How to Disable DAA SLA Authentication On Xiaomi POCO Redmi Devices

DAA (Download agent authentication) and SLA (Serial Link Authorization) is a security feature that Xiaomi Implement on their Mediatek devices to Prevent unauthorized flashing. once DAA or SLA Authentication implanted it will prevent the flash tool to write any device partition without completing the challenge.

In the case of DAA Protection, You can bypass it by loading a custom or slightly Modified DA (Download agent file) in the SP Flash tool. but in the case of SLA, You can’t load a DA File without completing the SLA challenge which is done through the Special account called Authorized MI account or ID that is given to the service center for repairing Xiaomi devices.

How SLA works
that’s simple, during the flashing, the device generates a decrypted random string if BROM (boot ROM/EDL) validates this string it allows partitions writing if not then the flash tool shows a BROM error.
