To be far this PiZeroW hadn't been started in a while (too long) so my own fault. [insert your preferred search] to the rescue as usual. This page was the real help; to summarise the steps then
- take out the microSD card and connect to computer
init=/bin/shto the command there (this is in 'boot' that Windows or Linux will find)
- microSD back to Pi, and boot
- Will boot straight to the command line, if it appears to be stuck hit return a few times to confirm the prompt is there.
suto become root user
- I had to make the filesystem writeable with
mount -o remount,rw /dev/mmcblk0p2 /
passwd pito reset the password to
shutdown -pto shutdown
- microSD back to the computer to undo the changes to the
- and then back to the Pi
Though I had to to put the Pi case back together as it is an acrylic layered on that promptly fell completly apart. (Extracting the microSD initially required taking the case apart slightly).
