Mtksu Failed Critical Init Step 3 Best |best| Info
This error is specific to devices attempting to gain root access via MTK-SU (a specialized root method for locked MTK bootloaders). Step 3 of the initialization process is where the exploit attempts to gain proper memory privileges. When it fails, your device either rejects the root request or soft-bricks the SU daemon.
Convert from MTKSU to KernelSU.
KernelSU does not use a memory exploit (Step 1-3). It uses a legitimate kernel module (GKI). Therefore, "Init Step 3" never executes. mtksu failed critical init step 3 best
