Consistent Rebooting - Text Related?

Guys,
I'm pulling my hair out over this. My MDA Vario has often rebooted itself and i've always put it down to a glitch of one form or another, but today it has been rebooting every few minutes.
Each time it reboots a text message i've read reappears as NEW, as though the phone doesn't register me reading it before it crashes and reboots. If I delete this and other messages, within minutes once it's crashed and rebooted they will all return like a CACHED memory or something.
I don't know what to do.
It seems as soon as my screen dims on power save, it won't come back on and within a few seconds the screen goes white as it is rebooting.
Sometimes reading this message or doing anything in the message application causes the crash, sometimes it's happenign even without me doing anything.
HOWEVER - once i've turned off the power saver dimming the screen, no reboot is occuring. I've gone into the messages, read and deleted this message among others, and no reboot. If I manually turn the screen off though, within a few seconds it reboots.
What is going on ?!

i have the same exact problem! I changed the battery the day before yesterday and it has not done it since, but im not sure if it solved the problem as sometimes it does not restart in one whole day!

N1 Turns off by itself

Hi everyone
Annoying issue. My phone is turning off (power off) randomly. Sometimes I take it out of my pocket and it is off. Then I have to reboot again with power button.
Anyone else has the same problem?
I am using CM 5.0.5.3.
Thanks

Mine reboots regularly but my phone is stock

Mine is running stock & has never ever turned off . You might have a faulty phone or problem with the rom you are using.

I had the random reboot problem on stock too, but it never stayed off.
Still happens on CM, but much less often.
Can you reproduce the problem? If so keep "adb logcat" running and see what the error is.

try pulling the last_kmsg from the phone..... Some information in there. Will at least let you know if it is hardware or software crash......

thank you martin
Little help. How do you pull that particular file?
thanks a lot

its a file, probably named so becasue it contains kernel messages (errors, debug).
Located at /proc/last_kmsg
you could pull it, tail it etc
example: tail -f /proc/last_kmsg

Yup, have the same problem sometimes
Both on stock and CM
Now I am running Modacos desire rom, and so far I don't think I have hade any unexpected reboots or shut downs

I have a similar problem but mine will sometimes turn off and not go back on for about 5 mins or so, sometimes longer, pulling the battery or even plugging it into the charger doesn't even give me the orange LED. it goes completely dead. it also sometimes gets stuck into boot mode like loop. this is on a stock N1 but this happens maybe 2-3 times per month. HTC said I can send it back or have it repaired but it's too much of a hassle and at least mine doesn't have dust under the screen if the problem persist I'll prolly send it in. BTW it's not a battery issue because I have two batteries and it's happened with both. faulty phone for sure.

I've had this happen once or twice the first couple weeks I had the phone.

It started happening to me when I installed appbrain and appaware so I uninstalled both and not done it since, so for me I think it was one of those apps!

Mine has done it once, I'm guessing it was an app that did it since one time in nearly 3 months isn't that big of a deal

I am still investigating. Its wierd that it happens morewhen I put it in the pocket. Its fine when its on the table

I have the same problem. Noticed it only happens when radio signal is very weak and a phone call comes in...Don't know if that makes any sense :S

Note 4 Randomly Turned Off Won't Turn On Anymore

Hi everyone, after trying everything I could to fix this phone I don't know what to do anymore so I'm here asking for other options.
So the story is, I was just using my phone as I usually would that day and it just randomly turned off and won't turn back on anymore.
(it randomly turned off before a couple of times but it would always turn back on)
- It won't go into recovery mode or any other of the 'modes' (I tried all the different combinations of pressing the keys).
- It's not a battery issue as I've tried my battery on my brother's phone (he has a Note 4 too) and it worked fine and I tried his battery on mine and it wouldn't work.
- I tried the 'drain' method (removing the battery and holding the power button for a minute or more).
- I tried using multiple cables to charge my phone nothing worked.
I didn't drop my phone, wet it, root it or anything and it was working fine the day it happened until it just powered off by itself. When I plug it in my laptop it would make
a sound indicating I've plugged something in but nothing happens. It was version 5.1.1 model SM-N910F.
TLDR; Is there a way to somehow recover the files in the internal phone memory?

This is happening to me as well, also started in February. I'm suspecting a hardware issue. Tried it ALL but rooting. In the past 30 minutes my phone has booted and rebooted itself till it died. If someone can confirm it is a hardware issue. Maybe it's time to unite and get it fixed for free. ~Tamarnouche

Recovering data from a brain dead phone may not be possible, as it probably need some internal component replacement which may erase the data(Mostly). Have u tried connecting it to pc? Better give it to service immediately. Good Luck.

My phone has done exactly the same thing, happened in February too, initially it did the random freeze then started to reboot itself, went back to stock software and full wipe but no improvement; now it will only boot if I leave the battery out for a prolonged period, otherwise it doesn't respond to the power button at all.
I occasionally see MMC Read Fail on boot but not all the time so presumably the internal memory has a bad contact or is failing.
Can it be replaced?

I have the same problem with my Note 3. Only if I keep the battery out for a long (over 24 hours) time I can see the boot logo. So if you find a solution to this kindly don't forget to tag me, will really appreciate it.

I was wondering..
I came across this Forum group since I was looking for boot problems with my SM-N910T3
I hope flashing pit will resolve this..
I recently started to have some low level issue and was hoping it was partition/boot related and not hardware.
Randomly phone boot directly into Download mode with error;
ddi: mmc_read failed
Often I have to pull battery and hold down /power / home for 10 sec to boot up again.
Thanks

Phone is Broken

Alright, so like many people, I tried to play Pokemon GO. I was playing for about 20 minutes on my break at work, and I noticed that as I was switching between it and other apps, my phone was getting pretty laggy and bogged down, to a point where the phone just froze for a minute, then when the screen turned off. I couldn't turn it on for a further minute or so. Eventually after a few minutes of this, the phone just crashed, Upon trying to restart it, it went to the odin screen, saying "mmc_read error", or something like that. I pulled out the battery and let it sit for a few minutes and tried again. It started to boot, but it was stuck on the phone's model splash screen for several minutes, which its never done before. After the phone finally got booted up, it would freeze often, and I would not be able to turn the screen back on for several minutes at a time. This has persisted all night, crashing and freezing for the remainder of my shift. After I got home I tried restarting it again, and the phone wouldn't turn on at all, so I again pulled the battery and let it sit for a while. I've done this a few times now.
Sorry it's a bit lengthy, but I tried to recreate the events of what's happened as best I could. If you need any other info just ask
I have uninstalled the game from my phone now, the phone is completely stock, no roms, not rooted. I do not recall it feeling too hot as if it had overheated
I really am not experienced with issues like this, and I really would not like to have to buy a new phone

Hmm, that error is supposedly of the EMMC failing, now you will be lucky if it was a one time incident. Now to be quite honest I don't think anyone could tell you that whether the problem will come back or not, and you can't do much anyway. I will say if the phone is running okay now, let it. Or if you are really unlucky then the problem will come back, the EMMC might fail permanently. But if you see one or two more reboot incidents like that, I think its fair to conclude that your phone is done mate.

Currently I can turn on the phone, but after I turn the screen off, it won't come back on again

Oh darn mate. You could try to wipe the phone completely from recovery (TWRP) and then flash the stock ROM. Now please don't blame me if the phone gets dead or something after that, cause my Note 3 died just few months back, and it took me a good couple of months to get over that fact. However one thing is for sure, if your emmc is supposed to fail, or motherboard, then it will no matter what.

HTC 10 (verizon) reboots randomly.

This may seem like a noob thread (which it probs is) but my issue is probably rare in htc 10 phones. You see.. my htc 10 just randomly decides to reboot from time to time. I've noticed some pattern to it but it still does not help. The reboots occur randomly. Some days, no reboot at all. Other days, it reboots so many times. Reboots more noticeably while watching videos (I got the phone knowing this problem). So, a logical person might say, "Hey, why don't you reset to factory settings/why don't you flash stock ruu/use htc repair tool or sync manager." To which, I reply, "I have done literally everything I can except getting it s-off and flashing custom rom on it. And the best part? when I select repair on htc sync manager, it says, "No software available for your device""
It may be a hardware issue. Most people say that it could be related to battery. If it were related to battery, the phone would just completely shut down and restart. However, in my case, the phone hangs or freezes for about 10 seconds and is unresponsive till it finally shuts down and reboots. I've put in safe mode as well but still no luck.
I've completely gone into zen mode now. I don't watch videos anymore xD
Help would be GREATLY appreciated. Thanks.
