Hey guys, Long time lurker, first time poster. Though various things I have read here and fiddled around with, I have pretty much made the stuff on my R4 cart completely incomprehensible, and I would love to return to a clean slate, so to speak. I had a look in the FAQ and searched a bit, but I was unable to find what I was looking for. I'd like to completely format my R4 and reinstall the latest Firmware (I'm not sure whether it should be TTmenu or YSmenu, from what I have read going with YSmenu seems to be the superior option). Is there a guide already in place for this kinda thing? And is there a tool I should use to format my microsd completely? I deeply apologise if this has been covered before, but I had a look and I couldn't find anything. Thanks.
