Downgrade from OneUI Core 5 to OneUI Core 3.1 (Binary 5 to Binary 2)

[LadyD555]

Hi. I already know downgrading from Binary 5 to Binary 4 older is not a thing. But is there any alternative way for me to install Android 11 on my phone? Or it's stuck at Android 13/12 forever? Thanks for the replies.

No you not. Risky and can permanently damage your phone system, becomes useless.

Hello LadyD555,

Thanks for your inquiry, here.

It is not possible to downgrade from one version to the previous version once it is updated. Please note that the flashing of the device may cause misbehavior of the device and it voids the Samsung warranty. Samsung always recommends to keep the device up to date to get a better experience.
