HELP! My phone gets hot and restarts! Please look for more info inside!

Hello dear friends!
HTC let me down Kind of stupid phones indeed at least desire...
I have my phone for quite a time now, it is rooted with unrewoked, clockwork recovery and s-on. I flashed many different roms in the past and everything was brilliant. In a pas half-a-year or so I stayed with only one ROM - MIUI-Au. I kept updating it to the newer versions and so on and on. Never had any random reboot or something. At least maybe it was because of some strange app or something else. But now it started to reboot randomly and constantly!
Phone gets hot abit and it just reboots, and never comes to android homescreen again, until I put out the battery, hold it for few minutes, pop it back and then it boots. But as soon as start to play music, or run a game the phone gets hot abit and reboots again. and so on and on. I thought maybe it was a miui issue. So I tried to flash different roms, but guess what? None of the even boot! The main screen shows and with the same second it bootloops again and forever!... (
Even from recovery it sometimes reboots randomly. So i managed somehow to flash my miui back and it at least boots. But it is very unstable now, I barely can use my phone now
PLEASE WHO CAN HELP ME????
My warranty probably out of date, and my phone is rooted, I dont think HTC would accept it...
any thoughts? friends?

What have you set the CPU max to?

Thank you for response! Appreciate, really!! I didn't set it, I left everything by default I think! Because as i said, i even tried flashing different roms, not only miui.
What else could be? By the way, with stock froyo rom If I remember correctly, sometimes it became extremely hot, but I didnt get any reboots from that. But now, it gets just a little bit hot and it seems that this causes the reboot...

Now what I just noticed, I get reboots even when the phone is idle. And it is not even warm!

If its not getting hot then I'm confused lol. It sounds like a actual hardware fault. Sorry I can't help with this one

try and get it taken back to stock if you dare.
The phone hasn't been out 2 years yet, which is how long the warranty is.

Thank you! But is there any possibility to fix it without HTC involvement? Maybe it is not hardware issue ? Can it be because phone is rooted and I flashed many roms to it ? I didnt try AOSP roms since reboots started, I will try to pop in Cyanogenmod or other and see if I will get reboots.
Would rerooting my phone and updating my recovery fix the problem?
and Note: yesterday I tried to S-OFF my phone, but I can't even do that with my unstable MIUI. It rebooted in the middle of the process..

I had a similar problem, apparently it's not uncommon on the early revisions. I sent mine to HTC and they replaced the mainboard.

Thank you for answer! But what if my phone is bought through a contractor?
Can just call HTC and ask the for repair? Or should I contact my contractor first ?

Just give them a call and they will try to help you out. I had a very good customer service experience with them when my desire had some issues.
They will require a proof of purchase though. If you managed to get the receipt from your "contractor" (I am unsure what you mean by a contractor), then there should be no problem.

Sorry for misleading word, I meant T-Mobile. I bought my phone under contract. I think I have a receipt. I even have whole box and stuff of the phone somewhere in my drawer.(just sayin ). So how is customer service of HTC? Poor, good ? I heard you need to tell them that you did a factory reset and that didn't help. Is that true. Also if I will unroot my phone, will they know it was rooted anyhow?
Ahhh....this overheating issue seems common. How they can release faulty phones?? No clue.
thanks for answers mates!

In Singapore, HTC service is really good. Phone was still under warranty.
It took me just one (real) call to confirm a repair order. The first call I was just checking to see what options were available to me.
The second call was an actual repair request. And the third call was me pestering them for a pickup date. heehee
In Singapore, repairs were done via courier. They picked it up and 1 working day later, they sent it back.
Naturally, you will probably need to impress upon them that you tried everything to fix your phone (which I hope you did which includes proving to yourself that it's not the ROMs fault).
You will definitely need to reset everything back to zero. In my case, I downloaded an RUU to totally reset everything back to STOCK, which included removing clockworkmod recovery. You WILL need to create a goldcard for this though so bear in mind that it's not exactly a case of a simple flashing procedure. At least not if you don't already have a goldcard.

Sorry if I overread it at some point, but you speculated at the beginning there could be some faulty app causing this, but you never meantioned performing a full wipe. Have you full wiped yet? Just to make sure it is indeed no software problem.

Thank you for your answers. At the moment I have SuperNova classic ROM. ( 2.3.3 + Sense 2.1) But my phone crashes again and again, it is so annoying and causes me so much trouble.
I never tried a reset or unroot and return to original rom. Im just wondering now, would this help to remove or at least remove those reboots?
Today I was in my work and i was keeping my phone in my jeans pocket. it got hot as u would expect when keeping in pocket and suddenly it rebooten, then it went into a bootloop and started to bootloop 7 times in a row quickly. then again and again. It became very hot at that time.
For the interest, what exact hardware faults causes these reboots and why phone gets even hotter if you keep it on boot loop. If I keep phone cold, the rom usualy stays normal, without reboots. but as soon as I start using my phone, texting or calling for at least 5minutes of using it just reboots.
as I said- really annoying thing :S
I remember my happy times with miui, apps and no reboots Was fun!
cheers for helping!

I would give full wipe / factory reset a chance, and maybe RUU.
At least try it before sending phone to htc.

It is hardware problem, search forum. Fresh ROM without SD card, enabled WIFI and GPS, running G navigation, back of the phone is warm - restart after few minutes.
Maybe someone know how to read info form the phone right before reset? We could understand why the phone is reseting and hopefully add some patch.

Reboot-loop experience
Hey,
i had the same problem over the last few months: In the beginning my phone restarted only when it got hot, but it got worse over the last few weeks, in the end i was not able to use two apps at the same time (music and mytracks) or even to surf the internet longer than a few minutes. The problem did noticeably decrease when the phone was cool - tested by putting it on a fan or in the fridge. Yet, Skype was regularly killing it. As i really love my phone (and especially the AMOLED-Screen!) i did not want to resign. The battery cover contains some metal which is supposed to enhance heat dissipation - so i attached a little thermal pad to the hotter bottom of the phone to improve contact with the head spreader. Unfortunately it did not entirely fix the problem. Yes, it improved the situation a little, but it got even worse after a week or two - in the end i had to turn it in.
So i decided to take it to the Telekom-Shop. They were very kind and told me they would call the other day to confirm that the replacement would have been shipped. It took a few days longer, but i got a phone with the AMOLED-Screen! The employee said it was a used mainboard in a new case, completely refurbished. They only replaced the main unit, i kept the battery, sd-card, charger and so on. Now i have a working Desire again!

HTC Desire - Bricked? Constant Buzz.

Hi,
I had Sandvold's ICS 0.16 installed and disabled vibration when ring and my Desire reset...
Now, all it does is sit there with a black screen buzzing..
Battery out reset, removed sdcard, etc..
I've tried getting into recovery mode via power+back & power+voldn, etc.
No joy at all.
PC cannot see the phone when plugged in via USB (tried running RUU, that couldn't see it).
My main questions:
Is there any method available to recover from this? I've tried what I can (understand) but obviously no luck..
The phone's under warranty.. but guess this will be void as I'm s-off, etc etc? Will HTC be able to detect this?

See the link in my signature.

Thanks.. guess you meant the last link 'How the HTC works.."
If so. are you implying that my radio has corrupted and so it's shagged (or the bootloader's knackered... how could that happen?)
How can I tell which of those scenarios is the one I've got? Hpw do I know it the radio hast started?
If it is the radio that's knackered, I flashed that over a week ago and the mobiles been power-cycled many times in that period...
Or am I missing the point here?
I have another working Desire, could that help me in anyway to get the broken Desire to work....?

Oh well, with the lack of responses I guess the phone's bricked :crying:
Main question I have is if it's sent back to HTC, are they likely to fix it under warranty in its current state?
Added to this, anyone know what I did wrong, so I don't do it with my other Desire.

As I could see many users are complaining for getting a permanenr brick after installing ICS roms, and most of them after Sandvold one. Just take a look at bricked threads in the past month or so. Am I right?
Sent from my HTC Desire using Flashes and Thunders

Hadn't realised that - would have avoided the ICS route if I had.
Was happy with SuperNova until I thought Sandvold's ICS was stable
Still can't figure what actually went wrong.

It may be that it's not about rom, but you never know.

Reading that makes me think they won't since rooting your phone and installing custom roms is against the intended use by HTC and in this case it really wouldn't be their fault. Having said that, if you contact them and they say they will then by all means get it fixed and I hope it turns out well for you

"used with or connected to an accessory"..
Doesn't sound like anything to do with roms to me... just unsupported hardware..?
Ah , reading the next bit I see what you mean:
"used in other than its intended use"... well I used it as a phone ...

Exactly.

Mobile's been returned Hopefully repaired(!) - will find out when I get home..!
Still wish I knew what I did though that caused the brick - bit apprehensive about playing around with it now!
Bricks are relatively rare though I guess.
Looks to me that Radio was corrupted - ie no charging light, but it did constantly buzz...
I programmed the radio over a week before it failed.. could it have flashed badly and setting Sandvold's ICS to 'not buzz when ringing' accessed something bad in the radio ROM and caused it to corrupt??
This doesn't sound likely...?
Next question is (bearing in mind I'm gonna avoid Sandvold's ICS just in case it was that!), what do I go for.
Questions I have...
I guess for a fully functioning mobile, the only option is to stick with GB..?
Do I need to go S-OFF any more to install ROMs?
Do I need a custom HBOOT any more?

1. based on your second and third questions, yes, stick with GB. 'fully functioning' definition varies between users, but the fact that the JB and ICS roms have Alpha/BETA status should tell you what you need to know. the choice is still yours though!
2. not strictly necessary, but is much more useful if things go wrong. so use revolutionary to s-off
3. if you're asking this question i wonder whether you know what the custom hboots are? you flash a custom hboot depending on the rom's system size. should be in the first post of each rom, if not search the thread for 'hboot'...strictly speaking you don't necessarily need a custom hboot, but most of the time you'll run out of space much quicker if you don't. once you understand what the hboot partition tables are it will make sense . you need s-off to change hboot, so this pretty much answers question 2.

Okay will stick with GB for now.. then again the JB roms are looking better all the time...
Okay will S-OFF again.. just wondered if it could have had any bearing on why my mobile bricked.
You're right - not really sure what a custom Hboot is.. it allocates different sized partitions for specific roms then?
Will have a read to try to understand things a bit more.
Thanks for clarification or at least putting me on the road to clarification(!)

Typical - phone worked for 24 hours...
Now, doesn't power on.. screen stays black - no vibrate when I push power button.
Green led turns on when plugged into usb, when I press the power button the green led goes off, but screen still black - nothing happening.
Power button with 'back' or 'vol-down' depressed does nothing, black screen only.
Any ideas, or do I return it (again).
This will be the 4th time - will they be amenable to giving me a replacement do you think?

Well mobile back from HTC a second time; ran fine for a couple of days, so installed Supernova and all running fine now.
Gone S-OFF but left flashing radio alone - seems to work with 5.11.05.27 fine.
So that's it, will avoid ICS, etc just in case, but have no idea whether that's why the phone got screwed...

Mmm.. have now installed Mildwild with no problems..
Really think it was something to do with Sandvold'd ICS release, but have no way of knowing..!

[Q] xperia 6503 wont turn on after update

hi,
I have a big problem.. yesterday I updated zl 6503 thru pcc to the latest software 10.3.1.A.2.6.7, but when it succesfully finished I could not turn it on..
it was never rooted, I just updated it on 4.2.2 maybe 2 months ago and worked perfectly since
I tried every possible combination with buttons (up, down, power, off) but it just wont boot, just black screen and red light is on or blinking
the battery was 100% when I updated
I tried to repair it in pcc in support but nothing shows, I even updated it again thru sus, but it is always the same..
do you have any idea what it is or what can I do?
thanks

I flashed it but still the same, I think there is problem with charging, because when I plug it to power there is just red light, it wont get orange or green even if phone is plugged for hours
maybe this is why it wont boot..

strange thing happened, I already gave up on it and thinking I should take it to sony, but today I just tried to charge it and it did!
when it's full, I'll see if it works normally

it works perfect, seems like the battery was totaly empty, even though it was full when I did the update..
ok now i have another question, 2 months ago I made a backup (.semc-fullbackup) I have it on my comp, I dont know how to restore that file on my phone? anybody know where to copy it?

hi, still the same issue with ZL..
every time I turn the phone off, I can't turn it on normally.. I have to leave it for few hours and then I can start charging it (bright red led), otherwise it's barely red led.. it is like every time I switch the phone off, the battery gets totally drained, even though it is never under 15%, and I think that is the reason it wont turn on
is it possible that it's battery issue or software? let me say that this happened for the first time when I updated to the latest official rom,
now I flashed it to 4.2.1 and it's the same..

HI, +1 I am experiencing the same problem now. Did my own research here, and found there is a way to deal with this. Be patient and be challenged by the problem as this is the objective I believe of this XDA community. Coming from Galaxy S2 I have experienced difficult issues and was able to solve them knowing and understanding the design, and the configuration of the phone. So am not a total newbie to flashing and custom roms. Anyway I consider myself new to XZL and would like to do the critical solving by understanding first the Sony package because I believe not all android phones are made the same Software wise.
My phone is stock, non rooted with still locked BL (JB 4.2.2), it was acquired from a seller in stock and original software condition as I prefer the UI of Sony. Lately the phone strangely began to reboot for no apparent reason, until it decided to just stop totally, doesn't switch on. It will boot up to the Sony Logo then stops dead, and the only way for me to pass thru this state is when I attach the charger.
There could be two reasons I suspect: 1) Battery is drained (although I'm sure I have enough juice) and as mentioned the charger is needed or 2) Firmware problem.
I'll share details later but based on the above I'm more inclined to focus on the second (Firmware) suspect first. My phone still has both FastBoot and Flashmode so still not bricked. Are you with me?

tnx for reply, my phone is also nonrooted, I only downloaded official sony firmware
but I can't even get to the screen where is sony logo, it's dead completely, so I have to wait several hours (maybe the battery needs, I dont know) and then I can charge it.. but when I turn it off, it wont get on again..
I also thought there is firmware problem, but now I have 4.2.1 again and the problem is still here, so maybe it's not firmware?

Try flashing the .423 or .67 stock rom with the latest flashtool for xperia devices (http://www.flashtool.net/download.php).
Maybe pcc screwed something up. On my old Xperia Neo I had several problems after updating with official Sony tools.

Hi Skyline_slo, just an update of what I have done; 1) I read this "http://forum.xda-developers.com/showthread.php?t=1849170" to learn and was able to
make progress on my unit. I drained completely the battery to be able to reset the kernel (took about an hour or so) because from what I have learned on start-up the kernel controls the intial process before the ROM kicks in. So if the kernel has issues, there is a chance that it will reset to default when the power runs down. I was able to successfully reached the red LED state which is the slow charging mode. This state is when the Battery icon with lightning appears on the center of the screen.
Guess what? I was able to boot my unit completely and test the new FW (while attached to the charger) and subsequently made adjustments on the recently flashed firmware (first time by the way using flashtool)
After this, I checked the service condition of the unit using the code *#*#7378423#*#*, and took note of the changes the flashed FW. Then I decided to power down my phone to accelerate the charging time and completely settle the new firmware's adjustments. My hopes are up and high again knowing that the thing is not bricked and just experienced a minor glitch probably the software.
After more than two hours I checked back and switch it on again and to my surprise it doesnt boot, just stock again in the Sony logo. Was a little disappointed but the thing here is, I made progress by ruling out that the ROM has issues, second, that draining the battery will reset the kernel and would lead to completely boot the system. At this point as previously mentioned in my earlier post, my other suspect is the battery so I will work on it today and relay/share whatever I encounter.

hi jun1662,
I'm glad that you're making progress with your unit, because I simply dont have any ideas left what to do with my unit
I flashed it to rom .244 and now I just wont turn off the phone, because I will not be able to turn it on normally again
I'll wait for next update 4.3 and then try if it's any better, but I doubt it
it may be hardware related issue, but why is working perfect when it is turned on?

Update: Definely ruled out software, and made some test related to supply meaning battery, and the result is my battery is defective, it may
provide you with a ample charge but in reality, current is not enough to sustain the requirement display and cores, so it seems the main culprit here is
the battery. Also did my own checking on the other post and inquired on how the problem manifested, and the solution is replace battery.
Going to have my unit serviced for battery replacement, and this is my final actions, if this proves pointless, i'll provide answers tomorrow. Keeping
my fingers crossed.

Camera (stopped working) issues (H815 europe)

I'm having some rather annoying issues with my G4, the camera barely works, sometimes it opens but i get a black screen, like my finger is on the lens, but it's not. Sometimes that results in an error message "Unfortunately, camera has stopped" or "camera unavailable", sometimes it just stays black and sometimes the phone reboots.
And now lately i can't use the flashlight anymore, says it's already being used.
The camera works again after i reboot, but most of the times i have to reboot multiple times.
I read quite a few forums and even threads here and tried pretty much everything (clearing cache, uninstalling LG Smartworld or something like that, removing the battery, etc.) and nothing really worked, so yesterday i finally decided it was time for more drastic measures and i unlocked the bootloader, installed TWRP and then installed Imperium ROM v14 and it seemed fine but today i get a black screen again. I didn't restore any of my previous apps and settings on purpose, to see if they were causing the problem.
Someone here suggested (to someone else) to try flashing KDZ or something like that, i and probably the other guy, have no idea what KDZ is or where to get it.
I bought this phone used almost 2 years ago, so i have no warranty. Didn't have any issues until about 6-9 months ago and they seem to be getting worse, battery life isn't what it used to be either.
My only options are to try a non-stock rom like CM, to go back to an android 5.0 based rom, or to sell the phone as a semi-defective product, maybe i can get a used S5 for it.
This is very frustrating and somewhat ironic, since i bought this phone because it had the best camera at the time and i barely use it for anything else than taking pictures.
I'm never buying LG again.
This is a fairly common issue, maybe common enough that it should be a sticky.

Got the same issue after display repair. Camera got broken. I always needed to reboot phone so camera gets working again. Only fix was to send it to repair. They replaced camera, after that it worked again normal.
For me it was guarantee because before display repair I didn't have issue like that.
You can replace your camera, I don't think it's so difficult.
It's also not that expensive:

OK, that's something i didn't even think of, so it's definitely a hardware issue ?
I read up on this KDZ thing and it seems to be a firmware updater for LG phones, would using that help ? and/or is the risk of bricking he phone too great ?

It is hardware issue. I had exact same issue. I was in stock. Didn't modify anything. After display repair they completely reflashed it. Of course you can try other firmware, but really had the same issue.
I didn't spend so much time on it, therefore don't remember exactly if i got force closes.
I only remember that the camera worked, later i got black screen, i could see the buttons, but no pic. After restart it worked again.
I also thought software issue because after restart it worked. Tried really everything which was possible without unlocked bootloader, but didn't worked.
I can't say it is definitive, could be also a motherboard issue. Or an other part of the camera (flash light, ir sensor), I only tell you what was replaced on my phone.
I would try it, camera is not so expensive.

You convinced me, i just ordered a used one, it will be here be thursday i think, the guy also said it could be a motherboard issue, i imagine that isn't very cheap or easy to replace ?
Also lately i have been getting flashlight issues too, says it's already in use, so maybe the flashlight is broken too or the camera is causing that too.

Flashlight is camera related. I believe i had the same issue with flash light.
I think I tried to use other camera apps, i always got the message, that it is in use.
If it is mainboard, you should buy a new phone. Mainboard is too expensive.
But I don't believe in it, mainboard issue your phone wouldn't start anymore as we know how sensitive G4 is.
Flashlight would only freeze camera while making photos. You can check ir sensor, use an other camera and check out if there comes light from sensor.
I don't think that would be the reason to stop the camera from working.

So if the back camera is broken then why doesn't the front one work ? is it because they both run in 1 app and are kinda tied together ?
The replacement back camera should be arriving in 1-2 days.

I have had it where there camera crashed out the box
Back on my g2. It was a refurb. And ended up being corrupted firmware and or kernel. After a reflash of firmware worked great. Ures sounds firmware related if the front aint working either. Have u tried any 3rd party camera apps to see if same results

Strange way to write 'yours', so using KDZ to update or reflash the firmware might help ? is it risky ?
I haven't tried it since i installed the Imperium Rom, but with the stock rom any and all apps that used the camera wouldn't work.
This all started after i sideloaded the google camera app (to take VR photos), which was not supported by the G4, i wonder if doing that is what caused all this.

There havebeen a few camera failures and a good majority have been hardware related.
As long as u dont downgrade ure firmware not risky. And yes if thats when ure issues started i would safely say that is the issue. U may just try reflashing the rom ure on clean wipe all but ext sd. And start over and see if it persists

Well i just went from stock to Imperium and while unlocking the phone everything was wiped anyway so doing that again won't change anything, unless there is some cache or something i don't know about.
Anyway, i ordered this new camera so i'll wait for it and if that doesn't work then i'll try reflashing the firmware.
Are newer LG flagships (G5, G6) just as poorly built ? cuz i'm pretty sure i'm going back to samsung after this.

I think they are. Dont know forst hand. I love my note 5. My battery xied in it the other day so im waitin on a bettery hopefully it works. Im been so fed up with lg.

got the new camera but haven't installed it yet since my phone has other issues right now, like freezing, random restarts, the quick toggles are gone, my wallpapers seems to have been removed, etc. and now it's stuck on booting (not bootlooping though)
I would like to reflash the firmware (KDZ) but the get the right one i need my IMEI number (the one underneath the battery seems to not be the one) or to see what software version the phone is running, i would need a working phone for both.
Would reflashing the Imperium rom fix this ?
The imperium rom is v20P, but there is no kdz firmware like that only V20D or V20G

Have that for months
That freakin camera issue is haunting me for months. I have tried reflashing EVERY freaking rom(stock,cm,everything) and it doesnt change anything. I have teardown my g4 to parts,plug them in and still the same.Sometimes works for a week,sometimes doesnt work for 1 month. I don;t get it. Finally someone with my problem! Man can you replace the camera module and tell me if that works so i order mine?

Did you try reflashing the firmware ? (the KDZ thing)
Also no, i can't try that for you right now, like i wrote previously i got bigger problems, also i got my camera locally for like $15, if you tried everything else that is not a lot of money to spend, and if it doesn't fix your problem then you can just resell the camera. Now go do it.

i reflash using kdz and other programs. To give you the prespective that even deletes the twrp and fully wipes all phones data and flashes the new ones.If you flash yours it sould be fine because i have flashed nearly all the letters (ex. v20d,e etc). Flash it see that the camera is not fixed and then change the module to tell me..in greece new camera costs 30 euros so it's not that cheap for me to spend and then does not fix nothing

Well i didn't buy a new one, i bought a used one from local listings site (like craigslist in the USA or Kijiji in Canada, every country has their own) and if the new camera doesn't work you can sell it for the exact same amount, all it will cost you is shipping and time.
If i can fix the booting issue and i still have camera issues i will install the new camera, but don't wait for me, it could take weeks, or i could just get angry and buy a used Samsung Galaxy S5 and throw this in the trash (or most likely sell it for parts)

It's not a shop, it's a website like ebay, anyone can sell anything there, you have many sites like that i'm sure, every country does. 99% of things sold there are by regular people like you and me.
Google "used lg g4 camera for sale" (in your language) and the first 5 websites will probably be what you are looking for.
This is what ours looks like https://www.olx.ro/oferte/q-lg-g4/, there are at least 10-20 smaller sites, there are even facebook groups, where people post the stuff they don't want anymore.
You're saying you have none of these ?

Persistent sound issue no matter what

I've done just about everything. There's a log cat below. EVERY ROM, EVERY KERNEL STOCK OR CUSTOM, this issue is there after the first reboot. Im only going to answer every question that goes like "have you tried...." With a full rundown of what I did and results. I will remind I've tried every custom nougat rom, stock or custom and I've tried stock marshmallow rom to. Also some roms haven't even had sound on first boot. Some roms will work for a bit then they will do a soft reboot that takes 30-45 minutes to complete. Then have no sound. I'm open to taking my phone apart since my screen is fu*ked up. Im begging at this point I love this phone, I've had it for 2 months, I don't want to have to buy another one.

Tried unbrick tool yet? That may have a slightly different effect than just flashing stock ROM (as it completely nukes the device and installs everything again).
Anyways, you may have a hardware issue. In that case taking the phone apart won't do much ... You can only check the connections, that's about it.

I did actually brick it awhile back trying to solve that damn sound issue. I used the mega unbrick guide to fix it, I can try again. Cause hell who knows it might fix it. Thanks for the recommendations.

Found out it is hardware i narrowed it to the aux port board which is what the fingerprint sensor, microphone, speaker connect to. I'm ordering a new part tomorrow for it

Did you find any solution? Im having the same issue and trying to figure out how to fix tihs
