This repository ships a small Windows batch tool that automates the bootloader unlock procedure on a handful of Xiaomi and Redmi phones and tablets built around the Qualcomm Snapdragon 8s Gen3 or Snapdragon 7+ Gen3 chips. The README is in Chinese and the repo has 14 stars. No primary language is detected since the project is essentially a collection of .bat scripts and per-device configuration folders. Unlocking the bootloader, often shortened to BL unlock, lets the phone owner load software that the manufacturer does not normally permit. Xiaomi keeps this process behind an official wait period and account check, and this tool sidesteps that wait by taking advantage of a flaw in older builds of Xiaomi's HyperOS. The author lists four devices that the script knows about: Xiaomi Pad 7 Pro, Xiaomi Civi 4 Pro, Redmi Turbo 3, and Xiaomi Pad 7. The tool only works inside a narrow software window. The phone must be running HyperOS 2.0 or later, since HyperOS 1.0 does not include the underlying service the exploit relies on. The security patch level must also be on or before the first of February 2026, because Xiaomi closed the SELinux path used by this method in a patch that landed after that date. Usage is presented in four steps. The user enables developer options, USB debugging, and OEM unlocking on the phone, signs out of the Xiaomi and Google accounts, and disables Find My Device. Then on a Windows 10 or 11 PC they unzip the toolkit and double click the main unlock script, followed by a status check script and an ADB and Fastboot helper for debugging if needed. The README warns that unlocking the bootloader wipes all user data, recommends a rear USB 2.0 port and an original cable, and disclaims any responsibility for bricked devices or data loss. Bug reports are welcomed as GitHub issues with screenshots.
