Realme GT 8 and Realme GT 8 Pro official bootloader unlocking tool now available in China

If you’ve been waiting to customize your Realme GT 8 or GT 8 Pro, there’s some good news! Realme has officially opened up its bootloader unlocking tool — known as the Deep Testing APK or DeepTesting app — ahead of schedule for the Chinese variants of these devices. This early release lets users unlock their bootloaders for deeper system access, allowing advanced modifications such as rooting, installing custom ROMs, or even tweaking system-level features for better gaming performance.

Typically, Realme makes the unlocking tool available about a month after a phone’s launch. For example, the Realme GT 8 series debuted on October 21 in China, with the unlock tool initially expected to arrive on November 20. However, Realme has now made it available early, starting November 1, to cater to users looking for in-depth performance customization.

Here’s a quick guide to unlock the bootloader on your Realme GT 8 or GT 8 Pro:

1. Enable Developer Mode: Go to Settings > About > Build Information, and tap the Build Number seven times until Developer Mode is enabled.
2. Turn on OEM Unlock: Head to Settings > System Settings > Developer Mode, and enable OEM Unlock.
3. Use the Deep Testing App: Install and open the official DeepTesting APK on your phone.
4. Start Application: Tap Start Application and then choose Submit Application. You can check the approval status later by tapping Check Review Status.
5. Unlock via Fastboot: Once your application is approved, click Start Deep Testing. The device will reboot to the START screen. Connect your phone to your PC and enter the command: fastboot flashing unlock.
6. Confirm Unlock: Follow the on-screen instructions, press the volume down key to select unlock, and the power button to confirm. Your phone will reset and reboot to the setup screen.

Important Note: Unlocking the bootloader is a powerful tool, but it comes with risks. It can cause system instability, disable certain Realme UI features, void warranty, or lead to data loss. Always back up your data before proceeding.

Realme’s decision to release the tool early reflects its growing support for enthusiast users who love to explore customizations beyond the stock experience. However, make sure you proceed carefully and understand the potential downsides before diving in.
