Impossible. ALL THE GUIDES? There are so many errors and omissions in THIS guide, it's impossible that you could have successfully completed root by following it. I, too, researched other posts on other guides. Perhaps I missed something. It would be good to clean up THIS guide so others don't have to do it.

Maybe you shouldn't be attempting to root your device if you are incapable of following instructions that every one else seems to manage with just fine.

I suggest you try www.spoonfeeders.com.

Didn't work for me. Tab SM-T380. Using Odin3 v3.11. OEM unlock is checked and running Build RB3. USB debugging is check too if that matters in download mode.

Do I need to flash back to stock firmware first? I don't think I read that I need to flash stock first, just that you said I should download it in case of a soft brick. Or do you think it might be my Odin ver. Honestly I don't know, every time I've done this on previous devises it worked, so not sure where to go from here.

My Tab says "Only official released binaries are allowed to be flashed"

As I was trying to find out what you where talking about. I discovered you where referring to a line of txt in download mode. So I went back to download mode to check. I didn't see the RMM line though. But I thought maybe I have to try to flash again to get that line. But oddly this time it passed. Crazy right? thx for the help tho...

It's amazing that even Samsung's tablets are getting TWRP, even if they might not be as glorious as their phones.

Speaking of which, will TWRP 3.2.0 ever be able to support the older (and weaker) model of this device called an SM-T350? I'm out to build Android Oreo for those old tablets from three years ago and 3.1.1 does not seem to know what an Oreo is.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Chrisrobbins30:
I'm in TWRP but when I try to boot to system I get suck in a boot loop. I think maybe I f**ked up. I forgot to put SU on my SD card and I wanted to do a backup before I booted to system. It wouldn't let me. So I tried wiping and it wouldn't let me do that. So I skipped a step and used the format option. That worked and then I made a backup, but it said something about reloading the data. Then I tried rebooting to system and got the boot loop. I can still get in TWRP but can't get boot system. Do I need to start over? Reflash stock and stuff or am I missing something?

Edit: False alarm again, damn what the hell eveything wants to take 2 tries first. I'm good to go now.

Newbs, if you're having trouble flashing TWRP to your Smasung Galaxy A T380 (2017) and you're having no luck following several different ROOT or TWRP tutorials on here, try a different button combination. I tried over 15 times with existing tutorial combinations (including this one) and they were not right for my device - which is a week old.

Note: after unlocking developer options in Settings, you will have to wait 7 days for OEM unlock to show up in your settings... so turn that and USB Debugging on. But if you boot to download mode in the meantime you may be able to do it anyway on the T380 (thanks to ashyx for pointing this out) - OEM lock was showing as "OFF" the day I got it - I just couldn't get the flash button combos right! If not, then wait the 7 days for the option to show up.

I used ODIN 3.12.5. Uncheck auto-boot (you will find it in the "Options" tab of Odin)

Load up the TWRP file provided in this tutorial in the AP slot.

To put your device into download mode, turn it of, then hold: Power + Volume Down + Home (not what is said in this tutorial)

Flash, then once you get your success message/"PASS" message - here's the important bit that's different from this tutorial and others I've seen. To get out of DL mode, hold Power + Volume Down + HOME (HOME is the additional step that has been missing)

As soon as the screen goes blank, switch to Power + Volume Up + HOME. You should boot straight to TWRP then... and follow the rest of ashyx tutorial for root & installing the encrypt patch.

I don't know why this was different from this tutorial, or others I've seen.... but it was. And I was killing myself using the other button combos with no success (either straight back to ordinary boot following this tutorial steps, or hitting error following suggested Power + Volume Down to ext DL, then Power + Volume Up + Home to boot to recovery in a root tutorial or two).

TL;DR version if hitting problems - use the HOME BUTTON AS WELL on BOTH the suggested steps in the OP's tutorial after flashing.

I've got it to partially work with Magisk by itself.

You have to patch the stock boot.img with magisk manager then flash via odin.

Something doesn't work with it 100% though. Some apps with root work, other's dont.

For example, AdAway works (not systemless hosts though), Titanium Backup doesn't.

I always end up with this notification EVERY time I boot magisk (sceenshot below).

I'm hoping that 8.1.0 source is released for T380, so we can get a working TWRP, otherwise this will be the best we get
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
I think you need to uncheck preserve forced encryption to get rid of that message.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] djb77:
From memory it did the same thing, as I did try several attempts.

I'll try again though to confirm though.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
I have just noticed that the update to 8.1 is downloaded and pending an install. I am still on original stock ROM and don't want to take the update. Will this happen on reboot without my consent?

Are we close to TWRP for 8.1 Oreo?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] djb77:
It does the same thing :(
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Evul1:
Can you be a bit more specific with what you did? My tablet just updated to oreo today. I downloaded the stock firmware from updato, extracted the downloaded zip file, extracted the AP_xxxxx.tar.md5 file, extracted boot.img.lz4 to a boot.img file, patched boot.img with magisk manager, renamed the patched file to boot.img, archived to boot.tar, placed boot.tar in AP slot in Odin 3.13.1, pushed start....and my tablet still gave me the "only official binaries are allowed to be flashed" error.

What did I miss? What did you do differently?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] djb77:
Have you OEM unlocked your tablet?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Cant be rooted on 8.1 theres no TWRP that will work as of yet, everyones still waiting on the source to be released to have a working version for 8.1 unfortunately
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Evul1:
Yes, it was unlocked when the tablet updated to Oreo...

Would you mind answering my question though? Is what I did exactly what you did? Did you use any different steps to install magisk?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] djb77:
No, I did exactly what I explained

Still no responce from OSRC about T380DXU2BRK3, it's starting to feel like they are deliberately not releasing it.

Usually I get a confirmation after at least a few days that they are looking into it (this is the case when I request S7, S8, and S9 Kernel source), but for this particular source they are just ignoring me.

All I can do is just keep on doing what I do every day, and that's keep requesting it every day until they release it.

Today I noticed their e-mail page doesn't work (which is used to request source), maybe they've deliberately broken it so I can't request lol (or its just typical OSRC with bugs)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:

Adoptable Storage

Just wanted to confirm that I managed to apply this method today. Nova Launcher has troubles getting root but other apps don't.

There is that nagging question about applying some environment stuff, no matter which options are enabled/disabled.

To answer some related questions - I've used Heimdall on Linux to flash all images and that worked beautifully.

I'm looking to activate adoptable storage. There are a few options apparently available, whether with Root Essentials or by flashing no-verity-no-encrypt_ashyx (could be the same method?) but these require custom recovery? Anyone managed this part?

I've also flashed this TWRP image but the device wouldn't boot.

Cheers
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Acogu:
As stated in past comments, the current version of TWRP is not working on Oreo. We are waiting for Samsung to release sources so the dev could do his magic. For adoptable storage you need TWRP (AFAIK) therefore I don't think that's possible for now.

You are RMM locked for 7 days. After that OEM_UNLOCK should reappear in development settings.

TWRP isn't currently compatible with Oreo, but when it is you can flash the RMM bypass zip to prevent it happening again.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] nestorl:
I have that option already in developer settings. So i just have to wait anyways? Also, is there anyway to downgrade my tablet so that TWRP is compatible?

Thank you.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
Once you are on Oreo, you cannot go back. There is a physical fuse that gets "burned" when Oreo firmware is installed. If your software (build) number is T380DXU2() then you cannot go back to a T380DXU1() build.

Search this thread for "fuse" for more info.

Hey all, wonder if I can get some help with a T380. I accidentally flashed the TWRP for the 2015 model onto it (followed a link from an xda post in a T380 thread without noticing the difference in model number). Now the device is stuck in a bootloop with the message "set warranty bit: recovery". I cannot turn off the device and the button combinations for download mode doesn't seem to register. Any sort of suggestions or help would be greatly appreciated.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Do you have download mode writing in the top left corner and samsung logo in the background ?

Have you also tried holding power and volume down for roughly 10-20 seconds this force reboots the device

Any download mode will do normal or the one i mentioned as long as you get to that just flash back your stock firmware and it should be sweet
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] qyrus:
I see a split second of "Recovery booting - set warranty bit: recovery" before the device restarts. I've tried everything in regards to turning the device off or entering download mode (vol-, home, power) but I get no response - just a constant loop. I'm waiting for the battery to die and hope that I can enter download mode afterwards.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Generally the button combos work well,

You need to be really really quick when you see the screen go black your fingers need to be faster than light on that download combo, speaking of which what buttons are you using to try and enter download mode ?

On mine & the previous customers i could get to download by holding the home button in the whole time while doing the combo that way only the power & vol down need to be pushed which makes it a bit easier,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] qyrus:
Vol-, home, power. What is your method of entering download mode?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Yep thats the same combo i use and works perfectly,

Try it like this,

Hold the home button in and dont let it go at all even when changing from reset to download,

The 2 main buttons to focus on are the power & vol-

As soon as the screen goes black very very quickly before your tablet even has a chance to boot just hit the power and vol- buttons while you are still keeping the other hand holding in the home button,

I find its easier dealing with 2 buttons and inch apart than having to deal with 3 buttons and the space between the first 2 and the 3rd, less room for error,

What twrp did you flash aswell ? Its very possible the kernel has ruined your hardware, ive done this before by flashing CF auto root for S2 onto an S3 when i first got it years and years ago the kernel litterally burnt my touch controller out so i had a functional screen but no touch,

This kernel may have damaged part of your Emmc of worse hopefully not though and it always pays to read things twice i learnt that the hard way my S3 lasted 2 days from new ive always double checked everything since lol
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] qyrus:
I'll try your button combination and see how that goes. I flashed the 2015 model nougat TWRP, someone posted a link to it in a T380 guide and I didn't pay enough attention to notice it was the T350 twrp. First time I've ever flashed something incorrectly in my android career :\
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
You're not holding the buttons for long enough. Hold POWER + HOME +VOL DOWN until download mode appears.

Whether it's boot looping or not makes no difference whatsoever to the bootloader booting to Download mode.

This is purely pilot error.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] qyrus:
Pilot error indeed, had to hold buttons for a solid minute before download mode popped up. Thank you for your help!

RootExplorer and many other programs work, but Titanium does not work and it does not suit me, I'm waiting TWRP for android 8.1.0
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
There is no solution for the T380, but for the T385, there is a window of opportunity - you can flash T385DDU1ARH1 for the INS & NPL region

Although in the name of the firmware we see 1A, but in it the loader of the 2 series and rollback is possible :)

This is firmware 7.1.1 and the best of 7.1.1 based on usage,

but it is impossible to switch to any 7.1.1 other, since the bootloader in it is 2 versions

Recommendations:

flash part BL & CP from T385DDU1ARH1

the device will reboot and be in Downloading mode again

choose and flash parts AP & CSC

We are waiting for the device to load for 5 minutes, since all data will be reset

P.S. You can save your region, to do this, select a part of CSC from firmware 8.1.0 for your region

Use ODIN version 3.13

Download T385DDU1ARH1: https://updato.com/firmware-archive-select-model?record=AE125207B29111E89F15FA163EE8F90B

registration is not needed and you can download in several threads, which will speed up the download

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
You can not just reset the data,7 days (168 hours) is counted from the last data reset ...

To speed up the process, you need to periodically check for updates and restart the device

Often helps to change the date for 8 days ago and forward, with checking for updates and rebooting the device

And on firmware 8.1.0, I turned on the OEM Unlock and this does not change, no matter how much it was flash to the stock and back with the custom kernel ;)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Shinko02:
I'm still not getting it. I believe restarting the device resets the counter and how does constantly hitting update help? Even if I reflash stock it still won't work. I updated to Oreo 8.1 the first time I booted the tablet. I'm not sure what else to do... :confused:
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
No, the reset does not reset the counter, since this is not the device’s activation time counter in the settings, this is the counter on the Samsung server ...

Even flashing with the HOME_CSC part does not reset the counter, it only resets the data reset and the new connection with the Samsung server.

Either wait 7 days, or try to change the time, check the update (to communicate with the Samsung server) and restart the device ...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Shinko02:
I've changed the time and waited 7 days after unlocking. It automatically checked the update system. It's like it knows how to trick me.
