You can't downgrade once you've upgraded

wouldnt there be a way through twrp or brom mode?

Nope you can try brom mode but i dont trust if works

If you buy a samsung device depending of the device (like this A12 and the MTK imei bug) is not a good idea to upgrade

That's samsung for you, once you've upgraded Binary version there's no going back.
As for the brom mode, samsung has locked their phones out of that mode. I don't know if accessing it through access points works but you could try to see if it can help

I tryed to downgrade via TWRP flashing baseband and BL

Now my A12 is DEAD and i dont had a box to repair it (after flash i see the security error screen and flashed again the Binary 3 BL once odin tell me passed the phone doesn't booted again)

I just wanted to get the imei working because the firmware on the binary 3 (11 and 12) android system uses all my ram memory trying to get the signal working

F*** *** Samsung and mediatek next time i bought an exynos or qualcomm variant

The last rom that i used on my A12 was pixel experience and worked perfectly on binary 3 android 11 based firmare (A125MUBUS3BVF1) just installed TWRP with nulled vbmeta flashed the image as system (not as super) and wiped the data (not advanced wipe) rebooted and the gsi was booted (only bugs mentionated on the thread and the touch bug)

i can access brom mode if that helps

How'd you do it?
Technically since I've always known that I can't access brom on my samsung I've never tried to understand what you can do with it.
