vbmeta.img is a secure check against installing non-Samsung software. You need to disable it to install TWRP. Ignore error as long as TWRP installs.

You are on bootloader v4. You cannot root device. Also, you cannot go down to V3.

You are on bootloader v4. You cannot root device. Also, you cannot go down to V3.

how do you know what version of bootloader you have?

 

[gcrutchr]

how do you know what version of bootloader you have?

Ex: T295CZCU4CUK5....5th character from right = 4 = v4 bootloader

 

[Yxles]

Ex: T295CZCU4CUK5....5th character from right = 4 = v4 bootloader

So my Baseband version is T295XXU4CUK4 meaning I have a V4 Bootloader?

 

[gcrutchr]

So my Baseband version is T295XXU4CUK4 meaning I have a V4 Bootloader?

Yes. You cannot go back to V3 bootloader, and cannot install twrp

 

[Yxles]

Yes. You cannot go back to V3 bootloader, and cannot install twrp

Oh F, well that's just sad

 

[Grippingly]

Is there no any way to root u4? I have been searching ways to root u4 but nothing worked. Or is there any modified stock rom of this tablet? Its just so slow.

Sh...
I was nervous.
I've flashed the AP of step 4 of the instructions.
Then Odin and the Download Mode started hanging.
Nothing went in.
I've rebooted the Tab by pushing the Per and the Vol +.
Now this : ...

Is there anything, I can do, wright now?
I hardly can't power it off.

 

[JonnyBoy1984]

Sh...
I was ner...

Here I am again.
Suddenly it was so easy.

I've tried so much options, but I rember, I hope this has been the truth,:

I've cabled in the phone.
I've pushed Vol+ and Vol- together.
And than I've pushed the Pwr-button.

Than there comes the questions and options:
1) if unlock, push "long press" Vol up
2) if you wanna load the bootloader, push Vol+
3) if cancel push Vol-

It's been something like this.





Next try,

I see people still trying to patch files to get root.

If you flash the TWRP posted by @Talich52, with reboot unchecked you can install Magisk from TWRP.

Tested on T295XXU3BUC3 ROM (Android 10)

PREREQUISITES:

Bootloader unlocked - search forums.xda-developers for instructions how to do this.

OEM unlock on. In Settings/developer options, OEM Unlock slider should be to the right.

INSTRUCTIONS:

1. If prerequisites met: install Android 9 bootloader through ODIN (See attachement: Unzip BL*.zip FIRST)
If on Android 9, go to step 3.

2. Reboot to system

3. Go into download mode.

4. Open ODIN and in the AP slot put TWRP (see attachment below) (Unzip FIRST)

5. Uncheck auto reboot

6. Flash TWRP

7. Press vol dn + pwr keys.

8: When screen goes blank, press vol up + pwr keys.

9. Keep holding down both keys after reboot.

10. Tablet will reboot again.

11. When Samsung logo appears stop pressing pwr key.

12. When bootloader msg appears, release vol up key, quickly press & release pwr key, and quickly press & hold vol up key until in TWRP.

13. Install Fix_vendor_9.0.zip or Fix_vendor_10.0.zip. (Based on installed OS)
See attached files.

14. Clear dalvik/cache if prompted

15. You will then format (NOT WIPE) data. Answer yes to the format prompt

16. Clear dalvik and cache.

17. Reboot back into recovery.

18. Install magisk - see attached

19. Reboot into system. System may reboot again - that's okay

20. Enjoy!!

To the Instructions:

1. I´ve got the SM-T295 with Android 11 on it. I've just today freshed the firmware up, with Odin and Frija. Should I also flash BL 9, like you have written?


Can somebody who did it right and it worked help by "From the pushing of the first Key 'til the loaded TWRP ?

It hardly doesn't work, by me.

Check your bootloader version. If it is 4, you cannot install TWRP, and you cannot downgrade bootloader.
Ex: SM-T295CZCU4CVF2
The bold number is the bootloader version

 

[JonnyBoy1984]

Yes, I've finally flashed it to 4, I didn't knew it before .

 

[T3g4n]

It's annoying for Samsung to do this. Why won't they just let us downgrade?! I've been trying this for days for nothing. Thanks, Samsung.

Edit: Is there no way to change the version number in the code and make it think that it's upgrading but it's actually downgrading?
