Samsung S22 Ultra sub ribbon cable backwards

I replaced the screen on my Samsung S22 Ultra and it said emergency use only. I ordered a antenna kit off Amazon and in the meantime I tried to start the phone up and nothing. Plugged it into the charger and the charge symbol doesn't even show. Then i noticed the sub ribbon was on backwards. I mustve put it on backwards on of the 10 times plugging and unplugged it when trying to diagnosis the antenna. Thinking about plugging the old screen back into it to see if it's a screen issue. What else could it be? Did I fry something? Motherboard?
