It is a pain in the butt. However, you have to first connect to the device, then monitor, then in the brackets there are numbers. ex: [8,14] The first number is for the left line, the second is for the top column. Then type disconnect, followed by what word is there where the two meet. Be sure the numbers are in green. Hope this helps.

The numbers tell you where to look for the password to unlock the cage. So when looking at the device's code. (I through the Monitor option, after connecting to it and scanning) You should see a lines of code and there should be a green or red brackets with numbers. ex: [0,12] These numbers will help you to find the password. The password's hidden in the memdump. You will need to figure out how the last used command maps to the last accessed memory by trying out the other commands. Then use the unlock command with a wrong code to make it the last command, then read the last accessed memory to figure out where the password is. So in this case the code to unlock is "unlock block" It's tricky and very annoying.
