S7 Stuck in Bootload / Updating

Hi all,
since one day i´m totally wrecked up with my SM-G935F. On Monday morning the display was frozen. I looked in some forums and used odin to flugh the newest version (7) to the phone. After clearing the cache it worked quite well for about 3 hours then freezed again. Since that i´ve tried so many options, all leading to nothing ;( I´m quite sure that there must be a solution and hope for your help.
The actual status is:
The phone shows the Galaxy S7 Edge screen, then the "Installing system update". This crashed every time (no command) and then a black screen is shown with some information in the upper half:
No Support SINGLE-SKE
Supported API:3
# Manual Mode #
-- Appling Multi CSC --
Applied the CSC-code: DBT
Successfully applied multi-CSC
Successfully verify for dmverity hast tree
Sometimes after waiting it jumps to the "bootloader". The normal way with the volume up + power+ home is not working at the moment or i´m doing something wrong.
I´ve tried a few fixes:
-> downloaded the newest Firmware, an older version and the oldest one from sammobile and install via odin
Normal install in AP via Odin stuck an recovery.img​I renamed the file without md5, open it and extracted the files. From there i tried to single upload them (boot, system and recovery) It freezes at system...​
-> flash home file first with odin
it stucks on RQT Close and don´t finish​
-> install new firmware via SD Card
frp lock denied the installation. Get error: E: signature verification failed​
-> samsung smart switch and kies
both not working. I´m not even able to make the software initializing because it tells me that my phone (SM-G935F) is not supported... WTF....​
-> install CWM recovery via adb
I´ve tried to install an other revocery tool without success. I tried the ways via Odin and adb, both collapsing with the error of activated frp lock​
-> TWRP recovery via adb
Same like CWM. The Binary Upload is denied trough frp-lock​
-> Whipe cache from fastboot
I whiped the cache several times without anything changing​
-> factory reset from fastboot
It says that factory reset was successful but data could not be wiped. It also changes nothing....​
From my nooby perspective i would:
-> unlock the frp
-> install custom recovery
-> unlock signature validation
-> install via adb or sd card the newest Firmware
-> lucky guy
I´m really depressed/sad right now and have no idea what to do next. I spoke with samsung service and they told me to send them the phone so they can repair it. I hope that this is not ne final solution...
If there is any possibility to get the phone back to factory reset or any other working system i would be soo glad.
sorry for the bad english, it´s not my mother tongue
Thanks in advance and beste regards

LOL, didint read all but the part where the phone freeze after few hours on MM or even on clean Nougat firmware its a big sign that the problem is with hardware, just send the phone to Samsung so they could fix it and move on

I actually did. From my perspective there was no other way so i send it in. Really unhappy with this solution but i hope that Samsung Support will repair it. Maybe i was too naive with the android phone. i thought that i where able to totally delete and reinstall the system like i do with my computer. Now i will look for a good backup solution for the future ;D
Thanks in advance

I think you messed up your phone somehow... certain steps you described do worry me what you might have done.
Did you root/unlock your phone before? If yes, Samsung will happily return your S7 without even touching it.
Kies & Smart Switch do not work on rooted phones. Exception: Emergency Software Recovery and Initialization
Did you try flashing all four files (BL, AP, CP, CSC not HOME_CSC) in Odin at once? Did you try another PC / USB port?

ByPass FRP Samsung Galaxy S8 need help

Hello guys. I know there are many topics about this, but I need a help about my Samsung Galaxy S8 (normal one, not Plus or Edge) G950F.
I tryed many method and I saw many videos and guides, but still it doesnt work.
My Galaxy S8 is brand with Tim (Italy) so I dunno if this could create issues or not.
I downloaded Combination Firmware 8.0 but I always have the error "SW REV. CHECK FAIL (BOOTLOADER) DEVICE: 2, BINARY: 1" on Mobile and Fail on Odin... this just can mean that the Combination Firmware isnt the right one.
I downloaded the right 8.0 Tim Original Firmware and tryed with Odin. It pass and everything go well, but still ask me for the old Account Gmail to verify the Account etc even if Odin did good.
I guess that I need to use that Combination first and put USB Debug (as I'm seeing in many videos) but I can't put this Combination Firmware for the error I said above.
What can I do? What is the right Combination file for a Galaxy S8 8.0 Tim (Italy)? I can't now naither turn on the device because it says to me in loop "An error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC Software" in a green screen.
Thanks for any help you can give. I just want use back this mobile.

Did you tried to boot in download mode and then use smart switch ? Smart switch can recognize a phone when you boot at recovery. Then try to repair.
Concerning the combination this error mean that the combination file are too old. I had the same issue long time ago ( Device 2 Binary 1).
What mean the Google Gmail thing ? At boot they ask you the mail ? Why don't enter it then ?
Tell me if something worked. Try to find a newer "combination".

I can't enter the Account Verification because the one who used this phone wont tell me the email and psw for it (he was the partner of my mom, but now they fighted and my mom wanted back her's phone.. but now, for vengeance/spite he wont tell us his data). I knew about Combination was old but where can I find the newer one? I am surfing on internet and can't find the right one I tryed many). My Firmware code is 8.0.0/R16NW/G950FXXU2CRED so I need a Combination Firmware eligibile with that.
I cant access the Device to install Smart Switch etc.

You don't need to access to the device. Just download the Samsung utility on your computer and connect your phone thought the download mode.
The name of the Samsung thing is Samsung Kies or something like that. Search for it.
And actually I never saw a phone asking for account verification ... I can't really help if this method don't work.

Or, flash twrp. Obviously the warranty will trip. And then delete everything, also the system. Then install back the firmware through Odin

The combination firmware needs to match the current firmware of the phone. Example if you have CRC7 then you need combination firmware CRC7

Please help, can't find combination file for sm-g9500 for latest upgrades. Firmware G9500ZHU2CRE1

[SM-A500FU] quasi soft bricked ?

Hi,
I have attempted to update my device to Android 6.0.1
- grabbed ROM from sammobile.com
- put device in download mode
- used ODIN by just loading the .tar.md5 file in AP and hitting start
ODIN spat something like "Write operation failed" just after this "hidden.img.ext4" file.
Googled a bit and it seems that deleting the "hidden.img.ext4" from the tar would be all that is needed.
But...
ODIN would not start flashing with the new .tar file. So I have rebooted the device and bam!
Code:
The device now reads "An error occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software)
So I went on and installed the Smart Switch app for the emergency recovery function. Tried with 3 versions of it 4.2.18xxxx - 4.1.16xxxx - 4.1.17xxxxx. No chance in the first version, the last two versions would allow me to input the device information (model and S/N) but both spat back at me
Code:
Smart Switch App says "SM-A500FU does not support initializing. Please contact our service center"
So, I am now stuck with a permanently turned-on-screen device that would not go into download / recovery mode (but it does reboot to the same screen), the battery is non-removable, and I also got some Z3x samsung tool thing at hand, hmm... Any chance for me to put it back into download mode or is it good for the recycle bin ?
Thank you

How to unbrick?

hi, my s7 edge is on the emergency recovery screen after boot, already tried Smart Switch no success..
already tried install a lot of twrp versions by odin, no success either
tried to install some roms for my phone and got some error, the latest error was saying device 5 and binary 1 or 4 sometimes, i guess this is because my phone was at 8.0 and some rom i got is older right?
So, how can i find a rom with binary 5?
My model is SM-G935FD

This binary error says your bootloader has been updated. The only way to solve this is by installing the latest version of stock rom via odin.

Hello all,
I did something similar i add last update with odin but after restart i get error can't update software. I stupidly turn it off and now is in brick mode I mean nothing happent when i press all possible combination. I order JIG but unfortinaetly did work for S7 it works for my other samsungs. I probably will make my own JIG with 400Kom .
I just thinking any other hardware way to start it.
When i connect to PC i hear the sound connect but after couple seconds disconnect.
Any suggestion what else I can try

S8 stuck on boot loop, recovery mode. (can only access download mode)

so yesterday i decided to restart my s8 cuz it feels like there are times the phone screen malfunction like while i was playing the control pad got stuck for 2-3 seconds (tested with 4 games also same result) and i proceed to eat my brunch while i wait for the phone to restart completely.. after that i noticed the phone is stuck to boot (Galaxy S8 powered by android) after 1-2 minutes the phone will proceed to recovery mode (no command ) then its menu and after 7seconds the phone will restart to boot again (infinite loop)..
i tried to flash it but i really dont know what build or firmware should i download..
idk if i already soft brick it but after flashing it the odin always shows a fail result.. (but it is still in boot loop and can still proceed to dwnload mode)
i saw this message in phone while in download mode
SW REV. CHECK FAIL (BOOTLOADER)​also saying device 12 binary 11 (i researched about it and found that my phone is up to date abd the firmware im trying to use to flash is old, the thing is i dont know what firmware should i download))
My question is can this be saved by flashing it with latest firmware? and if its possible can you send me a link of the phone firmware that match to my device.. i already searched in sammobile and the current firmware for my phone there was the february 2021 (02-21) firmware..
since i cant check my build number or anything (cuz of the boot loop).. ill justput here the details about my phone..
*model : galaxy s8 (SM-950FD) ,dual sim,64gb rom 4gb ram, exynos variant
- i still have the box of it.. (bought the phone december 2017)
*all i know is that my phone is up to date (last month i checked it settings and the phone says it is up to date)
*last year (June 2020) - the phone screen starts to flicker but i can still use it by turning on the AOD and set the brightness to 50% then the screen will go back to normal
*July 2020 i tried to reset my phone hoping that the screen will be fixed, it went smoothly in a week (no flickers even @low brightness) and then after that the issue goes back again so i just keep it that way and back to Turning on the AOD to fix it.
*last week of Oct 2021- so for after a year & 4mos. and already used with the flicker issue. the fingerprint sensor starts to malfunction (so sad i cant access the samsung pass anymore)
my last restart of the phone was this time.. and time to give up with that fingerprint issue
* i flash it earlier today this is the firmware i downloaded//
SM-G950FDPhilippines (Open Line)2021-02-02G950FXXSBDUA3Android Version 9
i tried that firmware cuz im living in the philippines plus it is dual sim (i presume its an openline) however odin tells that this firmware is old..
that is all i know about my phone.. let me know if you need more details about it.

device 12 binary 11 - does mean you are flashing older firmware than what is on your phone.
device 12 means your on binary/bootloader 12 and binary 11 is firmware trying to flash ie: G950FXXSBDUA3
this may be the latest version G950FXXUCDUD1
you can use this pc app to download latest firmware. See last page for download link

You may have to install some visual c++ files if your pc doesn't have them They can be found on microsoft website.

In using Odin
Home_CSC file will keep your apps and data ie: all apps and data that you have installed.
CSC file will wipe all data and apps ie: same as factory reset.
