Update preparation initialization stops

[peirseaj_gmail_]

Am trying to update my Xperia Z to the latest Android version.  After some minutes of Initialization, it stops and won't progress even after a long time.  I've tried rebooting the PC and starting again, unplugging and replugging the phone, but always the same.  Can someone tell me (a) what the problem is/might be;  (b) how I can get the update done!

disable your antivirus and / or firewall and try again.

you can try SUS as well

Dear Uliwooly,

Thanks! I tried your first advice (disable firewall etc), but it didn't help - initialization stopped at the same place, 2 or 3 times. 

However, I did then follow your second advice (using SUS), which worked fine;  problem solved.

The use of Companion therefore remains an issue for updating the phone.

Brgds,

Adrian
