It's hard-coded into smali, substratum can't modify smali files, on most other Android roms (mostly AOSP roms or on the Pixels) the wifi and data icons are also coded in smali since oreo or something so I think we should be happy OnePlus still uses the old method.
Well yes, in theory we could, with Magisk you ca change almost every file of an app because it literally replaces the whole apk, this means you could also change smali files but it also means it's way more likely to cause bootloops and other issues since it doesn't just change a drawable or something but the whole app package and you'll have to make a new version for every single device and for almost every single update. I know there's a module that did it for the OnePlus 6 but that one seems abandoned too. Maybe someone could make a new one but I'm not planning on maintaining something like that. As of your second question, well, since OnePlus uses the old method instead of the new one we're still able to theme the wifi and data icon using Substratum, on Pixels for example you can't do that anymore because they use the new method and put these icons in smali.
Oof that sounds time consuming ?. OHHH I thought you said OnePlus also codes the Wifi and Data in smali I was confused.
Did you even read the first post, there's literally an paragraph about supported devices and it would have told you custom roms aren't supported.
Could you also see if you could change the gesture bar to the smaller Pixel one? I know you could do that with the old navbar icons before with a simple drawable swap but this one might be different because they actually animate and tweak its color dynamically
Yes but that also turns off custom accent color for some stupid reason. I think you should still add it
No, but I haven't had much time because of school and family. I'll soon try to update the theme.
No they aren't, they are material design icons, I'm already planning on also porting the Pixel icons over but that will take some time
