Thus, during this dedicated step by step guide we will detail the steps that must be followed if you want to replace the Galaxy S10 Plus software with a custom ROM platform. But, before explaining the update steps we will also review additional content such as: we will explain the custom ROM term, we will review the advantages of using a custom ROM, we will mention the risks implied and we will list the essential pre-requisites that must be first completed.

Therefore, this is the complete guide that takes you through the tweaking operation that can help you improve general performance on your Samsung Galaxy S10 Plus. Let’s see what it’s all about.

Installing custom ROMs: the first things that should be checked out

Before choosing to apply the steps from this tutorial you should be sure that you know what a custom ROM really is.

It’s a firmware, just like the stock Android OS that runs on your Galaxy S10 Plus. However, is different from the official software and comes with extra features, apps and capabilities. Bottom line, it can ensure a different Android functionality.

So, a custom ROM is a free aftermarket distribution of Android OS. It’s a ported and modified version of the stock Android firmware. Therefore, it’s an unofficial Android update developed by third party devs and which cannot be associated by any means with Samsung or with Google.

Well, as you can tell, a custom ROM cannot be OTA received. Moreover, it can be flashed on your Samsung Galaxy S10 Plus only in a manual manner that requires some additional operations too – we will discuss more about these aspects in a few moments.

Choosing the right custom ROMs for your Samsung Galaxy S10 Plus

As you will notice, there are multiple options from which to choose. At xda-developers.com you will find various custom ROMs that are compatible with your Galaxy S10 Plus. But, you need to pick wisely.

Each custom platform comes with its own strengths. Some are light and extremely fast, others are optimized for upgrading better performance and some are mixing up features that cannot be found on the stock Samsung UI.

However, you have to choose a custom ROM that’s fully stable in order to enjoy the best Android experience on a daily basis. And, some of the recommended solutions are coming from ROMs such as Lineage OS, AOKP, Paranoid Android, AOSP, or Slim ROM.

The advantages of using a custom ROM

As already outlined, with a custom ROM you can personalize the Android skin. The UI will be different from what you currently use on your Samsung Galaxy S10 Plus. You will have endless customization possibilities and various optimizations to apply.

Depending on what you want to obtain from your phone you will be able to set features and tweaks that will optimize general performance. You will be able to upgrade battery life, get rid of bloatware, gain root access, install apps that requires root privileges enabled and even overclock CPU frequencies.

Bottom line, with the right custom ROM updated, your Galaxy S10 Plus will run better, faster and smoother than it used to.

The risks that are implied

You are going to replace the stock Android OS with a custom firmware. So, you’re about to complete an unofficial update operation that’s not supported by Samsung. So, Samsung KNOX will get tripped. Shortly, you are going to lose your Galaxy S10 Plus warranty.

Moreover, during the update process a hard reset will be required. Thus, you need to be careful as otherwise you can lose your personal data, info, accounts and files. Of course, a backup is more than recommended in that regard – just save everything that might still be required afterwards before doing anything else.

Another risk is related with the ROM you choose. If it’s not compatible with your Galaxy S10 Plus, or if it’s still under development stage, you can end up in soft-bricking your Android device.

Essential pre-requisites that must be followed first

As already stated, a backup is not optional. Also, a Nandroid backup should be performed too – you can afterwards use the Nandroid backup file for going back to stock Android OS, if that’s what you will want to do.

A custom recovery image must be used. A custom ROM can be installed only from that environment, so you have to complete that process before doing anything else. We recommend you to use CWM or TWRP recovery on your Galaxy S10 Plus.

Depending on the custom recovery image you choose to use, or even on the custom ROM you want to flash, you might have to root your Samsung branded device first.

Charge your phone before starting the update process. Plug in the charger if the power left is lower than 50% as otherwise it might get turned off in the middle of the flashing operation. Sudden shut downs can damage the Android firmware, so be careful.

A computer will be needed. On your phone you have to enable USB Debugging from Developer Options. Hint: you can enable Developer Options by tapping repeatedly on Built Number – after 7, or 10 repeated taps the ‘you are a developer’ message will be displayed.
