Some of manjaro's uboots are not so good
On a SD, where it is easy, backup good uboots before changing
bs=1M count=16 of=suitable_name,,, since it is same device, no need to mess with mbr
It is not sure if or maybe not some uboot remnant on emmc, this may or may not interfere
(from failed installs)
Because there is a battery, it can remember a "bad state", you may have to do "long presses"
Easiest to reburn image on SD, as your dd command line
If it then boots, then try to install
The long press dance........
If not, hard pwr-off(8s), try start (don't just tap, hold 1-2s, try twice (or 3) times)
If not, hard reset (20+s), try start
if not, try hard pwr-off again
I actually have had to this above dance, somewhat annoying
