Nokia BB5 (3G) 6630, 6680 6681, N70 and N90 Unlocking




I provide this service with no guarantees, every effort has been made to ensure that the information is correct but you perform this entirely at your own risk, I accept no responsibility for any loss direct or otherwise.

I would add that this process is not as straight forward as with the older nokias.

 
 

This works on 6630, 6680 6681, N70 and N90

Download the archive:
HERE
And extract it to the root of the C:\ drive. The archive itself contains the folder bb5_unlock that it must work in inorder to run.

copy the files in this archive to c:\bb5_unlocker so the directory structure looks like:
C:\bb5_unlocker\backup
C:\bb5_unlocker\logs
C:\bb5_unlocker\psw
C:\bb5_unlocker\install.bat
C:\bb5_unlocker\list.txt
C:\bb5_unlocker\bb5logunlock.txt
C:\bb5_unlocker\BB5logunlocker.exe
C:\bb5_unlocker\BB5_calc.exe
C:\bb5_unlocker\logs\bb5_unlocker.cfg
 

Connection
 

For this program you need Fbus cable like DK5, CA43 or similar conected to one of the ports from COM1 to COM9. This must be the correct cable for the phone, not just one that fits.

Edit the File C:\bb5_unlocker\logs\bb5_unlocker.cfg using notepad or similar to the correct port for your FBUS cable. By defalut it reads COM2: You can find your correct port my looking in your device manager. (right click my computer - properties - hardware - device manager - ports)
 

Using
 

the programme BB5logunlocker.exe can only be launched if the .cfg file has been edited properly.

Connect the phone with the SIM card removed

launch BB5logunlocker.exe

Unlocking

Click 'read phone', this will display some info regarding the phone including the lock status.

Click 'Back Up' do not modify this file.

Click 'Make Log' this will add a file to the logs folder for your phone.

Launch BB5_calc.exe this can use the log file to calculate the unlock code for your phone. This will be saved to th folder PSW.

Click SP unlock - Unlocking done.
 

Unlock Codes From Your Network
 

If you got an anlock code from your network but messed up entering it via the key pad then it can be done from here. you will simply create the file in the PSW folder yourself.

create a file in the psw folder called xxxxxxxxxxxxxxx_BB5.psw where xxxxxxxxxxxxxxx is your IMEI number.

The contents of that file should be:
#pw+yyyyyyyyyyyyyyy+c#
where yyyyyyyyyyyyyy is the unlock code and c is the unlock level number (1-7) then use the SP Unlock feature as before.
