So I currently completed companions and college of winterhold quests but I'm unable to continue the thief guild i even try using the console commands and for dark brotherhood i'm not getting the message from the courier.
For thief guild I'm stuck at:
the quest where brynolaif introduces me to the guild:

• get a completion for previous quest
  
• no quest showed up though...
  
• followed him
  
• get murdered in cistern
  
• try console commands didn't work

HELP PLZ
