If you flashed a stock firmware successfully it will not boot into twrp, flashing a stock firmware will install stock recovery, which means the stock firmware did not flash properly. Have you tried smart switch at all? Are you sure you have the correct firmware to flash through odin?

Yes I am sorry I didn't explained that. Atfer I tried to install stock ROM it got stuck, then smart switch didn't recognize the device but I manage to do the emergency recovery thing with model number and s/n but same thing it got stuck on the same installing system update screen. After that I installed TWRP via Odin to try to push a custom ROM zip, I did that but when I tried to install it failed.

Download Samsung SmartSwitch and from the upper menu select Emergency Recovery Mode, put your phone in Download Mode and connect it to your computer, enter your model number and S/N when asked, and it will download and install latest firmware for your model.
Sorry, i haven't seen that you already tried that.

That means TWRP works and Fastboot/Download works. What is the actual Galaxy S6 model? Mine is G920F.
What custom ROM did you try?
What version of TWRP are you using? The wrong one can create issues.
Did you wipe the phone trough TWRP first? Twice? Including internal memory?

You can't get into recovery or erecovery? Only fastboot? Does it say you still have the bootloader unlocked?

Extract the update.app files with the Huawei Update Extractor program. Google it
And then try to flash the system.img via fastboot in the bootloader

You can't get into recovery right? Or the update menu by pressing volume up + down and power at the same time?

Nah there's still hope. I screwed up worse. I had the same problem that I couldn't get into recovery. But I had the FRP Lock and Bootloader Locked also. But what I had to do was pay 15 Euros for a program called DC Phoenix and it fixed all my problem. Not all is lost

Well you can try to use the SRK toolkit if u want
I need help too, I have a 64 gig US version. Just rooted it today and got TWRP, made a back up. Flashed 2 roms, and none would go past the boot screen so I tried to do my back up and it error'd out at the last minute. I would like to just revert everything back to stock and lock the bootloader. IS this possible? if I do the EMUI update it fails, prob cause the boot loader is locked.

I got it fixed. Had to look for like 20 mins but I'm back! Guess twrp has no AQG5 support. Guess I'm stuck on the AGQ7 for now

If you stuck on boot screen then you have to try to go in recovery mode and flash stock rom.if it doesn't work then you have to flash your device with stock rom.

Galaxy S6 probably softbricked? Ran out of things to try,

I've tried everything that i could find using google. Nothing has worked so far.
My friend has a S6 that was on 5.1.1 with root. It didnt received OTA updates so he tried to flash the new Nougat rom using ODIN. Alas the phone softbricked.
I can access download mode, but doesn't matter what firmware i try ODIN always end up failing. It's either sboot.bin, cm.bin so i think it has something to do with the bootloader? I'm not sure.
Tried to use SmartSwitch too but after it downloads the firmware it gives me an error and says to enter safe mode (????) so that's not working either.
Has anyone have an ideia of what to try next?
Thanks in advance.

Hold down all the buttens on the phone , it should eventually get to download mode , then flash twrp and then flash a rom and see if it boots that way

Already tried. Touchscreen on TWRP is not responsive.
Do you using latest Odin 3.12.7 and newest Samsung USB Drivers and latest right firmware for your model (the best way to get it is SamFirm)?
Softbricked S6, Only Download mode
Hi,
I'm facing the same issue. Tried multiple firmware from sammobile using latest version of odin. I can access only download mode and when not in download it boots till the samsung logo and goes into bootloop. https://imgur.com/a/9bJnM

Touchscreen is not working on TWRP. I'm downloading a Custom ROM and will try to install it trough ADB using TWRP commands. Shot in the dark.
Ended up not working.
Tried PhilZ recovery and I got to flash Global Elite rom but it doesn't boot. Is PhilZ compatible with Nougat roms? What else can I try with this recovery.

Download right newest firmware for your model, use SamFirm to get it. Then use Odin 3.12.7 with newest Samsung USB Drivers to full-flash stock ROM. Set also "Factory Reset" in Odin then START. If Odin shows you 'pass' then everything comes good.

It is OFF. See here => https://imgur.com/a/9bJnM I downloaded the right firmware for model. I'm sure of it now. Used samsung smartswitch to know my csc code using serial number. Still i'm facing the same issue. I'll try flashing it on another pc later today. Also, Should i change any odin setting while flashing ?? Like NAND erase or bootloader update etc

Not necessary, just "Factory Reset" and that's it. I don't know why Odin shows you "pass
" and your phone still shows "system status: custom". Looks like Odin didn't flashing correctly.

This was before i flashed using Odin. I tried flashing twrp first and then stock rom. Does this make any difference ?
P.S: I'm not able to access recovery mode, only ODIN is possible.

Sorry to report but you got hit my the rmm lock again. You will have to wait 7 more days for it to reset again. Sucks I know I've done it myself before. Basically you can't ever even start to boot full stock with oem unlock on and TWRP flashed and without the bypass patch in place or rmm resets and you wind up in 7d flash jail.
A strategy that has been successful so far is to flash twrp leaving auto reboot off and then booting to twrp immediately without even ever loading stock, then first thing before anything else flash the rmm zip. Then you will be safe even if you forget other stuff. Also if you ever flash stock vendor.img again you have to reflash the zip as it changes stuff in there.
Solved
Thanks for your answer.... I Used the Last version of odin modded and flash the last firmware with odin and the phone now is as new jejeje....

What is this Odin modded version? What's the problem with regular Odin?

regular odin can only flash stock firmware for ur model.. modded odin can flash combos or switch between U and U1 firmwares..
modded basically disables hash checks i believe.. u cant flash anything but allows for a bit of flexibility with stock signed firmwares
