[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Unimaginative:
I was able to install 9.0 with this TWRP without issue after making a flashable .zip from the Samsung OTA package using ClassyKitchen and it seemed fine. Unfortunately - as Talich52 pointed out - there's no root method at present, which kind of remove the point of a customer recovery so just flashed 9.0 from Odin to 're-stock.'
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] turboperson123:
are you going to be making a twrp recovery for android 9
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Twrp already works on Android 9.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] turboperson123:
the developer said that it would work on android 9, but when i flashed the encryption files its still bootlooping
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
You installed custom TWRP recovery, but now kernel protection will not let you boot the system :(

You need to install Magisk.zip of any version, Magisk will not work, but the kernel will be patched and protection disabled, after which the device will boot :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] CaptainChris2018:
When I get a chance, I will try flashing the oreo twrp to my t380 devices running pie.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] BethanyJane:
Is this as well as, or instead of the patch you said I would need? ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
after installing TWRP, you need to do:

1) format data

2)install

Tab_A_2017_Pie_forced + encryption_disabler_test.zip to disable memory encryption

3) install Magisk.zip to disable bootloop

4) select and execute Reboot system now
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] BethanyJane:
Thanks so much for your help... I'm still a little nervous though cos I've bricked a few in my time lol. I guess I'm also windering is there much point in flashing twrp if there is no root available, I mean it's a great recovery but without root can it still be useful?

:confused:
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Unfortunately, no version of Magisk.zip does not grant Root rights,as it does not disable protection in the kernel.

However, TWRP works and its built-in file Manager works. You can delete unnecessary applications, add your own to the system,I added my fonts, which otherwise do not work... I hope to get a kernel with disabled protection and set Root-rights :)

I'll try and sort something out this weekend. Unfortunately I've had a rubbish few weeks due to my mother in law suddenly passing away.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] CaptainChris2018:
Hello, I got TWRP running on my t380, I can't find any ROMs for it, but why?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Unimaginative:
My condolences mate. Cheers for all your efforts.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] CaptainChris2018:
Hey, installed TWRP on my T380 on Android 9.0, and I did a factory reset and installed masigk mupitle times, and it's not working. Does anyone have a fix?

That's Sad, I'm sorry.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Austcool:
I have taken the liberty of going to Samsungs opensource site and requesting the android Pie kernel source codes this will allow us to see what they have changed in the kernel code that is preventing magisk. What we should also attempt to do is figure out with a hex editor what hex code patches are needed to disable Defex in the SM-T380 and SM-T385 considering the ones in magisk are not working do to the patches being used to patch it are SOC specific.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
I already did that a week ago. Samsung take around 10 to 12 days usually.

We don't need hex patches with the kernel source.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Austcool:
I know but there long dragged out wait time is driving me nuts.

I just figured hex patching in the future if it remains the same could be just a easy edit to magisk scripts for patching the kernel so we don't always have to wait 10 or 12 days
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
The problem with hex patching is that it can quickly become defunct and for something like Magisk the patch has to be generic.

As you've noticed Samsung are continually modifying the source which breaks patching.

It's a game I've been playing with Samsung for quite a while and it becomes quite tedious.

We fix, they break, we fix again, they break again and it goes on like that continuously.

Besides there are more protection mechanisms that need to be disabled than just defex for things to work correctly.

SELinux, dm-verity, five, proca, defex to name a few.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
I have compiled the kernel below from alternative Pie sources. It's a bit of a hack job, but may boot.

Install with TWRP as an image.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Austcool:
where did you get that code could I please play with it?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Thank you!

It’s a pity that the kernel is for the T380 model, but I have T385, but I tried to install it, the kernel was installed, but the device does not start - bootloop ... I applied Magisk.zip, but it didn’t change anything ...

Earlier, when installing the kernel from a Wi-Fi model to LTE, the mobile network simply did not work, and now the device does not even start ...

I'll wait for the kernel for T385

P.S. By the way, an update was released for Taiwan - T385DXU3CSJ1, the kernel has become a bit larger, I will attach it in a zip archive
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Austcool:
well that kernel booted directly into download mode for me didn't even bootloop just went directly into download mode with the black and white galaxy tab A screen...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Ah well it was worth a try.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
It's the MSM8917 Pie source for the J4.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Austcool:
have you heard anything from samsung?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
This is built from the T380 pie source. If it boots I will compile for the T385 also. It will need patching by Magisk after install as I haven't disabled dm-verity.

https://androidfilehost.com/?fid=4349826312261626422
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Thank!

I installed the kernel on T385, the installation passes, but the device immediately enters the ODIN mode with the inscription ... fdt

Installing Magisk.zip doesn't change anything ...

We are waiting for the verification of the file from the owners of T380

and kernel for T385
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Not sure I quite understand? Can you show a screen shot of what you see?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Can you try this build repacked for T385?

http://s000.tinyupload.com/index.php?file_id=01994417388159785800
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Thank you very much! Everything worked and even Titanium.

Updated Magisk! at the same time, the update is installed in the recommended direct way, that is, from Magisk itself

:)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Good to hear, just need someone to confirm the T380 build and we're on to a winner.

Could you confirm you are able to set a lockscreen password?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
Here is the confirmation in pictures.

Installed and works, although I do not use it...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Thanks for confirming.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Red117:
May i ask, does the modified boot for the t385 break ota, i have a telstra (au) model and it still recieves occasional updates? I know it's a symptom of rooting that ota gets broken, i was just wondering since magisk is being used
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Any customisation will break OTA's.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Red117:
I figured it would, i just know there is a method with magisk that allows ota (if you patch it correctly), i think that only works with A/B boots though, which the t38x hasn't got
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
As you have described, it only works on OTA devices.

No other way on a Samsung device except going back to stock, which is pointless as you can just flash the update with twrp or install TWRP, back up every partition before making any mods( that includes not allowing changes to system) then restore everything except data at OTA time.

Stock recovery will also need to be flashed. (if you do this before backing up then you won't have to restore it manually each time.)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Red117:
May I ask what files you modified and how? my t385 uses T385DXU3CSH8 and i can see that the one you modified is T385DXU3CSJ1, i would like to adapt it to my specific boot image as i have had alot of errors flashing my device
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Talich52:
The modified kernel for the T380 model and the T385 model is laid out above. The kernel is compatible with any Pie Android firmware 9 of type T380DXU3C ... or T385DXU3C ...

I have already updated the firmware to T385DXU3CSK1 and applied the specified kernel, everything works great :)

This is a kernel based on the T380DXU3CSI5 kernel, as seen in the software section.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Flashing stock firmware should fix any issues booting.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Cheers dude appreciate the reply,

Wasnt to sure on tablet as I'm a phone repair technician myself, systems are slightly different to those of a mobile phone, and have never seen the second download mode screen before as I mainly work on exynos processors,

Have to wait until Monday unfortunately for the firmware downloads to be available again so will flash it back then,

Any rough idea on the new TWRP for the Oreo systems ?, unfortunately the tablet isn't mine and is a customers they are due to pick it up by Wednesday so was hoping to get it rooted for them but also test drive the new updated TWRP for oreo no rush or anything though I know myself from past experiences these things take time to be done and not everyone has alot of spare time.

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate,

So I downloaded the Binary 2 XSA T380 firmware,

But the BL wont flash for some reason I get fail every time, with SW REV FAIL aboot(fused)-2 binary 2,

AP & CSC However flash completely fine, using Odin 3.13 which supports oreo,

Any idea on how to fix this at all ? I'm stumped.

Thanks in advance
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Never known a bootloader with the same revision to be refused. Maybe it's the region variant.

In any case it doesn't need to be flashed, you already have a rev2 bootloader.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
none of this makes sense..

need instructions with even more details, been trying to make sense of all of this for months and can't, it is alot to take in.

someone pointed out earlier how lost in this some of us are, and I am one of those.

like maybe links to each piece of software involved.

specifics on their installation and setup if neccesary..

what does AP Slot mean in all these posts? I see it over and over again..

anyone in the L.A. area that understands all of this?

also, any chance you can stick the files to do this somewhere else? at top speed i am getting them at 38.6 KBPS, it keeps dying in the middle, tried downloading it now 6 times, twice from CA, twice from DC and twice from EU.. about the same all in all. (I am refering to the TWRP_3.2.1-1_sm-t380_15118.tar file).

has been in excess of 12 attempts now, i have a 10 MBPS connection here.

I could give you a log in on one of my domains if that would help.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Me either it's so strange but its specifically aboot.mbn that wont flash for some unknown reason I've never had an issue flashing the same either,

But everytime I flash the firmware to it, it just reboots back to the galaxy screen with Odin writing, very very strange indeed, starting to learn why I don't like Qualcomm now Haha I'm still so stumped, I might see if I can find a copy of the factory binary for the model see if that will flash the aboot from that, maybe it will clear the issue up hopefully,

With the region also from what ive read any T380 can be flashed with any region as they all use the same product codes, plus tab was bought in Australia and Is australian firmware I'm trying to flash, this is gonna be an expensive stuff up for me lol
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Acogu:
What's the full number of your firmware?

That happened to me when I was trying to flash the Nougat Firmware. We cannot go back once we flash Oreo. Apparently.

Anyway, just waiting for TWRP for OREO on the Tab A :fingers-crossed:

Cheers,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate,

it was the latest 8.1 firmware available and the only Rev002 that is available, I've noticed warranty but is also 0×fffffffe as well as qualcomm secure boot, that was why I was thinking I should get the factory binary on it as I've never seen that before on Samsung,

This is the firmware info from sammobile,

Model	SM-T380

Model name	GALAXY Tab A

Country	Australia

Version	Android 8.1.0

Changelist	14346227

Build date	Thu, 13 Sep 2018 10:39:34 +0000

Security Patch Level	2018-09-01

Product code	XSA

PDA	T380DXU2BRI6

CSC	T380XSA2BRI6

****edit****

Cant even get the REV002 factory binary to flash to the device, same issue keeps saying aboot(fused)-2 binary 2,

I'm so lost for words lol oh well maybe I'll just wait for the new twrp now to see if I can get a recovery workimg as I guess its mine now oosh $200 later after I reimburse the poor customer his money now oh well all part of the game, I'm gonna see if I can get it to boot the updated TWRP when its released and I'll see if I can put a custom rom on it would this work ? As the AP and CSC flashed fine even though they are listed as -2 and not just 2 also ? Who knows :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
ok, i feel like i am being ignored here, let me iterate this in another way..

some of us are visual learners, and no matter how much we read it makes no sense because we don't understand the basis or have anything to compare this too..

BUT..

if you made a video on how to install this we would understand in one shot.

can someone make a youtube video on this please?

thank you.

if you dislike youtube (and I understand and agree fully) I will even give you webspace to store it on if needed, but i must warn you i move from host to host every three years and next year i move again, but it give us somewhere to start.

I am working (or trying too anyways) with build # T380DXU1ARB3

and btw, multiple post about rooting the same device and disagreeing about how it is done DO NOT help, nor does it help when someone who was helped by another makes one of those posts rather than the one who provided the solution.

it has caused me major problems on my end learning to do this actually, and I am sure others feel the same, besides, it is a BS practice.

so ashyx you have time to make a 15 minute video or something on installing this?

if we can get you to do that, and the guy behind magisk to do the same we could make this alot easier.

and also noting which builds it is for and which it fails on would be good too, look at the posts by mingkee and shahmir_k, good example, but the post by shahmir_k show what I am speaking of in previous statement, the post should have been by Mefody so that that user had control over the post, not the one being helped.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate you'll have no issue flashing TWRP to your device just use the download link in OP to download the recovery as your REV001 so your device is compatible as your running the 7.1 nougat SDK, make sure OEM unlock is ON

Download a copy of your stock firmware for your T380 from sammobile.com you'll need it, any country is flashable but MAKE SURE that the firmware numbers are ☆T380ABC "U1" ABC1 and not T380ABC "U2" ABC1 for example as the new REV002 is 8.1 OREO you dont want that,

Once you have the recovery downloaded and also the stock firmware, make sure you have ODIN3 3.13.1 also as it supports oreo compression,

Now first load the TWRP.img you downloaded from OP and place it into the AP tab in odin3 3.13.1 make sure it is the AP tab, now select options, Uncheck auto reboot, now press start, wait for it to say pass In green,

Now you have to reboot the device but as soon as the screen goes black you must enter recovery without letting the system boot, on the T380 I have i use these buttons reboot the device,

Hold all at the same time

Home button,

Volume down button

Power button,

Keep holding until the screen goes black,

As soon as it does you have to be really quick and hold

Home button

Volume up button

Power button

You should now be in TWRP now just follow the steps as provided by the OP and you will be fine the hard part is now over,

if it didnt boot TWRP and you get a triangle screen flash back the stock firmware you downloaded and start these steps again from the start, to flash stock there will be 4 files, BL AP CSC & HOME_CSC, place the BL file into the BL tab, place the AP file into the AP tab (this will take a while to load this one) and last insert the the CSC into the CSC tab, flash and your on stock again, now start from the start,

---------- Post added at 05:29 AM ---------- Previous post was at 04:57 AM ----------

Hey mate I got it all fixed I managed to get everything back to 1 and not -2 like it was, apart from (R2) this was 2 when I received it but it's not -2 like it was,

Qualcomm secure boot and also warrantt void is not showing as 0×fffffffe thank #€£@ know what I'm doing just potentially averted a $200 loss lol, ah the Joy's of phone technician,

What I found wouldnt flash from combination rom when tried after downloading this morning it wouldnt flash the aboot.mbn, sbl.mbn, adspo.mbn,

what I did is disassemble the combination rom,

Took the following and converted to .tar

Persist.img

System.img

Userdata.img

Recovery.img

Sec.dat

Msadp.img

Keymaster.img

cmnlib.img

NON-HLOS.img

Rpm.img

tz.img

Then finally very last the cache.img,

Flash this last you will reboot get the spinning circle and it will reboot and everything will be back to normal for anyone else whom encounters this error, there is a fix to go back to 1 from -2 and have an operational system again :) enjoy guys I'll be waiting for TWRP oreo patiently and can tell my customer I didnt FUBAR they're tablet after all :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
Something doesn't seem quite right about the -2 revision.

I've never seen that before.

Are you certain this device is intended for the Australian market?

Certain Samsung devices will not flash other region firmware.

For example devices intended for the Chinese market or Hong Kong or carrier locked devices.

I would try and flash the Hong Kong firmware.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
I got it fixed with same XSA firmware see post above your one :), my guess is something got corrupt due to the 0×ffffffffe on warranty void and qualcomm secure boot had same issue on MTK with addresses being all messed up before, that's what made me believe if I can at least load the main partitions from the HW_Factory binary it will revert the corruption bu format,

I have never seen -2 either in all my years of repairing I thought it must be a qualcomm thing as I've only ever seen solid numbers but they're all back now :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
can i ask again.. whats an AP slot?

actually I asked that in the first post.

you all aren't getting it..

as a homeless man and a disabled person I can't afford to brick my tablet, and if i do then I am stuck with my laptop on my back and i can't.. it hurts too much.

everytime i put that much weight on my back i have to go to the restroom.

so i pick up a backpack, put it on, go to the restroom, take it off and use the ****ter (if there is one there, it has caused me to **** myself before) just to pick it up and put it back on my back again, sometimes i repeat this pattern a couple times, no joke.

http://abc.go.com/shows/secret-millionaire/episode-guide/season-2/04-john-ferber-los-angeles-ca << you can see me at 30 seconds in talking to the "secret millionaire", i will be in the camo jacket, he stared at my watch too didn't he? (he was actually there preying upon the poor, same as any that trade in debt. I been homeless 10 years now, my health is corroding. I really need to lighten my lode, PLEASE HELP ME DO THAT.

I need a good basic VIDEO on how to do this cause all this writing takes way too long to read and reply to back and forth for days and days when a video could make it simple cut and dried.

is it really too much to ask?

you wouldn't have to type to do it..

would be EASIER than typing actually..

in ENGLISH..

i can't understand these hindi guys..

and thats all you find.

EDIT: OK, I just figured out what you mean by AP slot.

what goes in the other 3? nothing?

I downloaded the stock file before i did anything else actually, it is the correct one.

the bootimage patch, it is done through the AP slot as well?

will this mess with the adaptable storage capabilities of this device? i have several SDCards i use, they are basically like hotswaps on a PC with this device when it comes out from the store.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
I am not good with people, that I readily admit, I am a terrible cynic, comes from years of being abused by my neighbors, god knows they started on me very young. But you know, it isn't a deliberate thing, nor is it intended as any form of an attack, just simple truth. If you take it that way I apologize, but that's not what is intended. (not right now anyways, but the point of a cynic is to abuse his neighbors equally, read up on Diogenes the cynic, cynic means "doglike" or "like a dog" btw.) They say I am mentally ill, I agree, as is most everyone else. (As is we really needed a doctor to come to that conclusion, LOL!!)..

those that actually know me refer to me as a dog actually, no joke.

but you know, I am serious about doing this, I think I have this part figured out, aside from the patch after, I will assume it is the same as the initial patch, now to figure out magisk and MM and how to make a custom recovery rom so that I wont have to do this again, I assume that is the purpose of a custom recovery Rom right?
