My random reboot problem started several months ago. Seemingly tied in with the timing of the 2.3.3 update. At first I didn't notice it too much, thought maybe since the phone was slight older it was acting up. I got the white HTC loading screens randomly, random shut downs with battery dumps, while testing o would randomly be taken to the 1st text of a conversation, I had random contacts deleted (my own mother!).

Over time the random rebooted got into the 5-20 minute category. Every time!

My fixes:

1. keeping the phone tethered to a power source. Only unplugged long enough to travel to the next outlet/car charger. Phone maybe shut off once or twice that way (compared to hundreds untethered).

2. Airplane mode. The phone would stay on for hours if it was switched to airplane mode. It basically became an overpriced mp3 player for me considering thus was the only way to keep it running.

Finally took it to sprint a few weeks ago, for $30 they gave me a refurbished one. It worked fine seemingly... About 12 hours later, I had my first shut down. It only got worse since. I decided to root/rom the phone hoping it would help. Again.. the first 10-12 hours it seemed fine. But again, it started randomly shutting off/battery dumping.

I've just about had it. This phone was great! I had it for over a year without one complaint. Now 2 ruined phones in such a short timeframe... HTC can suck it.

I'm having the reboot problem as well. I like my HTC but if I can get a Motorola or Samsung that does not have this problem I'm going to dump HTC. HTC should stand behind their product, rooted or not.

my evo just updated to gingerbread after being of froyo and constant reboots on the white screen. Seems like I'm be busy tonight trying to fix my phone again.
[EVO 4G Q&A, Help & Troubleshooting] pdoxtader:
A little more info on this...

Bought my evo in Septenber of 2010, and it started rebooting about a month or two after that. Only Once in a while... never while I was using it. At first I actually thought it was Sprint, forcing a reboot after applying an OS patch.

Over the last couple of weeks, the rebooting has become horrible. It'll reboot while I'm trying to text, in the middle of a phone call, when I'm trying to make a phone call, when it's finished rebooting after it reboots... and it almost always goes into a reboot loop - forcing me to pull the battery, wait a minute, and try again... and hope it doesn't start looping again before I can even get into the phone.

I have a stupid ammount of texts on the phone (28,000 - no joke), so I assumed that was the problem, and I've been fighting the reboots while trying to remove them. Then I finally found this forum.

I'm posting this here because after reading through many of these posts I really think the guys who say that they have had success disabling wifi or 3g service are on to something. Myself, I noticed that my phone doesn't reboot at all when I'm in airplane mode. I can delete texts - which always causes a reboot after a few minutes (and this text purge will take hours or days - even with apps that claim to delete texts quickly).

In fact, if I'm in airplane mode for a while and I switch OUT of it and connect to the network, this usually causes a reboot. This gave me a hint. We know it's a hardware problem. I think it's a problem with one (or more) of the radios in the phone. Right now, I think it's the 3g radio. I don't live in an area that has 4g service, so I can't tell you anything about that one way or the other.

Taking a hint from my positive airplane mode experience, I disabled 3g and wifi for a while. I'm able to make calls, send texts (only sms - not mms), and the phone hasn't rebooted in about a day. I know that may not seem like much to you, but that's a HUGE improvement.

I don't have a replacement plan with Sprint. I'm sure I've had this phone for too long for anyone to be willing to replace it... and it's the only phone in my house, so I just can't wait two weeks (or even one) for a replacement to arrive.

So for now, until I can replace this thing, I'll just leave wifi and 3g off unless I absolutely need the internet - in which case I'll turn ONE of them on (wifi if it's available).

Sprint isn't going to fix this. They're just not going to use whatever hardware is causing the problem in the next generation of phone... so if you don't want to have to deal with this, get another MODEL. The evo is cool, but it's not worth this kind of headache. There are lots of android phones out there now - alot of them much better.
[EVO 4G Q&A, Help & Troubleshooting] hypn0toad:
I've got the same issues as everyone else here.

I had my first evo for about a year (june 2009 to apr 2010), and the problem eventually got so bad that I sent it back to HTC for an RMA. Sprint tech wasn't helpful. I restored my phone to factory defaults a couple times and it didn't fix anything.

My 2nd evo (april 2010 to present) was okay at first, but its getting worse and worse. It always happens as the phone is used more- GPS, whatever. I'd reaffirm everyone's observation that its overheating related (or mistakenly thinking that it is overheating).

Would a sprint store replace my phone? I'm way out of warranty though. It sounds like it is a hardware defect though..

I dont even know what to do anymore

I had the evo 4g since 2011 in the spring time.

I rooted it until i went to boost because sprint is about the $$$$$, then i decided i wanted a different ROM so i went from the CUIU to MIUI, but being cautious i did a nan-droid backup.

that was the last of the phone after that i flashed the ROM then i went to reboot, stupid phone would go into boot-loader every single time. so i said im going to get it back to stock. Did that now it restarts every 2-3 minutes.

I literally stayed up for 5 hours searching Google and XDA for a solution and found many different attempts but none work. And also the phone wont recognize my usb cable or any usb cable for that fact so i cant root it the nice way.

i don't know what to do, if anyone can shed any light on the situation it would be greatly appertained
[EVO 4G Q&A, Help & Troubleshooting] mpsantiago:
This sounds like a different issue, most likely something went wrong flashing the ROM. Did you do a full wipe before flashing? If not, do that. If you did, try going into recovery, wipe the cache/dalvik 3 times each, reflash your ROM, then run "fix permissions" from recovery.

Regardless, I think this is the wrong thread for your issue.
[EVO 4G Q&A, Help & Troubleshooting] rastaboi:
What thread do you suggest
[EVO 4G Q&A, Help & Troubleshooting] dogshed:
Fixed maybe

I didn't have time to be experimental so I just did everything anyone said might work.

My hypothesis is that a newer rom has some better battery management stuff in it maybe? and that erasing the battery information kept it from getting confused when I put in a different battery.

A few months ago I bought a new battery and that seemed to help, but I wonder if then swapping batteries that had been charged with an external charger confused it. Maybe battery information should be erased each time a battery is changed with an externally charged one.

I also wonder if maybe the newer rom has some better battery charging stuff in it.

I found I can get the boot menu if I hold the down volume key while inserting the battery. I erased all data (which may not have been necessary.) I erased both caches and the battery information. I installed this rom: ss_stock_4.67.651.zip

I had to reinsert the usb cable when the charge light went out a few times, but eventually it would stay on. I did try running GPS, WiFI and navigation and it did not reboot.

Maybe the battery information has nothing to do with it. This thread says the battery information isn't used for decisions about charging.

After more than 20 hours without a reboot I tried to send some text messages and got error code: 97 error class: 2

I dialed *2 and the yellow and black thing told me to do some kind of update.

It still wouldn't send text messages and then when I was using that yellow and black thing it started the reboot loop again.

It gets to the screen where you can slide down to unlock the phone and then it reboots.

One thing odd that I've noticed, but did not mention before is that when I use the volume down to get into the boot menu it won't take any commands and then runs hboot.

On that other website someone mentioned that having s=on while having a rooted kernel can cause reboots.

HTC Evo first running on Deck 1.3d and now running on Deck Reloaded reboots at random times while using Navigation system. So far experienced multiple reboots on Deck 1.3d while on a 90 mile trip. Phone rebooted several times during the trip at random times. On Deck Reloaded so far happened once, on short trip 10 miles, rebooted on the way back had no problems while doing the first leg of the trip getting there.

I'm using Deck Reloaded rom and everything was working fine until my battery died. Now when I try and turn it on, it constantly reboots. It gets as far as the lockscreen and thats it. This is driving me crazy, I tried using that battery calibration it came with that's why I let it drain, can that be the problem?

Turn off 4g

My HTC EVO 4g was rebooting at least once a day, sometimes in the middle of a phone call. I found that turning 4g off solved my problem. Since 4g drains the battery fast so, I really didn't have a problem with turning it off. Now I only turn it on when it suits me but I never leave it on. Try turning 4g off and see if the reboot problems goes away.
[EVO 4G Q&A, Help & Troubleshooting] Infinitizm:
if this is the case would it be possible to circumvent this altogether by using something along the lines of setcpu or cpu tuner for root to tell the phone to go into powersaving mode once it hits 35c, or actually I guess that would be something along the lines of 31-33c this way it never has the chance to reach the cut off temperature and doesn't throw itself into this reboot loop?

I myself just now started noticing that my phone would reboot itself as well. My temps are around the same during this period and the boots last FOREVERRR...or until I pull the battery:(

EDIT: For a few hours cpu tuner was able to keep the temperature down by disabing some things once it hit 33c. however, I plugged my phone in to charge and shortly after it hit 100% it went into a loop while still on the charger. So I feel as tho this has to be a temperature/battery related issue and not an issue of what rom/kernel/tweeks we are all using

Interesting. Mine started the first time on October 8th while also on a trip out of town.

From my understanding, I have 3 options.

Return using best buy crappy insurance - free - 30 days turn around

Return to HTC - free - 14 days turn around

Return to sprint - $35 - 3 days turn around
[EVO 4G Q&A, Help & Troubleshooting] normntaz:
Does exercising the HTC or Sprint option void the Best Buy insurance (That I presume you are paying $9.99/month for)?

It's kind of sad that the one that costs $120/year is also the slowest.

I have been having the same issue for a long time now. The first time I had it, I took it in (unrooted it first) and they did a Master Reset. Then I rerooted and set up my phone like I normally do and it worked for months. The other day, I upgraded to Fresh 3.4 and it started again. It seems to me that the overheating happens AFTER the rebooting issue starts. I never notice it overheating prior to the reboot.

As for causes, it seems really random. Last time I had the issue, I was able to narrow down the cause to the gps. Anytime I ran an app that used the gps, it would always reboot. This time, I can't narrow down the cause. However, I can reproduce the problem everytime when I attempt to connect to an enterprise secured wifi hotspot for the first time. Though it's not the only thing that causes reboots for me.

Could someone make a poll to find out how many are affected by the reboot issue?

I have had this problem with two different Evos. Both bought at the same time, 1 started having trouble within the first month and was completely stuck rebooting by about September 22nd. The other started acting up about 3 weeks ago. I sent it in to HTC before it got completely fried. A useful note, if you bought your phone before 10-25, Sprint will act as the warranter. If it is a warranty covered problem they will repair or exchange in store. The only downside is that this defect is a "board related issue" and Sprint can't fix that in store, so they exchange for a refurb. It's free if you have TEP and $35 without. Since HTC makes us pay for inbound shipping ($10) and a" $39 or less triage fee", that's still not a bad deal. Plus your phone is gone for ten days to two weeks.

Surf the web for an hour. For me it got worse and worse to where it would go into a reboot loop after 3-5 minutes of surfing the web.
[EVO 4G Q&A, Help & Troubleshooting] .jond:
It's definitely hardware. It reminds me of back when I overclocked by AMD PC years ago. It developed a random reboot issue after a year or so. It would reboot after it got a little hot. When I took the computer apart, I noticed the capacitors surrounding the processor had all popped and were leaking stuff out.

My guess is it's the same here. High heat causes the initial damage(capacitor or something to pop), and from there it starts to get worse and worse.

After I installed CM6.1 the issue started and it usually happens after I unplug the phone from charging be it car, outlet or PC.

Also if I have it in my pocket it happens. This phone is a new replacement I got 3 weeks ago. So this is a new Evo.

Going to try going back to Myns, and see if it still happens. Also, kinda glad I am not alone. Would be the third time I have to take my phone in xD

Looks like the incredible has the same problem. I wonder if it's all newer HTC phones?

"I can advise from personal experience on your symptoms that you have one choice ... Return to verizon for a refurb. This is what happens when you have an early incredible with a faulty hardware radio. It gets to the point where it starts trying to compensate and super heats. You must return.

Every other suggestion would be a mask to an existing well known hardware problem."

I have had this problem recently. It all started happening after applying the Battery Tweak. I uninstalling it and thought everything was cool. Kept happening. I then changed kernel thinking it was that. Still happened. I then went back to a nandroid before the tweak...still happened. Then I went back to an even further backup and still happening. The phone isn't even hot. I think it's hardware now. I had this phone since a month after release and it just now started doing this. Is the new insurance into effect? If so, can't I just return it and get an exchange? The warranty may not be good since I did buy this from someone and not "new". The rebooting is getting unbearable. It's happening almost anytime I tax the cpu. I really don't want to return it after I put all the work in to scraping the black off to make it red on the back. :(

Mine reboots from time to time, but I've always just blamed the nightly roms or experimental kernel's I tend to use. Or the fact that I use the 200dpi density, that sure seems to make launchers like to crash. In any case, it reboots way less than even a stock Palm Pre, so I'm happy enough. Although there was that one time where every time I was about to get 3 stars on Angry Birds on a hard level it would restart, now that was kind of infuriating. It does seem to be heat related on my phone most of the time though, I can usually feel that my kickstand is hot when it does reboot, and it sometimes will reboot again right after it restarts if I don't leave it alone for a while.

Stock, unrooted Evo - reboots progressively worse

I have had the EVO (s/n HT067HL07xxx) since July on Sprint network. The phone was never dropped or abused in any way; never rooted, never used with after market batteries. The reboots have been progressively more frequent and occur at very random situations (pretty much had all mentioned in this thread). After reboot the phone would typically go into a reboot until the battery is removed. I found I have to let it cool down.

Today I had all radios except for the phone turned off and was playing a game while in a moving car. The phone rebooted after about 20 minutes. As some other poster said this in my view points to hardware problem and most likely related to processor overheating or a faulty RAM.

I have yet to try the same with all radios off (airplane mode) in to completely eliminate any network related issue but I doubt that the CDMA network would be to blame for this.

Has anyone found the root cause of this problem? For the hackers here the serial number of my phone is

For those who got the replacement phone. Did this help? If your phone does not have the reboot problem, could you post your serial number here and how long have you been using it?

I started getting the infinite reboot loops mid october while running a version of fresh 3. Tried various methods to fix it including flashing different roms, different radio versions even changed from recovery managers from clockwork to amon's. I did a full data wipe before every change to no avail, the reboots just kept occurring.

Finally i said screw it and called the insurance company. Installed the latest version of fresh on it right away and its been perfect. It's so nice having a stable system again, those reboots were pissing me off
[EVO 4G Q&A, Help & Troubleshooting] frieked:
I had the random reboots starting a month or 2 ago. They slowly started happening more frequently until one day I couldn't get past the boot animation... I flashed different roms 2-3 times a week, sometimes more. I factory reset/unrooted and brought it to a sprint store where they replaced on the spot (I pay the $7/month for TEP).

I figure if you flash too many times eventually your flash can become corrupted. I've been running on rooted stock since I got my new evo several weeks ago and I haven't had a single unplanned reboot since.
