I have an ipad 3 on 6.1 jailbroken. It keeps crashing. Now I know I can't restore it to 6.1.2, I'd have to upgrade to 6.1.3 and lose jailbreak, which I don't want to do. But what happens if I click erase all content and settings. Will I lose my jailbreak? Will I end up in a boot loop? Will it be fine? Thanks for any advice.
