temperature problem

I tought I had a boot problem on my Elf, after days with sw related troubleshooting I found out that the CPU crashes with normal temperature. At startup it stops right before you have to type the PIN code for the SIM card, unless its cold - then it works like a charm! Now we live separate lives, me in the livingroom and my htc in the fridge!
Sounds familiar to anyone? I expect that some hw replacement have to be done but I have no idea what could cause this fault. It came suddenly at normal use.

Are you serious? You're actually saying you keep your phone in the fridge??!! For real? And as unbelievable as that sounds....it works fine there....and crashes the moment you get it out?? Like for real??
Are you sure you didn't flash a new rom or something...or changed something after which this has started. I've seen some weird issues...but this one surely takes the cake.

lol... sounds funny !

Seems complicated but you can always move to the north pole, hitch a ride with santa when he comes................
Ok enough joking around and let's get serious: if you can take the touch apart completely because you must have it filled with dust etc. and it heats up because it doesn't have enough refrigeration result: power off or crash. There is a tutorial on how to do this somewhere here. I had the same issue with a nokia some years ago and even used bluetooth to make calls from the fridge untill someone told me why.... you can't do it wrong there is a tutorial

disassamble
Yes, I've sees the turtorial and saved it as a favoritt! I also disassambled it once to see if theres a obvious reason for this behavior, but it seems all good. I might try again and look for hotspots, and clean out whatever I can find. It is over a year old, so it would be believable that dust generates the overheat.
By the way, I allready live half way up to the north pole at aprox 66 degrees north - northern norway! Not so cold to day, +6 Celcius!

lol...ok then. All the extreme temperatures apart.....If your device is over a year old....might I suggest a hard reset then. If could be some phone malfunction. A hard reset might just put it back together again. Of course....do backup all your info first.

yeah
I did the hard reset early before I had any chance to do a backup as a init to my trubleshooting. It might give a tad faster phone, but that could be because there is nothing more to process!!! Sees like the temperature is more critical. It works fine for an hour or two then its right back to the frigde...
I did suspect the battery, that it could generate to much heat because of its age, but the batterytime is all fine and it doesnt feel very hot!
time will show... Just waiting for the Touch HD to get over its "publication-over-price", and the my Elf will live happily ever after in my drawer (Sorry if thats a four letter word in this forum)

away from the funny posts above a technical question did you use any program for overclocking before this happen eg battery status

No overclocking!
The phone is all original settings and software. It happend when the when I was on the phone and the "battery low turnoff"-interrupt occured. I put in the charger and tried to restart the phone, but it stopped right before the PIN-code meny. The backgroundlight responds to the buttons when it crashes. It seems that its just waiting for the SIM-card init-rutine.
But if I've coold it down and get it up and running, it still crashes when it reaches normal temperature. As the temperaure rises it respons slower and slower at buttons etc. In the end it all stops and it stays "where you left it"! The on/off bacgroundlight function still remains intact, but you cant use the power off function on the same button. Only soft reset - and go to bootleg(RGB-window) - and then power it down with the power off button. Then it goes to fridge again...
I shall try to clean it inside later on even though it seemed all fine when I had a look earlier.

Replaced the motherboard
If anyone out there still is interested; I sendt the phone to a serviceshop some days before the guarantee time ended and they gave me a new motherboard in the phone. So insted of having a broken Elf in my closet I now have a up going and working elf in my closet - for what its worth!!

LOL! ok well I live in Africa.. summer temps. from 25 - 35 Degrees C are the norm and I've never had a problem like that, hehe.

My HD2 get so hot, then freeze!

I'm not sure if anybody here has same problem as mine. Here is the problem. After watch movie on my HD2 for half an hour, the device started getting warm and hot. It then froze and restarted itself. Then it would stuck on the logo boot up and that was it. I had to take the battery out, waited for 5 to 10 mn to give it time to cool down. Then everything went normal. This happens to me quite frequent now. It wasn't like this when I first bought this. I used to watch movie for hours without any problem.

i had this problem. my hd2 actually was burned on the back near the micro port!
search for hd2 fire to see the story.

I have same problem, who know to repair please help me

if phone is under warranty, get it replaced. did you void your waranty?

Are you using the original charger?
If your mainboard overheats just once, it will never be the same again. It's time for a warranty replacement!

sounds like it has a drug problem or is going through menopause. LOL! I had to sorry carry on.

mine so the samething too , if the back get warm up the phone freeze then restart . do the same thing with NAND too . his there any other ways beside warranty . cuz i dont know if mine phone still under warranty . i got the phone in last father's day so it havent been 1 year yet

If it has not been a full year sense you purchased the phone then yes you still have a warranty. Your issue is probably hardware related cause once a HD2 starts getting warm a lot it starts to slowly deteriorate the connections between the processor and the mainboard. The more the heating up of the processor the more and more it detiorates the connections. It finally reaches a point where it will start rebooting it self because it is trying to compensate for the lack of responses from the failing pathways. So it sound like you are experiencing this problem now. So I recomend you do an exchange while you are still under warranty.

i suggest checking the battery pins also, make sure they are straight and shiny!

HTC getting hot and freezes.
I have a T Mobile HD2 and I have WMO 6.5 on NAND and Android on SD card (16 Gig). Mostly I using android, the main problem is after like using 10 minutes of WIFI the phone gets very hot,I mean really hot and then it freezes. I have to remove the battery and wait about 10 minutes for it to cool and then place the battery and boot again. I am not sure what is causing the problem, if it is hardware then nothing can be done but if it software I am sure there is a solution. Any help is greatly appreciated.

Hi,
i've the same problems when using the HD2 for car navigation. When the phone is in the front panel holder and sun is shining, the phone freezes or reboot after a while. The phone itself isn't very warm so i think it must be something with the mainboard or the antenna. I tried with carcharger and without carcharger, same result.

search xda, there has been quite a few threads on Leo's overheating,
in short main two reasons are bent battery connectors (you can DIY), or defective mainboard (replaceable under warranty - been there myself),
to make sure the freezes or reset loops are temperature connected I'd suggest BattClock for WinMo (displays temp in statusbar) or Battery Monitor Widget for Android (keeps temp log)
if you lost all hope, and you're sure it is the temperature, and your warranty has ran out, and its definitely not connector related, then you could try checking here: http://forum.xda-developers.com/showthread.php?t=982454

what kind of rom do you use? What is your Radio?
is the battery genuine one?
what programs do you use?
some bad written programs will make cpu in loops, which lead to make the cpu runs into high frequency.
do you use any setCPU/overclocking?
my recommendations:
1) install any cpu trend program/ logger to see when the cpu runs into high frequency.
2)replace the video player you used for playing the video.
3)stop all programs that are not came with your rom.
if above do not solve your problem:
task29 / install fresh rom (not the same rom).

[Q] Freezing, rebooting and boot failing

Recently my HD2 starter to reboot often i didn't pay much attention at the time because the occasional reboot wasn't something new, however the reboots started occurring more often and eventually my phone started freezing, rebooting and boot failing ( freezes at the 123456 gogogo or when i try to load CWM, or at any point in the boot animation). So far i tried different roms but it didn't seem to matter, i tried Task 29, wiping caches, formatted SD card several times in different ways. Eventually i reverted back to stock rom and reflashed everything all over again but that also didn't work. Also my phone get's a little warm and if i leave it powered off for 5 minutes it usually boots on the first try. Is it possible that the phone is overheating and that is causing the problems, or is it something else?
I'm using the 576MB, MAGLDR 1.13, HSPL 2.08, CWM 5.0.2.6, Radio is 2.15.50.14

Your symptoms seem to be that of a CPU heating problem. There is a layer of heat conducting paste at the back (bottom-right, inside the phone) that might wear off with time causing improper heat dissipation causing the CPU to hang or reboot. If you know how to, open the back cover (not the battery cover, the phones back side) and apply a layer of heat conducting paste (should be available in most computer hardware stores, also comes with new Intel CPUs) on the part of the mainboard covered with a metal cover - lookup images or videos of how to open the phone and you'll understand all that I am saying.
Hopefully this would solve the problem. If it did not, you are in deeper trouble - time to look for a replacement for your ol' HD2.

Thank you! I will try, and if it doesn't work One X is coming soon

This may help in disassembling and reassembling the HD2:
http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked

I don't know where to post this, because i'm a new user and am not allowed to post this to the ROM-Thread (NDT MIUI 2.3.7 DEVELOPMENT V48.0|STABLE V6.0).
I have the stable Version of this ROM and had the problem that the device rebooted several times without any reason. And there was another problem: I never received SMS.
One time a friend called me 3 minutes after the device rebooted and told me he send me a sms minutes ago.
I tried some things and noticed, that it freezes and reboots everytime i received an SMS (the sender gets an receiving receipt but i never get that sms).
The Solution is:
Deinstall Avast Free Antivirus, including the Anti-Theft (Anti-Theft is listes as an extra app, first you need to disable AntiTheft's Root-Rights if you set it), you can then de-install it via Superuser.
Now it works

Everytime I charge my HD2 while driving and open some navigation program, it freeze
Sometimes I listen to the music and turn on 3G, the phone freezes
When I play jewels star more than 30 mins, it hangs
Not every case the bottom right of HD2 is so hot, but most of the time yes.
Thanks ph03n!x, I'll try to make CPU cooler to see if this problem solved.

My phone freezes :(

Hi, i have a SGH-I337M, with the AOSP 6.0.1 rom with root, since i can remember the phone had been pretty much hot, i didn't care much back then since i use it a lot but recently my phone started to freeze, like the screen freezes and i cant do anything, not even turn it off, so i have to take off the battery let it cool for 20 minutes and start it again, then it works about 10 or 20 minutes and then again it freezes i think it might be related to the heat. Also some few times my screen has turned green and then white and others few times i can see some sort of colored strings.
I'm pretty sure its hardware related but i don't know why it happens and if it can be repaired, do think ill have to change the whole motherboard?
Thanks in advance

Graphics chip may be the problem You shouldn't let your phone overheat like that I think it's the graphics chip (because of the color artifacts) You can try to reinstall ROM (clean installation) and flash another modem&bootloader, or even flash stock ROM. If that doesn't help then your graphics chip is damaged...There is 'repair', by changing motherboard, but it can be very expensive (if you don't find another S4 with broken screen or something else with working motherboard)

I already reinstalled the rom (clean install) and yupp, it doesn't work, the warmest place in my phone is between the sim card and the sd card, so i guess ill have to change my motherboard X_X
Anyway, thank you very much!

Have you actually tried other ROMs, or are you just a negativist?

You should get CPUTemp Xposed module and stop letting your phone get hot! I usually stop screwing around with mine when the temp gets to like 50/60-something Celsius. And like GDReaper said, don't be a Negative Nancy, be a Positive Paulie and play around with other ROMs!!

my original phone screen did things like that after a pretty heavy drop onto a tiled floor. it maybe a good idea to have a technician diagnose your problem before forking out money for parts that might not fix anything.

Thank you all for your answers, i did tried to flash some other roms without success (I still have the same problem) i am afraid to continue playing with roms since my phone sometimes freeze in the middle of the android configurations when i reboot my phone just after the new installation and i don't want it to freeze in the middle of the installation of a rom.
I think ill go to a technician to see what can be done about it, ill keep you informed what was the problem

LG randomly overheating and won't stay on - No previous heat issues

Hi, I have a LG K20 Plus. I currently can't turn the phone on, so I don't have much software information to give you. The phone was bought at T-Mobile (Metro by T-Mobile) and I had a SafeLink sim card and a 16 gb micro sd card inserted when the issue started. I have since removed both. It says Qualcomm snapdragon on the screen when it starts. It was also rooted and the bootloader is unlocked.
I broke the screen on my phone and I decided to do the repair myself. I have done about 7 or 8 screen replacements and I actually did this phone a year ago with no issues, so I felt I could manage this one as well. I bought an entire display (from ebay) and switched it out with no problems. Initially it worked great! I used it for a few days before realizing that I had no sound. I opened it back up and noticed the loud speaker had fallen out. I found it, put it back in, reassembled it as I normally do and turned it on.
NOTE: when I was reassembling it the second time, I actually tried to put a screw in a hole that wasn't a screw hole. I used a light to normal amount of pressure but I didn't force it. I think it's the hole where the moisture detector is. Picture #1
I turned it on and right after the logo screen I got a message that said "High temperature detected Powering off for your safety" and it immediately shut off. The phone does appear to charge normally but it won't stay on. I did a factory reset (I'm not sure if it's still rooted but the bootloader is still unlocked). I also switched back to the old (broken) display just to check if that would work. I couldn't see any difference in the shielding but I switched them just to be sure. I bought a new battery and installed it. I took a q-tip and 95% Isopropyl Alcohol and cleaned pretty much the entire motherboard, paying special attention to the battery connections. After each one of these things, I tried to start it with the same error message immediately upon start up.
NOTE: At no point has the phone every physically felt hot or even warm. I don't think it's on long enough for it to get hot. But something is wrong and I have no idea what it is. I, literally, took the phone apart, put in the speaker and put it back together in less than 5 minutes. Could it be I just bumped something and knocked it loose?
I searched for any information I could find both here and with google but there is next to no information on the LG K20 Plus. I did find some information on the LG V20 that had overheating issues, and that has been all the luck I've had. I watched several videos and it seems the solution is to apply thermal paste. But my phone doesn't have any evidence that thermal paste was ever on it. I went and bought some but I have no idea where exactly to put it or even if it's needed. Most videos showed people using some kind of aluminum foil but I'm not sure if that is safe. I have several old phone laying around and I managed to get some of the silver tape and a copper square thing but, again, my phone did not have these things to begin with. I don't want to start adding things only to make it worse.
There is a slight difference of the tape that is on my phone now (the display I just bought) as compared to the old one (broken display). Picture #2 Again, I have no idea if that means anything but I thought it worth mentioning. Picture #3 is how it looks now as if I were going to put it back together. Picture #4 is the part (don't know name) where the videos show to apply the thermal paste and the shielding.
I'm really at a loss as to what to do next and I can't really afford to take it in to have it repaired before next month. If anybody has any insight or answers as to what happened, I'd be very grateful for your help. I'm sorry for the long post. I just wanted to tell you everything I have done in detail. Thank you

If you're using Kernel Auditor or any other kernel adjustment simply reset to default and use only ondemand or interactive. There's also options for the thermal portion of the kernel, don't mess with those. If VCC or another thermal option was checked off turn it back on. Putting the GPS to the moderate setting (the one below high accuracy) will keep the temps down as well. Are you using a custom ROM? If you're on Discord you can feel free to message me SCOPE★ BRΞΛD #8460 . I am only offering that so we can get this resolved quickly for you, just copy and paste since I use special characters.

Omgosh, thank you so much for taking the time to respond! Although I'm sure everything you are saying is very smart, I have absolutely no idea what you're saying. I'll do my best to try and answer you. I don't know what SCOPE is or how to send a message there. I don't think I'm using any thing for the "kernal". Also, I don't know what VCC or Discord is. As far as turning off setting for GPS or any other app, the phone will not stay on. I get about 1 sec after the logo when it boots up, then the error message about overheating and it immediately shuts off. I did a factory reset so everything should be good to go as far as apps. I don't think I'm using a custom ROM. The only thing I did was install TWRP, unlocked the bootloader and rooted the phone a year ago but nothing since then. As I stated earlier, this happened right after I did a display repair. Is there something on the MOBO that can get bumped that will make your phone get hot or send a overheating error. My phone doesn't show any sign that there was ever thermal paste on it prior but should I add some now. Will that help?

Update... Now the phone does not power on at all. When I plug it in to charge it I get an error that says "Device temperature is too high or low. Please move to another place to charge. I wonder where you went. I googled SCOPE so I could sign up to message you like you asked me to but nothing but definitions came up. I know I'm out of my league here. You guys all talk so technical. I didn't understand one thing the person asked me for. I know it's rare to get a response as quickly as I did and I was so happy to see someone had responded. Now, I just feel stupid and defeated. I thought this site was inexperienced with cell phones friendly. I'm just trying to get help so I don't have to go out and buy another phone again. Can someone refer me to a site that is more directed toward people who don't know much about the technical side of cell phones... please! Again, thank you for your time.

Hey, I just wanted to say sorry this happened to you. The same thing happened to me. My LG K20 Plus, no matter what button combinations I push and for how long I hold them, will not turn on or go into download mode. Plugging it in to a charger or PC does nothing either. Before it got to this state, I got the infamous green screen of death/Demigod crash handler (google this--it's a known issue with some models of LG phones and it happens when they overheat). It's definitely a hardware/build issue, and especially since this issue keeps the phone from turning on or connecting to a computer, I don't see a workable fix short of buying a new phone, unfortunately. Again, I'm in the same boat so I'm not happy about it either. I would say XDA is by far the best site to find a fix to this sort of problem, so if no one here has any suggestions on how to fix it, I think you (we) may be out of luck.

Thank you for letting me know. I'm not sure of some of what you said but I did catch the bottom line. Basically, just hold onto the phone until someone here comes up with a fix or workaround? I have a question for you. Did your problem start after you did some kind of repair? I'm wondering if I bumped something on the mobo to make it give a false overheating error. Do you happen to know where that sensor might be located? Sorry you are having problems to. It really stinks when your phone breaks and no matter how much time and energy you put it to figuring out the problem to fix it, there just isn't any good answers out there. I wish you lots of luck and if you figure anything out, please update here so I can try it too.

You need a whole new phone.
That or you're gonna have to replace the hardware
