BACKUP ORIGINAL EXE.
use XVI32 free hex editor. search down for (old) hex bytes till found them in  matching offset. select one byte before the replaceble (old) value. open replace box. in replace-with window write (new) value. click [OK]. u can see the new the bytes. save the file. make a new exe shortcut to desktop. launch the exe or shortcut. press ~ Tilde key and write commands.

In build 1.2.5427.16 (latest origin patch, as of this post), you can patch the bytes in MassEffect3.exe at file offset 0x1518AEC from (old) A0 7B 6B to (new) 60 31 D6 to enable the console.
FOR CRACKED RELOADED UPDATE 1.2.5427.16 
OFFSET 0x15164E2 ;from A0 7B 6B to 60 31 D6

Note that there will be no output from your commands, but they will work (if properly entered).
RELOADED console works like charm, though. :D (U dont say)
For example, from the main menu, try the command: open BioP_MPNov.

Obviously, you should not play multiplayer with this edit.
