How to Unlock the Nexus 5 Bootloader



Whenever we get the new Nexus 5, we immediately want to unlock the bootloader. Why? Because if we want to root Nexus 5, put on a custom recovery and flash a ROM, it would be the first step. But you should be warned that unlocking the bootloader of your phone “may” void its warranty, at least according to the unlock screen. You can always re-lock it if you’d like or should you run into warranty claims.

Ready?Here we go.

Steps to follow

*Warning – Unlocking the bootloader of your phone, “may” void your warranty.

*First things first, you need to setup the Android SDK so that you can use adb and fastboot commands. There are countless tutorials around for getting this setup, but it’s really not that difficult any longer to get this up and running. Simply download the latest Android SDK from Google, unzip the contents of the file, and head into the platform-tools folder where adb and fastboot should be located. Open a command prompt from within there.

1.  Enable “Developer options” by tapping 5 or 6 times on the Build number in Settings>About phone.
2.  Hit back once and choose Developer options; check the box for USB debugging.
3.  Plug your phone into your computer.


4.  You’ll need to give it USB debugging access (don’t forget to check the box).
5.  Once you have given your computer debugging access, it’s time for commands. Type in a command prompt:

adb reboot bootloader

(Note:  If using a Mac, it’s ./adb reboot bootloader or ./fastboot -insert comand-)


6.  Wait for your bootloader screen to appear. Once it does (big Android with START), type:

fastboot oem unlock

7.  A bootloader unlock confirmation page will appear. Tap Volume Up to highlight “Yes,” and Power to select it.


8.  Your phone will then be erased and the bootloader unlocked. Shouldn’t take more than a minute or two.


9.  Your bootloader is now unlocked and ready for root, ROMs, recovery, etc.

*Note – We did not just root your phone or flash a recovery or really do much. Your bootloader is just now unlocked and ready for you to tinker as you please. You “may” have voided your warranty though.

10.  You should be on the bootloader screen showing “Start.” Press Power to reboot your phone.
11.  During reboot, your phone will go through a factory reset.
12.  Once it boots back up, you are done. If everything went correctly, you should see an unlock icon during boot.
