Guess its due to the fact I bought it second hand.

Anyway, this is what I did and you should do in five steps!

1: First of all, we need to get into the device. Lets ssh into it!
Install the ssh's client and server. Now ssh into it with a ssh client for your OS. The user to use is: root

2: Now you should be inside your N900 device, once there we want to get the so called DES hash of the password.

Code:

echo root:$(grep -A 13 lock_code /dev/mtd1|tail -1):

Now you get a output something like this:
root:63NCRYqE75Us0:

3: Copy the output and put it in a file on your computer, named: old_maemo_lock_code

4: Make a search for John the ripper and install it.

5: Open up a terminal and write:

Code:

john -format:DES -i:digits /path/to/old_maemo_lock_code

There, now just wait 5-10 minutes
Thanks to however wrote the post with grep part above!
