What is the best dual boot Android OS for getting easy root and unroot access?
First you have to be aware that what device is considered &quot;rooted&quot; by an app depends on the app. Some apps may consider a device rooted, other not and the other way around.
Second the term &quot;rooted&quot; is often used in a very generalized way, in the meaning of &quot;the system is not genuine&quot; or &quot;the system seems to be manipulated&quot;. If the device offers a su binary to get root access or not is usually just one of multiple factors an app will check.
Furthermore emulators and custom &quot;ROMs&quot; like Androidx86 are usually always detected as &quot;rooted&quot; devices, because they are not official Google Android devices. Only physical Android devices, certified by Google can pass the &quot;Google's SafetyNet&quot; check which is commonly the first test performed by an app for a rooted device.
Therefore depending on what checks the app performs you might not succeed no matter what modifications you do to Androidx86. The app may always detect the system as &quot;rooted&quot; (not genuine).
The only real way to bypass this root check is usually to reverse engineer the app, check what &quot;root&quot; check it performs and modify the app using apktool or Frida so that the root check returns the desired result (only works if there is not a back-end involved that checks e.g. the Google SafetyNet check result).
