Question [Q] Xperia Acro HD so-03d connectivity not working.

Hi, I'm currently expierincing problems with my Xperia Acro HD. Bluetooth, Wi-Fi, sound and even signal is not working.
I cannot activate Wi-Fi and Bluetooth (it gets stucked in "activating"). Sound doesn't work at all. And the signal shows no service.
I already tried restoring with original GB rom for this device. Even with ICS. I also tried flashing Xperia Acro S JB keeping the original Baseband from Docomo ICS. All those roms showed the same issues (Wi-Fi, Bluetooth, Sound and Signal problems).
I'm starting to think that it is Hardware related. But I wan to check on you guys to see if there is any solution, other than replacing the phone

Thank you in advance!
