=== 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.
<syntaxhighlight lang="bash">
# 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
</syntaxhighlight>After issuing the unlock command, the action must be confirmed on the watch.

=== Fastboot ===
You can reach Fastboot Mode without pairing the device by tapping the upper left and lower right of the display right after booting (the first Google Logo). See also [https://support.google.com/googlepixelwatch/answer/13575675?hl=en-GB here].

=== 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 [https://developers.google.com/android/ota-watch?hl=de#seluna developers.google.com]. The zip files contain a file called payload.bin that can be extracted with [https://github.com/ssut/payload-dumper-go payload-dumper-go].

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