Thanks but cannot get the phone functioning and re-formating. I have done software update through PC-companion but it doesn´t help. The phone still returns to the "Protected" mode.

Have you tried doing this...?
I have Unlocked My M4Aqua by following procedure..Give a Try..
MXTP is causing problems if we have more than one google accounts configured in the phone.
To solve the issue
1.Turn OFF your phone and turn it ON again.
2.Your phone will be turned on as normal before the PROTECTED screen appears you will have around 20 secs.
3.Go to Settings->Accounts->Google Accounts->Remove the Google Account which you have not configured with MXTP(except the one you used for activating Protection by my Xperia).
4.now when the PROTECTED screen appears Authenticate with the google account(given while activating MXTP).
your phone will come to normal mode...
better immediately deactivate this feature going to Settings-->Security--->Protection by my Xperia and then Decativate...

I am facing the same issue , i tried by removing the account but it did not work
i also tried by removing the sim card but still it did not work
i called upon helpline number they said you have to continuously type 10 times and it will open
if it doesnt you have to send it for factory settings default
