Hi XDA Forums,
I have a problem with my Note 2 for some reason.
Let me explain you what is wrong with my Note 2
I was sitting down and watching a movie, my phone was right next to me, The phone randomly turned off and after couple of second it had turned back on. It had showed the first every screen when you turn it on "Samsung Galaxy Note 2 N7100". Now from there it keeps on looping the same screen over and over again.
I had done some research before opening this thread, I saw that some people said I should try factory resetting it from the recovery mode, I then tried going on the recovery mode, it was not successful, it had showed me the same "Samsung Galaxy Note 2 N7100" screen and then repeated to boot loop it self again, I tried going on the recovery a couple of times but it didn't let me go on it.
Next I had then downloaded the 4.1.2 Official Firmware from SamMobile to flash it to stock again, I had then tried going on the Download Mode, It goes to the screen for Download Mode, but when I try pressing up to continue from the warning message it had then rebooted it itself and made it self stuck on the screen again.
Basically, my phone is stuck on boot loop, It does not let me access the recovery mode and it also does not let me access download mode.
ROM Using: Tigra_RomV3 4.3 Based ROM
Kernel Used: The Kernel which comes with the ROM or Stock, I didn't change the kernel myself.
If there is a internal problem does that mean I wont get help from the Warranty because the phone was rooted?
hello,
just try to use the jig, it should work...
use it so your phone will be in download mode, then flash your rom
Do you NANDROID backup? Maybe you may restore it by custom recovery.
Second, remove the battery first for a while and retry to access the RECOVERY and DOWNLOAD mode. If not, try the suggestion up there.
Hi Guys,
've flash my Samsung Galaxy Note 2 N7100 to 4.4.2 KitKat it was successful, but after a few days my note 2 keeps auto shutting down randomly and sometimes I can't turn it on from sleep. I thought I've just missed something when flashing to 4.4.2 KitKat, what I did was to re-flash it and check if I've missed something but not. After I re-flash it, I've encountered this problem. I'm stuck at boot loop, I've done the Wipe process it was successful, but it didn't fix the problem, what I've noticed is when it's NOT charging or plug to PC it is stuck at boot loop, but when I plugged it to PC or charge it it continues loading the KitKat, sometimes prompting that it's not charging.
I'm wondering what could be the problem here. I've google any possible problem, I can't find any similar problem to mine. Can anyone help?
I'm still try any possible way to fix... HELP!

I exactly encounter the same issue on my Note II. It seems that the automatic reboot (then the boot loop) when the phone is unplugged is generated with apps (or system) using internet connection or the camera.
Please help ! :crying:

I had a similar problem with my note 2 N7100.
It used to reboot every 30 minutes.
The best solution was to reinstall the firmware using ODIN.
First you need to download the firmware from sammobile and put the phone in download mode and install it.
Hope this solution helps you too.

Thank you anish. I already tried this solution (with stock firmware and Cyanogenmod 10.3 &11) but it didn't work for me
The phone boot only happens when I unplug the USB cable and launch an app. If I do nothing after unplugging the cable the phone don't boot immediatly.

Hi guys ! I finally found a temporary work around to avoid automatic reboot. After multiple tests I noticed that the issue seems to come from CPU usage.My phone never went to deep sleep and often stayed around 1600MHz.
The work around was to go to Preferences > Performances > Processor/CPU > Strategy select "userspace" . The CPU goes down to 800MHz but I don't have any more automatic reboot when the USB cable is unplugged.
After reboot the boot loop is still there (so I need to put back in the USB cable to boot normally). I was wondering if the boot loop comes from the boot.img file...

Ive literally tried everything .even repartioned the phone . it works fine in recovery and download mode but as soon as i want too boot to android unplugged it restarts . when plugged it has no problem
Funny thing. I have a factory Sprint Note 2 with the latest kitkat updat and I am experiencing the same problem. Phone has not been rooted or messed with. If anybody come across a solution let me know. I booted the phone and unplugged the power button to verify and it does the same thing. Only stays on when in airplane mode or charging.
One more thing. I tried somewhat to do what was posted above about performance / cpu power. I put the phone in powersave mode and checked limit cpu and is is fully operation. problem gone. If I turn power save mode off I'm back to square one.
To late. Took a picture by mistake and phone jumped into boot loop.
i have GT-N7100 and same problem phone is stuck on boot loop when unpluged
---------- Post added at 04:22 PM ---------- Previous post was at 03:24 PM ----------
i just tought maybe it needs new battery. cause before i unpluged it it showed 67% then bootlooped 2x then i pluged back in and it shows me only 5%. i think its battery cause it cant dishcharge in 1 or 2min
My initial problems were that it would drop signal and show an x with no bars intermittently. then i started having problems anytime the phone demanded use. Picture, internet, video. tried a few things listed above. Still would go into a boot loop when not plugged in. Battery would charge normally and show it percentage like normal. It would reach 100% with no difference in charge time. When battery saver is on it would not have a problem unless I use an app that demands more cpu usage, network connection, battery consumption. Put a new battery and problem is gone. some people say the battery show swelling but my battery looks identical to the new one. no swelling and it is not deformed in any way.
It also solves the problem for me ...but i dont know what to do after the restart ...have u found a permenant solution

I was thinking. If you flashed with a bad battery whats there to keep it from affecting the flash / update. The stock system doesn"t allow an update unless the battery is charged. It doesn't know if the battery is faulty. Try to reflash after a new battery has been reinstalled and charged to full. It's just a thought.

Where is the Preferences section? I am unable to find that on my Note 2 settings.
Experienced the same thing and this is the first time I had this. I was playing a game after I fully charged my battery and suddenly it turns off. So I waited for it to turn on where I noticed that it keeps on turning on and off and stuck on the " Samsung Galaxy Note 2" logo screen. Then I tried several things like clearing the cache and dalvik but it just do the same thing. I re-flashed the 4.4 ROM that I was using but sadly it does the same thing. I then noticed that if I plug in the charger it works normally and does not boot loop. And as soon as I remove the charger it will keep on restarting on and off on that screen. I was thinking that it might be a hardware failure or the battery itself. So I went to recovery mode and unplugged the charger, it stays on. Went to download mode without the charger and it stays on. Freakin' weird. I am about to flash a different ROM and will wipe everything and see what happens...
Fully charged the battery to 100%, unplugged the charger and it started to boot loop again. I allowed it to boot loop once and immediately went to recovery mode and saw that my fully charged battery went down to 3%. Tried different ROMS (Omega, DN3, and Phoenix), I still have this issue. Now can use my Note2 as long as the charger is plugged in...
Change your battery and solve the problem ?

is it working fine after battery change? does it still get stuck in boot loop? mobile networks?
It works perfectly !
It's in a loop of starting up, loading to the home screen and then shutting down a few seconds later. While booting, in red text, the words "Kernel is not seandroid enforcing" is in the upper left corner. I tried to root it and it didn't work. I've tried a factory reset and still nothing. Now it takes me to the setup screen, yet still looping. I don't know what else to do and I need help. I've later found out that the text is normal, but since it's appeared, it is in constant rebooting.
Currently, I have a G928T firmware downloading from Sammobile which I hope I can use Odin to recover my phone. That's still got an hour left and I don't know if it will even work.
If there's anything else I can do, please say so, and if the firmware downloading is the only option, could you describe the process? I'd prefer that I not mess that up somehow.
After posting this (in the correct forum this time), I've calmed down enough to realize that there is another thread about this incident. I'll try the solution posted there for now.
That solution worked. I guess there's really not much need for this thread anymore, but if someone else were to have the same issue and find this thread, click here to go to the thread that fixed it.
As I read through your post I was getting ready to go and retrieve the copies of the files that I have and post them for you but I see that you've corrected your issues one thing I'd like to say to everyone if you do get into a situation where the phone is stuck since we don't have the battery pool anymore if you press the volume up/down home and power button the phone will briefly restart and then you can decide if you want to go into download mode from there or recovery or just let it try to boot up. Put that helps glad you got your issue fixed brother
Im facing some strange issue here since 1 month. After installing new rom (say phoneix or sultan) and after using for sometime UC brower gets force close error . And when i restart, the phone is stuck on boot animation, sometimes it automatically restarts and stuck on blank screen but notification light remains on. I only found solutions for that is to reinstall system again. Anybody is also facing some kind of this probs or got any other reason why its happening?
Its happening only during clean flash and not during dirty flash
