Summary

Fresh install on marlin makes device reboot 2 times last of which into bootloader mode. OS does not boot.

Steps to reproduce

1. start with marlin fully restored and working. this is done by flashing factory image from https://developers.google.com/android/images#marlin. at this stage phone boots from both A and B slots. slots are switched by booting twrp (fastboot boot twrp-3.3.0-0-marlin.img

2. boot into bootloader

3. fastboot boot twrp-3.3.0-0-marlin.img

4. wipe data, system, dalvik. NB! there is no cache only dalvik
