bootlooping even after stock fw - Samsung Galaxy S7 Edge Questions and Answers

hey, i was hoping that somebody could help me determine the problem with my s7 edge.
today i turned on magiskhide for an app and restarted my phone, after that it restarted itself like 5 times then boot properly for 30 seconds or so. i tried flashing updated TGP with BL and CP but it didn't help. then i tried flashing stock rom with odin which also didnt help at all. and lastly i tried an aosp rom but the problem remains unsolved.
the phone restarts itself, then stays booted for a while, then it gets stuck alongside with a black glitch on the display. can someone help me determine the cause of this? thank you a lot for your help in advance.

N910G restarts multiple times after flashing with stock rom from sammobile

Hello,
I have been using my N910G with DN5 rom by Dr.Ketan. Later when I had issues like device lagging, I flashed it with the stock rom from sammobile which is the australian version. BOH4
Now, everything seems fine, but the device restarts on its own, sometimes just gets stuck and I have to remove the battery and start the phone again. Most of the times, it gets stuck, vibrates twice, immediately restarts.
How else can we fix this issue? Please help!
Same like me,and it's usually appear kernel panic after the device restart..im using australian versiol COL3. Anybody can help?

N910F - Heavy problems (bootloop, but no real bootloop)

Alright so a while back I created a post here about some problems I was having with the stock rom I was running back then. Got some answers (thanks btw) and after some more problems I finally was able to flash Alexndr rom, but the problems were still there (random reboots, battery was draining hard and died at 25%, slow). I was told that the reason for these problems were that I didn't install a different bootloader, which was mandatory. I have been busy the past few days so didn't really have any time. But this morning my phone suddenly had a random reboot and weirdly, when it rebooted a factory reset was done. So I decided that it was time to install the new BL, but ended up flashing the wrong one so got into a bootloop. Then i flashed it again with the right BL, first it seemed like there was no bootloop because i got into the regular screen (choosing language etc.) but suddenly it started rebooted, and it didn't stop. It always gets to the language screen, sometimes to the wifi screen but after that it still reboots. Because i really needed my phone to work i flashed the stock rom again, also a bootloop.
So i hope you guys have any ideas how to fix this, because i have no clue what to do. And i really need my phone because my sister is in the hospital and i need to be able to get calls.
Thanks in advance.
This is the stock ROM btw: N910FXXS1DPC2 (German, android 6)
AND BUMP!!
Really in need for some answers

Help - Freeze / Reboot Issues G935F

Hope someone can help. I had an issue with an app the other day which I think caused my phone to overheat.
Since then I have had a major issue with the phone freezing. I tried to install stock through odin which was fine but the phone freezes during the boot logo sequence, and the stock Rom won't load.
The phone freezes in the Rom, recovery and when booting.
I have managed to install lineage Rom as this doesn't take long to install or boot up. So I have the Rom running for anything from 10secs to about 40secs then it freezes and eventually reboots.
I have had red messages come up saying cannot mount or demount data and system when factory resetting when in recovery.
Is it a faulty part inside or does anyone have any ideas on what I can Do?
Thanks in advance.

Bro post in s7 edge help section, this is for news, guides etc. Btw you can try smartswitch emergency recovery, put your serial no. and model no. there. If it fails too then reflash stock rom with normal CSC and repartition ticked in options, it will delete all data, so back it up before. If it still freezes and reboots after fresh stock rom install, then there is surely something wrong with your phone.

Samsung Note 4 N910F is not stuck in bootloop, still doesn't really boot

Hey everyone,
I have been looking around online for several days now, but haven't been able to find a description of the problem I have with my n910f nor a solution.
When I got the phone it was stuck in bootloops and so I though it was soft bricked.
After I installed the custom rom and the latest version of TWRP via Odin, I thought that the problem was fixed, because the phone booted and I was able to start the configuration of Android (where it asks you for language, time zone etc.)
However, the phone turned itself off during this process. So I wiped everything and tried again, the same thing happened.
I then flashed it with Lineage, but it would turn itself off even before the logo appeared.
Then I flashed it with Ressurrection ROM, but again, the phone turns itself off during booting.
I can access download and recovery mode without any problems, I can flash roms and Odin works like a charm. I also used 2 different batteries.
Does anyone has an idea what I could try? Could it be the version of TWRP I am using (3.0.2.0)? Or is it a hardware issue?
Thank you!!
Hi, I have this exact same issue with my N910T and so far haven't found a solution to this. I really love my Note 4 so I'd like to know if this issue can be solved or not. I event went to a supposed repair shop and they couldn't figure out the problem, guess they weren't that good.
Sorry to hear this.
I have found issues that seemed similar, but not quite the same, and people hinted that it could be a worn out motherboard that is causing this top happen. But before I open up the phone (at the potential risk of breaking at least the screen) I would try everything else.
Or is there a way to test whether the motherboard is defective?
Its the plague of overheated, worn out emmc memories, sadly. Once it happen,the only way is a new/used motherboard,prefferably C model.
eMMC failure, snapdragon models are susceptible to this.

I suggest flashing stock rom with Odin after wiping your whole device in TWRP. I've had the same thing about 2 months ago.
Hey,
thank you for your responses. Yes, I read a lot about it being a motherboard problem.
I got it to work now thanks to this post: https://forum.xda-developers.com/note-4/general/downgrade-official-mm-to-kitkat-t3383885
First nothing happened, but after I flashed Modem and the original Bootloader again (after installing the rom) the phone turned on and I was able to use it for a while (20mins maybe). Then suddenly it turned itself off and stayed on the "Samsung Galaxy" screen for a long time.
Apparently a lot of people are using Wakelock and it seems to be working for some of them, but that seems to defy the point somehow.

Do you by chance happen to have a copy of that stock rom? I have the exact same model I need a copy since my computer crashed and I lost the one I had.
wenergys,
latest stock here : https://www.sammobile.com/samsung/g...e/SM-G975F/ZTO/download/G975FXXU8CTG4/357253/
