After finish the SETUP
Go Back to Software download area for K750 download the Flash Device driver at (Update USB Driver)
When your computer pop up found new hardware USB Flash device use the driver u just downloaded
If doesn’t pop up new hardware, go to control panel -> system -> device manager (Click View device by connection
& show hidden devices) try to hold down the “C” keys of your k750i and you will see the USB Flash Device
pop up quickly grab it and update driver
Afterwards your should be able to upgrade your SE K750i thru SE website
Else,
If can’t find your USB cable, this mayb because the driver for both USB K750i & USB Flash Device is comflicted, try to uninstall all your SE program and files including the update and delete the Sony Ericsson Whole folder. Please make sure u uninstall all the program first. U can do it at control panel -> add/remove program there. After that you go to my computer looking for sony ericsson folder n delete the folder as well
Reinstall all the program and try again repeat the step
Wish u success..
Update will only start when the USB Flash Device is correctly installed

This sites is really suck(s), never try to update your firmware here, unless u really know u will pay for it.. Althought the web doesn’t mention it this site is really a trap.. Dun fall into the trap.
Warning : Once you use their client to FLASH YOUR K750i your phone will appear “CONFIGURATION ERROR … AND ASK U TO FIND YOUR SERVICE PROVIDER OR SERVICE CENTRE…etc.) This is because you don’t done the final step after you flash your Phone… You need to pay EUR 10 for Username and Passward in order to get the FINALIZATION code in order to let your k750i alive…. U R forced to pay bcos there is no other way to restore back your phone, unless u use SEtools3 oso need to pay for it. GO To SE update also useless, recovery mode oso can’t help. Onli way is to pay $
