Until recently, the image for the Asus Chromebook Flip C100P worked at my Asus C201P. With the last updates (I tried reinstalling from an old downloaded system image an as soon as I updated, the same happens) it hangs during the boot:
(I don't know how to add an image here)
The screen contains the message "failed to start network time synchronization" and the last message is "brcmfmac: brcmf_c_preinit_dcdms: Firmware version = w10: Oct 24 2017 02:04:25 version 7.35.349.28 (r674459 CY) FWID 01-aa74a501"
