Galaxy Tab S2 T819 "Verification failed" AND bootloop - Galaxy Tab S2 Q&A, Help & Troubleshooting

EDIT
OK, I've found the Home + Vol Down + Power, then slide from Vol Dn to Vol Up trick. This takes me into TWRP proper, and I've done a Factory Reset. All is now well, except I'm still bloated.
**********************************************************
I've installed TWRP 3.2.3-0 (eventually) and now I've got the famous "Verification failed" problem.
When I press "RESET" it boots into TWRP and runs an OpenRecoveryScript (bloody quickly) and then reboots to the "Verification error" screen.
***
I've got a TWRP backup, and there's no data on there anyway.
I'm on Linux so I've used Heimdall to flash TWRP.
***
Vol down & Power takes me to the "Verification failed" screen. Home, Vol down & Power does the same.
Any ideas how to progress? I only want to debloat the effin' thing.
TIA

After flashing TWRP in download mode, go straight to TWRP recovery, just unselect odin option autoreboot. The system might try to recover the original recovery. From TWRP recovery, flash custom ROM.
That's as far as I remembered, I owned tab S2 but not as main tablet any more.

No Command

I have unlocked the phone successfully and flashed the TWRP 2.7.1.1 image with partition mismatch error. However when I go into recovery, I get the NO COMMAND screen
Tried pressing the power and volume up, but no success.
Thanks
Update, pressing vol up for few seconds and pressing pwr btn once opens the recovery menu. But it is not the typical TWRP touch interface.
Superuser is not installing
It goes up to verifying zip and then Installation aborted message.
Any help on installing superuser will be appreciated.
Thanks

Problems installing TWRP in Tab S2 T713

My Tab S2 T713 is currently running the latest stock Samsung rom. I want to install Lineage 15.1
I've downloaded twrp-3.2.1-0-gts28vewifi.img.tar & Odin 3.12.7. I can boot into download mode, flash TWRP with Odin which says success & my tablet reboots normally. When I power down & reboot into recovery TWRP gets over written by the stock recovery.
If I uncheck Auto Reboot in Odin, after flashing success, I'm still in download mode - I've read that I need to boot directly into recovery from download mode - how do I do this?
In download mode pressing home + voldown + power reboots normally. Pressing home + volup + power does nothing
What am I doing wrong?

Instructions:
Flash with ODIN 3.10.7 in the AP slot.
Put your device in DOWNLOAD mode.
Uncheck Auto reboot.
Load the respective file below into the AP slot and hit start.
After flashing and ODIN reports PASS immediately reboot to recovery by holding POWER + HOME + VOL DOWN.
As soon as the screen goes blank change to VOL UP whilst still holding POWER + HOME.
You should now see TWRP recovery.
Brilliant - thank you. Why they can't have they have that in the Lineage install instructions?
Now running Lineage 15.1 = happy bunny

For the love of god, thank you. This wasn't in the LineageOS instructions. But I still can't install it, it says my bootloader isn't supported (T713XXU1APG1).

Did you go into your developer settings and make sure you toggled the option titled "OEM Unlock"?

Good to hear! Please make sure you give a thumbs up to anyone who helped. It really keeps the community alive and kicking!
I found that I had to do this from completely powered off state:
press home + volume up + power
wait until second "sentence" appears on screen in yellow (the first "sentence" is blue),
Then release all buttons
twrp now boots.
for some reason, my internal and external storage is showing 0 mb. Anyway to fix this?
Try formatting (not just wipe) data.
Should the Galaxy Tab S2 2016 be on TWRP 3.2.1.0 or the new 3.2.3.0 for Linage OS 15?
If so, can't you just flash the update using TWRP on the img file, or is ODIN on the tar needed?
OK, I updated to TWRP 3.2.3 using TWRP Recovery and the img file. Appears to work fine.

Sorry to revisit this issue. I can't get TWRP going on my S2 Tablet. I understand these instructions, but at the end of the ODIN installation there are two possibilities that I can see. If you set the ODIN to automatically reboot then you cannot do the above because it says to do it from completely powered off.
If you don't set ODIN to reboot automatically I can't get the tablet to turn off. I can only get it to boot by holding home+volume down + power. How do I get the tablet to power off before booting??
I am using ODIN 3.14.4 and TWRP-3.7.0 9-0-gts28wifi.img.tar and my stock firmware is NRD90M.T713XXS2BSG1 with Kernel 3.10.84-14953299
Thank you.

Cannot flash/enter twrp.

Hi.
Im having alot of trouble doing custom stuff with my mi 9. At this point i have succesfully flashed aospextended on my mi 9 but i cannot enter twrp. It just "recovery loops" with the mi logo. I have tried flashing it again, just booting to twrp from fastboot but it still won't boot to twrp. I am consistently having issues booting to twrp at a point where i had to flash global stable from fastboot because it never stopped booting to stock recovery, where after i formattet cache and userdata. Thanks in advance.

Hi!
Try telling us what you have done so far (in terms of modifications as well). Which recovery did you (try) flashing?
I personally tried skiantibag & maufirinio (I know it's not the proper spelling but you'll find it) + flashing RevolutionOS.
You've probably heard it already: Fastboot -> flash recovery -> does it boot into (after shutting down -> volume up + standby pressed)
If not try (first flashing the recovery) then booting from the .img file via fastboot.
After that wipe everything and flash Revolution OS/xiaomi.eu. Do you still experience the problems then? Short hint at the end: setup a password (code - during the android setup process) since your storage gets encrypted (no matter what - at least for me).
Good night, good luck!

after flashing twrp, (assuming ur using fastboot cmds to boot to twrp) use buttons to reboot to twrp. Long press power button and volume up together until device reboots, once it vibrates, let go of power but keep holding vol up until twrp boots. Then disconnect phone from pc. Twrp should now stick. Which twrp you using?

This. Rebooting from command line did not work for me either. Just press power + vol up until screen closes and keep pressing 3 more seconds after mi logo appears.

Question Flashed custom rom, phone reboots into twrp and now i'm stuck

Flashed my Note 11 which was on Android 11 by twrp 3.6.1. When the install was done i rebooted and the phone reboots into twrp. What can i do next?
Edit: it now only boots into fastboot, regardless if i only press just the power button or the power button + volume down.
New attempts: the custom rom zip file on the phone is disappeared so i have to use ADB sideload to flash the rom by the pc. When the process is done i get the following error, see picture.
Did "format data" in twrp and it boots now normally.

Sm-G935W8: Can't install TWRP and root?

Greetings
Thanks in advance
I tried following this video to install TWRP and root:
I used ODIN as they suggested and it says it completed the flash.
I followed directions and tried to get into TWRP but it shows "no command" after "installing system updates" after holding down power up + power + home button
I can sometimes get into the menu where it asks to wipe cache etc but it does not go into TWRP and gives error saying it can't find something. I assume this is because of TWRP not loading?
Any idea how to get this flashed with TWRP?
Here are screen shots from the recovery mode I got into.
Looks like it can't find thew TWRP?
Looks like this issue?
now when I turn the phone on it goes into "installing system update" and goes to blue screen with "no command" dead android icon.
it used to boot into the OS but now it does not? It's like bricked now?
I went back into recovery and reset factory image and it boots back into the OS now.. so its not bricke.d.
But still it wont do the above and install TWRP
