I bought my girlfriend a z104v for xmas, it was locked to voda but I thought "no probs", I'll have a quick hunt on the net. One day later and I had managed to track down the UMTS programme but all searching for how to use the f**kin thing had failed, I was about to give up when I read your post.
You cut the bull**** and give it to us in plain language, after two days of hunting the internet and failing to get the programme to work, your tutorial had the phone unlocked in five minutes flat.
Nice work man, keep it up.
BTW, if the above link is dead I hunted my copy down on the e-mule network, download emule plus, search for
"Samsung UMTS WinIMEI" and if the file is 3,307 bytes then it's kosher and you can go ahead.
