Downgrade Experia st27i

[robo33]

Hi

I have an Experia St27i (Experia go) that I want to downgrade to an older version because I do not like this new version.

How do I proceed to get it to work. When I use Sony PC Companion I can only update, not do an downgrade om the software.

My current version are: Android 4.1.2,  Kernel 3.0.8+, Version 6.2.A.1.100

To downgrade you need a .ftf firmware file and Flashtools as you need to manually flash your device

A selection of firmware files are here and instructions are on the download page on how to flash your device - You may also find other firmware files on XDA Developers
