Freezes and Reboots (Hardware issue)

I have bought a used HTC HD2 which freezes very often. Unfortunately I found out that the device freezes when it gets more than 36.5 degrees. I am incapable to make call which take longer than 5 minutes- its very annoying. The problem is, that I can't send the phone to HTC in my country because I got the device from Germany. So I have my warrantly in my country.
The problem exists in Android and Windows Mobile. I have tried many different ROMs. I've read serveral posts about freezing problems and it is definitly a hardware issue.
Is it possible or has someone fixed the freezing and reboot problems with his HD2?
I am very sorry for my bad English.

probably not, had the same overheating/reset loops issue, finished having mainboard replaced under warranty, no problems since

The problem is, that I have no warrantly and replaceing the mainboard cost 100€ or more...
Is there any way to disable the temperature sensor that the mainboard doesn't reboot?

Looks like you bought a flawed phone. Can't you just return the phone to the vendor you bought it from? Or insure it, and claim on it? At one stage I had my phone covered by house insurance, phone insurance and my bank also had it covered as part of a premium account I had with them, surely you have something along those lines you can claim though?

The problem is that I can't return the phone
I need to fix it myself but I don't now how to do it.
I found a post which maybe help but I am afraid to completlely damage my device.

had a same problem...
my solution was screawing the middle battery pin under cover...
the hd2 have must have Temperature senzor...
the hd2 have 3 pins under battery cover, 1 = +, 3 = -, and the middle pins is the 2 = ?
i think the middle or the pin nr. 2, is same as ACPI in desktop or notebook, Advanced Configuration and Power Interface,
Operating System-directed configuration and Power Management,
so if your middle pin is screawed, the powermanagement tell to device stop boot!!
or if the pin dont make a contact with battery - the powermanagement canot corectly detect the Temperature and the hd2 owerheat, then randomly restart...
its only my teory, my middle pins was screawed, im take it to the right position and my device worked well... but i want more and more and i broke the middle pin
after that the hd2 boot, and worked but when i want to do restart dont want to boot...
now my hd2 is in service center... so for all i want to say:
warrnig!!! dont youse the power or angry when u want to screaw the pin back
its only my teory, im not the electro technic...
sorry for my english, but i think everybody understand what i want to say

Has anyone done this? Or can anyone please share a pic with the three battery contacts because I don't know what's exactly the right position.

if it's overheating that easily, the motherboard needs to be replaced. Not much we can do to help.

Its very strange because 36.5 degrees is not very hot and there are HD2s which work when they get 50 degrees. I don't think that something is overheating. In my view there is something wrong with the temperature sensor. Maybe the sensor is reporting that the device is overheating which isn't true.

Hi,
my HD2 crashed when temperature was more than 34,4°. I observed that this problem gets more and more often. It began about 2 or 3 times a week and ends with crash after 2 min using the device. I gave it to sevice center and they replaced my keyboard. (btw: all Software using a hardware-dependent key is no mor working).

try using some "Tesafilm", and put it on the battery there where that pi is before screwin it off... maybe that helps.

@mm2700: You've got a PM! I had nearly the same issue here in Austria with a German HD2.

How do you measure the temperature?

Black screen of dead ---SOLVED!!! - in test period

First the problem.
Like many others HTC HD owners and I encountered this problem 2 days ago (i have nolonger waranty). i just was connected to my computer thru USB for couple hours, when i tried to power it on, the phone display dont comed on, but the phone worked fine (i maked couple conversations. After that i started to read about this problem, a lot of problems, but no solutions.
I try everthing - put in refrigerator (it worked until i turn off the display, pulled the battery for the night, and one bucket with operations without effect.
i install mymobiler and i was sure that my HD is working without display, then i disassemble the phone and checked the connectors, but no effect either.
i am radiocommunication and electronic engineer, and i don't give up so easily
i pulled the main board, and blowed the main board with hot air flow solder machine (i blowed exactly all over the shielding, from the bottom side not SIM card side), i wait for cooling then asemble the phone, and voala "Its alive"
NOW I AM IN TESTING PERIOD. I WILL WRITE WHEN I AM SURE THATS WORK FOR ME.
i have no pictures but i will make when i disassemle the phone again, because now is not fully asembled.
cheers!!!!!
p.s. i am sorry for my bad english
p.s. i am so happy trallllalalalalalal

It's not uncommon to see bad phone soldering on HTCs phones. Guess their factory isn't working right. Good job btw.

72 hours later everything looks great, the screen works perfektly, touch too, wireless communication too. i will post after few test again.
p.s. its look like my battery now have better handling....

6 un grande!

Wow!!! It's a good new. I had the same problem and I will try your solution. I hope it works on my phone.
Cheers!

I have problem from another type:
The problem is with signal. It was perfect until one day, the 3G has gone & then start losing the signal some times 3G return poor or strong, I take it to the HTC service center in Saudi Arabiya & the told me you have to change the main board then they do it but the same problem still there.
Now still have the problem even after change the main board, is there anything if have to change it or do it???
Note: it files down from me before this problem happened.

did you try to change the radio???

This could be caused by bad SIM card. Did you try another SIM? In my country it's not unussual for SIM cards to start malfunction out of the blue. Also, check contacts for grease or dust.

Hi, ssory for a stupid question, but what is "solder machine" with hot air flow? Is it idustrial fan? If yes, it can give to great temperature and can damage motherboard.
Was your idea to solder again all solder connections and roads?

the solder machine keep one temps at all around 280 degrees celsioum, i thunk the chips can be demaged with temture about 340 degrees, ofcourse it depends of how long time you will blow over the pcb. i don't resolder all tracks and elements (i have no such technology in my laboratory), i just blowed the shielded part of the mainboard, because i know that i can blow some smd element and they are very tiny.
p.s. i use this JBC AM6850 solder mahine
p.s.2 yes it was my idea - it is better than to do nothing with this PDA and throw it in the cupboard
The solution still work for me...

bueno suerte...

Yesterday i dropped my phone (exactly face down)- now the LCD screen show only (right side about 1 inch) bright light and remaining parts are blank. but it works fine - as when i get calls it vibrates. Pls guide me.

HD2 hardware failure?

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...

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.

HTC HD2 Freezer Trick Only Way to Make the phone work, Could it be overheating??

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)

Htc hd 2 random restarting after installing WM 6,5

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?
