Is My HD2 Really Bricked?

On Saturday night i was txting playing beer pong having a good time.
When all of a sudden a black screen came out saying something about how it was goin to restart and reset or something like that and that all my personal info would be gone.
So i did it and once it restarted it just stayed stuck on the boot up screen.
Not thinking twice about it as i was having fun i just put it in my pocket thinking maybe its gonna take a lil longer but then i realized after awhile it was still on that same screen.
I took out the batter turned it on again same thing happened.
I gave up and decided i'd just deal with it the next morning.
Next morning comes its now like around 1-ish crazy party haha
Point is phone is dead i charge it for 30 min? i try turning on and nothing.
So then i boot up pushing both buttons figured i would do a hard reset.
Still nothing!
My friend decides to take me home so i take this time to charge my phone a lil more with his car charger and at first it was charging then out of no where it doesn't charge?
No light?
No boot up?
Nothing?
I take the battery out and back in then plug it into the charger and the light doesn't turn on but my phone just starts vibrating uncontrollably...
This freaks me out so i take the battery out and again same thing.
I took the battery out for a couple minutes then put it back in and it started charging again.
yay!
Oh btw the whole time this happened i was able to get into bootloader mode so i figured it cant be bricked and i can fix it just got to charge it.
I got home battery wasn't that charged but i plugd it in to my computer in bootloader mode hoping it would charge for a bit then i downloaded a new rom and i read it was a good idea to use task29.
Sounded like a great idea to fix my phone.
I got the Repack by ShaDrac and flashed it on my phone.
One strange thing i did notice was that usually when i flash it i see HTC then a progress bar.
This time it was just blank all black but with the progress bar i saw it go all the way to 99% and 100% on my computer it even said successful flash.
But after that it just stayed off?
No reboot ?
NOTHING!
wont charge
wont turn on
no bootloader mode
completely bricked.
im sure the battery is just dead since it wasn't that charged to begin with but i have no way of charging it!
I did a lot of googleing and found no answers i refuse to believe its bricked!
it cant be rite??
If anyone could please help me i would really appreciate it.
Ive only had my HD2 for about a week =[
Oh and it's a T-Mobile US version unlocked.

If you have only had it for a week then the best thing is to just take it back to wherever you bought it and ask for a direct replacement as it should still be within the time frame for that.
Sounds like you have done everything possible to bring it back, taking the battery out, hard reset. If it wont turn on, wont go into the bootloader and you cant get an activesync connection then theres not really much more you can do.
Mark.

yea i agree, dont waste time fiddling and trying to bring it back, get round the shop today.

Unfortunately thats not an option as i got it from someone else and then unlocked it since im on at&t. At most i would have to call htc and hope the manufactureres warranty can do something but i highly doubt it.
cant believe this is the end of my HD2

You might try taking the battery out and leaving it out for at least 24 hours. Sometimes that will reset a few things and bring the screen back on but im not guarenteeing anything. Yo uhave nothing to lose at this stage though. You could also try connecting it to your pc via activesync and see if it connects. Even if the screen isnt coming on you might still get a connection which you could use to flash a new rom.
Even getting a replacement battery off ebay very cheaply might sort it out as I have heard of batterys going funny before.
Just a few sugestions.
Mark.

all the phones should (I think) be manufacturer warrantied for the first year, so I bet htc will fix it, though you might have to pay shipping.
dig out your regions htc repair center and get in touch. so long as they can't see the hspl it should be free.(

I dont have HD2 (<--nexus one), but one thing i have noticed with all HTC phones that I've had something similar happen is when i have tired to reboot the phone by turning it off and then trying to turn back on it wont. I would take the battery out and still it will not. I would do the same with the sd card and same but what fixes it is taking the SIM out press the power button few times with no battery and then putting everything back on and it turns on. It happens in a while. Maybe not the same problem but i guess its worth a try if you haven't yet. One more thing I would try is to take the battery out, the sd card and the SIM card out and then plug your phone into the charger and wait a few mins to see if the led or screen would come on. Try the same thing by plugging it to your computer. If computer does make sound and it does detect your phone then it might just a screen related issue which might be the case since you already flash it with a different rom and nothing came on. I know you probably have tried this but you didnt say in your post but have you tried this?
1. With the device turned off, press and hold the VOLUME UP and VOLUME DOWN buttons, then briefly press the POWER button.
2. Continue pressing the VOLUME UP and VOLUME DOWN buttons until you see this message on the screen:
“This operation will delete all your personal data, and reset all settings to the manufacturer default settings. Press VolUp to restore manufacturer defaults, or press other keys to cancel.”
3. Release the VOLUME UP and VOLUME DOWN buttons.
4. Press the VOLUME UP button to perform the hard reset, or press any other button to cancel the reset.
Good luck

I agree with mskip about the 24H thing if you let the internal/backup battery die it could solve a possible brick then by reflashing
also what deanesn said about the HD phones its also true (same prob with G1 and excalibur) sometimes out off nowhere it wont turn on or its just going to give you a black screen... wierd huh!?
important things I wanna know is
what rom where you using? what radio version? what were the last app or apps you installed on your HD2?
anyways from what I've read&done ever since I joined XDA this is the best thing to do in a situation like yours
This is when you get a black screen
1 if its stuck on the boot screen try to do another hard reset
2. if you cant or nothing happeneds try to see if you can acces the bootloader screen
3. if you cant, remove the batterie for like 24H or maybe more so the internal batterie dries out (if you do that make sure that you try to estimate around 50% to 70% before removing the actual batterie for reflashing)
4. then insert the batterie and try to acces the bootloader or hard reset by pressing the key combanations dont try to see if by a miracle chance it would fix the problem (trust me at this point it wont)
5. if it actually DOES bootup find and download THE STOCK ROM FROM TMOBILE
6. HARD reset if nothing then do it agn but before it has a chance to, try to boot up
7. quickly acces the bootloader wipe your phone (task 29 for hd2) and flash the STOCK ROM (not a custom rom. I read somewhere that its always better to go with an official tmo rom)
thats it Ive try many things on my ALMOST bricked situations this are the things Ive done MAYBE IT WONT WORK FOR YOU, one time I thought my excalibur was dead until I left my phone without a batterie for like a weak then later out of nowhere it boots up only on the first tmobile splash screen and I was able to fix it
LOL even tho those steps prob dont apply to you what you can do is call HTC and tell them you have a black screen on your htc DONT TRY AND ACT all smart by telling them you have a brick and you had a custom rom and all of that cause that prob voids your warranty with HTC, from what I've read this one guy told them that his girlfriend was texting and then the phone froze and the she remove the batterie and the screen went black. And he got a replacement
also another one that I read is a guy telling them he was doing an OFFICIAL ROM UPDATE and the phone never turned back on.
hope it helps

Mark:
Thanks, and this is actually my plan lol I used to flash my old motorola rizr all the time even had to testpoint it to bring it back from a complete BRICK! but the one thing i couldnt fix was water damage haha but after a week of having the battery out some how... miraculously it came back
Deanesn:
How is the nexus one? I was gonna get a nexus one or a hd2 but the screen size ended up being the tie breaker although ever since my g1, android has had my heart haha
Ive always hated windows mobile but the hd2 was perfect!
I also agree with what u said, i have seen those symptons before.
But yea thanks on the advice.. sadly... already tried it and nothing.. =/
Tuppaacc:
Thnx thats exactly what im trying to do.
My only problem is my battery is dead and i need to charge it!

Oh i just noticed i forgot to answer ur questions Tuppaacc.

Im not really sure what radio i was using but if i had to guess i would say 2.10 since i dont remember flashing anything else and i heard the best radio was the one the HD2 already came with.
As for the last app installed ummm.... iGo8? not sure either but in total all the apps installed where
My Phone

iGo8
Aim
Flashlight
Glympse
umm cant think of any other ones. I know i didnt install much just had flashed the rom the night before.
again sorry for skipping your question.

try
try taking sd card out and boot it work for me

Here is what you have to do after I made a mistake and "killed" my US version HD2, but it's back to service.
First of all, you have to be sure the battery has at least 50% left. If the unit is able to charge the battery, leave it charged for a couple of hours.
Second, unplug all the cables from the unit, take the battery and wait for a few seconds, then put the battery back in. Press and hold volume down button and press red (end/power) button once. If everything goes well, you should see a tri-color screen.
Third, plug in the phone and run ROM update again.
WARNING: flashing will erase your personal data.

the thing is the phone itself wont charge the battery.
I plug it into the wall and no lights turn on to indicate its charging.

You need to get a desktop charger so you can plug the battery in and make sure its fully charged. I dont think they are available from shops but you can buy them online (ebay) for around a fiver.
http://cgi.ebay.com/Desktop-Battery...&otn=8&po=LVI&ps=63&clkid=9087015918333818927
That one says for the T8585 but im pretty sure they both use exactly the same battery. You might want to check on that though.
Mark.

My goodness, that OP is a real doozie.
That's pretty wild man, although I don't have much input, other than the obvious suggestions that have already been provided for you... I will say that was a worthy read.

Yea thats pretty much my only option I will be buying that desktop charger real sooon and ill get back to the forum with my results.
Cant believe they are so cheap haha
Ive even seen one that comes with an extra OEM battery and charger for under 15 dollars!

Thnx for all the help and support. =]

U have a Bricked HD2 my friend

i bought the wall charger and it charged the battery but it still wouldnt turn on or go into bootloader mode or do anything!!
=[
..

any luck with un-bricking your HD2?

Seems like OP bought a damaged phone in the first place or something, or something "happened" on the night of the party. Beer got on it, perhaps?

[Q] Yet another "brick" story...

Note: THIS HAS NOTHING TO DO WITH A ROM UPDATE!!!
Okay... My HD2 has had Android on NAND since last year. No big problems with it, until last week, when it FROZE when I charged it (the screen was still on, but that was it...). I took out the battery and re-inserted it a number of times, and it all seemed OK...
...Until it happened again.
Only this time, it didn't turn on AT ALL. I'm no good at explaining things, so bear with me on this one:
You know how the phone has a very soft and short vibration, followed by a more intense, longer one when turning on the HD2? well, the phone only does the short and soft one, and that's about it... Nothing else...
Does anyone here know what's going on? Is there any way to fix this without returning it? If I do have to return it, is there any way I can retrieve the data on the internal memory? Will they be able to see the flashed ROM?
(Note: It's past its warranty.)

Have you tried to get into boot loader mode? Also who is your provider? Last but not least....You said it was charging and you had the screen on? I don't know about you or anyone else but when I charge my phone I make sure the screens off. It just gets hot while its charging with the screen on. If you have done this more than once it might be damaged from the heat.

mine only vibrates once when I turn it on, not sure what second one you're talking about.
hold the down arrow when you turn it on and see if you can get into the tri-color screen, you can flash WM6.5 or whatever from there.

Past its warranty?
I thought HTC gave 24 months of warranty worldwide?!

i thought that aswell

@jvillejoe:
I have tried to go into bootloader mode, yet nothing happens. My HD2 is from Telstra (I live down under in Australia). Lastly, the charge light doesn't come up if I plug it in while the screen's off, so I have to plug it in while it's on, and then I can lock it as I please. I think it's a NAND-related problem.
@orangekid:
There's an almost unfeelable, really quiet vibration about a second before the usual normal one. To hear it, just put the phone next to your ear (not necessarily the speaker) and turn it on. If that doesn't work, it might be because it only happens on a Telstra phone (I honestly have no idea). And no, it won't let me into the tri-colour screen.
@lukesan:
24 months? I always thought it was 12! Well if I do ship it in, will they be able to detect the flashed rom/illegal Android/everything else? How much jail time do I get if they do?
This isn't the first time it's happened. It's happened about 4 times before, even when it wasn't charging. It usually fixed itself when I took out and re-inserted the battery a couple of times. Are these freezes a result of an app going haywire? Does somebody know the cause!?

well are all the battery pins in place? did they not bend a bit or something?

Yea sounds more like your battery to me

No it couldn't be that... It slightly vibrates a few seconds after I re-insert the battery and then does nothing... but I did notice that the phone would make these small vibrations every once in a while if I leave the battery in, which has convinced me that the battery isn't the problem.

That really sounds like a dead HD2. Them vibrations usually happens when people flash a European HD2 radio on a US.
What happens when you plug it in to your PC? Can you hear a little sound to know that the phone is connected?
Sent from my HTC Vision using XDA App

I had a similar problem (minus the soft vibration). You should try a different charge battery. If that does not help to get in boot-loader screen, I hope your phone is still under warranty.

you wouldn't go to jail? i'm sure flashing your phone voids the warranty but idk if you'd go to prison

[Q] Black screen after replacing

Hi Guys,
After I "replaced" the screen,it was blank, yet booting and visible to computer,
I decided to recheck - and switched to the old screen. It didn't work either!
So now I have two sceens but non is functional
Any ideas?
Btw, i found this topic

Got the same problem right now, trying to solve it. Was about to post new topic but saw yours. Can you boot your device into bootloader? Mine seems to be able to do that and I see everything but once it shows the Google logo during normal boot or recovery, the screen goes dark and blank.
Very mysterious indeed, never seen this issue before...
Hoping someone can shed some light on this...

Can you remind me of how you did it?
Cause vol up+power\vol down+power won't work for me
What screen have you bought?
Cause I was super anxious about getting original Hydis, now chungwa they now sell everywhere
at first, I would think that I somehow messed uo the cable - but if you are saying, that you are able to boot
mystery!
I guess, we need some experienced service man here

Vol down + power. Though upon further reassembly, it seemed to get worse. Now my screen won't even light up or show anything. Try shining a flashlight on the LCD panel. Do you see anything? If you do, it's likely a bad data cable. In which case, you should find one on eBay.
deltatux

It isn't working at all(
But I can't be 100% sure, cause I've so many change cycles
Buying things on ebay means +1 month of waiting, so I'd prefer to know exactly, will the new cable heal me tablet
Anyway, have you decided, what happened to your screen?

For me since I shone a light and there is something showing underneath and I know that the panel should work since I did see a Google logo and fastboot did properly show up before I reassembled it again 2 times before it completely disappeared, It's likely the data cable, so I repurchased a data cable from eBay.
Have you tried shining a light on to the LCD panel to see if you see anything? If not, it's likely a faulty LCD panel.

so i made the changes and it did make a big difference. i shut the phone down 2 hours after to charge it,, and thats when a odd thing happened.
its dead.
no life at all. even when its connected to my pc. if i plug the charger in it just gets hot.....thats it.
can i assume its bricked for some odd reason??

what happens if you pull the battery, plug it back in and try and reboot into recovery/download mode?

i did that + charger,and lead.
no responce and all. if i plug in the charger the top half of the phone gets quite hot in the main board area.
im sure some people come on hear with problems with out telling the full storey ( dropping it down the toilet,or just dropping it) but i literally shut it down to charge it quicker.
im still scratching my head over this.
if all else fails i may look into buying one with a smashed screen on ebay and replace the main board as my phone is in great condition,....gutted.

it does sound like a hardware issue - can you take it back to a samsung service center?

If you tried another working battery, tried connecting to a computer and cant get into Download Mode.... I say your phone is dead and it sounds like a hardware fault. I have seen soft bricked and hard bricked phones, they still show some form of life like the led turning on, pixel salad, black screen (as you can see the screen light up), white screen, cant get into recovery but can get into Download mode and etc.
Sounds like its dead but I am sure its got nothing to do with what you did and its just a coincident that it died.

[HELP] Black screen with no USB detection ?

So, my device had been acting funny for a while, automatically shutting down, stuck on boot loop, fingerprint not being recognised, battery draining really quick.
But since they had been a minor inconvenience, I didn't look in to the problem. But today morning, while I was watching a vid on the Youtube app, the brightness of the phone suddenly decreased, and using the brightness slider had no effect. And then, after a while, the screen went black, with only the finger print sensor vibrating, if touched. When i connect it to the charger, the LED light does not flash. It is not even getting detected when I connect it to the PC via USB.
Any help please ? I think the warranty has run out.
P.S. - All these errors seem to be taking place after the an update. Though I don't remember which one. Also, running stock ROM, didn't flash anything.

Also, I remember just before it went dark, it had just started raining, maybe one drop fell on the screen. Is any way that's the cause of my problem ?
