[EVO 4G Q&A, Help & Troubleshooting] Zyzzx:
I was told on the phone that it is a known issue that it overheats, if Sprint diagnosis it as that, and will replace your phone for free.

I went to a Sprint service store and they said they fixed it. I turned on GPS and downloaded stuff in their parking lot and took it back in. They said they put the old battery in and said it should be good now, I opened GPS and it reboot once again. Now they said they would have to replace it and charge me $35, I told them what sprint on the phone said and they said they had to charge me. I told them to bill it to my account and called Sprint after I left and they subtracted it from the account. I did NOT have any form of insurance. They ordered me a refurbished phone and it had a power button hardware issue. I went to a different place and they ordered me another one for free, another refurbished one. I happened to be somewhere else a day early from when it was supposed to arrive and they said that they are giving out new 0004 EVOs and not refurbished ones due to the fact that Hardware 0004 fixed the overheating and another issue that the 0003 series were having. They said that all Sprint stores were supposed to giving out new ones.

Bottom line/in the end, I got a brand new 0004 for free after my one year mark and without insurance.

I finally have a non rebooting EVO. My EVO was from Radio Shack and was almost 11 months old. I called sprint and advised that I downloaded Neocore and turned on all my radios and than ran Neocore and my phone rebooted in 4 minutes. Sprint's troubleshooting guide for the EVO says that if it reboots in 30 minutes to replace the phone for free. When I called Sprint and told them what I did with Neocore and my results they immediately sent me out a reburb without doing any troubleshooting. The reburb I got could not be activated for some reason even with tech support trying for an hour. That refurb was hardware version 3. Sprint than sent me another refurb with a new battery and charger. I was able to activate the new phone which so happens to have hardware version 4 and I checked and it only had 10 calls on it for 14 minutes total so wasn't a very used phone. I sent my old battery and charger back to Sprint and my new phone is running flawlessly. I have ran it pretty hard and gotten the temp up to 41 degrees celcius with zero reboots. So far I am happy with Sprint taking care of the EVO reboot issues even if you didn't buy the phone directly from them. Also note that my first phone was hardware version 3 as well. Hardware version 4 is the newest and I haven't heard anybody with hardware version 4 with reboot issues.

New EVO

I'm on HW 002 from day one and about 1 month ago my evo started rebooting. The only thing I can link it to is CM7.0.3.1. I took it to sprint and the guy was super helpful. He said he will give me a new refurb even though mine is past warranty and I don't have insurance. He warned me not to take my rooted evo to other sprint stores because they will flag it as being rooted and not void any further help.

Make sure you are talking to a friendly rooted sprint tech before exposing your rooted evo and then you can get whatever you want.

My old EVO was having the same prob got a new one and it hasn't done it at all so I took my old one apart but didn't see no obvious signs (no burn marks or signs of heat damage) but I'm no expert but still no obvious problem
[EVO 4G Q&A, Help & Troubleshooting] jeffdsmith:
Definately heat related. first started when tethering over 4g while charging in car 2 days ago. now I cant get it to run for more than 2 minutes without going into a boot loop. had to un-root it (so I could return it with a month left on "warranty") by laying it on a bag of frozen carrots. been running fine on the bag of frozen food now for about an hour, carrots are melting though.

unfortunately, used the ruu method of unrooting and cannot get it to flash unrevoked-forever-son.

unrevoked 3 comes up with radio error, so I can't reflash custom recovery the easy way to use unrevoked-forever-son.

any Ideas?

I was having the random reboot problem any time I used data. I still say random because sometimes it would go for 5 minutes, sometimes an hour. However, it did seem to follow a heating pattern. The more data I used, the hotter the phone got, when it got to a certain temp, it rebooted. That is unconfirmed, and I should of measured the temp, but I just wanted to get it fixed.

I ended up calling Sprint after reading everything that was posted on xda, and evo board, and another android board. Let me first mention my phone was rooted and running MIUI. Sprint's first trouble shooting step was to do an HTC update, which force closed. The gal took me to the next step instead of asking about my phone, the next step was to do a factory reset. Which she asked me to go into the boot menu and clear personal data. That isn't a factory reset, btw lol. again, without telling her anything, i did it, and she called me back in about 40 minutes to confirm the rebooting was still happening. during those 40 minutes, i did a real factory reset, flashing over to the original sprint evo 4g rom, clear personal data again, do the updates, etc. My phone now reboots on boot. the sprint version of the OS uses so much data, it just cycles until it get stuck, vibrates a few times and goes black and flashes the green light like i have a new message.

Sprint is sending me out a replacement free of charge.
[EVO 4G Q&A, Help & Troubleshooting] monkeychef:
Interesting. I just starting having this problem while running Kings Alliance last month. My phone is HW 0003 from April, and the issue has been happening more often. I am currently on MIUI with Tiamat.

It seems like heat would be the issue since it doesn't matter what ROM or kernel you have. Just so odd that it is happening.

Who knows, maybe they won't have any refurbs when my issue gets bad enough for a replacement and they will send me an Epic 4G Touch/Holiday/Kingdom/Something Awesome! (More of a wish than an actual expectation).
[EVO 4G Q&A, Help & Troubleshooting] Lacedaemon:
My Evo 4G randomly reboots when I'm running 2 or more big things simultaneously. My Evo will also heat up before rebooting.
[EVO 4G Q&A, Help & Troubleshooting] aliendev:
This rebooting is solved. The data causes the evolution to heat up, if it reboots its a hardware issue. Call sprint go threw tech support steps, get a replacement.
[EVO 4G Q&A, Help & Troubleshooting] Stovepipe:
Me too.. =-/

Same problem as everyone here, but mine seems random. Tried underclock, moving the partition blocks, to some but not total avail.

I figured it may've been bad memory blocks, so I tried using Calk's repartition, expanding the system partition to 425MB (thus losing some data space). I did this assuming that the system partition wouldn't grow that large, and it would force the other partitions to use different blocks in the device. Actually worked quite well, much fewer reboots than before, but it's not perfect.

My next attempt at this will be putting a small amount of arctic silver between the silver heat shields (under the meid label) and the chips. I've already opened the phone, so I've nothing to lose. I'll repost my results...

FWIW: the most stable ROM I've used thusfar is "SalvageMod". My worst luck thusfar has been with Fresh 3.5, though I'm sure the ROM isn't the problem. And, to clarify, the "most stable" means the fewest reboots.

Should also add that I'm using my Evo on Pageplus, and thus do not have Mobile Data or GPS turned on... so it may not entirely be the data usage.
[EVO 4G Q&A, Help & Troubleshooting] Stovepipe:
Thermal paste applied.. now let's see what happens.. so far, so good. :rolleyes:
[EVO 4G Q&A, Help & Troubleshooting] thoth_19:
Stovepipe Thanks for this, will be keeping up with your steps to get rid of this pain in the a$$ problem. If you need a tester let me know. Have HW 003. I'm repartioning as we speak to see if it will help me.

FYI: Too fond of my own evo due to case mods and would be a pain to go through sprint to replace, so like you I'm all for fixing the issue if possible!
[EVO 4G Q&A, Help & Troubleshooting] Stovepipe:
I'm hesitant to call it "fixed", but I think the thermal paste made a huge difference.

I've yet to have the phone reboot or FC at all, and it's been running since my previous post. I've loaded angry birds, surfed the web via wifi and did whatever I thought would load down the processor of the phone. Nada.. works perfectly. In fact, it seems like it runs much better; often before the phone would restart it would begin to slow down. So far, none of these symptoms have happened. :)

I'm using HW003, which seems to be the one with the problem.

Will keep you all apprised of the progress. I don't know if I can post pics to show where I'd applied the paste, but if so, I'll do that later on.

@Thoth.. I don't think repartitioning will do much for it. It seems like a heat issue, and I'm now running with the standard partition layout.

@Stovepipe

You Sir are correct, Repartioning was as productive as a midget in a foot race, But was worth a try. I am picking up some thermal paste and seeing what i can do. In theory this should fix the issue, it can only help. Looking foward to pics from you if you get a chance.

I had a random reboot last nite. 1st time in a while tho. Running deck 1.3b2. Think it was caused by the undervolt tho cuz it happened when phone was just chilling on table. Got it down to 900. That's as low as I can go... hw 003

[EVO 4G Q&A, Help & Troubleshooting] Stovepipe:
Results...

Well, unfortunately, it worked too well...

The thermal compound did what it should, it pulled the heat off of the chips. This made for the phone to be completely stable... while it wasn't charging. I loaded tested the phone and it ran flawlessly.

BUT.. when charging, the battery gets warm... actually very warm. Whether it was the heat from the battery being transferred back to the chips or the chips simply couldn't cool at that point I don't know, but the phone rebooted constantly. Unplugging the charger cleared the condition after about 5 minutes.

Now, not to get too scientific, but many chargers (particularly car chargers) feed higher voltage than 5V to rapid charge the battery, which of course makes the battery hot, thus defeating the purpose of the thermal paste. I'd noticed that on USB from the PC, it may've rebooted once, but on the AC charger, it was looping like crazy.

Now, for people who keep multiple batteries or charge their phone while the phone's off, this would work beautifully.

Of course, this depends on how bad the phone's condition is, as well as the charger you use, and the state of your battery. As with all "patch jobs".. your mileage WILL vary.

If you guys still want pics, I'll be happy to take it apart and post them.

As an aside, I'm going to try something else.. I'd noticed the cpu and memory chips were BGA (surface mounted soldered chips). I'm going to try to heat them up to reflow them, in case they're not making a good connection. (This problem plagued HP laptops with BGA chips). Will keep you all apprised on that as well.

Why am I doing all of this?? Because I love my evo. I'd hate to scrap it, and I don't have warranty claim available to me. (Bought it on eBay). Besides, IF I actually do fix it, it'll be cool, and may help others here.
[EVO 4G Q&A, Help & Troubleshooting] Shammon:
I've been getting these random reboots since I installed the mikG 2.1 + 3.0 ROM my hw version is 002. starting to think its a kernel issue.. Mainly happens when I connect a charger or disconnect a charger...
[EVO 4G Q&A, Help & Troubleshooting] batman61:
It really hard to tell if we are all fighting the same problem, or several different problems with the same symptom. Here are my observations about the EVO 4G reboot problem on my phone:

I have tried stock Sprint ROM, CM7R1, CM7-nighty-180, MikFroyo, but the phone would still reboot.

The phone will go into a boot loop, with each reboot happening earlier in the boot processes. So it appears that less and less of the OS is getting loaded before the next reboot loop occurs.

The only way I can stop the boot loop is to remove the battery. After removing the battery, the only way I can get the phone to stay up and running is to immediately go into settings and disable data (Settings -> Wireless & networks -> Mobile Networks -> Data enabled)

If I leave the data disabled for a short period of time, then re-enable it, the phone will stay up and run fine, until I start using data again.

If I disable data and just use Wi-Fi, the phone will stay up fine and I have been able to use the phone for an extended period of time on Wi-Fi only without a reboot.

It just seems to be when I have data enabled, that after some amount of usage or time (really can't tell) the phone will start the reboot cycle.

I believe this started happening in June or July when Sprint delivered the first OTA 2.3 update.
[EVO 4G Q&A, Help & Troubleshooting] Zyzzx:
So you are saying that your situation may not be heat related?
[EVO 4G Q&A, Help & Troubleshooting] batman61:
Can't rule out heat, because using the wireless radios for data will generate a lot of heat.

Maybe using the Wi-Fi radios for data generates less heat.

One other observation. I do not remember the phone ever rebooting during a voice call.
[EVO 4G Q&A, Help & Troubleshooting] Zyzzx:
When it was happening to me, the phone only rebooted when I ended the call. Because of this, I thought it was a radio issue.
[EVO 4G Q&A, Help & Troubleshooting] batman61:
There is a widget named "Battery Monitor Widget" that records the temperature reading over time.

I just installed this and will use it to see what the temperature readings were before and at the next reboot.
[EVO 4G Q&A, Help & Troubleshooting] batman61:
Had my first reboot since turning on the temp monitor.

Just before the reboot, the temp was a little over 28.6C. Not very hot and the phone had been as high as 37C yesterday without a reboot.
[EVO 4G Q&A, Help & Troubleshooting] rwalkerfla:
OK here is something interesting and I have not seen one reply on this forum or any other form like it.

I have a HTC EVO flashed to METRO PCS. I bought it from this guy, and i tested it good before i bought it. It was not rebooting at all. So after spending 2 hours on the phone with the loser customer service at METRO PCS, someone finally got my phone activated on my account.

As soon as the woman activated the phone, I got the first reboot. It kept rebooting at the Red Circle Spin when you boot up. I thought it was something she did, come to find out this is a major problem. I did a hard reset, then was able to use my phone for a while, and then the reboots kept coming over and over again. After unchecking evertyhing in options, and dropping the display brigtness to 10%, I thought i had figured out it was a tempature problem, but still I got another reboot.

Finally, I put my old phone back on my account, as I'm ready to sell the HTV EVO.

What's my point in all this?

Before I added the phone to my account and had service on it, there was no reboots at all. Now that I have taken service off the HTC EVO, I'm getting no reboots at all. I'm testing it right now I'm using Youtube, Netflix, I even got the display all the way to 100% brightness, and I'm getting no reboots. I'm trying to make it reboot and I can't. I don't know for sure if this is a temp issue, but i have tried everything everyone else has, except removing service from the phone, and now I get no reboots at all.

Does anyone know why this may be?
[EVO 4G Q&A, Help & Troubleshooting] batman61:
rwalkerfla,

What you are describing is very similar to my experience when I disabled data over the wireless networks (3G) and only used Wi-Fi for data. When I did that, my EVO did not reboot.
[EVO 4G Q&A, Help & Troubleshooting] rwalkerfla:
Ok can you walk me through the instructions on how to do that? i will reactivate the phone and see if it reboots.

---------- Post added at 06:46 PM ---------- Previous post was at 05:47 PM ----------

OK I have shut off the mobile network for internet access which took away the 3G icon at the top bar. I'm now running test to see if it reboots. So far after an hour, its all good and I will mess with it all day today. I am going to keep wifi off all day also and will try wifi tonight and see what happens. I have the brightness way up, and everything possible checked and it still is not rebooting like usual. I seriously just believe the issue is when the phone is connected to the internet, but since everyone wants there phone connected to the internet, there not even thinking about this.
[EVO 4G Q&A, Help & Troubleshooting] rwalkerfla:
Ok so its a new day now, and here is what's going on with my EVO. Yesterday i uncheck the mobile network box in settings>wireless networks. I kept the internet disconnected for 24 hours and here are the results.

My phone rebooted only 1 time yesterday, but i think its because the battery was about to die.

I charged the battery completely overnight with the phone powered off, then this morning when i powered it on, it went into the reboot cycle, constantly rebooting at the red circle on startup.

Just as a reminder, i had everything running hard yesterday, including live wallpaper, brightness all the way up, and i used youtube a lot. I also had wifi on all day and night of course.

My conclusion is there may be a heat issue, but it only came 1 time this morning when i powered the phone after it charging all night. Today i will turn back on the mobile networks button to see if i get the constant reboots again which im sure i will.

Sprint confirms known hardware issue

Hi Forum,

I'm an EVO 4G user from release date. (Unsure if 003). Experienced the same symptoms as everyone else in this forum. Random reboots when using GPS, camera, installing apps, browsing web,etc. Two visits to the local Sprint store (22192 zip) resulted in phone being flashed and factory reset. No change.

After second visit, phone rebooted five times in less than an hour. Returned to store. Tech asked me if it still rebooted. I said yes. Sprint ordered a replacement -- AT NO COST. They said the random and frequent reboots are a known issue.

I do not have hardware protection or any insurance plan with Sprint. Replacement phone will arrive on Monday after 4pm.

Hope this helps. Thanks to the forum for all the troubleshooting tips!

[EVO 4G Q&A, Help & Troubleshooting] trindy:
My phone has rebooted itself in the middle of a call several times. Just today while I was on the phone with my son. I had to pull over to pull the battery.

It rebooted itself last night while walking the dog listening to Audible.

The phone doesn't get hot. I have tried Aggressive Freedom, More Freedom. Stock Freedom. & Chop Suey. I have also tried all of the setcpu options on each of them. I don't use profiles or change the default min/max settings. I can say that it happens less using InteractiveX but that might just be my imagination.

I just flashed the stock kernel so we'll see what that does.

I can also say that this is a relatively new thing. I don't remember this happening before.
[EVO 4G Q&A, Help & Troubleshooting] xredgambit:
Mine random'y shuts down. But the deal with mine is when I power it up there is little to no charge left so it shuts back down. If I power it on when it i plugged in it will normally show a battery level of like 60% or more if my battery started out higher then that. Sometimes it will boot up like the battery is completely dead though. I think mine might be battery related though.

Same problem here. I get random reboots on 3G, especially using Google Maps, but it even happens with GPS off so I don't think GPS is it. I can't get it to reboot when on Wifi.
[EVO 4G Q&A, Help & Troubleshooting] ReppinTheSouth:
Ok. I'm posting for 2 reasons. 1) I don't have enough posts to post in the development section and I need to ask something about CM7. 2) I had this problem in the past (my posts are about 4 or 5 pages back). Bottom line is if you are having this problem, flash to stock, unroot, and take your phone to Sprint. You shouldn't have to turn off GPS when doing certain things or not use the auto brightness feature. The phone should work as advertised. If you think it's because of being rooted or you're undervolting or overclocking your phone, then reverse what you're doing and test it. I had the problem, took it to sprint, got a new phone, loaded my nandroid of my old set up, and haven't had any problems. Root cause = bad phone.

[EVO 4G Q&A, Help & Troubleshooting] sergioartinano:
Htc evo reboots

I have the same problem as everybody else the phone is reseting every 5 - 10 minutes

So what I have noticed is that if you turn on the phone after a reboot and then you activate the AIRPLANE mode and do NOT turn on the WIFI, the phone stops the reboot.

I believe the problem is related to the network part of the phone and at least in my case with this test I can be sure it is not the SD or heating problem... I left my phone with an application running for 20 hours and when I saw it again the same application was open. So no reboots

If someone with the problem could repeat this simple test, maybe we could discard all the other theories...
