@michaelbro89241 There are some SOP to follow with any water immersed device.
Let it be known that Rice does not work. It does absolutely nothing to help you with this repair. All it does is waste time and waste food. Check here https://www.ifixit.com/News/30047/rice-i... for more on this.
For now, you must stop continuing to try to charge, sync or otherwise use your iPod. This potentially can make a bad situation worse as it may further damage your device.
The very first step I would take is to disassemble your iPod. Use these guides iPod Touch 7th Generation to help you disassemble your iPod. Take a careful and close look at all components and connectors. Truly assess for any damage. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as the cable ends. You will have to remove all the EMI shields. If you do not remove the shields, you are not cleaning the board. Once you got any gross contamination cleaned, use 90%+ isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for an Apple iPhone 3G but it is still pertinent to your iPod as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. The importance here is the cleaning. It would of course be best to get it professionally cleaned with an ultrasonic cleaner. Do not forget to replace the battery. This is a must and not an option. It will fail if you do not take care of it now.
After that, reassemble your iPod and re-evaluate. For as long as you have not cleaned your board and replaced the battery, everything is just a guess. Keep in mind that water damage is the hardest to troubleshoot and to repair. It does not matter if is was exposed for 2 seconds or 2 hours, what matters is where the water (particulates) did the damage.
If you find anything that may have gotten damaged or if there is anything you want to point out for further explanations etc. take soem good pictures of your board and post those with your Question. That way we can see what you see. 在已经存在的问题里加入图片
