SE ARC cannot turn on

[Mirzoni]

I have some problem regarding SE ARC, i had on my phone software update, and when i was on my home wireless network i initiated that, but in time of installing that, i accidently switched my phone off. Now, i cannot turn on my phone, and on computer, PC Companion cannot detect my phone.
What should i do...

Unfortunately the software on the phone is corrupted. I'd suggest to try connecting the phone to a different PC using PC Companion but if even a different PC fails to detect your phone then you will need to contact your local Sony Ericsson service center for a possible repair option.
