Hey, why the realme devices are not yet in the /e/ OS list.
It will be great.
I’m eagerly waiting for the /e/ OS, the privacy nowadays matters most.
Btw I’m new in this e-community
I think it would be very,very difficult for you to flash eOS (if it will be available sometimes) When you don’t know what a custom recovery.
For flashing a rom or a GSi you will need
an unlocked bootloader
a custom recovery like TWRP or OrangeFox
a stock firmware to go back to stock if something fails
