I don't know why you think to disregard my advice to back up (emmc) mbr
Your mbr 's partition table is wrong
boot1, boot0, rpmb are sections on the emmc, made by the disk controller
Check the size,, 4M x2 and 12M(??)
Not used for rk3399 cpus
With manjaro, p1 starts at 62500 if that helps
-----
for that matter, if you backed up the 1st 16M of emmc, run fdisk on that file,
then open another tab in xterm (konsole) and fdisk on emmc
edit a partition table by deleting and then re-creating partition with RIGHT sector numbers (from 1st-16M)
if you run fdisk on shared.disk-image.img you will see 64 24639 24576 12M ff BBT
(and this is wrong, OK for a tow-boot install, but NOT to boot emmc, delete this partition)
This represents start of idbloader to end of u-boot.itb
the uboot loader package needs NO partition, it is a RAW read (from cpu specified and fixed locations)
