Why is the CDA written on my product's box not included in XperiFirm?
CDA is never written on the box. The number on the box starts with "SI", which stands for "Sales Item" which is the combined identification of the device's model + color + country of origin + stock software customization, while CDA is only the customization ID.
To find out your CDA, open the stock "Phone" app and write *#*#SERVICE#*#* (*#*#7378423#*#*). This will open the Service menu.
Go to "Service info" -> "Software info" -> your CDA is under "Active Customization".
What is R1A/R3B/R3C/etc? Which one is better?
This is the operator-specific revision (officially "CDF Version") of the stock software (officially "Software Version") provided by Sony to the different regions and operators.
You can't compare revisions, each operator makes its own revisions. They are basically the same, just with different operator-specific apps.
