Galaxy Note N7100 keeps shutting off by itself

Hi,
I have a Vietnam made Galaxy Note N7100 which is almost not usable, unit does not comes with any warranty as it is an export set. It runs on the default ROM and is not rooted. Initially the unit works well for a few hours after installing some apps and did some customisation, after I locked the phone, the phone seems to go into deep sleep. I'm not even able to shut off the phone. Worse still, taking out the battery and put in back after mins do not work. To turn the set on again, I got to take out the battery for a few hours or so, then I can start the unit again.
I initially thought it might be some software conflict, I did a factory reset and leave the phone there for a while, the issue persisted.
It is also not the battery issue as I have use the same battery on another N7100 and it works well.
Is there any advice on what can I do to remedy this issue?
Thanks

It seems like a software issue, I would install 4.1.2 jelly bean stock rom. Using Odin. As you cam see its out already Here is the link you can go to and follow the instructions. Good luck man.

This came to me as well, but the set auto shut off before I can even root the unit.

Have a fix for you guys
I had the same problem after some messed up rom flash. If my Note 2's screen goes off for more than 10 seconds, I wouldn't be able to wake it back up without reboot... It was basically in an unusable state. Luckily after 2 whole days of digging I've found the solution.
1. Go to this thread http://forum.xda-developers.com/showthread.php?t=1915386
2. Scroll about 1/3rd of the way down and look for the attachment "BOOTLOADER_N7100.zip"
3. Flash the BOOTLOADER_N7100.zip with Odin using the Bootloader field
That's it!
Good luck guys. I created an account specifically to answer this question. It was a major pain in the ass finding a fix for this problem so I wanted to make sure I spread the fix on this issue so others don't need to suffer through the same thing.

SOS please
i now have the same issue where i tried the liquid rom on my n7100...as soon as it installed my phone started switching itself off within 5 secs and show a red battery light..and no love nor money can I get it on without rebooting..
i tried the bootloader in Odin after re installing the stock rom..but as soon as i select start..it fails??
Anything else?

I am also experiencing shutdowns with my Vietnam unit. I have 4.1.2 original ROM and I tried many possibilities to solve it. No success. The phone shuts off if I start an online radio (or tunein radio) and after max 2 min it shuts off. Doesn't matter if is on data plan or through router.

Had a problem of the phone freezing and had to restart the phone. Then again it would freeze after some time. Flashed stock rom with bootloader and pit but it still persisted. Sent it to the service centre and got my phone back yesterday after mb change. The new mb is with the newer firmware.

This is a real problem with the Galaxy Note 2. I built a quick site to showcase the problem and to post a video that shows exactly what is happening. I am unable to post external links, so just copy and paste the following domain in to a new browser, making sure to remove and replace the DOTs: wwwDOTgalaxynote2shutsoffDOTcom

note 2 switching off by its self
Had same problem, I switched of data, wi-fi bleutooth, gps, switched them on again 1 at a time.
Phone worked ok untill bluetooth was on again, then it shut down. I think the problem is with Bt.
I emailed samsung support who suggested i connect to kies to check i had latest firmware but i
knew i had, they also suggested a factory data restset, (settings- back up and reset- factory data reset).
Did this last week phone has been working fine since.
Hope this helps.

HORRIBLE

Same problem here, BT not working and my Note hangs every time the screen shuts off. I can wake it up immediately but after 8-10 seconds I am unable to turn it on again, must hard reset or take off the battery... No solution found so far. Flashing stock fails on sboot.bin also...

[Q] Galaxy Note 2 dead.

Hi all,
I have a galaxy note 2, bought in November 2012, I rooted it a few months ago.
Yesterday it was fine, battery was fully charged and it was in my pocket.
It was not doing anything out of the ordinary but when I went to check the time I noticed it was off and I couldn't get it to switch back on at all I tried removing the battery, putting it on charge and still nothing. I tried recovery mode too - nothing.
The only thing that happens when i try switch it on is the little red light from the proximity sensor flashes for a split second.
Has anyone heard of this before?? I've searched and cant seem to find anything like this.
Any help would be greatly appreciated.

try to flash Stock firmware via Odin....

Unfortunately this is the main symptom of Sudden Death Syndrome (SDS). There is no known way to fix it by yourself.
Contact samsung service center ASAP.
Can you answer these questions.
Which firmware was installed on your device?
Have you updated your device to the latest update?
Till you updated it, have you done a factory reset with the old firmware?

Exactly what was happening to me. Had the Notification LED blinking, wanted to check, couldn't manage to turn on the screen. Tried rebooting, but can't even see the boot-logo. Battery pulled - nothing. USB port not working when connecting to a PC.
I had MIUI on it with an increased counter, since here in Switzerland it isn't a big deal when you mod your device.
I hope they will ignore the fact of the increased binary flash counter...

I had this problem to once, after restart it works again and others also had this problem. Someone fixed it by disassembling the device and was about LCD ribbon that cause this behaviour. Bad quality control as it seems to be and shame on Samsung.
Send it back and replace it if possible, or for repairs and if want to fix it you self:

I had this problem but after rooting my device, so I did re-flashing with stock rom and everything went normal.
I think it is a software not a hardware error. I had this problem with nearly all Samsung tablets (p-1000, p6200, 7500 and lately with the note 10.1_2014)
and every time I did re-flashing with stock rom and everything went normal.

I guess your wifi is not working as you like.
If thats the case, You need to revert back to stock rom.
This time while using ODIN uncheck auto reboot. Let ODIN complete the process.
After PASS. Go to stock recovery and wipe /factory reset.
After that boot your phone. Your wifi should be ok.

I have had the same problem. I had to squeeze the phone a little towards the antenna side of the phone and guess what wifi started working.
Earlier I thought that it was a kitkat issue and searched high and low for every possible solution. I too removed battery for good 10 minutes to get wifi back.
I don't know exactly why that works, but my best guess is that the contact point between antenna and board are somehow loose. When you squeeze it sits in the place.
Just try and see if anything good comes out of it.
Press thumps up if you found this suggestion helpful.

Told you already. Antenna side. Btw if u disassembled the phone, did check for loose connection between antenna and motherboard. Check utube videos to locate specific parts.

Note 2 keeps restarting everytime!

Hi guys. A relative asked me if i can repair his note 2. I think his network was locked and the phone keeps restarting everytime. I flashed a new firmware on the phone. The one I use on mine..XXUFNG1, and also I went into recovery and clear data and cache after flashing. But still the phone keeps rebooting everytime. Why is that and how can I fix this?
Note : It's not bootloop or anything. You can switch on the phone, use it for like 5mins and then it freezes and restarts itself. And it goes on like that. Sometimes it doesn't restart also and you can use for more. But most of the time after 5mins, it restarts.

Everything stock..like I said! Before flashing to the newest rom too, everything was stock.

Was the phone dropped or exposed to moisture? Possible battery problem? Reboots even when connected to a charger?

Hi..thanks for reply. I tried another battery in it. The one I use myself. But it still restarts. I don't know if the phone was dropped or anything though. The relative just told me that it needs to be unlocked. Do you think it's software related? Or something is damaged in the phone?

Since it is running a stock ROM and still behaves this way after a factory reset, I think there is a hardware problem.

I might have a similar problem. I copy from another thread:
Hey guys,
I like this rom so far. But since 2 weeks I got an issue.
My phone randomly turns off, atleast I guess that's what happens. Sometimes the "notify" LED is on permanently but the display won't go on. To start the phone again I have to put out the battery and put it back in.
My battery is randomly empty pretty fast even if I just let the phone turned off. This happens like every 5 minutes.
I already bought a new battery but the problem hasn't changed.
What to do now? :>

I like the phone. It's over 5 years old and runs like the first day. Except it DOESN'T wake up anymore after a short time when the screen is off. I can press the power/home button as many times as I want and wait for 5 minutes, screen will still be off. Only way to "wake" it up again is to put the battery out and in again.
Currently I don't have enough money to buy a new phone and I can get a new motherboard for 25$. But I'm not sure if this will fix my problem.
I'm not even sure if this is the ROMs problem since it worked with all earlier versions of this rom perfectly and even the latest release worked for weeks/months.
Click to expand...
Click to collapse
As long as I leave the screen turned on the display/phone won't go off and I can use it as always. Even the battery don't drop drastically then.
It might be exposed to moisture tho. When I take a hot shower I'll leave it on the window sill and the room gets steamy.
ROM: [7.1.2 r24] LineageOS for N7100 [Unofficial] - Version from 08.10.2017
GAPPS: Open Gapps ARM 7.1 Aroma - 03.05.2017
Baseband: N7100XXUFND3
Ril and other stuff I don't know where to check.
Some years ago I had the SDS and the motherboard was changed without the EMMC bug.
Sometimes my phone only charges in slow mode too.
I try a clean install and newer pico gapps now. Maybe it will solve the problem. I'll reply then if it worked or not.
[EDIT]
Since my phone was low on battery I turned it off completly and put it on the charger. After an hour or so I wanted to look after it.
The green charging light stays on and if I want to turn the phone on nothing happens. The light stays on even after removing the charger.
Seems like a hardware, not a rom problem? Will changing the motherboard fix this?
[EDIT 2]
Quick update. I fully wiped/factory resetted and clean installed newest version of this ROM + newest mini pico GApps. Still the same problem. Gonna try it with another ROM/kernel now and if the problem persists it's a hardware fault.
[EDIT 3]
Fully wiped again and changed ROM+Kernel. Still the same problem.
