I have a Mi Max with the latest developer ROM (7.9.15) with locked bootloader.If I unlock bootloader,OTA updates won't work any more.I want to flash TWRP and I have some questions.
1)If I unlock bootloader and flash TWRP,can I download manually and do the update through the updater?
2)If I unlock bootloader and flash TWRP,can I download manually and do the update through the TWRP?
3)If,after flashing TWRP,choose to lock the bootloader,will TWRP work fine and will I have OTA updates?

Will TWRP work fine if I lock bootloader after flashing the recovery?Also,I have read that OTA updates aren't working with unlock Bootloader.
