I changed my battery and my phone booted on when I plugged it in. Problem is that none of the sleep, volume or ringer work.. How can I Fix this??
you probably scraped the power/vol flex while removing the battery. The power/vol flex is a replaceable part, but a pain in the butt–order one and install. you can confirm that bad flex is actually the problem by first overlaying the new flex without installing it and plug it in. Then test before installing it.
