I am new to custom ROM. After I unlocked my bootloader, I am installing the xiaomi.eu ROM. But, I have seen that installation using fastboot will prohibit you from updating using OTA. I am not sure though. Is it better to install using TWRP or fastboot. If TWRP is better, how do you install it. And if I install using fastboot, do I have to manually update it using the computer everytime an update comes through?
