Some months back, I posted a guide to backing up a Raspberry Pi SD card using a Mac. I tested it at the time and it worked. It’ll be good to share this, I thought. So I did.
And a good job too, because this past weekend I needed to cook to my own recipe. A long overdue Pi
sudo apt-get upgrade followed by tweaking
raspi-config zapped my system software.
Rebooting the Pi produced nothing but a single flash of the green Activity LED and the reassuring glow of the red Power LED — the hardware probably wasn’t up the spout. Googling confirmed my fear: the software was fritzed.
So I called up my blog entry, just as a reader might, and followed the walkthrough. It took a while for the compressed 16GB image to copy, but I got a working OS. This, second attempt at updating went smoothly.
Hopefully, you won’t need the recovery guide, but if you do, I can confirm it’ll get you out of hot water. Just make sure you have back-up before that happens.
