Hi! My iPhone won't turn on n charge. I can connect to the iPhone in DFU mode and iTunes has detected an iPhone in recovery mode. Popup the message You must restore this iPhone before it can be used with iTunes.

I go to other shop they think may be PM ic isn't working they change the IC but iPhone still won't turn on.

Now the problem is after change PM ic i can't connect to the iPhone in DFU mode.

Is Possible after change the original PM ic to other ic can't connect to DFU mode or recovery mode???

Thanks

Like with all electronic devices, you should have brought the phone to a certified Apple repair service.
From here we can't tell what's wrong with your phone.

Additionally, what is a PM and IC?

Thanks for reply. if phone is dead then people suggest to change the PM ic.

For 99.9% of users that equates to contacting Apple Support or taking their device into an authorized repair shop. I'm pretty darn good with my Apple devices but, with the exception of my MacBook Pro, you'll never catch me prying them open and replacing broken chips.
