iPod won't sync, music app crash

Hi,

So i need some help with my iPod and iTunes.

Problem started when i updated my iPod to that cursed ios 10. Really hated it, so downgraded back to ios 9.

Then my music app just started crashing. It would load, i'd click on a number/playlist and BAM it crashed and sent me right back to my home menu. So then i thought 'ok lets try and sync that ******* with itunes, maybe that'd solve it.' But nope. it doesnt even recognize it on itunes now. (previously it did, and my pc DOES recognize it).

So i tried updating to latest iTunes 12. And still nothing. I was thinking about a reset on my ipod but i can't get a back-up. (since itunes doesnt recognize it and latest back-up was on the ios 10, and i heard ios 10 back-up doesnt work on ios 9 after you downgrade it) And if i want to do a reset, i really want a fudging back-up because there are 4222 numbers on there which i dont have on my pc.

Also, **** no i'm going back to ios 10. **** that update.

So, i've already tried these things:

- Soft reset on my iPod

- Re-installing iTunes

- Tried backing up with CopyTrans (which also didn't recognize my ipod)

- Turning everything on and off multiple times

Please help me i'm really close to just throwing everything out of the window.
