Redmi note 5 usb problem

[Oskaris25]

Hello, I installed miui 11 using TWRP and the computer does not detect the usb but the phone is charging. I want to lock the bootloader but can't. The system works, but files cannot be sent and is unlocked, and some applications are not working.

Find option file transfer when connect, i guess
