[Samsung Galaxy Tab A series Guides, News, & Discus] SMzeeshan:
No, Android 11 is not out for SM-T295 yet but I want to root my device only after android 11 update to avoid other problems. Thankyou so much for replying but the link you gave me, I already checked it and it is tooooo complicated for me😅.

I want to root this tab just so that I can provide signature level permissions to sideloaded apps to make them work (As this tablet has stupid One UI Core, no Good lock modules or Bixby apps work).

Is there a way to provide them signature level permissions or convert them to system apps without root? Can we do that in Twrp by moving .apk files to /system privileged without root? If it is possible just by Twrp and works well then there is no reason for me to root my device.

Please share any information you have. And Thanks once again 🤍
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
You can only install TWRP and not get Root rights. But you still need to change the bootloader to the one taken from android 9 and the patched vbmeta file ... You will also need to make format data and install the Fix_vendor_10 patch from TWRP to access memory ...

The clarification! when installing TWRP, you must patch the stock kernel, because otherwise the built-in protection will not allow you to boot,there will be a bootloop :( For the kernel patch, you need to apply Magisk.zip, that is, you will have to root it... ;)

And most importantly, a quote from a knowledgeable user:Waseeam,:

There are no solutions and no matter what was bought - a tablet or a phone, if it's a version of Core that is not one third-party app stock or modified will not work - ie after the installation of the system will be notified that the application is not compatible with the device and you can install only two apps not galaxy store and google play is a calculator and galaxy store and all other apps can be installed or upgraded only in galaxy store and google play.
[Samsung Galaxy Tab A series Guides, News, & Discus] SMzeeshan:
What do you mean by changing the bootloader to the one taken from Android 9? Do I need change/modify the vbmeta and tar files or can I directly use them from the video as they were made for Android 9? Where would I get Fix_vendor_10 patch?

And after I do all the things you mentioned, will I be able to provide apps signature permissions? Please explain the procedure in detailed steps and simple words. Sorry but I am new to this Rooting stuff and don't have any experience.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
On Android 10, it is impossible to root the device because of the enhanced protection, you have to change the bootloader to android 9... Above I added the message, even setting TWRP and Root-rights, will not be able to solve the task... But you can try :)

PS files will be found in the topic of rooting T295, the link was given above...
[Samsung Galaxy Tab A series Guides, News, & Discus] SMzeeshan:
Thanks for giving a detailed clarification which made it easier to understand. But it is disappointing to know that there is no solution to turn One UI Core to One UI😕
[Samsung Galaxy Tab A series Guides, News, & Discus] markboston:
so whats the tldr here? is this unit capable of being rooted? this is the version i bought SM-T290NZKAXAR. doing a search of that model on xda gives me nothing useful.
[Samsung Galaxy Tab A series Guides, News, & Discus] anony055:
Yes two distinct steps.
[Samsung Galaxy Tab A series Guides, News, & Discus] anony055:
Yes, I have successfully rooted, SMT290 , Android 10.( Magisk and Twrp)

I have posted instructions on rooting in this thread above.
[Samsung Galaxy Tab A series Guides, News, & Discus] Heeni:
Has anyone else with a T290 ended up unable to set a screen lock after installing TWRP? Or, for that matter, has anyone been able to install TWRP and NOT have this problem?

Every time (and I've tried a few times now) I install TWRP, I can no longer set a screenlock. I'd love to know what I'm doing wrong. :(
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Doing everything right, but forget that Samsung security service will not allow you to enable screen lock protection if you have TWRP & Root on the device. And the T290 / T295 is no exception ...
[Samsung Galaxy Tab A series Guides, News, & Discus] Heeni:
Thanks. I didn't know that, and I don't think it's for lack of reading. :)

Are there any workarounds available? Or, for that matter, are there any other ways of installing custom ROMs that don't involve TWRP (and which would allow screen lock)?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
With custom firmwares on the T290 / T295 it's bad, they just don't exist ...

In this case, you can have a rooted or custom firmware and with a stock recovery. ;)

I have no more detailed data ...
[Samsung Galaxy Tab A series Guides, News, & Discus] Heeni:
Thanks. I can stop driving myself crazy trying to find a fix. :)

I've had no luck with installing a custom ROM with the standard recovery. I did manage to replace TWRP wiht the standard recovery after I'd installed a GSI ROM, but it made no difference.

What strikes me as odd is that no one else has mentioned this. Maybe only very few people bother with screen locks. :unsure:
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
I just got a SM-T290 and I cannot figure out for the life of me how to unlock the bootloader. I have USB debugging enabled and OEM Unlock enabled, and when I use

adb reboot bootloader

I get the Samsung Galaxy Tab A screen with

CURRENT BINARY: Samsung Official
OEM LOCK: ON (U)
etc etc
download mode !!

The only other screen I can get into is stock recovery; if I turn off the tablet, then plug it into the computer while holding the volume buttons down, I just get the charging screen, and if I power the tablet up while holding both volume buttons down, it boots into safe mode. I obviously can't flash TWRP or a custom ROM because the OEM lock is on.
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Have you seen the Magisk installation notes? There's a section on unlocking a Samsung device.

I think, when in the download mode, hold Volume Up.
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
I tried that. No dice. It may be because it's a Snapdragon device?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Okay, there's one more step left. Turn off the device, hold down both volume buttons and connect the cable from the computer. A blue warning screen will appear, you need to press the Volume + button for a long time (10 seconds) and release. The device will go into reboot with data reset. After restarting, turn on the Internet and enter developer mode, if unlocked the bootloader is successful, the OEM Unlock option will become inactive and a warning screen about the unlocked bootloader will appear on reboot. :)
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
The only thing that happens when I plug it in while off is it shows the charging screen. I can access bootloader, download mode and recovery, but holding both volume buttons does nothing.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
First you need to press and hold both volume buttons and then connect the cable from the computer ...

How do you get into these modes?
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
As I believe I mentioned, doing this only results in the charging screen; the tablet does not boot automatically when plugged in.

By using ADB while the tablet is booted into system:

adb reboot bootloader
adb reboot download

I haven't messed with it in a couple days but I believe holding volume down while booting forces it into recovery mode.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Read Section B. Unlocking Bootloader,

The order in which the volume buttons are pressed may matter :

https://xdaforums.com/t/17jun20-gui...-flash-twrp-exynos-only.3960031/post-80116925
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
Ok. Just tried a couple things. Still no joy.

Powered tablet off. Held volume +, then volume - and plugged tablet in. Got charging screen.

Used power and volume - to boot. Booted into system.

Power and volume + boots into recovery. Selected "reboot to bootloader".

Buttons do not do anything in bootloader, except holding down power reboots tablet.

The only way to get into download mode is via ADB, and again, the buttons do not do anything.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
You need to press and hold Both volume buttons at the same time, and not in turn.
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Is OEM unlocking still turned on in Developer options?
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
Sure is

I just got a SM-T290 and I'm running into the same issue trying to unlock the bootloader. Volume Up Down while plugging it in does nothing for me either.
[Samsung Galaxy Tab A series Guides, News, & Discus] mindfrost82:
I got it. I was holding the volume keys while plugging the USB cable into the tablet.

Instead, leave the USB plugged into the tablet and unplug it from the computer. THEN hold Vol Up and Down at the same time while plugging the USB back into the computer. This got me to the warning screen and I could follow the steps to unlock the bootloader.
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
With it powered off?
[Samsung Galaxy Tab A series Guides, News, & Discus] mindfrost82:
Yes. I had it powered off. The USB plugged into the tablet but not the computer. Hold both volume buttons and plug the USB into the computer and it'll power on by itself.
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
Confirmed, this worked. Thank you!

Can anyone help me, I have a brand new T290 with a week old, it came with firmware T290XXU3BUB2, with security February 2021, I read on previous threads I have to downgrade first the bootloader, where can I find those files for it?

Thanks
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
The bootloader version cannot be downgraded :(

In this case, you need to use a bootloader from android 9 of the same version 3 ...

I will attach:

[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
First, change the bootloader to the one laid out above from android 9, then flash TWRP and enter it as described:

[Samsung Galaxy Tab A series Guides, News, & Discus] Azev:
Thank you for quick reply. I must to reboot between flash of BL and Recovery?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Can be flashed in one go by selecting files as BL and AP parts
[Samsung Galaxy Tab A series Guides, News, & Discus] Azev:
TWRP can't boot, when i choose recovery in the menu it boots on DL mod with Samsung boot screen. I let it boot and retry.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Yes, that is right! I use this to enter bootloader mode.

And the entrance to the rekoveri is described in my message from the link above.
[Samsung Galaxy Tab A series Guides, News, & Discus] Azev:
Finally it has boot with holding + volume button only but it is russian...
[Samsung Galaxy Tab A series Guides, News, & Discus] Viggen66:
So you have the same tablet as I do, it came with T290XXU3BUB2, so firstly I need to unlock the bootloader, which is straight forward, after that go to Download Mode, with Odin,

BL: aboot_vk_T290XXS3ATF1

AP: twrp

Btw, where can I find twrp compatible with this tablet, and I want to flash a GSI Rom, which version should I flash Android 9 or 10?

Is possible to root those new roms, since on GSI if i'm not mistaken the kernel remains the same?

Regarding GSI roms, are the SYSTEM AS ROOT and A only compatible with this tablet?

Thanks for all
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Somewhere laid out in the subject ...

I will attach an option for installation via ODIN:

I won't tell you about custom ... I prefer a rooted stock firmware with a slight modification ...
[Samsung Galaxy Tab A series Guides, News, & Discus] Azev:
It is ok tablet rooted and safetynet passed
[Samsung Galaxy Tab A series Guides, News, & Discus] Viggen66:
Thanks, so Odin files to flash are as follow, on dowload mode:

BL : aboot_vk_T290XXS3ATF1

AP: TWRP+vbmeta_T290
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Yes, that's right. After uploading the files, enter TWRP, install Fix_vendor_10.0, execute format data (no wipe data), install the current Magisk.zip, boot into the system and use :)
[Samsung Galaxy Tab A series Guides, News, & Discus] Viggen66:
Thanks, heard and read horror stories about this tablet, after all with your help is not that hard.
[Samsung Galaxy Tab A series Guides, News, & Discus] Viggen66:
Is any way to remove the press of power button to boot the tablet after bootloader is unlocked?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
There is :)

Just wait a few seconds ...
[Samsung Galaxy Tab A series Guides, News, & Discus] Viggen66:
I have already tried to root my T290, firstly install TWRP, from a method from another thread, without the need to change bootloader, but I only got a black screen, no image, nothing, I thought I had bricked my tablet, luckily I had memorized the steps on how to go to download mode, pressing volume up and has able to flash again stock rom, I'm a little bit skeptical, about this tablet now.
[Samsung Galaxy Tab A series Guides, News, & Discus] Aballamis:
I have successfully installed twrp(first I used the twrp+vbmeta_T290, but later found and currently using twrp-3.5.1_9-0-T290XXU3BUB2-20210330.tar as it is more recent and thought it may help as I am on T290XXU3BUC1) AND Magisk 21.4 using zip file in twrp. In Magisk Manager under ramdisk it says "no" but seems to work just fine. Root apps authorize and work.

My issue is that even though I flashed the fix_vendor_10.0 and format data, now after having flashed Magisk and set the tablet up, when I boot to TWRP it still prompts for system modification AND sdcard is still encrypted. So I'm not sure about flashing my audio mods and other goodies, as I suspect it could cause problems or not work as /data is encrypted.

Is this standard or no??? Also, after I flashed the fix_vendor it failed to format data and unencrypt. I had to reboot to recovery and then format data, which worked. Then may have rebooted recovery again to flash Magisk but can't remember. Did I mess up using the later twrp? Or elsewhere?

Any help greatly appreciated!
[Samsung Galaxy Tab A series Guides, News, & Discus] Aballamis:
Here is the TWRP I'm using, and what about this twrp multidisabler from the twrp 3.5.1 thread???

Edit: for the life of me I cannot get it to let me attach the actual twrp file . . . But it's 'twrp-3.5.1_9-0-T290XXU3BUB2-20210330.tar.md5'
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
I recommend installing TWRP from mehanik6, then log in to TWRP, do format data-yes (not wipe data), install Fix_vendor_10, reboot into recovery and check that the memory is available by selecting Another-file manager-sdcard, that there are no folders with unclear names, boot into the system :)

P.S. Sometimes you have to additionally reboot into recovery (TWRP) and do format data again

hello,

i'm trying to root my T290 T290XXU3BUC1 on last version of android 10

bootloader is unlock (i got the message at boot)

i can't update bootloader with odin (security check)

i patched rom with Magisk and i can't install it (security check)

i tried to install TWRP twrp+vbmeta_T290 and a i got a vbmeta error when i try to install it

i saw that some people installed Fix_vendor_10, how can i do that ?

is there a way to root it ???? please need help !
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Everyone gets a vbmeta error on the display, but at the same time in ODIN there is a PASS display, which means that TWRP and vbmeta are flashed and you need to enter TWRP without rebooting into the system, otherwise stock recovery will be restored. The vbmeta error is written by the security system, but this is only a warning that should be ignored;)
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
This file must be put on a memory card and installed from there via TWRP, and also execute format data-yes (not wipe data) to disable encryption ...
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
ok

but i can't install TWRP :-(

i downloaded twrp-3.5.2_9-0-T290XXU3BUC1-20210516.tar.md5 and odin modded....

i have to flash TWRP in AP or BL mode ?
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Explain "odin modded".

TWRP is a recovery. The twrp.tar.md5 file should go in Odin's AP slot.
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
flash with this file : twrp-3.5.2_9-0-T290XXU3BUC1-20210516.tar.md5

reboot in recovery but i hava a black screen ! and no possibility to do something

ADB devices report me that the tablet is in recovery mode....
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
i found an odin modded version !?

so, i brick my tablet ;( black screen !

i try to flash ap with original ROM but not the BL and i don't know what to do ?

adb devices report nothing

odin cannot connect to the tablet, i think i'm with android not configured and a black screen...

Try flashing a different TWRP version:

https://xdaforums.com/t/root-for-sm-t290-tab-a-8-0-2019.3965624/post-84814059

If the display remains dark, that is, there is only backlighting, but there is no image, then the device has protection about which they write on the last pages of the topic ... And how to solve the issue is unclear :(

P.S. yes, this is a patched version of ODIN, but this is not required, I will attach the latest version of ODIN, which I myself use all the time ...
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
i restore it !

i'm going to try another TWRP !

i'm not feel well with Android :(

if i can boot on TWRP, i have to put on the flash (before or after ? ) the file fix_vendor.zip and format data ?! i'm right ?
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
with TWRP file test_twrp_t290.zip i got a security check error

with twrp-3.5.2_9-0-T290XXU3BUC1-20210516.tar.md5 black screen

i just have to flash TWRP in AP mode, reboot with VOL+ pushed ?

thxs to all !
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
It is better to register the necessary files on the memory card in advance and insert it into the device ...

The necessary files Fix_vendor_10 and Magisk.zip of the current version to immediately root the device ... If you do not use Magisk, you will not be able to boot into the system ...

tcintd said: i just have to flash TWRP in AP mode, reboot with VOL+ pushed ?

It's so easy not to enter TWRP when the bootloader is unlocked ...

I’m just waiting for a twrp working for my device

With black screen it’s impossible to root it
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Are you sure you can't install Magisk?

After flashing magisk-patched-AP.tar file (and the other three files) in Odin, ignoring the "SECURE CHECK FAILED: vbmeta", make sure you go straight from download mode to recovery mode to wipe data. Then struggle to boot towards recovery, releasing the buttons at the right moment so you actually trigger Magisk. Every time you get to Android, run the Magisk Manager app and see if it says it needs to do some more setup. Let it do some more setup.
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
I tried different methods

Patch with magisk the original rom and flash it with Odin = can’t boot security check

With different TWRP files I got security error or black screen when I try to reboot in recovery mode

It’s working with the last TWRP files but with black screen

If you have another method, I ant it :)

[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
When do you get "security check"? While running Odin? When booting to recovery? When re-booting to Android?
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
I get security check when I’m booting in recovery mode and when I’m booting to android

It’s a big red message in the top of the screen

if i'm using stock rom i can go to recovery mode, but can't install zip files due to security locks

next test : boot with last TWRP (Black screen) and use ADB command to install zip files !?

ADB SIDELOAD Fix_vendor_10.0.zip

ADB SIDELOAD Magisk.zip

do you think that it should be work ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Can you take a photo with another device and upload it?

Or write the text of this message here?

Is the bootloader unlocked exactly? In firmware mode, what's in the OEM LOCK line:?

and is there a line KG STATUS:?
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
KG Status is Checking

Secure check fail : recovery.img
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
perhaps there is a way to downgrade bootloader and get TWRP working ?

is there a security check in the bootloader that disable the screen (black screen) ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
KG STATUS: Checking does not interfere with TWRP installation and device rooting ...

On the device, firmware 10 android, in order to root it, you need to replace the bootloader with 9 android, otherwise the security system will not allow using TWRP or a custom kernel ...

Flash the BL file from the previous Android 9 firmware via ODIN as part of BL or AP.

Good luck!
[Samsung Galaxy Tab A series Guides, News, & Discus] patmasxda:
