In this guide, we'll show you the steps to disable and bypass DAA and SLA authentication on Xiaomi, Poco, and Redmi devices. Although the last two are no longer part of their parent company and are now an autonomous entity, this is where their differences end. All three companies have an impressive set of devices that handle custom developments.

Once the kernel source code is released, there is no end to the custom binaries and modifications you can experiment with. This includes installing TWRP, custom ROMs or rooting via Magisk.

Fortunately for MediaTek devices of the aforementioned brands, there was a useful way out.

However, there is a useful workaround to get around this limitation, and in this guide we will tell you exactly that. So let's check the steps to bypass DAA and SLA authentication on Xiaomi, Poco and Redmi devices.

What are DAA and SLA authentications

Many OEMs ship their devices with a locked bootloader to prevent users from straying from stock offers.

With the addition of Download Agent Authentication and Serial Link Authentication, users can have difficulty unlocking their devices. But, why?

The above two security mechanisms now only allow authorized users to perform the flashing process on bricked devices. It performs a check comparing the decrypted string with the user's account. If it finds that the user account does not match the authorized Mi account, it will not allow you to proceed with the flashing process.
