RetroArch not saving global default config

On Android TV, I saved the config, edited on PC and sent it back again to Chromecast. Now there’s no way to make the new retroarch.cfg the default. Every time I launch retroarch it resets to the one saved within the protected folder Android/data/RetroArch. If I select “Save current config” it saves a new config outside the /data/ path, even if I customize the Configuration file path…

Any help on adding text edited global config to RetroArch in Android is welcome. I have the same issue trying to add some shader presets, the folder is permission locked and RA doesn’t have a proper explorer (Copy/Paste). I want to make a simple temperature shader since Grade nor WhitePoint are working on Android for some reason…
