If Wi-Fi is not restored, then contact Samsung service. First install the stock firmware and lock the bootloader, there will be no traces of rooting...

P.S. The Reset button in ODIN to clear the windows of ODIN itself. There is a data reset procedure in the CSC part. Also reset the data from the recovery mode.

And what stock firmware is currently installed?

This is the currently installed firmware, I feel this firmware is little bit laggy, the ONE UI freeze sometimes when boot up.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
How did you do it? The user did this on purpose, and then asked for help.

You can restore the mmcblk0p48 & mmcblk0p61 partitions through TWRP with its built-in file manager or through adb mode at: / dev / block

P.S. But I would first unload these sections and compare with the attached ones. If it is empty, then it makes sense to restore, otherwise the problem will deepen.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
This is an old firmware and you can install a newer one, but if you want to leave the possibility of rooting, then do not upgrade the bootloader version, that is, just do not use the BL file from the new firmware.

IS THERE A TWRP FOR VERSION T295XXU4CUF8?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
TWRP version does not depend on current firmware, just find and install TWRP for T295 model.

However, the current bootloader version 4 will not allow the device to start and TWRP. This can only be done with android 9 bootloader, but it cannot be installed as version only 3, below ...

[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
The problem is not in android 11, but in the 4 version of the loader and now the loader of version 3 of android 9 cannot be installed.And the protection in Android loaders 10 and 11 is enhanced and does not allow you to install either a custom kernel or a custom TWRP recovery.

You need to flash 2 files by selecting them as part of BL & AP in ODIN.

Before flashing, unlock the bootloader, and after flashing, update or install MagiskManager version 24.3

Hey man i am on android 11 BL V4 and i cant seem to be able to flash ANYTHING other than the stock rom no twrp no magisk patch AP

Also when i try to flash thr Android 9 BL (version 3 I guess) it doesnt let me. Says Sw rev check fail fused ? Binary ? (There were some numbers like 4 or 3 in place of "?" But i dont remember them) bit of research and i discovere there is a roll back protection on samsing device....?!

So does this mean its over for me and everh android 11+ Samsung user and there is no hope for rooting??
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
With version 4 of the bootloader, neither a custom kernel nor a custom TWRP recovery can be installed due to enhanced protection. It's not possible to downgrade the bootloader...

What are the prospects, I don’t know, since the same user, well, perhaps more experience. But the T295 model was unpopular with customers right after the release, and now even more so ...

Because we are moving towards a future where we won't own anything, even if we paid for it. Live services have been blurring the line between end-user ownership and IP protection for a while now, and soon we'll have physical hardware that we *own* but may not necessarily have full access to because we didn't subscribe to their post-sales services. The video games industry has already caught this plague.

[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
AFAIK the only difference between the T290 and the T295 is the latter's LTE connectivity. Kernel should be the same, so I would think that TWRP for the T290 should also work on this device...in theory.

Here's how to get it installed:

Connect your device to your PC and start Odin. It is ideal to use a microSD card with Multidisabler and Magisk on it.

Perform a fresh flash of current firmware.

When the device reboots, hold Volume Up to force it into recovery mode. Do not allow the device to boot to system.

In recovery, select Reboot to bootloader.

Reset Odin, and flash the TWRP image in the AP slot. When the device reboots, you'll get an orange Unlocked Bootloader warning screen; click Power and hold Volume Up again to enter TWRP. Do not allow the device to boot to system.

Flash Multidisabler and wipe data + internal storage. MTP should work if you need to transfer files to the device.

If you intend to use Magisk on the stock firmware, I suggest rebooting to system and allowing the system to boot before flashing Magisk.

If you get a failure when flashing TWRP: "Only official released binaries are allowed to be flashed", you will probably see KG: PRENORMAL in the upper left corner. If this happens, you'll need to allow the device to boot into system; go through the setup, then enter Download Mode again. The KG: PRENORMAL should have disappeared, and you should now be able to flash TWRP.

If you attempt to flash Magisk before flashing Multidisabler, the device will fail to boot and you'll only get a "Only official released binaries are allowed to be booted" screen.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Yes, the T290 & T295 recovery work on both models, this was written at the beginning of the topic ...

But the problem is not in TWRP and not in the kernel! The T295 kernel is patched by Magisk without any problems, the whole problem is in the T295 bootloader, only with android bootloader 9 you can install a custom kernel and recover ... In this, the T295 bootloader differs from the T290 bootloader, it is impossible to install a bootloader from T290 on T295.
[Samsung Galaxy Tab A series Guides, News, & Discus] V0latyle:
The same problem is present on the WiFi model, if you allow the system to boot after flashing it'll overwrite recovery and throw a fit about a patched boot/system image.
[Samsung Galaxy Tab A series Guides, News, & Discus] barpasc:
I tried to flash TWRP in the T295 U4 android 11 bootloader but no success. I had to reflash a stock ROM and now the phone comes with apps that were not there before (mail.ru, yandex...):confused:.

I downloaded a ROM for France but to mention all steps, after not being succesfull with TWRP, I flashed a chineses rom from a ealier post that says it's a light rom without google and low on battery in this thread but the phone wouldn't start because of PIT missing file.

Now I have this phone with apps I have no ideas how they arrived there. I am sure I have never seen these apps before. Anyway, above that these facts, the fact that the initial android setup requires a cell or wifi connection is something I don't really like...

So I am about to pack everything back in the box and send this device to second hand market. This was initially a gift I made a couple of years ago but the personn didn't use it at, it was just sitting for days and months without being used...

I'll clean manually the apps using adb so the device looks nice new but I think if the next user resets it, these apps will come back automatically without asking. Anyway, not everyuser will reset. I'll then look for an older device or maybe T295 with U3 bootloader on android 9 to see if recovery can be flashed first thing and lineage os can be installed for instance.

It seems things have changed since I played noob with galaxy note 3 and safestrap which worked on verizon devices, I don't know where the dev team or dev is now. It was ported to a few devices but android or the dev as changed things. Anyway this was a time with android 4 jellybean, cyanogenmod, CWM recovery...with older devices, these dev made almost anything possible:cowboy:.

Now with newer devices, things are locked by the manufacturer and the android os. Lineage os is a continuation from an earlier period but this is a case with T295, spending hours in a day to get nowhere is somehow frustrating. At least I could see things have changed after quite some time not flashing devices.

Thanks for your help anyway🙏🙏
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Everything is simple here :)

You installed the firmware with the OXM multi-region, but previously there was another multi-region. Accordingly, you received the default region SER Russia and a bunch of applications required for installation such as mail.ru, yandex and others. I will attach the list of regions in OXM and the default region...

You need to flash the firmware for Vietnam with OLM multi-region, or change the current region to XEF France and reinstall the OXM firmware.

I also recommend Chinese firmware, but install only parts of AP & HOME_CSC! Others cannot be installed, because the T295C model is different and the PIT file is different.

P.S. To change the region, use the attached program...

I have the 290 and followed these: https://xdaforums.com/t/rom-twrp-sm-t290-sm-t295-discussions-help-thread.4031223/post-82487731 instructions to try and obtain root.

Everything worked well after changing the file sizes in the lz4 with the --convert-size step.

When it rebooted I was greeted with this:

So I reflashed back to the originals and am stuck.

I did a bit more reading and some threads are saying to be very careful and not let the system reboot on it's own but after using Odin to ensure it loads back to bootloader EDIT_23-8-22 not bootloader, should be boot to recovery.

Can anyone tell me if that is why I got this issue please?

Cheers everyone, this is a very frustrating excercise for all concerned........Tony
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
I don't know how that procedure differs from the procedure described in this thread.

I do know that when I installed Magisk, the instructions said do not let Odin reboot. You were supposed to uncheck the "reboot" checkbox in Odin. I don't know about rebooting back to bootloader. My instructions were to go straight from Odin to recovery mode. In practice, for me, this meant hovering over the tablet as Odin finished. When the tablet started to reboot, I mashed the buttons to force it to recovery. If it did not reboot automatically, I triggered a reboot with the Power button. If I saw the usual Android startup screen, I let it finish booting, because I'm queasy about interrupting something like that. Then I started over: run Odin, try to boot to recovery.

Once in recovery, you are supposed to wipe data / factory reset.

Then you have to struggle to reboot, again starting by mashing the buttons for recovery, but this time you need to let go of the buttons after the tablet knows it's going to recovery, but before Magisk wakes up. This took me a dozen tries. If you read this thread, and maybe a related thread with T295 in its name, I think you will find a clue about which visual cue is your signal to let go of the buttons. Pay particular attention to advice from @gcrutchr and @Talich52.

I don't know if that particular error message is a result of failing to go straight from Odin to recovery. I suspect it is not, because I remember getting a normal Android boot in that case. It was not what I wanted, but it was still a boot.

If anything, I remember "SECURE CHECK FAIL" being a message on the tablet when Odin finished.

Also, I would not unpack image files. Try letting Magisk patch the original AP.tar.

If you respond, identify the "originals". If you have allowed your tablet to update past some critical version, then your bootloader will not tolerate modified software. Again, read the two threads.

Edit:

I lose track of which thread I am in. Other threads you should check are:

TWRP for SM-T290 & SM-T295

root for SM-T290

(Note: I am not advising you to install TWRP. I am advising you to read the thread for clues about which bootloader versions make it impossible to install Magisk.)
[Samsung Galaxy Tab A series Guides, News, & Discus] vidtek:
@J Michael, many thanks for your detailed reply. The version of the files used are for the T290XXS3ATF1 firmware.

My whole reason for requiring root is to enable the tablet to be used in my vehicle as a permanent sat-nav as the Nissan "new updated map cards (at a cool £120)" are at least 5 years out of date. I do not understand Google's reasoning in disallowing a boot when power applied facility, it makes no sense and creates a whole lot of trouble for their user base.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
I suppose TWRP is not required for your tasks, but only Root-rights are needed. In this case, just download the attached file, unpack to tar, select in ODIN as AP and flash. Once downloaded, install the Magisk.apk app version 25.2

Good luck!

P.S. if necessary, TWRP can be installed after rooting ...
[Samsung Galaxy Tab A series Guides, News, & Discus] vidtek:
Talich52- Many thanks for your input, I'll give it a go and report back here.

There are only 2 apps required to run on this device, Drive Recorder (a dashcam app-just really good at what it does) and Sygic navigation. The Drive Recorder app has settings to activate itself on boot, record in the background and automatically run Sygic, it is just the boot on power up that I need for complete automation.

[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Was something wrong with the Magisk-patched file @vidtek posted?

I know we've had people ask someone else to patch a file for them, but that did not seem to be the case here. I didn't understand why he posted the file, but he had already patched it.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
I can’t help with working with these applications, since I haven’t used them. If the programs are patched and only Root rights are required, then solve this issue.
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
There is an app on Google Play that claims it will autostart apps on boot. Have you seen it?
[Samsung Galaxy Tab A series Guides, News, & Discus] vidtek:
Yes, I previously used tasker for that on my previous tablet that was stolen.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
There is a recovery file for some reason that does not need to be patched by Magisk for T290 / T295. It is enough to patch the boot.img kernel and the vbmeta.img file, the kernel size is the same, but the vbmeta file has a different size than in my archive. Perhaps that is why an error was received when installing TWRP. Either only TWRP was installed, and the vbmeta file was original and gave an error ...

P.S. In the original (in the firmware), the files are in the form of lz4, which does not need to be unpacked - this is perfectly done by Magisk with a patch :)
[Samsung Galaxy Tab A series Guides, News, & Discus] vidtek:
I spent another 2 days on this and have finally given up.

No matter what buttons I "mash" on reboot, I always get the blue screen with the red banner telling me "Secure check fail : boot.img"

[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Flash the attached file and your torment will end, then you can easily get Root rights. This is an android 9 bootloader, android 10 and 11 will work with it, and most importantly there is no restriction on installing custom files :)

Talich - thank you for this, it worked and rooted. However the boot loader remained unlocked and required me to press the power key before the tablet would start. So I attempted to re-lock the bootloader and now I am stuck with a bricked device. I am unable to get it out of bootloader mode.

This is truly a real headache I am giving up and throwing it into the recycle bin.
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
For the record, I do not believe you had to press the power key before the tablet would start. (I assume you mean you pressed the power key until the tablet started to boot, then got the nag screen warning that your device had been modified. The message says press the power key to continue to boot. If you are patient, it eventually continues to boot without you pressing the power key.)

If you can get to download mode, flash the original, stock, unmodified ROM. Then start over: unlock bootloader, flash modified ROM. Just don't relock the bootloader.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
You are just not patient. You can briefly press the power button, or just wait a few seconds and the device will continue to boot. This screen is just a warning about an unlocked bootloader, and this screen cannot be excluded on our model.

Now flash the original stock firmware and repeat everything from unlocking the bootloader...

I waited over an hour with this screen after spending another hour previously trying all button combinations-always comes back to this one. This only happened by trying to remove oem unlock.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
The device with this screen is in the Downloading firmware mode and it is waiting for uploading files via ODIN, so nothing changes :)

You need to flash the stock firmware T290XXU3CVG3 or at least the stock kernel and vbmeta. I will attach the file with them, try to flash it first by selecting the AP window. If the problem persists, then flash the full firmware T290XXU3CVG3.

Talich and Michael - Thanks once again both of you for your patience with this old fart. I was able to do as you said Talich although the Odin window said fail. It will now boot normally when disconnected from the power supply.

With my new root status I was finally able to modify the playlpm file and now when the usb power supply is connected it starts to boot but now it gets stuck on this screen attached and won't go any further. I have to manually press the power button until it shuts down, disconnect from the psu and then press the power button again before it will boot normally. This is the playlpm file I placed in /system/bin:

#!/system/bin/sh
/system/bin/reboot

Any ideas? Thanks Tony.
