Devices Until Android 11 with engineering firmware:

There is also a chance that your device is vulnerable to one of the MTK or Unisoc [exploits](/README.md/#universal-soc-based-methods).
Side note, on the A11 link there is a collection of apps to grant a system shell, but they would probably only work on old models.
