As an example today we will install custom rom in android s20. Due to the lack of new OS updates, many people are now moving towards Custom ROM. And to install Custom ROM, a Custom Recovery is required.
Since it was released 5 years ago, it is no longer receiving OS updates. The last Android or OS update for the S20 series was One UI 5.1 with Android 13, since then no official OS update has come or will come, but Android Security updates may come. so today I have brought TWRP Recovery for you guys. Let's start 🙂

NOTICE
Before doing this, be sure to back up important files, images, videos, etc. Also, remove all accounts on your phone (Settings > Accounts), especially the Google Account, because since the mobile will be factory reset, if you do not know the account password, FRP Lock may occur.

Our work is done, TWRP is installed. Now you can flash Custom ROM, Custom Kernel, Modules, etc. if you wish. I have tried to make the post very detailed step by step so that you can understand it well.
I hope this post will be understandable even to a clumsy person who has never done this in their life. However, if you have any trouble understanding anything, please let me know in the comments or contact me on Facebook.
