Update with PC Companion

[Tamir]

Hello,

I have Sony xperia z tablet and i want to update my android version.
Right now the version is 4.1.2 and I saw that the newest version is 4.4.1.
When i enter to the update center on my tablet it written "Only with PC".

So, I have downloaded PC Companion Sony and installed it.

For the first time i wanted to update my tablet it write me that the tablem must be with 50% charged, so I charged it.

From this period it always write me "Server not accessible" no matter what I am doing.

This message appears for a while and I can't update my tablet.

I have windows 8 and I have tried to install it with compability mode to XP or windows 7.

* I can't install the update by wifi because this update must be installed with the PC.

Hope you will answer me soon to solve this problem.

thank you and have a nice day!

It's probably a temporary issue, perhaps maintenance of servers
