I am new to all this, techy stuff, and have recently bought a htc one m8. I had it rooted for me, but I didn't want to pay for GPE. I then found out Lollipop has been released, and tried to get it by going into software info on settings, but I couldn't get the lollipop update, as my phone says 'Your phone software is up to date with the latest version'. I realised that because of my root, my phone wasn't on the same channel as it was on before. I found another way to get lollipop, but that meant buying sunshine for $25. Is there another free alternative? I thought I could unroot my phone, then reroot it, but I do not know how to unroot, get update then reroot. Can I please get help?
