Basically U need a mbus cable that fits your nokia phone, there is now no need for the lpt (printer port) flasher cable unless you want to upgrade the software version of your phone. Why do you want to do this I here you ask, because it solves minor bugs and/or adds some minior features to your phone.

To unlock a 5110 and older nokia phones, bare in mind some are restricted to just one/two networks (eg nk402 nk702) so will not work with all networks even if they are unlocked use your cable along with nokia tool 35, once you start the program click "readme" and then "open all". For 5110's with a newer software version use follow the procedure for all other DCT 3 Nokia phones (33xx, 62xx, 71xx, 8xxx, 9xxx)

Use "eeprom tools" by B phreaks version 3.1 and click on the lock icon. Thats it!

The software should be available in the download section of this site... NFREE
