@Michael-Xie48 I have something better - I have a working Onion2! Just like in this thread https://community.onion.io/topic/1159/omega2-almost-doa/2, somebody had done a really sloppy job of soldering the metal cap on my Onion2. Someone had spilled so much solder that the board was shipped out with a short! In the linked picture, you can see that the short is in the top corner, just above the SD card holder.
