To bypass this error, you must obtain a specific token file for your device's IMEI and Serial Number.
“Please flash unlock token first” is not a bug but a deliberate enforcing that an authenticated, device-specific token be written before any flash modifications. It prevents arbitrary writes to protected partitions and is critical in anti-tamper designs. Resolving it requires obtaining the correct token from the vendor or authorized tool and ensuring it is flashed as the very first write operation in the appropriate low-level mode. Understanding the underlying bootrom and OTP mechanisms is key to efficient debugging.
Copy the long string of alphanumeric characters provided by the command. 2. Request the Token File please flash unlock token first

On carrier-locked or specific regional models, simply enabling "OEM Unlocking" in settings is not enough to grant bootloader access. The manufacturer requires a unique, cryptographically signed file (the ) to be flashed to the device before the standard fastboot oem unlock command will be accepted.

In enterprise or automotive contexts, the token is often generated server-side after verifying legal ownership, repair ticket, or subscription status. Resolving it requires obtaining the correct token from
The error says “first” because the boot sequence checks for the token enabling any flash programming interface. If you attempt to flash any other partition (system, boot, modem) without the token in place, the bootloader rejects the command with this exact error. The token must be the very first write after power cycle in programming mode.
