Major_Ghost This is not a good trick because even if you did, if a competent LE held your device they can power off and turn on Fastboot in an attempt to see anything they can extract and would immediately notice GrapheneOS being installed due to it using a unique bootloader, and even if you restarted your phone, because the GrapheneOS project requires phones to display the SHA256 Verified Boot hash in full, they would know it is not stock. You gain nothing from this change.
