If you are locking for samung z107 unlock sollution, why don't you just try with same program that you have when unlocking a z105?
simple use. com connector and short tx and rx pin 2-3 on the (com)
use samsung original usb cable PCB157ULE
1. plug in phone install usb drivers
2. open QIWS_V1.16(Service)_041011.exe
3. plug in com adapter (tx and rx shorted)
4. check if program finds samung modem. (if not found, go back to 1)
5. press ok
6. press unlock, (if you get usb error try to go to 4 and change the usb comport manualy to something else)
7. if phone unlocked insert a gsm card (if you have problem with network just change it manualy to gsm instead of automatic)
links for program and cable information can be found here...
