It's a hard brick,needs motherboard replacement.
If you even get no light on the screen it's for sure, did you try to flash a rom ? If so,was it a rom for your model ?
That's the way to hardbrick your phone,i did it once myself and i think it's the only way to a hardbrick

What makes You think he needs to replace motherboard?
Just because it doesn't work now, it doesn't mean it won't work again.
OP - do you know anything about this phone? Where did You get it from?
My old HTC had same problem after beer bath
Disassemble Your phone and look for water damages.

[Q] please help me to save my hd2

my phone hang with wite htc logo.i tride to hard reset,i faild.i could not put the device in boot loader mode.please help me. thank you
additional details please?
like what did you do before it starts to hang at boot screan, what hacks do you have installed e.e. magldr, hspl, sspl ??
those would really help
by the way you sure you cannot boot into bootloader the tri-colour screen?
To put the device into bootloader mode,
hold the volume down button and press the reset button, or else, switch off the phone (by removing battery), hold the volume down button while you switch it on. This must take you to the tricolor bootloader.
The stuck might have caused due to improper flash or something which doesn't match, a bad radio or so.
Its important for you to get into the bootloader, to flash either from Sync or SD Card.
All the best.

So, you said you cant go into bootloader mode.
How about retry it but following this way.
-Remove your battery and wait for minutes (maybe 10 minutes)
-Reinsert the battery. Dont turn it on.
-Charge your phone and check whether the phone is charging (you should check the led indicator. if it is full, the color should be green).
-After that, press volume down button and power on button at the same time (dont miss it).
-If you still cant go into bootloader mode, I would suggest you to bring it to Repair center.
Goodluck
I see, its not going into the bootloader, so can the problem be with the volume buttons? Are you sure they are functional?
Is your phone turning on, getting to the HTC logo and then turning off again by itself? This was happening to me just tonight. Just try putting the battery in the freezer for 20 minutes or so. That did the trick for me.
hello
thanks guys,i tried every thingas you said.no use.so i took the device to service center.they told me that,the only thing is to recover the phone is replacing the mother board.it is costing nearly 200 usd.

Which one was it a bad connection with your processor from overheating or machanical shock, or was it a bad NAND chip? These are the two things I was thinking as I have been following this thread.

i think it is because bad nand chip.
Was the phone functional before? What OS you had?
I've seen this on about 3-4 of the over 75 HD2's I've JTAG'ed. It's a faulty NAND chip that overheats causing this problem. Unfortunately, there is no logical fix for this.

For me it seems that you have battery problem... open the back cover, and check battery serial number... if it begins with BD, you shall call Samsung Customer Service requesting replacement.
By the way: does the phone behave in same manner while connected to charger?

Hmm... most likely hardware fault. Because of the similar in each case time, I'd say that you have faulty element, which heats up, and then disconnects/causes disconnection of power.
Sad to say, but it is likely that you'll have to go to service.

[Q] S4 wont turn on

Well mine S4 turned of last night it freezed and it turned off. I'm on Broodroms Pre Final 4.4.4. After that it turned on and shows only the S4 splash screen and then it turns off again and it won't turn on. After i pulled out the battery and placed it back then it boots but then again it shows only the S4 splash screen and then it turns off again. I've read some things on the internet that it maybe can be a dead battery that is causing this problem. Or maybe it is an another problem maybe that you XDA members can help me it would be great :fingers-crossed:

If u can boot to recovery, flash your stock official rom. Should be fixed after that.
Or you can also flash your official rom in Odin.

Is your phone charged? The very basic question.
Put it on charging for a while try getting in the download mode then.
If still no succes..then there is a way too...

That happened to me once and reason was because the phone was not charging (even if USB has power supplied).
To solve this, I first removed it from the samsung charger and charged it using a laptop or computer for approximately 10 minutes.
That will get it charging

try booting into download mode if at all possible and try flashing a stock ROM via odin!!
hit Thanks if it helped!!
I've tried to connect it to my laptop but it won't charge unfortunately. I'm also not possible to get it in to download mode it shutdown after a few seconds. And it wil only turn on If I remove the battery and replace it the phone will vibrate, show the Galaxy S4 splash screen for a second or two, then it turns off again. Searching on the internet people say that it's a faulty battery so i could try that method and if that is not working i think it's something with the mainbord (i hope not)

Change the battery AND/OR
Try a USB JIG then. The final thing that can be done. Heard it works with i9500 too.
Buy yourself a USB JIG from ebay or something and try getting in the download mode. It costs less than INR200.

Clean the terminal of the battery and the connectors of the phone..see if this works?
Well something like this hapoened to my note 2 because of moisture in the charging jack..the charging jack was okay but the battery wentt kaputt.

Well i've received my new battery and tried it but the same result so i don't know what could be the next problem maybe you people have got some other ideas what the problem could be? (hope so)
I've made a video of the problem. Don't mind the screen it's broken for half a year so far and the phone was still functional. Last sunday this problem appeared and i don't know what to do so far...

[URGENT]Samsung Galaxy S4 GT-I9505 Stuck in bootloop

Hey XDA members
I need urgent help to help me restore access to my phone, as you can see in the title my device is stuck on the Galaxy S4 Screen, wont go further (apart from a few lucky times hardly ever and will restart anyway).
I have no idea how this happened, my phone is fully stock, not custom roms or root or anything. i was just using my phone normally and all of a sudden it turned off and it just happened from there on, its been happening all day and it has really p****d me off because i am unable to keep up with work now and my phone pays a vital part in my life.
It's not water damaged as far as i know and i cant even factory reset it because it freezes in the process of going into system recovery mode and restarts, same goes for download mode. i really dont know what to do the PC Doesn't recognize it anymore either and its not got warranty.
The only possible thing i can think that has gone wrong is i was charging my phone in the USA Whilst i was there during the summer. but that was about 6 weeks ago and it just happens so randomly so i doubt it could be that..
Has anyone has a similar problem and can give me any solutions or advice i would greatly appreciate it.
- Kind Regards.

Had the same with 4.4.2. Do a factory reset, should work. Although all of your data is gone that way.
I suspect you have a hardware problem. Take it to your nearest repair centre.

The simple answer is no, I don't.
Considered the info provided I think you're out of options, unfortunately. Sorry mate, repair centre is my humblest opinion.
