So I got a old S3 laying around. My main phone broke so I'm using this until I can get it fixed. I was wondering what is the chance that if I root and install lollipop on it that I will brick it? I want to install a lollipop ROM, but because its my main phone right now I don't want to brick it. Also, if I want to can I uninstall the ROM and un-root? Or is it stuck rooted permanently? Thanks in advance!
