Good to hear you got it working! It makes a big difference when you no longer care how many apps you have installed because you have so much room now!
I'm not sure why it seems everyone has to try different things to get it working (I'd be curious to know how many were able to just follow the steps straight up and make this work). Seems like you just have to spend time with it to get it going, but I'm glad I stuck with it as well. What's interesting is that I didn't even use sdformatter, but tried other countless ways to do it (including booting puppy Linux to use Linux tools to partition/format the card). My final step happened to be just creating that directory.
