I flashed my phone using phoenix and downloaded the firmware files using navifirm. It is common knowledge that using phoenix to flash your phone automatically assigns your product number into what the navifirm firmware file product number was used. After that process was done I used nss to change back my original product number.

I was just wondering, the firmware file product number that was used in navifirm was different as opposed to my original product number. Since FOTA uses my original product number to upgrade would it cause a problem in the future if I upgrade using FOTA since my firmware file product number that is installed in my phone has different product number with the firmware files that are to be downloaded in FOTA in the future?
