I believe it's definitely a hardware issue. I got my evo a week after launch and have hardware 0003. My girlfriend got the white evo a month after launch, or something.g like that. Hardware 0003 for her as well. I set her phone up identical to mine, as far as settings go. She started getting random reboots about a month after she got it. I have never (knocking on wood) had one, to this day. I've been rooted for months, and never had it happen, stock or rooted. I use my phone a lot,ad multitask a lot. My girl is a very very light user, and it happens to her weekly, usually when the phones just sitting there. Conclusion: faulty hardware of some sort

Rebooting Evo

I finally found a way to reproduce the problem on mine. After "warming up" by doing just about anything for 1/2 an hour, running Sprint Nav, Google Nav, and browsing the internet would cause it to happen. I took it to the Sprint Repair store and 4 hours later went to pick it up. They confirmed that they saw it reboot by itself, and said I should have a new one delivered to my door on Tuesday along with a package to send back my old one.

For those who are interested, I undid my S-OFF and installed stock software before taking it in. I didn't have insurance so they made me pay $35. I took it in "warmed up".
[EVO 4G Q&A, Help & Troubleshooting] akirasoft:
so there is no option for an immediate replacement? Fastest replacement is a 3 day via sprint for $35? This has basically gotten to the point where im getting 3-6 of them per day. Per other folks' assessments this is something that will get perpetually worse until the phone is no longer usable?

just some food for thought, I have two friends that bought the phone launch day that have not had any problems whatsoever. It might be more prevalent with later minor hardware revisions?
[EVO 4G Q&A, Help & Troubleshooting] notasimpleway:
I ran the RUU 2.29 a few days ago to see if that would correct the problem of my phone rebooting. It didn't. So I took it to Sprint. The tech said the diagnostics program they use found corrupted files on my phone so they did a "software refresh" on my phone. It worked. However, I forgot to ask him which files. But apparently it is files that the RUU doesn't touch. So, thinking my phone is back to running correctly, I decide to root it again and put a new ROM on it...The joke was on me. The reboots came back. I even made sure I downloaded new stuff so that I knew the rooting process was not corrupted. Does anyone know what could possibly be corrupted that the RUU wouldn't fix? And why it keeps getting corrupted? I guess I'm going to drive an hour tomorrow back to the Sprint store to find out what files are being messed up and to get them to correct it again. Does anyone know of a way to see which files are corrupted?
[EVO 4G Q&A, Help & Troubleshooting] tauzins:
mines starting to do this... i have no idea why also... more frequently too... its getting annoying, but i dont wanna replace my phone... anyone figuire anything out?
[EVO 4G Q&A, Help & Troubleshooting] Kenric:
Mine isn't so bad I can't live with it for a few days, but it is annoying enough I wanted to get it fixed. I was actually happy with $35 and a few days. I remember it rebooting by itself shortly after I got it during a phone call, but I also remember it getting very hot. Now days it doesn't get very hot before it reboots.
[EVO 4G Q&A, Help & Troubleshooting] teddyh2o:
Does anybody know if i can get the replacement (not immediately) even though i got my phone from the Google IO event?

I just talked to HTC. They said up to 50C is fine for a battery.

Mine reboots when it gets to about 36C or a little above. They told me it should not be rebooting at that temperature, but it seems something is telling it that that is too hot.
[EVO 4G Q&A, Help & Troubleshooting] TheDave1022:
Do we know if certain roms reboot more than others?

I'm on CM 6.1 Nightly 160 and I dont think I have ever had this many reboots. My phone was being fixed for 2 weeks and just got it back yesterday. Prior to this nightly, I rebooted, but never this much. May flash back or try another rom for a few days to see if it's the same now. (Got a new screen - Epson from Nova)
[EVO 4G Q&A, Help & Troubleshooting] TheDave1022:
About 99% of the time, my reboots happen when my phone is in Landscape mode. If I have the phone docked for navigation, normally about 15-20 minutes into my trip it will auto reboot. Sometimes it's fine until I try to go out of the nav screen and into something else. Today I was fine until I hit Home key and it rebooted. I ended up having to pull battery as it was boot loop.

Yesterday I was watching slingbox while walking around and had it reboot as well.

I have had random reboots before rooting with sense. Just a lot more frequent now. I can get it to reboot just about every day. My guess is it happens when the phone starts to get hot as someone else said.

I use launcher pro with auto-rotation off

I use CM with Accelerometer rotation set to 90 and 270 degrees

Not sure if that has anything to do with it.

Edit: On the 160 Nightly of CM6.1, I am getting reboots every hour at least in landscape and portrait. Not sure if there are roms that reboot more frequent then others. I am going to try a different rom and see if I get similar behavior.
[EVO 4G Q&A, Help & Troubleshooting] BB15:
If the phone is still under warranty Sprint should be able to get you a replacement (if they can't fix it). It doesn't matter where you got the phone, the warranty is through HTC, which is where Sprint is going to send it.
[EVO 4G Q&A, Help & Troubleshooting] teddyh2o:
Time to unroot my phone!
[EVO 4G Q&A, Help & Troubleshooting] BB15:
I'm about to unroot also. I just can't deal with this thing rebooting whenever I try to do anything other than normal phone stuff. Kinda defeats the purpose of having a phone with all of the capabilities these phones do if you can't use any of it.

I called Sprint last night and they said the issue wasn't on their "known issue" list so either HTC isn't acknowledging it or the issue isn't as common as it would appear based on this thread.
[EVO 4G Q&A, Help & Troubleshooting] roygbiver:
I am having this problem with the HTC evo i bought on ebay, new, and received on nov 1.

When it gets to about 96-98F it reboots. It gets to this temperature, usually, when using angry birds for too long, sprint gps too long, etc.

With other things, it doesn't seem to happen.

I also have a gel case. I rooted with unrevoked3.

I have tried two different batteries. I'm not sure what to do? I am talking with HTC about it now, but I don't know if it's a problem with many that will not get fixed by changing out the phone, and I also hate to send my phone in.
[EVO 4G Q&A, Help & Troubleshooting] teddyh2o:
My reboot restarted with my seidio 3500 mah battery. I thought it was battery problem so I switched back to stock battery and the reboot still occurred. I don't think it is the battery issue.
[EVO 4G Q&A, Help & Troubleshooting] BB15:
Has anyone tried resetting their GPS by punching ##GPSCLRX# into the dialer? I have seen posts in other forums that the issue may be related to a GPS issue.

Just for curiosity's sake I ran a log cat and proceeded to try and crash the phone playing Flick Kick (I knew that it has crashed before while playing this game). After a couple of minutes I got the following log entry just before my phone rebooted.

It looks as though the action of my phone trying to fetch my geolocation caused the reset. I'm going to try a few more tests to see if I can reproduce this, or see if I can get another result to crash the phone (non-GPS related).
[EVO 4G Q&A, Help & Troubleshooting] TheDave1022:
I turned GPS off, went into Pulse News (Just downloaded today since it went free), and I can get crashes after about a minute of using it. On CM and EViO
[EVO 4G Q&A, Help & Troubleshooting] BB15:
Well, now I'm beginning to think it may have something to do with the SD card (as some have posted in various forums).

I did a full wipe and loaded Fresh Rom so I could try the GPS fix, but it reboots as soon as it goes to "preparing SD card". I saved all my files and formatted the card and got the same issue.

I'm seriously starting to get a little pissed. :p
[EVO 4G Q&A, Help & Troubleshooting] tauzins:
according to that it looks like radio?

possible that low signal causes our reboots? thats when my phone usually reboots during a low signal area...
[EVO 4G Q&A, Help & Troubleshooting] BB15:
It's starting to look like there are more than one cause to this issue. I personally have never noticed any reboots seemingly due to bad reception. I can make my phone crash whenever I want by starting up a graphic intensive game, GPS, or anything else that taxes the phone.
[EVO 4G Q&A, Help & Troubleshooting] agilevic:
Should they recall it?

Phone will go into reboot loop if it is hot but may to one time reboot in just about any situation. Location searching seems to have something to do with that so I disabled it in Settings/Location/Off to see if it helps but too early to tell.

Basically my solution has been to keep all radios except for the phone off most of the time. Reboots are less frequent then and the battery life is great. That said for the price of the device and the cost of the plan in my view Sprint and HTC are not keeping to their end of the deal. If you want to be reachable by IM or VOIP or even just need constant email - the phone is not suited for that at all.
[EVO 4G Q&A, Help & Troubleshooting] BB15:
Just a quick update. I tried the ##GPSCLRX# fix and have yet to have my phone reboot today. I can't say for sure that this "fixed" the problem, but it seems to at least have helped.

Edit to add:

1) Go to dialer and punch in ##GPSCLRX# (must be on a non-AOSP ROM)

2) Enter your MSL (no need to contact Sprint for this, just install 'MSL Reader' for free from the Market)

3) Let phone reboot
[EVO 4G Q&A, Help & Troubleshooting] TheDave1022:
I may have to give this a try if you dont have any issues. I can pretty much get a reboot every time I use Navigation within my 30 minute drive.
[EVO 4G Q&A, Help & Troubleshooting] BB15:
Doesn't hurt to give it a shot. I believe it just clears out your GPS data. I've double-checked that my GPS is working flawlessly. Still no reboots.
[EVO 4G Q&A, Help & Troubleshooting] TheDave1022:
Seems that did nothing. I assume clearing the GPS out would work if I flashed back to another rom. Got a reboot as soon as CM came back up, and again a min after unlocking the screen.

Edit: Reboots during navigation as well, so didnt work
[EVO 4G Q&A, Help & Troubleshooting] BB15:
Well, I've had three reboots in the last hour, so I guess it was wishful thinking that the GPS fix worked.

Guess I'll be calling HTC again tomorrow.

HI EVERYONE

I WILL DEFINATELY BE WATCHING THIS THREAD

heres my story. i rooted my phone two days after getting it, i've had it for like at least 5 months. in the last month i have CONSTANTLY no matter what kernel, settings wiped, rom used getting reboots. very very annoying, ESPECIALLY during GPS NAV. not with just maps on tho

i have some info tho.. i took my phone to the sprint store, of course after flashing back to 2.1update1 stock and installing a few things, told him my issues, and he simply did a data reset.. the one in settings > SD and Phone storage > factory data reset

i know this sounds crazy but after he did this, i pretty much rooted again, and used a nandroid backup of my virus rom and its been working! i have had one random reboot in the last day since i have taken it to the store and watched him do this..

i know this is a long shot, but its been great. like seriously tho, i would wipe dalvik, system, cache, anything you can think of thats obvious in clockwork and i would get this as soon as i flashed a different rom or anything

EXTREMELY FRUSTRATING but for the past two days. my phones been SOLID.

try what he did for me and let me know what you think..

stick together folks, there is probably a common problem and we all can provide data and logs to make this be fixed once and for all!!!!!
[EVO 4G Q&A, Help & Troubleshooting] huckyourmeat:
FYI, just talked to HTC and the person I talked to said that it is a known issue. That's the first time that I read or heard that it's been identified, so I thought I would post.

He had me do a hard reset by powering the phone off, holding down the volume down button while pressing the power button, and then selecting "clear storage".

Just did that a few minutes ago. I'll update whether or not that works.

First post, but I've been following this and other reboot threads for a while.
[EVO 4G Q&A, Help & Troubleshooting] huckyourmeat:
Well, that was fast. Five minutes in, and I'm stuck in a reboot loop. Awesome.

Keep calling HTC, folks. That's the only way to get this fixed. Just to repeat from the earlier post, HTC tech support phone number is 1-866-449-8358.
[EVO 4G Q&A, Help & Troubleshooting] notasimpleway:
Hard resets have done nothing for me. That's what the Sprint tech kept trying to do earlier this week. I told him that I have tried several times and it hasn't worked and that his attempts to do the same would fail. So, he ordered me another phone. Should be here today.
[EVO 4G Q&A, Help & Troubleshooting] huckyourmeat:
Yeah, I wasn't optimistic about it. I was happy, though, to see that at least one person at HTC is now admitting that it is a known issue.
[EVO 4G Q&A, Help & Troubleshooting] TheDave1022:
Does anyone know what the bestbuy policy is for this? I have blacktie, but I dont want them to send my phone out for another 2-4 weeks.

I also have the issue where I can only get the random reboot during GPS, and seems to be only while I drive. So how would I prove to them that it's randomly rebooting? I would have to pretty much sit there for a while trying sling and whatever else to get it to reboot.
[EVO 4G Q&A, Help & Troubleshooting] BB15:
Do you have any graphic intensive games? I can get my phone to crash without fail while playing Flick Kick. Give that a try.
[EVO 4G Q&A, Help & Troubleshooting] k2buckley:
I don't understand how HTC doesn't recognize this as a known issue, and have a fix. I've been reading threads on this since the phone launched, and trying to find an answer. Everyone seems to think excess heat causes this, but I don't know if I'm sold on that. My phone runs at up to 49 degrees C (tethering with 4G while charging) and has never had a reboot ( girlfriends Evo has the reboot issue, not me) my girls will do it completely random, whether she has the phone in use or in her purse. I factory reset her phone a couple times, and left it COMPLETELY stock the last time, don't add one single app. It rebooted within a day. I think some evos are simply defective, one way or another. To Sprint we will go.
[EVO 4G Q&A, Help & Troubleshooting] huckyourmeat:
Yeah, I don't think it's heat, either. I haven't checked temperature, but after a hard reboot, no apps installed, all radios other than 3g turned off, sync off, etc., by phone rebooted sitting on my desk 4 times. Used the android task manager to see what was running, and there was some standard stuff running but it all appeared to be background.

My replacement phone is actually way worse than my old phone which is heavily used, lots of apps, etc.
[EVO 4G Q&A, Help & Troubleshooting] stinkfist1:
Got fed up with my phone rebooting, so i decided to unroot so i could return it to sprint. In the process my phone decided to start rebooting yay lol

[EVO 4G Q&A, Help & Troubleshooting] bignibb:
My phone would do this as well, I found that it was due to my battery, I was running a seidio 1750 battery and when I switched back to the stock battery no more reboots, I have since bought a 2600 extended battery and still no reboots. Might be an excuse for some to get a new battery!
[EVO 4G Q&A, Help & Troubleshooting] tauzins:
Hmm what was wrong with battery
[EVO 4G Q&A, Help & Troubleshooting] normntaz:
I have the Best Buy Black Tie Protection for my EVO. I took my phone in with the complaint of the random reboots, and also added a complaint about dead pixels, screen separation and light leakage from the bottom buttons (and around the edge of the screen). I only added the screen stuff, while legitimate, to encourage them to decide on a replacement.

I got the phone back about 2 1/2 weeks later, and the tech notes were "dropped calls: we resoldered your signal component". That was it. no mention of random reboots, and no mention (and nothing done) about the screen issues. Within 3 hours of getting the phone back, it was rebooting again.

I took the phone back to Best Buy. They said that all they could do was send it back with an Escalation. That was this past Sunday, so we'll see what happens.

I really wish I had gone with the Sprint TEP plan or with a Squaretrade plan, but the Black Tie plan might be worth it if I have to take it in for a fourth time because then they will replace it with another model (Epic 4G, maybe?)

At first I thought mine was GPS Related, but it now appears to be heat-related. In order to make it reboot when I took it in, I would drive to the Store with the phone in front of the heater. Then all I had to do was launch Google Earth, and spin the globe, and it would reboot within seconds. I would walk in the store and just lay it down on the counter while it was stuck in the loop. The last time I took it in, I didn't bother, however. The Best Buy where I took my phone in, the mobile guys don't look at or even try to troubleshoot the phone. They just send you to the Geek Squad counter and they write you up and send it out.

I have a Launch-day EVO with hardware version 002. I was running with the unrevoked s-off mod, Clockwork Recovery, and stock rom when I started getting the reboots. The first time I took the phone in, I just set the s-on. This last time, I ran the ruu utility to get the phone totally back to factory stock. Even at factory stock, the reboots were happening.

Of course it is scary when I hear that people's replacement phones are also having the reboot problem. I don't want to have to invoke the Black Tie's Lemon clause unless Sprint starts carrying the Epic 4g without the slider keyboard.
[EVO 4G Q&A, Help & Troubleshooting] TheDave1022:
I have the reboots with stock card and an after market. I did do a direct data copy to the new one though. Maybe something on the card is causing a problem. I can take my old card and wipe it off, and run off that for a bit and see.
[EVO 4G Q&A, Help & Troubleshooting] huckyourmeat:
I don't think it's the sd card. I've tried multiple cards in two different phones, both brand new, used, and new and used reformatted, and my phone behavior didn't change one bit.

In my mind, I've ruled out battery, all radios except maybe 3g, sd card, apps/software, updates, and use of the phone.

I've very easily gotten the phone to reboot (or I guess it did it on its own...) under various permutations of the above stated variables.
[EVO 4G Q&A, Help & Troubleshooting] jtom617:
wiped my sd card on my computer today then put back my rom files, music and pictures, i will report with results. today i had two reboots while in internet browser, out of no where, the 2nd did it on it's own without me EVEN touching it. then pulled sd card because i remembered someone said something and it didnt reboot again...

HRMMMMM

[EVO 4G Q&A, Help & Troubleshooting] rugalfury:
I def believe it is the sd card AREA. I left my all my sd cards out because I change from day to day for certain stuff. I used my evo without any sd card for about 3 days and I have gotten no reboots. I put back in my 16gb and in 4 hours a got the boot loop.

So did fixing SD card resolved the reboot issue?
[EVO 4G Q&A, Help & Troubleshooting] Asmodicus:
This has been happening to me a lot lately. Out of no where my Evo reboots. Sometimes it will do it over and over and sometimes it will reboot once and that will be it. I've tried switching batteries, taking out the sd card, and flashing various roms to fix the problem and nothing has worked so far. I do think it may be heat related because when it does go into a bootloop, it tends to get very warm. Sometimes I have to take the battery out and let it cool down before trying to boot up again. I took out my sd card, reformatted it, flashed a new rom and then put the sd card back in. It didn't reboot for a short time, but eventually did anyways. I hope this problem gets fixed soon.
