you can use patched magisk in https://xdaforums.com/redmi-k30-5g/development/recovery-lineageos-recovery-17-1-redmi-t4059879 to root device
Thanks for your ROM since I have been using it for a couple of days with no critical problem found. However,
1. Since 5G NSA falls under LTE, is it possible to make it displaying "NR" or something else to indicate that the phone is on 5G network? If impossible, is there any other ways to know whether the phone is on 5G or not?
2. Is there a working root solution for it?
Thank you for your time and effort
