Urgent Help: HTC P3600 Freeze!

Hello,
I am owner of HTC P3600 from last 12 months and i used custom roms too all was working fine and before 2 days i found that whenever i leave the HTC for few hours it hangs and when i press the standby button to wake it up nothing appears on the screen and i have to reset it to start it again.
Updates:
Ok i re flash the Hard SPL, Radio and Rom and until now (in last 24 hours) it don't hangs.....
Update 2: I think the battery is the problem as the battery time is decreased from 3 days to just 1 and a half day and it freeze now while charging....
Any solution? anyone experience the same problem?

Help please with your views...............

I have a similar problem. My HTC started crashing after a rom update. However, i think it is not crashing due to software...
Well, the software is more CPU demanding, so it heats more than before. Also, i started using backlight properties set to high (i need to set to low again), which again highly heats the PDA. Finally, when charging the battery tends to get very hot. All this put together causes the CPU to overheat and crashing.
At least, from my experience, when it crashes it is always very hot.

Sounds like a radio rom problem. Try to reflash radio.

Thanks for the advice!
I will reflash the radio rom.
If it solves the problem i will update my post here so everyone else knows how to solve this kind of problem.

it helped ? reflashing the radio rom ?

lol you ****up your phone hahahahahahahha

No, it did not helped. Probably it is an hardware problem.
The pda was intensively used connected to the computer, because it was used for software developing.
I think it is broken, hehe.

HD2 overheating, not charging and rebooting - temperature monitoring

During the last week I experienced some strange behaviour on my HD2. I want to point out that in general I am very happy with it, but now I wonder whether my device is faulty or weather this is a feature.
What I have seen:
- my device had some sudden reboots when using it in my car, charging with car charger
- this happens only when outside temeperature is close to 30 degrees C or above
- it happens after some time (10 - 15 min) using Navigon or even just doing Bluetooth calls
- it usually stops charging the device, the LED is then blinking green & orange, then reboot
- I recognize that the device is very hot
- after cooling down it has lost the power settings
I found two other threads dealings with similiar effects
http://forum.xda-developers.com/showthread.php?t=707477
http://forum.xda-developers.com/showthread.php?t=627884
and now want to do some detailed anaylsis here. I installed BattClock (great tool!)
http://forum.xda-developers.com/showthread.php?t=612083
to monitor the battery temparatur and found the following:
- idle phone (office, not charging, 3G connect, push mail activated): 25 - 30°C
- phone in use (office, not charging, checking mails etc): 30 - 34°
- idle charging (as idle phone, plus charging): 30 - 34°
- phone in use, charging in car, summer temp 28°): temperuture rises up to 47°
The last case ended with a reboot, when coming up again the temperature was 47.1 degrees, green / orange was bblinking and charging has stopped. Before crashing the temperature raised from 33 to 47° within 15 minutes.
Can anybody confirm whether he can run the HD2 wíth 47° and above? I would like to understand whether I shoul return my phone under warranty or whether this is a feature. 47° is high - though I do not think too high??? I also got the impression that this issue is coming up more and more frequently with my phone and as the summer just has started this could mean I need to stop charging while driving. How to use navigation?
Any comments or ideas?
Regards Hase

Well Hase,
I've seen this a few times in the past when driving running CoPilot, Bluetooth, screen bright and charging.
In the last week, with a new ROM base and significantly warmer weather, I've seen this with just having the phone in the car charging.
Very interested (and actively hunting) a manual underclock to see if it helps.

I don't think this is a defect, but it does happen.
I've noticed it too a alot during the NE heatwave in the US.
I'm waiting it out for now.
47C is not too hot though, although maybe there could be some kind of feature with the processor?

Yeah I've noticed it too. I was driving in my car running Bing Navigation with no problems for about 2 hours with the windows up and the ac on in my car. 10 minutes after I opened the windows when it was 101 F outside bing maps would randomly shut down and other apps would not even open. Closed the windows cranked the ac and held my phone in front of the vent to cool down and it went back to normal without even having to soft reset. Seems like a feature to prevent damage to the phone.

I would guess its some overheat protection feature with the processor, as its really the latest, which means sometimes it may get too hot ( you know, 1GHZ is really fast and thus may generate much more hrest than normal slower processors ) . Just like Intel's processors, which also shut off when the temperature rises over a certain programmed known "safe" temperature and reboots the computer, in hope that when its started again, it would be cooler. As for battery temperature, the cpu may be even hotter than the battery's temperature and thus it may seem that the phone shut off at a low temperature, but in actual, the processor is REALLY hot. And as its a mobile processor and its known that the second hottest factor is charging/discharging the battery, charging may be temporarily disabled until it cools down to a "safe" temperature to prevent overheating/buring out other components. But that's just what I think. Best to check with Qualcomm or HTC if possible as it may also be a defect in the phone. Hope this helps.

I haven't experienced any reboots but I have had problems with my HD2 locking up due to excessive heat.
Leaving it in direct sunlight means I'm unable to unlock the phone due to the lack of response from the screen.
Yesterday my HD2 was charging in its cradle and wi-fi was on. The device got hot and became unresponsive and I ended up putting it in the fridge for 10 mins which brought it back to life.
The HD2 definitely has an issue with high temps, the screen in particular.

Have you tried LeoCpuSpeed?

I have had this problam as well. It also happened with my Touch Pro 2 when in the car, sun, Copilot, etc...
My fix was kind of a lucky guess. I have AC vents that blow on the windows of the doors when it is on the defrost setting. I just have the windshield mount sitting kind of over the vent for the drivers window. It is not quite in a direct line with the window, but enough AC comes out of it to get to the device and cool it.
When I do this, it goes from a rather toasty to the touch to rather cold actually. Even with the rubber "case" on it it keeps it down to a reasonable temp, if not below, with it charging, GPS going, bluetooth stereo and WMP all going.
Since popping it into the airflow it has not even gotten warm let alone started the warning flashes and such.
Kind of an obvious one, but those are the most often overlooked so I figured I would add it in.

In fact that was my solution too. I changed my cradle using one putting the HD2 in front of an AC outlet and now everything is fine. Just make sure the lower part of the HD2 where the USB cable is connected is not covered by the cradle or any cover as this is the place where the cold wind has to blow. Battery temp remains well below 30° C, if driving longer distances even below 20°. I am not sure whether I will get too low? And I do not now yet what will happen in winter when we get it freezing cold and heating will step in.

Does anybody have tried underclocking yet? Would be good to now whether this could be an option too. Sometimes even using the HD2 on hot days (without charging!) gets the temp up to 38° C plus. Best thing is not to hold it on the lower part.
I am wondering that still only some people get this problems. Either everybody is ACed (not poss in my convertable) or the problem is only with some HD2 or some ROM. Has anybody noticed any other strange behaviour after an overheating occured? I noticed some issues during the last months which I could not yet connect to any other reason. I am not sure whether I have had overheating bevor these occured the first time:
- all of a sudden bluetooth connex to my car was not poss any more
- all of a sudden pocket xls application and the note application got very very slow
- all of a sudden POP connect to google Mail did not show any mails any more.
These effects did not show up the first time all together, they came one after another, one per month since March. And probably I have had overheating earlier without even noticing it

Hi, i have the same problem with overheating ... it stop charging when Battery Temperature reach 45°C. Battery PINS are all OK and clean
First : My Leo has Radio 2.11 (2.12 same problem)
OEM 2.10 (My own ROM)
Today Test : Go back to original ROM 1.66 (Radio 2.06) and my HD2 does not overheat ! Strange
I can see with PowerGuard that the charging current slow down when the temperature go up and reach max 42.3°C
Tomorrow Test : Radio 2.06 and my ROM with OEM 2.10 ... if do not overheat then i try with Radio 2.08 (more RAM ... TMOUS) ....
to be continued ...

Today Test with Original Firmware 1.66 and Radio 2.06 has problem too
Ordered new original Battery from Brack.ch ... when battery comes make new test to see if it's the battery or HD2.
Strange is that the battery is not so hot but the charge circuit of the HD2 is very Hot. (Hottest place is between SD CARD and SIM Card)

Hello,
I experienced the same sudden shut downs (not reboots) during the last days as well ("hopefully" only due to the very hot weather). And none of my POP3 account seem to work right now!
The internet connectivity seems to be okay, and of course I haven't changes any mail settings... but I cannot receive or send any mails. I get no error message when I try to receive mails but when I click on the new mail button my HD2 asks me to set up a new mail connection!
Any solution found to this problem?
Kind Regards,
DW!

On my side the problem is a bit different. POP3 seems to work fine (also no errors) but does not receive mails. Sending is o.k. And this problem is only with gmail, other accounts work like before.

I had my HD2 heat up to about 48degs when in use while charging it. No problems encountered. Perhaps its defective. Send to HTC for repair?

Hmmm, that's no problem on my HD2 - Mobile Excel is opening as fast as ever...

I have now deleted 2 of my 4 mail accounts and re-installed them; the other 2 I simply have re-installed withour prior erasure - and this seem to do the job! Indeed I have done this more than once now, but 3 accounts now already received test mails... the 4th is a freemail account which I can only use every 15min. via POP3/IMAP...

But what was the outside temperature? I think the overheating has to do mainly with using the phone (gps) while charging in a hot environment inside of a car.
Just charging the phone shouldn't use the processor to any significant point.
Just my $.02.

I could not believe it what I read here, but now the high temperatures in Austria caused the same problems on my HD2 when navigating in my car. HD2 after 2-5 minutes blinks orange-green (no loading) and after maximum 10-15 minutes crashes.
Unfortunately I have to rely on navi-function for my upcoming vacation. No solution to place the HD2 in AC-stream in my car with this stupid original HTC-Car-Navi-Holder.
When driving in the heat of noon I don´t even have to switch it on, just mounting into the loading-cradle is enough to make the HD2 crash after 10-15 minutes, only 3G on, nothing else (no BT, WiFi, HSPA, no app running etc.)
Until now I was quite satisfied with the HD2, had no crashes or malfunctions so far, but now I am really fed up with this piece of sh.. and I don´t think there will be a hardware or software-solution (except swichting it off) since the HD2 is malconstructed.
This was the last time I bought a HTC product ............... Crap at a high price I can have with an iPhone too ................

Help with my HD2 [Freeze issue] please

Suddenly and strangely my HD2 has been freezing and rebooting by itself for no reason (that i know of) and it heats up a bunch. My freezes generally happen when I go on YouTube, browse the internet, watch Transformers, or switch to Android.
I don't know what is causing this at all. I have over 10gbs remaining on my SD card and still a good amount of memory on the device so I don't know if it is a memory issue, I also always to task killer to shut off unused apps and keep a low display (both on wm and android)
I'm using the stock HD2 rom, all I have is HSPL 3 and for Android I'm using darkstone froyosense v3.2
If anyone can help me I will be extremely grateful

The first thing that comes to my mind is your battery. Does it charge normally or is the LED sometimes blinking from red to green and back? How about battery consumption? There must be something wrong with either your battery or the connections, because that causes the heat, certainly when you're using battery draining apps like YouTube, Android, etc.
Hope this helps.
regards, Kuzibri

Try and remove the memory card and see if the freezing goes away.

sounds like overheating, search here on xda, there were few threads on this,
in the meantime install BattClock and check if freezes happen in correlation to battery temp.

my HD2 did the same thing. I eventually had to get a warranty replacement. Mine would freeze on occasion and then it just froze completely. Doing a Task29 and flashing a new ROM did not help.
if all else fails your best bet is to get a warranty replacement from your carrier

Yeah, that's what I'm considering doing.
As for connections, I've noticed that my input socket on my phone for my usb charger cord isn't grabbing the cord as it should. when i charge my phone the cord easily disconnects and wiggles around

I sent my HD2 for repair, now got it back, but still have issues!

Hi,
I recently sent my HD2 for repair, because it had heat issues and GPS couldn't get a lock. Now I've got my HD2 back, but when I try to use the GPS, it either doesn't find signal at all or when I use for example Google Maps or TomTom, it causes the phone to reboot. I've used the QuickGPS software to get a faster lock, but this doesn't resolve the issue.
Also the heat issues still exist. Whenever I wan't to watch videos etc., the device heats up a lot and causes the phone to reboot. The bottom of the device gets always very hot.
The service center did change the touch screen, chassis and installed "HotFix-update", but these didn't solve anything. Does this mean, that the service center changed wrong parts? What actually can cause heat and GPS freezing/rebooting issues?
I'm now using stock WinMo 6.5 and the ROM version is WWE 3.14 and the radio version is 2.15.50.14.

Watching video or any activity that constantly uses the screen also uses a lot of battery power and it will get very warm/hot.
Have you tried any other software to test gps usage?
Do you have ALL the settings for Google/gps/locations and maps set up in the correct manner?
Do you have a case or any other protection on the phone - if so remove it
If your ambient temps are high this just compounds any issues with heat

first time to hear that
will be very carful

I was able to get the GPS working fine. However it doesn't work in Android. If I turn on the GPS and the GPS starts looking signal and when it founds it, it causes instant freeze. This is a real mystery to me. What can cause this issue? WinMo 6.5 with WWE 3.14 and 2.15.50.14, GPS works great, but when I switched to nand Android RAFDROID 4.0.2, the GPS doesn't work anymore. Or it does work, it does look for the signal and everything, but when it founds it, it causes instant freeze. Screen stays on, nothing happens.
I should point out, that I was having this same exact problem, prior the repair. And some time ago, I was still able to get the GPS working in various versions of nand Android. But now, whatever Android build I use, I have the same issue. Something in Android is messing the GPS module.
The heat is not that bad of a problem in Android, so I can live with that. I'm not using any bumpers or any other protection.

hi if you sent it back to htc repair center contact them again and say problem still there they should replace phone for you

Send it back for replacement. Yeah the phones become warmer under certain conditions but I use mine to watch hour long XviDs one after the other in the sun and I have no such issues. It takes constant downloading of data with GPS locked and loads of apps open for mine to warm up! Sounds like you need a mainboard replacement to be honest, surprised they didn't switch the boards the first time and test .
I've never had mine reboot or go crazy on me due to heat, at worse the battery temp check kicked in in WM while charging to switch off charge (flashing orange led) with my cheap Chinese battery
Sent from my Nexus One

I have heard that the high temperature causes by 3g... If you use 3g data, try to disable it and then try gps and movies again.
The conclusion, btw, is to sent the phone back for repair or replacement.

Same here my brother's hd2 working perfectly fine but mine every time temperature exceeds 33 celcius gps cause phone reboot and if i manage to turn gps on can't find fix

I got my phone up to ~42C while I was working in an auto garage and I still don't have reboot. If your phone reboots at a certain temperature, your phone is defective, and try to get it replaced by warranty, or you could try to modify your phone to fix the issue: http://forum.xda-developers.com/showthread.php?t=982454

[Q] HD2 freezing, posibble heat problem

Hello guys, hope I can get an idea here to solve a problem, i'm at the end of my hopes.
So, I got an unlocked EU HD2, been using it with Android mainly. Some months ago the touchscreen broke, I got it changed under warranty.
Since it came back the phone freezes under heavy load the image is stuck on screen, hardware keys don't react if I press them and if there was any audio playing at the moment of the freeze i hear a buzzing sound (possibly the last of the audio buffer playing back constantly).
By "heavy load" I mean flash, Youtube streaming, games (jelly defense) sometimes offline video playback, google maps specially when caching areas for offline use, when GPS locking. It's not CPU load it seams but high current drain load possibly (CPU stress test runs for long times without issues).
I mentioned possible heat related cause because if the phone freezes and I reboot right away it freezes again quite shortly but if i let it cool down and then boot up it takes longer for it to freeze.
This appears in multiple android builds, it is more frequent on ICS builds (or it seems under high GPU use), appears in WM6 also but less frequent.
I got the phone back to stock state and sent it back to service with the information above (minus anything android related) and they sent it back saying the problem did not manifest. Indeed in WM6 with stock software it seems that there is not much that can stress it enough.
The phone itself does not get noticeably hotter than before touchscreen replacement but the screen itself seems to heat up less, it might be that it used ti dissipate some of the heat before.
So anyone got a clue if there is something I could do ? I'm willing to take the phone apart to solve the problem but not without a clear plan in mind.

It is an already well-known problem with CPU heating failure probably because of BGA balls between motherboard and CPU.
The only long-lasting solution is replacement of motherboard, unfortunately...

Thanks for the info.
Alas, no good news, was hoping it may be a heat dissipation problem. I wonder then how this may have appeared after touch screen replacement.
