Hello, no matter how hard I try, I can't install any ROM on Redmi note 9 pro :-( I have unlocked the bootlader and installed firmware global 11.0.7.0 and USB debugging enabled ... Do I have to have a sim card inserted during installation? I would like a simple firmware no ads ... I managed to install TWRP but after the restart my phone did not start up and ended in an error ... Can someone please help me with the installation of the EU version or custom rom? Thank you very much for your help ...
