Troubleshooting
Issues installing or upgrading from another Superuser or SuperSU? Try the recovery zip installation linked below.
Apps being denied? Disable the "Declared Permission" setting, and delete the "Deny" policies.
This app requires that you already have root, or a custom recovery image to work.

Why another Superuser?
* Superuser should be open source. It's the gateway to root on your device. It must be open for independent security analysis. Obscurity (closed source) is not security.
* Superuser should be NDK buildable. No internal Android references.
* Superuser should also be AOSP buildable for those that want to embed it in their ROM.
* Superuser should also be AOSP embeddable, meaning a ROM can easily embed it into their Settings app.
* Maintenance and updates on both the market and source repositories should be timely.
* If something goes wrong, I can fix it.
* Handle multiuser (4 2 ) properly
* Handle concurrent su requests properly
