I just tried to use this method and it bricked a Note 8 N950U1.
Here's what I did:
I had V7 bootloader first, so I flashed a V8 firmware (BL, AP, CSC) and it booted up fine to the OS.
I was having some issues with Odin so I decided to turn on USB debugging used ADB to boot into download mode (adb reboot download).
I used the N950 combo firmware to flash under the AP tab, unchecked the auto reboot.
The flash went through and said PASS and I went ahead and manually rebooted into download mode until....
nothing happened.
Just shows a random bar fast flash only when trying to get back into download mode. Will not power on or show recovery, bootloader, OS, or even charging icon.
I work at a phone repair shop so I decided to open the device and unplug the battery like was said on this forum, but unfortunately still no success. No QL download mode either. Not sure if I did something wrong or just one of the unlucky ones.
Sorry 😞 sounds like one of the 10 percent brick happens to
 
I used the OTA zips for S8+. And now when I turn on my Note 8 the boot screen says it's a S8+. No issues with that. I think it's funny. My Note 8 was to be S8+ and we call them smart phones. haha. But thank you for all the work you have done with the Samsungs. I've been using your work with the S5 and so on. Much appreciated and respected

Im pretty sure an ota zip for s8 that was oreo because that's the only time it worked would not flash on your note 8 you must be confused with system image
 
I mean the S8 Plus. But here's what my Note 8 does when I turn it on. And I'm not genius at all this. But I do try and use everything you make for safestrap. This is what I mean. Sorry I'm just a novice at it. But I really do enjoy doing this. So thank you again. Very much appreciated.

On step 3, I get the error: "
'adb' is not recognized as an internal or external command,
operable program or batch file."

How should I fix this?

Right click in the folder containing the bat file or cmd file and click open command prompt then type the name of the bat file or cmd file to run in the command prompt window and click enter. In this case N8-SAFESTRAP.bat then hit enter or you can open a system command prompt and cd to the directory containing the bat file

I've tried doing as you explained, and the text in cmd becomes green but nothing else happens.
Meanwhile, my phone screen goes into "factory binary".

Other things I have tried is double clicking on the bat file itself, and that's when I get the "'adb' is not recognized" error.

Any suggestions?

    Guys, I am pretty new to this stuff. I tried to root my SM-950U US Verizon model using safestrap. GUI method did not work. It will always wait at the message saying that downloading combination file. Command line methods seemed to work as it did progress with the succesful status. But now m phone can not be switched on. Its not even charging. I am not sure if I missed any step inbeween. I tried pressing "power button + V up", "power button + V down", "power button+ bixby button + V up", "power button+ bixby button + V down" etc. Nothing helped. What can I do next?
    This is the Note 8 thread so do you have a note 8 or S8? because in your model description you dont say. Also try the cmdline method

    I was on the latest stock firmware. Bootloader version was v8 as far as I remember. Another update. When I hold volume up + power button, I horizontal line flashes and goes away instantly. So something seems to be happening. but phone is not switching on.
    just check back from time too time if there are ever files available I will pass them along to everyone

    Before Starting This Process Get A USB2 Mini Hub You Are Most Likely Going Too Need It. Do Not Come In Here And Post This Is Not Working Until You Have Tried It With The USB2 Mini Hub!

    Disclaimer Please Read!!

    This may brick your device there is a problem especially with s8 and note 8 models where the tz partition becomes corrupted and on some occasions after flashing combination firmware your phone will become bricked and as of now there is no way to fix it. There is no way to predict if it will happen. It doesn’t seem too happen very often on s8+ but it does occasionally happen on the other 2 models so do this at your own risk. I would say it probably happens 10 percent of the time on s8 and note 8 especially when on bit 6 or higher firmwares. S8+ it rarely happens too but it still may. If you take the risk and it happens do not pm me asking how to fix it as of time I posted this there is no way to fix it

    Please Read Notes

    OEM Toggle Does Nothing On US Model Phones

    You will most likely need a USB 2 mini hub for Odin to work if using windows 8 or higher. I would temporarily disable windows defender or antivirus software while performing the procedure with your computer.

    You cannot have root on any rom except a nougat rom also flashing custom boot images cannot be done or using systemless magisk. Hiding root or running modules cannot be done. There is no oem unlock and even if there is you cannot unlock your bootloaders or run any aosp based roms.

    You can be on any firmware to achieve safestrap but to run a rooted rom you will be limited to using a special nougat android 7 rom. You can have safestrap on pie android 9 which gives you some ability to modify system files flash zips etc and have access too data and other partitions that are normally blocked but you can not run root on android 9 because root on android 9 requires a modified boot image

    Anything here with a .7z extension will get unzipped before using
    Anything here with a .zip extension will get flashed a zip in safestrap
    Anything here with a .tar or .md5 gets flashed in odin
    Anything here with a .img extension gets flashed as image in safestrap

    You guys could try flashing the s8+ system image on the note 8 and see if that works. I know the note 8 system image will boot on the s8+ so it should work vice versa. Xposed works on the s8+

    It has the battery bug that only charges at 80% after installing the root

    If you look in the s8 threads I have a hack to pass the 80% charge limit It is not a bug It is a safety feature so you dont blow your fingers off
