Thanks for everyone's attempts to help I'm just a normal user. I'm not interested in VIP or OTP or LOL or DigiCert SHA or servers or certificates. I'm not trying to hack my phone, I just want to use it. Obviously you buy a Sony at your own peril. This is not the 80s where customers have to post a letter and pray for a reply. I'm going to broadcast this as far and wide as I can over social media so my friends won't have to deal with this. I hope that Sony will realise that putting a phone out there is a bit different to making a walkman. Adieu Sony

I've kept my Z3 as a backup phone and today it became necessary to use it again. I did a factory reset and would like to update to the latest firmware. When I go to "software update" it says "your device is up to date." Surely it's not up to date? Then I installed Xperia Companion. When I open the app it says "Xperia Companion could not verify the server certificate. If you experience any unexpected network errors while using the software, please ask your network administrator to allow Xperia Companion through your firewall or content filter. DigiCert SHA2 Secure Server CA" When I connect my Z3 to my pc it doesn't see the phone. The app is allowed in my firewall. Can anybody please help me to update my phone to the latest firmware.
