I hope you know to get DECENT SD cards, this is quite important
Better sandisk or any samsung evo are best, larger tend to be faster (>32)
Larger will have more room for wear leveling, not so important for a seldom booted
mbr or gpt mbr is 1 or 34 sectors at start of card
bios equivalent, idbloader, uboot, ATF (arm trusted firmware) are in 1st 16M
idb starts 64 sectors, uboot 8MB, atf 12MB, user partitions at 16MB (32768 sectors)
often uboot and atf are joined together, uboot padded so atf at right location
If this is happening, uboot will be >4MB,, maybe 6.5MB
Specifics: you didn't say if you tried mrfixit's distro, I recommend for a repair/recovery
(on smaller SD card, 16M, so you have enough room to copy another image too)
Do the update, icon on bottom bar to right, then you have his uboot, updated if you wish to use it
(/usr/bin/mrfixit_update.sh,, updates uboot & kernel)
Manjaro has 2 images, one for ONLY use on SD, other to install to emmc FROM SD
(ie , burn to SD, use to install to emmc, NOT a live system, press esc after 30s to show screen)
PCM's uboot can be found from git addressed in forum thread General Discussion ->
U-Boot with direct NVMe boot support for eMMC/SPI Flash
My guess is that you don't realize how important GOOD quality SD's are
This is not a camera, in a cell phone the os is not on card
If you check the cards that boot, I bet they say U1 or U3 as well as class 10
--edit-- BTW, always check for fakes, 1st thing when you get card,
even amazon has sold fakes,, f3 or htestw
