Let’s dissect the string: adb shell sh /storage/emulated/0/Android/data/moe.shizuku.privileged.api/start.sh
You are issuing an instruction to your Android device via your computer's ADB interface to do the following:
adb shell ls /storage/emulated/0/Android/data/moeshizukuprivilegedapi/
As discussed, this is the most common error on Android 11 and above, where access to /Android/data/ is heavily restricted, preventing the ADB shell from executing the script from its original location.
Permission denied
Pick one and I’ll provide safe, actionable guidance.
Without the ADB shell command, Shizuku would have no way to bootstrap its service. This is why the command is required—it’s the one-time (or per-boot) elevation event.
