Update Samsung Galaxy S8 Plus to Android 8.1 Oreo via Resurrection Remix Firmware

As you know Samsung released the official Android 8.0 Oreo OTA update for the Galaxy S8 Plus. But, during the same day the company also stopped the roll out due to some internal problems, which means that the latest Android build is still nowhere to find. Of course, the OTA will be soon resumed, but until that happens you can test and try a custom ROM firmware that’s based on Android 8.1 Oreo. And you should choose a custom ROM package especially if you are that kind of user who is always ready to try new tweaks and customizations.

Well, in that respect you can use the new Resurrection Remix software. This custom ROM is powered by the latest Android 8.1 Oreo OS so you will manage to update your Galaxy S8 Plus without hassle. The software is developed by those of xda-developers and represents a free aftermarket distribution of stock Android system. So, you are going to lose your phone’s warranty if you choose to flash this unofficial Android platform. Anyhow, we will discuss about the risks involved in a few moments.

Until then, you need to know that the Resurrection Remix ROM is stable and smooth. The Android 8.1 Oreo ROM will run without problems on your Samsung Galaxy S8+ even though the OS is still under development stage – however, in rare situations you can experience some minor issues such as screen freeze, hangs, bugs or similar other malfunctions. But, bottom line, with this Android OS installed your S8 Plus will run better and faster as the custom ROM is light and extremely fast. Moreover, the battery life will be upgraded and you can use different other tweaks and customization options.

As already mentioned, the warranty of your device will be lost. That is happening because during the update operation Samsung KNOX will get tripped. So, access to some built-in apps might be also restricted during the flashing process. Therefore, if this aspect scares you, you shouldn’t complete the guidelines from below. However, the warranty can be restored but only in some conditions – only by reinstalling the stock Android firmware by using Odin.

Additionally, a hard reset will be applied – the new custom ROM cannot run unless the internal storage system is wiped out. Therefore, if you are not careful enough you can lose some important files – mainly, everything that wasn’t there from day one will be erased. So, a backup shouldn’t be optional especially if you want to secure your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, EFS folder, calendar info, IMEI / NVRAM data and so on. This backup can be easily applied on the Galaxy S8 Plus: you can sync your files with your Google Account, you can use dedicated backup and restore apps from Google Play or you can just use built-in cloud storage services.

The Resurrection Remix firmware is a custom ROM so it will be different from what you are currently using on your Galaxy S8+. Therefore, you might end up in thinking that the stock OS was actually better, situation during which you will try to go back to stock. Thus, a Nandroid backup should help you in this respect – the Nandroid backup operation is saving the stock Android firmware so this package can be afterwards used if you want to go back to stock.

For the Resurrection Remix flashing process you will have to use a computer. There you will save the required files – your smartphone and its USB cable must be there too. On your phone the Developer Options field must be enabled – from Menu – Settings – About Phone tap repeatedly, for 7 or 10 times, on Built Number (do that until the ‘you are a developer’ message is displayed). Then, from Developer Options (you can access it from Menu – > Settings) you have to check the ‘USB Debugging’ field.

You need to root your Samsung Galaxy S8 Plus. The root operation will unlock your device, an important aspect as a custom ROM can be applied only if it can access, modify and customize the Android core system. Additionally, a custom recovery image must be used on your handset. I recommend you to use TWRP recovery in order to avoid any sort of problems – do note that a custom ROM can be applied only if a custom recovery environment is used.

Finally, verify the power that’s left on your Galaxy S8 Plus. This power should be higher than 50% – otherwise your device can remain without juice right while the Android 8.1 Oreo firmware is applied. Unfortunately, if a sudden shut down occurs, different malfunctions might be caused within the Android core system. So, be careful and try to keep everything safe and secured – just plug in the charger first, if that’s required.
