A lot of the GSM traders loved this as they had just made loads of bucks selling version 1 dongle's and now they began to sell these newer dongle's/software at an extra high price! This newer software calculated codes that today we call version 2 codes. These so called newer codes could still unlock all the old DCT4 handsets but could also unlock these awkward 35101i's and 7650's. The new software produced a different variation of unlock codes. The software itself only acted as a front end and retrieved the codes from the dongle itself.Īnd so came the release of some new unlock code software, again dongle protected. The actual program code that calculated the unlock codes was actually stored in a small micro chip within the dongle. If the dongle was not plugged into the LPT port of your computer the software would not run. The dongle for the original DCT4 unlock code calculators was a parallel port device. It can come in various forms, commonly either USB or parallel port. These codes worked great for many months, but I guess Nokia got a little unhappy with this situation and as a result more and more people were reporting that these codes were not working on the odd 76i's.Ī dongle is a small piece of hardware designed to protect software. The dongle's calculated only one type/variant of unlock codes (known today as version 1 codes). The dongle actually contained the program code which calculated the Nokia unlock codes and the software acted as a front end to display the codes.
