Is is the version with bootloader version 4? That currently won't support custom stuff, because Samsung disallowed it in the new bootloader and it can't be downgraded. You can still l reinstall the latest ROM, but I don't know whether this is your case. Check in Download mode what the bootloader version is and give it to me.
The truth is that I got lost in your explanation, I only understood the last thing, I think.Could you explain it a little more simply, for someone who is new to this?
There is a bootloader which makes the OS bookable, and the bootloader can be updated. On version 3 of the bootloader and lower, you can flash custom things like a custom recovery like TWRP. And now that you are on the latest One UI ROM, they updated the bootloader version. In version 4 of the bootloader, it is now impossible to flash those custom things. However, you might still be able to flash the stock ROM to get the stock recovery back.
Do I install the same ROM with which I had installed the twrp?.Do you think something will happen to it if I install this ROM. Will the errors it has be fixed?... but those errors are not because I updated the system, it is still the same with which I installed the twrp.
That won't work, the bootloader will stay at version 4 and there is currently nothing to get around it.Do I install the same ROM with which I had installed the twrp?.Do you think something will happen to it if I install this ROM. Will the errors it has be fixed?... but those errors are not because I updated the system, it is still the same with which I installed the twrp.

Unfortunately, you now can only stay on the stock ROM, and flash newer stock firmware with ODIN if needed.Then what do I do?
But how do I know if I have version 4 that you say I have?.suddenly it is not version 4 and it is a lower one.
Well, I am sure because of 2 reasons:
I will do that
I think so far I'm a little confused about the version 4 bootloader, about its advantages and disadvantages. You will not have a page where I can read about the bootloader version 4.
You don't give any details. I'll try to guess - the SM-T290 device is from the latest releases. They are characterized by either protection or the use of another display and when changing the bootloader to android 9, the screen turns black... There is no solution, except for replacing the device.
current bootloader version is T290XXU3CUF8. i'm getting black screen after flashing android 9 bootloader. i can build the whole twrp from scratch . but need some direction. is it impossible to deploy twrp on latest devices ??
i have built this recovery for this bootloader using dumprx tool. or can i downgrade the whole OS to android 9 and do the installation ??
Yes, you can install android 9, but as soon as the android 9 bootloader is flashed, the display will be black. And how to use it?
On this instance of the tablet, Root & TWRP cannot be installed
i there any way i can install GSI with blank recoveryOn this instance of the tablet, Root & TWRP cannot be installed
At the same time, in the stock version, the device is 100% functional...
Maybe boot into recovery with the keys, and maybe then get to know the things you need to press by watching TWRP screenshots to get to ADB sideload. From then, you can run commands on your OC connected over ADB to flash GSIs I think.
Here's a 3.7.0 build...
I'll have a release of my Nexus Stock custom ROM shortly. It's basically the same as what I've been releasing for the 10.1" version of this tablet over the past year. I'm basically just waiting for Samsung to post the latest kernel source.
