New Method – Installing ADB and Fastboot Drivers for Galaxy Nexus on Windows 7 & Windows 8

If you own a Samsung Galaxy Nexus and wish to intensely configure your device by rooting and installing custom ROM, then here is an amazing tool specifically for Galaxy Nexus smartphone that you must check out! Galaxy Nexus Root Toolkit (by WugFresh) is a free, powerful and feature packed program that makes everything easier than ever. The program works for both Verizon (CDMA) and GSM models. Functionalities include: Unlocking, rooting, relocking, unrooting, Flash/Boot img files, Backup and Restore Apps, Flash Stock firmware, and many other options. It has a nice GUI which is great for novice users as they can perform several tasks easily without going through the uneasy command-line process. Moreover, it doesn’t requires Android SDK to be installed.

Galaxy Nexus Root Toolkit includes the relevant USB drivers within the package and has automated driver installation with devcon and pnputil. But you still need to configure the drivers manually which is the most crucial and bit of difficult task in the entire process. Though the program indicates step-by-step instructions to install the drivers but we’re sharing this tutorial to make it more convenient for you. Follow the steps carefully.

STEP 1 – Install Samsung USB Drivers using Galaxy Nexus Root Toolkit

Open Galaxy Nexus Root Toolkit (Run as Administrator), select device model type (CDMA or GSM), and click on ‘Drivers’ option (Device should be unplugged). The driver installation process will start instantly and will be completed automatically. Note: Be patient and let the process finish on its own.

STEP 2 – Driver configuration, a two step manual process:

• Your device has to be configured once when its ON and again when its in BOOTLOADER
• You have to manually configure these drivers through device manager.

Part 1: Configuring your adb drivers

1. Turn your device completely on, enable USB debugging, and connect your device via USB. To enable USB debugging: on your phone, open settings > developer options > check USB debugging.

2. Open device manager: Start > type devmgmt.msc

3. Look for anything that resembles your device: it could say Galaxy, Android device..

• If you can’t figure out which one is your device: Unplug your phone and then replug it while watching device manager.

4. Uninstall this device! Right click the device > Uninstall

5. Now refresh your devices by hitting the “Scan for hardware changes” button.

6. You will now see a new device with a yellow exclamation mark next to it.

7. Now you’ve to install the correct drivers for it.

• Right click the device and choose “Update Driver Software…”
• Now select “Browse my computer for driver software”
• Now in the “Search for driver software in this location:” enter:

C:\Wugs_GnexRootToolkit\data\drivers

• Now Hit enter, agree to the security warning and wait for the driver to configure.
• It could take a few minutes… then tada!

Alternatively, you can do this (this method only works on some computers).

• “Let me pick from a list of device drivers on my computer”
• Browse for “Samsung Devices” and select Next
• Then choose “SAMSUNG Mobile ADB Device”
• Then select next, wait for it to configure, and tada!

Now Test to make sure the adb drivers are working correctly – Firstly, connect your device via USB and confirm that ‘USB debugging’ is enabled. Then open Galaxy Nexus Root Toolkit (Run as Administrator), select ‘adb-phone on’ option in Quick tools and click on ‘List devices’. A command prompt window will appear stating the list of devices attached. If you see an adb device listed as shown below then you’re half done.

Part 2: Configuring your Fastboot drivers

1. Boot your phone into bootloader mode. This can be done directly from within the toolkit, select ‘adb–phone on’ and click on ‘Reboot Bootloader’ option.

OR

When your phone is in completely powered off state, turn it back on by: “Holding both up and down volumes buttons and the power button”.

2. Go to Device Manager. You will now see a device listed as Android 1.0 with a yellow exclamation mark next to it.

3. Install the correct drivers for it.

• Right click the device and choose “Update Driver Software…”
• Now select “Browse my computer for driver software”
• Now in the “Search for driver software in this location:” enter:

C:\Wugs_GnexRootToolkit\data\drivers

• Now Hit enter, agree to the security warning and wait for the driver to configure.

4. You should now see a new device listed in device manager as ‘Samsung Android Phone’ with sub-category as ‘Android ADB Interface’.

5. Now test it – Select ‘fastboot–bootloader’ under Quick tools and click on the ‘Reboot Bootloader’ option. If the device boots into Fastboot mode, then you’re done.

Your drive configuration is complete. This is quite lengthy but is a one time task. Once drivers are setup properly, you can manage your device entirely with this toolkit. 🙂
