Nokia Unlock (BB5) for 6630 6681 6680 N70 N71 N90 N91

Hi all,

Nokia 6680

Nokia 6680

Having just upgraded to the iPhone, I then had the task of disposing of my old phone(s) – The problem is that the kids always want to steal my previous devices, but are on a different network to me.

One of the phones (a Nokia 6680) was SIM-Locked to Orange. This phone is of the type ‘BB5’, this means that the only way to unlock this till recently has been to take it to a shop. Well not any more!

This is the step by step guide to unlocking Nokia’s of the type: 6630, 6681, 6680, N70, N71, N90, N91

  • Get a DKU-5 (or equivalent F-Bus) cable. The normal USB cable that comes with the phone is not suitable, it must be an F-Bus cable.
  • Install Nokia PC Suite (any recent version)
  • Plug the cable into the phone and then into your USB port and let your phone get detected.
  • Close down any Nokia Applications that might start up.
  • Right-Click on My Computer, and then on ‘Manage’
  • Click on ‘Hardware Manager’ in the left-hand pane
  • Expand the ‘Ports’ section and check which port the Nokia phone is on – NOTE THIS DOWN!

Ok – Next stage is to get the software.

You need to get the BB5 Calculator from here: http://users.net.yu/~dejan – [Direct Download LINK]

  • Unzip the file to C:\bb5_unlocker
  • Edit the “bb5_unlocker.cfg” file and change the COM Port to the one you noted above
  • Double-click on install.bat
  • Click on “READ PHONE”
  • When it says ‘Done’, click on “MAKE LOG”
  • Copy the xxx.log file (e.g. 317617303633274_BB5.log) from the /logs subfolder into the /psw folder
  • Click on Exit
  • Double-Click on BB5_calc.exe – it should say “Done”
  • In the /psw subfolder, there will now be an xxx.psw file. Open this is in Notepad, and you will have all the unlock codes. You can either enter these manually, or :-
  • double-click on BB5logunlocker.exe
  • click on SP Unlock

Following these instructions, I managed to unlock two 6680’s in 2 mins flat!
