Help Evo Rebooting on its own

the only reboot issue I know of on the evo is when the memory is tapped out and you try to use the phone for something...

We've also verified:
  • Reboot tied to tangled GPS hash tables, not hard reset fixable, previously fixable by HTC-approved GPSCLRX, but now mysteriously disavowed by both Sprint and HTC
  • Reboot due to overheating
  • Reboot due to defective battery
  • Reboot due to tangled caches and data caused by app and OTA update combinations, fixed by hard reset
  • Reboot due to mysteriously bad hardware - just a weak solder joint can cause this one, for example
  • Reboot during recharge / data xfer traced to defective USB cable
 
I recently posted that my evo would reboot while watching youtube or flash but it started happening while just using the net too. Someone mentioned try staying on wifi instead of 3g. Haven't had a reboot since.! :) just sucks that when I'm out with friends, there's always that chance it'll reboot on its own... :/
 
There have been many discussions about the EVO rebooting under various circumstances. I have experienced this multiple times on my EVO as well (hardware version 3). It appears that I've resolved 2 of the conditions that have caused these reboots.

In the first condition, my phone would reboot every time I'd turn off and exit my Toyota Venza. Obviously this is a bluetooth issue. However, since it used to work without a problem, it can't be solely a hardware issue. The fix for this turned out to be fairly well publicized by Vlingo. While the problem is associated with the use of Vlingo, it appears it isn't caused by Vlingo. Vlingo brings out a flaw in Android 2.2 which is documented by Google and appears to be have been fixed in Android v2.2.1, which of course we don't have on the EVO. In Vlingo, under the Advanced Settings, there is an option to "listen over bluetooth." If this option is checked, my EVO will reboot every single time I turn my Toyota Venza off and the phone disconnects from the Toyota bluetooth. Every time. If you turn off this setting in Vlingo, the problem goes away.

The second condition appeared much more randomly but over time I figured out a pattern. While driving, if I received a call that I answered over bluetooth, at some point into the conversation the phone would immediately reboot. It wasn't immediately, as I could regularly complete short phone calls without issue. The reboot would occur several minutes into the phone call. However, on some occasions, I could carry on long conversations without it rebooting also. Over time, I determined that I had to be running Google Navigation in order to experience the reboot problem. I don't think this is related to the Google Navigation software, but rather, I'd guess it is related to the use of the GPS itself. Once I suspected that, I could reproduce that every time I was using the GPS and received a call over bluetooth, several minutes into the call the phone would reboot. This one was a little tougher to solve.

There is a great app for Android called Tasker. I have no connection to app at all other than being a satisfied customer. Tasker lets you do some amazing customization and "macros" on your phone. To solve the reboot problem above, I used Tasker and did the following. I monitored the offhook status of the phone. When the phone goes offhook, I disable the GPS and close Google Navigation. When the phone offhook condition clears, I then restart the GPS and open Google Navigation. Google Navigation picks up where I left off. Since I've set this up in Tasker, I've had no reboots at all.

Perhaps someone at Sprint, HTC or Google can use this to get this reboot problem solved.


The bluetooth and GPS is exactly the only combination that has caused a reboot for me. I also use tasker and will try your solution for giggles and grins.
 
As you'll notice from my post at the top of this page - the problem's multi-dimensional.

I can't claim to know if another hard reset will help or not - but it couldn't hurt, and you'll want to try everything before having to get a phone swapped under warranty or insurance, in my opinion.

There have been several - not a large percentage, but several - people reporting that a hard reset (not working) followed by an update or s/w change (such as app changes) followed by a second hard reset will work.

When there's a pernicious problem - you just can't be sure without trying fixes reported to work for some others.

Sorry - can't guarantee either way, though.
 
I'm beginning to think my problem may be heat related. Yesterday while on a 2 hour trip using GPS navigation it rebooted without being on the phone. Blue tooth was enabled and paired with headset but not being used. The phone was charging on ac via an inverter and laying face up on a leather seat. After an excessively long reboot the battery was showing 106.5 degrees.

On the return trip I made some calls using blue tooth and using GPS navigation without charging and did not have any reboots.

Makes me wonder how clean the power is on that inverter.
 
My evo kept randomly rebooting and after trying everything under the sun, they determined that the phone kept killing the battery thus causing the rebooting? Anyone heard of this?

Update, today I had my phone on the same inverter and it had been sitting idle for over an hour mounted in a RAM mount so there was plenty of air circulation around it. Should not have been a heating issue. I got back into my vehicle and hit a program that launched the GPS and it immediately rebooted.
 
Well, fwiw: I tried it. It didn't work. It rebooted in the middle of restoring backed up settings, which caused a new and even more exciting set of problems. Fun! Oh well. Good thing I enjoy troubleshooting.
 
Another update, based on what happened today I am convinced at least in my situation it is heat related. Had the phone in my truck with the heater on and the damn thing rebooted 9 times this morning, often with no GPS or phone activity. I have never had this much continuous rebooting. It is also the first time I have the heat on in my truck this year. It also rebooted whether or not it was charging via the inverter.

Late in the day it warmed up so I turned of the heater and never had a rebbot issue again. The highest I saw the battery temp was 119.6. Late in the day when the problem went away the battery temp was hovering around 100.

I am wondering if there is in fact a heat sensor in the phone that will cause a reboot/shutdown and if so is it defective or just doing its job and at what temp does it activate.

Absolutely, all decent portables (maybe just all?) do carry thermal shutdown systems, no question. If you've ever seen a lithium-anything battery catch fire, it's astounding - I ignited one purposely under laboratory conditions and it was a regular blowtorch.

I tend to trust more that report you posted of your phone hitting 106 - my did that thermal-shutdown once on a black leather seat in the New Mexico sun, so I avoided that and no probs from then on.

And, for the most part, my phone's always under 100 - so - I'd question what's causing the temperature, more than the sensor.

If the battery's getting flakey - it can and will overheat more rapidly. In fact, the more a battery's been thermally stressed, the more likely this is - as I understand it, it has to do with detailed metal, tube-like structures within it getting deformed.

No chance you have a spare battery to test out?

No but I think I'll buy one for just this purpose.
 
Ive tried the hard reset and it didnt work. I have noticed that my phone shuts off once it gets over 100 degrees, ive seen it get to 104 once it turns back on so im sure its at a higher temp when it turns off. I can text fine but once i get on the browser,youtube,navigation or play any games thats when it reboots. Ill be visiting the sprint store and getting me a new phone.
 
I know it's frustrating for folks when they try my reset advice and it doesn't work.

I hope that you'll keep faith in me and my advice in general because of the first post on this page - a reset is one tool in the arsenal of knowledge against a number of known causes for this issue.

The phone's not defective by design, there are a lot of them out there - and like any product, some fail. I don't like it, I don't excuse and I know how it feels to be stuck - I really, really do.

The known cases of a reset fixing things saved those folks a trip to the store/warranty center.

If you've tried it and it's still failed - well - you had the gumption to try it, and my hat's off to you for the effort.

I've been slow to get back here because my mod duties keep me kinda busy.

I'm never ducking and running - just wanted to put that out there.

OK - what you're describing I'd attribute to three possibilites:

  • too many apps (so tell me if you have like 50 or more you've added, I have no clue what the magic number is - but it exists)
  • a bad update image
  • sadness - bad hardware

If you think it's a case of too many apps, see this advice:
http://androidforums.com/android-lounge/241768-few-new-user-frustrations.html#post2035102

Yes, it's for a different HTC phone, but I wrang out the procedures with another Evo user - so ignore the part about the differences to the Evo. And yes - start off with another hard reset, then check that advice.

If it's a bad update, you may be able to re-update, here's how:

  • hard reset
  • manually update
  • hard reset
  • then restore your stuff
Here's where to get the zip image of the latest instructions and how to install -

EVO update 3.70.651.1 pushing out now! - Android Forums

Do NOT let your browser expand the zip file - just save it to disk.

That note about not renaming to update.zip.zip - depending on your file explorer config, the ".zip" part can be hidden. Renaming this .zip.zip is the number one mistake.

The root of your SD card means the top-level - not inside any folders.

Hope this helps.

In no way it is your fault, you are being more than helpful with suggestions, thats what we are here for :) Thank you for your efforts and help!
 
Loving the phone so far but starting about a day ago it has been rebooting on its own randomly while im not even using it. Once rebooted 6x in 1 1/2 hrs.

I'm not sure if this is on topic but, HTC Sense was rebooting like on me yesterday. So bad that it was lagging when trying to make calls. I pulled the battery and it was still rebooting and moving extremely slow. I eventually did a hard reset and it is working just fine. I have to say every time I start messing with XDA stuff, my phone go's crazy in a day or two after I installed something from that website. And I also try and keep the applications down to a minimum. I try to keep at least 130 MB of Internal Memory.
 
No worries re: response time. You're not obligated to fix my phone for me. Sprint should be, but since it refuses to reboot under their roof, I can't get much help from them.

Sadly, the manual update did not work. Again, it's rebooting in the middle of restoring stuff. Boo. But it sure was fun! That was new stuff to me.

My hope is that this time it's bad enough that I can get it to happen at the Sprint store and they will give me a new phone. I have sneaking suspicions that it's heat related (although a very low temp is triggering it), and new hardware is in order. If I learn anything new I'll update.
 
I will say since the update a few days ago, I havent experienced any reboots, and I was averaging 3-5 reboots daily! so far its good, wish me luck.. Rebooting phone is a pain and had me very frustrated. Im on my 7th EVO because sprint gives you refurbed phones.. but if its a multiple device, the multiple devices department can give you a brand new one.. I think normally after 4 or 5
 
...I have sneaking suspicions that it's heat related (although a very low temp is triggering it), and new hardware is in order. If I learn anything new I'll update.

Then, there is the possibility that it is heat related and a hundred new phones will behave the same way if it hits the same temperature. Maybe you should remove the phone from the heat source?

With all these different vectors to the reboot problem it's tough to know how to solve any particular situation.
 
My EVO is also rebooting. I have only had it for a couple of days. The first was before I downloaded any apps at all.

I have noticed that there is one particular place on the Interstate, that if I am using Nav and talking on the phone, it will ALWAYs reboot. It is predictable. Other than that it seems random.

This is very frustrating. It will happen just after leaving the house with a freshly charged battery and this is Wisconsin in winter, so heat is not a problem.
 
Welcome to the forums!

That's odd that you're able to tie it to a particular function - and interesting.

Just for the record, please go to home screen, menu -> settings -> about phone -> software info and tell us the first three digits of your build number - like, 3.29, 3.70 - thanks.
