Even if you could root the phone, that's more of a work-around than a fix.

Here's what I would try...

Verify on a computer that you can login to the Google account you intend to use as the default account on the M4. Just to be 100% sure.

I don't know what account you used for this, but you said you enabled Backup and restore. Disable it.

Just for good measure, wipe the cache partition.

Turn off the phone and remove the SIM.

Factory reset the phone.

Leave the SIM out.

When you are in a location you are certain of having a good WiFi connection, power up the phone and begin the initial setup. A good WiFi connection is critical for this to succeed.

DO NOT try adding any account other than the one you want to use as the default. If you make the wrong account the device default, you'll regret it later.

With a little luck you'll be good to go.

Thanks for replying. Done all that except I am not sure how to wipe the cache partition as I gather there is no way to instal a custom recovery but the factory reset would have done that anyway.

Unfortunately the result is the same.

This was fixed when I tried with a different internet connection/ISP. Its not that I was not online before but that my ISP has dumb protocols that were stopping this from working. Thanks for your responses.
