I tried updating the firmware on my X6 using NSS and then the update feature on Ovi but now the phone won't start properly.

The new software downloaded and looked like it installed properly but during one of the reboot stages it wouldn't start up properly. I have a feeling it's due to the battery being low, because now when I plug the charger in I just get screens with different colours fading in and out and nothing else.

My computer won't recognise the phone being connected to it.

Anyone have any ideas what to do now? Can it be salvaged?
