Bootloop. Help! - Galaxy S6 Q&A, Help & Troubleshooting

Hello. I purchased SM-G920TZKAXAR , Unlocked US version
http://www.samsung.com/us/mobile/cell-phones/SM-G920TZKAXAR
Then I tried to root it by following this guide: http://joyofandroid.com/root-samsung-galaxy-s6/ and using Method 2 via TWRP and then flashing cf-autoroute from https://autoroot.chainfire.eu/ . I downloaded zerofltetmo LRX22G.G920TUVU1AOC9 for SM-G920T.
my process:
1. Copied CF-Auto-Root-zerofltetmo-zerofltetmo-smg920t onto phone
2. entered Downloading mode and then connected Odin
3. PHone rebooted into TWRP and then I proceeded to flash CF-Auto-Root-zerofltetmo-zerofltetmo-smg920t.
As a result I get bootloop.
I tried downloading stock T-mobile firmware and flashing to via ODIN but it FAILED in Odin/Download mode due to SW rev check not validating. I tried to use different version of TWRP, 2.8.7.2 , 2.8.7.1 and 2.8.7.0 but bootloop continues
What can do I to fix this? I don't know what else I can try and I can't locate a stock firmware for SM-G920TZKAXAR if such exist.
Thanks!

[Q] Stuck in Download Mode

Hey everyone I'm quite new to android, and I'm currently stuck in Download Mode after trying and failing to install Twrp 2.7
I was previously rooted, tried to install Twrp via Autorec, however when I ran the app it soft-bricked my phone and put me into Fastboot mode.
I followed http://forum.xda-developers.com/showthread.php?t=2476972 method, and got back to Download Mode.
I am currently in the middle of returning to stock through http://forum.xda-developers.com/showthread.php?t=2432476 using the .TOT method.
I'm fairly close to repairing it but my only issue is that I cannot get my computer to recognize my phone. Neither in Device management nor adb devices anymore.
Therefore I cannot change the port to COM 41 to flash the .TOT file.
I constantly tried installing drivers for the phone both 3.10 and 3.08 but still no recognition can anybody help?
Some more info about the phone:
it's the D801 variant but its on Wind (Canada) not T-mobile
it was previously rooted
it did not have any recovery software installed
no roms had been flashed previously.

flashing supersu puts note with lolipop into boot loop. cant figure out how to root

I have tried a few different methods to root this. I recently upgraded the firmware with samsung's official lolipop download via odin. works fine. installed twrp via odin, works fine. but when i try to root it sends it into a boot loop.

Bricked Phone - rooted and then flashed TWRP

So basically I managed to brick my new S6. I rooted it by flashing the unibase with odin. The phone booted correctly and everything was fine. I then decided I needed a custom recovery. I used the application Flashify to flash the recovery. When the phone rebooted, it was stuck on the Samsung logo, with a red message at the stop saying "recovery is not seandroid". What do I do? I'm guessing I need to flash new files using odin but I don't know which - I'm on android 5.1.1 and my model number is SM-G920F. Any help would be appreciated.
In Odin install the .tar (or .tar.md5) files provided with TWRP (https://dl.twrp.me/zeroflte/twrp-2.8.7.2-zeroflte.img.tar.html) or PhilZ Touch Recovery (http://www.arter97.com/browse/exynos7420/recovery/11.0/g920fi/) made by arter97.
It is possible that installing TWRP again using Odin can cause the S6 going into another bootloop. My solution for that is to flash a kernel (like arter97's one or Adam Kernel) and then the phone should boot just fine.
Edit: If you will flash a custom kernel you will not need to root the phone again because these contain SuperSU and maybe Busybox.

Samsung has download mode, not bootloader mode(kinda the same but not exactly because download mode is not fastboot compatible but devices with bootloader mode are fastboot compatible).
As for the issues you're having, try this thread for troubleshooting a failed Odin flash.

tried all the usb sockets on my computer, noting changed
When i try to power up the phone it says: " Firmware update encountered an issue. Please select recovery mode in Kies & try again."
Install TWRP Recovery in your Note 4 I had also this issue early. First Root your device then install twrp recovery and download Tedy Bear Rom Android 6 Marshmallow easily Available on this thread https://forum.xda-developers.com/t/...10c-h-tedybear-rom-v1-5-updated-v1-5.3768967/
