Mi 9t factory reset enquiry

Hello… I wanted to update my mi9t device for the next update which is going to be miui 12 that’ll be launch around this month (June) and I want to factory reset this device after the update. Can I still get this ratio launcher back after I factory reset my device or do I need to reapply the invitation code request? Please assist me. Thank you

You can reset your code using members.blloc.com
Of course, after you reset your device.
