  1. Use at your own risk, I’m not responsible for bricking your device.
  2. Using the incorrect file may brick your device.
  3. 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.
  4. If you have a KNOX-enabled device, flash custom rom and Rooting will trip the KNOX WARRANTY VOID status!
  5. If your device storage is encrypted, Rooting will wipe your data !
  6. If you have locked bootloaders, flashing one of these will probably brick your device – with the exception of Nexus devices, which will usually automatically “OEM unlock” and wipe your data !
  7. Make sure to backup your important data before root it.
