Hello all,
So i found one guy who sells HTC hd2, but it has a strange issue, with android installed in it, it sometimes freezes, while ending the call, or playing angry birds after a while. When he installed the WM back, sometimes it restarts, after a while too, so what could the problem in the worst case for example ? He says the radio version is official. He suggested that it could be the overheating cpu, but i don't think so, so what do you think guys? The phone has never been took apart, got wet or something.
He said that he done hard reset too, but it doesn't work.
My first thought would also be an overheating CPU, but you'd be able to physically feel that if it was happening so that's probably not the case. Bad blocks in the NAND?
Could still be BGA failure on CPU as it does not always need to get stupidly hot for BGA to fail. Would expect nand to give issues over wide range of function.
either issue is same result in terms of mainboard no good ...
Thanks for fast response guys, so as i understand, there is no possible fix without disassembling it, and it may need new motherboard, yes?
What's the version of the radio?

G'day all,
My HTC P3600 has been nothing but problematic since I purchased it August 2007. The screen has been replaced twice and I thought everything was on track.
NOW I have noticed that the vibrate function no longer works at all. Not for phone calls, sms alarms, nada!
The people who have been repairing the last couple of times have had the phone for 3 weeks and now tell me it's something to do with software/firmware specific to the vibrator hardware.
Has anyone heard of such a thing, or could possibly explain to me?
I am running bepe 0.79 OS: 5.2.1908 (Build 18508.0.7.0) but it also doesn't work with the factory release OS from HTC
Regards,
WangChung
sounds like it broke from the inside. i don't see how a vibrate function not working could be a software problem. especially with two roms.
what kind of screen problems have you had btw?
Thanks for your response viperx,
I agree with you that it sounds unlikely to be software related for the the vibrate not to work. Personally I think the mob repairing this device for the 3rd time have absolutely no idea what they are doing and are just trying to bull$h!t me and stall for time
As for my screen issues previous to this. The "Start Menu" activation of death I guess you could say. The ubiquitous On of Off of the Start Menu finally resulting in no screen response at all.
The entire screen was replaced the first time, then they told me on the second occasion that it was only one component or layer of the screen that required replacing on the second failure. Personally I've never been comfortable withthe people repairing the device, but when you buy it overseas and have no local warranty, little you can do I guess.

I've had the start menu problem, not bad though. i'm hoping it won't give in. might be becoming more frequent though.
good luck with the repair shop then

I agree with viperx, I flashed my device with many different rom, official and cooked, and never had problems with hardware components I think that the people who have been repairing your device last time, forgot to plug some connector ( of they'r brain ) hope they hadn't broke anything...
Good luck
Sorry for my english
Hello
I have a problem with my touchscreen. The lower part is not working like it should.
I found a video with on youtube explaining the problem :
youtube dot com/watch?v=LxeIvr7xV9w
What is strange is that when i flash a new rom (1.5) the hero is working good at the begin , it is after i install some apps that the problem begins.
Is it software or hardware related ?
Anyone got the same problem ?
It gets worse over time, especialy when the divice gets warmer. After cooling down, the screen reaction is better.
I had my screen replaced for warranty. Device was picked up and returned within 10 days.
Very good service.
I have noticed that my HD2 tends to freeze under load under any OS. It doesn't matter whether I'm running android from SD or NAND, or WINMO. It runs fine during most tasks but anything which increases the load such as surfing the web or playing a game will freeze it. It seems the freezing is related to overheating. Once the battery temp nears 35-37c, it will almost certainly freeze. When its even a little warm, all it takes is about 30 seconds of angry birds to freeze it, if its cold, maybe 15 minutes.
I have tried everything from task 29 to trying many roms and different radios, even the stock TMOUS rom will freeze under certain conditions. My phone is not under warranty and I don't know what else to do.
Does anyone have any advice?
What could possibly be causing this?
And your reset button is what color?

The reset button is the little one under the battery cover, but don't worry about that question - it's really not relevant and will offer no suggestion as to how to help you.
It sounds like it overheats far too easy. To me, because it happens with any OS it sounds like a hardware problem and I'd send it away for repair.

That's what I thought. Any idea on any other potential causes? I wonder which area of the hardware is faulty. Ugh, I have a feeling this will be an expensive repair, maybe its better to just get a new phone?

same thing happens to me too....
especially when running a rom for the first time.....
phone gets hot especially the bottom half of the touchscreen.
Most likely a hardware fault
I had similar problems. Took it back to the supplier and they replaced the motherboard.
Seems to work fine now.
I suspect (but have no proof) that the problem was caused by the stand I was using. The micro-usb connection was very tight and I had to wriggle the phone to remove it from the stand. Maybe I broke or cracked a connector on the motherboard.

Yep, that's exactly where it gets hot...
Anyone know how much HTC would charge for a repair without warranty?
Ugh, just when NAND comes around and makes this phone really nice, mine decides to die...

Was your phone getting warm while crashing?
whaaaat
my hd2 crashes when i boot winmo, it doest get hot.. it just fails..
but when i go to start very quick, that doest happen.. i flashed it.. same prob. stock rom.. same prob? when i boot android NOTHING happens.. just... nothing.. it doest even restart.. what could be the possible couse of this failure?
greetings
The reason why it is getting hot at the bottom of the screen is because that is where the whole mainboard is with the prossesor and the NAND memory chips right together almost. The processor/CPU is what gets hot and over a period of time of getting exsessivly hot it begins to break down the connection of thd CPU and the mainboard. HTC kind of screwed up and did not incorperate a very good cooling system or heat disapation system in the HD2
if you have the possibility send the phone for repairs, if you still have it in warranty. If not, HTC will charge you with the cost of a new motherboard, that should be around half the cost of the phone. Also, I strongly believe that because the nature of the problem, HTC will not attempt any type of repair on the old motherboard.
As a last resort, maybe some service centers could be able to attempt some sort of ghetto-style repairs on the old motherboard (if you are willing to try untill paying HTC for a new motherboard). As I described here, i found a solution to my problem (similar to others) and so far it's working.

I also know the problem tends to be degenerative, I'll return and post to that topic the steps it takes and how it gets even worse.
erhm....
my hd2 is somehow stuck in carkit mode, right after completely booting up it turns to carkit mode.
i've allready tried a few roms and it keeps comming back, so my guesses are that it's a hardware problem, anyone familiar with this problem?
I had the exact same problem with my HD2, this issue might have been caused by various reasons. You either have dust/dirt on your sensors or the sensors are damaged.
Try disassembling your device and cleaning them, if that don't work try an android Nand ROM, on some of them you have the option to disable the sensors and you don't have to deal with Navitel. I've been experiencing this problem long time now.. going Android was the only option I had left.
In a lot of cases this was caused by a dodgy USB socket, so before dismantling the phone, give the USB a clean with a dry toothbrush
Lol, never thought I'd see a reply on this thread
But the problem got solved over time, so O guess the sensor was dirty.
Anyway my hd2's antenna is almost dead so I was forced to change my daily device.
But android anyway is a very nice solution for the hd2's life in general
A fully tweaked up hd2 isn't much slower than my current stock One X
I guess time will tell how this phone will end up XD
My htc doesnt turn on or work or charge unless i make it really cold like putting it in the fridge or freezer for a couple of mins, then it turns on by putting in battery and sticking in usb (because my buttons have snapped the flex cable) anyways it turns on and i have this russian rom flashed by previous owner, i managed to sync it with active-sync and i clicked explore it has wierd folder names like "?????" i click delete but windows doesnt let me because it says the filename should not contain "?". Then after a couple of mins maybe 2mins the phone switches off then vibrates 7 times then sometimes loads at htc splash screen?
and to make it work again ill have to make it cold again???
some details
Its a T-Mobile Version
The phone doesnt get hot?
its running windows mobile 6.5 daltt roms
and i updated the radio to Leo_Radio_15.40.50.07U_2.12.50.02_2
I think your battery is missed up, you need to replace it with a new one. try ebay.
as for the files with weird names, if they were located in your sdcard try to run checkdisk or scandisk from your computer to fix those errors.
you might want to reflash you windows rom and format your sdcard after this to prevent it from happening again, but don't forget to backup first!
Thanks for the reply!
Thanks for the reply by the way i havent got a sd card in the phone and i really dont think its the battery problem as it charges it up fine?
i was thinking i need a new motherboard as cpu is overheating but im not sure thats why im asking!
My HD2 acted like that (needed to put in fridge to work). Sent it for repairs and they replaced the motherboard.
Cheers
Yes mainboard CPU BGA issue probably.
you might find spares on this site or try buying one with a broken screen & you will have mainboard & button parts you need plus other parts can be sold on to recover costs ...

Ohh well i dint really want too spend money...
anyway what about that guide the one about thermal problems htc hd2,
would that work??
can you also tell me where i could find a motherboard thats working in the uk and could you give link please
thanks.
Please ive got no phone
ive got no phone!
please i really need help, dont leave me.........
The thread on solving the over heating problems is a thread on how to make a different heat sink for the HD2. And also heating the processor up to maybe solve the issues of the balling of the processor as the processor itself can not be removed without making the rest of the main board unusable. But the process that you must go through in that thread is not just for your average Joe to do. If you mess up you will be forced to replace the main board. So my advice to you if you are not skilled at such technical repair work is to just buy another mainboard or a HD2 you can harvest the mainboard from, oh and it needs to be a mainboard for the T-Mobile version too as that is what you have.
I have a personal theoory about why the freezer trick works. First is the obvious thing that it cools down the CPU and NAND chip and allows it to operate for a short period until it warms up again. The second is that cold makes matter shrink slightly, those causing a CPU that has lost some of the connections to the balls under it that make contact to the mainboard to temporally become reconnected.
newbie guide please
Okay I think for my last resort I'm going to do the guide in the thread but can somebody PLEASE make a super easy newbie tutorial on how to do it (I know it will take time but please),without the expensive equipment that I don't have. Could I use a lighter or a candle or what about the oven or a hair dryer anything that would be at home please.
Oh yeah who ever provides the information that works I will donate money to you! Only if it works (yes I do want my mother board back)
Too Late
