Bootloader Unlock

The bootloader of the Pixel Watch 3 can be unlocked by enabling “OEM unlock” within the Android developer options, rebooting into bootloader mode via ADB and unlocking afterward via fastboot.

# reboot to bootloader
adb reboot bootloader

# check if the watch is unlockable. If yes it returns "1"
fastboot flashing get_unlock_ability

# ask the device to prompt for bootloader unlock
fastboot flashing unlock

After issuing the unlock command, the action must be confirmed on the watch.

Repair

The Pixel Watch 3 has replaceable straps, but the device is glued shut, making repair attempts harder.

Firmware

OTA firmware images are available on developers.google.com. The zip files contain a file called payload.bin that can be extracted with payload-dumper-go.

Once extracted, the partitions are contained in named image files. e.g. boot.img.
