Note N910G very long reboot - Galaxy Note 4 Q&A, Help & Troubleshooting

I just bought a note 4 N910G .... I installed TWRP and flashed a custom rooted rom marshmallow... I noticed reboots are very very long (whatever types of reboot; normal, recovery or download mode)... I don't know if this happened because i flashed TWRP.
So, i flashed back stock unrooted 6.0 rom but the pb still persists... reboots take like 5 - 10 mins .... it has black screen thinking that it is turned off (pressing power button or any button does not do anything) but if i wait like 5- 10 mins, it actually reboots..
any clue?

Random reboots and won't power off.

So here's the story.
I have a Note 3 I acquired that was in pretty rough shape. According to the person that gave it to me, they had tried to flash a rom that was unstable and crashed the device causing a boot loop he couldn't recover from. So he reported it lost and got a new one.
The first thing I tried was installing stock firmware using odin. This at least allowed the phone to fully boot up. But, it would still restart after about 10 mins of usage. The next thing I tried was flashing TWRP on to the phone and doing a complete wipe of the phone. Then I flashed the stock firmware using odin.
This has brought the phone more or less back to a usable state. However, there are new problems.
The phone reboots at random. Usually after being on for an hour or longer. Also, the phone won't power down. When I long press the power button and select power off, the screen shows that it's powering down. The phone stays on the power down screen for about 2 mins then the phone reboots.
I've tried a factory reset and reflashing the stock firmware.

[Q] Sudden shutdown, phone won't boot.

I had just finished flashing and configuring crash rom v19, when my phone suddenly powered off.
Now it's not the first time I flash a new rom to my note 3 by any means, but this is a first.
Now my phone won't power on if not plugged in, and even then it powers on for less than a second, long enough to see the battery charging picture or the note 3 logo.
Recovery won't boot, but download mode works flawlessly, I pulled out odin3 with the stock ROM for my sm-n9005, checked the regin was right and everything, and after flashing using odin all I got was my phone rebooting over and over again trying to access recovery, then it booted no problem to the samsung logo, played the tune and even showed me my lockscreen for a second, and it's back to rebooting itself every 3 seconds.
Anybody have any idea what I'm facing here?
Edit: First thing tomorrow morning I'm going to take it to a store to try a new battery
@E-Chan42.
You can try this out.
I am not sure will this fix your problem.
First, charge your phone for 3 hours. Second, hard reset your phone then flash Stock firmware using ODIN.

I've had my phone plugged in for a short while, but since it keeps vibrating, showing an empty battery picture turning off, vibrating and so on every second I'm not sure charging will actually difference to my issue, still thanks for the input and I'll give it a try.
Ohm....
Then I guess it must be a Battery issue.
Give it a shot. Let's see if that works.
Took it in to my retailer and samsung guy restored the original ROM with Odin just as I did, when it didn't work he sent it off under garantee, thanks for your help! I'll update when I get a word back!

Bootloop and "erasing screen" after flashing stock european firmware

Hi guys, I have a big problem: I was testing Android 7.0 from GtrCraft, but seeing problems with my SIMcard, I wanted to reflash the stock firmware.
Well, after flashing I'm stuck in a strange bootloop that keeps "erasing" with the green robot screen and reboot. I can do nothing. I reflashed, ri-reflashed, tried twrp but it gives me many load errors and reboots. I tried power off, but it stucks anyway on erasing screen. I'm desperate, I don't know what to do...
EDIT: Solved, I forgot a sparsechunk

I had similar issue. To ensure you don't miss anything when flashing stock rom, use Rsdlite

Samsung Galaxy J5 starts to go green after Smart Switch PC update.

I installed the 6.0 Marshallow Update on my Samsung Galaxy J5 Smartphone from Smart Switch on my PC. At first everything was OK. I plugged it, and it started downloading. Nothing unusual. When it ended, it said that the phone is restarting, so I should unplug it and plug it again, to see if it worked. The first unusual thing was that the phone didn't restart. It was just turned off. And I passed that because I thought I misread. So I unplug the phone from the PC and try to power it on. This is when the REAL weird stuff comes. At first, the "Samsung Galaxy J5 Powered by Android" logo shows up. Nothing special. Then a yellow-blue line shows up below the logo. I don't give it enough attention. After that, the screen starts to go green. Slowly turning green. . .The logo didn't disappear. My first reaction was to remove the battery, wait 10 seconds and put it back. I now try to charge it, to see if it happens again. AGAIN THE SAME! The yellow-blue line shows up, the screen starts to slowly turn green. I then wait to see what happens. The screen goes green. Completly. The screen needed a few more seconds to turn COMPLETLY GREEN. But I was soooo scared I took the battery and the charger off. I put it back up but this time, I wanted to go to recovery mode, so I can simply click "Reboot Phone". I couldn't. There was nothing I can do. I now have the phone without the battery and I want to know what is happening and how to fix it. I am really scared so I need help ASAP!

Hello!
I think you flashed other firmware than your phone model. Thats how it happened on my J500FN when i tried 6.0.1 firmware from J500F since J500FN didnt have official update.
Download a firmware for your phone model, 5.1.1 or 6.0.1 and flash through ODIN, then the problem should be gone.
This happened on my phone when I put 6.1 on via odin but then I simply tried a different recovery and the recovery was the problem
John
Anyone know how to fix this problem? I cant use odin because it wont let me go to recovery or download mode
This is happening to my phone with the exact same situation, but now I can't seem to connect to the pc with the cable - what should I do?

It happen because you use latest odin. flash again using odin 3.07 and see how it goes. It fixed mine. Had to double flash. First flash was giving me green screen. It won even pass the bootloader. Then enter download mode and reflash it using odin 3.07, it works like a charm now.

It's happen when you flash ur custom rom (only for bootloader lollipop) using bootloader marsmallow. The solution is ur phone must be support the requirements of ur custom rom.

After Logo black screen, no root, stock rom 4.4.2

Hallo,
i hope someone can help me here.
After a low battery my phone doesnt turn on any more. After some research i thought it might by the "death battery problem". So i but the phone on Laptop Charge port for 6 hours and i got it booted in to system.
But only for some seconds and it turned of again. So i decided to buy a new battery. Installed it and tried to boot. Sometimes it bootet in to System, sometime just got Blackscreen. I tried hard reset in it showed some errors. That was some days ago. Now it boots and everytime blackscreen. I tried also longer presses like 10 secs and 60secs. I tried fast press for hard reset with boot logo. I have no detection on Windows. I never rooted the phone and it has still stock rom. Must be the latest kitkat 4.4.2 i guess. I checked every cable. No charge led or logo.
Hey dude check out my video https://youtu.be/rpmbk9RFE_U there is step by step instruction how to reflash your rom... Just watch im here for any questions.
