You can always check https://www.hovatek.com/forum/ It's similar to xda. People often ask about how to unbrick their phones (another risk you have to deal with when installing custom roms) but you can also ask if someone managed to install an unofficial rom on the same model as yours. I've been using custom roms since 2011 but i stopped with my current phone (Tecno Spark 20) cause i bricked it and couldn't revive it. Luckily i managed to find a shop with the official unbrick tools. So now i'm sticking to stock. I'm using the Adguard app with vpn to block most ads I'm mostly satisfied with what I have so until i get another phone, i'm out of the game right now.
