For those of you who want to install the Galaxy S9 Oreo ROM, Sac23’s S9 Ported ROM for your Galaxy S7 or S7 Edge, here’s a step-by-step guide you can follow. This is a guide for anyone who has a Galaxy S7 or S7 Edge model that is supported, you do NOT need to root your phone using this method (although the ROM will give you root). Installing this ROM will give you all software features of the Galaxy S9 Oreo ROM(pretty much all) as this is a “port” straight from a real Galaxy S9. Your life will change and you will be able to get S9 features without paying for it. Dead serious.
If you want to get the latest and best stock Android, you will definitely want to check out the latest Android 8.1 Oreo Resurrection Remix ROM, which is an awesome way to experience Android the way it was intended without the Samsung additives. Now, this ROM is an AOSP ROM(What is AOSP?), meaning you won’t be able to run any Samsung TouchWiz native apps like Edge panels. BUT, I absolutely feel the experience is much better on a stock Android like this and battery life/performance is much improved over TouchWiz.
