Hi @Sidien8081, let me see if I can help out here!
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
Could you possibly elaborate your question a bit? For example, Are you not able to download a system update to your phone or are you not able to install an update? Are you trying to update your phone using the phone settings or are you using Xperia Companion?
Please do elaborate as much as you can and I will do my best to assist you!
