Ok i will see for the sd card but like i said even the internal storage is mounted but twrp see nothing is empty, is a problem here.

Can i ask your file boot_vbmeta_T290XXS3ATF1_Root_M20.4.tar.zip it is not necessary for me? I also got the Check Fail vbmeta in the download mode after twrp but i also read your answer in the previous page that it was normal and he had nothing more to do!

Boot_vbmeta_T290XXS3ATF1_Root_M20.4.tar.zip file

Laid out for rutting firmware 9 of the android T290XXS3ATF1, why do you need it?

By the way, try to get Root rights first, and then install TWRP, as described above in the message ...

You do not need to disable AutoReboot ... If you disable it, then after flashing the files, restart the device manually ...
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
Thank you thank you sir

It worked perfectly :)

Have root and TWRP and it was very easy to follow your instructions and get everything working so quickly.

No messing around with key sequences etc etc.

This is the only guide that everyone can follow and get root etc without any hassle ins, if they want root.

Two more questions

Same steps and files for Android 10?

Key sequence to get back into TWRP from shut down or reboot?
[Samsung Galaxy Tab A series Guides, News, & Discus] almararn:
Glad to see that you managed to root the SM-T290. Would anyone be willing to make a step by step guide for rooting this device, that has been updated to android 10, like most of them probably are?

I've rooted a few devices about 10 times (with step by step guides), but this thread is to big and messy for a guy with little experience to know where to start.

Or if anyone could tell me that after root, I would be able to extend RAM virtually with SD card, so that I can install the Samsung Smartthings app on this device, that requires more than 2GB of RAM.

Update

Had problem with flashing boot_vbmeta_T290XXS3ATF1_Root_M20.4.tar on Android 10 with Android 9 Bootloader but worked with flashing Root_T290XXU3BTG1_M20.4.tar file.

Wasn't able to backup tablet in TWRP to either Sdcard or external SD card.

Formatted Data partition but same we error.

Anyone else have this problem?
[Samsung Galaxy Tab A series Guides, News, & Discus] sevsman:
Try to mount and then unmount the data partition in the mount settings, before backing up.
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
Unmounted and remounted many times

Same error
[Samsung Galaxy Tab A series Guides, News, & Discus] sevsman:
You could try to backup all your stuff, wipe data with "yes" and then format the as card aswell.

You don't really need to Dona backup as the ROM is stock based and works/boots 100%.
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
Already formatted data with yes and same error.

Contents of my internal storage now :)
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
Formatted DATA partition again and then wiped data.

Able to Backup now

Have to restore my apps and settings and then do a full backup :)
[Samsung Galaxy Tab A series Guides, News, & Discus] sevsman:
You'd only formatted it before and not wiped with "yes" and that's why the storage was encrypted.

If you've not flashed the vendor fix whilst still on the stock ROM you may become encrypted again.

Flashing the fix is not needed with my ROM though as I've already removed FBE from it.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
We did the right thing,but not everything! You also need to install a patch to disable encryption.Patch for Android 9 and 10 in the message: https://xdaforums.com/showpost.php?p=83483981&postcount=123

---------- Post added at 11:00 AM ---------- Previous post was at 10:33 AM ----------

A common question is how to log in to TWRP or stock recovery if the bootloader is unlocked,which was not easy.I will describe a good reliable method.

1)We send the device to reboot after flashing the TWRP file or during use.

2)A warning screen appears about the unlocked bootloader - briefly press the Power button.

3)press and hold 2 buttons - Volume Up and Power.We hold up to the warning screen about the unlocked bootloader.

4)briefly press the Power button.

5)press and hold the Volume Up button until you enter the recovery mode :)
[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
I have exactly the same things! Twrp see many strange files that do not even exist in reality. The real files twrp do not find any.. However I do not have any errors message for now and is look mounted. About the encryption twrp do not asking me any password so I am not sure about this. Do you be able to fix this? How?
[Samsung Galaxy Tab A series Guides, News, & Discus] sevsman:
You need to wipe data and internal storage with "yes" because you booted before wiping and now all the files are encrypted.
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
You need to do the following:

1)to flash TWRP.

2)Upload in to TWRP.

3)Apply the patch to disable memory encryption for Android 9 or 10,attached...

4)Run from TWRP format data - yes (not wipe data)

Your Custom Rom

Had issue with TWRP Format Data after installing the the Vendor Fix Android 10

See screenshot

So in TWRP I rebooted back to TWRP, successfully Formatted DATA and then installed the Vendor Fix Android 10

Successfully installed Sevsman's custom rom and after restoring my apps and app data using Swift Backup, I rebooted back into TWRP and successfully backed up my custom rom.

Don't know if installing Vendor Fix Android 10 after Format Data does anything as your instructions were to flash the vendor file and then Format Data :)

Congratulations mate. I just need a 295 tester and then I'll release them both.
[Samsung Galaxy Tab A series Guides, News, & Discus] cossak2007:
Ok.

Not many developers for the T290 295 series.

Lot more for the 10.1 2019 tablets

Think many users of T290 295 tablets get frustrated with the rooting process and give up trying.

I'm an experienced rooter for many years on phones since the Google Nexus 5 came out but nothing like this on Samsung tablets.

Have given up many times and tried again over last six months and now am successfully rooted.

Never experienced such frustration in my life :laugh:

[Samsung Galaxy Tab A series Guides, News, & Discus] Max128:
Hi, thank you very much for having it that help you provided me and also the other guys here who helped me. It worked in the end with the files i am rooted.. My sd card I formatted them in fat32 and in exfat using the computer by windows 10 and even a specific application and twrp still did not see it. I then formatted the SD with android and then it worked in twrp. I never had this problem there on my other devices and i root my devices since my first phone since ten years.

I'm a little worried about how is it going with the next updates, i will probably do it with odin.. and do you think it will be possible soon to have twrp on the new bootloader? I'm talking about Android 11 in part, I'm assuming it will be released on this tablet!?

I'm going to assume it's normal that twrp doesn't save any settings? like the language .. for now i will stick with the stock rom , probably later i will try a treble rom , i will wait to see here how the rom treble will work on this device and the problem that comes with it.

I must say i prefer the operation of flashing from google and htc more than samsung.

I am ready now to test this tablet , look pretty good for now for those who have had it for somes months how do you like the tablet? what do you like the least?

By the way thanks for the website for the rom, the rom is good but lol yeah is really slow! is took my about 5h30 to download a rom! I have a gigabit connection, i do not remember the last time i have wait so much.

Thanks guys for the work and carry on!
[Samsung Galaxy Tab A series Guides, News, & Discus] Talich52:
It is better to format a memory card in the device where you will use it - in a smartphone, in a tablet ... And for Samsung devices, it is desirable to use a memory card from Samsung.

The current TWRP works on android 9 and 10, on 11 it should also work, since the sections do not change when the android version is changed, the same PIT file is the same for android 9 and 10.

TWRP creates its own folder where it saves its settings, and if there was no memory cleaning, then TWRP does not need to be configured every time ...

Downloading Roms Slow Speed

I have mostly downloaded roms etc on my desktop or laptop computer and then copied to my device using USB cable or wireless connections ..

Took me 30 secs to download rom and another 20 sec to copy to my SD card on the tablet.

Will try downloading the rom from my tablet and see how long it takes me as I am curious now :)

Prefer working on my Windows Desktop as I purchased a Samsung 32" TV 3 years ago and I can work on my computer and at same time watch TV in corner of screen to watch sports etc :)

Sandhook and congrats again on completion of your projects :)

---------- Post added at 06:06 PM ---------- Previous post was at 05:46 PM ----------

Not a Treble rom by any means.

It is Stock as original when phone was new or updated by manufacturer to newer version of Android but rooted and TWRP installed with encryption removed by different methods for each phone tablet manufacturer

Then stock rom can be backed and restored with TWRP

Sevsman has done that with his custom rom but in addition, removed unnecessary Samsung apps

Still stock rom with original Samsung system .

My Moto Z Oreo, I rooted and installed TWRP and to remove the Motorola encryption, I had to FORMAT Data (not wipe) in TWRP and rebooted phone to setup as normal but without encryption,.

Then after setting up everything the way I wanted with apps launcher etc, I rebooted back to TWRP and backed up my rom to phone external SD card for future use if necessary.

Hope I have made sense to you :)

No, this is a pre rooted android 10 ROM that is highly debloated but DOES include gapps.

If people don't want gapps they should either buy a non Google device or grab a GSI that's vanilla.

I have an iPad pro 2019 11".

I love this tablet. But, I am a die-hard Samsung geek!!

I have a NoteFE, Note 10, Note 10+. All are rooted. (Notes are Qualcomm devices)

But Samsung does not update the tablets very often. And, eventually, they stop updating.

I am an Apple iPadOS beta tester. No problems with betas, unlike Microsoft developer betas!!

I have had a few Samsung tablets. They are okay. I can root them, de-bloat them, and customize them. But, if I cannot get updates, what the point in having a Samsung tablet? If I change over to LineageOS, I lose a lot of functionality that I normally use. I have tried LineageOS on previous Samsung tablets and am not impressed. I have a very specific reason for owning a Samsung SM-T295 tablet. If updates are available, great!! If not, that's okay. Even if I could not root the T295, I would have still purchased it.

Oh well.. I have removed a little more of debloat apps.. considered safe to remove, I only deleted a few apps.. After the reboot the tablet remains stuck on the splash screen, can do nothing. So i flash AP in odin and root.. after this the tablet boot again but with a factory reset i have lost everythings.. I didn't even flash a CSC and of course no backup, I have never had this kind of problem removing apps from my other brands of device.. I will be more careful when deleting apps on this tablet.

Do not worry i will do a backup when i will finish this time. Yeah i will probably try it soon.. Can you send me the link?

Absolutely NOT for Android 10 and as mentioned , fewer tweaks and many do not work on our tablet..... eg .... no effect for Advanced Boot menu when pressing power button to reboot...still the same Shut Down and Reboot...no reboot menu for booting to Bootloader Recovery etc like I have and had on my phones.

Has worked great on Oreo 8.0 & 8.1 and Pie roms on the many Android phones I have owned.

Maybe its a Samsung thing or being a tablet as original developer of app hasn't supported GravityBox after Oreo .

Also app not on Play Store any more ... only the app unlocker for advances tweaks after purchasing.

Maybe there is another xposed module that has similar tweaks for Android 10.

Not going back to Android 9 to find out if and how it works on the tablet Pie version :)

I like to customize appearance and use tweaks to improve the functions of devices I have.
