How to not add an SD card to the Raspberry Pi
A while ago I found out that my Raspberry Pi B+ was not broken after all. I tried it with the SD card of my new RPi 2 and it worked great. So I started searching for some spare SD cards – everyone has a ton of them lying around anyway, right? Hah! Not me apparently. The only card I ended up with had a broken case and therefore didn’t fit into the Raspberry. The SD even had an old image of Raspbian flashed on it already – apparently I used it in the past for some projects.
In my despair I decided to directly solder the SD card to the tray on the RPi. The idea wasn’t even half bad since I didn’t care about the old Pi and just wanted it to work again somehow.
And it did work! I was very careful with the soldering and I even had to bridge one of the pins on the tray in order for it to work. The bootup went fine and I was in high spirits since I kind off felt like I wrecked the Pi in the process of soldering. My excitement lasted exactly 8 more second until Raspbian asked me for the password.
This is where it gets really sad. Not even had I changed the default password on the old Raspbian install, I apparently even set a good one. I spent the next few hours trying different passwords, got an expert in ssh-brute forcing and finally gave up. I had no way to flash a different image on the Pi since it was soldered to the board like the image shows.
What did I learn? Spend 6 more bucks and buy a decent SD card.
