Google’s Pixel download pages offer two routes back to factory software. Choose between them before downloading a file: they have different requirements and different effects on personal data.
OTA or factory image?
| Full OTA package | Factory image |
|---|---|
| Intended for restoring factory firmware, including after a failed OTA update. | Useful when returning from a custom build to factory software. |
| Does not require unlocking the bootloader or wiping the device. | Installation erases the device’s data. |
| Google full OTA downloads | Google factory-image downloads |
Google describes full OTA sideloading as the easier, safer option in many cases. That is a reason to read its OTA instructions first, rather than assuming that a factory image is the normal update method.
Check the device and build
Choose the exact device section on Google’s page. Read any model-specific warning before selecting a build, especially when moving between Android versions. Google publishes separate warnings for some bootloader updates; a general flashing guide cannot replace them.
The release date and Android security patch date are different fields. Use Google’s build information rather than treating the date on a Romzip article as the age of the firmware.
After the download
Save the source address with the file, then compare its checksum with the value on that page. Follow Google’s installation instructions for the selected route. Keep a backup even when using a method that does not require a wipe.
