HD2 Heat causing freeze on soft reset

yesterday i had the problem lots of HD2 owner faced it, my device worked fine, but when i had to soft reset it, it always freezes on the white screen, and never starts up, every many times of taking the battery out, and start again, it finally started up.
i tried to soft reset it again and faced the same problem
i tried to flash the ROM again, but after many tries, i finally got it to flash, but the thing is that the problem wasn't solved, and the unit kept freezing in the start up, but once it started up it worked perfectly until the next soft reset.
but then i tried cooling the device against an AC, and the surprise was that the unis was able to start normally, every time with no problems when it was cooled
any one faced such problem with the device? i will try it again today at noon, when the temperatures are high.

I tried it again now, when the Battery temperature was 38.5, the devise did not start, when i cooled it down, it did start, and when it started the battery temperature was 35.5
can some one with the same issue confirm?

Yes I am having the same problem!
My fone did the same again last night and I'm going to try reflash it today - else the POS is going back to the shop! Not happy!

did you try cooling it down? flashing the ROM did not help me at all

Can this be a Battery problem? that the battery can not provide the required current when it's heated?

ok, i did these two experiments
1- i heated the battery alone on a air heater to almost 45 degree
and cooled the phone, but the phone did boot up normally
2- i heated the phone on the heater and cooled the battery, the phone didn't bootup
so the problem is defiantly with the phone not the battery :-(

Yes, onlywhen the phone was cool to the touch again did it boot correctly. However last night it did the same but would not reboot after leaving it for a while. I tried to do a hard reset but the phone hung on the HTC boot screen and would not go further.
This morning the OS booted but was totally corrupt - it looked like booting in to windows 98!! no graphics, no HTC Sense, no usual colour scheme and a whole whole of corrupt file messages. This happened each time I hard reset - and the USB port also failed to recognise any device. I think it's safe to say it is practically bircked and thus, Ireturned it to O2 today to sort out and give me a new handset! I think it is a hardware issue. Infact, I'll put biscuits on it being that vs software.

it is definitely a hardware issue, but the thing is, these are the first few days of summer in my country, the days when the weather is getting really hot, and i guess this is the first summer HD2 will experience, since it was released in the Autumn, so my guess is more and more units will get this issue as the weather get hotter in other countries

Hi guys.
Weird issue you are facing!.. Mine gets very hot on hard use.. today I tried a soft reset while it was hot and it started normally.
When did you bought your HD2?

i got it like 4 months ago, but i am sure now that there is a hardware issue

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

i know sucj hardware issues are unfixable, i am wondering should i get me a new HD2 or another phone

I got mine on contract in March - 1.48 ROM. but also had the issues in 1.66 prior to sending back.
Just awaiting for it to be returned - I'll report back to let you know if sending it away has fixed the issue. I'll be a mite miffed if they just flash the ROM and send it back lol!

had the same issue: overheating / reset loop / stuck on white screen
contacted HTC, sent for repair, received with new mainboard,
now works flawlessly

how hot is summer in Syria btw?

I had the same problem with mine on an UK O2 network. They took it back and flashed it. Sadly that didn't solve the problem. So I sent it back again and they replaced it with a newer model. This seems to have fixed it. Sadly looks like the early ones were crapy and had the same fault.
However mine still gets ruddy hot when connected to the anything in the car.
Bad job HTC :-(

Hi all,
Actually, there is CPU's overheating problem, not battery's. ALLMOST same problem you'll have if you'll remove cooler from your PC's CPU
My LEO shuts down at 38 deg. and cannot start again without cooling. Definitely, it's a price for 1 GHz processor - it should have less power demand or good cooling system.

Hi had the same problem mine also used to reboot on it's own when connected on pc and overheated. Going to contact HTC repair and send it back. I was wondering though is it ok if i send it back with a cooked rom and 2.10 radio or will they not change it cause i've switched that on my own? Any ideas pls?

Early model as in what date.month.year?
Regarding getting ruddy hot when connected to the anything in the car, it's the connector, IMHO.

I have problems too. My God, today is the first and really hotest day of the year in Germany.When I will back in Spain at 40 degrees celsius there my hd2 will be a bomb!!
My device is a German o2 hd2...

Galaxy S2 refuses to charge and start

Hi folks,
So here's the deal: my Samsung Galaxy S2 suddenly refused to charge and became very hot. I turned it off, took out the battery and it won't accept any new juice.
After I turned it off, it won't even start. So I have a battery that cannot be charged, and a Galaxy S2 that refuses to start. When connected, a battery icon with a triangle is displayed. Any ideas?
Should I try to get a new battery or is there any trick for this? I'd rather not send it away.
Cheers

It's pretty similar to this issue:
http://forum.xda-developers.com/showthread.php?t=1114016

No one knows, huh? That doesn't bode well...

This is identical to my problem. To restart your phone. Take the battery out. Plug the phone in, wait a few seconds then put the battery back in. Imediately, press and hold the power button. The usb charging circuit is damaged. It needs a repair but will probably be replaced. A few of us had this problem.

Thanks for your reply! If that's the case, it's the first phone I've ever had since 1998 that has broken down.
I tried the method of starting it that you suggested, but it didn't work. I guess I have to send it back. Even though it's a great phone in other regards, I won't be buying a Samsung again.

Hm, it suddenly decided to start again for some reason and now I can charge the device while it's turned off. But when I try to charge it when it's turned on, it just becomes super hot and loses power instead of gaining it.
Can it be a software issue? It's really weird, since my SGS2 can be charged while it's turned off but not when booted.
Cheers

Hi there i have the same problem with mine too, do you flash any rom in it or kernel?
I guess its a problem with the kernel or rom you have flashed, mine have the same problem, but you can put it charging in the usb cable in the computer and let it stay there for a whyle, then you have to try to boot it up by using the 3 keys (power+home+vol up) it will boot in recovery mode then you ask it to reeboot and install an updated kernel or reflash the rom, while the device is on, do not put it off, because if you do it you will have the same problem to put it on again, but when its on it charges normally.
I have changed mine for a new one but the problem i am sure it was the things i flashed it. I was using another kernel to install and root the device and again put the original stock kernel in the device to get rid of the yellow triangle, but that came up with that problem. I even dowloaded root explorer in order to reset the battery status bin (you have to be rooted to do this) and reboot the phone but with no avail. The other you have to do this is install CWM MANAGER V1.80 MY KERNEL CF-ROOT 4.0 MY ANDROID VERSION 2.3.3 BASEBAND i9100UHKE2 and now note this the stock kernel was the uhke4 but the kernel i put it it is [email protected]#2 COMPILATION NUMBER: GINGERBREAD.UHKE4
Note: i dont know if it will work for you, i am using a stock rom from samsung. If you do not flash anything its better to return the device or even you have flashed it buy a usb jig and reset the counter and find for the repair, they have to fix that for you.
I hope that have provided you some help.
best regards

Happend to me after installing an over clock thing i uninstalled it and it worked fine

thats what i have said but try to update the kernel and try it mine was uhke4 and now im using xwke7 rooted and worked like a charm all working perfect now, just the problem with the yellow triangle on boot, besides that nothing else even it improved battery life and gps works even better .
hope i have been usefull.

@OP- Go to Service center. Don't waste your time by doing this and that. I am having the same problem, though freak me did some experiment with it. You will get replacement/repaired as it's inside warranty very much.
And don't try any freak method with the new one.
Regards.

Man, better sending your phone to service center before damaging it more.

Have you got the replacement?????????????

Thanks for all the replies. Like I mentioned earlier, I'd rather not send my Galaxy S2 away to a service center, even though there obviously is something wrong with it. I'd be without it for weeks and my S2 is like the Ring for Gollum
I can still charge it now when the device is turned off. But whenever I try to charge it while it's turned on, it just becomes super hot and loses power. I'm starting to think that the battery is damaged, and not the actual device.
Anyway, I just rooted it... Couldn't resist, so I bet I can't even send it for service now without trying to unroot the bugger

so if we take it that anything thats not needed is a waste of time ? like being here ? well, that first line about service center just make me think . Why would the OP post here, because he's not going to a service center..looks like it. it could have been he would though. I just dont like that advice myself. here, they wouldn't do nuttin for me if i brought the phone.
I knew a few that a few years back had phones for repair, they don't replace them, they do some awful repair, and it doesnt work afterwards. second, if after using a phone a whole lot I wouldn't trust them providers with it for weeks . What I mean is for some, its like sending a diary for inspection and approval. Not being VIP nor secret, but ya pwn biznizis ya pwn bizniz.
there must be something to it with the software/firmware, as mentioned a bit below

well, I tried cyanogenmod, and whatever kernel/modem/baseband etc... so! it is like version ki8+ki4+ki3 if that makes any sense . brand new sgs2 gt-i9100 int. version in white. battery ran down to 6%, microUSB thru PC or charger didnt do nuttin, then i turned it off, and looks like its charing. must be a BUG!!
gotta fix that. or get a bigger battery..and then fix that
any1 else having problems with cyanogenmod ? probably im running a wrong kernel, or a wrong 'something'.
does cf-root conflict with rom manager, if so, what to do anyway ? what rom/kernel version should one use with cyanogenmod 7.1.0 RC1 ? how many 'roms' are prone for this no-charge-issue ? time for another rom maybe? cm7rc1 report version 2.3.7
I can also confirm that the phone does get a little warmer during the no-charge-issue. Would want to get one of those colored alu covers, but not sure it would do much better in coming cold winter.
whatever is causing the issue, thats really stupid! what kind of problem to have..put that on the messenger machine 'my phone has gone off to charging at the moment, it'll be back later'.
questions is - what to flash ?

My Samsung Galaxy S stopped responding so had a replacement sent over - Orange replaced it with a S2 - however I struggled with it for hours before ordering a second replacement - charged on first go then wouldn't charge again - so again fiddled about for ages. Eventually took SD card out and now it works fine bloody annoying.

2 phone in 2 weeks the yellow triangle
The first SGS2 I got the second time I went to charge it the Yellow Triangle with the Astrix symbol came up with in 2 weeks the batter was over heating and only holding a charge for 4 hours. I exchanged for a new SGS2 and it has been 3 days the same Yellow Triangle with astrix has come up. I am going to get my money back and use my old phone which is unfortunate cause I really like the SGS2. What is the issue with this? is this really a connection issue?

Take the phone back and get a replacement as it a very good handset.

Samsung Say's
This Yellow Triangle with the exclamation point in it is suppose to show up when the battery is completely dead and only when completely dead until the phone has enough juice to be turned on then it goes away. It should not be related to any other problem with the phone. If you get the yellow triangle when you still have power to the phone then you need to take it in. This will lead to over heating the battery and trust me the phone gets extremely hot. Then you will not be able to charge the phone.
If the battery is hot take it in.
If the Yellow triangle only shows up when the battery in completely dead and then goes away a little after you charge it your phone is fine.
This is what Samsung and it's tech support said to me.

Dead Nexus S

Hi guys,
Tried searching for my problem, but though I found some similar stuff, noone had quite my problem.
I was checking my Nexus S after a trip and it was with the 'emergency only' message. This sometimes happens to me, not sure if it's due to the roaming activation or caused by a bug where the radio subsystem crashes after a long period without network.
Anyway, I proceeded to my common solution: Turn off and reboot.
Except that after the phone was off, it would not turn on.
It doesn't even vibrate. It doesn't show anything when connected to the wall socket or to the computer. It's just completely dead.
Now, I'm not even sure if this is a hardware or software problem. Any idea on how I can debug this?
Here's what I've tried:
1. Take the battery out: no changes (even tried leaving it out overnight).
2. Charge the phone overnight: no change.
Next step: I'll go to a store and try a different battery... meanwhile I'm without my primary phone which sucks... Can anyone help?
Thanks in advance!

Try booting your phone into the bootloader. Hold the power button and volume up button simultaneously.

If it is not the battery, i can see what else you can do, a "dont turn on" phone is a dead end...

Guess I'm screwed... I had some pics and other data there... anyway I can get it back? i.e. is there a way to remove the internal sd card?

Yup, it was one of the first things I tried. No sign of life... I can't get a single sign that the phone is even being powered. It's like the battery was taken out.

Sounds like something is wrong with the hardware then. Have you brought it the store? Might need to get a new one on warranty.
I have the same issue with my old Blackberry 9000. It worked fine up until I stopped using it. Left it in a drawer for a few months. Went to sell it to Sprint. Wouldn't turn on. No LED, no nothing. Worked fine months before when I was still using it. To this day I have no idea what's wrong with it and it doesn't turn on.

Why not get an external battery charger and charge the battery up and then test it?

All true, and after trying with a new battery I'll have a bit more information.
But what strikes me as odd is that I didn't leave it in a drawer - I didn't even let the battery run down... it was just a damn reboot! I shut it down, and then couldn't power it up again (try and imagine THAT happening to you). It would be odd for the battery to be sucked dry all of a sudden...
I have a feeling that there's something else... maybe while shutting down something burned out in the power circuitry....? =S
No one ever heard of anything like what I'm experiencing? It sucks to be the only one!
Thanks for all the help so far, guys!

If you can get to download mode nothing is lost. Just flash new image via Odin.

Never heard of that happening, but it's a possibility... Still, I would first attribute it to a bad battery and try that first
Sent from my Nexus S 4G

With a new battery (that works on another nexus S) still no luck. =(
I still can't find anyone with this problem. I feel like the unluckiest idiot on Earth.
I assume I can't get to download mode since I can't even get the phone to report it is charging (it used to do that even if off). Do you want me to try anything, though? I'm open to suggestions until Monday. Then I'm taking it to Samsung. Hope they can recover my pictures.
BTW, my receipt doesn't have the IMEI and a customer service rep told me I need it on the receipt or they won't give me free support. How can I get it with the phone off?
Regards and thanks to all who responded,

nuno, if you cant power on even with a new charged battery, then it's a harware fault and nothing can me done... =o\

I've got the same problem: dead nexus s after a reboot. It says "no service" emergency call does not work. I tried pretty much everything like switching the battery, recovery mode, plug it in, etc. I even updated its image to the latest I've got access to. No luck. I'm already contacting samsung to get it replaced.

Did you try flashing a different rom? Or radio/

I haven't experienced this myself but I'm very interested on what happened. Did you guys flash any custom ROMS? or Radios for that matter?

This looks very similar to what i have. I just got my nexus s GT-i9023, it doesn't boot into fast boot, recovery, download mode or normal. The most activity i have got so fare is when i take the battery out, put it back it, and try turn the phone on it will sometimes flash then do nothing. I have looked every ware. When i use "./platform-tools/adb get-state" it returns "unknown". Any help would be great.
What i think i did was this:
- Unlocked bootloader, this worked
- restart
- installed clockwork mod with fast boot, this worked
- wiped data
- wiped cache (correct me if i spelt that wrong, or anything else)
- flashed cyanogenmod, this got an error but i didn't notice it the first time and i can't remember what it was.
- flashed gapps, this didn't work, when i restarted the phone it said that the installer for gaps had quit.
- restarted
- flashed cyanogenmod again, this is when i noticed the error
- restarted, didn't change anything
- wiped data
- wiped cache
- flashed i9020t recovery, this http://forum.xda-developers.com/showthread.php?t=1061855 i think this is what stuffed it up because my phone is i9023
- wiped data after flashing, thats what it said to do, i thought it was strange but i went along with it.
- wiped cache
- reboot
- now doesnt work.

Take it to the store where you purchased and claim ignorance!

A3000 won't start or flash

This morning my A3000 started up then it shut down. Now when connected to a charger it only shows the LCD backlight no other operation. Tried to flash it but it won't stay on for more than 3 seconds, my XP laptop sees it then it disappears . Tried the reset button, tried disconnecting the battery for 10 minutes, next step is the hammer unless you can help it :fingers-crossed: only joking I would be lost without my A3000.

I know it's really annoying in such posts to say "Same problem here"..
but there is nothing I can do about it, I really have the same problem...! :S
even more, ! don't have an NVram backup so I lost my chance for formatting..

Hi, I had an idea, I have checked the battery voltage which is reading 3.03v (should be 3.7v) and has very low current so I have ordered a new battery today. I am hoping it is just that it can't start due to lack of power.

That will most likely work, I think mine would even be lower than that. but isn't there a way to charge it to that level?

Try to uninstall with wipe (ccleaner etc)+reboot & reinstall your driver from ur computer without connecting ur tab.
Then run spflashtool by download or upgrade mode (anyway which work) for a minute wait time.
The proper quick drivers & latest stock rom can be found at @azam436 thread on page 1-4, check it out.
If u ever flash stock rom by spflashtool, your nvram should be automatically backed up & will restored (cmiimw). Good luck.

All that has been tried of course, we are hardcore users
I tend to believe in @RayA3000 theory, waiting for his follow up about changing the battery, giving that my battery has gone really weak before the accident that I need to charge two times a day or just leave it connected to charger so I can be ready to go any time..

EUREKA - my new battery arrived today and my A3000 started up as usual, I'm chuffed
I have worked with batteries for years (we do camera repairs) and have found some batteries can just loose the will to live, no current. At £17.00 it was a cheap fix.

I have worked with batteries for years (we do camera repairs) and have found some batteries can just loose the will to live, no current. At £17.00 it was a cheap fix.

Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"

Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"
Its a Note 4 SM-N910F, Android 6.0.1, BB N910FXXU1DPE2, kernel 3.10.40-7733605 [email protected] #1
i feel I have tried everything... History:
Phone has been working fine for a year, upgraded to 6.0.1 no problems about 2 or 3 months ago. no new apps installed. Last week it started getting very laggy, keyboard strokes took for ever to register. I thought, ok, time to to a factory reset to blow out any old cobwebs. Did it via the menu. However the phone froze midway thought. I left it for an hour and then pulled out the battery. I popped it back in and it performed the reset without me having to press anything. Cool, thats good I thought.
Now I was going to change the battery, so I powered off as normal and put my other 2 week old original samsung battery in, and it would not power on. After a few reinsertions it powered back on. I though i have to do another reset. So I tried, and it would not reset. It just died. I cant restart the phone, it dies. If I shut it down normally. it wont turn on back on, I have to take out and reinsert the battery multiple times, holding down the powerbutton between to discharge. this can take up to 10 tries now. Sometimes it will go th the unable to bot in normal mode and "downloading , do not turn of target, but it will stay there for ever, more than an hour.
Every 15-20 tries it would turn on, let me get in via pin, only to start freezing up within a min, and then die again. Somewhere I read that a guy hada similar problem, and he used wakelock and that worked, on level 4. I managed to download that and used it, and hey presto, it works!
Now I had to power down the phone for a reason, and it took me about 30 min of battery and powerbuttonholding before it managed to boot up, and I was quick enough to start wakelock on level 4.
It wont boot in to safe mode, it wont boot in to recovery mode, it wont boot in to the factory reset mode. Its the same with either battery, and different cables.
Any ideas what i can do here, or what could be wrong? I havent gotten it wet or banged it.

I am having the same exact issue on a N910A. Phone was functioning correctly and in December it started getting really laggy. Performed various resets, purchased new battery. Still laggy. Up until two weeks ago the phone was slow but now it will not power on . The phone will not charge as well.

Mine did same, 6 months old, not rooted stock firmware. Locked up yesterday, couldn't do anything. Pulled battery and restarted. Samsung logo comes on screen goes black for android boot then it hangs with blue led flashing. Nothing I do gets it past that point. Tried safe boot but it doesn't fully launch with correct button combo and volume up. In the end I re-installed firmware using Keis. All went well, everything as per youtube tutorial. Except one thing, at end of download phone didn't re-start. Still can't get it to boot, any ideas?
Edit: Lock up didn't coincide with any new apps being loaded or updates of existing. Only change was a week ago which was an automatic update of the stock firmware (Lollipop)

are you still under warranty? i sent mine to a samsung center, the guy recognized the problem as the motherboard, said I wasnt the first. That was 3 weeks ago, they are STILL waiting for the parts. They say the Samsung factory are way behind with repair parts, etc etc. I am hoping it will go under warranty. Ill update when I know!

I've been having the same problem that started yesterday morning. I've tried a few different solutions but nothings worked, I get the feeling that my phone is dead and I'm not in warranty either. I'm going to approach Samsung but my guess is they will want more than the phone is worth to repair it. I've read about so many people having the same issues, its horrendous engineering on Samsungs part considering how much their phones cost to start with

Your guess is probably correct and I totally agree with you. I seriously think manufacturers do not want their devices to be problem free for more than two years. Probably why they have stopped making phones with batteries that simply pop out.

Definitely...surely it couldn't have been that hard to make a device with a battery that was still removable on the newer phones. It's frightening how many forum posts I've found with people having their phones just brick out of nowhere (and that's just the note 4). I've given up trying to fix mine, I've tried every method I could find and nothings worked. I can only assume that this problem is simply the motherboard of the phone not working anymore. I'm not even sure what phone to buy now but it certainly won't be a Samsung.

If you do not care about the camera thera are a lot of rather affordable options which can be tossed in the bin when they start malfunctioning and if their warranty has run out. If you care about the camera being as good as the Note 4's than the range of phones you can buy is quite limited.

If you are able to boot it into Download Mode then you should Download Stock Rom file for Galaxy Note 4 from Sammobile and Flash it through Odin..
Everything will be OK... ?

Unfortunately, SAMMOBILE does not have the SM-N910A firmware.

I think the camera on the note 4 is absolutley terrible. I might even go so far as to say the pictures are unusable. the applied noise reduction renders everything splotchy, colors are off and its not sharp at all. and Im not talking dark conditions here.
Anyway, my phone was repaired under warranty and is back to working as it should. It was indeed the motherboard, so if you have the same troubles I had, those are your best bets.

I don't think replacement via warranty will be available. I will attempt to power into download mode and verify if I can get it back up and running. If not, a good ole paperweight.

Sounds like the problems I have: with my first N910F: started with lagging apps / freezing, then random reboots now and then, eventually giving error messages when booting. Finally, now it will only start after the battery has been out for at least 30 minutes, but hangs on error message. When pulling battery out and putting back in it, wont give a single sign of life. Since I was just out of warranty it has been lying around, and I bought a second hand N910F for replacement, sadly its starting to give the same errors too and is just out of warranty too (its currently still working, but with freezes / reboots / and already a event with boot error).
I read It could be memory chips or some power chip on the motherboard, appears to be a common problem. So.... Last month I bought a new motherboard on ebay (chinese delivery, 80€). Received it last week and put it back in; phone is back to life. (putting it in is a very simple task, with iFixit teardown / guide)
Anyway, I love the Note 4 for performance / size / looks, and have been Samsung fan for a while, but this recent breakdowns and information that it is fairly common, has diminished being a fan fairly quickly and I guess the Note 4 will be the last Samsung device for a while after this new motherboard breaks down as well

My phone is also random Rebooting
It also shuts down at 25% of battery remaining, Have you also faced similar issue?

Download the app "Wake Lock" and run the Partial Wake Lock option. Apparently the updated software impacts the CPU. For the restarting issue, put it in the freezer for a couple minutes. You may have to take the battery out once, but it has worked for me every time.

This looks very much like the issue reported here:
https://forum.xda-developers.com/no...-error-fix-t3434335/post72944466#post72944466
There are temporary fixes (wakelock), but ultimately this is a harware issue, and the fix is a new motherboard.
I think that underlying it is a problem with heat affecting the eMMC chip or its connection to the motherboard.

Hey can u pls get me the stock firmware for n910gddu1dpb4

You might find this interesting. Since I couldn't get mine to power up at all, I called Samsung tech and they quoted me $75 to fix it and they would pay for shipping. I figured it was better then getting another phone off Swappa. 2-3 weeks later i get an email that they are repairing it under warranty at no cost to me. I got a refurbished phone since i know my IEMI number was different. they didn't explain why. Anyway, I got lucky i guess.
