You have to Upgrade the EROM and the SW. It's done by service software only, something like setool and cruiser tools.Search on google for setool and cruiser.

I think there is a setool lite version who can help you solve the problem for free just by reflashing the SW of the device.

Try changing another SIM card to test it. Place the SIM inside your phone in such a way that the SIM terminals comes into contact with the terminals present in the terminal.

Software problem

try to put charger to phone and see whether it shows charging. if it shows charging than you can power on after a while. are if you have removed battery without switching off the phone to change sim card, than most probably your phone's software got crashed and you need to visit sony ericsson service point.
