Disable or Bypass DAA and SLA Authentication on Xiaomi, Poco or Redmi devices

In this guide, we will show you the steps to disable and bypass DAA and SLA Authentication on Xiaomi, Poco, and Redmi devices. While the latter two are no longer part of their parent company and are now a standalone entity, but this is where their differences end. All three companies have an impressive set of devices that are ruling the custom developments.

Once the kernel source code gets released, there’s no end to the custom binaries and modifications that you could try out. These include installing TWRP, custom ROMs, or rooting it via Magisk. But these tweaks aren’t without risks. There’s always a chance of the device getting bricked if you don’t perform the steps correctly. Fortunately for MediaTek devices from the aforementioned brands, there was a handy way out.

You could flash the stock firmware via SP Flash Tool and your device will be up and running. But as of now, this seems to be a distant possibility due to the introduction of DAA and SLA. However there does exist a handy workaround to bypass this limitation, and in this guide, we will make you aware of just that. So let’s check out the steps to bypass DAA and SLA Authentication on Xiaomi, Poco, and Redmi devices.

What are DAA and SLA Authentications

To prevent users from deviating from the stock offerings, many OEMs ships their devices with a locked bootloader. However, they still give users an option to bypass this restriction by unlocking the device bootloader. But there is no option as such when it comes to flashing firmware on a bricked device. With the addition of Download Agent Authentication and Serial Link Authentication, users might have a tough time unbricking their device. But why is that so?

Well, the above two security mechanism now only allows the authorized users to carry out the flashing process onto bricked devices. It performs a verification check by matching the decrypted string with the user account. If it founds out that the user’s account isn’t matching with the Mi authorized account, then it wouldn’t let you carry on with the flashing process. But you could now keep all these worries to rest, as it is now possible to bypass DAA and SLA Authentication on Xiaomi, Poco, and Redmi devices. Let’s check out the required instructions for the same.
