Hello,

I made a post about battery few minutes , Was wondering if i can now go back to the official firmware of the phone.  Under the battery on the phone itsefl it's this " series " SI 1246 - 9198 ,  It is possible to find this firmware and flash it on the phone?

If yes, Where i can find it ?

Thank you!

The SI is a country code or area sales code so you need the Customization number - Dial *#*#7378423#*#* then open Service info then Software info, however to answer you question you would be best visiting XDA and searching their for firmware and you will also need a program called Flashtool which you can Google and download for free
