I got one.... (A Redmi Note 9 Pro)....
It does have a smashed (but working screen). Waited the 168 hours to unlock, downgraded to the correct ROM as pointed out on the UT devices page.
Just installed Focal (stable) and charging the device ready to test.
Just posted to pint out I used Windows 11 and installed (was expecting the FastbootD problem) without a hitch (and no, not a Windows fan, but I paid for the licence so I am going to use it... )
Thank you for let us know. Hope you enjoy the experience on RM9P. Widi support will be available very soon (PR is waiting to be accepted). Let me know if you find any issues with the port.
Have a great day!
