[HELP] Phone boots up only when cold ?!?!

Hi people,
I have a question, I've been reading these forums a lot but now I have a problem that I don't really understand:
My HTC Trinity that has served me well does not want to boot at normal temeratures 21C - 70F. The akward thing is that if I put it in the freezer for 10 mins, it starts working , doesn't get hot. As it reaches 20+C it freezez or doesn't want to wake up from sleep anymore.
Any ideas as to why this happens it's clearly a hardware fail but what part of it ?
any help would be greatly appreciated.

Maybe it's the battery......did you tried it with other batteries....?

It maybe that you have a poor connection within the phone being affected by thermal expansion. Might also be moisture condensation in your phone (made worse if repeatedly placed in and out of a freezer) that requires drying out.

I'm guessing it's not the battery as when I put it in the freezer I take the battery out. Also, while the phone is off the battery charges normally, without heating up or anything.
The theory of a faulty contact makes more sense but then which one ? I do now have a star shaped screw driver with me (I'm travelling for the moment) but I'll try and open the phone once I get back to a more tinkering friendly environment.
I have put it since in a drawer and it has been waiting for me quietly. In the mean time I bought a Sony Xperia X1 which is an excellent phone. I would still try to fix my trinity, I'd use it exclusively as a GPS if it works.
Any other theories as to why this might happen or what should I do to fix it?
Thanks guys for the useful replies !

When issue occurs will it power up plugged into charger?
As BundyR stated there is a poor connection somewhere. Also known as a "cold solder joint". The trick will be having device apart but still being able to power it up at the same time and start poking around with a toothpick and a magnifying glass starting with the battery contacts and moving on from there.
good day.

INspire goes into car mode by itself

About 2 days a go my Inspire started going into car mode by itself. I figured it was something I did from installing roms so I put everything back to stock and it fixed the problem for a few hours. Then the problem started again.
So I took the phone to ATT and of course it worked fine when I was there. However as soon as I started driving home it started up again. I then plugged my phone into the car charger and it stopped. So now I'm wondering if it's an issue caused by the usb port, or the usb cable that came with the phone from HTC.
Any help would be greatly appreciated.

Do u have ur bluetooth synced to car? If yes, that's a trigger for car mode to pop up. U can disable this in the app settings.

I don't have any bluetooth devices at all.
I should have been more clear I guess. It goes into car mode just sitting in my pocket. or on my desk.

If u don't plan on using it, u can freeze it in tibu, or set it to "disable on boot, keep disabled" options in start up auditor, or rename the apk to bak extension.

I never plan on using it, i'll try that out tonight. First I need to re-root my phone though.

I've been having the same issue, always from my pocket with the screen off. I'm running gingerbeast 1.0 and just figured it was rom related, thinking something else now.

I was running CM7 when it started, so I went back to Leedroid and it kept happening. So I loaded up CoreDroid and still had the same problem. No I'm 100% with s-on and everything and it was still not working until I plugged it into my car charger for some reason.

I ran into this same problem, it would just go into car mode for no reason and when I would get out it would just go back into it. I haven't done anything to the phone since I got it, no rooting or anything like that. But then after I restarted it a couple times and took the battery out it was fine. good luck on getting this fixed

hey guys new to the forum. i just started running into this problem over the last day and a half and signed up to ask about it. I just got this phone a bit under a month ago and havent rooted the phone or downloaded any non market apps.
I planned on taking it to AT&T tomorrow, but was curious if there was a fix i could do before hand.. has anyone found a way to fix the problem for sure?

I did a battery pull on it, and plugged it into my car charger and that fixed it for some reason.

Yep have/had the same deal. Not rom dependent. I deleted the God damn thing I finally got so tired of it happening at the worst times, and all is well in the world since. Kinda a wierd bug. I honestly thought it was something my dumbass was doing, good to see im not alone.

Hi guys, I'm also having the same problem. Tried google search but only thing came up was people complaining when they plug it into a USB cable which understandably will trigger it
Mine however would do it on its own, sometimes when I'm in the middle of something, sometimes it just sit there. I was not rooted when it started happening. After rooting, it's still doing it. I'm still on stock ROM right now but from what you guys said then even if I go to custom ROM it would still be the same issue then
There's a way to disable it from what others posted online, by going into the Navigation app and go to option and turn off automatic car mode. Unfortunately every time I open Navigation, mine will always says your country is not supported (I'm in Kuwait) and switch to google maps and won't let me go to option so I'm kinda screwed

It should be something like car home or car dock.

I don't see anything related to car dock or navigation or anything of the sort on Tibu.

I found it finally. It is called "CarHomeGoogle.apk" under /system/app folder. Try looking for the same on urs too. Maybe look for CarHome.apk if that's not found, and rename it to .bak file.

This happens everytime i use my car charger. Turns out i can use my radio to charch my phone through the USB port so i just switched it over to that.

I had the same problem quite a while ago.
The problem is that the Inspire's mini USB port is not engineered well in a way that the gold pins touch each other in some way, which emulates the way a car charger starts up car mode.
My solution was to clean up the port using an air blower, since dust can arc the two pins together, shorting it.

No luck there or finding the cargoogle.apk in coredroid. Any other ideas?I have a feeling that this is what is causing my screen to come on by itself thus draining my battery.

[Q] No tablet display but HDMI works.

Hi,
Yesterday (08/02/2013) I updated my tf700t, everything seemed to be fine after it rebooted, I was playing a game, the battery was low, and it turned off abruptly. I assumed it automatically shutdown because of the battery, so I put it in the dock and plugged in the charger. Several hours later I tried turning it on and nothing. I held down the power button for 8 seconds felt the double vibration, but no display. I tried various combinations of docked/undocked, power cord plugged in, holding the power button for 30-60 sec. etc. but nothing.
Out of curiosity I connected the HDMI to my computer monitor and sure enough, it was there, I could unlock it and everything seems to be functioning fine, just no display. The digitizer seems to work fine, although guessing where things are at is pretty tough.
I think I tried the cold boot, volume up/down (I tried both) plus power, and it didn't make a difference.
In order to do the update I had to flush the DMC Client and CMClient data and cache, I had been getting errors from DMC Client crashing.
Also I'm not certain this is update related, as the tablet had been acting wierd, which is why I did the update. I would press the power button to turn the screen on and nothing would happen, so I'd hold it down longer and the tablet would reboot and finally the screen would come on, or it would come on a few seconds after I pressed the button. I was getting a lot of reboots etc... I thought the update might resolve this.
I'm not sure if the problem is hardware, firmware, or software related.
I'm wondering if when I flushed the DMC and CM Client cache, maybe I deleted the drivers for the display or something?
My options seem to be:
1.) Factory reset by feeling around the digitizer while connected to HDMI
2.) Factory reset via the pinhole
3.) Install new (old) firmware via usb/computer. (the device is recognized by Windows 7 so I think this is doable.)
4.) Send it off to Asus. (would this be free?)
So my questions are:
1.) is there something else I should try?
2.) what order should I do the above in?
*Note: I'd like to save my data somehow.
*Edit: I forgot to mention I was on 4.2.1, no root or anything. Also I bought this in July of '12 so I'm pretty sure it is out of warranty. Any idea how much it might cost to send it off? Perhaps I could replace the LCD myself? I replaced the digitizer/screen on an ipod touch, although I'm sure this LCD is much more expensive and much harder to replace. This is turning into a nightmare. So much for trying to keep my data, now I hoping to keep this from becomming a paperweight.
Thanks.

A bloke at work had this issue. He let it rundown and left it for 3 days. It worked fine again after that.

If you don't even see the boot logo, it cannot be software related.

Thanks for the replies.
I'll try letting it run down. Would putting it in the freeser be helpful/safe?
I guess on the software/firmware it depends on the definition. To me drivers are software, firmware is anything written in VHDL. I suppose what I'm really wondering is if it is software/firmware vs. hardware, i.e. is the LCD or some other component dead or is the display just not getting written to, initialized or whatever.

I wouldn't put the tablet into the freezer.
Does the backlight come on? If not, it's definitely a hardware problem. If the bootloader boots fine but doesn't show anything, that also looks like a hardware problem.

I'm not sure about the backlight, I think maybe it does, it is kind of hard to tell. I'll try checking in a dark room tonight. Since the screen is just black I suppose I'm looking for a brighter shade of blackness?
The bootloader is definitely booting fine. That is what I meant in my original post, the HDMI out works, I can see everything there, I can even swipe and tap the digitizer and do stuff, it is just difficult to guess where things are at. Do I need to go back and clarify this in my original post?
Do you think this definitely means it is a hardware problem? I figure I'll try letting the battery run all the way down and let it sit a few days and recharge it as sbdags suggested, in the meantime perhaps I should contact Asus, but I'm not lookinf forward to that.

I don't know what is the cause but like I said I saw this with my very own eyes - the same as yours. Double buzz on boot not screen but HDMI worked. Somehow completely draining the battery fixed it ...... So hardware / software? Who knows? If it was hardware why did draining the battery fix it? The device has been absolutely perfect for 3 months since and has never done it again.....

Thanks sbdags, I will definitely try this. I'm not sure if I should hurry and contact Asus though, I bought this thing around July 22 2012 I think so it is barely more than a year old, not sure if they would cut me some slack on the warranty or not.
Do you think I need to let it sit three days or just make sure the battery is good and run down before charging again? Also I've seen some suggestions for charging from a computer vs. wall as it charges slower, do you think that would be better?
I'm getting into panic mode and want to make sure I don't do anything rash that limits my options.

All he did was leave it for 3 days. Our assumption was that the battery had completely drained in that time....... A charge later (he was actually just about to box it to send to Asus) and it surprisingly started as if nothing had happened.

Having the same problem
I am having almost the same problem, except that the tablet screen works when the wall charger is plugged in. THe HDMI display and the digitizer work fine. It is just the tablet's screen dispaly when the charger is unplugged.

So I didn't have any luck letting it run all the way down.
I contacted customer support, the warranty is only 1 year, but fortunately for this there is an extra 3 months, so I just managed to squeak by, although I'm keeping my fingers crossed.

same problem as you both
i have d same problem well until last week the screen displays when conne ted to wall charger now its all blank but iy works via hdmi, digitizer works fine but all blank, this tf201, does anyone know if i change d whole display it will work?
i already bought the tf701
any suggestions is welcomed and did you get youra to work?

I have not seen people mentioning VHDL and verilog for a while, hahaha... It sounds like you are a low level or physical layer programmer. Any way, a firmware is in general a low level program that communicating with the hardware and the software or high level program ( level 7).. If you will, a firmware is a management levels (level 2 and 3). A VHDL is a level 1 which generates a 0's and 1's or mapping the transistors in the FPGA chip for example.... Oh well, it is just my definition...

If you can get the output from the HDMI port, it is more likely you have a hardware problems. I think that the problems are your display related hardware. If you really want to troubleshoot your issues, you can look on the mother board to locate all the electrolytic caps and check to see any abnormal signs of those capacitors. Those caps are the one that will blew up first before any others parts go....Good luck...:fingers-crossed:

[Q] Tablet shutdown just after boot.

Hello, I've registered especially for that problem, so what happens is after I get the cool NVIDIA bootscreen, I instantly come up with a message saying "Turn off" or some kind of shutdown message.
Before you ask, yes, my bootloader is unlocked, and it was rooted until I do a factory reset, since it was doing this auto shutdown, I also currently have CWM Recovery, which is quite a nice recovery !
Here's a list of things I tried and that didn't do anything:
Try to cancel the shutdown somehow
Booting the tablet multiple times
Factory Reset
Also, I can't seem to use it with my computer since, well, that damn shutdown on startup.
So what can I do ? I still have access to the recovery. Could it work to give it some ADB in the tablet's face ? I really need this beautiful piece of hardware to play vidyagames.
And also, the battery is full, and working properly (I can kind of see the battery on top, it's probably at 80% or something.)
I'd also like to point out that it suddenly started doing that. And there's also a SD card in it. And also, when I access the fastboot, well, I can hear it on my computer, guess it's a good sign !
And yes, it's the one with Wi-Fi, so if I have to use a ROM, I don't think I would have much choice. Also Android version is Lollipop.
EDIT: Nevermind for the ADB, it requires my tablet to be on, at least I can still use CWM Recovery and fastboot ! yay
EDIT 2: The message is:
Power Off
Shutting Down...

I have the same problem. I've tried flashing the recovery 2.1 files, sideloaded the 2.2 ota, etc. The last thing i'm going to try is wiping the system with trwp then installing the 2.1 recovery again.
-that did not work. I have initiated the RMA process.

Anyone has some instruction how to safely open a NVIDIA Shield Tablet ? I woud love to check if some hardware went off so I can rebuild it.
EDIT: Wait, it can't be hardware... It just can't ! Why ? Well... simply because right now i'm in TWRP recovery, everything is working exept... oh wait... CPU temperature is going crazy. 429491929 C... yep... I don't think that's right.

Ok, sorry for the double post, I know it's really bad... BUT I THINK I KNOW WHY !
Bad thing, it's the CPU thermometer, it has gone crazy.
So, I installed you know, that TWRP recovery, and I checked the CPU temperature.
Wanna know what it is ? It's hotter than plasma, or lava, or anything. Heck even the big bang.
CPU: 429491899 C.
That's right, that much, so... any idea how to fix the CPU Thermometer ? I knew it was something with the hardware. My theory is that it is not connect properly to the CPU. Since everything on TWRP is working... TOO FAST COOL! like all the apps I had on that tablet.
So here, problem half-solved. The tablet shuts down because of the CPU temperature, to prevent it from overheat !
EDIT: Finally fixed it ! ;v; Like I said, it was the CPU Temperature, since it kinda fell off my bed now that I remember, what is the CPU thermometer ? Well, it's a small bar near your stylus slot. Inside the thing, also, when you insert you stylus you insert it directly into the hardware part, next to that CPU Temperature thing, maybe that caused it, but well, basically, I opened my tablet with a cool little trick, basically, I took the back of my stylus and I forced softly on the tablet in the stylus slot. And what happened ? It opened a little ! So, what I did is slowy remove the plastic around to to not cause any crack of damage and it worked perfectly ! I saw that little CPU thermometer going off and what I did is basically push it back into where it was ! Also, the wi fi antenna is next to the camera, it's pretty small for your information ! But yeah, I putted back the plastic case after that and booted my tablet... and IT WORKED!!! It booted perfectly ! So: It was not the ROM or the OTA, it was the auto shutdown to prevent overheat. Also, it seems like recovery mode and fastboot don't care about temperature... so they won't be shutting down ! I'd like to thank the creators of that TWRP Recovery, it's the thing that helped me find out that it was the CPU Temperature ! It's also the first time of my life I touched to some hardware. And i'm really proud of myself even for such a small thing ! Hope it helps someone in the futur ! Thanks for trying to help me !

Well, I would have taken a picture, but I have nothing to capture pictures with... so.. yeah. Else I would have taken photos, it's pretty safe to open it by the way.

If the "bar" you're referring to is the one just off center on the right side, then that's where a Sim card is installed on the LTE model...

If the "bar" you're referring to is the one just off center on the right side, then that's where a Sim card is installed on the LTE model...

Nope, it's a sort of small bar near the camera, just on the top of it, it's made of some steel I think !

2 questions
I'm having the same problem. I already have opened the cover based on how you described it.
1. I can't find the thermometer and what kind of fix should I do with it?
2. How did you install TWRP when the device couldn't even boot properly.
Thanks

I blindedly pushed some components back (dangerous) and decided to put back the cover. I rebooted and yeah, it booted properly! However,after a few minutes it auto shut down again. So I guess the theory that it's about the CPu thermometer might be true.
The question is, where is it really located and what should be it's position? Thanks.

Finally Fixed!
After several sessions of tinkering the unknown components of the hardware, I finally decided to take it to the next level. So I carefully removed the electrical tape covering the perimeter of the battery. Lo and behold - there's a white wire that is loose and I've determined its correct connection through its length.
Since I didnt have a soldering iron and I'm too afraid to use it should I have one, I used brute force connection via electric tape. I peeled more skin to secure conductivity.
Apparently, it's the connection to the CPu thermometer. When it is unlinked, it should register as weirdly high value, triggering hard reset. During the boot up and initialization, the firmware takes note of the value. After studying the behaviour of the problem, apparently the firmware in the chip also occasionally checks the temperature esp when an app is launched. This explained why I couldn't boot at the beginning or if ever boot was successful, antutu causes shut down. So as a solution, I made sure the contact between that freaking white wire and the solder placement on the board MUST be secure.
I'm using my fixed shield tablet to post here Btw. Apparently it has become faster. Antutu is 55,000. But charging the battery seems slow. I must have accidentally messed up something with the battery.
Boy I love my Shield tablet!

Thanks many many times!!
It fall down of the carpet and later that evening I noticed that it s off.
thanks the happenstance that TWRP shows the CPU Temperature it was fast located.
so I was able to search for.. and finally xda did it again..
Thanks all of you

Same problem
Well, my tablet got the same problem
Here some pictures, can you tell me where is the temeprature sensor?

Faced the same problem and I fixed it as suggested by soldiering the white wire behind the tape. Look at the picture to know where it is located.
First attachment with the tape on. Second image with the tape off and after soldiering the white wire to the board. I hope that helps.

wow ... excellent post. this also solved my restart problem. thank you very much.
interesting side-fact: this only affected stock images. all alternative roms (bliss, etc. ...) started fine ...

I've got this exact problem as well but even after soldering this white wire, it keeps shutting down..
Edit: after some more attempts, I got a new temp: 92c. But I still got shut downs.. So I managed to switch it back to that weird 42516516161 etc temperature and now it wont turn off with the Custom Rom Bliss Pop.

I had the same issue. The device started to shut down by itself, sometimes right after boot. Luckily I stumbled to this thread while googling for the issue. Then I verified the problem by installing cpu-z and watching the temperature while waiting for the device to power off. Indeed, just before powering off the sensor jumped to -46 C. So with your help I found the culprit and soldered it back. No shutdowns ever since!

Nexus 5 water damage - screen's all black - motherboard related?

Hello guys,**
Well few days ago I accidentally dropped my Nexus 5 in a glass of water for just 1 sec. So I immediately switched it off and wait a bit to let dry then restarted it, and all seemed to work fine. But just some days later and up to now the phone boots up all fine as usual to the lock screen, and from there I can pull down the notification bar (and navigate through it, activate/deactivate wifi, etc..) but when I unlock it to get to the home screen it becomes all back and nothing appears on the screen even though the phone is still on.*
It's really confusing and weird. When I call the phone it rings (so no signal or sound problem) but I can't still access the screen to take the call as it's all back and unresponsive.
Following some suggestions I disassembled the phone and cleaned it dry but same results again! So now I think the problem is somehow related to the motherboard, coz as you might notice on some of the pictures attached, it seems that some plastic parts have melt down to cover other smaller parts. Anyway guys,*I'm just wondering if some of you guys had experienced something like that and if you were luckier*to find a solution or any directives that could help. Or you even think that's a motherboard problem like, do you know any ways to fix that o buy a new one somewhere??
PLEASE!!

Sorry apparently, I can't publish links until I get like 10 posts or plus..
But anyway guys, I'd really appreciate your help.

Why did you power it on and short circuit it on purpose for??

Bump

@SekouCheikh

Maybe it's a coincidence that you dropped it in water and this happened a few days later. Once in a blue moon mine does something similar to this (although not usually as start up only after lots of use), but I think it's related to an app or xposed. I only notice it after installing a bunch of crap again. Maybe try a factory reset (do it though the computer) just to see if it is somehow not hardware related? That's what I would try first.

Help please

Wait... Are you seriously posting from 2 different accounts??

First, simply try to factory reset or flash a new rom. There is not enough evidence to be sure it's a hardware problem, it could just as well be a coincidence that it started happening just now.
