: Users have reported that the exploit is occasionally unstable and may fail randomly on the first few attempts. about.gitlab.com Potential Fixes and Workarounds Re-issue Permissions : Ensure the file is executable. Users on suggest running chmod 755 mtk-su
The tool works by abusing a kernel driver called the MediaTek Command Queue (CMDQ). In simple terms, this driver handles direct memory access (DMA) for hardware tasks. A bug in how it handled certain commands allowed unprivileged users to write to arbitrary physical memory, making a privilege escalation to root trivial.
Ensure you have given the file executable permissions by running chmod 755 mtk-su before execution.
adb push mtk-su /data/local/tmp/ adb shell cd /data/local/tmp/ chmod 755 mtk-su ./mtk-su Use code with caution. Downgrade Your Firmware
chmod 755 mtk-su ./mtk-su -v
Confirm you have set the correct permissions with chmod 755 mtk-su before running it.
