@uamoti I gave up on it for a while and when I came back and saw your post it gave me hope. I was having some trouble executing what you did, but I couldn't continue because my phone simply died. It won't charge, it won't turn on. Nothing. What a bummer.
edit: After many, many attempts to turn it on it finally came back to life. Now I go back to trying to flash TWRP. So far I've been unsuccessful.
