Installation

SafeStrap + ddroid from eMMC or SD card

PostmarketOS has some information how to install safestrap: in wiki

(This is the boot method currently being used but we'll probably replace this with droid4-kexecboot to aid kernel updates via deb package)

Flashing the zip file is quite confusing / tricky:

Boot options, select slot with Leste, Activate.

In main menu: Install, scroll down to select ddroid-....zip file, swipe to confirm flash. You will get error, including "ApplyParsePerms, set_metadata_recursive, Error executing updater binary, Unable to mount." Red "failed" will appear. These are normal. Proceed by selecting "Reboot System", you'll get one more warning that system is not installed, swipe to confirm reboot.

Red motorola logo will appear, press search button to continue boot, phone vibrates, then vibrates again, then green led comes on. After about a minute, console appears, then disappears and X comes to life.
