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.

I think my device is broken.

This is just plain annoying.
Already having a bad day as it is - I was playing on Xbox Live when my 360 decided to throw up the red ring of death. In a pretty bad mood, I went upstairs and I tried ringing my dad so I could have someone to yell at and share my problem with (he's out drinking).
Unable to access my dad, I slammed my G1 against my computer desk, when the screen froze in mid-animation between the Dialler and the Home.
I left it, pressed some buttons, stuck. I took the battery out, back in, boot, fail.
My problem is that the screen is just a plain black screen. The screen itself clearly turns on (you can see the screen lights up slightly) but no g1 logo appears.
I'm pretty f**king annoyed at this, so if anyone can offer me some help, I'd appreciate it.
I'm running the 2708+ radio, the 1.3.003d (or whatever, it's the one with a d on the end) hboot, Amon_Ra recovery 1.7 (cyan style) and COS Gingerbread ROM (latest stable).

NO GINGERBREAD ROMS ARE STABLE FOR THE DREAM.....no matter what anybody claims. It is impossible for the dream to run GB stable....the hardware requirments just aren't there...it doesn't matter even if your swap is 16gb the phone can't process the info quick enough to run smoothly. The processor lacks the capacity to read the code quick enough do to the lack of internal memory so we use swap space. But no linux based os can operate efficiently in this manner and will cause all types of force closes. Literally after 10 days of normal use with absolutly no bloat.
Edit...can u boot into recovery or bootloader?

That is just plain incorrect. You incorrectly claim that *smooth* is a requirement for STABLE. It is NOT.

I would suggest that you should look into anger management counselling. That seems to be the root of your problem. If you were in better control of yourself, you wouldn't have smashed your phone and broken it.
Your toy broke, so you wanted to YELL at your father. Failing that, you SMASHED your phone. This isn't looking good on you.
Learn to calm down. A few deep breaths.... relax.
And time to buy a new phone.

bluray players
settop boxes
routers
switches

on and on
wake up man, Linux is very good at almost everything
And GB is running just fine on my G1
in fact I think it runs better than Froyo

not sure I can help with the current problem
but this may be of help going forward

sorry i didn't read everything but im curious if you tried booting in recovery mode? if thats successful than i would try unrooting than starting from scratch and flashing a diff rom.. no better way to be sure han to go back to the beggining lol besides that i've never really heard of that issue.. sorry i cant help more than that i hope you resolve this problem..

[Q] It seems to be a "full brick"

Was updating using Odin when, as my luck always proves out, a circuit breaker tripped and cut power to my PC. The phone seemed to be frozen on the "Download Mode" screen (30+ minutes of zero activity) so I pulled the battery. Upon reinserting the battery I discover that the phone is 100% unresponsive. I've tried every trick google could produce for me with the exception of the "homemade jig" method as it seemed fairly clear that the phone needed some semblance of life for that to be effective.
So, my question is... WTF??? I've soft modded wiis, hard modded xboxes, hacked PSPs flashed hundreds of phones and generally revel in futzing around in this manner of endeavor and have NEVER bricked a device (even after some incredibly stupid mistakes). This just doesn't make sense and I haven't seen sysmptoms such as mine presented in any of my web searches. Any ideas???

I'm not saying your not a modder, but you should know to have a UPS hooked up to your dev box, for me its a laptop, so...
Anyway, try removing the battery for 1m, press power button with batt removed, now start up Odin, plug the phone in (batt removed still) and see if the phone connects. I'm sure someone will pop in here and provide links to several threads that describe different methods to help you fix this, I would but I'm sorta busy...

Keep the battery out for like a half hour and then try again. That has worked for some people.

Or try the mysterious button that may or may not exist. I know I'd be pushing the heck out of it just in case.

Thank you so much for your quick input... I tried precicely that 3-4 times (google search turned it up) and it was a futile endeavor.
And yes, I am fully aware of all the proper precautions to take, unfortunately I am also fully stupid with frightening regularity (well, maybe just lazy and reckless), I seem to have become a tad cocky as I have never really had to face disaster before today.
It won't happen again!

plug phone into computer without battery. Then hold power and 1 to go into download mode (still no battery)
That there is what I've seen as most effective thing to work on bricked phone's.

cool... I just popped out the battery and will let you know the result in about 40 minutes...

this happened to me recently, i found a post with the solution being to pull the battery out of the phone hold down 1 and the power button at the same time before popping the battery back in and it will send you to the proper screen to odin back to what you need, worked perfect for me

oh crap I editted my previous post. i forgot to mention go into download mode...
It's --
Remove battery and plug into computer. then go into download mode WITHOUT Battery still.

there is no hole in the back case of my device. I've had my device powered on and bent the **** out of a paper clip trying to push the 'hidden magic button' to no avail.
YMMV (false hope ??)

Cool, didn't know that little button existed!

I bricked mine the same way a few weeks ago and tried every trick in the book over the course of 2 days. It was truly bricked. I don't have insurance; however, my phone was under warranty. Since I couldn't get the phone to boot or anything I figured there was no real way of telling what went wrong. I sent it in for warranty repair and 10 days later, the phone returned in working order. Work order says they replaced the main board. I marked the phone before returning it so I know its the same phone and it works fine now.
And before anyone says anything, I know, I'm an evil bastard. But I figure it's payback for a samsung flatscreen that died 6 months out of warranty.

I've done this, leaving my battery out for 20 mins or so, and leaving it out while going into download mode worked for me. I don't know why but sometimes I can't even get into download mode with my battery in.

it doesn't..
to prove this (or dis-prove it).. go into clockwork and make a nandroid backup (you know, just in case)...then boot normally and while you're looking at your home screen, jam a paper clip in there as hard as you can. Your device will do nothing.

No, it's just not proven. Some people swear by it, some say it's a myth and some say it depends on when your phone was made.

Theft proofing your phone!

I've had my phone stolen more times than I'd like. Given the fact that I've had my phone stolen this many number of times may suggest to some that I'm careless. Well, that would be a correct assumption to make. However, I don't equate being careless with deserving to have my phone stolen by some low lying piece of koopa. Anyway, the last one was a Moto G and the thing that pissed me off was the fact that the device had achieved an equilibrium in all areas that are important; the right balance of applications, just the right battery time etc. It knew me and I knew it. We were familiar to each other and then it was ripped from my clawing hands, never to return again. At that very moment, I made a decision that never will I let another phone be stolen again (iA). So I decided to make my phone theft-proof, not theft-resistant but theft-proof. The phone in question is the Moto X.
This is how I did it. First you need the following:
- A handset whose battery cannot be removed (at least very easily like the Moto G/Nexus 5/Moto X)
- Root
- Xposed Framework
- Xposed Framework Gravitybox module
- Anti-theft app (the one that I use is cerberus https://play.google.com/store/apps/details?id=com.lsdroid.cerberus&hl=en)
- Bringrr or any other bluetooth perimeter based tracker (optional but recommended)
It's a fairly straight forward procedure. I'll lay it out in steps.
Step 1:
- Buy a phone whose battery cannot be removed
Step 2:
- Root the phone
Step 3:
- Set a pattern or number lock on your phone.
Step 4:
- Install XposedFramework
Step 5:
- Download and install Gravitybox module from within the Xposedframework
Step 6:
Go into the Gravityox module from the app drawer, then go into "Power Tweaks" and then check the "Disable power menu on lockscreen" option. This ensures that when your phone is locked (assumption is that you keep your phone locked or secured), nobody can turn it off or lower the volume. This is crucial when it comes to theft. Usually when a thief steals a phone, the first thing he does is he turns it off or removes the battery or reduces the volume to zero, but if he can't do any of these then the thief has a tracker in his hands and he's in deep ****za.
Step 7:
- Install an anti-theft app. I recommend cerberus. It's very versatile and wholesome. I really like the fact that you can actually make it into a system app which means that even if the thief were to somehow turn off the phone and then turn it on again and crack your pass code or pattern lock and factory reset the phone from the settings, the cerberus app will still be there doing it's job of tracking your phone.
There's only one way of getting around this as far as I can tell but I don't think I'm going to tell you how. That would defeat the purpose of this little guide
Step 8:
- Get a bluetooth location trackr. I like bringrr. It seems to get better reviews than the others one floating out there. It's a bluetooth device that plugs into your car's cig lighter socket and connects to your phone's bluetooth. If you leave your phone in a cafe and come back to the car, the bringrr will warn you or alert you that your phone isn't with you. It also has small little tags which you can put in your wallet and then your wallet and your phone and your car, all can communicate with each other. So, it's a nice preventive measure.

Even if you disable the power menu you can just hold down the power button until it turns off.

True....but that's not true if you havent confirmed it yet.

also if they have a pin they can eject the sim
than hold power til it shuts down
hold down and power get to recovery and wipe the phone
after that if they are really good change the imei and bam
cant track or black list it
i know imei is hard to change but i know it can be done

holding down the power button does turn it off but you gotta keep your finger there for a while. and I'm betting that an opportunistic thief really won't have his wits about him to figure out why the power menu isn't showing up and might freak.
and yes! these are the two flaw in this plan, the removal of the sim. however, if they insert another sim into the phone, cerberus sends a message to the designated numbers. also, imei changing IS hard and can't be done on the fly so there's a window of opportunity between the theft of the phone and the subsequent IMEI change (if there is one) to trace and recover it.
Also wiping the phone won't remove cerberus. you'll have to flash a new rom to get rid of it. so they can change the imei and whatnot but you'll still be able to trace it once they've booted it back up.
however, it'll give you and your phone a fighting chance

Just out of curiosity how many phones have been stolen from you? And how were they stolen? Maybe there's something that you change to not get your phone stolen.

Well the first phone was Iphone. The very first Iphone. It was stolen from my car while I was sitting in it. Happens a lot where I am; Pakistan. I was waiting for the light to turn green at a signal when this guy showed up on the passenger side door, and in what seemed like a flash, opened the door (which unfortunately was not locked), snatched the phone (which was lying on the passenger seat), ran around the car and on to the other side of the road where there was a guy on a bike (who I had not noticed before) revving it. The thief got on to the bike and they were gone. I had in the meanwhile only gotten out of the car and managed to shout out an expletive but it was too late by then. The phone was gone.
Ever since, I keep my car doors locked at all times.
The 2nd phone was also stolen from my car while it was parked in my garage. Probably the driver. It was a Nokia.
The 3rd phone was the Moto G. Went to this cafe to get some ice cream for wife and kid. Rush hour traffic in the cafe. Some seedy types were at the counter as well and I was wearing baggy clothes and got pick pocketed. Didn't feel nothing. Last known location of the phone was the cafe according to Life360.

1. Sucks that people just walk up to cars and steal while you're in the car. But like you said windows and doors locked will help.
2. Sucks that people steal. But assholes work everywhere. But never leave your personal property unattended.
3. Keep your wallet and phone in front pockets its harder to pick pocket. Or wear pants that are not too baggy so that pick pockets cant easily get their hands in.
I'm not sure how crime is in Pakistan but it sounds worse than here in the states. But even if you can track someone, remember its not worth getting seriously hurt or worse over property.

I guess I'd add that another step no matter what theft prevention you have, is to make a backup. Once you find that great balance of perfect apps and configurations, take screen shots of your app drawer at the very least so you know what apps you had installed. Take screenshots of your home screen so you know what icons you had where for that instinctive muscle memory of unlocking and tapping email in the lower right without really looking or thinking about it.
I've never had a phone stolen, but I've bricked and wiped enough times to know that backups are important even if your phone doesn't get stolen.

carry AK47 in front seat of car, problem solved!

Turn in android device manager with location reporting. It will track your phone down for you.

Well, all I know about crime in the States is what I see in tv shows, but yea, it's everywhere. crime and criminals that is.

I prefer keeping my phone by my side at all times....to battery sucking theft solutions.
But to each their own!!
Good info here for sure! ?

In my opinion it's better to leave the phone without a pin because, if i were an average theft who doesn't know that much about phones, I'd just remove the accounts, the Sim card and apps. Maybe I would do a factory reset and with that I'd be happy so cerberus would survive.
Also I'd recommend you to hide cerberus from the drawer and make it only available from the dialer.

Does holding the power button for 8 seconds still turn off the device with the gravity box module disabling power? if someone could force the phone off then turning it off from the lock screen is the least of their worries.

I thought that just rebooted, similar to holding POWER and VOL DOWN for a while to simulate a battery pull on Moto devices.

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
