Note 4 Issue

Hello,
Currently I am on S7 but I do miss my Note 4 (ATT and factory unlocked by att after the contract got over).
After Marshmallow update it started lagging, shutting off etc.. all known problems. To fix it I downloaded wake lock app and it worked fine but drained battery a lot.
I tried to flash it through odin etc... (not a technical guy I am, followed instruction from one of the threads on this forum).. took all the files on SD Card and after that phone never turned on.

It does not charge, no LED lights when plugged in, none of the buttons are responsive. I have tried everything like new charger, usb cable, PC, new batteries etc...

1) Do you think It's hardware problem?

If No then,

2) Is it possible to fix it and how?
Please note: Phone does not turn on or recognized by PC. If it is just software problem then I am determined to fix it. I may need instruction for even very simple steps.

Thanks in advance!

Sounds just like my other 4 from Verizon that just died one day and wouldn't turn on again. I think it's possibly the motherboard in the phone that's faulty which is causing it not to boot anymore. If I find away to get it up and running again I will post here to tell you the process.

Might have to ship it out in order to get it fixed. But let's see what happens to mine first.

Okay here's my question, on the AT&T Note 4 if you have the little jumpers right above the battery in order to provide a sure-fire power then if you were to root the Note 4 and it decided to cut power from the battery could you power it back up like that in order to undo the wrong or over-the-air Flash that they do that ends up breaking the four?

I have a Samsung note 4 (AT&T) was giving to a friend by his work. He has left that workplace and they allowed him to keep the phone. But mobi control is still on the device. Can i remove mobi control by flashing a firmware? The model is sm-n910a. Abit lost on this one

I do have a video which won't upload on here for some reason. I'll upload it to YouTube and post the link soon.
