MediaTek chipset-powered devices are grabbing the mobile market really well due to the slightly affordable price range and they’re well optimized too. MTK devices do have a BROM (boot read-only memory) that basically loads the preloader executable and boots the Android system. Here we’ve provided you a full guide to Bypass MediaTek’s SP Flash Tool Authentication Protection or Disable DAA and SLA auth file.
MTK devices also have an alternative booting method which is known as ‘Download Mode’. The Download Mode or EDL (Emergency Download Mode) basically used to unbrick devices such as Qualcomm chipset-enabled devices. Whereas MTK devices use ‘SP Flash Tool’ for flashing system files quite easily. Due to the low-level download mode, the chances are high that users may have to flash firmware via download mode using a signed ‘Download Agent’.

Here Download Agent can be only used if it’s officially signed or authorized by the particular device OEM. In a simple line, you can’t flash firmware or unbrick most of the MTK devices using a Download Agent unless the manufacturer has set permissions for it. A huge thanks to XDA Senior Member xyz and developers Dinolek & k4y0z for making it possible to easily bypass the MediaTek’s SP Flash Tool SLA and DAA Authentication whatsoever.

What is SP Flash Tool’s SLA and DAA Authentication for MTK Devices?
As we’ve already mentioned above, MediaTek devices also have the Download Mode just like Qualcomm’s EDL mode. This download mode is used by support employees or officials to forcefully flash the stock firmware or unbrick MTK devices to get back into the normal status again. Although these days advanced users are also capable and aware enough to flash firmware or repair software files using the SP Flash Tool.
It’s a popular flashing tool for MediaTek chipset-enabled devices to easily unbrick MTK devices or flash the stock firmware again after booting into the Download Mode. Unfortunately, OEMs are preventing users to do so by putting “Serial Link Authentication (SLA)” and “Download Agent Authentication (DAA)” process.
Therefore, it becomes quite hard for the users to authorize DAA or SLA program while flashing the firmware on MediaTek devices. That means if in case, something goes wrong with your MTK device software then you’ll have to rush to your nearest authorized service centers to flash the stock ROM again. But there is a possible workaround to do so by following the full methods below.
List of compatible MediaTek processors:
It’s highly recommended to check out the compatible MediaTek chipsets below so that you can ensure whether your MediaTek chipset-enabled device is supported by this method or not.
Please Note: According to XDA, all the listed SoCs are currently supported for this process. But interested users or developers should have to code a suitable payload first to disable the BootRom Protection Routine.
