Xiaomi HyperOS 3 tweaking

I didn't bother to unlock/root my Redmi Note 15 5G, there are enough ways to cutomize this Android HyperOS (Android16)

Do the usual tweaks like disable ads, uninstall  system apps, disable MIUI optimization and RAM expansion

Unlock option to write settings to global, system and secure db when in adb shell:
Goto Android Settings menu
Sign in to your Xiaomi Account
Enable Developer options
Goto Developer options and enable 1) USB debugging and 2) USB debugging (Security settings)

Now you are able to write settings to all settings db's and do the tweaks via adb shell (I once had to reboot to make it work)

Note: after changing settings you better turn off  USB debugging Security settings for safety!!!
Note: Windows cmd script to get all settings from your Android device via ADB: here

The tweaks

Note: just pick what you need/want. Don't copy/paste everything into adb shell
