First, peel off tough membrane on the back of the ribs by sliding a butter knife under the membrane and over a bone. Then, just lift and loosen the membrane until it tears. Grip the membrane and pull it off.
In a small bowl, mix together garlic powder, onion powder, paprika, salt, black pepper, cumin and chili powder. Sprinkle seasoning and rub it all over the ribs (on all the sides).
In a large measuring cup, pour beef broth and liquid smoke and stir well to combine.
Place the rack/trivet (it comes with the Instant Pot) in the bottom of a 6-quart. Pour in the beef broth mixture. Place the ribs inside the pot and upright on the trivet.
Put on the lid, lock it and check to see if the vent is at sealing. Then, select manual setting; adjust pressure to high, and set time for 25 minutes. Mine took about 15 minutes to reach pressure. After the 25 minutes is up, let it naturally release pressure for 5 minutes. Then, do a Quick Release, which means move the valve to venting to release the steam. When all the steam is gone, open the instant pot.
Set the oven to broil. Line a large baking sheet with parchment paper. Transfer the cooked ribs to the prepared baking sheet, then brush with barbecue sauce.
Place in the oven for about 2-3 minutes. Enjoy!
