Dear community,
i have a reboot problem with my gnex gsm for several weeks now. The phone seems to be rebooting randomly after freezing. The only situation where no reboot occurs is when it is attached to the pc via usb docking station in developer mode.
Ususally, i had cyanogenmod nightlies installed, but i also tried stock 4.2.2 and 4.3 images. Moreover i tried several full wipes using cwm and twp recovery. After the last wipe, I did not recover anything using titanium backup. At the moment i am running on 4.3 stock image and stock recovery with no root. Bootloader is still unlocked. The phone keeps rebooting...
Has anybody an idea where to locate the problem (probably some certain log files) ?
My GNex had that problem. It started with random reboots. Then got into a boot loop from which it never recovered.
Good luck. Hope you don't have the same fate that I had.
Try flashing back to stock and lock and unlock bootloader. If that doesn't stop the reboots, IMO, time to look for a new phone.
Edit : You might want to send it to Samsung for repair, if you are still under warranty.

I've already tried your suggestion, but it didn't help.
Actually, I'm still under warranty, but i was hoping to solve the problem by myself to avoid being without phone for a few weeks.

Already tried that, i have a replacement battery. By the way, the reboot problem also occurs when charging from the normal power supply. Only the usb connection with debug mode avoids rebooting.
Thank you for your advice.

Okay, so what do you think you can do next? That replacement battery, is it a stock battery?

Yes, it is not distiguishable from the original one.
I was hoping, that there can be any hint in some sort of log file or something.
Have you tried booting into safe mode to see if it is an app issue?

Just tried that, also no difference
Are you using the original cable to charge it? I've had problems where using cheap ebay cables made the touchscreen all jumpy and needed a reboot to fix. I changed to the original cable and it never happened again. Dont know if you could have a similar problem but with random reboot.

I'm using both the original cable and two docking stations from amazon, one with ac/dc adaptor and one with usb. The phone always reboots no matter if it is charging or not. Only when connected to usb in debug mode, there is no reboot.

I strongly suspect a hardware issue. You might be better off sending it for warranty repair.

SAME PROBLEM!
Tried with several ROMs and Kernels, also stock, disabling proximity sensor (there is someone with this sensor issue...) but nothing changed.
Now I made a fuuuul hard deep wipe, and installed AOKP ROM with Nexus Toolkit. I have to check if it will be working, if not I'm going to restore phone to stock (locked unrooted etc) and then try...
Same problem here.
This happened also to me on August... was an hardware issue for me

Still not working... I wiped everything and restored phone to stock locked, and got, in one day, "only" one reboot and two super-lag (it's better than before but it's not good). I gonna send it back to assistance...

I had the same problems... i've tried to make a clean installation of the stock factory image ... sent to assistance.. it was an hardware issue...
Have You tried to use the flash-all.bat to restore the factory image, the executable inside the factory image archive that flash the stock image automatically... try it

I reflashed with the Nexus Root Toolkit the factory image, so I guess it made automatically the flash-all.bat.
Tomorrow I'm sending the phone to assistance

So What was the hardware issue because i have the same problem and out of warranty..... And I would like to repair the phone.
If the costs aren't to high.
It is happening to my gnex since yesterday.
I was on shiny Rom and all of a sudden it began rebooting randomly.
Looking at the last_kmsg I found a kernel panic related to I/o error of the ext4-fs (or something similar).
I performed several wipe, thinking of a kernel issue.
It continued rebooting randomly so I completely reset to stock 4.3 including format of sdcard.
I have the feeling that reboots began when the sdcard began to fill.
I also re_locked the bootloader, but reboots still occur.
It is probably a faulty Emmc chip, I will go to the store for warranty.

Hey guys I have a weird problem. When i turn on the phone, it reboots itself after several second. When i take a photo or make a backup with titanium backup at that time, all data goes away after a reboot. I tried doing a factory reset and i tried to format all the data partition and it is no good. I am really frustrated because i cannot use my phone for more than a week and i cannot afford a new phone right now. Hope you guys can help me.
Cheers

First try to flash stock via fastboot. If that fails try to lock your bootloader with fastboot with this command: fastboot oem lock. If it has no effect your emmc is fried..

I waited a little bit longer and everything went well. I rebooted and the phone booted into my old custom rom with all my apps installed. I even got the same sms from 10days ago again like it is the first time. I played with it a little bit and it made a popping sound with instant bright screen and rebooted itself again. I think this is definitely a hardware issue what are your opinions?

Use the flash-all.bat.. If that doesn't work execute this command: fastboot oem lock. If your bootloader isn't locked your emmc is fried.

I tried flash-all.bat and it didn't worked. Then I tried to lock the bootloader. It was a success, I even tried to unlock it and it said are you sure bla bla bla. I clicked no and rebooted and it booted to my same old friggin ROM!! I rebooted into the fastboot and it says unlocked again. I think that my phones emmc chip locked itself in a particular state and it doesnt allow any changes to be made on it. What should I do next? Is emmc repairable or should i start to searching for a new phone?

I have the exact same issue.
The phone shut itself down at some random point - if it is being charged or on a laptop it seems to be a bit more stable.
When it reboots, it goes into the status from the day it first happened. It asks to update apps again and even though they are updated, the next time the phone starts, it happens all over. If I delete an app, it will be there again after reboot/relaunch.
All the settings remain the same.
My phone is currently unlocked but not rooted and runs stock 4.3. I tried to flash stock 4.3 again and even 4.2 - later I tried Cyanogen. I use CWM to format /data, /system, /sdcard, deleted cache and devlink cache multiple times.
Each time it boot, it remains the same background, settings, and so on....
Bumping it up - really hope that someone has an idea what I could try to fix this...

I gave it to warranty and they said the eMMC chip is broken. They are going to fix it soon. But I already got myself an LG g2 so it does not matter anymore lol. Try the warranty and good luck.

It's dollar equivalent is about 50$. Normally they didn't accept my phone to warranty but I know a guy, who knows a guy who knows another guy that works in Samsung Turkey so I got that worked out:laugh:
Hey, i flashed CM11 about half a year ago. The last Saturday (20/12), it started to go in an infinite loop. First it could boot in apps, but then it crashes all the time. So What I 've tried:
Reset factory data/davlik/cache
Flashing another rom via Recovery
Bring back to stock via bootloader (cmd+fastboot)
Downloading mode (ODIN)
OmapFlash
Nothing made even a little change to my phone. It boots in the same OS, and it crashes all the time. It's like its in a readonly mode. It's like it has the program for PC Deep Freeze, that restores your phone to its first condition in every simple reboot. Can you help me plz?

Forget about #1 and #2 in your list.
In #3, what happens when you try to flash the images?

Nothing, still the same CyanogenMod OS. Even if I run oem lock, after rebooting to bootloader it will shown as unlocked again.

If the images appear to flash properly in fastboot, but you are still on the same ROM, then I would suspect your NAND is toast.

What is NAND. Is NAND phone's internal memory? And what can I do now? Is it a solution or is it a hardware issue? Thank you for your help btw

Yes, it's your devices internal flash memory. It looks like there is something wrong with it. (Others have had similar issues in the past.) So, yes, it looks like it's a hardware issue and there's nothing you can do yourself to fix it.

Hello!
I got a Galaxy Note 2 second hand and there is something wanky going around.
So the current status of the phone:
The phone will not go into twrp or odin mode without the charger in. However, I check the battery voltage and it was at full charge, 3.4v? ish?
When just pressed power button alone, it goes into a bootloop. So far, it glitches into the galaxy note 2 logo then back to battery with screen. Or other times, it goes into bootloop with only battery screen then on and black screen, which this further repeats.
There are no partitions mounted when observed inside twrp. 0mb so I am assuming that the previous owner tried to flash a custom rom and may have failed at or something.
So my current conclusion of the phone after researching and experimenting with a little knowledge about anything:
The phone has its partition table messed up (ugghghghgh) and there is no platform for the OS or Android to be flashed on to when I was trying to using odin for couple past days.
Any ideas? Anyone have a PIT file that I can test this with? I got some pit file online that I assume that is for Sprint Galaxy Note 2, but re-partitioning with that PIT doesn't seem to do anything.
Any ideas how to approach this?
P.S. it also says that it can't mount /data. Assuming because it doesn't have any partition within the phone itself but could there be any different reason?

Ok, update. When I do wipe/factory reset, Galaxy Note 2 turns off in the process. I'm now speculating that it is the battery at fault so I ordered a replacement for it. I hope this solves the problem and I will update when I get the battery.

AYYYYYYY!!! I just hotwired a spare Galaxy S4 batter to my Galaxy Note 2 and it works! It boots up into factory mode, , but I think I will figure out how to fix that on my own! Thank you for the PIT file you have provided me! Thanks a bunch! I concluded that it was the battery that didn't hold the charge thus the phone wasn't able to cycle into the boot sequence!

Hi would you be a le to provide the pit file ? Im in the same boat with my note 2.

i too would like to request this pit file please...
So a week back.
I was just chilling on my phone playing clash royale
And all of a sudden..
My phone just rebooted..i thought it is normal...as i am rooted of due to some issue it rebooted
But after waiting for some time... I saw that... It is rebooting again and again to the galaxy note 2 logo and was not going ahead
So i plugged in my charger and it went to the homescreen...but i was unable to do anything
Yesterday after googling everything my mind coud thing
But got no result for this issue
So i decided to flash stock rom
But even after flashing stock...it is behaving like before
I even did a full wipe including internal sd from twrp
Still nothing.. Then i decided to restore it from a previous twrp backup created a year before.. Still the same thing
Not it is successfully booting but..i still cant go past lock screen.... As soon as i unlock...it just freezes and reboots..
And as soon as i remove my charging plus...it starts to reboot again like crazy... Plz hepl... Never encounterd this issue before
I love my note 2 and dont feel like changing my beloved phone
Have you tried a factory wipe using stock recovery right after flashing stock rom with Odin?
If nothing works, the memory chip may be damaged.

If the memory chip is damaged in that case

You would need to replace the motherboard if the memory chip is damaged.

I dont think...that it is the sds (sudden death syndrome) my phone only turns on....while im charging it. But if i enter recovery while charging the phone...and then....if i remove the cable... It stays normal
But as soon as i quit the recovery mode and turn on my device....ut just does not show any thing...
I can enter download mode as well
But recently... It started guving me error like....cache not found...something like that....
I will post a pic...as soon as i reach home
Failing to mount partitions is an indication that something is wrong with the memory. If flashing a stock ROM with a pit file is successful but does not allow the data and cache partitions to be wiped/mounted or the ROM cannot be booted, the memory chip could be damaged.
