    Shut down the RPi 3B, pull out the SD Card, put it into the RPi 2 and power it on. Please tell me if it runs.

That's what I was trying putting a card initialized and working fine on an RPi 3 into an RPi 2 and it would not boot. Same card booted fine in an RPi 3. RPi 2 boots fine from cards set up on an RPi 2.

It looks as if cards initialized on an RPi 3 will not work on an RPi 2.

Regards

    That is not true. Does your RPi2 boot from a fresh copy of plain Raspbian. How does the RPi3 SDCard fail? Have you been mucking about running sudo rpi-update? Does the card have the ARM6, ARM7 & ARM8 kernels? Are the /lib/modules/* intact?
