Important Information

An unlocked bootloader will certainly give you more freedom and control over your phone’s software, but it also comes with some risks. So before you head down to the instructions, make sure to read the information listed below.

First, any damage caused by installing custom ROMs, rooting, etc after unlocking the bootloader may have an adverse effect on the phone’s performance and could even damage it. Such actions and their outcome are not warranted by Realme.
You will continue to receive official Realme UI OTA updates on your phone after unlocking the bootloader. But this is only applicable until you have made any permanent modifications to software or device partitions, like installing TWRP custom recovery, rooting, etc.
If you manage to brick your phone while flashing ROMs, mods, etc, you can attempt to restore the stock firmware using the Realme Flash Tool. Or, you can alternatively get it restored from an authorized Realme service center free-of-charge.
Once the bootloader is unlocked, the Widevine status of your Realme X50 Pro will be changed from “L1” to “L3”. This means you will not be able to stream HD content on streaming apps like Netflix, Hulu, Disney+, Amazon Prime, etc. Although if you have rooted your phone, you could use a Magisk Module to restore back Widevine L1.

Requirements

Unlocking your phone’s bootloader will erase all the data including that stored on the internal storage. Don’t forget to take a backup. Refer to our guide on how to backup data on Android Devices.
Keep your device charged sufficiently (at least 50% is recommended) so that the complete process is carried out smoothly.
Make sure that you have installed all the latest USB drivers for your Realme X50 Pro installed on the PC.
Download the latest Android SDK platform-tools (ADB and fastboot) package from here and install it on your PC (Click here for instructions).
While following the instructions, you will need to launch the command-line window in the same folder where the SDK tools are installed. When asked to do so, follow the steps below:
- PowerShell in Windows: Open the folder where ADB and fastboot are installed (e.g. C:\plaftorm-tools). Then hold the SHIFT key and right-click on an empty space inside the folder. Finally, select the “Open PowerShell window here” option.
- Terminal in macOS/Linux: Launch the Terminal window and use the “cd” command to change its directory to the folder where ADB and fastboot are installed. For example, if you installed it to /Documents/platform-tools, then you should use the following command to change the directory:
```
cd Documents/platform-tools
```
