Thank!

see line 7 above

RMM STATUS: Prenormal

and this state and prohibits the firmware of any unofficial file.

on firmware 7.1.1 this line is removed after waiting 7 days (168 hours), on firmware 8.1.0 this option is disabled (not active) and cannot be deleted

It is impossible to return to firmware 7.1.1, since the bootloader does not allow downgrades :) .

You were inattentive and updated the firmware to 8.1.0 from 7.1.1, where there was already a state

RMM Status: Prenormal and there is no way back ...

P.S. there is a possibility to roll back to 7.1.1 on OS Linux using Heimdall, but there is no personal experience

question,

What will disabling the forced encryption do? is it optional in installing Magisk onto the device?

Also what will the RMM bypass do?

---------- Post added at 02:04 AM ---------- Previous post was at 01:18 AM ----------

My sm t380 failed to flash twrp,

I looked at my device and it displayed "

Only official released binaries are allowed to be flashed.

And I don't know what to do from here.

I turned on oem unlocking and usb debugging, I used odin3 3.13.1 and tried it in odin3 3.12.5.

it would be appreciated for anyhelp
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Specify - the device T380, and what firmware, which version of android 7.1.1 or 8.1.0?

If the firmware is 8.1.0, then the answer was written on the previous page and the problem in RMM Status: Prenormal

Concerning questions:

The answer depends on the firmware version of the android:

7.1.1 doesn't need decryption patch, Magisk will do it

and on the contrary, the RMM patch is needed, since otherwise after the first reboot, the device will be blocked with a message - Only official firmware

On firmware 8.1.0, it is necessary to apply the decryption memory patch, since Magisk will not do this and at the first reboot it will be denied access to the memory with the request to reset the data.

RMM patch is not needed, since this feature is disabled on 8.1.0 and the string

RMM Status will never appear, but if the line is moved from 7.1.1, then it cannot be removed ...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] CaptainChris2018:
Is there a possibility to remove the RRM Prenormal lock, maybe with adb or something like that and i am on 8.1.0

P.S. i updated to 8.1.0 back in December, why is there a oreo twrp for the t380 then if there is the RRM lock

I also have a Rooted Android 5.1 Device, by the way.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Using adb RMM Prenormal lock is not removed, since this is the bootloader option and is turned on and off remotely from the Samsung server.

This could be done on firmware 7.1.1, but it will not return to it from 8.1.0, for the T380 model there is no rollback :(
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Acogu:
Hey guys, any of those who are now rooted on the T380 (oreo), could you tell me if Adoptable Storage can be enabled. It used to work on 7.1 but on Oreo I couldn't. Its been a while since the last time I tried to root the tablet and to enable Adoptable Storage with no success.

Let me know if any of you have Adoptable Storage enabled on Oreo, please.

Thanks!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
On firmware 8.1.0 Oreo Root-rights are incomplete and therefore does not work Titanium and some other programs :(

The problem is in the core of Oreo, and the patch from Magisk does not completely disable the protection (defex) and do not get full access ...

The T380 models are lucky, since there is a patched kernel in the subject, with which Root-rights should be complete:

Most likely there are Root-rights, but incomplete, I wrote about this above ...

thank you for your reply talich52. i redid everything and this time after flashing the rmm, i installed the defex patch image. i rebooted and im stuck in boot loop. any ideas? i havent rooted anything in a long time so im a bit slow lol.....update....im pretty sure its bricked....it wont even boot now. i might be able to unbrick if i had the original firmware but i cant download it from anywhere. its saying no operating sytem
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
press 2 buttons and hold them as soon as the display goes off,press 3 buttons to enter Recovery or Downloading mode.

Flash TWRP and install Magisk from it.zip,which will disable protection and the device will be able to boot.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hughGee:
hey thank you. i did what you said and it says "no operating system" when i go to reboot. when it does reboot, it goes directly into twrp recovery again
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
If the system fails to start,the device goes into recovery mode,i.e. into stock recovery or TWRP.I recommend to download and flash the stock firmware,which has now been installed...

Free and fast enough you can download the firmware for T380 from here: https://samfrew.com/ru/model/SM-T380/

P.S.Perhaps the problem is not in the system,but in the kernel,

the boot.img you flashed,but it doesn't match the model of the device or the Android version.

If you specify which firmware is installed,I can upload the stock kernel for firmware via ODIN or TWRP
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hughGee:
Thanks Talich52, i have twrp recovery but like i said it says no operating system at all times....ive tried to DL the stock firmware and it either doesnt Dl at all or its corrupt. ill try samfrew again but if you could postit , i would greatly appreciate it. i also made sure the firmware i used was the one the OP posted for oreo. Again thank you for all your patience and help. P.S. when i navigate into internal storage, the only file in there is twrp
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
this indicates that the memory is encrypted.To access the memory need to perform a format data (not wipe data) from a TWRP and apply the patch to disable encryption follow-up... this patch I posted earlier in my message.patch here: https://xdaforums.com/attachment.php?attachmentid=4682858&d=1547011951

You still haven't told me what firmware is needed. Model SM-T380 ,firmware 8.1.0 Oreo ,and the region?or country?

The firmware must be installed with the part CSC=CSC_,that is, with data reset,this will clear the memory,but restore the system...

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] hughGee:
ok, its done again.........back at square one. rooted but checked with root checker and it says not rooted. im supposed to flash the defex file which should give me complete root rights right? and if i get stuck in boot loop again....re do everything?

Hey - I just wanted to leave this here incase it helps someone else who might bstuck where I was

I also updated my T385 to oreo and ended up with prenormal RMM and unable to flash TWRP.

I was able to fix this using miracle box. I followed the instructions linked below to 15. But at 16 I returned to flashing TWRP with this thread here

Got error with TWRP for Oreo T380 after updated to Oreo

Cannot access memory card (invalid parameter) but USB OTG is OK
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] BluesElwoo:
Rooted with problems

So I followed the instructions. I then got the partial root after flashing magisk 18 and rmm bypass. Titanium backup won't work at this point. Then flashing the defex file (https://xdaforums.com/showpost.php?p=78600215&postcount=279) makes your device boot loop. Then reinstalling magisk 18 in TWRP brings the device to a point where Titanium backup works fully! Installing Magisk 18 rather than 19 is important to get this to work (https://xdaforums.com/showpost.php?p=78774974&postcount=373).

2 Biggest problems I am having is that the screen has some extremely distorted colors if you let the screen lock. If you restart the device, colors go back to normal. Also, as ashyx said when telling us that we need to flash the defex file, the MTP won't work, which is something that I need for what I was going to do with my rooted android.

When progress on rooting the sm-t380 gets to a point where the root on oreo is stable, I will more than likely donate to ashyx, but until then, im not sure its worth trying to root your sm-380 with oreo installed. I bought my sm-380 less than a week ago with the intention on rooting so I can display my full android screen in my truck on the head unit, because Android Auto by itself sucks. My sm-t380 came with oreo already installed on it. I may look into dropping down to nougat so I can get a full stable root. Im sure someone would be able to tell me why oreo is better, but for my purposes, im sure nougat is just fine.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] BluesElwoo:
I actually just got to the same point I was at before by installing the defex file and then installing magisk 19.1. Same crazy colors after the screen locks and no MTP as was warned. I just wanted to correct what I said last that you needed v18, 19.1 is the same.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Yes, the current version of TWRP for firmware 8.1.0 Oreo does not work with the exFat format :(

Solved the issue using a flash card via OTG adapter, flash card in Fat format (Fat32)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] mingkee:
I have a 32GB memory card somewhere.

I will use the card instead of 128GB one
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Yes, this is also a decision :)

Cards up to 32GB are formatted by the device in Fat and will work with TWRP,

But it is more convenient to connect an OTG adapter with a flash card than to change the standard SdCard, especially if the device is wearing a case ...

Odin says passed and I know how to boot into twrp recovery however I either get stuck in download mode or back into stock recovery.... Is this a problem for anyone else or just me

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
First, in ODIN, disable the AutoReboot option,

After uploading the TWRP file, unplug the cable and hold down the 2 Volume Down and Power buttons.

Hold the buttons until the display goes out, then immediately hold down the 2 buttons Home and Volume Up.

After appearing at the top of the inscription Set Warranty Bit: recovery, you can release the buttons :)

P.S. If the device restarts after uploading the TWRP file, then the stock recovery is restored ...

anything on when this root method will be more stable. "Busybox" or "Busybox Pro" will not install after properly rooting with this method on my device. I get an error saying busybox wouldn't install because it could not verify the integrity of the binaries, give or take a few words but the jest is there. I found the system binaries in the \vendor\bin folder and it appears they are simlinked from another directory by Samsung. I think this is causing the issue with busybox. With the 7.1.1 root method, which I should have stuck with, Hulu worked fine, magisk had no trouble hiding root access. I'm currently using the latest oreo rom from Samsung, T380DXU3BSD1. Every time I root the device I end up with these issues plus some performance issues. the unit just seems slower after being rooted. Shame Samsung has to be a bunch of jerks and wad up the works to try keep us out of OS and not let us flash back to 7.1.1. either. which I would really rather do if possible but supposedly not. Any ideas or anyone else having similar issues they've gotten worked out. I've tried everything I know. I'm no developer but I do have a fair amount of experience rooting android and something is definitely not clicking for me. Thanks in advance guys and gals.
