How to Disable_bypass Oppo DAA and SLA Authentication
Disable_bypass Oppo DAA and SLA Authentication

Download agent authentication (DAA) and  Serial Link Authorization (SLA) is a security feature that oppo implement to prevent unauthorized flashing on their Mediatek smartphone. Once the DAA or SLA Authentication is implanted, it will prevent the flash tool from writing any device partition without completing the challenge.

In the DAA Protection case, 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 oppo ID or an account given to the service center for repairing oppo devices.

How the SLA works:

That’s simple, during the flashing process, the device generates a decrypted random string; if BROM (boot ROM/EDL) validates. This string allows partitions writing; if not, then the flash tool shows a BROM error.
