Is it still not possible for SM-T220 and SM-T225? Maybe there is a way to do and trick/bypass binary version via some kind of custom recovery? I'm kinda new to this topic would appreciate any informative responce! Thank You in advance!

very risky to try. for now bootloader was version 4 , Your BL must be v.1 if you want to downgrade firmware.

I know right, so there is absolutely no way to downgrade to android 11 with bootloader version 1 if I have bootloader version 2 or above and android 13?

Yes.
You'll need scatter firmware of old Android version and to be safe backup the original firmware.

If by scatter you mean software engineering and modifying original samsung firmware, then sadly, I'm not software engineer :/ Or is it just flashing old firmware via SP Flash Tool and thats it? Can You please provide us with step-to-step guide? I will really appreciate it

The simplest way, download qpst version of ROM (Vibe2.0 Android 4.4.4) and flash it by PC (QFIL utility).

Even if i had Whatsapp, WHY would i add you to my contacts? Is that the condition to use your share? Do you only share stuff with someone who adds you in Whatsapp???
I really dont understand this....

It works for my 32gB model Honor 7x. :good:
I also used stock recovery and flashed the mentioned files using fastboot command.
[I didnt try using the TWRP method as I had already flashed by recovery to stock before trying this rom]
the commands looked like this:
"fastboot flash system system.img"
"fastboot flash cust cust.img" and so on.
Hope this helps
Can you explain it clearly brooo.....please urgent broo..

I doubt it'll work, but I figured I'd ask: Has anyone tried this on the American model? (BND-L24) - I'm gonna test shortly, so I'll be able to confirm whether or not it works. If it does work, I doubt the bands will work properly, if at all, but I'll give it a shot.

I guess if you download the first ever android release for this phone from its official website and flash it via its stock recovery, you will be able to downgrade your phone to android Nougat.
Backup ur data before doing this. Coz it may delete your personal data.
NB: Do at your own risk. I have not done it. So cannot confirm if it works.
i can do it , tested

If your bootloader is unlocked, you might be able to downgrade using Odin.
Are you sure the Android version is the problem? What app are you trying to use, and are you rooted?

Depened on A13 Firmware version.
The last FW which you can drowngrade is "XXU1CWA2" both T220 and T225.
Ok, I checked the BIT on samfw and succeeded.
On my A13 I still had the version with the BIT at 1.
I had previously tested from an A13 with the BIT at 2 and it had gone into Soft Brick.
Thank you
