Ok this happened to my friend at boces try first installing the new screen then restarting the phone about 30 minutes later just turn off the phone then wait 30 minutes later then turn it back on if the problem still continues please reply back it doesnt always work for every device
Try opening it one more time but this time take out all the buttons (the plastic part) with out any electronic parts and clean them with water after that turn on your console and try to use your controller if the problem still progresses you might have a sticky circuit board in that case take a screen cleaner and clean the circuit board after that check the controller again by turning on the console and see if the problem is fixed if it continues to progress i recommend buying a new controller.
You have to turn off your iPod then turn it back on while holding the home button you should get an iTunes logo with the charging cable on your screen. Next plug it in to your computer. Next iTunes should automatically detect that your iPod is in recovery mode. It will next ask you to back-up your device. Back-up your device. Next press the recover button if the button doesn't say anything try repluging it back in after doing the process over again then press store then let it go thats it.
