Then i flashed a bad module from magisk that make my device very laggy.
So i decided to flash the rom again.
So i wipe cache, dalvic chache, system, data, internal storage.
But when i wanna flash it again, it always failed!
It says uneable to mount /system..
I move to twrp and select wipe, advanced wipe, system then repair or change file system and now my file system is ext4 is it correct? What should i do?
Please somebody help me
