Sometimes I can get the phone to boot and work normally but most of the time it just gets stuck at the apple logo. Its so weird because the home button does respond with the vibration. The phone gets hot if I dont hard boot it until its off. Ive tried doing a restore, didnt help. Maybe internal ic damage? Which one?

You guessed right, internal ic damage.

I got a iPhone 7…customer wet the device and both ear speaker and mic didnt work….so i changed the audio IC..now the home button is not working! is there any lines through audio ic that go through home button?
