you have to press all three at the same time and hold them, it hurt my hands tbh.

what I ended up dogn was put my right thumb over home and my left thumb moving from down to up on the volume while my middle finger pushed on the power button.

I am eyeing the "root booter" app in the google play store because of it, would be convenient if it works right.

i installed the "no verify patch" but i did it in TWRP and it worked fine.

format, mount, patch and install magisk.

or do you mean you flashed it in the AP slot?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
On the bright side, while trying to get out of the bootloop to recovery, I have started a safe mode reboot to OS. It is acting like a new device, but in safe mode.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
might want to look under build to get your build number so you know which Rom to grab, if need be, hopefully not.

if it is booting see if you still have OEM unlock in options, and if not if the whole date and time thing causes it to show, if it does i would shut down after re enabling it fully and booting into TWRP from off, i find it easier than all the hand movements.

if not, flash stock and give it a week.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
Looks like all the numbers from Chile match (T380DXU1ARB3) with the same security patch dates. Gonna let this do its thing (update and restore and charge overnight) and try to reboot out of safe mode in the morning.

A sincere thanks to you guys for helping me with this device. I have been away from Sammy for a while and forgot how they do things (not as straightforward as LG and OnePlus!)

This is a well oiled trainwreck. Now I can't even boot back into safe mode or TWRP or DL mode. Just a giant yellow triangle and "Only official released binaries are allow to be boot" with a "Secure Fail Recovery"

This screen stays on if I charge while powered off, can't power on in any mode. Can't get official firmware for the build I have. But I can get to a newer one.

"Download the firmware for the GALAXY Tab A SM-T380 with product code XNZ from Unknown. This firmware has version number PDA T380DXU2BRI6 and CSC T380XNZ2BRI6. The operating system of this firmware is Android 8.1.0 , with build date Thu, 13 Sep 2018 10:39:34 +0000. Security patch date is 2018-09-01, with changelist 14346227."

That one is available. Would it work?

WARNING DO NOT INSTALL ANY FIRMWARE LABELLED WITH THE NUMBER 2

This is oreo firmware and you cannot return to nougat once done,

You can flash any region firmware to the device but just make sure its a 1, what country are you in ?,

Ill find you the correct sammobile link,

It will require reflash if only booting in safe mode or the big triangle screen with that writing,

Its not the no verity option.zip by ashyx,

Its due to you not originally formatting when TWRP was first flashed and booted,

Just dont flash the U2 firmware its oreo & this TWRP is not supported on oreo, i had a customers tab and tried to flash the recovery, somewhere somehow, all the AP SWREV fuses went to -2 not even stock U2 firmware would flash back i spent countless hours finding the fix to return the AP SWREV back to all solid 2's

Will this be ok?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Ill have a look for you ideally you should try and stick to sammobile but just make sure it nougat firmware with a 1 in the firmware and not a 2 any region firmware can be flashed to these tabs also hence the T380 xxxxxx 1 abcd

Xxxx = all the countries model codes, in this case is open to all hence alot of letters such as YDX for exapmle

Abcd = is an exapmle but all letter are to identify the firmware such as month version etc etc

Found some info on another thread that clarified Samsung's file naming rules. The USA variant is the "XAR" or "Cellular South" file. I was able to get the download started before I left for work this morning. I shall extract and restore in Odin this evening.

---------- Post added at 02:10 PM ---------- Previous post was at 01:54 PM ----------

I see where I screwed up now. Made assumptions. Bold entries on what I was thinking

To Root:

Flash the latest SuperSU or Magisk release with TWRP:

SUPERSU - https://xdaforums.com/app...2-05-t2868133/ Going with Magisk - I don't need this

MAGISK - https://xdaforums.com/app...mless-t3473445 Yeah...Igot the file already

To disable forced encryption and mount internal storage (/DATA): Do I even want to disable forced encryption?

(Note this MUST be flashed after SuperSU if you intend to root) I'm not using SuperSU, so this doesn't apply to me!

1. Boot to Twrp

2. Format the Data partition (NOT WIPE) using the FORMAT DATA button under Wipe options.

(Note: This will wipe the internal storage)

3. Check /DATA is mountable.

4. Install SuperSU (if root is required) Since I am going to root with Magisk, none of this applies to me!

5. Install boot image patch below.

6. Reboot

Boot image patch

no-verity-no-encrypt_ashyx

So you can appreciate where I went wrong. I didn't follow the procedure because it wasn't clear to me that the wipe was required, even if going with Magisk.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
That procedure is old, ill do a description here for you,

1. Enable oem unlock.

2. Flash TWRP, but make sure "auto reboot" is unchecked.

3. Boot to TWRP as soon as screen goes black when resetting without letting system boot at all.

4. Swipe to allow modification,

5. Tap the wipe tab

6. Tap the format button

7. Type yes and format

8. Wipe cache & dalvik

9. Back to main menu

10. Tap reboot

11. Tap reboot recovery

12. Tap dont install TWRP app

13. Wait for the tab to reboot TWRP

14. Tap install

15. Navigate to your magisk .zip

16. Flash the zip

17. Tap wipe cache/dalvik

18. Back to main menu

19. Tap reboot

20. Tap reboot

21. Wait for the system to load.

22. Go to the new magisk app in apps draw

23. Tap the menu button at top right

24. Tap settings

25. Enable "magisk hide" & "core only mode" if your not gonna be using magisk modules

26. It will prompt to reboot after enabling core only mode ignore this,

27. Tap repackage magisk manager with a random package name & wait for it to complete,

28. Reboot the tablet

29. Go back to magisk app, and to menu again

30. Tap magisk hide, now select all apps you want to hide root from and reboot after for all changes to take effect.

Im an android technician and run my own shop have been flahsing with magisk for years now,

What magisk has to offer,

•Magisk hide.

•Google play saftey net pass.

•Makes system think knox warranty is still 0×0 internally

•has no verity encyption built into magisk

super user

• wont pass google safety net check.

• dosent have hide like magisk.

• system will display with knox tripped

• Does not have no verity built in

Go magisk do it with the steps provided & your golden, ive successfully rooted over 30 devices with magisk just this year alone :)

Just make sure your firmware is nougat and has a 1 in it if you flash oreo then TWRP wont work at all ever until ashyx releases the new updated TWRP to support it,

In which still waiting patiently to add it to my collection lol customer is to it seems phones in every week to check haha
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
I know I am getting off topic, but this could be helpful for anyone else who screws this up like I did. I downloaded the firmware from Sammy and unzipped it. There are 4 files, AP, BL, and two different CSCs. No CP file, which is the Modem...do I need that? Did I get an incomplete file?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
I have survived myself. I used Odin to flash AP, BL, and a CSC. Long first boot, but booted. Back to stock everything. Now I am in "OEM Lock Time Out" for a week.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate,

If you do the wifi trick you wont have to wait the 7 days,

Yep is normal not to have a CP file with this firmware, Only as Samsung have intergrated the modem into the AP file,

BL= Bootloader file

AP = main system and some others

CP= modem

CSC= apps & data

The diff between the CSC & HOME_CSC is that using CSC will wipe all your data and apps HOME_CSC will not,

Do the wifi trick and oem unlock will pop right back up for you then just follow my steps :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] duckredbeard:
I tried the manual date/time set with no success...what is the wifi trick?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Im not 100% sure on it myself but capriorn1971ad seems to have had much success with it on all of his failed attempts,

I do remember saying to get rid of developer options again and then re enable them and should show,

I beleive if you go to settings tap apps,

Scroll down to the settings app, tap on it, then tap storage,

Now clear all data, soon as you do this it wipp return to the home screen,

Now go back to software info and tap on the build number to enable developer options again after the wifi trick and it should be there
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
the trick is to set your date to a different date, then readjust the date and time automatically connected to the internet to force showing OEM unlock after 7 days (when it doesn't show right away as it usually doesn't), turning on and off developer options as needed to get it to show right away.

weird thing though, on my device that i rooted, i waited the 7 days for OEM unlock to reappear and i made sure ti was enabled and it popped up enabled to start with (didn't expect that personally, but was relieved it was that way) but after a reboot my OEM unlock option is gone again.. doesn't matter anymore though does it?

the whole wifi / time and date thing, it is kind of like when you own a dog and he poops on the floor you rub his nose in it, basically what your doing is setting time and date to make the tablet consider how long it has been, and it seems to work.

it wont get you out of the 7 days initial wait though.

so Matty, what do you think about this tablet not showing OEM unlock again? only reboot it once a week till the end of time? (meaning when OEM unlock reappears). It shouldn't have disappeared should it? It was 7 days ago it was rooted and left unbooted til the OEM unlock was there and then it was gone after the reboot.. wiped 8 1/2 days ago now.. or is this normal?

I just noticed a page about OEM unlock talking about the same date and time thing, look: https://www.theandroidsoul.com/galaxy-s8-s9-note-8-oem-unlock-option-get-it-back/

that was posted july 5th of this year, hadn't seen it before but common sense dictates.. this is a common sense thing really, simple logic, you want the tablet to consider time, adjust the time and date and make it readjust it back correctly (forcing it to consider).

maybe his explanation of it will work for you, my language usage isn't always the best.

heres another post about the SAME EXACT thing, but taken to a different extreme to actually BYPASS the 7 day wait..

https://www.the***********.com/fix-missing-oem-unlock-toggle-samsung-galaxy-devices/ (the custom droid dot com (all ran together))

same thing, but he went back a month and then autoadjusted forward to correct, i hadn't considered that myself.. that means the 7 day wait is null and void.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Ive seen it quite often it may have something to do with magisk's debloater script as it can sometimes make the settings menu look funny,

Once your rooted i personally wouldnt worry about the OEM unlock option not appearing, all this does is renable FRP lock and locks the BL down again,

As you have a TWRP recovery installed this is a custom binary, if you toggle OEM unlock back off you will lock the bootloader down again and while you have TWRP on the device it will trigger device security and on reboot you will be at either the triangle screen or youll receive recovery blocked by frp lock and the device will no longer boot,

Could also be the firmware now, samsung are actually introducing new security called DEFEX to stop device rooting and custom roms and what not so may be a tamper switch run off an internel software flag maybe,

But just make sure to leave OEM unlock set to on and only toggle it off if you plan on going back to stock unrooted
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
yeah, i think i will give it the time it needs to show back up, shouldn't be any more than 8 days, just to be safe.

I wonder if i set the clock back a month like the guy in that post did if i can get it to reappear..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
good call, i got the triangle.. oh well, i have extra time today, time to fix this again and reroot, again..

don't know what i did exactly.. wish i did so i would know not to do it again.

was kind of a flaky root anyways, i really though it didn't take to begin with.

time to reflash stock and do this once more.

if i had been thinking further ahead i should have backed up the system barebones in Titanium backup, i do have it, i think it would have reverted it, i am unsure though.

Hi,

Will this work for SM-T380NZKEXAR with Quad-Core(1.4GHz) Qualcomm APQ8017 or Processor Model Exynos 5433? There is a sale and I like to know before I get it.

Thanks.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hi there,

All T380 are the same mate any region firmware can be flashed to the device as they are not region specific,

The only thing i would make sure of is that it has got android 7.1 installed,

TWRP is not yet compatible with android 8.1 oreo what so ever as it will not boot and may cause damage,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] powder_7:
I getting it from bestbuy so it's most likely an USA model. Can I still install TWRP? I am more familiar with Android phone and know att samsung Android phones are lock.

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

Just make sure its got android 7.1 Nougat on it and not 8.1 oreo,

Nougat yes TWRP will work 100%

8.1 Oreo no it will flash but the recovery will never boot and may cause some soft damage which is very difficult to fix,

TWRP has not yet been updated by the developer #ashyx to support 8.1 oreo just yet, he is currently in progress on the changes to support it

Just ask at the store or look on the box for 7.1 or 8.1, if they have a display model go to settings on it then to about tablet and see what OS its running.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] cmzizi:
Can we get this for P580 Oreo?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Hey mate you need to ask on the appropriate forum this is for T380 specifically,

You have the Tab 10.1 2016 model i do beleive youd be best to check out the TWRP website in regards to your model or click on the link below for the xda thread to your model.

Thanks and enjoy your day :)

Thanks
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Matty1993:
Scroll back a few pages capriorn1971ad wrote instructions on one of his posts on how to do it :)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] powder_7:
Just to confirm that there is not work around for the initial 7 days wait? Does the tablet need to be on for 7 days without reboot or shutdown?

Thanks,
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
did you try setting the clock backwards a month?

if you have luck with it let us know.

you can reboot in the seven day period, it is after you flash the rom that you can't reboot for 7 days, or until the OEM unlock pops back up anyways.

if you reboot before the OEM unlock shows back up it will give you the droid and triangle screen when you reboot and you have to start all over, flashing the original rom, doing a factory reset afterwards (to correct size of device issues) and waiting again, unless you can manage to fool it into thinking 7 days have passed.

when you do the factory reset after the initial reflashing of the stock rom I would set the clock backwards at that time so it shows as having been done at that time, auto-updating time online later, but not during intial setup if it can be avoided.

you should uncheck "autoupdate" under settings before you root it as well, and avoid that section of options after that.

good luck.

yell if you need anything.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] powder_7:
1.) Got new system 1 day old. Went thru initial setup with google account.

2.) Enable development option by pressing the building number in about. But OEM unlock not show.

3.) Turn on airplane mode. Try to set date back 7, 10 and 30 days.

4.) Turn off Development Option.

5.) Restart.

6.) Change date to today but will not save after Restart.

7.) Turn off airplane mode. Change date to today. Restart.

8.) Turn on Developer Option.

9.) OEM unlock not show.

Still not working. The above is the combination that I try.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
But considering you got it today.. you still didn't do the factory restore with the date set back..

7 days isn't long.

Doing a restore with the date back 30 days should be a good start.

Most you lose is a few hours.

It's a shame Samsung is like this, after all it is our devices that we purchased.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Tami Andranunes:
I followed the steps, I managed to do root, but when restarting the tablet, it gave error with the message "only official released binaries are allowed to be boot - secure fail: kernel".

I already tried to reinstall factory firmware but it also displays an error.

I can not connect it again.

How to fix?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
Put the tablet into Download mode first:

1) Turn off the device (if you can't get it to turn off proceed to step 2)

2) Press and hold Volume Down key + Home Key, while pressing these keys then press and hold Power key for a while

3) Release all key when you see ODIN Mode / Download Mode

4) Use Volume Up key to continue

5) Use Volume Down key to cancel ( Restart the device )

get the original rom, flash the ap file in the ap slot onto the tablet (set the tablet into download mode first).

reboot, then after setup do a factory wipe so it shows the correct size.

after setup my 32 GB tablet shows as a 8GB tablet, the factory wipe resets it to 32GB.

after you root the tablet DO NOT reboot the tablet for 7 days (until OEM unlock reappears in developer options).

rebooting before the OEM Unlock reappears results in exactly that, the triangle thing.

you might want to set your clock back a month before you do it, so that you may be able to trick it into letting you rooting it faster.

I will try a new update of room 7.1.1.

I used Brazilian version (because I'm Brazilian) - T385MUBU1AQL1_T385MZTO1AQL1_ZTO;

I saw that it has an updated original version (T385MUBU2ARF1_T385MZTO2ARF1_ZTO).

But the question is:

I also saw that it has the original version 8.1.0.

Does root work in this version?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] capriorn1971ad:
matty is using it, as far as rooting it goes i beleive it has issues.

maybe matty will tell you about that, i for my part NEVER update my android OS's (I have on 2 occasions and regretted it both times).

if you have already updated that may be why it messed up, IF you can get it back to 7.1.1 you should be ok, i am unsure if it is capable of being rolled back though myself, Matty would know that much better, but he is on Aussie time, hopefully he will reply in a few hours when he wakes.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Tami Andranunes:
I was using the previous version 7.1.1.

I had done the root and it worked until I rebooted the device.

Since then the error message has appeared.

I tried to reinstall the same version as it had original, but it gave error.

Now I'm hoping to download a new release and try again.

edit: I made the installation of the new version 7.1.1, to be able to return to the normal state of manufacture (finally). Now I have to wait 7 days to unlock the OEM.

The root installation is not completely clear. I ended up committing the error in the installation of "no verity", it seemed to be rooted until restarting the device ... when it came the error secure fail: kernel.

and sorry for my bad english :|
