So I was installing things from Cydia to set up my A1A Premium theme, and when I clicked "Confirm" my whole iPod crashed and restarted. So I tried again, installing FiveIRows and FiveColumns, and these would delete Iconoclasm. It crashed and restarted again. Now whenever I click on Cydia, the loading screen pops up (because of my theme) and then it shuts down, but only Cydia. Like my iPods still on, just Cydia closes. I tried changing my theme, and all the same thing happens. Does anyone know how to fix this?
