Ipod Touch Problems (ios 6.1.6)

Question

This is will be kind of long so please bare with me and read if you think you can help. I could really use it
This started after the recent update from Itunes. So after updating my Itunes i tried to add music onto my iPod like i normally do. it came up and said it couldn't recognize my iPod. so i unplugged it and plugged it in again. when that happened everything seemed to work just find until i tried to add a song to my iPod. My Itunes froze on me all the while deleting every single song from my iPod. now what makes it weird is through iTunes it shows all my songs on my iPod but when actually going through my iPod there was "No Content" . So i restarted my Itunes and again tried to add more songs. Only difference now was i  dragged the songs over. But nothing happened. Out of last stitch effort,i managed to add all my songs back and everything was fine. until the next time it came for me to add songs to my iPod.
My iTunes would freeze horribly the minute i would try to add a song. Thankfully this time it didn't delete anything off of my iPod. i would have to Ctrl+ALT+Dlt & end the process cause just trying to close it out from the task manager would just freeze it even more. So after that i decided that i would revert back to an older version of Itunes hoping that it would fix everything. So uninstalling the newer version of Itunes I installed a previous version that caused me no problems whatsoever. But to my dismay They same thing kept happening even when using the older versions of Itunes. It would freeze the minute i would try and add a song. So i stopped adding songs on my iPod for a couple of weeks. and even went through a MASSIVE cleaning on my computer just in case it could have possibly been a Windows problem.
So this last go round i decided after a couple weeks i would try and add 3 songs to my iPod. The minute that happened my Itunes froze and deleted every single song off my iPod. So to cut my losses i factory reset my iPod in hopes that would fix the problems if it was in fact my iPod and not the Itunes Software. That's when the strange things started happening. I slowly started adding songs back and it was working as i was doing 5-6songs at a time in hopes of not freezing it by adding to many songs at once. I got to the "S"'s and it immediately froze my computer and deleted all my songs off my iPod again. So starting over,i decided to add 2-3 songs this time and once again when i got to the "S"'s my iPod froze and deleted all my songs off my iPod. This happened about 8-9 times at that point i had enough.
I got into contact with Apple support tech and through the phone we went through the steps of  uninstalling each component. that's when another problem occurred. for some reason i had 2 Apple Mobile Device supports. one that was from the recent update this year. and one that said it was from 11/7/2011. were that came from i dont know. i managed to safely uninstall the most recent AMD. but couldn't do the same for the older version. it kept telling me that it couldn't find the .MSI file
That's when i scoured all over the apple forums to find a remedy to this situation. from unzipping the Itunes setup,to trying to repair it. to using revo setup to get rid of this AMD that wouldn't go away. so i stumbled on a windows program called fix it. which it showed me 2 AMD even though it was only that one device from 2011 since i successfully deleted that file. fixit managed to remove both files. so i figured i was in the clear. i re-downloaded Itunes again, but the problem is STILL there.  My Questions are
Is there a solution that hasn't been thought of?
Could it just be my iPod is the problem and it's time for a new one?
would a possible 3rd party iPod manager work instead?
is there a possibility to downgrade to a previous ios for my iPod?
I really dont know what else to do. Ive tried every remedy Ive seen on this forum and from what the tech's told me and even they dont have a clue what to do. unfortunately I'm over my warranty so sending it in for a new one is not an option anymore. i just want to make sure Ive done all i can before giving up and tossing this thing in the trash.

Answer 1

I would try:
- Another cable
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- on another computer to help deptermine if yo have an iPod or computer problem
- If a computer problem then:
- You can either backup your data and do a fresh install of Windows
- Restore your Windows to an earlier point i in before the problem started
- Wait for an update to iTunes
Yes yo can use a program like iFunBox to manually copy music and some other things to and from the iPod and computer.
Downgrading the iOS is not supported by Apple
