I have a Raspberry Pi 3 B+, and none of the operating systems that usually work on the RPi 3 will boot. I've done a small bit of research, and I think this has something to do with an outdated bootloader (not quite sure)?
The Ubuntu Wiki has some information here:
Booting the official Pi 2 image on the Pi 3B/3B+
It states that in order to boot on a Pi 3 B+, you need to update the boot files:
For the Pi 3B+ you will also have to update the Pi bootloader files (bootcode.bin, fixup.dat and start.elf) on the system-boot partition.
With instructions on how to do so here.
I followed these instructions and, being the inexperienced person that I am, caused a kernel panic.
Is there a way to modify any Pi 2 image to boot on the Pi 3 B+?
