (4.4.4 and 4.3). I haven't tried typing the command flash all.bat myself to flash the image as you suggested. I've used the toolkit to make it easier. I'll try flashing stock typing command flash all.bat myself and report.
