I followed the instructions.
With lsblk you can check which drive is your eMMC.
With Manjaro it's probably mmcblk2.

sudo dd if=/boot/idbloader.img of=/dev/mmcblk2 seek=64 conv=notrunc,fsync
sudo dd if=/boot/u-boot.itb of=/dev/mmcblk2 seek=16384 conv=notrunc,fsync

Not sure why the second command failed on your PBP.
My heart rate is coming back down to normal. I don't have anything critical on my PBP, but I don't have time to deal with bricking it.



I typed in the commands from the output of sudo pacman -Syu very carefully using mmcblk2.


Code:
A new U-Boot version needs to be flashed our install drive. Please use lsblk to determine your drive, before proceeding.
You can do this by running:
# dd if=/boot/idbloader.img of=/dev/mmcblkX seek=64 conv=notrunc
# dd if=/boot/uboot.img of=/dev/mmcblkX seek=16384 conv=notrunc
# dd if=/boot/trust.img of=/dev/mmcblkX seek=24576 conv=notrunc




I did not include conv=notrunc,fsync, just notrunc, as shown.



Rebooted fine.



I took it on faith to use blk2. I'm not sure how to know that with lsblk's output.


Code:
NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT

mmcblk2      179:0    0  58.2G  0 disk

├─mmcblk2p1  179:1    0 213.6M  0 part /boot

└─mmcblk2p2  179:2    0    58G  0 part /

mmcblk2boot0 179:32  0    4M  1 disk

mmcblk2boot1 179:64  0    4M  1 disk

└─mmcblk1p1  179:97  0  3.7G  0 part
