Please someone can give me a backup of persist and persistent partition,

i format by accident now i got bootloop

T295 to get partitions at twrp

adb shel command

adb shell

dd if=/dev/block/mmcblk0p48 of=/sdcard/mmcblk0p48

dd if=/dev/block/mmcblk0p61 of=/sdcard/mmcblk0p61

please someone help, i think t290 would fix my tablet too.

thanks since now!

EDIT

i was able to make it boot

i deleted the command here to prevent anyone to erase they persist.

and its booted.

so if someone using google someday need this solution, use it.

be in the light

but no wifi and bluetooth

please someone provide a partition dump....
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Here are the files you need from the T295 tablet in a zip archive:
[Samsung Galaxy Tab A series Guides, News, & Discus] jwagnervaz:
thanks, you are the best !!! i will flash and report, thanks, thanks, god bless you!

edit

i flashed only persist mmcblk0p48

wich contains wifi scripts WCNSS_qcom_wlan_nv.bin etc...

Talich52 You are the best, thank you so so much for your help and good well.

if enyone on the future needs

Persistent mmcblk0p61 its safe to erase cause its the frp partition, wich contains screen lock settings, but persist its not safe to erase cause it contains wifi, bluetooh and sensors crucial files.

Hi there! I'm currently on T295XXU3BTI3 (Android 10) and have already unlocked the bootloader. I have already went back and forth through the thread but I'm still confused what step to take. help?
[Samsung Galaxy Tab A series Guides, News, & Discus] macranjoh:
okay, nevermind. this worked for me!
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Here is the zip file for rooting this firmware ...
[Samsung Galaxy Tab A series Guides, News, & Discus] macranjoh:
Yes thank you so much! I rooted my tablet solely for changing the region from XID, to XEV (the default CSC), then to XTC. I flashed the XXU3BTI3, the A9 BL and the root AP. then I set up the Magisk, changed the system files to XTC and did a reboot. After reconfiguring to XTC, I had it updated through Samsung smart switch and re locked the bootloader. Everything went smoothly!
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Yeah! Everything could be done much easier ;)

Install the Google Phone or True Phone application from the market, dial the code * # * # 27262826 # * # *, select the XTC region and press INSTALL. However, changing the region with data reset, without data reset, can be changed with the Samkey program, but this is a paid program ...

P.S. you can't go anywhere immediately from the XID region, since this is the only region, first flash the multi-regional firmware with the desired region ...

Better Android 9 or Android 10 to root? Which firmware is better and faster for this device (SM-T295)?

Are there any problems with knox for downgrade or root?
[Samsung Galaxy Tab A series Guides, News, & Discus] temporarium:
I stayed on 9 and works well. Never bothered upgrading to 10 on this tablet.

Forget about knox. It's triggered as soon as you unlock the bootloader and (to my knowledge) can't be reset. It's just there to give one a false sense of security anyway 😉. I usually disable all knox stuff once rooted.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
To root 10 android, you need to install the bootloader from the previous firmware 9 android, and then the rooting itself is the same - either patch the kernel and flash, or install TWRP and root the device from it ... The TWRP option is easier, but there is some difficulty in entering TWRP after it installation ...

On this KNOX device, cropped ...

In particular, there is no KNOX counter, that is, you can root the device, and then flash the stock firmware and there will be no traces ...

There is no KNOX flag as such 0x0 and 0x1 ...

Here find the SM-T295 model: https://www.samsungknox.com/en/knox-platform/supported-devices/2.5+

Our model does not support KNOX function ...

There is really a KNOX Guard application in the system, but if you Disable or Remove it, the device will be locked ...

It is not KNOX that prohibits downgrading the firmware version, but the bootloader. The version of the bootloader cannot be downgraded. From the 10th android you can return to the 9th android, since the version of the bootloader is 3 both there and there, but below you will not be able to install the firmware with versions 2 and 1 of the bootloader ...
[Samsung Galaxy Tab A series Guides, News, & Discus] quassars:
so sorry before ...

im kinda confused now .. haha, there are many files updated start from post #1 til last ..

should i use step on post #1 or i can just flash via Odin using bootloader file and rooted file ??

or anyone can make step by step how to do it .. on android 10 ??

my version is T295XXU3BTI3

very appreciate it .. this is my first time root with magisk ..

thanks anyway
[Samsung Galaxy Tab A series Guides, News, & Discus] quassars:
is this the simple step ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
1) unlock bootloader 2) flash 2 files through ODIN by selecting bootloader file aboot_vk_T295XXS3ATB2.tar as part of BL and root file as part of AP Root_T295XXU3BTI3_M20.4.tar ... 3) After rebooting the device, install the Magisk Manager file to manage Root rights ... That's it, use it :)
[Samsung Galaxy Tab A series Guides, News, & Discus] quassars:
failed .. unsupport dev ..

anything wrong ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
It would be nice to have screenshots and an ODIN error log.

The Root_T295XXU3BTI3_M20.4.tar.zip file must be unpacked to a tar file and then selected as part of the AP.

Sew the bootloader file first, and then the Root file, it will be clearer where the error is ...

P.S. Are you sure you have the SM-T295 model?
[Samsung Galaxy Tab A series Guides, News, & Discus] quassars:
yes .. this is SM-T295 model
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Clear... You are using ODIN version 3.12.05, but you need version 3.13 and higher, which work with lz4 files
[Samsung Galaxy Tab A series Guides, News, & Discus] quassars:
Amazing .. my phone is rooted now ...

thanks for your help @Talich52

first i found higher version of odin (3.14.1) but it failed

so i came back with version 3.13.1 then rooted ...

God bless ... thanks very much

last question ... is it safe if i install xposed or flash twrp ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
There is no experience on xposed ...

TWRP can be installed in different ways, including the Flashify program

from the market, if the img file or via ODIN, if the tar version. But to access TWRP memory, you will need to do format data (no wipe data) and install the Fix_vendor_10,0.zip patch ...
[Samsung Galaxy Tab A series Guides, News, & Discus] mysterionTM:
Can someone link me files needed to root this firmware?

T295XXS3ATB4 (last Android 9)
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
It is enough to unlock the bootloader and flash the attached file, having previously unpacked it to a tar file ... There will be Root rights and you can use them :) If you wish, you can install TWRP later ... Or, alternatively, start by installing TWRP and root from it ...
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
For rooting, flash attached files via ODIN as part of BL & AP. Pre-decompress zip file archives to tar files. The bootloader must be unlocked beforehand ...

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

There's a LONG while I don't do ROOT stuff. TBH it's more than 10 years

I have one SM-T295 from Brazil (info below), and I would like to know if I can root it.

My main reason to root it is to patch the device's cache to the SD card and have more space for apps (32GB is just too low).

I would like to know:

- Is my device rootable?

- Can I keep using Play Store after root?

- Is there a way to expand device storage without the root?

- Can I root using a Macbook?

Thanks all!
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Google "adoptable storage". I think it causes Android to use your SD card as extra storage. You can't use the SD card for anything else. I don't know how good a job they do of keeping your device usable if you remove the SD card.
[Samsung Galaxy Tab A series Guides, News, & Discus] chapoletada:
It seems that the lovely Samsung removed this option 😭
[Samsung Galaxy Tab A series Guides, News, & Discus] Joshua 80:
Guys finally I found out a easy method for rooting sm-t295 without ap. Or Odin software or a computer. It worked 100%

Step 1: make sure you've installed twrp menu before you go under this procedure

Step 2: download magisk apk and install it.

Step 3 now after installing the apk make sure you rename that magisk apk file to zip format.

Step 3: simple! Go to recovery (twrp) menu and then install magisk zip(the one you convert from apk to zip file) and it's done.

Step 4: sucess! You can check with root check apk also

For me it worked. Let me know if it's working for you all guys

Cheers

hi everyone, and thanks for all the work...

i m on Android 9 Update 1 (XXU1ASH7)

can i go with your file???

you say put the TWRP file in Odin/AP but i didnt find it in your attachements.

Hello people. It's been a while since I rooted a phone. I have a tablet galaxy tab a 8 inch 2019 running Android 10. Tried to follow instructions at the first page but I can't do it. Tried also to flash android 9 in case that was the problem but also failed. Any advice would be appreciated. I read all pages and I got even more confused 😕
[Samsung Galaxy Tab A series Guides, News, & Discus] Viggen66:
Salvator64

It seems Samsung insert a new protection to its tablet, if you change anything from the stock firmware, you only get black screen nothing more, albeit the tablet is working in the background.
[Samsung Galaxy Tab A series Guides, News, & Discus] Salvator64:
Sp nothing to be done to root it right?
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Tell us what firmware came on your tablet. Also what firmware you downloaded as "stock", and what firmware you downloaded as Android 9.

When you say "failed", do you mean you flash something and the tablet no longer boots? Or boots, but Magisk not installed? Or no sign that flashing changes anything?
[Samsung Galaxy Tab A series Guides, News, & Discus] NEwguy0101:
I also have the same problem this happened after I flashed the latest firmware T295XXU4BUD4. Now I cant flash android 9 bootloader and when I tried downgrading it won't allow me to. Can anyone pls help me with this I will send the files if required.
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
You cannot downgrade Samsung bootloaders
[Samsung Galaxy Tab A series Guides, News, & Discus] Cpt.mactavish:
I'm currently now on T295XXU4BUD3.....is there any way to root this now??

@gcrutchr @Talich52 sir
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
If the current bootloader version is already 4, then there is no solution. : (

But if someone has not yet upgraded to UD3 or UD4 ,they can do it via ODIN, using the attached bootloader file with version 3 and then get Root rights :)
[Samsung Galaxy Tab A series Guides, News, & Discus] Cpt.mactavish:
I'm regretting this update...is there any chance in future to get root in this damn U4..
[Samsung Galaxy Tab A series Guides, News, & Discus] PsyAnarchy:
Somehow my Tablet doesn't like things to be flashed other than the stock ROM. Maybe a little too shy because the It says Secure Boot Failed: boot.img then "security error this phone has been flashed with unauthorized software and is locked" I wish if there was a way to bypass this thing in some way.
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Hi All,

I just got a new Samsung TAB A 8" (4G) SM-T295, and I would like to root. Unfortunately, my firmware is T295XXS3ATB4 and I don’t find the file and a clear tutorial to root with TWRP & Magisk.

Can someone help me?

Thank you very much.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
This is Android 9 firmware which is easily rooted :)

1) unlock bootloader

2) flash the attached file

3) install the current version of Magisk Manager and update the current Root-rights from it

Recovery TWRP can be installed through the Flashify application ...

P.S. unpack the file to tar, select as part of AP in ODIN and flash ...
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Sorry I made a mistake, my firmware is T295XXS3ATB2. ATB4 is The VBMeta I tried unsuccessfully. I searched for the ATB4 firmware (French), but I didn't find.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Ok, here's the file you need :)

If you install a root file from another firmware, then Wi-Fi will not work, it seems there is a connection between the kernel and the system ...

P.S.Firmwares for XEF France region:

https://samfrew.com/model/SM-T295/region/XEF/

This is an OXM multi-region, there is no separate firmware for France.
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Many thanks Talich52. I'll try the VBmeta ATB2 next week and I'll report here the result. I'll download ATB4 as we never know...

Do you thing TWRP 3.40.1 is the right version or is there a better version for my device as my preceding action were unsuccessfully, but I am not able to determine if it is TWRP or the VBmeta story which is the cause of the trouble?

Edit:

I have a doubt, as I am looking if I have all that is necessary to root, I saw that my Base band is T295XXS3ATB2 and my Version Number is T295XXS3ATB4 (see screen capture enclosed).

So, I am no longer sure of what file I have to use ?

Any advice, please?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
T295XXS3ATB2 this is the modem version.

T295XXS3ATB4 this is the firmware of the device :)

So you need a file for firmware T295XXS3ATB4,

It is posted in the post above ...
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
I have been using this version of TWRP 3.4.0.1 from the respected mehanik6

since its appearance, everything suits me, so I'm not looking for other options ...
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Thank you for your help.

It worked very easily.

What I did, as you instructed me:

I had already unlocked the bootloader,

I flashed the VBmeta ATB4 with Odin 3.13.1 and I was a little anxious as Odin didn't detect an error, but on the device I got a red message "Security failed: VBmeta". So nothing seemed bad: I tested starting in download, recovery (the original one) and, of course, in normal way. I decided to continue.

I picked TWRP 3.40.1 (by mehanik6) file up and flashed with Odin. It seems to work well as I just tested backup and file explorer, but all seems OK. I just have a problem as every time I start TWRP, the language is unknown but in Cyrillic as I don't understand anything. I have to find and set in French or English.

I installed the v23 Magisk APK and with some trials and errors, it finally worked.

After that I tested and my device is rooted.

Next days I'll be very busy, so I won't have time to intensively test me tablet, if I encountered any trouble, I'll report.

Bye for now.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Yes, in TWRP, the default language is Russian, since it was done in Russia. After starting TWRP, go to the Settings and select the desired language. Настройки - Select language - Установить язык.
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Thanks, but is it something to do to keep my own language for the next runs?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Well, after changing the language, it will remain, but when reinstalling TWRP it will again be the default, that is, Russian ... You can try to unload (save) the recovery after changing the language, perhaps during the subsequent installation it will be ...

P.S. No, it didn't work out that way, but I found a solution :) Before installing TWRP, you need to copy the TWRP folder with the settings file to the internal memory of the device. I attached the folder in the archive ...

The language is English, but after changing the language to your own, you can save the TWRP folder with the changed settings file ...
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
I'll try that, English is very well for.

But for now, I experienced a new trouble when I want to made a full Nandroid backup from TWRP: boot, cache, vendor, image , vendor image worked very well, while at the beginning of data partition backup it stopped with the error message: "processus createFork()finishe with ERROR: 255".

Nothing interesting in the log file, just one line containing the name of the file file.

Unable to go ahead. Any idea ?

Edit: Sorry there is a log file, but with a lot of things, what do I have to look for ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
I won't tell you about working with TWRP, I'm not a programmer and rarely use TWRP, usually to root the device, and I don't see the point in TWRP backups, since I often change the firmware, and I save the data to the memory card with the Samsung Smart Switch Mobile application and make a Titanium backup ... When restoring, I first restore all applications and many SSSM data and then purely Titaniumom data. This is the best variant :)

P.S. There are other alternative custom recoveries ...
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Thank you.

I suspected a data error, But I tried to backup data only, and then, I get the error:

"Can not create '/data/media/0/TWRP' folder (Required key not available)). Failed to make backup folder."

So, there is another reason.

I need help as I am now blocked.
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Does that error come from using TWRP to make a backup?

Where did TWRP put the other backup files?

If you are rooted, you could make a tar of /data. When I did it I excluded /data/media. I wrote the tar file directly to an external SD card.
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Yes, it comes from TWRP started from recovery mode.

I just tried to backup all partitions except Data, and all worked well. I also tried Data only and I got the "processus createFork()finishe with ERROR: 255" message.

Do you have an idea ?
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Could Data be encrypted ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
The data section is initially encrypted! Therefore, in order for TWRP to have full access to the data section, you need to install the Fix_vendor patch from TWRP for your version of android and execute format data - yes (no wipe data).

The patch will disable encryption, and format data will decrypt the memory ...
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Thanks, I'll save all my apps and parameters with Titanium and format with TWRP. THen I'll restore from Titanium. I think doing that on Saturday.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Unfortunately, Titanium does not restore applications well, so I restore them from Smart Switch Mobile from a memory card, and then I restore only data from Titanium.

P.S. and it's time to install 11 android, I installed the firmware for China (part of AP & HOME_CSC), since for the XEV & SER regions so far there is only an over-the-air update, there is no full firmware for ODIN.
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
I did it, now I can see all the files with the TWRP file explorer, so it seems that the data partition is no longer encrypted.

Unfortunately, when I try to backup Data with TWRP, I always get the "fork error 255".

I have to say that I don't know what I can do now I am really lost.

Can someone help me ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Try another version of TWRP, there are references in this and related topics ...
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Do you think there is a link between the fork trouble and the recovery image ?

It seems that TWRP himself encountered a problem.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
I have already said that I am not a programmer, just a user with extensive experience ...

Perhaps the problem is in TWRP itself, but only the developer could say something by examining the recovery log ...
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
I don't know where to find a complete version of TWRP compatible with my SM-T295. I didn't see any version for these devices.

I went to 4PDA, but unfortunately a am not able to understand Russian.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Above in the post I posted Skyhawk-recovery, have you tried this option?

Unfortunately, there is no official TWRP ...
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Hmm ... I don't know English, but I use the Chrome browser, which translates everything,

as well as a google translator to English to translate what I wrote in my native language ...

But there is no more information on 4PDA than on the xda forum. And access to 4PDA.ru is closed, use the version of the forum 4PDA.to
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Many thanks, Talich52. Today, I have redone all the work from zero, and it is exactly the same.

I will try tomorrow.
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Hi,

I tried with the SkyHawk recovery, but is exactly the same result. There is something else, but I don't see. The only trouble I got was the red message when installed VBmeta telling "security violation...". I don't know I it has a relationship with the error 255 I experience.

Now I haven't any idea of how can I solve this problem.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Given an error when installing a file via ODIN? This is only a warning from the device's security system, the file itself is successfully flashed by ODIN and we see the PASS board.

Accordingly, just ignore this message ... :)
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Yes, I did. Odin successfully flashed it.

But now, I am stopped. Rooting has worked, but save (which is the main reason I root) doesn't work. I looked in several places, but no track of my trouble.
[Samsung Galaxy Tab A series Guides, News, & Discus] VampiruX:
Can someone tell me if the backup function (data) work in Android 10 ? I am not a fan of Android 10, but I could upgrade it if was the fix to my problem.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Where do you backup? If on a memory card, then it must be in exFat format! If the card is 64Gb or more, then it is formatted by the device in exFat. If the card is 32Gb or less, then it is formatted in Fat32, which does not support files larger than 4 Gb. Maybe that's the problem ?!
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
On Android 9, 10 and 11, the same PIT file for this model, this means that the sections are the same and TWRP will work on Android 9, 10 and 11. Specifically, I use TWRP 3.4.0.1 for T295 and made a data backup to a 64Gb memory card successfully ...
