I'd be willing to bet they gave him a refurb. That seems to be the norm, 90% of the time.
[EVO 4G Q&A, Help & Troubleshooting] :
Yup a refurb. Pretty good condition too. If I hadn't checked the status I would've thought it was new. Should hold me over until I decide whether to stay with Sprint and get the EVO 3D when released or jump ship.

OK - I unrooted back to 2.1 which is where I started. Base 1.36.00.04.02. And loaded a few apps. Now I can't make it reboot. Go figure. I'm going to run it hard for the next couple of days and see if I can get it to reboot but it just makes me wonder. Some say it's definitely a hardware issue. Mine is 0003. I notice some of the apps I had with Mik's and Koni are missing but I'd expect that and the boot animation isn't the Sprint animation. I wonder what that's about. It just says HTC simply brilliant.

I'm wondering if I should flash the most recent firmware update. Isn't that 3.70. I can load that manually right? Same as unrooting. That will bring me to 2.2 Froyo right? If I do that can I flash back to 1.36? Isn't that a one way process. I'll still be able to root again right?
[EVO 4G Q&A, Help & Troubleshooting] k2buckley:
You could either run the most recent RUU, or you could take an OTA (over the air update) by simply goiing to menu>settings>system updates>HTC software updates (or maybe firmware update? I forget, but one of those two). That would bring you up to date.

My phone was having the ramdom reboots... the reboots increased every day that passed so I unrooted and took it to Sprint. They will replace my EVO with a refurb., no $$. I have the TEP.

I guess my question is: why I'm seeing people getting a refurb phone from Sprint and others getting a brand new phone from Sprint?
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
I think it may just be the whim of the sales rep that makes the call, also whatever they have in stock.
[EVO 4G Q&A, Help & Troubleshooting] cquinn:
A Question I asked Sprint when I called in and got an e ticket. i told them I wouldn't accept a used car as a replacement for a defective new car why should I accept a used phone. They just kept saying it's not our policy to replace with a new phone.
[EVO 4G Q&A, Help & Troubleshooting] :
I think it might also be how long youce had the phone. I bought mine first day it was released and got it exchanged about a week ago. Not really fair for me to expect a new phone when I've had mine for nine months.
[EVO 4G Q&A, Help & Troubleshooting] Mike Fitz:
Something odd that happened this past weekend, went an hour out of town to a cabin with my girlfriend (no, that's not the odd part...) and as soon as we got there and started unpacking my phone rebooted several times in a row, which had never happened and I've had it since launch day.

I had done the 3G trick earlier that day and thought I might have hosed something, I powered it off and pulled the battery for a minute, while waiting her EVO rebooted on it's own too. Mine is rooted and running SprintLovers, hers is a month old and unrooted. Reception was pretty spotty where we were so I started by turning off auto sync/background data and then the mobile network altogether.

As long as mobile network was turned off, both phones were fine but if I turned it back on to check e-mail or something on either phone it would reboot within a few minutes.

One we got back on the highway and headed home yesterday, turned mobile data back on and no further reboots.
[EVO 4G Q&A, Help & Troubleshooting] tryanDLS:
Reboots have gotten worse lately, so I bit the bullet and unrooted/returned to stock. Just for grins I played with the stock image for a while and it of course continued to reboot, proving that's it's not an issue with the ROM.

I took it into a Sprint store and asked them to run the mythical Slate test (which will probably cost $35 if you don't have insurance). Turns out that this test is really an automated program that runs thru a bunch of software functionality tests on the phone, it's not hardware test. My phone passed these tests, so the tech swapped batteries, which I knew wasn't an issue, since another Sprint store gave me a new battery to try a few days ago. He then took the phone apart to look at the circuit board. Turns out that once you take that cover off, there is a little pink/white checked litmus strip on the board next to the USB port. This is the same kind of strip you see on the bottom edge of the battery, opposite the pin connector. If the strip has started to turn white, it's an indication that water has gotten into the phone and caused issues. At this point Sprint stops looking for problems. If you have insurance, which I don't, they'll send it back to HTC, but HTC doesn't want to bother with phones that show evidence of water damage.

In my case, I don't know how water could have gotten in the phone. It's never been dropped in water or in the rain. The Sprint guy told me the biggest culprit for water damage was taking your phone in the bathroom while showering. The steam is enough to cause these problems. Once again, not an issue for me. I find it hard to believe that these phones are built to such low specs, given how much experience the hardware makers should now have with what people expose their phones to.

The upshot of all this is that the phone is now junk - Sprint wont do anything else. The option is to pay $499 for a new phone or add a 2nd line with a 2nd EVO for $199 plus the additional monthly fee and throw the old phone in a drawer. Then when your original 2 years is up, you cancel the first line.
[EVO 4G Q&A, Help & Troubleshooting] tryanDLS:
Following up to the above.

While adding the 2nd line saves you $300 ($499 list - $199 with rebate), it costs you an extra $50 a month (nice of them to not charge the $10 4g fee on the 2nd line). So it's still not a good deal.

The next thing to do is wait 30 days, then go and drop the 2nd line and pay the $200 ETF. Paying that sucks, but assuming that that you have significant time left on your original contract, it's cheaper than $50 x 12 or more months to keep a 2nd line that you wont use with a dead phone sitting in a drawer.

I actually tried to kill the 2nd line the day after adding, but Sprint wont let you keep your original number if you do that.

Could you give an update - Still no reboots?

[EVO 4G Q&A, Help & Troubleshooting] Mike Fitz:
Nope, neither of us has had a single reboot since returning to an area with service. Seems odd since I was out in area where I was going between roaming and no service today. Not sure what the difference was in the area where the reboots were happening.
[EVO 4G Q&A, Help & Troubleshooting] LittleWhiteCorvette:
Okie doke....so, i'm newly registered here, even though i've been reading the forums for awhile. Until this past Wednesday, I never had any issue with my Evo. I've had it since June. However, on Wed (and I believe this occured immediately after an auto update), I got a weird error/notification box that said something to the effect, that I may have trouble viewing streaming multimedia content, and that I should call Sprint to let them know this. So, I called. The CS rep said she would update profile, etc from her end. Well, after I got off that call, within just a few minutes, the phone rebooted while it was just sitting on the table. At first I figured it musta had something to do with Sprint updating it, so I wasn't too concerned. But, the next day, it rebooted MANY times. Didn't matter if I was using it, or an app or whatever. Also, a couple of times, when there would be an incoming call, it would ring once, maybe twice, and then there would be a sort of high pitched, constant buzzing sound, but otherwise frozen phone. I'd remove the battery to get it back up and running. Since then, the random reboots happen a little more each day. Although, I haven't experienced the high pitched buzzing/freeze in a few days now. I guess I'll hafta take it in and get a replacement too....seems the only way it's been able to be resolved.

Forgot to mention, that the error/alert I received that first day said "DRM notification; license required"...I only just recalled that, as it came up twice a bit ago while I was using the video camera. This seems to be the thing that started this whole mess for me.
[EVO 4G Q&A, Help & Troubleshooting] XsMagical:
My Wife's phone was doing the random reboot last week, She had hardware version 004. I took it back 2 days ago and got a new EVO Black, hardware version 004 and today it started doing the same thing. We used the SD card from the Old evo, could that be the problem? I really don't feel like taking it back today but if i do I think i will get her something else. My evo is hardware 003, rooted and has never had an issue.

Could be be the hardware version 004?
[EVO 4G Q&A, Help & Troubleshooting] ReppinTheSouth:
Let me add my sad story. I bought my phone used off of ebay in February. I started getting random reboots maybe a month or so ago. At first I thought it was from flashing a new ROM that maybe wasn't as "stable" as I thought. Fast forward to now and it's horrible. I first noticed it in navigation but now it's coming from everywhere. Sometimes I'm scared to touch the phone. I'm trying to avoid unrooting and taking it to Sprint but I do have insurance. This is what it's for so I will be taking it back to Sprint soon if need be.

Misery loves company. At first I thought it was just my phone but now I see it's a widespread issue.

Through some messing around I have done, my theory is it might be the SD card if not hardware. The one thing I want to add is make sure you a checking the card for errors and not just formatting it. I am going to try that when I get home using my SD card adapter and not the actual phone. If that works, I will be ecstatic.
[EVO 4G Q&A, Help & Troubleshooting] 27s:
It is a known issue in some evo's. If you run a stress benchmark, and it crashes (make sure you use a stock rom!) ...bring it by a sprint corporate store... they will replace it if they can replicate it...
[EVO 4G Q&A, Help & Troubleshooting] cb7tuner93:
I recently had mine replaced, Used same SD card I had in old one and no problems yet, Rooted it the same day I got it too. It seems also from Sprint repair center "bad memory blocks" or memory failure from too much wiping for us flashers,also if you've dropped the phone one BAD time or many times hardware gets loose inside or messed up processor. Also Logcat doesn't show errors from the reboots, HTC has to start dealing with this issue or Sprint has to get on HTC's case!!
[EVO 4G Q&A, Help & Troubleshooting] ReppinTheSouth:
Update. I unrooted last night, took it to the Sprint store, and it failed one of the diagnostic tests. I'm not sure which one but my replacement is in the mail.
[EVO 4G Q&A, Help & Troubleshooting] ryohei47:
mine has been restarting ever since i got it, getting progressively worse, changing roms and kernels didnt help. I have a idea tho. it seems like it restarts whenever it gets to 35 Celsius, i was watching the temperature closely, and it seems to always restart around 34ish. that would also explain why the reboots take a while to end, because the phone takes time to cool down. regardless, im gonna unroot and take the phone in to sprint tomorrow, gonna insist on a new phone, hopefully it works
[EVO 4G Q&A, Help & Troubleshooting] ReppinTheSouth:
At first I didn't think it was heat related. The only reason I say that is because I would get reboots before the phone felt hot. After getting my replacement, I think heat is probably the main contributor. My defective phone would get hot quick and it would cool down slowly. This phone doesn't get as hot and when it does get to the 38 - 40 degree celcius range, it cools down very quickly. A lot faster then my old phone. I don't know if there's a heat sink or what the phone uses to cool itself but it must be defective. It's a noticeable difference after getting a replacement.
[EVO 4G Q&A, Help & Troubleshooting] LittleWhiteCorvette:
Update...

Ok, so a week ago yesterday, I finally called Sprint, after trying EVERY idea that others suggested here and elsewhere. None of the "fixes" worked. As a matter of fact, my phone got worse everyday. Anyway, after explaining to tech support what the issue was, and that yes, I did take the battery out, etc. he said a replacement would be here in 2 biz days. Ok. Tuesday came and went, and no replacement. So, called Tuesday evening, had to explain much of what I had explained before all over again, even though the rep could see the eticket there. Anywhooo.....turned out, the first guy had, in fact, not put in an order for a replacement. Sooo, after the phone rebooting 4 times while I was on the call, a replacement was ordered. I was informed that the Evos were backordered, so it could be 10 days before I received it. Lo and behold though, yesterday the reppacement arrived! Not one reboot so far with the new one (refurb, not new new). However, when I am on a phone call, the speaker rattles in my ear. Not a really big deal for me right now, since it beats what had become about 30 reboots per day. Plus, I don't make very many calls anyway, and in July I can upgrade. So, I can definitely live with the rattle until then. Fingers crossed that this one makes it those two months!

overheatreboot

I have discovered the overheat reboot problem solution.

Go to Settings:

Go to Display:

Go to Brightness:

Uncheck Automatic Brightness:

or (Turn it off.)

This has solve all of my problems of the last 5 months.

I have test this fix for 4 days now. Phone works perfect.

[EVO 4G Q&A, Help & Troubleshooting] skywatcher49:
I have it.

The phone reboots when the display is set for auto brightness.

Go to Settings.

Go to Display.

Go to Brightness.

Turn off Auto Brightness.

Set the brightness at about 50 percent. Cool days allow more. Warm allows less.

Phone stays cool and never fails.

I have tested this for a week now.

This is the answer.

[EVO 4G Q&A, Help & Troubleshooting] bisby:
this didnt work at all for me. I have my phone set at 25% brightness always. I get 0 reboots when on WiFi. and constantly reboots on 3G.

If I disable GPS the bootloops slow down for a while, then return at normal speed. I usually wind up turning GPS back on later and it'll be fine for a while without any bootloops.

it seems like that playing games (like angry birds) will cause it to loop reboot on wifi.

My brother also claims he has random reboots with him phone from time to time.

His is the most recent sprint unrooted setup. Mine is CM7 (my problems started a while after i flashed CM7, his problems started roughly the same time, but clearly unrelated)

EDIT: taking out the battery and letting it cool off also seems to slow down the bootloops... usually after a reboot or two it gets stuck (or goes really slow) at the EVO 4g splash and i pull the battery anyway. Usually doesnt seem to be hot when it reboots the first time and sitting on the splash is when it starts to heat up.

Launched a game, let it sit for 5 minutes or so and it was fine. unplugged the phone and let it sit and it rebooted after a minute. on wifi.

Well after some tests, I know 35°, Is the killing point, once phone gets above 35° it bootloops until temp drops to 31° then phone boots right up an runs fine. What I am doing now is placing the phone on a ice pack, it runs perfectly until it gets to 35°, of course it can't ever heat up on ice pack I have to remove it from ice pack run some benchmarks to heat it up. Once phone starts bootlooping place it on ice pack with in a few seconds temp drops enough for phone to boot.

Well, I tried the sense rom I was trying after doing the partitioning and it didn't work. I loaded CM7, didn't work. I am going to try downgrading all my radios and what not and see what happens.
[EVO 4G Q&A, Help & Troubleshooting] Ice007112:
I am pretty sure this all comes down to a hardware issue. I have tried many different roms, setups, rooted, unrooted, batteries, app uninstall, reinstall, everything. I am thinking it may be similar to the earlier Xbox 360. Were the solder joints were done with a cheap solder that would crack and separate away from the board. The Evo doesn't have a temp sensor on the cpu. So it really doesn't just reboot at a certain temperature. A certain temperature may make the cpu or other piece of hardware come out of contact from the circuit board.

My phone has been doing this for about 2 months now. It wasn't so bad at first but now that summer is here and hotter days, it has become a nuisance. The past week the phone will also kick into car mode constantly. I got so fed up and just went to Sprint and showed them the problems. I lucked out big time. The distributor for the store I went to ran out of refurbished Evo's and I am actually going to get a brand new one sent to me on Monday.

As much as everyone would like to be able to fix this on their own, I believe it isn't going to happen. After months of trying every software based fix I possibly could find and do, it didn't fix the problem. If Sprint and HTC sees this overload of returned Evo's being brought in for this problem, then maybe it will be looked at as an actual problem that will be addressed. Until then, if no one does this, it will just look like user error or an app malfunction to them.
[EVO 4G Q&A, Help & Troubleshooting] Zyzzx:
Thanks for the reply, but, I got it up and running.

I was reading what you wrote and I just couldn't believe that was my scenario due to the fact that I had the issue and then I recovered from it.

I realized that the last thing that I did in my last scenario was load one of the HBOOTs, 0.97 to be exact, so I tried it again and now I am in and so far no issues. I will report back and let you know what is my outcome.

Just a brief what was happening this time, not a dang thing. It wouldn't get far enough for any user input except for in the recovery and now it seems stable with the newest nightly. I am either going to retrieve gapps and stick with cm7 or I will try to flash vr again without doing any radio updates.

My old Evo had constant rebooting and hanging at splashscreen, and and overheated to like 135 degrees Fahrenheit on standby, and once 145 while on the charger with stock kernel, so I took a screenshot, unrooted and took it to sprint.

The guy didn't run the test properly, I found out later, but I got a replacement battery. Problem persisted during the week, took it to Sprint, they ran tests and shipped me a new 0004 Evo. No reboot issues anymore. Hardware issue I guess, no kernel solved it for me
[EVO 4G Q&A, Help & Troubleshooting] Zyzzx:
Well so far so good, I am running again with no problems. I didn't have success right away after my previous post but now I officially have it working. I decided to upgrade the radio to the most current radio and booted the phone an everything was great except for one very important feature my cell phone must have, connection to a tower. So I rebooted and reinstalled the radio and all is working very well.

After this experience, I would say that you may need to reflash a radio if the outcome is less than functional.

Hope this helps others.

Thanks.

[UPDATE] Everything is going well with the phone, no reboots at all actually. I was able to flash the newest radios again and not have problems. I hope this helps others to fix potential reboot issues.

Also, just curious if anyone might know, what memory would bootlog uptime log be referring to with "lowmem"? Internal or external?
[EVO 4G Q&A, Help & Troubleshooting] jefferskn:
What specifically did you end up doing to fix your rebboot issue. What radio did you downgrade to until you could not get it to randomly reboot? I firmly believe it's a heat issue. If I put my EVO in front of the AC vent in my truck with the GPS on it won't reboot but if I just hold it it will reboot with GPS on after about 10 minutes. Also, any processor heavy actions will make it reboot after 5 minutes or so as well.
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
If you're over clocking, it can reboot, too under volted, it can reboot. If it consistently reboots while using gps, then it probably is getting too hot, as the device has a fail safe to reboot due to heat.
[EVO 4G Q&A, Help & Troubleshooting] Zyzzx:
My steps was to make sure the file on my PC was copied correctly using teracopy and then reflashed the same radio again. I believe that it "glitched" when I flashed it the first time. I was under the impression of overheating, but it would more often than reboot at the time the radios would initialize. The time before this, it would reboot during and after calls and off and on through data activities(market, synchronizations, etc. )

I can say it is definitely the CPU Temp.

35 Degrees C.

So Using SetCpu helps slow it down with these profiles...It doesn't however prevent it...I'm not sure why some phones heat up quicker than others...but mine does. The I'm not sure if this heat is being caused by external temps, battery temp, or dust....the only thin i can think of is something is either building up or slowly wearing out where the cpu is starting to heat up more rapidly...I;m going to buy some dust off, a new case and another battery to see if any of those 3 or the combination of is causing the phone to heat up which is causing the cpu to heat up.

I called Sprint today and told them that my Evo (out of warranty, I got the phone when it first came out) is constantly rebooting, using GPS or just browsing the internet.. the battery gets extremely hot and even with the latest gingerbread it still reboots.

My Evo has been rebooting seemingly randomly for about a month now. After the second time I started paying close attention to when it rebooted. What I noticed was that the reboots occurred when I was trying to download a bigger amount of data (anything bigger than text messages) with low signal it would reboot into a loop. To fix I have to take out the battery and take the SD card out and put it back in.

Not sure what could cause this. I have no issues when I'm on wifi (can watch full movies on Netflix while on wifi). It didn't start until I updated to Cyanogenmod 7.0.3.1. I tried going back to other versions of Cyanogenmod, but still had the reboots. Hoping that a new Cyanogen update to go along with the reason stock Evo update may solve the problem.
