Bootloop - Galaxy Note 4 Q&A, Help & Troubleshooting

So a friend of mine owns a Note 4 N910H, and yesterday it froze while attempting to post online, so he forced it to turn off. It now refuses to boot, and keeps getting stuck on the Note 4 logo. Ive tried using recovery mode, and thats not working. The Samsung store at the mall told him that they weren't able to connect to their computer to reflash the software either. Any possible solutions?

My device is not passing the Note 4 logo neiter. I can enter bootloader and flash anything, but afterwards it is looping again... is it vibrating two times before restart?

[Q] Samsung Galaxy S4 sph-l720t (sprint) stuck in bootloop

I just got this phone alittle over a month ago. Today at work, my phone randomly shut down and started continuously restarting. The phone will vibrate and boot the logo, then turn into a black screen, vibrate again, and restart. I had not modified my device at all. Just downloaded your typical apps like anyone else. I already tried taking out the battery and letting it sit and booting in recovery mode and wiping the cache and restoring to factory settings. I also tried to use odin to flash what i think is my firmware onto the device. I wasn't able to figure out the firmware of the device before I did it so i sort of guessed based on the model. Though all i did for this is download what i thought was the firmware, put it in odin3.4, entered download mode and plugged my device in and let it download. I didnt do any rooting or enable debugging/disable debugging before i used odin. Did I miss a step? Does anyone have any suggestions of something I else do. I am so confused on how this happened to my phone!

Samsung galaxy s5 stuck on bootloop with no recovery mode?

Got a problem with my samsung galaxy s5. A few days ago it was working fine but occasionally randomly rebooted itself. It was be on a bootloop then it will boot up normallly after while.
Randomly the phone had ended up in a bootloop which it is not able to recover from.
i tried using the recovery mode, but that doesnt work. The phone will boot up the first logo after while, but usually it will boot up to a white screen, then will constantky repeat and never end. The screen is working fine, i do not know why it is booting to white screen.
My phone did that with stock ROM bootloop, I found a good ROM and cm12, soz I didn't answer your question that well. But to me the white screen your getting sounds likes you've deleted your boot loader, but don't take my word for it as I'm not a XDA developer, but I'd try and reload boot loader, but wait till you get a reply from xda

Galaxy Note 4 - No Power , Wont Charge

Hi All,
I've done a fair bit of Googling about this problem and I'm fairly certain my phones (hard) bricked, but I said I'd post just to make sure.
I have a Galaxy Note 4 N910F running a custom rom ( I cant remember which ROM, I think it was like Kyros Final Edition Note 5 Port or something) , I've been running it for a few months with no problem, last night I was uninstalling various apps from my phone, games etc... when my phone froze and turned off, when I turned it back on it was stuck in a bootloop, showing the galaxy note 4 screen vibrating twice and turning off and repeating.
I tried to boot into TWRP but it just froze on the Note 4 logo with "Warranty Bit Recover Set" or something along those lines at the top, when I took the battery out and put it back in, the phone would no longer turn on, nor will it charge, its completely dead.
I somehow managed to get it turned on again after a while, went into download mode and using Odin installed a stock rom, the install went fine however when the phone restarted after the install it said "booting to recovery" and ended up with a dead Android dude and a "no command message" , I got into recovery mode then and cleared the cache. Then I restarted the phone again and the same thing happened.
Now the phone wont turn on again, I've soft reset it, left it plugged in charging for a while and still nothing. Has anyone experienced something similar to my problem before? Any advice/help is much appreciated.
Thanks
Alan

Bootloop issue with G900V

I was using the device just fine, no problem. Then when I restarted the device for refreshing, it got stuck on bootloop, right stright to Samsung logo, not wait until the blue dot appeared, and it got bootloop after 1-2 seconds no more no less. The more scaring thing is that it completely got bootloop even when I attempted to boot into recovery mode, and I do have to plug my phone ( But at least it didnt bootloop when I was in Download Mode ). Yes, I did try Odin method, and it couldnt work. I tried the latest version, will try on older version to see if it works or not. The most weird thing is that the software at my Android before getting bootloop was G900F, and the back is still the same. I dont assume the back was resticked, but when it comes to Download Mode, it shows up as G900V. I dont know what to do now. Can anyone figure it out? I cant ****ing stand out anymore with Samsung old modem anymore. This is the second time after buying Samsung Galaxy Win. Ty

Note 4 Stuck in initial boot screen. Tried everything I could.

My Galaxy note 4 is stuck in that "Powered by Android" screen when booting.
Model Number is SM-N910C.
Download Mode is the only mode accessible. Recovery mode is not available now.
It worked just fine running Sweet ROM just a few days ago but randomly stopped working.
After trying multiple re flashes of TWRP, I eventually resorted to just restoring a system firmware image from SamMobile.
I have the exact same results as before, but now the recovery button combo does not result in any error. The phone tries to boot up normally and is stuck as mentioned before.
Plugging it in charging causes the phone to boot up and then get stuck in that screen again. This is incredibly frustrating.
Any ideas are welcome. Please help me out here.
