[Q] Stuck in Fastboot Mode?

Hi,
I have an O2 retail Galaxy Nexus. Before I began to use the phone I thought I would root it now.
I've read through the instructions and tips but unfortunately my PC can't find the drivers...
I could still access the phone so I opened the .bat for Windows Superboot.
CMD read < Waiting for Device> so I closed the cmd after waiting.
The phone now seems to be stuck on Fastboot Mode. Holding buttons or using the screen do not do anything.
This is my first Android device.
Is there a way for me to get back to normal phone mode until I sort the drivers?
I would be tempted to remove the battery if this were any other circumstance.
Will the older threads about Fastboot being stuck also work?
Thanks in advance.

I hit this myself and yanked out the battery to overcome it. Sorry if that's not what you want to hear, but I do now have a rooted device.
In response to fastboot freezing at <waiting for device> you need to install the fastboot drivers (these are not included in the root zip). Google around to find the best way to install them, I ended up installing pdanet onto my PC - as this has them included - and then removed the application after the drivers were installed.

Thanks for the reassurance, el3ctrik. Battery pull allowed it to boot normally.
Think I'll wait til the morning before trying again... Read some more articles, and try the pdanet method.
Ta!

I remember struggling with the drivers when I rooted my NS - I also ended up installing PDA net to sort out the issue.

I'm looking at buying a GNex for next to nothing, but the seller says it's stuck in fastboot. Came across this thread after a search, is this a fixable issue?

You need to install two drivers. Actually, it is the same driver, it just needs to be installed twice - once when your device is booted normally, and once when it is booted in fastboot mode.
I personally would use the Universal Naked Drivers by 1wayjonny that bk201doesntexist mentioned, NOT the PDA drivers or Samsumg drivers or any other ones. 1wayjonny's drivers do not install any other software on your PC - they are just the drivers, unlike the PDA drivers.

[Solved] Do I need to uninstall/reinstall drivers? If so, how?

Hi everyone,
I'm currently trying to upgrade my phone from Yakjudv to Takju/JB. Unfortunately I've run into some issues, and as they are quite different from the questions in my original thread, I thought it best to start a new one. I do apologise if this was the wrong thing to do! I just thought that an answer to this may be helpful for others, as my searching for an answer is coming up blank.
Before I found XDA forums, I had downloaded and installed Wug's toolkit, and used it to manually install drivers for my phone. This led me to being able to find my phone's serial number when I load toolkits or run adb devices tools.
I then tried to backup my ROM using the method here: http://forum.xda-developers.com/showpost.php?p=21266325&postcount=239
Unfortunately, I got an error saying 'can't mount SD Card' (presumably because the GNex doesn't have an SD Card). Being worried about this, I thought it might be a driver based issue, so I tried to uninstall my drivers by:
1. uninstalling them from device manager (including deleting the driver software);
2. disabling downloads of drivers in windows; and
3. uninstalling all entries related to Galaxy Nexus, Google and Samsung in UDBview
I restarted, plugged my phone in, and the phone suddenly reinstalled, finding drivers on its own. It showed Galaxy Nexus and Samsung ADB device as being installed. When I tried to manually install universal drivers from here:http://forum.xda-developers.com/showpost.php?p=29044502&postcount=735 , I was told by my PC that up to date drivers were already installed.
I don't seem to be able to uninstall the drivers, no matter what I do. I have even tried to uninstall the drivers using Galaxy Nexus Toolkit (I'm trying to avoid using this, but thought it might do the job).
Is this a problem?
If so, is there anything I can do to uninstall the drivers properly?
Thank you so much in advance, everyone!

Google USBDeview, and download the application. When you run the program, make sure to right click and "run as administrator". This will show you all of the drivers installed on your computer. Delete anything that says "Samsung" "Galaxy" or "Nexus". This will give you a clean slate to start with.

Thanks for the advice. I have tried to do this, and uninstalled all of the Google/Samsung/Galaxy/Nexus options, but the minute I plug my phone in, it all just reinstalls!

Thanks for this. I have used it to install the drivers for when in fastboot mode, and I forced installation for the Samsung ADB Device that showed up in my Device Manager.
Do I need to do anything for the driver for the "Galaxy Nexus" device?
Thanks so much!

Cannot stop USB drivers from auto-installing

Hello,
I have searched the forums and Google, and was not able to find anyone else with this issue, so here I am.
I'm on Windows 7 x64 with a stock Canadian Galaxy Nexus 4.0.1 (yakjuux.)
I am trying to install GNex Toolkit and am unable to get past the first step. No matter what I try to do, any time I plug in the phone, it installs the default drivers.
Device installation settings are set to "never install drivers from Win Update." Phone is in development mode, I have removed Google Nexus from my devices (and checked the "delete drivers" box, though it doesn't even appear anymore), there is nothing for Samsung in Programs and Features, I have used USBDeview and there is nothing for Samsung/Nexus. I've tried using PDANet to no avail (I get error 103). I tried using "uninstall drivers" with GNTK, no dice (it seems to just remove a registry entry).
Any other ideas on how to make my PC install the drivers I want and not the default ones?
Thanks.

I have read that entire post and Bourne-nolonger's guide. Instead of showing up as "Android 1.0" device in Device Manager, my phone always shows up as Galaxy Nexus, with no yellow triangles or any other issues. (Yes, developer mode is enabled, and it seems to make no difference to how my computer responds.)
From Bourne-nolonger's guide:
"As soon as you enable this Windows will pick up a new device and it will attempt to install a driver - this will fail (or hopefully it will)." - mine never fails, it always installs drivers from somewhere. When I attempt to install new drivers to the Google Nexus device using UNK 0.7, Windows tells me that I already have the newest drivers.
Should I be restarting my PC after every install/uninstall of drivers? That's the only thing I can think of....

Absolutely.

Here is the sequence I followed:
- phone plugged in
- USB debug mode on
- uninstall phone from Device Manager
- USB debug mode off
- uninstall phone from Device Manager
- reboot
- reconnect phone, it installs with no problems
- enable USB debug mode while plugged in
- phone installs again, exactly like the previous time, with Galaxy Nexus in Portable Devices
So it appears my computer doesn't care if it is in USB debug mode or not. It sees them as two separate devices/states of device, but installs the same drivers for both.
edit: tried doing the same in fastboot mode; the Device Manager recognized it as Fastboot mode, but did not let me install the proper drivers, saying that I already have the newest ones.

This is what I would do:
1) Unplug your device from your PC.
2) Go into Device Manager and in the View menu at the top, select show hidden devices.
3) Uninstall every driver related to the GNex/Samsung/Android/etc.
4) Reboot your PC.
5) Make sure your Device Installation settings are set to never download drivers from Windows Update (as per bourne-nolonger's post).
6) Make sure USB Debugging is enabled in your GNex's settings.
7) Plug your GNex into your PC.
8) In device manager you should see Android 1.0 with a yellow "!". Right-click on that and update the driver from where you downloaded 1wayjonny's driver.
9) Reboot your device in fastboot mode.
10) In device manager you should see Android 1.0 with a yellow "!". Right-click on that and update the driver from where you downloaded 1wayjonny's driver.

Done, with no luck: instead of Android 1.0, I get a normal GNex install; with fastboot I did get it to show Android 1.0, and installed Samsung Galaxy Nexus Fastboot Interface using the downloaded drivers.
When I am uninstalling GNex from Device Manager, it never asks me to delete the driver as well; it asked me once and I can't get it to do that again. With fastboot, it did ask me, and that seems to be the only difference in the process.

At least you got the fastboot driver installed properly.
I'm out of ideas for the ADB driver though.

Seems to be a problem with my PC, so I will try it with a different machine. Thanks for your help!

Ignore this. Wrong thread.

Help GNex has no OS and won't connect to a PC!

Windows 8.1; but had same problem with Windows 7 computer.
USB device not recognized
The last USB device you connected to this computer malfunctioned. And Windows does not recognize it.
Windows has stopped this device because it has reported
problems. (Code 43) A request for the USB device descriptor failed
Tried using WUGS Toolkit to install drivers, not happening.
The phone charges via usb port with no problems
On top of that, daughter wiped phone, there are no ROMS, or usable backups.
I can get into TWRP Recovery, but it can recover what isn't there. Tried factory
reset, still nothing. No matter what I do, I get No OS Installed! Are you
sure you wish to reboot? If I do reboot, just get GOOGLE screen with lock
symbol.
Without being able to get a computer to see the phone, I can't get a ROM to
load.
Maybe change USB port with cable? But I don't want to do that if the problem
is software related.
Any ideas what I can do???

I just went through something similar like this last week, what a pain in the A$$.
Not entirely sure if this will fix your issue, but hopefully it'll help some how.
I ended up having to manually install galaxy nexus driver so I could sideload a ROM since I formatted my internal storage to test out this new F2FS BS... Anyways.
LOL
First you'll need to download and unzip "universal naked driver 0.72" Google it.
Now, without your GN connected open device manager and THEN when you plug in your GN to your PC you should see it pop up in the portable devices section.
AND also under other devices there should be "galaxy nexus" right click on it and click "update driver software"
Click "browse my computer for driver software" select the unzipped universal naked driver folder, click next and click "install this driver software anyway"
Now it should show "Google galaxy nexus ADB interface" in device manager under Samsung Android Phone.
Reboot GN into bootloader
OR
recovery (if you have a ADB supported recovery eg. TWRP 2.7.0.0, and enter ADB mode)
Now there are 2 ways to do flash an Android OS, some may find 1 easier then the other:
download/install "Wug's Nexus Root Toolkit aka NRT v1.8.3.sfx"
Google it.
Run NRT and it'll instruct and guide you through the steps required and whatever is needed to continue, eg. Select device, download TWRP 2.7.0.0...ETC.
Or
Download/install ADB setup 1.3
Google it.
I found this method a little more simpler.
Open the folder you have your ROM/gapps zip files saved on your PC, hold down shift key and right click on the folder, click "Open command window here"
Now in the command window type in "adb sideload XXXXX.zip"
XXXXX = COPY/PASTE the ROM file name. Eg. 20140615PA443RC2.zip
Press enter and now it'll flash the ROM onto your GN.
Repeat the same steps for gapps/kernel zip files.
Reboot your GN and enjoy.
BTW
I'm still loving running ParanoidAndroid Jellybean 4.1.2.

Its like pain in the A** to install phone/adb drivers in win8/8.1
I had a similar issue with my gNex a while ago but i had the drivers installed in my pc so it wasn't that difficult.
Why don't you try to install this toolkit http://forum.xda-developers.com/gal.../gnex-toolkit-v11-1-0-drivers-backup-t1392310
When you run the toolkit, it may ask you to select your device, build number etc and also about installing device drivers.
Install the drivers through it and then connect the device in recovery (twrp) mode.
it should detect it and then you can push files/roms to sdcard (internalMemory) using adb push or the built in options in the toolkit.
then flash the rom and you're done
and i recommend using win7 or xp or vista for doing this because the driver installation in win8/8.1 is a bit difficult compared with other previous windows versions but there is still a way to install drivers in win8/8.1 its just a lengthy process
All the best :good:

OK, downloaded universal naked driver 0.72, connected gnex, but it only shows up under Universal Serial Bus controllers as Unknown USB Device (Device Descriptor Request Failed), not under Portable Devices, and will not allow install of of universal naked drivers, & yes I have toggled to allow win 8.1 to installed unsigned drivers. Since I cannot get phone to turn on to full android, it is not recognized. Any other suggestions?

You have to go to the device manager, double click on the "unknown usb..."
a dialog box may appear and then click on the 'driver' tab.
There u may find update/install driver button.
click on it and another window may open.
then select browse my computer for driver software and go to the respective folder where the drivers are.
then click next and it may install the drivers.
if you have installed the toolkit then you may find a folder in the toolkit's installation folder which has drivers in it.go through it if you want :good:

Cannot install USB drivers for Razer phone on Win10

Howdy,
I'm trying to get my phone unlocked and rooted. As the first step, of course, I'm trying to get the Google USB drivers to install, but I simply can't. I feel like I'm the only person having this issue, though because I cannot find a solution... The steps I'm following:
Downloaded the latest driver zip from Google
Open Device Manager
Expand Portable Devices
Right-click on the Phone entry (notice, that's the entry, "Phone". Not Razer.)
Choose Update Drivers
Browse my way to the drivers folder and click Next.
Windows then returns immediately "The best drivers for your device are already installed", and shows that it's an MTP USB Device.
I noticed that under USB devices, there's an ADB Interface device listed, and I get the same results when I try to update that, too (excepting it says it's an "ADB Interface" device, of course). I have tried uninstalling both devices to get the drivers to install, but no such. I've rebooted both phone and computer as well.
On the phone, USB Debugging is turned on, and USB mode is set to MTP file transfer.
Please help!

Figured it out...

In case anyone else is seeing the same issues, I wanted to put my resolution up: I'd been trying to install the drivers with the Razer booted. On a whim, I rebooted it into Download Mode using "adb reboot bootloader". Once there, I had an Android Device listed in Device Manager. I ran the driver update wizard, and installed the "USB ADB Interface" option from the choices presented. I was then able to run the OEM unlock command and received the confirmation prompt on the Razer. Yay!
Now, since it's been so long, I've got to re-back-up everything so I can actually do this thing. LOL
