adb devices
adb reboot bootloader
fastboot oem get_identifier_token

| Issue | “Please flash unlock token first” on OnePlus | |-------|------------------------------------------------| | Cause | Carrier or region lock requiring official token before unlocking bootloader | | Standard fix | Get token from OnePlus → flash it → unlock | | “Better” fix (community) | Use MSM Tool to flash global firmware, bypass token requirement | | Risk | Data loss, warranty void (if still valid), DRM issues |

Unlocking the Potential: Why You See "Please Flash Unlock Token First" on Your OnePlus
If you’ve ventured into the world of Android modding with your OnePlus device, you’ve likely encountered a roadblock that looks something like this: "Please flash unlock token first."
This message can be frustrating, especially when you're eager to install a custom ROM, root your device, or experiment with Kernel tweaks. However, understanding why this happens and how to fix it is the key to a "better" OnePlus experience—one where you have total control over your hardware. Understanding the "Unlock Token" Requirement
Unlike the early days of OnePlus where a simple fastboot oem unlock command did the trick, modern OnePlus devices (particularly those sold through carriers like T-Mobile or Verizon) have an extra layer of security.
The Unlock Token is a unique file provided by OnePlus that cryptographically verifies you have permission to bootloader-unlock that specific device. Without flashing this .bin file to your phone's memory, the bootloader remains "locked," preventing any unauthorized software changes. Why Your OnePlus Experience is "Better" After Unlocking
Why go through the hassle? Enthusiasts agree that a OnePlus device truly shines once the shackles are off: If you try to run fastboot oem unlock
Bloatware Removal: Carrier-locked versions of OnePlus phones often come with "junk" apps that drain battery. Unlocking allows for a clean slate.
Extended Lifespan: When official OxygenOS updates stop, the developer community keeps the device alive with the latest versions of Android via Custom ROMs (like LineageOS).
Enhanced Performance: By flashing custom Kernels, users can undervolt the CPU for better battery life or overclock it for smoother gaming.
True Ownership: You aren't just "renting" the software experience; you own the hardware and what runs on it.
Step-by-Step: How to Resolve "Please Flash Unlock Token First"
If you are seeing this error, it means your device is expecting a signature file before it will accept the unlock command. Here is the general workflow to get it done: 1. Enable Developer Options
Go to Settings > About Device > Version and tap Build Number seven times. Then, go to System Settings > Developer Options and enable OEM Unlocking and USB Debugging. 2. Get Your Unlock Code
Connect your phone to a PC with ADB/Fastboot installed. Reboot to fastboot mode and run:fastboot oem get_identifier_tokenYou will receive a long string of characters. This is your device’s unique signature. 3. Submit the Request to OnePlus
Visit the official OnePlus Unlock Token Service (or the specific carrier portal if applicable). Paste your identifier token and IMEI. 4. The Waiting Game
OnePlus usually takes 1 to 7 days to process the request and email you the test_device_unlock_key.bin file. 5. Flashing the Token
Once you have the file, return to fastboot mode on your phone and run:fastboot flash cust-unlock Once that succeeds, you can finally run the magic command:fastboot oem unlock Common Pitfalls to Avoid
Data Wipe: Unlocking the bootloader will factory reset your phone. Back up your photos and messages before you start.
Warranty Concerns: In many regions, unlocking the bootloader does not void the hardware warranty for OnePlus devices, but it may void your software support. Always check your local terms.

The error message "Please flash unlock token first" typically occurs on carrier-locked OnePlus devices (particularly T-Mobile variants) when attempting to unlock the bootloader without the required proprietary binary file. Unlike global models, these variants require a specific "unlock token" from OnePlus before the standard unlock commands will work. Why You're Seeing This Error
On carrier-branded OnePlus phones, the bootloader is double-locked. Even if you have "OEM Unlocking" enabled in settings, the device will reject the fastboot oem unlock command until a valid token is flashed to the cust-unlock partition. How to Get and Flash the Token
To bypass this error, you must follow the official OnePlus Unlock Service procedure:
SIM Unlock First: Ensure your device is fully SIM-unlocked by your carrier.
Enable Developer Options: Go to Settings > About Phone and tap Build Number 7 times.
Enable OEM Unlocking: In Developer Options, toggle on OEM Unlocking and USB Debugging. Retrieve Unlock Code: Boot into Fastboot mode. Run the command: fastboot oem get_unlock_code.
Submit to OnePlus: Provide your IMEI and the retrieved unlock code to the OnePlus unlock portal.
Wait for the Token: OnePlus typically emails a .bin file within 7 days.
Flash the Token: Once you have the file (e.g., unlock_token.bin), run: fastboot flash cust-unlock unlock_token.bin.
Final Unlock: Finally, run fastboot oem unlock or fastboot flashing unlock to finish the process. Alternative: Converting to Global Firmware How to unlock bootloader for OnePlus smart Phone
