Phone suddenly went dead

I was using my iPhone 6 as usual and it suddenly turned off. It has not turned on after that.

I tried holding the "Home button + Power button" for 30 seconds technique and nothing happened.

Tried connecting to itunes and it is not recognizing. Tried to move it to recovery mode by pressing power button for 3 seconds, then home button (along with power button) for 10 seconds. Then only power button for 5 seconds. No luck.

I left it on charger for a few hours. No luck.

The phone is about 2 years old and needless to say its out of warranty. I took it to a friend who has experience in opening the phones. He said it seems to be an issue with the motherboard and its now as good as a brick.

What should I be doing? Any advice please?

It could be one of several things...but would start with the easiest and most obvious first.

I would first make sure your charger and lightning cable are good, then move on to checking the charging port for clogged or obstructed debris in the port preventing it from making contact to charge...then to the battery to check it for 3.8 to 4.2 DC Voltage to make sure it is good and charged. Then on to the charging port to make sure it is indeed charging the battery. (Using a multi meter)

If you have been using a generic charger or auto charger...it could be the U2 (Tristar) IC Chip has went out and will need to have it repaired by a reputable / Experienced Micro-Soldering repair shop which you can google to find one close to you or search here in the Business section for one to have mail in service done.
