Notes: if you are on the previous AOSP build you can simply dirty flash the current build and stuff should work out fine, However, if you are on a ancient build of AOSP, You are advised to do a clean flash over latest RUI 1.0 (Android-10 firmware) for your respective variant, Please note builds made from my tree are compatible across all the variants marketed under the umbrella of Realme X2 be it RMX1991,1992,1993, So stop sending me dm(s) asking if it would work.
