My Sprint Galaxy S4 is currently on Android 4.2.2 and rooted. The phone has grabbed 4.3 and is waiting for me to start the update. I know that once I do, I'm going to lose root acces though. I want to keep the phone rooted. However, I no longer have access to a pc of any sort. Is there anyway to root the phone using the phone itself? My phone is the ONLY computer like device I currently have.
