Hey Jeremy,
My name is Carlos, It was great speaking to you on the phone today. As promised, I've included the steps below. Since each step is very important to the next step, please carefully read and complete each step one at a time.
Download the ‘SDK Tools Only’ zip for Windows (the zip can be unpacked to a specific folder, so don’t download the exe): [url]https://developer.android.com/sdk/index.html?hl=i#Other[/url].
Download the correct factory image and version for your Nexus: [url]https://developers.google.com/android/nexus/images[/url].
Download and install 7-zip so you can unzip the Nexus image for your device: [url=http://www.7-zip.org/download.html]Download[/url].
Make sure you have Java installed: [url]https://java.com/en/download/[/url].
Unzip the Android SDK tools file, then move the folder android-sdk-windows to C:\.
From the C:\android-sdk-windows\Tools folder, open android.bat (may just show android with a file type of batch). It may take some time, but it will load the Android Package Installer.
In the Android Package Installer interface, uncheck everything except:
Android SDK Platform-tools
Extras > Google USB Driver
Press the "Install" button in the Android Package Installer, then accept the license agreements and complete the download and installation.
Unpack these specific files from the Nexus image zip file to the platform-tools folder in C:\android-sdk-windows. Note: There are multiple tgz, tar, and zip files to unzip before you locate all of these necessary image files. Don’t worry if you don’t see the .img extension, it’s still there:
boot.img
bootloader (version info).img ← Note: this file name will be different depending on your device. Please make note of the exact file name.
cache.img
recovery.img
system.img
userdata.img
radio (version info).img - Note: some devices do not need a radio (Wi-Fi only devices). If you have it, please make note of the exact file name.
Press the Windows key + r, then type and run CMD in the box that appears.
Type cd C:\android-sdk-windows\platform-tools in the CMD box, then press enter.
Restart the device into the bootloader:
Power the tablet down completely.
Hold the volume down button while pressing the power button.
Connect the device to your computer.
In the CMD window, type fastboot devices to make sure your device is detected. If it isn’t detected:
Try a different USB cable.
Switch to a different USB port on the computer.
Remove/re-install drivers ([url=http://developer.android.com/tools/extras/oem-usb.html]OEM USB Drivers | Android Developers[/url]).
Try a different computer.
To unlock the bootloader so you can reinstall Android:
In the CMD window, type fastboot oem unlock
Use the volume button on the device to highlight Yes, then the power button to confirm your choice. Don’t worry if the device doesn’t respond right away - it can take a few minutes to initiate and complete the unlock process.
Once the bootloader is unlocked (Lock State - unlocked on the device bootloader screen), type the following commands to reinstall Android (please wait after each command until it shows Finished):
fastboot flash bootloader “bootloader [version info].img” ← Note: you can press your keyboard’s tab key twice after typing “bootloader, and Windows will auto-fill the rest file name for you.
fastboot reboot-bootloader
fastboot flash radio “radio [version info].img” ← Note: Step C is not necessary for Wi-Fi only devices. You can press the tab key after typing “radio, and Windows will auto-fill the rest of the file name for you.
fastboot flash system “system.img”
fastboot flash userdata “userdata.img”
fastboot flash boot “boot.img”
fastboot flash recovery “recovery.img”
fastboot format cache
fastboot reboot
Allow the device to finish the first time startup (which can take up to 20 minutes).
If you have any questions please feel free to reply back to this email.
Thanks,
Carlos
