I got my new Galaxy Nexus today, finally. Of course, the first thing I went to do was unlock the bootloader so I could have a proper (read: rooted) Android device. I ran into a couple of hiccups along the way, however, that didn’t seem to be common for the older Verizon version.
This is the error I was getting once I got to step 10 (which wasn’t step 10 at the time) of this guide. If this looks familiar, and this is where you’re stuck, then you will need to continue from step 8.
This guide assumes that you’re using Windows 7.
Step 1) Download the Sprint Galaxy Nexus 4G LTE drivers (Direct link to the exe on Samsung’s site. Do not download the Verizon version). It’s a normal installer, so double-click and follow instructions as usual.
Step 3) Download the Android SDK (to get ADB). If you’ve never installed the SDK before, follow the directions on CyanogenMod’s wiki.
Step 5) Plug your phone into your computer.
Step 6) Hold Shift and Right click in C:\android-sdk-windows\platform-tools and choose “Open Command Window Here“.
Step 7) In the command window type: adb reboot bootloader. This will restart your phone into the bootloader (see photo to the right). If you get “error more than one device and emulator”, try restarting your phone and doing step 7 again.
Step 8) Your computer will attempt to reinstall drivers for the phone. If it fails, follow these directions.
Step 8a) Go into your device manager. You should see, under “Other Devices”, something like “Android Device 1.0″ – if it doesn’t show up, you might need to reboot your computer.
Step 8b) Right-click on the device and click “Update Driver Software…”
Step 8c) Click “Browse my computer for driver software” and then “Let me pick from a list of device drivers on my computer”
Step 8d) Leave “Show compatible hardware” checked, and “Samsung Android ADB Interface” should show up under “Samsung”. If it shows up multiple times, click the first one (if this doesn’t work you might have to go through and pick the next one down on the list until it figures out which one it wants).
Step 8e) Click next, click “ok” on the warning that says that the driver might not be compatible, and wait for the driver to install. It should tell you the driver was installed correctly. If it was not, you might need to repeat step 8d.
Step 8f) Unplug your phone and reboot your computer. Once you rebooted, plug your phone back in and wait to see if it connects successfully. Your phone should still be in bootloader mode. If not, repeat step 7.
Step 9) Go back into C:\android-sdk-windows\platform-tools and reopen command window (as in Step 6).
Step 10) Type: fastboot oem unlock. The window will say “waiting for device” so be patient. Do not press the start button on your phone.
Step 12) Congratulations! Your bootloader is unlocked. Unplug the USB cable.
Step 14) Use the power button to select Start to reboot your device.
Step 15) If the phone loops during boot, do not remove the battery. You may need to wait for the device to do a factory wipe before it boots.
