Mtk-su Failed Critical Init Step 3 Access

Warning: mtk-su modifies kernel memory directly. If you continue to force it after failures, there is a small risk of causing a kernel panic, which will force the device to reboot. It will not permanently brick the device, but exercise caution.

Even on older patches, manufacturers like Samsung, Xiaomi, and Oppo often add their own security layers (e.g., Samsung Knox, Xiaomi’s MIUI optimizations). These hardening measures can interfere with step 3 by: mtk-su failed critical init step 3

Run:

cat /proc/cmdline

If you see androidboot.selinux=enforcing with extra security flags (e.g., avb), the kernel might have hardened the exploit path. Warning: mtk-su modifies kernel memory directly
