Bypass MediaTek SP Flash Tool SLA DAA Authentication

Today’s article is going to be a detailed guide on how to Bypass MediaTek SP Flash Tool SLA DAA Authentication. For those worried, if they will have to visit the Service centers in order to get their device unbricked, hold on. The solution is here. Simply follow the easy step-by-step process and you will be able to use SP Flash tool without asking for any permissions.

If you have a MediaTek device and you are skeptical about whether or not you can customize it like any Qualcomm device, then let me break it to you. Yes, you can. Thanks to the SP Flash tool that allows users to flash MediaTek devices using the SP Flash tool and unbrick MediaTek devices using the SP Flash tool.

However, the picture has changed a bit now. Earlier users could use SP Flash tool in order to use the Download Mode for MediaTek devices to flash and unbrick their devices. Yes, they can do it using the Fastboot commands too but not for hard-bricked devices.

Since the low-level Download mode could access the entire device storage, OEMs like Xiaomi and Realme have now introduced a way to complicate the flashing process – SLA and DAA. The Serial Link and Download Agent authentication require users to take permission to unbrick or flash their device from the Customer service centers.

Now, this is an issue for our tech enthusiasts. However, what you can do is Bypass SP Flash Tool SLA DAA Authentication for MTK phones. To know how, scroll down!

What is SP Flash Tool’s SLA and DAA Authentication for MediaTek devices?

SLA stands for Serial Link Authentication and DAA stands for Download Agent Authentication on SP Flash Tool. These two, as their names suggest are authentication identifying checks. This will authorize only those people to carry out flashing using SP Flash tool who have Serial Link and Download agent programs. Which further points towards Service center employees.

So in this way, you will be left with no choice but to visit the nearest service center and get your device unbricked or flashed. Quite inconvenient, right? Well not anymore, the guide below will help you in bypassing MediaTek SP Flash tool SLA and DAA authentication.

What is SP Flash Tool?

SP Flash tool is a tool from MediaTek that can be used to update or download firmware on MediaTek Android devices. You can read our comprehensive guide on the SP Flash tool here. This amazing tool can basically help you in resetting and fixing a bricked device. Other perks of this one include the ability to test device memory.

However, now the picture seems to have changed a little. In order to prevent users from using the SP tool to flash firmware and unbrick devices, the OEMs have added SLA and DAA authentication. Which means one will have to take prior permission in order to flash or unbrick their device. 

However, the reason I mentioned the change as a “little” one is that we can now bypass SP Flash tool SLA and DAA Authentication for Mediatek devices using a simple process. All thanks to senior XDA developers – Dinolek and k4y0z.

Step 3. Install Python Dependencies

If you are wondering why we have to install Python dependencies, then this is to prevent library version conflicts.

• Go to the installation directory.
• In the address bar, type cmd.
• A command prompt will launch on the Window.
• Now enter the below command in the command prompt and hit the enter key. You can also copy-paste it for your convenience.

• 

• Next, you will have to move all these files to the Python installation directory.

Step 6. Boot MediaTek device into Download Mode

Similar to Qualcomm’s Emergency Download Mode, we have a Download mode on for MediaTek devices which can be used to unbrick MediaTek device. If we have to bypass SP Flash tool SLA and DAA Authentication, entering the Download Mode is essential. Here is how you can enter into Download Mode –

• Switch off your device.
• Press the Volume Up button. However, if you have a Xiaomi device, press the Volume Down button.
• While pressing the button, simultaneously connect your device to the PC using the USB Cable.
