Soft-Brick - S6 G20F

Hey everyone,

I have first tried to update my cellphone both directly via the phone itself and smart switch with no success. I have no idea why these two didn't work and because I am a very stubborn person I have googled the issue and found out that I can flash a firmware via Odin. Which I tried as well.

My old firmware was G920FXXU1AOD4, I tried to flash the version G920FXXU2BOGG.

Sadly, the result was this :

<ID:0/004> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

I am now unable to reboot my phone properly. I have tried to use Smart Switch to use the emergency recovery but it seems like it doesn't recognize my phone so it's not working.
I have also tried to flash a recovery system called twrp but it didn't work either and wouldn't let me enter the recovery system.

I have no idea what to do anymore. My phone is a week old and I feel really stupid for ruining it because I was stubborn and wanted it updated. I am a rookie with flashing, rooting, etc.. I have never done this before.

Any idea of what I can do ? Thanks a lot for any future help, you have my phone's life in your hands and I couldnt be thankful enough if I manage to save it thanks to you all.
