The screen appears after booting into TWRP and trying to format memory:
I was trying to flash a custom ROM using TWRP recovery but it's showing Unable to mount storage & Failed to mount '/data' (Invalid argument).
I tried several methods like formatting memory but it's also not happening. It's showing Unable to format to remove encryption. Also tried to change the file format but nothing helped me. Now whenever I switch my phone on it automatically boot up into TWRP recovery mode. I tried this method and almost every method possible but nothing helped.
I'm using Moto E4 Plus (nicklaus).
