Xperia mini 17i update Android 2.3 to 4.0 I try update Android from 2.3 to 4, using tool Sony PC Companion 2.1.
Tool want terminate processes wininit.exe and java.exe.
I can't terminate this processes using Far manager and Task manager.
When I accept termination of processes by Sony PC Companion 2.1, my computer is restrted.
Any ideas?
You can't terminate wininit.  If their installer is trying to do so then it's broken, or trying to install a rootkit by replacing system files in use by wininit.  Normally you should have an option to ignore the warning and it will simply need a reboot after the install (though given that it's warning about a system process, I wouldn't trust it as far as I could throw it).  Did you get the installer from Sony's official site?
