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] Wifi doesn't start at boot

More often than not, when I start up my G pad, the Wifi does not turn on regardless of the way it was set before. Toggling the button on quick settings, or tying to turn it on manually in settings, does nothing; it says "turning on wifi", but it hangs. Rebooting usually fixes it, but sometimes requires more than one try.
Has anyone else experienced this? I'm hoping that it's a software glitch that will get fixed in the next ota update or when I flash my next rom, whichever comes first. If it's a hardware problem, however, I'd better return it before my rma period expires. Any ideas?
Thanks!

In the advanced setting under WiFi do you have the tablet set to keep WiFi on during sleep? I never turn mine off and do not have a problem. Using a v500 not a v510.

Yes, I've experienced it, if by starting up the G Pad you mean from it bring completely shut down, rather than sleeping. Also happens when doing a restart sometimes. As you say, a further restart sorts it out. I very rarely shut the tablet down or restart it though, usually I just let it sleep, so it hasn't really bothered me, except for the first time when I thought for a horrible moment the wireless hardware had died!

Wht if you don't want to use wifi when you boot the tablet? Then you have the wifi radio wasting battery from the start. Can't you install an app tht turns on the wifi at boot?

It took 6 reboots to get wifi working this mornino! Previously it had only taken 1-2 tries. It also had seemed on previous occasions that rebooting while unplugged would be more likely to successfully turn it on, but no luck; it failed multiple times both plugged and unplugged.
Needless to say, I will never turn the damn thing off if I can help it, but I'm not exactly happy about it.
LBJM, I rarely want to start up without having wifi enabled, but I suppose you could use apps like Tasker or Llama to turn it on or off under certain conditions.

The issue isn't simply that Wi-Fi is off when the tablet first boots up, it's that it refuses to switch Wi-Fi on until it's restarted a second time, so don't think this would help.

6 is getting a bit crazy! Thankfully a single restart worked for me on the couple of occasions it happened. I've actually ended up restarting a few times over the past week for other reasons, but haven't seen this issue occur again. I'm going to shut it down completely shortly, so will see what happens then.

I would take that in for a warranty replacement. That sounds like a dodgy network chip on the main board. I just restarted today and had no problem like what you mention.

I turn it off every night and in the almost couple of months that I have had my G Pad I have never had this problem.

Yeah I would RMA your Gpad. You shouldn't have to jump through hoops to turn on wifi.

Oddly, the issue has pretty much stopped - - just as well, since I was past my RMA date! I'm going to chalk this one up to some odd app interference, since it resolved with any rom updates or re-flashing.
Thanks again to everyone for their help!

[Q] Note 3 Neo n7505 16gb Problem please help!!!

Hello,
I have a big issue with my note 3 neo. The phone randomly turns off on its own after it drops below 40 % battery. The issue seems to have started after i updated the to 4.3 jelly. When it turns off the buttons will NOT respond, the only way to "fix" it is to remove the battery and after that it starts up fine, but this happened 6-7 times in the past month. Does anyone have any idea what might be causing this ( SW, HW )?
Thank you.

Did you disable Samsung DVFS? If yes you want to try enabling it back. That resolved my phone turning off by itself when charging on AC charger.
Edit: I spoke too soon. My phones's auto shutdown when plugged to AC charger problem still there. Need to do a hard reset to see.

I'm having the same problem, the phone is completely stock, haven't dropped the phone or anything, bought the phone like 3 weeks ago. I also see a green led, not sure if it's a notification. When I saw that I thought maybe it's some power save function. But I simply just can't turn the phone on, the battery needs to be removed to start up. So I just mailed Samsung, waiting for their reply

My wife's phone has the same issue. Any update on this from anyone?

Mine also turns off when charging.

the problem is that it stays on the screen with the logo and can't access to menu. View image.

Press and hold the up volume, Home button and power button togeather until the phone gets restarted. This will take you to recovery mode.
In recovery mode use volume keys for up and down navigation and power key to select. Still if you have any doubts Search for recovery mode in youtube

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.

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.
