Hey /g/, I'm really stuck. I have a (Canadian) Galaxy S4, SGH-I337M and I've rooted it already. I wanted to install CM 12 on it, but there's only 11 officially available. I did find an unofficial ROM for 12 on xda-developers but I don't know what to do with it. I can't find any trustworthy/helpful guides on how to install ROMs with Lollipop. Any help?
