Hello everyone, this is a guide on how to flash new fresh fimware on your galaxy A12. This will help with issues like soft bricks, recovery errors, rom crashing, etc. This guide also might help with oem unlocking not showing in settings app, downgradeing to android 10 should work and fix the issue.​

This is not a guide for Heimdall but rather for odin.

Make sure you have followed my guide on how to unlock the bootloader before preceding to this guide, if you plan on installing magisk after.

Wait, I'm having this issue. After installing a Magisk module, my phone boot looped and I had to flash the firmware, and now the baseband and IMEI are gone and it randomly boot loops. I'm trying this guide now, but let me know if there's another solution.

Update: This guide fixed the issue. Now my phone works perfectly now :)
