Check the derailleur placement.
The chain should be roughly centered in the derailleur, so that no extra friction is caused, and that the chain is not unintentionally pushed off the sprocket.
If not in the correct position, reloosen the tightening bolt and redo step 13. This may take several tries.
Make sure the shifter is in the same position as the chain. For example, in these pictures the chain is in position 2, and so is the shifter (the gears are numbered smallest to biggest). Otherwise the bike will not be able to properly shift.
