@tera Thank you so much. :clapping_hands: That worked fine. I'm currently updating to Kernel Channel. I didn't have to use DD or BMAP. In regards to BMAP, I'm thinking the partitions aren't at optimum as I used the standard Linux Mint Disk Image Writer utility, I'll enclose a picture below. It appears everything is working fine though and I have full use of the phone's SD card slot with UBTouch running on eMMC.

Looking forward to future development of UBT and wondering if my Librem 5 is EVER going to ship.

So I would call this issue pretty much solved.
