Around 9 months ago i managed to install pixel experience on my Redmi Note 7 through some YouTube videos and I knew what i was getting into and all the risk and all. So I managed to install it properly nothing bad happened and now i gotta update it actually update came a long time ago i don't have any idea how to do it. I kinda know that it similarly to what i did during installation but i don't want to do it all myself trying to figure it out. So I need some direct help what i need to do in order to update.
TL;DR Teach me how to update pixel experience.
