MTKSU CRITICAL INIT STEP 3… STABLE.
This error usually occurs during the initial stages of a bootrom (BROM) or preloader exploit. In the "mtksu" context—often associated with gaining temporary root or unlocking bootloaders on MTK chipsets—Step 3 represents the point where the tool attempts to overwrite specific memory addresses to bypass security checks.
In simple terms, mtk-su is a clever piece of software that uses an exploit (CVE-2020-0069, a memory vulnerability in MediaTek drivers from 2019) to grant root access on devices with a locked bootloader. This error means that the very first checks the program performs to set up its environment have been blocked by the device's security system. It fails right at the start, before the program even gets a chance to run the actual exploit code.
Look for a permanent rooting method (unlock bootloader + Magisk/KernelSU) or accept that your device isn’t vulnerable to MTK-SU. mtksu failed critical init step 3 best
If the above solutions fail, your device’s security patches are likely the bottleneck.
Manually supply the --offset parameter.
The error is essentially a security mechanism doing its job. However, by using the latest binary , setting correct permissions ( chmod 755 ) , and ensuring a stable ADB/Terminal environment , you can usually bypass this check. MTKSU CRITICAL INIT STEP 3… STABLE
command and try running the exploit again; it may succeed on the second or third attempt. Check File Location : Ensure the binary is located directly in /data/local/tmp/ . If you pushed it into a subfolder (like /data/local/tmp/mtk-su_r12/ ), move the binary to the root of and try again. Update the Binary
: Open your Android settings, navigate to Apps, select MTK Easy SU , and choose Clear Data and Clear Cache .
This command temporarily switches SELinux to permissive mode. After executing it, immediately try running the MTKsu rooting process again. In simple terms, mtk-su is a clever piece
If it says arm64-v8a , use the mtk-su file from the arm64 folder. If it says armeabi-v7a , use the arm version. 3. Ensure Proper Permissions and Location mtk-su must be run from /data/local/tmp . Steps: adb push mtk-su /data/local/tmp/ adb shell cd /data/local/tmp chmod 755 mtk-su ./mtk-su 4. Use -v for Verbose Output
When the execution fails at Step 3, the tool has successfully recognized the hardware but failed to inject the payload or hijack the necessary system structures.
