Warning: Don't Use the rpi-update Instructions

I enjoyed the book, but I did brick my Pi following the rpi-update instructions. (Reflashing the SD card fixed me up.) I’m not the only person with this issue. https://github.com/Hexxeh/rpi-update/issues/22

Thank you for pointing this out. I have used rpi-update countless times on both squeeze and wheezy and I never had any problems. Obviously, a few people haven’t been as lucky as me. I hope that the issue gets resolved soon and I’ll have a look at it myself.

I looked into it a little today and added my findings to the issue. In short, I think it’s safe, as long as you sudo apt-get upgrade first.

Actually, I don’t think it’s the upgrade that saved me. I was trying to debug the script, so I ran it several times before rebooting and accidentally followed these steps:http://blog.pixelami.com/2012/06/raspberry-pi-f…

Thank you very much for sharing this!
