This project is a Windows batch script toolkit for unlocking the bootloader on a specific set of Xiaomi phones built around Qualcomm's Snapdragon 8 Gen 3 chip, running Xiaomi's HyperOS software. Bootloader unlocking is a step some phone owners take to gain deeper control over their device, such as installing custom software, but it is not something the phone manufacturer supports or encourages, and it typically voids any warranty. The README lists seven specific supported phone models, including several from the Xiaomi, Redmi, and Mix product lines. The tool depends on a specific software vulnerability that only exists on certain versions of HyperOS. It requires the phone to be running HyperOS 2.0 or later, since the vulnerability the tool relies on is not present on the original HyperOS 1.0, and it only works if the phone's security patch level is dated February 1, 2026 or earlier, because Xiaomi's own security fix released after that date closes the underlying exploit path. In other words, this tool has a closing window of usefulness tied directly to how current a phone's software updates are. Using it involves first enabling developer options and USB debugging on the phone, signing out of the Xiaomi and Google accounts, and disabling device tracking features, then running the main script on a Windows computer with the phone connected. The toolkit also includes separate scripts for checking bootloader lock status and for opening a built in ADB and Fastboot debugging environment without needing to install one separately. The documentation is written in Chinese and states plainly, in its own disclaimer, that unlocking the bootloader will erase all user data on the device, so backing up beforehand is essential, and that the developer takes no responsibility for any device damage, warranty loss, or data loss resulting from improper use. No open source license is stated in the README, and the tool is explicitly described as being for technical exchange purposes only.
