30GB Apple iPod Classic 5th Gen Black (Model A1136) For Parts/ Not Working

I bought this on OfferUp. The headphone jack didn’t work and I wanted to try and fix it. Since I’m an amateur, I ripped the battery port off the logic board as you can see in the photos. The clickwheel and screen work well. The hard drive works, the battery is old but works. The headphone jack didn’t work or it’s something else wrong (I couldn’t get it to play audio from the jack)
