Impossible to flash TWRP

[matp75]

Hello, I am trying to install /e/ on my smartphone, but i am actually stuck.

I followed different thread but couldn't find response.
I managed to activate fastboot, and unlocked my phone; USB debogage is activated and EOM too.
My phone is actually on factory version - but i activated USB / EOM debogage again and i checked phone is unlocked.

I am trying to flash TRWP before flashing /e/ . But i can't flash TRWP. I got an error : ANDROID_PRODUCT_OUT not set
I read somewhere i need to downgrade to android 11, but i don't managed it .

My smartphone is a redmi note 9 pro ( " Joyeuse" ) MIUI 14.0.3 android 12 SKQ 1.211019.001
Thanks for reading me! Have a good day

@matp75 Really so hard to read the very 1st sticky thread in the Q & A thread, which is called "Installing a Custom Recovery"?
