For example....I load desktop manager and crackmem and I select ICQ to be remove and hit Execute Selection, it says "Action Complete" but when I check my blackberry ICQ is still on there. What I am doing wrong?
crackmem only removes the options from the OS installation files. you will need to do a wipe of your phone and then a fresh install to benefit from crackmem.
You do not need to wipe the phone. Download and install to your pc the same os you have on the phone. Start crackmem and remove what you like from the os. Then connect the BB and open DM. It will see that changes have been made and remove the the modules.
