Google’s Pixel lineup is focused on providing the best Android experience on the market. Further, it is also set up perfectly to act as a test bench for developers that are creating new apps on Android. To support the cause even more and allow enthusiasts greater control over the device, Google also officially allows users to unlock bootloaders of their phones. For a complete step-by-step procedure on unlocking Pixel 4 bootloader, we have the tutorial right ahead.
Once you unlock the bootloader, you would be able to flash system files directly onto your phone and modify existing system files. For obvious security reasons, Google ships all phones with a locked bootloader but allows easy unlock if required. Before we take you through the procedure, make sure you have created a complete backup of your user data as this process will initiate a factory reset and your data will be wiped clean. Again, the process ahead is officially supported and would not require any third-party tools.

Done with the USB drivers? Perfect. The tutorial is on the next page, but first, please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps.
Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. Read: How to Backup Android Apps, Text Messages, WhatsApp, Call History.
If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up. [Tutorial: How to Backup Android Phone using TWRP]
A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow, Nougat and Oreo.
2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
3. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.
If you are a developer and would want to unlock the bootloader, we recommend doing that before you set up the Google Play Store, install apps or anything because the security feature in Android clears out everything from your phone when unlocking bootloader of the phone.
