Evo 4G randomly resets itself

Hey all,
I've been using my HTC EVO 4G for quite some time now (nearly a year), and just recently it started acting up. As the title implies, my phone randomly shuts itself off and starts itself back up-- for reasons I cannot determine. Usually when it does it once, I find that it goes on a rampage and shuts itself off before the phone even starts up. It will continue to reset itself for 3 or 4 times before it starts working properly.
I've honestly no idea what could be wrong with it. When this first started happening, I was running Fresh ROM 4.2 (but I've already been running it for a while-- it couldn't have been the ROM), and the default kernel for Fresh. I decided to boot into recovery for an earlier version of the ROM, but to no avail.
Finally, I decided to get a whole new ROM (am currently running on Synergy) and kernel altogether (currently running on netarchy kernel), but again to no avail.
Of course, I did a complete data wipe upon installing Synergy, so it can't have anything to do with phone's software, can it? I'm assuming it must be something physical; and am seriously considering purchasing a whole new SD card. (About the SD card: whenever I try mounting my EVO as a disk drive, immediately after I select the 'Mount' option, a notification saying 'Preparing SD card' pops up, and fails to ever mount it. This, I believe, is due to the fact that I'm not on a .92 Hboot, but it is nevertheless worth noting.)
Has anyone else ever had this problem? Any help would be greatly appreciated.

Edit: The fact that I can't mount my phone as a disk drive is actually a problem in itself... I need to convert to Hboot .92, but my file system isn't FAT32 (at least, I'm assuming so, since it doesn't load my PB31I.zip IMG in Hboot) and I can't convert it if it doesn't connect to my computer... Guess I'll go back to Fresh.

Does your phone kind of heat up sometimes? Like in the front of the screen? My did and it turned out to be a physical problem. Bad charger port, sounds weird but thats what I was told. You might need to buy another one.

Yeah, I had originally thought it was an over-heating problem as well. It used to happen most of the time while I was driving-- with the sun hitting the phone directly. However, it's been doing it in-doors with A/C and virtually every other place . I just took notice of it in the car because that's when music was playing.
Ultimately, I might just consider transitioning to the Galaxy SII.
Thanks for reply. <3

I've been having same problem had my evo since day 1 and never any problems up unitl a few months ago.but now i definetly know i need a replacement mine phone gets super hot as well originally thought it was the rom but went back to stock all for nothing because the problem still remained

Is call power cycle the only way to fix it is to get a refurbish phone from sprint they know about it, they will do a test on it and order you another phone with the new 2.3.3 that cant be rooted, is not the sd card it is something on the hardware motherboard

Strange restarting at boot up

So recently im getting a strange restarting of my phone right after a restart or a boot up.
It doesn't fully shut off and start up..it seems to be like a soft reboot and it just starts up the entire home screen again.
I've noticed 2 weird things on when its happening...usually when the automatic time and date update...or when USB media scan is running or is about to be complete.
I've fixed permissions ..kept my clock speed at stock.
I'm running BeastMod 4.2 with the latest Synergy kernel ...and Go Launcher Ex.
I've flashed other kernels too and it's happened with all.
Eventually ..after a few battery pulls and a bunch of full blown restarts...it stabilizes and runs like it should.
Ideas?

I was having this problem with my first SGS2 and I tried every rom out at the time and nothing worked so I just exchanged it and I haven't had any problems with the new one I got.
Mine started doing since day one.
Did yours just start or did it have that problem from the get go.

It happened pretty much after my first kernel flash...and was on stock rom too. That's when I pulled the trigger to go with a custom rom hoping it would fix it.
Dang it...I don't want to have to deal trying to get it back to stock.

Do you mind sending me the same message too? I'm having this problem with a few different mods. I had it with Domination 2.0 and with Juggernaut 4.1. It happened really badly when I was at the airport. After I changed my phone from airplane mode to non-airplane mode, and when I started trying to do stuff soon after it started, it would go into an endless reboot loop. It wouldn't restart fully, but the screen would go off for a few seconds, then I would see my lockscreen again. It would go through this process about 4-7 times before finally stabilizing.
I really don't want to get a new phone because I just paid to have an invisible shield installed around the full body less than a week ago. Thanks!

Did you have this problem being stock or just after flashing roms?

Interesting enough.. I did a test.. I restarted WITHOUT my external SD card... and guess what... of booted up fine. Looks like I have something going on with my external card.. but it works just fine... so a conflict somewhere. I went through the card last night and deleted some stuff... but after I put the card back in... boom...started to happen again.
I'm either going to try to copy things over and format the card.. or just get a new card.
Try it out and let me know what you guys get too.

Getting a new card wont do much if the data on the card is what's causing your phone to go haywire.
Do you have apps stored on your SD card?
Sent from my Hercules using XDA App

I'm sure I have some on there... app...but I've checked any folders that seem "off"...and delted a lot of those... so mainly what's left are pics and music... haven't had a chance to format the card to see if that works... and I could be totally off base with this too. Just trying different things before the last resort of getting a replacement phone.

I have been having this exact same problem for a while now. I have tried it on three phones that I've had (original, replacement, and another new one). No matter what rom/kernel i've tried, same thing all the time. I have wiped many a times, fresh installs, formatted memory card, tried without memory card, and same thing. I have never had this problem with HTC phones and really have no idea what to do anymore. Just how weird that everything works well on stock.

Well... mine for sure is my SD card gone wonky... I've done 5 seperate no SD inserted tests... and then insert SD after its already booted up and working fine.
Once I inserted the SD... it would go through the scan and crash.
After a bunch or retries... battery pulls etc.. it finally settles down and works fine.
For yours that its not the SD... call T-Mobile... they were ready to replace mine.

If the memory card was corrupt, wouldn't the phone have issues even on a stock non-rooted phone? I'm asking cuz my phone works great on stock non-rooted, but once I root and upload a custom rom, everything goes haywire. Im trying to find out what the problem may be.
Sent from my iCrap killer

Actually this problem for me started even when I was on a stock ROM...I'm not sure how long after rooting... I wonder if rooting had something to do with it? This issue is one of the reasons why I went ahead on to a custom ROM thinking it would fix it... it was fine for a while.. then started up again.
I'm not sure. I haven't bought a new external SD yet to test my own theory.. haha

Can someone help me pinpoint why my phone is constantly rebooting?

I have had my epic for about a month now and I love it but sometimes it will reboot like 5 times a day and sometimes it will not even go back on unless I pull the battery for a couple seconds. It is rooted and I am not going to lie it NEVER did this before I rooted it. I have tried plenty of different roms and after a while they all reboot. Most run fine for the first couple days. I will say that it never reboots when I am using it its funny but it seems to only do it when it is in my pocket. I always know when it rebooted because my headset gives the disconnected beep then I look at my phone and sure enough I see the boot screen. This is becoming very annoying any help would be greatly appreciated.

What rom/kernel/radio are you using?

I am using the Phantom Hacker blazer rom v 3.4 with the stock rouge el26 kernal. Not sure about the radio because I never touched that. I am also running the venum minimal black theme.

Its funny because sometimes it will go days and run great then one day boom 5 restarts before the afternoon hits.

Restore to stock and see if you still have the problem, if you do, take it into sprint.

My phone hasn't rebooted but I have experienced the sleep of death a couple of times in the past week. I don't understand what's causing it either but meh, it's not been to often.

Are you guys running any of Calks scripts also have you flashed the 3g/4g hotspot hack

Im using the hack that was built into the rom and none of calks scripts. I should also note that sometimes whsn it reboots it drains a good 50% of the battery.

Could a bad sd card be causing this? I ask because one time when i went to use my phone the sd card was not detected and i had to reboot to get it back. Thats probably a problem with the phone too.. I love this phone but i am getting real tired of its bull****.

When I first got the phone I didnt root it for about a week and there wasnt a reboot in sight. As soon as I rooted it, this crap started. Is this just something people with rooted phones need to put up with?

Well my sd card just failed and upon some research I have learned that a failing sd card can cause the phone to reboot so I am going to run it for a while without it and see if the problem still persists.

I have been rooted for over a month or so and have not had a single reboot. So no, that is not normal.
I am guessing something is wrong with your root or your rom install.

I believe it was rebooting because of a bad sd card. I took it out and have not had one reboot since. Also the sd card was messing up all day. I tried to acess it and it says sd card damaged. Do you know if a bad sd card can cause reboots? From my research allot of people say it can.

Yea, if its giving your errors, and the phone is rebooting, and removing it from the phone corrects the rebooting issue, that seems logical that the SD card was causing the problem.
Reformat the card and see if that resolves the issue.

Well I took the sd card out and no reboots in almost 24 hours!! I hope there is nothing wrong with this phone because man do I love it. Just a question though, could the fact that it was rebooting with the card in there be caused by the fact that I took that card out of my old Evo 4g and just put it straight into this phone without formatting it or anything? Or you think it's just a bad card all together?

I took my sdcard from my old epic,no reboots, im rooted only, no clockwork yet, I have had the phone about two weeks, I would be very upset if it started rebooting, that's one of the reason I upgrade I was flash happy with my old epic, new rom runs great for a couple days than here comes the problem

of course you should put a "clean" sd card in your phone, when you change models...there are all sorts of useless files from your evo on their, and no doubt that would cause weird behavior in your current phone..

Ya i had that problem with the evo too. All you need to do is clear delvic cache and cache partition and it would run fine again for like 3-4 days then you would need to do it again.

Ya I see what ya mean. I am going to run the phone for a couple days just to make sure it isn't a problem with the phone and if all is good I will format the card and put it back in the phone and see what happens. You all have been very helpful though as always, I appreciate it!

I wouldn't go that far. I had the same BS when I first rooted. I've been using Strongsteve's blue ROM and haven't experienced ANY problems since ie. Ghost rebooting, Los, nothing. Its made me love the phone again....trust me I was ready to throw the thing in the garbage.

[Q] Replaced SD/vibrator hardware, now won't stop vibrating!

Hi,
I had a previous issue with SD card not being recognized, see this thread: http://forum.xda-developers.com/showthread.php?t=2363052
So, now, I bought the part and just installed it. The sd card seems to be recognized some of the time, but whenever there is ANY power source, from either usb or battery, the vibrator runs non stop. I just tried wiping and flashing ROM again, from the SD card, but it didn't fix the vibrating.
Has anyone seen this issue before? I saw in another thread there is an option in a recent CM rom, so I'm DLing and going to try installing that.
I'm considering if nothing else as an option, either sending it back to ask for a different part, in case the part is shorted and defective, or just breaking the vibrator hardware so it won't vibrate.
Any help is appreciated!
Thank you

Pretty sure its a bad tray, ask for a replacement

[Q] S II t989 won't quite load but not quite a boot loop

I need help figuring out exactly what's wrong with my phone as it has very weird symptoms that seem one-of-a-kind to any problems I've been able to find already posted. Basically everytime I turn on my phone it gets stuck on the load screen with the bar near completion but it won't actually boot and it doesn't loop - to make matters more peculiar once I pop out the battery and try again then the Android guy blasts off and my phone turns on. It always takes me a second try for it to boot but it does so without fail - usually. The rare incidences that I can't get my phone to boot then I can easily get into twrp & after wiping both caches/factory reset it will boot immediately after on the 'first try'. Even worse is that my battery power has been extremely reduced to maybe 4-5hrs regardless of how much I use my phone and it will turn off unexpectedly no matter how much power is left.
the only thing I can think of is that it started soon after I put an external sd card in and tbh I don't quite understand how to take advantage of my extra 16gb yet and the fact that I'm bound to wipe my phone again has kept me from exploring my options
please if anyone can help me save my phone and maybe even link to a thread explaining how to use an external sd card properly. I got confused awhile back trying to understand partitioning and Idk which apps have to stay internal or how to retrieve ones on my sd.
Oh, one last thing, I started using a wall charger for my Samsung batteries and now I can't charge my phone thru the usb anymore without it 'disconnecting' immediately
I was using Paranoid Android before my troubles started but I'm back on stock 4.1.2. I've never posted on xda before so hopefully I did so properly and provided enough background information. thank you in advance to any genius out there who can get me my phone back!!!
