Hello

Can I download the official firmware on your phone 15.2.A.1.12 ?

Do not like Android 4.3 - 15.5.A.1.5

Or give the choice to choose the firmware "Sony PC Companion 2.1"

thanks for the help:)

flashtool it does not see

That site is for developers who make custom Roms - To downgrade etc you can either look for a .ftf firmware file on XDA and manually downgrade etc using Flashtool or if available create your own and maually flash (Ignore the title but do follow the guide)

The same issue - due to "improved blurring" in camera module I wish to downgrade back to 4.2.2: 15.2.A.2.5 DE - German Undranded, but all I could find up to now were with other customization/region. I understand that generally there are quite the same, but need to keep region as it is. Has anybody this stock ROM or a link to such? Links at XDA and MrCrab (and several others) lead to Indonesian while stating it is German, alas. Mentioned XperiFirm gives results for the very last stock versions only. Probably SONY keeps these older ROMs available for download in another place? If yes, where?
