This page contains binary image files that allow you to restore your Nexus or Pixel device's original factory firmware. You will find these files useful if you have flashed custom builds on your device, and wish to return your device to its factory state.
Note that it's typically easier and safer to sideload the full OTA image instead.
If you do use a factory image, please make sure that you re-lock your bootloader when the process is complete.
These files are for use only on your personal Nexus or Pixel devices and may not be disassembled, decompiled, reverse engineered, modified or redistributed by you or used in any way except as specifically set forth in the license terms that came with your device.
Updating Pixel 6, Pixel 6 Pro, and Pixel 6a devices to Android 13 for the first time
After taking an Android 13 update and successfully booting the device post update, an Android 12 build resides in the inactive slot (seamless updates for more information on slots) of the device. The inactive slot contains an older bootloader whose anti-rollback version has not been incremented. If the active slot is then flashed with a build that fails to boot, the fallback mechanism of seamless updates kicks in and the device tries to boot from the inactive slot. Since the inactive slot contains the older bootloader, the device enters an unbootable state.
To avoid hitting this state, if you are flashing a Pixel 6, Pixel 6a, or Pixel 6 Pro device with an Android 13 build for the first time, please flash the bootloader partition to the inactive slot after successfully updating and booting into Android 13 at least once. This can be done by following these steps:
Option 1 (recommended): After a successful boot into Android 13 for the first time, sideload the full OTA image corresponding to that build and reboot the device to ensure that both slots have a bootable image.
Option 2 (using factory images): If you flashed your device with the factory image after unlocking the bootloader, after a successful boot into Android 13 for the first time
Extract the contents of the factory ROM
.zipfile, identify the bootloader image in the extracted files, and follow the sequence of events as listed below to flash the bootloader to both the slots. Substitute the name of the bootloader image with that of your device for the Pixel 6 and Pixel 6a.
Start the device in
fastbootmode with one of the following methods:
Using the adb tool: With the device powered on, execute:
adb reboot bootloader
Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device.
Flash the Android 13 bootloader to the inactive slot. The following command is specific to a particular build of a Pixel 6 Pro device. Substitute the name of the bootloader image determined in the first step above, if different, for the image file name argument.
fastboot --slot=other flash bootloader bootloader-raven-slider-1.2-8739948.img
If the flash was successful this command will print
OKAY [ ... ]. Do not proceed unless this command completes successfully.
After flashing the inactive slot bootloader to an Android 13 bootloader, reboot to that slot to ensure that the bootloader will be marked as bootable. Important: Please run the exact sequence of commands as listed below. Don't forget to enter the full line
fastboot reboot bootloaderwhen rebooting. Failure to do so may leave your device in an unbootable state.
fastboot set_active other fastboot reboot bootloader fastboot set_active other fastboot reboot bootloader
Reboot into the current OS. Either press the power button to boot or use the following fastboot command:
