OnePlus, being a brand that caters to enthusiasts, officially supports bootloader unlocking on all its devices. However, due to security concerns and a large user base that does not intend to modify the system, OnePlus does not ship its phones with an unlocked bootloader. Instead, it provides a built-in official unlock feature that doesn’t require any waiting period. While the procedure may seem technical, we have broken it down into simpler steps to make it easy for readers to unlock the bootloader on their OnePlus 12R.

The tutorial below will walk you through the comprehensive steps necessary to safely unlock the bootloader on the OnePlus 12R. However, before we delve into the tutorial, let’s explore the advantages of unlocking a bootloader on any Android phone. Understanding these benefits will provide a clearer picture of why this process is often undertaken by Android users. Let’s get started!

The bootloader of your OnePlus 12R is an integral part of the core Android system. It initiates the kernel and is responsible for booting up your device. In addition to this, it also safeguards the device by ensuring integrity through the verification of the boot and recovery partitions.

Benefits of Unlocking Bootloader

Unlocking the bootloader of an Android device opens up a world of possibilities for Android enthusiasts or super users. It’s indeed the first step to perform for those who love to use root apps from the Play Store. Here are some key benefits of unlocking the bootloader:

1. Custom ROMs: Unlocking the bootloader allows you to install custom ROMs on your device. These ROMs can offer features not found in the stock version of Android and can even improve device performance.
2. Root Access: With an unlocked bootloader, you can gain root access to your device. This gives you full control over your device, allowing you to make changes to the system files, overclock your CPU, and more.
3. Latest Updates: Sometimes, manufacturers stop providing updates for older devices. With an unlocked bootloader, you can install the latest Android updates by flashing them manually.
4. Install Recovery: An unlocked bootloader allows you to install a custom recovery like TWRP. This can be used to flash custom ROMs, root packages, and perform full backups of your device.
5. Remove Bloatware: With root access, you can remove pre-installed apps and bloatware from your device, freeing up storage space and potentially improving device performance.

Remember, while unlocking the bootloader has many benefits, it also comes with risks such as voiding your warranty or bricking your device if not done correctly. Always proceed with caution and make sure you understand the process and the risks involved.

OnePlus has indeed provided a straightforward mechanism to unlock the bootloader using fastboot commands. However, before we proceed to the tutorial, it’s crucial to ensure that all pre-requisites are met. This preparation is key to a successful and smooth process. Please review the pre-requisites below carefully and ensure they are fulfilled before moving on to the tutorial.

Backup your device first

Unlocking the bootloader on OnePlus 12R will indeed erase all data from your phone. This includes SMS, photos, apps, videos, games, contacts, and everything else stored in your internal storage. Therefore, it’s essential to back up all your data before proceeding with the tutorial.

There are numerous backup applications available that can assist you in this process. Once you’ve ensured that all your data is safely backed up, you can proceed to the tutorial below to unlock the bootloader on your OnePlus 12R using fastboot commands. Remember, this process is irreversible, so it’s important to be certain before you proceed.

Tips: Before proceeding with the bootloader unlocking process, ensure that you’ve copied all backup files from your phone to your computer. This is because the internal memory of your device will be wiped clean during the unlocking process. By backing up your files, you ensure that no data is lost. Once you’ve securely backed up all your data, you can proceed with the unlocking process. Remember, data loss is irreversible.

If you’re a developer and wish to unlock the bootloader, it’s recommended to do so before setting up the Google Play Store, installing apps, or performing any other actions on your device. This is because the security feature in Android wipes out all data from your phone when the bootloader is unlocked. By unlocking the bootloader first, you can avoid losing any data or settings that were added after the initial setup.
