How to Root Pixel 4 and Unlock Bootloader



If you have something like a Samsung or a OnePlus device, rooting your phone might not seem very necessary. On a Pixel though, features such as network speed indicator in the status bar are still absent. For power users, stock Android is still pretty barebones, although it is a lot more polished and simpler. Google Pixel 4 and Pixel 4 XL, like other Google Pixel devices, are easier to root. For one, unlocking the bootloader is simpler. Moreover,  Google provides easy access to all firmware images for these devices. And you’ll need that to root Pixel 4, right after you unlock the Pixel 4 bootloader.

Warning

At this point pretty much everyone who is into rooting their devices knows about the risks. Yet, we’re duty-bound to let you know anyway. It also helps that we can say “told you so” in case you manage to horribly mess up your device.

Unlocking the bootloader will void your Pixel 4 warranty. Once rooted, you will also not be able to directly install OTA updates on your phone, at least, not without losing root access. You should also realize that to root your device, you’re depending on a third-party mod, by someone you don’t know. And the mod affects your device on a system level. Needless to say, it is a risky affair even if you trust the mod maker’s integrity. There is always a chance that you might miss something, or things just go south anyway, no matter how careful you were. So proceed at your own risk. Neither DroidViews nor the developer of the root mod can be held responsible for any damage you do to your device.

Also, keep in mind that unlocking the bootloader will completely wipe all data from the device. This includes apps, settings and even the contents of the internal sd card (pictures, music, etc.). Copy all important files off the phone onto a PC or upload them to a cloud.

Download Pixel 4 & Pixel 4 XL firmware

When you flash the Magisk installer zip from TWRP recovery, it patches the current boot image. That’s how it installs itself. Unfortunately, TWRP recovery is not yet available for the Pixel 4. But since we know how Magisk does things, we can do it manually. You will need the stock boot image for your device though. Google lets users download the firmware images from their firmware download page for Pixel devices. Make sure you download the appropriate firmware. For your convenience, we’ve included the latest firmware links for the devices below.
