Sounds like a hardware issue that needs professional attention.

You tried to "heat" what exactly? And how did you go about this?

Most likely you fried your board in your iPhone and now it's malfunctioning. This would be a good indication that you should probably not do maintenance on your iPhones anymore, especially when they're still under warranty.
