I have an iPhone 5 with a broken power button. Not the smartest thing to put an iOS beta on, I know, and I fully deserve whatever subsequently happens. Anyway, I noticed it was getting a little wiggy, so I tried to reboot using the Assistive Touch method. No matter how long I held it, it wouldn't give me the "slide to power off" switch. So I set it to "bold text" under Accessibility, which triggers a reboot. Now it's sitting here with a black screen & the little spinning wheel, and shows no inclination to do anything else. I can't put it into Recovery/DFU without the power button. Can anyone suggest an option other than letting the battery run out?
