Very unusual behavior Galaxy S6 G920F (Europe) - Galaxy S6 Q&A, Help & Troubleshooting

Hello guys ,
I am using rooted Galaxy S6 since 2 years , with a strange kind of rooting features , it means i have the SuperSU installled and
working for all apps , including Root Explorer and Titanium Backup , but i was never able to load a costum recovery such as TWRP or Clockworkmod.
Because i was to lazy to digg after the issue , reset and retry. etc.
Android Version : 5.1.1
Kernel version : [email protected] #1
Baseband :G920FXXU2COH2
After 2 years of problemless using , while set my phone for charging it entered a start screen with the samsung logo
and a red little writing message : Kernel is not seandroid enforcing.
I could enter download modus , try to reboot , every time the device either remains stuck on the samsung logo ,
either sometimes tries to boot the Android but remains stuck halfaway , sometimes with a loop af the bootmusic , the only way to
make it shut up was V- PWR-Home to enter the download mod. After a couples of tries i managed to enter the recovery screen , wiped cache and rebooted , same curious behavior.
After almost 3 hours of playing arround , try to charge , wireless or wired it works , but i never had the feeling that the device was real shut down and powered off.
I thought i would never be able to restart the device again. Somehow i thought to wipe cache one more time and then , from the recovery mod i choose power down
and then put it on wireless charging. After 45% it restarted itself properly and now it is online and charging .
Every advice or suggestions are welcome.
Thank you in advance.

[Q] Urgent: plz help:just installed custom rom "Adi's Sungsonic",keeps auto rebooting
i rooted my tab2 p3100 with the help of "Single Step - Philz Touch Recovery + Root" by Luigi2012SM64DS.
And installed a custom rom "Adi's Sungsonic™ HD Golden Edition V-6 ★][★DTS Audio X-Reality★][★MULTI WINDOW " .
The entire process happened as planned , installation waas succesful and it even booted and i set it up , played a song too; then i clicked multi window to check, thats when it got stuck and problems started.

By mistake I entered download mode instead of recovery mode, i panicked and pressed power button to boot; it booted , samsung screen appeared and lock screen but im unable to open it, instead it stucks and boots by itself . the same samsung logo coming lock screen which doesnt open and restarts by its own . Im very much worried , plz help. Im a newbie an its my first post so plz excuse me for my mistakes.

I've bricked my phone? I am unable to go to recovery mode! It is in reset loop! :v

I had installed xposed with some popular modules like Android L theme, Greenify, Gravity Box and ifont.
Today I wanted to unroot my phone (due to some reasons) so I just unchecked all modules from XPOSED modules list and restarted the mobile. After restarting I wanted to reset my phone so I went to reset my phone and then the **** happened.
Now it goes to reset screen (for 2 seconds) then in logo screen (for 3 seconds), then again in reset screen (for 2 seconds) and again logo (for 3 seconds) and again reset screen..... it is in boot loop!!! but this boot loop is extra ordinary :v
So after waiting for some time I realized that I have done something wrong so I decided to remove the battery and then turn on the phone but still same problem.
I have backup of my phone so when I wanted to go to recovery mode I couldn't.
Whenever I press volume up/down (both) keys with power button it again goes to that reset screen loop (instead of opening recovery mode). So please tell me a way to fix this problem.
Any help will be appreciated!
My mobile is "Qmobile Noir i9".

**I was using stock rom.
***I have cwm backup in my computer.

I Think This Will Solve your Problem
Flash this Rom Via Flash Tool
Rom Link : click Here
How To Use Flash Tool : Click Here
Cheers
ok I fixed the problem.
I turned off the device for two hours (the battery was removed too). After two hours I removed sd card and sim card and then turned on the device. The device turned on successfully!!!
The only problem I am facing now is xposed modules are still installed. The phone is reset successfully but modules are not uninstalled. My phone still have new font (which i changed with xposed), new boot animation!
I will now install the modules again and then uninstall them. I hope it'll work!
And the scatter file link is not working in the blog (the link you gave above)....

Stuck in Boot screen and download mode - NO recovery mode.

Hello i'm new on this forum,
I have got an Samsung GALAXY S6 ( SM-G920F ), a week ago i was using it and it suddenly shut down. and rebooted but got stuck in the Samsung Galaxy S6 Boot screen.
The problem is :
- I can only boot into Download mode
- booting into Recovery mode is impossible, i have tried all the possible ways.
I have tried flashing it with the plenty of stock firmwares :
- For most of them, it fails at the hidden.img
- I have found one that works great, Sucess at the end of flashing but after rebooting the phone get stuck in boot screen or downloand mode, AGAIN ... ( and the same happens if i unzip and remove the hidden file and then put back to MD5 and use it to flash ).
So, any solutions from you guys ? I have heard that since it's going into download mode or boot screen it's not a hardware problem and it's only "bricked". have been reading that since it's booting, it's better than not booting at all.
I also heard that this problem might be resolved by rooting the device.
HEEEELP !
PS : My phone shut down suddenly, so i'm not sure the developper mode is activated or the USB debugging is on...

Samsung S8 stuck at GALAXY S8 boot screen ,And no recover access after flashin stock

Hey Samsung users.
my case is a bit weird.
i bought my s8 running nougat used it for 2 days and it was all good , so i received the Oreo update and updated it using the over the air when I received connected to wifi.
my phone started to reboot randomly even for 30 times per day , i tried several things like wiping cashe and the only solution that reduced the problem was uninstalling my installed apps. basically normal apps like facebook , whatsapp , spotify ,and even stock apps like calculator and music player.
today as usual I woke up picked up my phone and it started rebooting so i uninstalled some apps but it kept rebooting.
sometimes it reboots and get stuck at GALAXAY s8 boot screen [ not samsung flickering screen ] and all i had to do to overcome the boot loop is pressing and holding volume down and power button.
but one time it got stuck and boot looped once and for all. I tried to press volume down and power button to make it reboot again and overcome the bootloop but it rebooted and got stuck at the bootloop.
I tried to access recovery but i couldn't access it.
I can access download mode only.
my phone switches on itself when it is plugged in to charge , i can't turn it off completely to charge it while off.
I reflashed stock firmware and it succeeded using odin but the bootloop is still there.
please help me with my problem.
any slight help or idea would be a life saver for me.
sincerely,
Zack.
