It looks like developer interest is pretty strong with the Nexus 6P and Nexus 5X. There is already a Multi Tool Toolkit to make normal mods super easy. With the Multi Tool you are able to Unlock your booloader, relock your bootloader, flash a recovery, backup and restore your device. There is also an included reboot menu, a logging menu which can be used to log errors on your device and assist developers, and more features are soon to come! Grab the toolkit from the link below.
