Be careful of want you want to do!!!
Yes is cool to upgrade your phone via SEUS, but make sure that the firmware is supported by XS++ or Far manager... in case that you intend to upload flash menus in the future.
Why??? I give you an example:
I had an W710i CID49, and upgrade it with SEUS... and now I have the same phone with CID52 :(
The problem is that CID52 is not supported by XS++ or other flashing program...
So I can't upload flash menu's anymore :(:(
Now I'm waiting for new versions on XS++ with support for CID52
