When you’re doing this step in reverse to attach the new battery, be sure that you fold over the connector strip like it is in this image so that you’re not trying to snap in the new connector upside-down.
It sounds like you may have done something similar to what I did, which is tried to reattach the connector upside down. That’ll give you the flashing battery symbol but you can’t turn your phone on. The connector is supposed to fold over (look at the old battery, or the Step 6 image) and when it does it fits in snugly with the pins and you’re good to go.
