Random freezes/ shutdowns?

So I picked this phone up yesterday. Everything seems great, after about an hr I rooted the phone and installed cwr.
Suddenly after about another hr I got a random freeze and then it shut down, at the time I was browsing the web. Boot it back up and within 4 hrs I got 3 more freezes /shutdowns.
At this point I went ahead and installed EB1.1 this morning hoping this would solve the problem.
Well it didn't, I've had 5 shutdowns in about a 10 hr span.
Is anyone else experiencing this?
Unfortunately I wasn't stock long enough to see if it was caused by root and/or cwr.
Anyone have any idea what could be causing this?
The freezes /shutdowns have happened doing different things and even while not even being used.
[Problem] So it freezes and shutsdown right after and I have to do a battery pull because it won't let me reboot without it.
It happens randomly and quite often.
It's not a rom problem because it was happening before I flashed it.
Really happy with this phone and I really don't want to go exchange. Asking this forum before I call T-Mobile because most likely they will have me do a factory reset, for them that solves everything!
Thanks.

I fixed permissions when I flashed the rom.
What difference would it make to do it again?
What do you think the problem is that this would help?
Either way I'm gonna fix permission and see how it goes.
Thanks!
Hercules, Hercules!!

I have had my phone for over a week and started having issues about 2 days later after root. My battery would not update and i was running updates from the market and the phone froze and shut down.
Rebooted and charged over night. I woke up around 4am and my phone was very hot. I got up this morning and flashed EB1.1 and so far no issues. It was odd and i cant quite find the root cause as to why it froze. no real issues before i rooted and no issues after i flashed EB.

Wont hurt. Try wipe cache and data too
Sent from my SGH-T989 using XDA App

Well wiped cache and dalvik, also fixed permissions.
No go, same problem.
I'm gonna wait to flash any new rom the comes out to see if it fixes anything. If not I'll just have to return.
I know with my G2X I was having random reboots and flashing certain roms would fix it so hoping for the same here.
Hercules, Hercules!!

Not sure if this will help, but when I got the phone on release it would constantly shut down and would not turn on. I had to keep holding Power button, much longer than normal. I ended up restoring the phone to factory default settings. No more random shut downs since.

Any chance did you restore any apps on titanium backup with old system data? That can cause alot of issues.

Yeah, I know bout that one. No I didn't do that, I actually wiped my SD card as well just in case something on there was causing it and no go.
I was curious to see if root could of caused any issues, but I guess not because no one else is reporting same issue.

So were you still stock or had you rooted already?
So you're talking about a factory reset right?

I was still on stock. Yes a factory reset.
The phone would shut off while in apps or trying to surf the web. It would also randomly shut off while in my pant pocket and in my jacket pocket.

I get random reboots, stock and stock rooted, haven't flashed a rom yet. Reboots a few times a day usually, is kind of annoying, gonna flash a rom, see if that helps, otherwise I'll be hitting up tmobile too.

Sure don't have this problem

u can always odin back to stock now that we have it!! that fixes most probs!!!

I used to have reboots problem with my G2X and flashing a rom fixed it. The weird thing about it was that it was certain roms, not all of them.

Screen turning on and off by itself

My daughters att gs3 screen keeps turning on and off all the time all by itself. its all pure stock, NO root, stock rom still.
Data block on her line.
She doesnt have much installed in it and i dont want to reset it. is there anything i can install that will tell me what is causing it?
I know there is a better battery stats app. Not sure if it needs root? Imunsure it will help as its a bit confusing to read thru all the readings

Strangely mines did this for a day and it killed my battery. Hasn't happened since then though. Glad I wasn't going crazy. Mines is also stock no root or anything.

This is happening on my phone too, and when the screen turns on by itself it won't time out, have to manually lock it. Thought it was something to do with smart stay but mine is disabled. I flashed a custom rom yesterday and noticed it still happening. Carriers hardware support thinks it is a hardware issue and want me to rma my phone.

I think your only option is reseting the phone to make sure the phone doesnt have hardware issues. Try a fresh stock install from odin.

[Q] Random Reboot

Hi,
History:
I have a problem with my Nexus. It randomly reboots. Nothing seems to help.
It started after a few months after I was rooted on CyanogenMod 10.0. In 3 days, it quickly escalated to a reboot every 10 minutes on average.
A factory reset (without user apps installed on it) on CynogenMod reduced the frequency (every hour?), but didn't eliminate it.
Unrooting to stock Jellybean 4.1.2 seemed fine only in the first week. The problem came back afterwards, and updating to JB 4.2.1 didn't help.
Now, 2 months on stock ROM, I get even more random times. Sometimes it is 2 times a day, sometimes once a week.
Just before it:
I get a metallic screeching noise for 1-2 seconds, and immediately following that, device turns off with a "pang". Although these days I HAVE had situations that the sound came for up to 3 seconds (and the screen freezes), but the phone worked normally afterwards.
What happens:
It randomly reboots. The rebooting is at irregular intervals, whatever i was doing on it (even when not using it).
What happens after:
It takes much, much longer to startup again. It can get stuck at the "Google" logo screen for up to 5min. It doesn't take this long to reboot if I shut it down myself.
Any ideas? What causes this? Is it software or hardware?
Can I even send it for warranty if I cannot reproduce the problem?
I don't want to send it to warranty if I don't have to. I don't want to loose my phone for I don't know how long.

Hi, what's your eMMC version? Maybe buggy memory, try looking at other threads.

Have you tried different batteries?
GeeNex | Carbon nightlies | Rubiks

I'm new to this eMMC thing, but according to an app my eMMC Type is V3U00M. To check whether it is buggy or not it needs root, which I don't currently have. If it IS buggy, I don't have a choice but to bring it for warranty right?
No, I have not tried to changed batteries. I don't have other batteries. But can the problem really lie with the battery? Btw, my phone is less than 8 months old.

Well, I am planning to root again. I want to switch back to CyanogenMod 10.1. Lagfix app isn't needed if you can use -discard mount option right? How to use either, if let's say I'm on CyanogenMod. This is also the first time I hear of lagfix and discard mount... :/
Btw, the app i used to check my eMMC Type said that my chip is ok. No brickbug. Are you sure it's buggy?

I might be wrong here, but from what I've read at the link and other xda posts (http://forum.xda-developers.com/showthread.php?t=2029246), the V3U00M chip is not buggy (in the sense that it's stable for rooting and using the -discard command), but it does give slowdowns. I do have horrible slowdowns, so thanks for that solution I didn't know existed. However, this doesn't solve my random reboot problem at all...

No one else got any solid way to find out the source of the problem?

Same as you man...
I'm seriously considering throwing my phone to the garbage. I don't like iPhones, but google is really pushing me into it with this crappy piece of phone. Is so frustrating to have these rebooting issues, I've tried everything, from wipe to factory reset, back to stock, flash custom ROMS and KERNELS, turning location access off, uninstalling all apps/widgets that might interfere, and every single "solution" it's out there, and STILL I'M HAVING THESE DAMN REBOOTS!
Now it's even worse, I can't even transfer files to my phone anymore because, guess what... IT REBOOTS! everytime I transfer ANY KIND of file.
The only thing that seems to work for a while is reformatting and start from scratch. I've done that like 3 times already. But still after a few weeks the issue reapears... i'm really mad about this, and no one seems to care. Not Google and not even Samsung.
The only interesting thing that i found around the internet is this guy's findings
plus.google.com/113601948978986762347/posts/2ALASEC1dG2
I read the log on my phone and matches to his... but now the thing is, what do i do with this information? I'm not a programmer o something like that.
Any ideas?

I think your board is faulty. Even so, have you tried disabling SR and raising voltages across the board? Trimming eMMC? Omapflash?

He is saying that you have root you need to install trickster mod from the play store. Open the app and go to specific. Then disable the smart reflex toggles and click the oké button in the upper right corner see if that works. If it doesnt re enable smart reflex and go tot MPU voltages. Next to the words MPU voltages there is a blue plus/minus button. Click that and click the plus one time. Accept it and push again the oke button. The other two things I dont exactly know..

Honestly, if you are getting reboots on a clean stock (including stock kernel) , it's probably a hardware issue.

The thing is that after a clean stock install everything works fine for a week or two, that means no random reboots, and i can transfer any kind of file of any size with no problem. Then for some estrange reason (even with no crazy apps installed) starts with a random reboot, after that first reboot i know is time and that i wont be able to transfer files anymore, because it WILL reboot while i'm transfering files. Other thing i have noticed is that around where the camera lens is, get really hot. So I think that the reason it reboots is kernel panic caused by overheating, or the other thing is that my sdcard have some issues when writing files.
Right now i'm using CyanogenMod 10.0.0-maguro with jelly bean 4.1.2 and franco.kernel 3.0.51-nightly-512GPU and i have already tried going back to stock.
how can a I check if my hardware is fine? Is there any app out there?
Thanks!

512GPU? You mean your GPU is overclocked? Maybe try to set your GPU to stock. And if it gets really hot and you have random reboots you can try to over volt with trickster mod.

No, I don't think my GPU is overclocked, that's the full name of the kernel, you say that the kernel automatically puts my GPU to 512?. Anyways i just installed that kernel two days ago just because i thought it might make the reboots go away. I'm having rebooting problems since february (just after upgrading to 4.2.1), so i don't think that the GPU is causing the reboots.

Sending my GSII for warranty repair

So over the weekend, my phone started rebooting on its own..Thought it was a ROM bug, but every ROM I switched to (Even clean backups) would have an issue with locking the phone (Lockscreen would come back on within a second) and automatically shutting down/rebooting.... So I Odin'd back to stock and sent it to Samsung... Should I have any worries about them being able to see I was rooted at any point? I know this is such a noob question, but I just want the damn thing fixed without issues. Thoughts?

Simple answer, no they will never know, descriptive answer lol, 9x out of 10 sammy never turns the phones on, u will probably get a completely diff phone back, all they do with these is either wipe and reflash if its a software issue, or junk for parts and refurbs if its hardware related, I've never seen an issue with any Hercules warranty because of rooting

Random reboots

I am getting random reboots on my HTC m8 for Verizon, and I'm not quite sure why. The last one happened while I was browsing in Chrome, and a previous one happened when I was doing some other random task like browsing twitter. I am rooted via WeakSauce with s-on using exposed modules through soft reboots (not sure of this has anything to do with it) . Another thing, when I reboot, it sticks at the Verizon splash screen and I have to manual reboot via vol up and power button.
Also, my phone is getting pretty hot sometimes and I'm not sure why, any tips or possible explanations?

Are you using the stock kernel? Did you flash any roms or are you stock?

Well I'm inclined to think it's one of the Xposed modules causing your issue. Best way to check is with a Logcat if you can recreate the issue.

I doubt I could recreate the issue because it happens super randomly... I guess if it gets too bad, I'll just quit using my xposed and see if that fixes it

I have the same problem and so does 2 of my colleagues who are completely stock (not even unlocked/rooted). For me it usually happens while not doing anything with the phone though. It can just be sitting on my desk and suddenly reboot. It's insanely annoying and I can't seem to find any good information on the subject.

Well I also just started having some random reboot for whatever reason... Phone was also just on desk and rebooted itself for whatever reason. Funny enough though, my battery life was 96% when I last checked the phone could have drained a little bit more, but after the reboot it shows my battery as being 100% fully charged =o/

If you're stock, this isn't normal. Contact HTC about possible replacement.

Yeah it's semi-stock perhaps. I did put on TWRP again, it's rooted, unlocked bootloader(of course, else no root right?). It was fine the whole time until I installed the xposed framework and some modules, even then I've had it on for about a week and nothing happened until this morning. I took the framework off and of course also the modules, will see if it happens again in the next week or so... :fingers-crossed: that it doesn't.

For you it's almost definitely an xposed module. I was talking to the guy who was completely stock unrooted.

Hi guys,
So I was having the same problem with random reboots. I got frustrated and thought to just root and change to a GPE ROM. In the process of doing that I rooted and installed SetCPU. I discovered that the clock speed was 2265 and the minimum spped was set to 1958 by default. I felt like this was weird because that means the processor is running near full speed at all times (thus why the phone would get warm). To test I set the phone at max 2265 and min 2265. Almost immediately after reboot the phone started to get very warm. So, I changed the min to 1574 and then rebooted. It has been two weeks with:
no reboots
slightly better battery life than before
phone does not get warm
I have the T-Mobile HTC One M8. I wonder if the constant high speed was intentional. I had to exchange my phone twice before trying this. I even tried using the phone before installing third party apps and it would still reboot. I am rooted with s-on and stock recovery and now I don't feel the need to install another ROM.
Hope this helps for some of you!!

good looking out there. However I most likely won't be changing my ROM due to it working fairly nicely with my JVC KW-NSX700 car stereo. Mirrorlink seems to be functional with a quirk here or there.

Oh, I'm still running the stock sense rom

Well, this is good news. I'm going to be getting rid of my Nexus 5 for one of the... Ones... here shortly. Poor speaker and microphone quality are just two things I can't deal with anymore with the Nexus 5.
Seems like HTC tried to just have the CPU running too hot, figuratively and literally. Underclock down to like....1958 max, and it should be fine then. I know my Nexus doesn't like being run at a max of 2258 for very long, if at all. I'll get random reboots on stock vanilla android, and ParanoidAndroid.
