This tutorial might seem complicated if it is your first time ever using the command line, booting into Fastboot Mode, or doing any other tinkering with your smartphone. Once Fastboot.exe tells you that the process has been completed, you will then want to enter the “fastboot reboot” command so that you can reboot your OnePlus One and then setup Android all over again. It’s basically doing a 100% factory reset so remember, you will lose your data when you unlock the bootloader for the first time. The next command you want to enter is “fastboot oem unlock” and this is what will wipe your OnePlus One completely clean. For your OnePlus One, this string of letters and numbers will be different.Īs long as you got a positive result from your fastboot devices command, we can then proceed with the tutorial. In this example, the CB5A1D8J42&ZLP string of letters and numbers is the PC’s way of identifying this specific device. As you can see, after the fastboot devices command was entered, there is a device listed before it goes back to the command prompt. Look at the image above for an example of what it should look like.

If you don’t get a positive response out of this command then you have not installed the USB drivers properly.

This first command included in the tutorial is just a test. Go ahead and boot your OnePlus One into Fastboot Mode and then issue the first Fastboot command. If you aren’t quite sure how to do this, I have written a tutorial on how to boot the OnePlus One into Fastboot Mode. So, once you have ADB and Fastboot installed, go ahead and boot up your OnePlus One into Fastboot Mode. I like using this minimal ADB and Fastboot installation because it puts an entry in your Start Menu so that you can launch the command prompt directly in the ADB and Fastboot directory, allowing you to quickly and easily start issuing commands to your smartphone via these programs. You can follow the guide I wrote on how to install ADB and Fastboot as it is quite an easy process. Once you have the proper USB drivers installed and setup correctly, then you’ll want to have ADB and Fastboot installed onto your computer. If this is the case, you might want to follow this guide and install Samsung’s USB Drivers. If you do not get any response when you type “fastboot devices” while the OnePlus One is in Fastboot Mode, then the USB drivers are not setup properly. A lot of people have reported success by installing Koush’s Universal ADB Drivers so that should be your first attempt.
