Result: Preloader’s g_auth_required flag flips to 0 , disabling all remaining authentication checks.
: Run the utility (e.g., python mtk payload-bypass ). Once you see "Protection disabled," you can safely use the SP Flash Tool in UART mode to flash your firmware. Benefits of Successful Bypass
To achieve a "better" result—meaning a stable, safer, and more reliable bypass—you need to understand the shift from older BootROM (BROM) exploits to the modern Preloader-based methods required for V6 chipsets. Why the MT6789 Is Different mt6789 auth bypass better
When MediaTek released the (Helio G99), they introduced the V6 security protocol . This was a major upgrade designed specifically to "patch the hole." The V6 BROM is hardened against previous exploits, effectively slamming the door shut on the easy bypass tools that worked for older V5 chips. The Community Strikes Back
Highly recommended for its "one-click" reliability with newer MTK V6 chipsets like MT6789 and MT6835. TFM Tool Pro (Paid): Result: Preloader’s g_auth_required flag flips to 0 ,
While famous for older chips, newer versions (like v13) claim compatibility with V6 devices, though success rates vary compared to MTKClient . Why Bypass is Considered "Better" for Users Question: Is the security enabled mt6789 problem solved #86
: Unlike older chips (MT6765, etc.), the MT6789's BootROM is resistant to common older bypass utilities. Benefits of Successful Bypass To achieve a "better"
The cleanest method uses a known vulnerability in the preloader's USB vendor request handler. This is the "better" way because it requires no hardware modification.
