In this guide, we will show you the detailed steps to unlock the bootloader on your Galaxy S9/S9+ devices. Both these devices were the most anticipated ones four years back when they first made their way. And it’s fair to say that the hype is yet to settle down. Launched with Android 8 out of the box, they received their fair share of two years of promised OS upgrades. Android 10 based on One UI 2.5 was the last OS update that these devices were officially blessed with. However, in custom development, these devices are still one of the most popular players out there.
So much so that they have even received the latest Android 12 update based on One UI 4.1. Likewise, there is also a couple of custom recoveries in the form of OrangeFox and TWRP. Apart from that, you could gain administrative privileges by rooting your device via Magisk. But before you could carry out any of these tweaks, you have to checkmark an important prerequisite off the list- the bootloader on your Galaxy S9/S9+ needs to be unlocked. And in this guide, we will show you how to do just that. Follow along.
Benefits and Risks of Unlocking Bootloader
Unlocking the bootloader is the gateway to extract the maximum benefits of Android’s open-source ecosystem. For example, you will be able to install a custom ROM or flash a custom recovery like TWRP. Likewise, you will also be able to get access to the system partition as well as administrative privileges by rooting your device via Magisk. This will then allow you to flash Magisk Modules, Xposed Framework , Substratum Themes, Viper4Android among others.
However, carrying out these tweaks brings in a few uninvited risks as well. To begin with, it will wipe off all the data and could nullify the device’s warranty. Along the same lines, it will trip the Knox counter, thereby apps like Samsung Pay and Secure Folder might not function. The SafetyNet will be triggered as well [FIXED], thereby preventing you from using banking apps [FIXED]. So if that’s well and good then let’s get started with the steps to unlock the bootloader on Samsung Galaxy S9/S9+
