Permanently eliminate linked HeyTap Account (OnePlus Account / HeyTap ID / Cloud) lockouts from OnePlus smartphones and tablets with the official server database clearance service on GrandUnlock. Following the unified codebase architecture across ColorOS and OxygenOS, modern OnePlus devices utilize HeyTap backend infrastructure for device security and cloud management. This service permanently unlinks the hardware identifier directly from central HeyTap authentication servers, restoring full system access without requiring temporary application bypasses, patched boot images, or risky EDL hardware testpoint procedures.

- Permanent Server-Side Clearance: Once processed and cleared on the server database, the hardware association is unlinked at the root level. The device can be updated via official OTA releases (OxygenOS / ColorOS), factory reset, or registered to an entirely new HeyTap ID without relocking.
- Full Model Lineup Compatibility: Supports all OnePlus flagship series (OnePlus 8, 9, 10, 11, 12, 13, and Open series), OnePlus Nord series (Nord, Nord CE, Nord N series), and OnePlus Pad tablets.
- Chipset Coverage: Operates across all Qualcomm Snapdragon and MediaTek Dimensity OnePlus architectures.
- Clean Status Support: Fully verified, permanent clearance for eligible clean devices displaying standard activation lock prompts.
- 100% Remote / Over-The-Air Processing: Executes completely via the on-screen Lock Code (Verification String) and device IMEI—no testpoints, disassemblies, or remote PC connection sessions needed.

Important Technical Requirements & Workshop Policies:
1. Lock Screen Verification:
   - This service is strictly intended for OnePlus handsets locked to an official HeyTap / OnePlus Account login screen ("This device is linked to a HeyTap ID").
   - If the device is locked exclusively to a Google Account (FRP) without an active HeyTap ID prompt, use the standard FRP bypass service instead.
2. Clean Devices Only:
   - Only Clean handsets are eligible for submission. Handsets reported Lost, Stolen, or showing owner recovery phone numbers with lost messages will be rejected by the server database.
3. Accurate Identifier Submission:
   - Provide the complete Lock Code / verification string and device IMEI exactly as displayed. Any typographical error in the submitted identifiers may result in rejection or lost processing credits.
4. Non-Refundable Processing Policy:
   - Orders are queued directly into automated server APIs. Once an order status changes to "In Process", it cannot be canceled, amended, or recalled.
   - If the server rejects the order due to "Device Ineligible" or "Server Offline", full credits are automatically refunded to your GrandUnlock account balance.

How to Retrieve Device Information:
1. Power on the device to the screen displaying "This device is linked to a HeyTap ID".
2. Tap the Emergency Call dialer on the setup screen and dial `*#899#` to open the EngineerMode / Aftersales menu.
3. Select "SoftwareVersion" to view and record the Model, Android Version, and OS build.
4. Dial `*#06#` or inspect the SIM tray to retrieve the IMEI.
5. If an alphanumeric Lock Code or verification string is displayed underneath the password prompt, copy it down exactly as shown.
6. Enter the IMEI and Lock Code into the required fields on GrandUnlock, then complete checkout.

How to Complete the Unlock Once Order Status is "Completed":
1. Confirm that your order status displays "Completed" on your GrandUnlock dashboard.
2. Turn on the device and connect it to a stable Wi-Fi network.
3. Restart the phone or tap the activation button on the screen.
4. The HeyTap ID lock screen will dismiss automatically, allowing you to proceed with standard device setup.
