Users often report fewer issues with boot loops or dm-verity errors when the initial unlock is done via the token method, as it properly initializes the unlocked state in the bootloader's logic. It ensures that if a phone is stolen,

If you are modifying a carrier-branded OnePlus device (e.g., T-Mobile), standard commands will fail with the token error. You must flash an official cryptographic token identifier.

Open a command prompt or terminal on your computer and navigate to the platform-tools folder in your Android SDK directory.

Modern OnePlus devices require two layers of permission before the bootloader can be unlocked:
