DAA acts as the second wall. The Download Agent (DA) is a small program sent from the SP Flash Tool to the device's RAM to manage the actual reading and writing of the flash memory. DAA requires the DA file to be cryptographically signed by the original equipment manufacturer (OEM). Without a valid signature, the DA file will be rejected, and the flashing process is halted.
Always ensure you use the correct firmware for your specific device model to avoid permanent damage. If you'd like, I can: Provide links to the latest List specific Xiaomi models this works for
This open-source exploit bypasses secure boot across a wide array of legacy and modern MTK chipsets, including but not limited to: (Legacy Entry-level) MT6750, MT6753, MT6755, MT6757 (Mid-range Legacy) MT6761, MT6763, MT6765, MT6768 (Helio A22, P23, P35, G35) MT6771, MT6779 (Helio P60, P70, P90) MT6781, MT6785, MT6789 (Helio G96, G90T, G99)

While the exact process varies by tool, the general workflow is consistent:
MediaTek is closing the BROM exploit that tools rely on. Starting from and newer, BROM includes:
By bypassing the "Serial Link Authentication" (SLA) and "Download Agent Authentication" (DAA), you regain full control over your MediaTek hardware. This method is compatible with a wide range of SoCs, from older MT6580 chips to newer Dimensity series. How to use MTK Bypass to backup or flash secure boot MTK Without a valid signature, the DA file will
Right-click the executable file ( .exe ) and select .
Note: You must act quickly, as MTK devices only stay in BROM mode for a few seconds before switching to preloader or charging mode. Step 3: Run the MTK Auth Bypass Tool
It sounds like you’re looking for a way to bypass on MediaTek (MTK) devices — often needed when the tool shows errors like STATUS_SEC_AUTH_INVALID or SECURITY_SBOOT_AUTH_FAIL while trying to flash a device with a locked/preloader authentication.
Watch the LibUSB device list closely. As soon as MediaTek USB Port or Preloader appears, select it and click . Disconnect your phone. Step 2: Run the Auth Bypass Tool Extract the downloaded MTK Auth Bypass Tool folder.
Bypassing authentication (Auth Bypass) in flashing tools is typically used to flash custom ROMs, fix bricked devices, or remove bloatware. However, this process often voids warranties, can violate software license agreements, and carries a significant risk of permanently damaging your device (bricking).
