correct firmware

[Nations112]

Good day.
On baterry I have written Sl 1257-6719
But the system says that the firmware 1257-7434

Is this possible?

SI is the region or where in the world it was sold or produced for

The number you need is the customization number found when you dial *#*#7378423#*#* then going to Service info then Software info - That number is what Sony reads to determine what firmware you need should there be an update

[Nations112]

in software info is

phone software version: 1252-0023

customization: 1257-7434 r8g

on battery: 1257-6719

Your customization number tells me your phone is in Poland and using Orange branded firmware which is 1257-7434

Thats normal here in the UK our SI number 1257-3114 however our customization numbers are different see below - So because we have the same SI number but different other number does not mean it's been flashed or modified - It simply lets Sony know which firware we need based on our country or place of purchase for example some bought their phones in the UK but live say in Germany their phone will still be UK orientated because of the numbers below

UK 02 1257-9042

UK Orange 1257-7799

UK Generic 1257-3921

UK Three 1257-3815

UK T-Mobile 1257-8169
