How to install TWRP on SM-G920T with Marshmallow 6.0.1? - T-Mobile Samsung Galaxy S6

I softbricked my phone trying to install bootloader/modem for XtreStoLite ROM and I never completed the process. Only fix was to do Emergency Recovery with Samsung SmartSwitch, which I did. Now I have 100% stock 6.0.1 and stock recovery.
Next I tried to install TWRP via Odin. Now the phone boots normally, but I can't boot into recovery. When I try to boot into recovery, it says "Recovery is not SEANDROID enforcing" and it's stuck in boot. What is the method to successfully install TWRP on 6.0.1?
Thanks

Lost TWRP and root after installing rom

Hey everyone
I've been using the XT1053 Retail US Stock Lollipop Flashable ZIP without issue for quite a while, but decided to update to the modded version 2. So I flashed it, xposed, and supersu again. Booted up, everything was okay. But then it said I needed to update my supersu binary and that I didn't have root, so I went to reboot into recovery and flash supersu once more.
However, now I can't access TWRP and it merely says "no command"
Should I just try installing TWRP again or is there a way to see if it's still installed? It's weird that this happened after flashing a rom
edit: reflashed twrp recovery img, back to normal. Can't explain what caused this though

s3 mini with a twrp 2.8 that hangs

I had cm12.1 on it and only wanted to clear settings in android.
It had to reboot and stuck at twrp begin screen that keeps flashing.
Only odin works now and tried installing another twrp and cwm too, all succesfull but still that twrp boot logo flashing even when cwm installed.
Normally i can manage but have no idea now. If recovery worked it was fine but just thru odin seems that twrp is write potected almost.
Any clues someone
rebooted manually also, uncheckedauto reboot box after flashing twrp new rom
nothing, still stuck

Unable to flash TWRP after with OOS 4.0.2

I flashed TWRP with succes according to cmd. But when booting to recovery it gives me the stock recovery. I had the same problem with my OPX. Someone on here said that MM had a new bootloader so i had a TWRP that was compatible with that bootloader. Is this the same for OP3T? If so can anyone link this

Click to expand...
Click to collapse
flash twrp 3.0.4.0 (in OP3 forums, now unified), from fastboot boot immediately to recovery it should boot TWRP, flash SuperSU or similar (or kernel that will rename stock recovery) to keep TWRP, reboot recovery from TWRP to check it works, reboot to system and profit.
if you don't root, stock recovery will keep coming back.

Install twrp with flashtool?

Hello, is it possible to install twrp permanently via flashtool?
I flashed twrp img with flashtool (select kernel to flash) but then my phone wasnt able to boot up, so I installed lineage os rom.
After that, I booted up to system without any problem. I restarted my phone to check the twrp recovery but I noticed that It reverted into the stock one.
I tried to install twrp via the twrp app, the app says it flashed successfully but when I boot up into recovery, my phone shows the stock one. Please help me someone.
nevermind, I managed to install twrp with rom toolbox app.
