I suggest that you contact your local support team to check if they can help you with this.

Flash Gingerbread using Flashtool:

1)  Download the rom for your device  (ver. 4.0.2.A.0.42, I mean)

2)  The rom is a .ftf file

3)  Download and install Flashtool v0.9.2.0 ( after, go to the respective folder and delete all the files you found it)

4)  Run Flashtool and follow the procedure (you have to choose your firmware)
