Adding count probably cut the image short, it is not necessary, I generally always us bs=4MiB

Well, I copied the card from the 2GB rpi4 using:
dd if=/dev/sdf of=card.img bs=1M count=9000 status=progress
and wrote another card using the reverse command:
dd if=card.img of=/dev/sdf bs=1M count=9000 status=progress
So, I expected it just to *work* when I put the card into a brand new
4GB rpi4.
Alas, all I get is the steady red LED and a handful of flashes from the
yellow ACT LED. The 2 Ethernet LEDs come on steadily too.
That's why I was asking whether you experts would know about going from
a 2GB to 4GB machine would normally just *work* or not.
Thanks in advance for any insights.
