I have Xperia S (LT26i). Earlier it had 6.2.B.0.211 installed.

I flashed it with "XperiaS_LT26i_6.2.B.1.96_1257-6919.ftf", flashing was successful, but after I started my phone I saw this message "SIM network unlock PIN". What should I do now?

  • That means your phone was locked already by service provider... There might be a tool to get unlock code or skip the lock... You have to search on this... Jul 8, 2015 at 5:03
