## 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.
