samsung galaxy s9

A new built of Resurrection Remix was released by xda junior member msdx321, who managed to port the Android 8.1 Oreo software and compile a stable new ROM on the Samsung Galaxy S9. So, shortly, now we have another update opportunity for your brand new Galaxy S9 handset. Thus, if you are ready to replace the default Samsung UI with a custom platform and experience a pure-like Android Oreo system, don’t hesitate and follow all the guidelines that are explained below.

During this step by step guide we will be describing the manual flashing operation that will add the new Resurrection Remix Oreo custom ROM firmware on the Samsung Galaxy S9. This is going to be a complex update process as you will have to use an unofficial port of the stock Android software. Shortly, there are some risks involved and some pre-requisites must be firsts ensured; bottom line, don’t apply anything without reviewing everything that’s explained here.

This release of Resurrection Remix is compatible with the Samsung Galaxy S9. The custom ROM package that’s offered below was successfully developed only for the already mentioned phone, so don’t use this tutorial if you use another handset. Moreover, the Android 8.1 Oreo based update is stable so everything should smoothly run on your smartphone. Resurrection Remix is light and fast and offers a pure-like experience – overall, this ROM should run better than the Samsung built-in firmware.

Additionally the Resurrection Remix is introducing new tweaking possibilities meaning that once this flashing operation is completed you can choose how to customize, optimize and personalize your Galaxy S9. By applying the right customizations you can bump speeds, upgrade battery life and improve general performance.

But, for achieving such advantages you must install the Resurrection Remix which is nothing but a free aftermarket distribution of stock Android 8.1 Oreo OS. Shortly, this is an unofficial platform that’s not provided by Samsung and which cannot be associated with Google. Thus, you are about to trip Samsung KNOX on your Galaxy S9, meaning that you are going to lose your phone’s warranty and the access to some built-in apps – the warranty flag can be restored only if the stock Android firmware is reinstalled, which can be done by using Odin (further detailed on that respect can be reviewed in this dedicated step by step guide).

Moreover, root access must be gained on your Samsung Galaxy S9 as otherwise you won’t be able to replace the built-in Android system. And, after rooting your smartphone you also have to install a custom recovery image such as CWM or TWRP recovery – this custom recovery environment will be required during the actual flashing process, which is detailed during the steps from below. Note: both processes indicated above are not official so do use special tutorials when trying to complete it in order to avoid unpleasant situations.

A hard reset will have to be completed during the Resurrection Remix update operation. If a full wipe isn’t applied the new Android 8.1 Oreo ROM will not run properly on your Galaxy S9. But, in our case that aspect will require your attention as you can end up in losing everything that’s important. So, as you can already tell, a backup shouldn’t be optional – choose to sync your files with your Google Account, use backup and restore apps from Google Play or use built-in cloud storage tools in order to secure your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and everything else that means something to you.

Along with that general backup you should also consider in saving the current Android OS. That is important as if the Resurrection Remix ROM will not run as you expected, you can choose to restore back to stock easily without using other complex flashing process. So, before doing anything else choose to make a Nandroid backup on your Samsung Galaxy S9.

And since we are discussing about a manual flashing process it will be a great idea to review the list of general pre-requisites that are resumed just below:

  • A computer must be used as there you will have to save the Resurrection Remix Oreo firmware package.
  • On your Galaxy S9 you need to gain developer options. That can be done easily by tapping repeatedly on Built Number – after 7 or 10 taps your device should return the ‘you are a developer’ message.
  • Access Developer Options (it should be available under ‘menu – > settings’) and from that field check the USB Debugging feature.
  • Make sure that your phone and its USB cable are near you as a connection between your phone and your computer will be required.
  • You need to charge your Galaxy S9 if the power left on your handset is lower than 50% – otherwise your device can get turned off right in the middle of the update operation.
  • Note: if a sudden shut down do occurs you can end up in soft bricking your SGS9 so make sure you avoid such unpleasant situations.
