version 6.1.A.4.45

Hi, I have been told by O2 carrier to update my xperia J to software version 6.1.A.4.45, 1257-3921_R6G (I lost the previous firmware)

I have searched in the developer page

http://developer.sonymobile.com/downloads/all-android/

but I cannot find this version.

In addition when I use the Sony Upadte Service program it installs a generic version of 11.0.A.7.5 and I get an "invalid sim" message so the phone cannot connect to any network...

Please advice me on how to find and install the appropriate version so that I can use my phone again.

P.S. I am currently not living in the UK where O2 phone was bought so I guess the sony update service chooses the generic world version to download.

Different customizations have different build numbers. If you have a operator customized phone this phone will most likely also use a operator customized build of the software. This build is not necessarily the same as generic ones.

But if you haven't flashed your phone using any unofficial tools you will be able to update or reinstall the latest version of the software for your phone model using PC Companion or Update Service.
