Realme X3 SuperZoom gets unofficial bootloader unlock method, while Realme C3 receives it officially
Realme usually ships their phones with an unlockable bootloader, but you can’t simply use a typical Fastboot unlock command to accomplish the task. Unless you’re dealing with the Realme 2 or C1, you have to first install a model-specific app known as In-Depth Test to validate the eligibility of bootloader unlocking. The app sends a bunch of unique identifiers from the target device to Realme servers in order to generate an unlock token. After a successful server-side validation, the app itself installs the token on the phone, and then only you can proceed with
fastboot flashing unlock to carry out the remaining unlock process. However, it seems that an existing In-Depth Test app can be forced to run on an unsupported model in some cases. The “hack” is stable enough to unlock the bootloader of the Realme X3 SuperZoom.
While reviewing the Realme X3 SuperZoom, our very own Zachary Wander, better known in the forums as XDA Recognized Developer Zacharee1, has discovered that the In-Depth Test app intended for the Realme 6 Pro can also be used to perform the bootloader unlocking on the X3 SuperZoom. The app might throw some errors regarding device incompatibility, but you can easily change the region settings on your Realme X3 SuperZoom to bypass them. Unlocking the bootloader will factory reset your device, but it’s absolutely essential if you wish to root your device.
According to Zachary, the trick might work on the regular Realme X3 as well, while we can spot conflicting reports of Realme 6 bootloader unlock using the same app. The OEM has yet to publish the kernel sources for the Realme X3 series, thus don’t expect a source-built custom ROM for the device duo at this moment even if you manage to unlock the bootloader.
The Realme C3 has also gained bootloader unlocking support, albeit via the official channel. The company published the kernel sources for this device back in April, and now finally they have released the In-Depth Test APK for the Realme C3. We hope that the availability of the kernel source and the bootloader unlocker app should be useful to kickstart development on this phone.
