repeat the update process, perhaps the SIM card its faulty, remove the SIM card and try to access your phone w/o the SIM card

thanks for the respone. I managed to reset my phone to factory default. It took a few attempts as the device USB connection was not recognised by my PC but it eventually worked.

Thank you for the replies.  I am unable to start the phone at all. Now it's showing a red light, wich means it's charging, but I'm still unable to do anything. It won't even appear in Device Manager. I'm using Windows 8 64 bit.

I am waiting for prepare, but I don't know anything about the phone: battery status etc. Also, the SIM card is a brand new one and it works on other phones, even with a SIM adapter (Allview Simply S5 - backup phone works very well).
