Jailbreak 9.2 5s with iCloud sign in stuck

I am looking to jailbreak an iPhone 5S on 9.2 so I can sing out of an iCloud account that has the password stuck and the email address is no longer valid, but all of the jailbreak tutorials I could find requires me to sing out of iCloud BEFORE the jailbreak (which I can’t do) , and the computer-less jailbreaks seem to be not working as of now, is there a way still to jailbreak the device in this situation
