I have tried backing up my phone to my computer with Sony Xperia companion but get the enclosed screen messages. I restarted my phone but still get error messages.
Can you try to transfer the data to the computer without using Xperia Companion until you reset the device?
How do I do this?.
Try these steps and check:
To back up files to your computer
I've done this but still can't sign into my google account from Sony Xperia companion or from my phone to backup files to my google account. I still get the same error message as above.
Yeah, that's why you need to perform factory data reset to solve the issue with the Google account on your device.
I can't connect to my google account on my device even after performing a factory restore.
Do you still get the same error message after the factory data reset?
Yes I do.
Can you try the exact instructions in this link to perform software repair without asking you about the Google account thing?
