Try it with a fully charged battery. I just tried it again and it's not working for me either. There are only 2 things different from before. The battery was fully charged, and the phone was deactivated as I had switched to a backup phone. I don't see how whether the phone was active would make a difference, which just leaves the battery. I've seen other restore processes for other phones that require the battery to be fully charged. Could be the same here. The reset might not function unless the battery is fully charged to prevent the risk of the battery dying while it is resetting. I am charging mine now, will try it again in the morning.
I know I should've left well enough alone, but I was getting some errors again and wasn't getting any help with recovering apks to fix it. :/ Anyway, I felt relatively certain I would be able to get it to work again...just gotta figure out what the missing piece of the puzzle is. Hope it's the battery. If not, I'll switch to the backup phone again and try it. *fingers crossed*
