Bypass the extra HyperOS account binding step so you can proceed with bootloader unlocking on a Xiaomi device.
Study how the Xiaomi HyperOS bootloader unlock API vulnerability works at the protocol level.
Unlock a Xiaomi, Redmi, or POCO device running HyperOS to install a custom ROM or recovery.
Requires PHP 8.0+, Android platform-tools (adb), and a USB-connected Xiaomi device running official HyperOS firmware.
Xiaomi-HyperOS-BootLoader-Bypass is a proof-of-concept tool that exploits a vulnerability in Xiaomi's HyperOS to bypass the account binding restrictions Xiaomi added for bootloader unlocking. Bootloader unlocking is something Xiaomi device owners sometimes want to do to install custom operating systems or gain deeper control over their phone, but Xiaomi added extra restrictions in HyperOS that make the binding process harder to complete. This tool works around those specific restrictions. The tool is written in PHP and uses the ADB (Android Debug Bridge) protocol via a companion PHP library called php-adb. To use it, you need PHP 8.0 or later installed on your computer, along with Android platform tools that include the adb binary. The script communicates with your phone over a USB connection. To qualify for the bypass, your device must be an unbanned Xiaomi, Redmi, or POCO phone running the official HyperOS firmware, with a working SIM card. You also need a valid unbanned Xiaomi account. Xiaomi's standard MIUI restrictions (such as waiting 168 or 360 hours after binding) still apply after using this tool, the bypass only removes the extra HyperOS-specific binding restrictions, not the base waiting period. The README includes a detailed warning section. Unlocking the bootloader voids the device warranty and any extended warranty programs. It can permanently damage Trust Execution Environment features in a way that cannot be repaired without replacing the motherboard. Data on the device may be lost. The device or account can be banned by Xiaomi. Anyone using this tool accepts these risks themselves. The license is proprietary: the author allows use of the tool but reserves all rights, and copyright notices cannot be removed or changed.
