After flashing a firmware with flashtools, I lost my network signal. I used the xperia companion, flashed again with flashtool, but don't worked.

I think this happening when I flashed with simlock.ta (un)checked... I don't remember.

How can I fix this/? Please.

If you do not have trim area backup from working state - only customization in authorized Sony service centre can help or main board swap from working phone.
