Title. I don't know what went wrong, I followed the steps but I might have ended up downgrading the sysnand somehow. I don't know, but it ended up as 2.1 at the final steps of downgrading to 2.1. What do I do? I don't want to freak out, and I hope I don't have to. EDIT: I can boot without SD card, but it's 2.1.
