Z3 not booting/charging after failed update

The latest FW update for my Xperia Z3 compact (v. 23.0.1.A.5.77) for some reason failed. There was not enough battery so the PC Companion was complaining. I've charged and tried again. The phone kept finidng some sort of recovery and powering itself off. 

Now, if I power it ON it shows this big message that update has failed and that I should connect and try again. I connect the USB to my laptop. First of all it doesn't even want to power ON. It can only power ON with disconnected USB. If I disconnect, it powers ON. But then displays the message listed above and shuts down.

How to resolve this?

By using the "repair"  funcion of PC Companion i managed to "force" an update. Note that you have to select the right version of Z3 and that you will loose data such as contact lists. Also be careful to follow the instructions given by PC Companion!

It took me about an hour to solve this....to be brief I ended up deleting all my data..
