Not correct. AdbAppControl can be used to run your scripts. The console tab is used. Once adb root, adb remount and adb shell(you can just click shell tab on right side to go right to shell prompt) are run a cmd window opens up just like with Sdktool by default when you start ADB.
The advantage of using ADB App control is it's a gui for those that are not techies and allows for owner to choose what to disable and can re enable all in seconds. Preset can be saved for future use. You can script it like you have been doing for debloat but your script is going to grow and grow with more and more variables needing to be set. If one does not use BT it can be disabled as it's driver gets loaded and becomes a cached process for example see Pic.
The default launcher/QuickStep is a resource hog and needs to be replaced with Olauncher which uses far less and allows you to swipe left or right from home screen to start your music apps. See pic
Google keyboard can be replaced with simple which uses less resources and gboard disabled.
I will be moving my guides back on here due to npaudio site mostly being shut down at the moment. I will update them to include your GREAT work giving you credit of course for your work as it's not mine. You are a linux expert which I am not.
I would love to work together on this especially since I own 2 Dx340s for now so can easily test SQ changes back to back. Probably will sell one. This is for the benefit of all Dx340 owners. I know I am not your favorite person in the world but we can still work together like UK, USA and Russia did for a common purpose in WWII except I would never try to take over your own work.
Why has no one tried your custom.rc on Dx320(max), Dx180, Dx260? Debloat as far as modules that need to be disabled will be different because of some different modules on android 11 and 180 has 2 different ones. I have them all in my guides. Your tweak likely will work on entire current ibasso Dap line. If I had a 180 or 320 I would try on them. Easy to undo if issue. You verify that model is Dx340 so that would have to be modified.
Polished both 340s again and now even have better shine for those that want them to look like 320x.
I will end this post with a Pic of spring break in FL one block walk from where I live.
