Unable to Disable System Packages, While Uninstallation is Possible

[LorandMarton]

Describe the bug

It appears that this is likely not a bug in UAD-ng itself but rather an issue related to ADB or Android system permissions. When attempting to disable packages, such as com.qualcomm.location.

The following error is encountered:

Exception occurred while executing 'disable-user':
java.lang.SecurityException: Cannot disable system packages.

However, I am able to uninstall these packages using UAD-ng, suggesting that the issue may be with ADB's ability to disable system-level packages, likely due to system protections enforced by the OS.

Android OS: Xiaomi HyperOS 1.0.5.0 UKDEUXM
ADB Version: Latest (Android Debug Bridge version 1.0.41 Version 35.0.2-12147458)

Does anyone have ideas or suggestions for a potential workaround for this issue?

When the popup appears with Failed to perform ADB operation, the log cannot be copied.

Expected behavior

It should be possible to disable system packages.

Operating System

Windows

I appreciate you're reporting this, but as this is a question related to ADB and not an issue with UAD-ng, I will be converting this to a Discussion.
