This question already has an answer here:
I am stuck at work, and i tried to install ios 8.4 to my iPhone 5s, now it's stuck on the "Connect to iTunes" screen, well I don't have a computer with iTunes on it. My laptop is my work computer and it's and ASUS, and I can't install iTunes on any of the desktops here because it's not allowed. I desperately need my phone for work right now. I've tried resetting it, locking it, everything.
