Official HTC EVO Random Reboot Thread

From searching, it looks like tons of people are having random reboot issues with the HTC EVO. Let's make one thread to put everything so maybe we can figure this out.
Side note, it looks like the HTC desire has the same issue:
http://forum.xda-developers.com/showthread.php?t=676402&highlight=rebooting
So post what you've tried that hasn't worked.
If you think you have a solution, share

One thing I've noticed is it seems heat related.
I've installed temperatures monitors and it seems around 32 degrees Celcius is around when it reboots. It will reboot loop usually. This can be cured by pulling the battery and waiting for it to cool down, or just put it in the freezer for 4-5 minutes.
I've tried underclocking it with the screen dimmed way down, and running it without the back cover and it still overheats.
For me, the problem came out of nowhere. I had the device for over a month with heavy usage and no problems. My current GUESS is it must be a physical problem. Not enough thermal grease or something...
It looks like the HTC Desire users may be getting replacement motherboards to fix their issue.
Does the HTC EVO and Desire share parts?
From other threads it looks like:
Root or Stock - Doesn't matter
Radio version - Doesn't matter
Rom version - Doesn't matter
GPS Fix - Doesn't matter
GPS turned off - Doesn't matter
3G data, 4G data turned off - Doesn't matter
Hard Reset - Doesn't matter

Found this on the HTC Desire reboot thread:
Latest test list for HTC Desire RR (Random Reboot) problems:
-All phones with s/n HT03 to HT07 can get this problem (Minor problem from SH09 so far)
-Starts around 1.5 to 3 months after use
-Reboots get worse over time
-Firmware and android version doesn’t matter which you have
-Force apps2sd doesn’t matter if you use it or not
-PVT1 or PVT3 or whatever doesn’t matter
-Screen type, doesn't matter if you have AMOLED or SLCD
-There seems to be an antenna/radio/simcard issue also
-Overheating causes reboots too
-Reboot is not always temp related
-SD card size doesn’t seem to matter
-Having apps on SD or not doesn’t matter
-Size of files on SD doesn’t matter
-Rooted or not doesn’t matter
-Motherboard changed after repair doesn't always fix it
-Sim locked or not doesn't matter
-Provider doesn't matter(vodafone, kpn/hi, T-mobile etc all got it)
-Most likely hardware issue, sense flashing won’t fix it, yet changing motherboard will
-Restarting doesn't fix it
-Factory resetting doesn't fix it
-Changing/buying new battery Doesn’t fix it
-Using app killers or shutting down some services yourself doesn't help
-Leaving all settings on default doesn't fix it
-Plugged into car charger in the past doesn’t matter
-Hboot version probably doesn't matter (still not fully tested)
-Having a phone cover or not doesn’t matter

wifes phone has been doing it very bad...one that has never been rooted...
was going to root it and try new rom but seems to be a hardware issue.
any other comments on this subject?

My stock rooted Rom just rebooted for the first time today. I really don't rememebr what I was doing st the time....but this has never happened before. I assume there's no event log to check.

I had been facing this with increasing frequency. I got the phone on launch day, and the problem started over the last month, getting worse all the time. I agree with the OP that there does not seem to be any obvious cause -- sometimes it is heat related, sometimes not. Any time I push the phone (run psx4droid, or navigation + anything else), and sometimes even with lighter usage, like on a phone call. Unrooting did nothing to stop the problem.
After extensive searching, I found three possible causes: bad battery (I tried a new one and the problem continued, but this seems a good starting place), bad memory blocks, or bad processor.
I was unable to find any solution to this problem. I took my phone to Sprint today, and they told me that their tests didn't show a problem. Then I made it happen in front of them (launch navigation to anywhere, then a couple more apps, then boom, reboot) a couple times (really, after the first time, letting it turn back on pretty much caused it to happen again).
After that, they agreed to replace it. I do have the TEP, but they assumed that the problem was hardware related so I don't know if you have to have it for them to replace it.
Strangely, they gave me a white one as a replacement.
I haven't had any problems with the new (well, re-manufactured) one, and I hope it stays that way, but I guess only time will tell.

I'm currently experiencing the problem as well, funny thing is every time it happens, the phone is NOT in use, simply sitting on table or desktop in standby. This happens about once every two days.
Currently running rooted evio2 1.3.1

Wow, I was about to start this thread, when I saw this. I guess I was like 10 minutes late. Either way, i believe something messed with the hardware. My little bro cracked my screen badly, so I am getting a new evo anyway, but will I be able to get one free bcuz of this? This is really a terrible problem. Somebody needs to de-assemble their precious evo and see if there is an obvious problem. thanks a bunch. Subscribing.

same here.
happens mostly when on the charger and i am using it at the same time. so heat related seems likely.

can anyone get a logcat of it happening?

I called sprint support and they said it's defective to return it.
Taking it in for replacement today.

Sprint replaced mine for $35 [a refurb]. That's the end of that.
But now, I can only use the speaker to hear my callers. Gotta go back and get another!

My guess is the new update could be putting a lot of strain on the battery but who knows? I haven't experienced it but maybe its because I'm using the extended mah 3500 seido battery.

No, I've got the 3500mAh Seido battery too.
I don't think it's strain since mine has gotten worse. AKA the amount of usage it take to make the phone reboot has gone from hours of use to minutes.

Actually I just had a reboot lol.

Same thing here. I posted my issue in the rom threads i used, and everyone ignored the issue, lol.
For me, I noticed it about a week after using roms with the new software update (3.29). It happened with navigation, launching multiple apps, running quadrant, etc.
So yesterday I installed DC 3.5 from scratch, turned nav on and let it sit for a couple of hours. NO reboots. Before, after 10 mins of the screen and nav being on, I'd get a reboot. Has anyone else tried this (or willingly to try it)? I switched back to my nand backup, ran quadrant -> bam, reboot.

I bought my EVO on launch day (HW Version 002), and have not had any problems until around Oct 13.
I took the phone on a trip to Orlando, and as soon as I got off the plane and turned on the phone, the problems started happening. It has been happening ever since, even since I returned home.
I bought my phone at Best Buy, and have had their Geek Squad send it back to try to fix it. I also added the complaints about screen separation to the workorder so that they would be more likely to replace the device. Hopefully, this fixes the issue.
I also think it is heat related, but I don't know why it is just now becoming an issue. Just to make sure the folks at BB could see the issue happening, I put the phone in front of my car's heater for a few minutes, then started up Google Earth, and was able to make the phone start boot looping while I walked into the store.
I tried hard reset, soft reset, update prl, underclocking, GPS Reset, new battery, new SD Card, and none of those things worked. I wonder if the removal of the 30 fps limit in the last update caused some type of heat damage?

I just had a reboot last night while trying to look at a picture I'd just taken in the Camera app on CM6.0.0. Only the 2nd or 3rd time it's happened. Still annoying though. Hope it doesn't get worse.

I reset mine back to stock. Unrooted it and everything.
Didn't fix the issue for me.
Now I did try erasing all the stuff that's erasable inside recovery and it seemed to go a few days without a reboot. Not sure if that was a fluke or not.

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?
Sent from my HTC Desire using xda premium

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.
greets

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!

Similar?
Hi i on the other hand have similar problem, qiute anoying one, my desire, cm7 hboot, s-off, insert coin cm7 rom, have phone freezing in diferent situations, sometimes its working sometimes just freezez and i need to get battery out and turn it one and sometimes several times in row to get it working again????

[Q] One X Screen taking progressively long to turn on

Hi,
I have searched the forums for a problem like this but in vain, so posting here.
I have an HTC one X (international) running stock 4.2.2
After upgrading to 4.2.2, I noticed the wifi was not working properly and the network signal was also intermittent at best.
I sent the device to HTC for repair, and was told that the motherboard needs to be changed. I had to shell out INR 13.5k for it, which is almost 60% of the cost of the phone today.
I got the phone back with the problem solved. However within a day, another problem has cropped up. on pressing the power button in locked state, the screen takes a long time to light up. I have tried factory reset a couple of times, tried power+volume button, everything under the sun.Initially after reset the phone will lock and unlock fine. However within 10-15 minutes the duration for screen to come to life increases progressively, sometimes taking minutes to turn on.
Is there any solution for it? I'm sure HTC has stuck in some refurbished old motherboard in this, but i dont want to spend any more money on this..
Thanks

so i stick with it..

[Q] LG G3 Turning Off Problem

I have randomly started experiencing a problem where my device would turn off randomly which has gradually gotten worse to the point where it's stuck in a boot loop sort thing and will shut off randomly during boot then restart.
The problem started by every now and then (sometimes not happening for a day at a time) the phone would turn off then turn back on again gradually getting worse. The problem started when I installed the latest update during the update the screen froze (no it was not interrupted in anyway and done officially through the phone) so after leaving it overnight and it not progressing I took the chance and removed the battery. it then turned on and finished the update without an issue. The phone has since as I explained got into a 'boot loop' sort scenario where it will work if the charger is plugged in but couldn't be a battery issue as doesn't turn off if I put it into download mode. Things I've tried: Doing a complete reset- Still no fix. and now today I entered download mode and re-installed the firmware which was successful but still no prevail?! What the hell could this be?! Thanks

Maybe it's a hardware issue

hi, where did you get the firmware? it could be corrupted. if I were you I would download again the firmware and reflash it.
after that I'll do a hard reset.

Well i guess im not alone as i have the same exact problem as you do! WHich version do you have? I have the White T-Mobile version and i bought it the same week it was on sale i felt that i got a phone that was part of a bad batch because of some problems ive had with it but i didnt buy insurance for it. i was on LG's OS and it started to get worse and worse so i restored it and went to a lollipop rom. its still happening but it only reboots once. however, as soon as i start using apps it reboots on me. i want to unroot it but at the same time i dont want to go through the trouble of rooting it again. Any ideas of what it could be?
My problem just randomly started happening and i noticed this started happening strangely after my phone completely died on me and didnt want to turn on so i connected it to the charger and it started charging but had a yellow warning triangle somewhere on the screen.

Hey, nice to hear someone has the same issue, I however hvent had the yellow warning triangle come up yet, as an update all of a sudden it keeps turning off as soon as it boots even on charge!!!??? It just keeps getting gradually worse?! However I have noticed the battery % it shows when turned off is 100% and very randomly it displays 70% then when the phone boots it will show 2% for the 2 seconds it stays on before it dies?!

Wait now it reboots on you even if its charging? I too started noticing that with my battery . if I turn it off and charge it it and lets say it says its at 75% well I turn it on and its like at 40%? I really don't want to buy another battery but I actually hope the battery is the culprit. There's a guy with a G3 in my school I'm going to see if he let's me try his battery out on my phone I'll keep you posted

Hey sorry for taking so damn long on replying i've been busy studying for some exams.
I've got good news for you though, i took my phone in to T-Mobile and showed them my problem. Without me putting much effort into persuading them, they shipped me a new phone, and no i didn't pay for insurance on T-Mobile, this was covered by LG's 1 year Manufacturers warranty!
Anyways, I received the device but did not receive a battery. So i tried my battery on the new one and what do you know? SAME PROBLEM!
So yea you should either try to unroot the phone and take it to the store but don't mention that you think its the battery, they'll send you a new phone! Then just buy a battery online or call them after a few days and say your problem is still occurring with the new phone and see if they send you a replacement battery, im a little skeptical on this second option as id rather keep this new phone haha

Hi, even i am having this problem, my phone is a D855 and in my country (Mozambique) i am not using a contract so its different than US, we have a LG store here but in the LG website our country is not stated. So only way is to go to a trusted Store that repairs phone here. My question is that, when its not connected in the charger it just keeps reboting (the notification LED doesnt even blink) infinite times. At first i thought it was a software but after going from Stock to Cloudy to CandyRom the problem was still there. Then after i plugged in a charger the phone would succesfully boot up and i could use it normally but had to stay connected on a charger. So what have you done to fix this? Did you replace the battery with a new one and then it stopped rebooting?? Please help me as i want to buy a new battery but first want to confirm if its the battery at fault....

Hello buddy, sorry for taking so long to reply. Im usually not on XDA too much. Yes i solved my issue with a new battery. I tried my bad battery on 2 lg g3s and it rebooted both. I also unrooted my phone and flashed a completely stock update and was still having that issue.
I hope my response isnt too late for you!

No problem bro! Got a new battery and do far my phone doesnt reboot, but the only problem i am having is that my phone shutsdown at 30% battery and when trying to turn on it says it has 0%

Im having the same problem gotba new battery and no different so annoying

Best thing just happened. I had the G3 for a while and my first one had an issue and had to get a warranty replacement. Long story short... I got two more G3s from T-Mobile that were defective and most carries have a policy where if you get 3 warranty replacements you can chose a different phone. To wrap it up, you can ask for a phone of equal or lesser value when purchased from the carrier (I bought mine off eBay and they didn't even notice, I spoke to several reps and no one caught on.) So they can either send you a whole new phone, a new battery, or in my case: I received a new LG G4 since I had gone through three which pretty much anyone can do with a bad battery.

Guys. Im having this same exact problem on my LGG3!!!

Expired Battery or Faulty Power Button could be the culprit
This issue just started happening to my LG G3 over the last 2 weeks. I've had my LG G3 for exactly 15 months and all of a sudden it started cycling endlessly and if it did get to my locked screen and i tried to unlock it it would just restart again.
I found that when I plugged in the device to a wall charger or high power power brick, it would halt the reboots but otherwise it would get stuck in an endless cycle of partial reboots (when it did stop after plugging in, I would find all my apps still open and waiting for me, so they weren't real power cycles).
One of my coworkers has a newer LG G3, so we swapped batteries and immediately he had the cycling issue on his phone and with his battery in my phone the issue vanished.
On closer inspection, my battery was a few months past its expiration (FYI to anyone with a LG G3 - your battery will expire more or less exactly as its warranty protection does!), so went and bought a new battery and everything is fine now.
For those of you who have tried replacing the battery and find it still occurs, another coworker said his wife had a similar issue on a different device and it was resolved by having the power button replaced, so it is possible that this could be a factor also and you should have your phone sent in for inspection/repair.
Hope this is helpful for some of you.

I've had the same issue since February, when my phone was about 17 months old. It kept turning off saying SIM card not detected. I tried replacing the SIM card and washing that area with alcohol with no luck. Then I replaced the battery with a second one that came with the phone which I'd never used, but I noticed no difference. It also has no phone service for several hours without my knowledge. LG just told me to reset the phone, but it looks like that doesn't work from what I've read. T-Mobile said they'd give me a new phone but there are no G3s in stock and offered me a Samsung 3, which is three years old, so I am worried that it won't be able to handle the software updates. It's ridiculous that a phone that costs this much won't even last long enough for me to pay it off. My last phone was an Iphone, which I had for more than four years.

I had the exact same problem a few weeks ago, posted a detailed explanation of the problem and got 0 replies and a few hundred views (thanks guys!)
Easy answer:
Replace your battery
Thats what I did, and the problem is now gone. When you do get a new battery make sure you drain it completely first, then charge it for 4 hours without exceptions.
I tried factory resetting, installing a new firmware, going to stock and going to custom but nothing worked.
The girl in the shop where i bought the battery surprised me, i just asked her if they had one available and her immediate reply way "why, is your g3 stuck in a boot loop?", apparently EVERY SINGLE PERSON that bought a g3 battery from them had the exact same issue.
Now the problem is gone, and my phone actually lasts longer than before.

Hey, I am having the EXACT same issue. LG G3 was stuck in an endless loop, replaced the battery, now it works down to about 30% and shuts off. When I try to restart it says 0%. I even tried a third different battery, and still getting that 30% shutdown. Did you ever figure out what it was? I am wondering is it something to do with how the phone reads the battery charge i.e. does it think the battery is dead when it gets to 30%? It has e stumped!! Any advice would be most welcome. Thanks.

wtf,actually same with my LG G3,after when I bought a new battery. Shutsdown at 30% and it says has 0%.

same problem

M8 Wont turn on after Charge

Hello
I hope you are fine I need your support I don't I don’t know what I need to do :crying:
Yesterday I turned off my Cell and put the charger (Without Problem)
Today in the morning I tried to turned on but I couldn't Turn on and just had the green LED stuck
Exactly two weeks ago I rooted my cellular and S-Off with SunShine do you think it was the root casuse of the problem ?

Try holding power and vol up, for a pretty long time (maybe 30 seconds or more).
This is on the stock ROM?
I have had a similar thing happen twice in the last month or two: charged overnight and the next day it wouldn't turn on, but no LED at all. Holding power and vol up turned it on, and it worked fine after that, and with 100% charge (a bit surprising, I thought the battery had drained somehow to cause the no power on condition). This is on a custom ROM, so not sure if that is the cause. But I've never had this happen after owning the M8 for more than a year, it started only recently.

Hello
First Thanks for your kind support
This is on the stock ROM?
--> Yes I Installed the ViperOneM8_4.5.1 One Week ago after
Thanks for you early answer after your recommendation my cellular Tuned On :good: and exactly happened according with your comment the battery was not 100% charge this had 85%.
What is your recommendation ? Do you think I need to change for another Room?
Do you think If I continued with this room can damage my Cellular?
Thanks in advance for your support

I'm not really sure what the problem is. I only know I've had a similar thing happen twice. Its been very irregular (maybe 2 times in 2 months) and easy enough to turn the phone on by the key combo I stated. It just led me to panic the first time (as it probably did for you).
I don't think changing the ROM is necessary, if its even related (just guessing). But I also happen to be on a M9 Sense 7 ported custom ROM (S.ROM). Coincidence . . . or something more? Can't say. At best, just a hypothesis.
Don't think it will damage your phone. But again, I can't really be sure.

Hello
I hope you are fine.
Thanks for your early answer and I understood your comment.
I have another theory now when I turn off my cellular and put the charger my cellular show the energy percentage but in some cases show the main screen of the TWRP (one time energy percentage and one time main screen of the TWRP)
I detected this issue when I rooted my cellular and installed the TWRP but I don’t know if another person have the same situation or what is the root cause of this behavior
Does anybody have the same situation with the TWRP when charge the cellular?

The issue with TWRP showing when charger on and phone off, has existed from the beginning as long as TWRP has been on this phone.
I don't think its related, since as mentioned, the "black screen" issue when charging has only happened to me recently.
