Notice

Warning

This script cannot help detect hidden ARB (Anti-Rollback) mechanisms. Therefore, please exercise extra caution even if your device's ARB Index shows 0x0.

Caution

Until a way to bypass or break the ARB mechanism is available in the community, you must never attempt to downgrade on your device, as this will result in a hard brick.
