No issues on my side.

---------- Post added at 01:45 AM ---------- Previous post was at 01:29 AM ----------

Go to DeviceCare in settings .

Check your internal storage as low storage will slow tablet down or cause apps to crash .

Check also how much memory you are using and how much left.

Did you PM and ask for custom stock rom link?

Problems you have now could be solved with the installation of the custom rom

You will then know if your issue is with the rom you are currently on.

TWRP backup your current first :svetius:

Why are you wondering about about adding ram using SD card without resolving your current issues first ?

Just curious :cowboy:
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
Yes I know , My internal storage is like that: 15gb used of 32gb, the most is using by the system, I have 3gb of apps I do not stock data on it I put in the SD card.

Yes I have pm for the rom yesterday but still no response.

Why I ask it? Because is probably what is happening, or some apps don't like to delete, what is your ram usage like? Maybe some others people can confirm this.
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
Don't have any lag when using this tablet.
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
I have small lags sometime not big and i think is when the things i have talking about above is happening.
[Samsung Galaxy Tab A series Guides, News, & Discus] sevsman:
It's 100% down to your debloat and absolutely nothing to do with available ram. Adding an SD card as adoptable storage is just storage and nothing to do with ram either.

[MENTION=3852065]sevsman[/MENTION] , [MENTION=4767829]cossak2007[/MENTION] I do not believe this twrp give me another problem again.. I am trying to make a backup for the first time on this device... boot,data,system.. i am trying to search on this, i have a error after the backup of the boot i got this:

createtarfork() process ended with error=255

EDIT: after this I do not have anymore the haptic feedback in the OS I only get vibration when I boot the tablet, in recovery and when I put in the vibrate mode but still no vibrate at all in the os except this. I do not find either how I can activate again. What twrp do again? Twrp never give me so much problem
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
I know personally that the first time I flashed TWRP and tried to TWRP backup, I received the same error you had.

I did a TWRP Format Data, not wipe data, and was then able to backup and restore.

Flash TWRP first and would tend to agree issues were result of your efforts to debloat and removed some vital component(s) of system.
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
[MENTION=4767829]cossak2007[/MENTION] Yes I will start again... lol , what app do you using for saving your apps and data apps? Normally I am using titanium backup pro but I have some problem with it since a while...
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
The error is caused by not having encryption disabled.

While in TWRP, use advanced, file manager

Look into /data/anr folder. See if it is encrypted. If yes, you need to 1st use fix_vendor.zip, then format data, clear cache/dalvik, then reboot into TWRP.

Check data/anr folder again. If not encrypted, you are good to go!
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
yes indeed, data/anr is still encrypted... But the internal storage is no more encrypted is work fine. I have already flashing the vendor fix and format data more than one time.

Don't understand this , It should be either that the device is encrypted completely or not at all.. At the moment i have a half encrypted device.. So weird...
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
Since I got the error above with twrp .. the haptic feedback in the OS is not working anymore, it's not hardware because it works in the boot, in twrp and when i put it in the vibrate mode. I just installed the full firmware again including the android 10 bootloader and still the same problem, pretty a big bug do you know how to force it?
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
Sorry, do not know how to fix it.

I do not use haptic feedback.

---------- Post added at 08:30 AM ---------- Previous post was at 08:27 AM ----------

Vendor is still in memory and encrypting /data

After installing fix_vendor, clear cache/dalvik, then reboot to recovery, then format data.
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
Yes i will try this when my problem will be fixed.

how did you be able to disable the haptic feedback? Because is enabled by default i think, but i do not see anywhere how to disable or activate in the settings. By haptic feedback i mean the vibration for the three softkeys and keyboard samsung...
[Samsung Galaxy Tab A series Guides, News, & Discus] gcrutchr:
I didn't disable haptic feedback. There is no option to do so.
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
I have ask you this because you have said you do not use the haptic feedback. I do not know why is stay disabled even after i installed the full firmware again, this was started after the twrp error.
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
Do you have the haptic feedback on the soft keys?
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
Work around.

For rooted and unrooted devices.

Found an app(s) for Samsung devices for haptic vibration on soft navigation keys on Play Store.

Older apps but works on this tablet.

Our tablet has haptic vibration settings for system keyboard keys but not for the navigation soft keys as far as I know.
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
Sevsman question... Are you still working on your custom rom with aroma install ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
Yeah! this is awesome! i have testing it and is work fine. I said I had the vibration the other day but I think I got mixed up with the keyboard. How did you have find this apps? i have seaching on google about a one hour and i do not find this apps. So.. Thanks you! I can confirm you this, We don't have any settings for the keyboard haptic as well for the keyboard of samsung ( I also did not find how to activate it in any ways) So i use the google keyboard for getting the haptic , google keyboard you have the settings for it
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:

Same problems here. I tried to flash the patched AP file (magisk patched .tar) together with BL, CP and HomeCSC files. It failed to flash and proceeded to go in a boot loop.

To get out of the boot loop, I used the combo key to get into recovery mode. From recovery mode I selected DL mode. Flashing stock ROM did not give any errors in ODIN for me.
[Samsung Galaxy Tab A series Guides, News, & Discus] Koerst:
I did figure that out too, but that's where I'm confused about the terminology. On ADB and Fastboot and on "recovery" mode (The one where you hold power and volume up), that screen is called "bootloader" mode. However, when I tap the volume up buttons when the unlocked bootloader message appears, it is called "Recovery". You also have called it "firmware" mode. This bootloader/recovery/firmware mode is different from the "download" mode. When I use the command "adb reboot download" in ADB and Fastboot it sends me to a blue screen with a USB symbol, which is what I tried to use to flash the things on Odin. When I use the command "adb reboot bootloader" or do what you instructed, it sends me to the black and white "Samsung Tab A" loading screen with a little area in the top left corner that has a bunch of lines that say things like "OEM Lock: Off". The screen doesn't change. So it's just a bit confusing for me because they are apparently two different things with many different names. Anyway, thanks for the help.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
I have been using the Samsung + 300K + Tool.exe program for a long time, I connect the running device to the computer and start this program, I click on the resistor with the left mouse button and the device restarts in ODIN mode :)

This is the same firmware mode (ODIN mode), but without service information in the upper left corner ...

P.S. In Recovery mode, the top line is yellow; Android Recovery :)

Below is a menu of several items, including Reboot to bootloader.

in Recovery mode, ODIN does not see the device and it is impossible to flash it ...

P.P.S. I uploaded the program in a zip archive, because otherwise the forum does not accept it, possibly considering it a virus ...

boot to bootloader

On mine, recovery mode has a line "boot to bootloader". That seems to be the Download Mode.

---------- Post added at 13:16 ---------- Previous post was at 12:50 ----------

What files did you (patch and) flash?

I haven't found anything on sammobile. samfrew has lots of zips, some with the right date (20190812 for me). I tried one -- patching the AP with Magisk Canary, downloading with Patched Odin -- and Odin says "failed", the tablet says SECURE CHECK FAIL: vbmeta.

I downloaded a second ZIP file from samfrew, but its contents are identical to those of the first, so I don't see any point in trying again.

I don't get a boot loop when Odin fails. In fact, if I'm not right on top of it when it fails, the tablet reboots to Android -- in spite of my having unchecked the Odin "auto reboot" option.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
All the same, custom files are not flashed ... if you delete vbmeta, then patched magisk files boot.img & recovery.img are also not flashed, and the device goes into reboot :(

Has anyone tried patching and flashing Magisk with the most recent (2020.1.10/20.3) version?

(I'm a bit wary of trying it myself, since I somehow managed to hard brick the last device I tried to root...)
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Tried all versions of Magisk, including the version CANARY 20.4 (20303) | 7.5.2 (272) (7).

But none of them work :(

And to restore the device,it is enough to flash the current firmware, or even 3 files are enough: boot;recovery;vbmeta, pulling them out of the AP part of the firmware ...

No one wants to deal with our device... :(
[Samsung Galaxy Tab A series Guides, News, & Discus] secretwolf98:
No, Samsung needs to release the source code for the SM-T290 before anyone can start developing for it.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
Yes, here you are right - on the previous T385 I received Root rights only on the kernel compiled by the respected ashyx from the source;)
[Samsung Galaxy Tab A series Guides, News, & Discus] J.Michael:
Please give more details.

What problem does this solve?

What is FRP unlock?

Why does it need to be skipped?

What is GTOWIFI_EUR_OPEN?

Do I have to extract the PIT file from the CHN firmware ZIP file?

Do I have to tell Odin to use the PIT file?

Do I have to check the Odin option to repartition?

Where is "Samsung FRP bypass"?

Do I have to relock the bootloader?

When (i.e., during which steps) is the bootloader supposed to be locked?

When do I unlock the bootloader?

Again, what does this accomplish? Do I end up with a rooted tablet? Do I end up being able to install Magisk?

I have root on my SM-T295 A8 tablet!!

Attached boot.tar file is for XXU2ASL3 only.

T295_Magisk-Boot.img.tar

Okay, after multiple failed attempts, I read about a method to root my T295. It did not work!! But, I decided to just use Magisk Manager on the boot.img file only. The resultant file would not flash - it will fail. The original boot.img file is 65,536K bytes. I had to take the Magisk modified boot.img and overlay it onto the original boot.ing file. Then the file would flash successfully. The first thing after booting was to check Magisk Manager. It showed I have Magisk 20.3 installed. So, I tested this with Root Explorer. I did have root!!

If you are going to try this, you need to unlock your boot loader, I think. I have not tried this with a locked bootloader.

I just rooted my SM-T290 with firmware version T290XXU2ASL3, using Magisk 20.3. It's been stable for a couple of days now. Here's a link to my patched Magiskmodpatched.tar file.

Problems included a lot of links that led me to the wrong firmware, an SL4 version that was a Kids ROM for the SM-T290. Another thing that caused problems was zipping the whole .tar archive back up with the patched boot.img, recovery.img, and vbmeta.img files plus all the original extraneous little lz4 files. It didn't root successfully until I simplified the patched AP file to contain just the 3 compressed image files.

Hi,

A new update is out and the device offers me the update in OTA... I also have downloaded the full rom on the website. I have stock rom with root with magisk. What is the best way for installing a update with the root ?

Also after the update the tablet will become encrypted again or not? If yes what you need to do
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
It will not be possible to update via OTA when the bootloader is unlocked, therefore, only by installing the full firmware via Smart Switch or via ODIN.

Yes, after the update, the memory will be encrypted again, since the firmware will be stock with a stock kernel, stock recovery and stock (without patch) vendor section.

I am doing the update like this:

I am flashing through ODIN the firmware with the HOME_CSC part. With the PASS display, I fold back the cable and carefully look at the display, how the device enters the recovery, installs the update, does the erasure and goes into reboot. First, a warning appears about the unlocked bootloader, I press any volume button and see the menu, where I select the Recovery item and briefly press Power. The device enters bootloader mode, I connect it to the computer and upload the TWRP file and the bootloader from the 9 android. From TWRP I install Fix_vendor and Magisk.zip and you can boot into the system ...

P.S.

If you do not allow the device to boot into the system immediately after installing the update (stock firmware), then the memory will remain encrypted, therefore this is the procedure described above ...

The rooting procedure is the same for the T295 & T290. The TWRP file is generally universal and works on Android 9 and 10, T290 / T295 models.

2: flash the abootvk file @Talich52 provided

3:reboot

4:boot to download mode

5:inside odin go to options, and untick "auto reboot"

6:flash the twrp file

7: dont reboot or shut down

8: after flashing twrp press and hold power + volume up

9:when it goes to the "this tablets bootloader is unlocked screen" (it comes up every boot if you have unlocked bootloader, which is needed for rooting)

press the power button once to dismiss the warning and press and hold power + volume up for two seconds then leave

10: you should be in twrp now

11:it is defaulted to russian language for some reason find the language button ( usually bottom right above the slide bar)

you can use google translate on other phone to check for it

12: now you can flash magisk that @gcrutchr provided in the post i mentioned above
