Unable to get over RMM: Prenormal issue and flash TWRP - SM-T385 Oreo (8.1.0) - Samsung Galaxy Tab A series Questions & Answers

I've been searching for a way to root my Samsung Galaxy Tab A ( 8.0" 4G) SM-T385 for about a week and a half now. Everything I've tried has failed (list below), I've searched and searched on these forums but can't find a successful method. When I try to flash to TWRP I get the "Only official released binaries are allowed to be flashed", I've tried to remove the RMM state but also unsuccessful. The annoying thing is i can't get past this first hurdle so who knows what other problems I might encounter :S
The error I'm getting:

Tablet Specs:
Galaxy Tab A ( 8.0" 4G)
Model: SM-T385
Version: Oreo (8.1.0) T385DXU3BSD1
My Goal: To Flash TWRP, then install Magisk to root my tablet.
What I've tried (not an exhaustive list but you get the idea):
- Flashing TWRP:

- Bypassing RMM state Prenormal
https://forum.xda-developers.com/galaxy-s8/how-to/how-to-bypass-rmm-prenormal-to-install-t3891193
- I've tried flashing official binary to try and reset RMM state. I was able to sucessfully flash but it did not remove the RMM state Prenormal
- Using third-party apps to root device like Kingoroot
Any help would be very appreciated!

no problem
I have the same device and had no problems flashing twrp with Odin.
It sounds like, from lack of information that you have not unlocked the boot-loader.
If you need help with this step, let me know by replying to this post.

Trouble with booting after rooting, help.

Hello everyone, I went to root my phone today, I used a Youtube tutorial with the exact links/downloads given. Followed the steps but my device is having trouble rebooting, it is just stuck on the Samsung logo flashing and I'm not too sure what to do. Also when it boots up I get the error message in the top left of my screen saying "Recovery Is Not Seandroid Enforcing", hopefully that helps.
Thanks.

Hard to help if you do not write in detail. Such as phone type, links you have used, etc etc

You need to flash SuperSU manually.
1. Flash TWRP
2. Format data
3. Flash SR3-SuperSU-v2.79-SR3-20170114223742.zip
http://download.chainfire.eu/1021/SuperSU/SR3-SuperSU-v2.79-SR3-20170114223742.zip
You simply brick your phone. You need to know that there is not Chainfire-AUTO-Root for Nougat, so you need first flash Stock FIRMWARE from Sammobile, then flash TWRP and flash SuperSU
Or you can flash many of 100 roms with prerooted supersu and busybox.
Hi there,
After upgrading my S7 Edge G935F to stock version xxu1dqd7 (with latest May 2017 upgrades) I had to install TWRP (twrp-3.1.1-0-hero2lte.img) again.
Unfortunately this change will NOT recognise my pattern lock now! I had to re-install the stock image (DBT-G935FXXU1DQEF-20170523093738 with ODIN) using the HOME_CSC file to hold my data.
This re-installation brought me back to the game, but without TWRP and hope for root, but the pattern pin (the same) is now working...
Update 1
Installing TWRP (twrp-3.1.1-0-hero2lte.img) over the new stock image (DBT-G935FXXU1DQEF-20170523093738 with ODIN) without having the pattern lock enabled feature during start will result in stuck on
the samsung title.
Update 2
I had to repeat the step above (stock firmware), so stay now without root.
Will check later with other stock versions
>It seems you didn't format the data partition or dm-verity was not installed. Happened to me, won't boot if >anything is altered like when installing a custom recovery.
Yes, I did it with and without dm-verity, All 3 options,
TWRP (ok, but pattern lock will not recognized)
TWRP + supersu (2.82) (stuck on the samsung logo)
TWRP + supersu (2.82) + dm-verity (stuck on the samsung logo)
Yes, I didn'T format the data partition. Didn't want to lose my data ( Never had a problem to upgrade stock roms on my old S4 and root after).
Before the stock upgrade, I run with the Jan 2017 patch level (I bought this 2 days ago) and was able to root with the above method.
Today I wanted to jump the the latest stock version but run in trouble then.
Update 3
Downgrading to Stockrom from 2017-Jan-30 Germany 7 G935FXXU1DQB3 G935FDBT1DQA8 is not an option (anymore), The system boot up but with lot of errors and it's unresponsable and not usable.
Upgade then to the April patch status (2017-Apr-17 Germany 7 G935FXXU1DQD7 G935FDBT1DQD1) brought me back to operational,
but TWRP + supersu (2.82) + dm-verity (stuck on the samsung logo).
Will try it now with the Februar patch version
Downgrade to the Feb patch status (2017-Feb-23 Germany 7 G935FXXU1DQBX G935FOXJ1DQB2) had the same resut like the Jan version - not usable.
I'll give up now and install the April version without TWRP.
I need root to restore my apps AND data with Titanium Pro.

With the TWRP + supersu root method, no matter what 7.0 stock ROM you use, you will not succeed before you disable boot pin and format data. You can restore data after rooting.
So start with the latest stock ROM that is working 100% for you, flash twrp, format data, flash supersu, and it should work. You have to format data because root and stock rom currently does not work with encryption.
Or even simpler, use the new cf autoroot, however it seems you still have to format data.
I had high hopes that the new cf autoroot nougat binary would work with encryption, but alas it seems it doesnt, at least I had the same wrong pin code at boot issue as with twrp. I havent had time to test it, nor to format data and root, so I am currently not rooted.

Thank you doclorenzo.
I had success with the latest stock version (xxu1dqd7) and your recomendation to format data in TWRP.
In short: Boot in Download mode, Install TWRP via Odin, Boot into TWRP - format data, supersu (2.82) + dm-verity
and then restore all data. Unfortunately it requires lot of time (at least 4 hrs to restore the apps + more for fine tuning)
Thank you and hope to have a better way with the next stock update and TWRP

HELP only official released binaries are allowed to be flashed

Hi guys today i tried to root my device with twrp and magisk. After flashed magisk from twrp, it said i should format the phone and i did. Then the problem happened. I tried flash stock rom from odin but it failed every time. How can i solve this problem?
device G950FD
when rooting, oem setting was on.
Help error samsung (only official released binaries are allowed to be flashed)
help me, I wanted to root on my j5 prime SM-G570M phone and first was giving trouble to install twrp (remembering that the device is under warranty) until I finally succeeded. I put the zip file to do the ROOT and it worked. When I rebooted the device appeared a message saying that the android system could have been violated, had to restart. When I rebooted the device gave this error (only official released binaries are allowed to be flashed). He calls and does not leave this text in red.
Please help me, I'm desperate. I searched a lot and did not find the answer. I only read answers that maybe I have to wait 7 days. But I'm not sure

How to relock the Bootloader on G950F Exynos without TWRP and without root access?

Days ago, I had the wonderful idea of installing TWRP. I didn't want to install a custom ROM, I simply wanted TWRP + the current android. However, after I installed TWRP, the Android 8.0 was wiped out. I thought I would still keep the Android 8...
I tried to install many older versions (from April, June, July, August) of the stock ROM 8.0 via Odin, but all of them failed (as far as I learned, they failed because they had an older version than the Bootloader I had installed), then I successfully installed a stock ROM build from December.
Now, my phone doesn't pass the SafetyNet Test. It fails on "CTS profile match" (I read on the internet it is due to the unlocked Bootloader).
Interesting thing is: when I browse to "Developer Options -> OEM unlock", it says "Bootloader is already unlocked", even if the option is unset.
Now I have no TWRP (and I don't want to play with it anymore) and I have no root access.
Does anyone know how to "relock" the Bootloader or do anything that will allow me to pass the SafetyNet Test?

SM-T380 Stock Image Files

I just upgraded to Pie on my SM-T380 and am now running into an issue after trying to re-root the tab.
I had previously rooted the tab using TWRP and Magisk and didn't have any problems except that I could not update Magisk since every time I went to TWRP I could not mount data, etc. I did an upgrade from Oreo to Pie today and it appeared to work without problems. I then tried re-rooting following the instructions here SM-T380 Rooting Guide but now only get an error screen when booting up (Security Error...) stating that "Only official released binaries are allowed." I can't boot into recovery and I've tried to reflash TWRP and get a FAIL in Odin every time.
I've tried to find the stock images to just reflash everything through Odin but am unsure which is the right image file (https://www.sammobile.com/samsung/galaxy-tab-a-2017/firmware/#SM-T380, I'm in the US). Can someone point me in the right direction?
Appreciate any help!
I found firmware for my T280 at this website https://samfrew.com/
