Hi @Strat,

I'm sorry to hear about that.

Do you mean that you weren't able to repair the software using Xperia Companion? If you haven't done so already, try forcing a shut down of your device by pressing the OFF button. Once you have done that, try performing a software repair using Xperia Companion.

If the device still behaves in the same way then I recommend that you contact your Local support for assistance in having the device sent to an authorized service center for investigation.

Hi Strat,

You should still be able to perform the instructions as supplied above. Attempt a software repair using Xperia Companion and if this fails, contact Customer Care for further help.
