[MAJOR PROBLEM] Samsung Galaxy Nexus - try to Root the phone, now unusable

I had used "Galaxy Nexus Toolkit V7.7.0 to :
Unlock my BootLoader,
Root my phone
Rename Files Recovery
Flash Recovery (CWM Touch)
Install BusyBox on Phone
And now, i have install the rom JellyBean 4.1.1 with the Recovery Mode :
(I take the Rom here : http://forum.xda-developers.com/showthread.php?t=1737849)
After HAVING done all of this, i try to boot my phone, but he remained stuck on the loading screen (animation) ... even after 1 hours of waiting....
I had go back in recovery mode and I "Wipe" all the DATA, now there is no more operating system on my phone and i'm not able to install a new ROM and i can't even go thru my phone data via USB cauz my computer not recognize my Samsung Galaxy Nexus anymore...
Someone can help me I think I'm in big trouble right now...

This is the problem with toolkits. Things can go wrong and you don't know where it went wrong. See my signature for my thoughts.
As far as getting your phone working again. Follow efrants guide http://forum.xda-developers.com/showthread.php?t=1626895 it has all the info you need to get up and running.

First of all, next time, do not use the toolkit or one-click-root methods. They have more chance of bricking your device than using fastboot commands.
Also, can I ask you which recovery you have right now? Is it clockworkmod or stock?

Ok thanks i try this right now... Hope it will work, i'm freaking out at the moment...

Ok, i'm in big big trouble.
The driver does't find my Device at all. I can't enter in my phone via USB from my PC, so i can't do anything....
They have no more OS on my device, i guess this is why Windows7 dont recognize my phone with any drivers i had try the one from SAMSUNG that have working well for me before i **** up my phone, and now the Universal Naked Driver (http://forum.xda-developers.com/showpost.php?p=20058157&postcount=1) , don't work

Make sure you uninstall any unrelated drivers first. Then proceed with the driver installation.

I have already done this...
I had uninstall the SAMSUNG driver correctly.
And then install the Universal Naked Driver.
Nothing work for me, it's like my phone had no more OS installed, and windows doesnt recognize it.

Boot into the bootloader. Then install the driver.
Your phone should show up as Android 1.0 in your device manage on your PC. Update that.

I've been seeing issues with the toolkits and rooted my phone hours ago using adb, worked flawlessly except the drivers lol.
But after I got that resolved it worked, no jb issues and no other issues. Recovery stuck as well.

Yes, I realize you can't do these things. I gave you the info to fix your problem in the second post.
You need to boot into the bootloader and flash the stock images with fastboot. I don't know how much clearer I can be.

Be patient with rooting, frustration will lead to mistakes.

Ordinarily, I don't recommend tool kits either, but in this case you quite frankly seem like the kind of fella that needs one. SO HERE IT IS. This is a different toolkit than you used before. Be sure to select the correct device first off(because this works with ALL Nexus devices not just one), then do the part entitled "Initial Setup". Do the FULL DRIVER INSTALLATION. It may be that you don't need to, but it will not hurt so do it anyway. After that, click on the "won't boot up" checkbox under "Flash Stock + Unroot" button, then click the button. At all times, read and follow directions. I used this toolkit once, now I do things manually. But you seem incapable. Not intended to be insulting, just a statement of your technical aptitude. Not everyone can do this stuff. So if you have tried EVERYTHING above and been unable to complete any of it correctly, then try this. It isn't one-click and requires some amount of effort on your part. My 11 year old nephew did it though. Good luck.

As El Daddy said, you are not reading the instructions. Your fastboot driver IS installed properly if you see "Samsung Galaxy Nexus BootLoader Interface". Follow the instructions step-by-step. You do NOT need to see anything in "My Computer". It seems like you are panicking, and not reading...

And let's not scare the guy: you CANNOT "brick" your device using a toolkit. There is a big difference between not being able to boot because of a bad flash (not a brick), and a device that cannot boot at all (i.e., a brick).
It seems like people are using the term brick to mean a lot of things other than what it was meant to mean: "bricked" means that you cannot boot your device without JTAG, or sending it in for repair, i.e., it's as useful as a brick.

Ok thank you everyone, sorry about my patience tonight...
Now ma Samsung Galaxy Nexus is on Jelly Bean 4.1.1 with SuperUser and all the stuff and i'm happy
So thanks everyone.

Back to Stock Attempt

Heya, got an issue with a Galaxy Nexus phone. Phone does not seem to get any reception, I've attempted to add the Rogers network multiple times, and still either it says error or there is no reception at all. It is an unlocked phone, as the lock image shown upon restarting is unlocked, and as indicated in fastboot mode.
I figured it is the radio that is messed up. So I attempted to return to stock on my friend's phone. However, USB cable does not function properly, as I have attempted fastboot multiple times such as "fastboot devices" with the proper drivers installed etc. Using AirDroid to move the files, I've entered recovery mode only for it to load to the red triangle and then it restarts.
Also have repeated the steps after factory resetting. I am out of ideas guys, hoping maybe someone can provide some insight. Greatly appreciate it!!
Galaxy Nexus is the GSM one, not LTE. Thanks again.
-Thiefa

The red triangle is the stock recovery.
Having ADB working does not mean fastboot will work as well, they require different drivers, check in Device Manager for something like Android 1.0 or Android, then update drivers for it. There is a nice guide in this section by Jubakuba.

Will look into the guide.
The thing is, with the phone plugged into any computer, it doesn't show up at all on the device manager, in order for me to update the driver.

I don't use the toolkit in general, but it's probably the easiest way to get the proper drivers installed.

The drivers are a pain the the arse.
Actually, i did that for my N7, install the drivers and the toolkit never saw the light of the day anymore.
Btw regarding the naked drivers, plug the phone in > device manager > update drivers > then direct to the naked drivers folder right?

See the problem is I've updated the drivers and everything.
Whether in Odin, I don't see the phone pop up when I plug it in.
And no IMEI shows when I use a command prompt and attempted fastboot devices.
I'm just going to tell my friend to return it to Bell.
Thanks guys.

[Q] Galaxy Nexus kinda bricked, need help!

Hey guys
Ok so I have a bit of a tricky problem. I got in over my head on my nexus and tried to install ubuntu mobile with a friend. Suffice to say things didn't go so great and now my nexus wont boot, when i turn the phone on it sits on the Google screen. To make matters worse, no computer I plug the phone into can see the device. The strange thing is I can still boot to cwm recovery mode but there is no longer an android image to flash from and I can't load one back on.
Any help you guys can give would be greatly appreciated.
Cheers

Download the factory image from here https://dl.google.com/dl/android/aosp/takju-jdq39-factory-5e273f02.tgz. Unzip the downloaded file and you would see a file "flash all.bat". Open this file and then follow the on-screen instructions.
Done! You have flashed factory image.:good:

Forgive my ignorance, but how to do install those files?

If you uninstall all galaxy nexus drivers in device manager, and Windows doesn't at least tell you it needs drivers when you plug your phone in, then you either have a bad cable or a very messed up phone. In that case you'd have a hard time installing universal naked drivers. There's something called 'OMAP flash' you might want to search for and ask about. All I remember reading is that some people have used it to recover their phones in situations like yours. Never used it myself. Yet. You might want to ask efrant. He knows everything.

[Q] Nexus stuck in boot loop. how get to install drivers?

Hey guys i've been looking through alot of google and can't seem to come up with anything so i turn to you awesome people.
My friend got a Galaxy Nexus GSM and he bought it with a boot loop problem. The phone is rooted and bootloader unlocked. I know because i can go to CWM recovery and also theres the unlock sign on it. However I can't get my computer to recognize it what so ever not even mount the storage. I figure i need to get the drivers to install but i need it to be recognized in device manager to do it through a rootkit. I tried to install the ADB drivers but also got no luck. I then tried to get to ODIN for it to work but ODIN won't recognize it either. Is there any way to install the drivers so i can put on a ROM on this. I think the person he bought it from formatted everything and messed it up. Is there anyway i can install the drivers without getting it to recognize first? I tried it in windows 7 and in windows 8. ANY HELP IS GREATLY APPRECIATED!!!

First off thanks so much for the reply and help it is very aprreciated!
Secondly i did come across this sticky however like i stated the phone is in a boot loop which means i cant get past the google logo in order to set it in developer mode and set usb-debugging neither can my computer recognize the phone when i plug it in, using the original cable i've tried every port there is on my desktop and laptop and nothing comes up in device manager. The phone is completely wiped and no OS is on it. Is there any way i can get a ROM on the phone?! This is one idea i have but i don't know if it'll work, I was thinking of buying a another working nexus install the drivers with that one and then i can get the bootloop one to get recognized? and return the new one. Will that work?

You need to get adb to work with your device, which you can do in a custom recovery. You don't need to have USB debugging enabled, you would if you were booting into the OS, but not the recovery.
You can get drivers setup while in recovery or fastboot just as easy as if you were booted into the OS, so no you don't need another device.

again, read the thread i gave you. if you're still asking this question, read it again.

Isn't that for the nexus 4? And I did pay attention to section A but it told me how to install the drivers which is the same way as every other tutorial I've looked at. My device doesn't show up on my computer and I can't install their way. As for the fastboot driver installation idk what their talking about. I followed the instructions though and got no results. I didn't do the whole thing cause for part C I need the original rom for galaxy nexus and also I don't know if the platform tools zip is for my device so I haven't gone through with it just yet. I'm sorry it's not my phone so I don't want to mess it up even further. I've read about the part with it being in recovery mode with the volume up + power option but I'm at work and haven't tried that yet but I doubt that will work since the phone is clean. Can u please be a little more specific there's 99 pages that I have to go through for that sticky. If u can't it's ok I'll just have to go through it next week. Once again thanks for pointing me in the right direction and giving me some hope.

You reboot the device into bootloader/fastboot mode, then you connect the USB, and there's no sign at all that a USB device has been installed?
Remove all drivers, reboot, and start over. Get a tool for Windows that allows you to really dig on all of the installed drivers and remove all Nexus devices drivers permanently. Rant: Umm, Windows sucks bad. Thanks Linus!

Well, maybe you could try omapflash. If you can't get several PCs to see the device, then something's wrong with the USB port?

I did a little looking up about omapflash and from what i can see so far there needs to be drivers installed first.

To really make sure that the issue isn't on the host side but rather the USB port on the device? Yeah, that would rule it out.
Also, I just remembered: you're not using the USB ports of your PC case are you? Make sure you're using the motherboards' own USB ports.

Windows 8 64-bit...drivers install...stuck
even I am stuck on the same roadblock. have my GNex stuck on the google logo. can access recovery mode though (TWRP 2.5.0.0). Now i just upgraded my PC to Windows 8 64-bit and cant seem to be able to install drivers.
the problem is that almost all the methods require:
1. GNex to be connected with USB Debugging ON
2. install ADB Drivers
3. get into Fastboot or Recovery
4. install Bootloader Drivers
since i cant get past the Google logo on my GNex...i cant perform Steps 1 & 2.
and if i directly try to install the bootloader drivers the OS returns an error (yellow exclamation next to the installed driver)
Added pictures to help explain better.
Thnx in advance.

SOLVED (Dont know how but it worked):

ADB can't find Nexus 7 while in bootloader

Hi everyone,
I am trying to update my (unrooted and unlocked) Nexus 7 2013 wi-fi to Marshmallow via OTA. I have installed adb on my system and download the update package file.
When I connect my Nexus to Windows 10, the system recognizes the device as Android ADB Composite and everything seems to be working as it should. I open a command prompt and type:
Code:
adb devices
and the device along with its id is correctly shown. At this point I reboot to bootloader, so I type
Code:
adb reboot bootloader
the Nexus reboots, enters in the bootloader and the following happens:
adb can't find the device anymore
the device manager puts the Nexus among the Other devices and so it appears no driver has been installed for it.
As suggested on numerous tutorials, I right-click on the device and choose to manually install an appropriate driver. And I expect to find Android ADB Composite in the list and instead the only possible choice is Samsung Android ADB Interface — which does not work, because, naturally, Nexus 7 is not a Samsung device.
I have tried to solve this issue by installing the google usb drivers using the 15 seconds install and it didn't help at all.
What can I do to overcome this issue?

Once you're in the bootloader, adb will no longer be able to see the device. You need to use fastboot to carry out any commands while in the bootloader.

Hi UncleMike,
thank you for your reply. I am a bit confused: (once the Nexus is in recovery mode) how do I initiate sideloading if adb can't find the device?

I'm only familiar with flashing images while at the bootloader. I've never had to side load anything, so I don't really have an answer for you.

I had a similar issue myself when I started using ADB.
What I found happened, is that once you send the tablet into bootloader, you have to go into Device Manager on your windows machine and tell your computer to install the driver for your Nexus. Why it does this, I don't know. I had to do it yet again once I moved the Nexus into recovery mode to flash the OTA update as well. Good luck. Let me know if you need help with what I (poorly) tried to explain above!

Adb only works when in recovery or Android. Fastboot only works when in bootloader.

If you have to go through all that, something is broken with the Android driver setup on your computer. I plug any of my Android devices (N6, N7, Moto X, LG G3, Xperia Z3v, or Moto Xoom) into my laptop and they're automatically recognized.

If I am just accessing my Nexus 7 in Windows, yes, the tablet is normally recognized. However, once you send it into bootloader and recovery, the computer recognizes the tablet, but it knows it is not in its normal setup...I guess. It just needs some prodding to install the driver at each stage. The only reason I knew how to do this is because I followed directions on this online somewhere.

Hey guys I suggest using this tool called universal adb driver it will install all the drivers for the n7, I had problems sideloading marshmallow because of the recovery mode not being recognized by windows however this tool fixed it right up. It installs drivers for I believe the Galaxy nexus? But they work perfectly fine for the n7.
TL;DR: drivers fail in recovery mode this fixes it.
