DA file in such a situation rewrites the user partition of the mobile and restores the system. Some tools verify the checksum before flashing, which fails in encrypted mobile. DA file gives permission to the tools to complete flashing with this bypass. Having a custom DA file for Infinix S5 X652C mobile is also important because the common DA file does not work on some secure chips. The specific DA file for each brand or model is the key to the success of flashing.
Finally, if you want to do a full system restore of your Infinix S5 X652C mobile, then the DA file is a basic requirement.
