<div class='page-heading'>Fastboot Install Method (No Root Required):</div>
<hr />
<p class="text"><a href="http://developer.android.com/sdk/index.html">You will need the platform-tools from the Android SDK on your computer.</a> Find the SDK Only section on the page linked and install the SDK and download only the platform-tools to get adb and fastboot binaries.</p>
<p class="text">Windows users will need proper drivers installed on your computer. You can try the <a href="http://www.xda-developers.com/universal-naked-driver-solves-your-adb-driver-problems-on-windows/">Naked ADB drivers</a> or the <a href="http://www.koushikdutta.com/post/universal-adb-driver">Universal ADB drivers</a> if you don't already have a working driver installed</p>
<p class="text">On your device, go into Settings -> About and find the Build Number and tap on it 7 times to enable developer settings. Press back and go into Developer Options and enable USB debugging. From your computer, open a command prompt and type:</p>
<p class="text">adb reboot bootloader</p>
<p class="text">You should now be in fastboot mode. Download the correct image file and copy the file into the same folder as your adb and fastboot binaries. Rename the image to twrp.img and type:</p>
<p class="text">fastboot flash recovery twrp.img<p></p>fastboot reboot</p>
<p class="text">Note many devices will replace your custom recovery automatically during first boot. To prevent this, use <a href="http://www.google.com">Google</a> to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.</p>
