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
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
what about mine ? 1257 - 8082_R6G
Generic Trade Middle East North Africa - Latin AKA
Nozomi Customized MEL (Middle East Latin)
I want my phone to claim, but the box and baterry is 1257-6719 but in the phone. 1257-7434
i didnt flash.
no problem?
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
