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

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 ?

Hello there
I own Redmi 1s. I have been using the phone for nearly 2 years now. I currently had Cm 11 installed on my device. Today while using the phone, my phone shut down on its own. A few seconds later the MI logo showed up on the screen. It lasted there for a few seconds and then went off again. The same has been happening for over an hour now. The battery percentage before this happened was over 50 %. I have TWRP installed, i tried to open the recovery. The recovery opens up but the phone shuts down on its own within a second and the MI logo shows up again.
I can't figure out what to do. Please help me. Thanks
I removed the battery when I saw this problem. The moment I put the battery in, the phone starts up on its own. This is pretty different as the phone didn't start on its own when I used to remove the battery in previous cases. In this case it starts on its own and the MI logo keeps of appearing and disappearing.
If you can get into recovery, you might like to try clear cache and data or even a factory reset (means sacrifice all data) and see. If still keep restarting, might be time to flash back the stock ROM...
hello there,
Am using mi max (hydrogen) since its launch. 2 Days ago when i was using my phone at midnight its screen suddenly went off

waited for 3 hr again booted it same issue is there
please someone help me!!!
at least make it workable so that i can exchange it!
A month ago, my Xiaomi Mi Mix 2 randomly started restarting and wouldn't stop. I can't access anything. I can't go to FastBoot mode, it would just restart again. I only now just bought an EDL Cable thinking it would fix things. It allowed me to go to FastBoot Mode but doing anything still results in my phone restarting. I want to "Connect with MIAssistant" because I still think I am able to keep my important data inside, but when I try to connect to my PC it reboots again. I haven't tried to wipe the data yet, but I am saving that for last if there really is no other solution.
Does anyone know what I can do?
I'm in a similar situation, fastboot I'm stuck for days now.
unlocked/magisk/ArrowOS/NO Gaaps/Fastboot only/Dead battery lest plugged in.
Please Advise
Since a few months, I'm facing this problem. The phone is working OK when I can get to the system, but If I turn it off or the battery runs off, it gets stuck on a loopboot: the Mi logo shows and restarts itself after a few seconds. Can't access the recovery mode (it just restarts again to the Mi logo), fastboot works tho'.
The only way I have to get to the system is to start the Fastboot Mode, keep the phone on it to drain the battery and once it's empty, plug it to the charger and try to boot 15-20 times until it magically works.
I've never unlocked the bootloader or tried to install anything, the ROM and Recovery are the Xiaomi's stock EEA. I'm on MIUI 13.
Any ideas about how I can fix this weird behavior? Anybody has faced the same problem?
Thanks for reading/helping and happy new year to you all!

Nope. One day it turned off and I never could boot back in again. Sorry.
