I HAVE NO ACCESS TO A COMPUTER. I need to unjailbreak my iPad, but if I click erase all content and settings, it will be stuck on the little white spinny thing (I don't know what else to call it). If their is a website or app, that would be fantastic. Any help would be much appreciated. Thank you in advance.
Added (1). I have also deleted cydia, although it did not help.
