- If your target device has a custom firmware flash counter, Rooting will trigger it. If you’re lucky, Triangle Away has support for your device and can be used to reset the counter.
- If you have a KNOX-enabled device, Rooting will trip the KNOX WARRANTY VOID status !
- If your device storage is encrypted, Rooting will wipe your data !
