SIM/Network Unlock Tool for Galaxy S and Galaxy S II (works only on older versions)


Most of us experienced issues with locked devices on specific networks, which is a real pain in the *** , because usually requires some experience using hex editors, or even paying your carrier or a third-party to unlock your SIM.

A senior member on XDA forums by its nickname Grooby has put together a nifty Windows application (tool) that will ease the otherwise difficult method created by XDA recognized developer Odia for people who are having trouble to manually unlock a device.

Network/Sim Unlock Code Generator works ONLY for older models of the Galaxy S II I9100, as this method does not work with hardware version 1.4 or above. The older version of the tool will also work for users carrying a Galaxy S I9000.
