I flashed to 1.77, and now my cart just gives me this weird "please discribe" screen, and then the screen "melts". Then nothing. I have tried flashing back to whatever the earliest one is available on the page, 1.75 or something. Tried formatting my SD. Nothing. Just shows that stupid message and melting screen. Any ideas? I have no idea what my firmware or whatever was before I tried updating to 1.77, but it worked fine, and I wish I'd just left it.
