Xperia Z1 c6903 i can't repair with PCC error 302

[joreargento]

Somebody know solution this error, my win is win 8 pro. I've installed Xperifirm 4.7.2 and Flashtool 0.9.18.6, i think no problem in usb driver, because i can install any firmware. I installed to test various firmware (eg US and EURO) , causing IMAI and baseband stay in unknown in device.
I am in Argentina my device is c6903. Which firmware i must install? for recovery IMEI and baseband? because I cant find in the Xperifirm ftf belonging to this country, you may need to install another country and then stepping borrar firmware without baseband?
Thanks.

It can't be done, this is a hardware restriction rather than software.
