I've searched plenty of forums regarding Android phones that are "Bricked". But it seems to me that most of the instructions laid out by the "replyer" require the phone to be opened up using special combinations of buttons that would either lead to the Custom/Stock recovery mode or the Download mode which is basically a definition of a "Soft Bricked Phone". A phone wherein it would still turn on and simply has problems with how the OS/Kernel/whatever runs.
Problem: I toyed with my Samsung Galaxy S4 in such a way that it would deal with underclocking my phone. I know that underclocking is a risky thing to do. But I was lowering it to the point where My phone would still run stable... until one day it just suddenly gave out. My phone would still turn on but for about 2 seconds and it would turn itself off immediately. That means that even if i was fast enough to go into the download mode or to my Custom Recovery mode, it would still shut off completely as if I pulled my battery out of my phone.
I'm not really in an INSANE need of help to repair my phone, but a good "Fixing a Hard-Bricked Phone is impossible." or something would definitely help as it would give me a sense of peace around all the threads claiming that they can fix such said phones that are in the same working condition as a brick.
thank you for any help.
