Sure, you could do this. Don't know if it will help any!

I'm not sure as I don't work with Samsung devices. Your replacement sounds like it is defective though. (Unless you mean the device is locking, which shouldn't be happening)

Hey mate!

Yes, you cannot skip these steps. Not because of the electronics, but rather the plastic!

Let me know if there are any other differences & I will update the guide as appropriate.

Hahahaha I'm really glad man! Thanks for the kind words :)

Hey mate!

Almost certainly you need a new digitiser.

Hey mate! Glad to hear you had a success with the replacement :) Good for you all!

And yes, the screen is meant to get really hot (more hot than is comfortable to the touch) but don't worry if you did it another way :)

Hey mate, unresponsive to touch is a sure sign that the digitiser is shot. Getting a new one will almost certainly resolve this issue.
