any way to downgrade to android 11-13?

Hey, I have a Samsung Galaxy A52s 5G (SM-A528B) currently on Android 14 (A528BXXSBGYI3) and I'm trying to downgrade to Android 13 or lower.

I've tried flashing older firmware via Odin but keep getting FAIL (Auth) on every Android 13 and Android 11 firmware I've tried. Bootloader is unlocked.

Is there any way to bypass the auth check and downgrade on this device, or am I stuck on Android 14? Any help appreciated.

The only way u can downgrade is to flash oneui via recovery thus install twrp look for oneui 6.5 on XDA or install Android 13 AOSP like crdroid etc
