[Solved] Cant unlock my vox :(

[stevenstrike]

Hi everybody...

So i've read these tutorials :
HowtoUnlockS710 (http://wiki.xda-developers.com/index.php?pagename=vox_uspl)

Flashing Rom (http://wiki.xda-developers.com/index.php?pagename=vox_flashing)

and nothing... i got all the time the same errors :

1st at : uspl_116_jockyw.bat

can't erase itsutils.dll bla bla bla
and then
Flash.exe(or RUU.exe) : 3% Image file corrupted

i just want to make wm 6.5

So i think that SDA_Unlock dont really work !

i've tried everything :
reboot'n'remove SD Card
dont reboot

i got all the time the same errors..

So can you help me, to break this ****ing lock ?

Thanks for listen :)

PS : I'm on Windows 7 x64 Edit : tried both Windows XP 32bit, same errors...

Edit2 : Ok, ive manually launched haret.exe, and my SDA says : blabla Application Unsigned blabla so you cant launch
I dont understand ! SDA_appunlocker tells me, SDA unlock... but he does nothing.. Help me please !
