    Didn’t work, regrettably..

    I do have a Xiaomi Redmi Note 8T, TWRP or Orange Fox installed, rooted with Magisk v25.2
    When I try to set the property with the command:
    setprop sys.usb.config diag,adb
    I get the response:
    Failed to set property ‘sys.usb.config’ to ‘diag,adb’. See dmesg for error reason.
    dmesg: klogctl: Permission denied.

    And that’s it. No COMport showing in device manager…
