he can download gdfs from topsony and it will work.IT'S NOT GOING TO BE BRICKED...I flashed with DCU-60 and setool2lite a different gdfs on a k750 and it worked...i also flashed a different gdfs at my w810 and it worked,but the phone was locked...i used the unlocking patch and now the phone works PERFECTLY WITH ANOTHER GDFS FROM ANOTHER PHONE...

of course i cannot guarantee anything,do it at your own risk...
