Hi,

***

This can be useful to correctly specify the branding when making FTF files with Flashtool, to identify FTF files if the branding has not been (correctly) specified by the uploader and to download a different firmware customization with Sony PC Companion.

The lists are sorted by region. Look up customization numbers or SI numbers easily by pressing Ctrl-F (Windows/Linux) or Command-F (Mac).

Branding: carrier name or "Customized" for unbranded devices, followed by the ISO code of the country. Enter this into the "Branding" field when creating an FTF file with Flashtool.

Cust. no.: customization number, can be found in your service menu (dial *#*#7378423#*#* > 'Service info' > 'Software info' > 'Customization Version').

SI number: Sales Item, can be found on your box and perhaps on your receipt, but not on your phone. There are multiple SI numbers with the same customization, because every color (black/white/purple) has its own SI number.
