Listed here are complete steps to unlock bootloader on Realme 3 Pro. Realme, realizing the importance of bootloader unlock for enthusiasts, allows users to easily unlock their new 3 Pro phones. If you are unfamiliar with bootloader, basically, this is a part of your Android device which loads up the complete system software. As devices ship with locked bootloaders from the factory, users can not install custom softwares on their devices or even manually flash firmwares.

We have broken the process down into simple, easy-to-understand steps right ahead.

Just like on older Realme 2 Pro, the process for unlock is a bit lengthier when compared with other brands. But then again, not difficult if you implement the steps correctly. For the procedure itself, there are few things that need to be downloaded and installed. These include ADB / Fastboot tools and official unlock app. We will be linking these utilities for download right ahead along with any specific procedure for installation. Also, for this process, you would need your computer and preferably the official USB cable for connecting Realme 3 Pro. After unlocking, your phone will be eligible to flash custom files such as ROMs, custom recoveries and even root packages.

A few more optional tips that you should remember:

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.

5. [IMPORTANT] Copy all the backup files from your SD card to your computer as internal memory will be wiped clean while unlocking the bootloader.

If you are a developer and would want to unlock the bootloader, we recommend doing that before you set up the Google Play Store, install apps or anything because the security feature in Android clears out everything from your phone when unlocking bootloader of a phone.
