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.

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
