[Q] Not rooted Note 4 occasionally stuck in bootloop - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi,
I have a SG Note 4 (n910f), I have not rooted the phone.
Every once in a while the phone turns off and reboots, and then it reboots again and again, it's stuck in a bootloop. However when I wait like 30 minutes to an hour, it eventually succesfully boots and shows my lockscreen, at that point the phone works fine again.
It happens now nearly every day and is getting very annoying.
I only once flashed an original software update from samsung with Odin without voiding the knox warranty.
The only thing I haven't done yet is setting the phone to factory defaults. I'm going to try that today, hopefully it works, but I have a feeling that the problem is hardware related.
I can't get into recorevy mode, and I don't have a custom recovery and i'm afraid if I get that it voids the warranty.
What should I do?
I can't go to a samsung service point when the phone isn't bootlooping cause they'll say nothing is wrong, and if I do go there with a bootloop, it might fix itself again and they say it is fixed, though the next day it goes bootlooping again...
Edit: I can get into standard recovery when the phone doesn't bootloop. Just cleared system data and cache.
After I did that the phone got stuck in a boot loop again

Verizon Lg g2 stuck in bootloop

So for a few weeks now, my phone has been having bootloop issues. I've been trying to fix it on my own, but no luck so far.
I can get it into download mode. Up until I tried to restore it to its stock version via the User Tool, I could get it to the factory reset options, which led to the options to wipe cache, reboot, etc. However, none of those options worked. When I attempted to reset to factory settings, I got the "dead" green android with the red triangle. Then the screen goes black and starts bootlooping again.
Once in awhile I can manage to turn it on after having it turned off for hours, or even days and it works like normal, except that if I lock it or turn it off it will end up restarting and starting to bootloop again. Which is bad seeing as it drains somewhat fast due to being overheated while having the screen constantly on.
As for my experience trying to use update recovery, it gets to the downloading part then stops and gives me this message "[011.700.147.062.092]??? ??? ? ? ????". I don't even know if I am using the correct stock rom for my phone, since I only know its MEID and model name.
do u resolved this, i have the same problem

Sm-g900f (uk) galaxy s5 - arrgghhhhh

Can anyone PLEASE help??
My partner opted to do a suggested update on her S5, but didn't notice the wifi was off. The phone seemed to have done the update, but shortly after it rebooted itself, then again, then again. The frequency of reboot got quicker and quicker and now it loops between the Galaxy S5 splash screen and the SAMSUNG logo, but doesn't go any further.
I managed to boot the phone into reset mode, cleared the cache and then did a factory reset, but that did nothing to prevent the boot loop.
I then downloaded Odin (ver 10.3.7) and what I believed to be the correct firmware (G900FXXS1CPLV_G900FVFR1CPJ1_G900FXXU1CPIW_HOME.tar.md5).
Having checked the battery was charged, I followed the instructions of connecting the phone via USB, loading the md5 in the AP, checking Auto Reboot and F-Set time in the options and clicking the Odin Start button. I had removed the battery, replaced it and then booted it into the update mode (Power, Home, Volume Down, then volume up) with the screen confirming I was in the right place (....do not unplug.... etc).
The file loaded, (green bar at top of the Odin window on my PC) and Odin reported success. I then disconnected the phone, booted in recovery mode, reset the cache and then did a clear data, factory reset.
The same symptoms prevail, STUCK IN BOOT LOOP!!!!
The only thing different is that if I plug it into the USB on my PC, after a while the phone tries to turn itself on and goes into either a boot loop or freezes on the Galaxy S5 Splash screen or the SAMSUNG Logo.
I am charging another battery (just in case that is in some way to blame) and will try again to replace the firmware, but could I be missing something, do I need to do anything with PIT (I thought this was all taken care of by Odin using the MD5 file) or is there some other test I can perform that will show if the phone is fried???
MANY THANKS for looking!
ur going correct, try to reflash it again through odin and dont disconnect phone until it boots into system, it is taking some good time, so just wait and dont do anything this time like clearing anything or restoring. i hope ull get success.
THANKS - but...
Thanks Rayzen, I will try the whole thing again, but I think there is something more to this than a firmware fault!
There and gone again
OK, so on the 4th attempt I got the phone to take the firmware using Odin, it reported success and the phone rebooted itself (several times) and eventually appeared to boot to a new factory reset.
I put in a SIM card and entered my email and google account details and left it charging over night. This morning when I tried to use it, the screen froze and then it rebooted itself. Hey presto, the phone is back to square one with a boot loop.
ANYONE (please) got any suggestions?
THANKS
No one??
same here, same symptoms, same feeling.
when flash gone right... i feel lucky.. but for half hour only, rebooted and angain in boot loop.
I cannot even boot in recovery. flashed TWRP. from 5 boots in recovery only 1 success.
When trying to wipe phone in TWRP - it hangs.
still trying to install some other (custom) rom. still no success.
hope never dies
same things happened here! now cant get samsung galaxy s5 to boot...............
Are you sure your using right firmware? as it took me a few versions before it booted last time this happened?
Could any please confirm what is the right firmware for samsung galaxy s5 900F
It took another 6 or 7 attempts, left it over night and was about to trash it when it booted.
I then received a 'software update available' message and tried installing it. First attempt put the phone back into boot loop so I reflashed it again using Odin.
That worked immediately the over the network software update installed and now phone is 100%
Very frustrating but I got there!
glad you fixed it! ive tried three different firmwares and still nothing.
trying this one atm
G900FXXU1ANE2_G900FEVR1AND1_G900FXXU1ANE2_HOME.tar
oh and how long do they take to boot when there are sitting at the samsung glowing screen?>
I'm in UK and used what (I had to guess) was the best firmware.
I'll let you know which version it was when I get home tonight.
BUT I had all the problems with a single version and it eventually came good.
I read somewhere that overwriting a different core (from specific providers) with generic firmware, could lead to a world of pain until it gets full replaced... not sure if that's a good description (or has any fact to it) but it seemed to be re-loading and re-loading and re........ for ages, finally cracked it.
well mines booted now!but getting constant errors about samsung push!
If it'still booted, you'very made progress!
Push issues are mentioned elsewhere and can (eventually be sorted) but if you have a booted phone you should be able to get an over the air software update installed from the service provider....?!

S5 (klte) bootloop.. cant access recovery.

So, I wanted to get some ideas here before I install the required things to try and sideload the stockrom, but here is the situation..
The wifes S5 on Wind mobile (yea, freedom..) started randomly rebooting a few weeks ago, and up to a couple days ago, become more frequent. I went ahead and booted into twrp and did a factory reset. The phone is completely stock, except for twrp. We do have a nandroid backup on the sd card.
Anyway, the reset seemed to have fixed the issue at first, but shortly the reboots started again, became more frequent as time went on, up until today; wife comes home with the phone stuck in a bootloop. Won't go past the Samsung Galaxy boot screen.
I was going to re-flash the stock rom I got off sammobile or whatever, but the phone wont boot into recovery now. TWRP blue backdrop shows, then phone reboots 5 seconds or so later, and bootloops.
I'm out of ideas. I'll try and do an ADB sideload.. or, Odin, maybe. Luckily the phone is able to get into Download mode.
Could this be hardware related? I have a feeling there's some sort of damage due to her dropping the phone quite often. Never cracked a screen though. Amazing.

Bricked?

So. My Gf's Galaxy S5 has been wierd since an update she doesn't remember (Latest is May 2017?)
It has rebooted randomly, so ofc i blamed they battery, as it is 99 times out of 100.
But when a new one just resulted in a bootloop, i had to google and to they usual things: Reflash with latest Stock-fw, Factory reset, try the 2nd newest, FR, and so on.
I'we tried 3 firmwares now. (2x "nee" and 1x "vds")
Still the same loop, sometimes it gets to the Samsung logo, and boots for a while and reboots to the galaxy5 logo and freeze there. Right now i got " sa" from the Samsung logo, frozen.
Sometimes it reboots to black and wont start....
It doesnt feel line a Brick, since dl and recovery works, but it wont start....
May an custom rom and/or recovery help?
I got tools to open it, but i rather not, since you need to remove the screen to acces the PCB...stupid Samsung...
Edit/Update:
Flashed Twrp.
Cannot install the custom rom i'm trying, it freezes randomly. >_<

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
