xu4-not-booting-with-new-kernel

Hello, I just ran a apt-update Sunday on a project and afterwards the XU only have Black screen with blinking _ in the corner, not connecting to LAN, no ssh, etc; red led is on, blue led blinking, no new logs in /var/log.

Google' the issue, and several posts points to the /boot dir - however comparing with a know good SD card, I can't see much difference in this directory - other forum post points that a /dev mount point should be changed (but not to what) 

I can mount the broken SD card and have the following info;

/etc/armbian.txt

Title:            Armbian 5.73 Odroidxu4 Ubuntu bionic next
Kernel:            Linux 4.14.94
Build date:        28.01.2019

/etc/armbian-release

VERSION=5.73

I does seems to be very like below mention issue - however no applicable fix was provided - any assistance in how to unbrick the XU would be most appreciated (beside the obvious start over )
