Hi Ricci,
Have you checked out the inside by opening it? Try checking the wireless charging cable and see if you forgot to plug it back in. If that isn't the case, it could be three things. The first thing is that the coil could be damaged. Unplug the battery then gently remove the coil and inspect for damage. If there is damage, you can buy a wireless coil for cheap. If there is no damage, it could be a possible battery problem. Try unplugging the battery cable and plug it back in. If that doesn't work, it could be a possible board issue. If the old battery was removed with some power left in it, there is a chance that there could be a chance that the battery shorted the wireless coil or parts around the coil that makes it possible to charge. I hope this finds you well.
With regards,
-Duc
