Ok, so it sounds like you've actually done the cache wipe, but the phone is still in a boot loop? Is that correct? My apologies, but it's just hard for me to understand. What is your native language? It might be better for you to type in your native language, and then I can translate it using Google Translate.
Are you able to boot your phone to the home screen at all? If so, then plug the phone into your computer using a USB cable, then swipe down and tap on the USB connection notification. You should be able to select a different connection option besides "Charge Only."
