Why unlock bootloader on Google Pixel?

Pixel phones are Google’s perception of a perfect Android phone. Since Google manages both hardware and software when it comes to Pixel devices, it has become a popular device for enthusiasts and developers.

Now, to fully use the Google Pixel phones and utilize it as a test-bench, bootloader unlock becomes quite necessary. Without it, flashing firmware — be it official or custom — is not possible. Further, if you are looking to test out third-party mods, again, OEM bootloader unlock is necessary.

If the sole purpose for you to unlocking the bootloader is to install or flash a factory image file, we recommend using the Android Flash Tool from your web browser.

How does unlocking the bootloader effect warranty?

In many warranty policies, a bootloader unlock simply renders a warranty useless and void. However, there is a process through which you can re-lock it and return the phone to its original state. This will in turn then return the warranty.

If you have a phone that is over its warranty time limit, unlocking bootloader wouldn’t effect anything. In fact, treat it as an opportunity to modify your phone’s software.

Most OEMs do not support you unlocking the bootloader of your phone. This is mainly due to security concerns and because users might damage their hardware in certain ways which cannot be covered under official warranty. However, Google Pixel fully supports unlocking the bootloader and you doing so will not void the warranty in any way.

Can an unlocked bootloader be locked again?

Before modifying and unlocking, many users are curious about the reversibility of said mod. Well, in case of bootloader lock, you can easily relock it even after it is unlocked. This can be done by reversing the command from unlock to lock.

Reversing will basically return the phone’s software to its official state. For people looking to sell their Pixel / Nexus phone, locking the bootloader before selling it will be an advisable thing to do as it is more secure for the next person. Further, there is no limit to unlock or relocks.
