I have a Galaxy S3 SGH-i747 that has the broken/stuck power button. It's on 4.1.x at the moment, the OS that originally came with it. It will eventually, after some finesse, boot up into a useable phone state, as long as the power button is avoided. I wanted to update to some variant of 4.4.x or even 5.x in the future, and wanted to ask if I can do this without touching the power button. I am able to install root. Everything I've read seems to involve going into the recovery menu which eventually requires having to press the power button. Thanks.
