A 6.53-inch IPS screen with 1080 x 2340 pixels and 24-bit colour is provided on the display side. The camera has a resolution of 4032 x 3024 pixels, 1920 x 1080 pixels, and 30 frames per second with a 12-megapixel rear camera and a 23-megapixel front camera. There is no doubt that the selfie camera is stronger than the one on the back. A 3920 mAh Li-Polymer battery supports all of these features. Having established the specifications, here are the steps necessary to unlock the bootloader on the Vivo S1 and S1 Pro.

What is a Bootloader?

Before we dive into the process of unlocking the bootloader, it’s important to understand what a bootloader is. A bootloader is a program that loads the operating system (OS) of a device. It’s the first thing that runs when a device is turned on, and it’s responsible for initializing the hardware and starting the OS.

Why Unlock the Bootloader?

You can install custom ROMs on your Vivo device after unlocking its bootloaderroot it, and perform other advanced customizations that aren’t possible when the device’s bootloader is locked. Additionally, custom recoveries can be flashed, which can be used to back up your device, update software, and so on.

Downsides of Unlocking the Bootloader

The biggest disadvantage of unlocking the bootloader is that your device’s warranty will be voided. Why do manufacturers do this? There is a simple answer to this question. OEMs ship their devices with a locked bootloader, which prevents users from using anything other than the stock operating system that comes pre-installed.

As the customized versions of the OS are launched by third-party sources such as LineageOS and Resurrection Remix, the device manufacturers do not want users to attempt to use them. As the manufacturers have no connection to these creators, they dissociate themselves by voiding the warranty.

In addition to voiding your warranty, all data stored on your device will be lost. In addition, some apps, such as Netflix, have some negative consequences as well.

In consequence, you will not be able to stream Netflix content in HD quality since the L1 Widevine Certificate has been lowered to L3. Finally, there is always the possibility of your device getting boot looped or bricked.

Important Points

  • Your warranty will be voided if you unlock the bootloader

  • Take a backup of all your phone’s data before unlocking the bootloader, as this will wipe all your data

  • You should only perform this process if you are an advanced user, and if you do not do so properly, your device will be bricked

  • In the course of the process, we are not responsible for any damage to your device

  • Make sure your PC is equipped with the most recent Vivo USB drivers

Following the discussion of the prerequisites and important points, let’s move on to the actual process of unlocking the bootloader.
