Completely eliminate linked HeyTap Account (OPPO ID / OPPO Cloud) lockouts from OPPO smartphones and tablets with the official server database clearance service on GrandUnlock. Tailored for professional GSM repair facilities, refurbishment workshops, and diagnostic technicians dealing with post-wipe locks or forgotten account credentials, this service permanently unlinks the hardware identifier directly from central HeyTap authentication servers without requiring temporary bypass apps, patched boot images, or hardware ISP drilling.

- Permanent Server-Side Clearance: Once processed and cleared on the server database, the hardware association is severed permanently. The device can be updated via OTA (ColorOS), factory reset, or registered to an entirely new HeyTap ID without relocking.
- Full Lineup Compatibility: Supports all OPPO Find series, Reno series, A series, K series, and Find N foldable models across Qualcomm Snapdragon, MediaTek (MTK), and Unisoc chipsets.
- Clean Status Support: Fully verified, permanent clearance for eligible clean devices displaying standard activation lock prompts.
- 100% Remote / Over-The-Air Processing: Executes entirely via the on-screen Lock Code (Verification String) and device IMEI—no testpoints, disassemblies, or physical cables needed.

Important Technical Requirements & Workshop Policies:
1. Lock Screen Verification:
   - This service is strictly for devices locked to an OPPO ID / HeyTap Account prompt ("This phone is linked to a HeyTap ID").
   - If the handset is locked exclusively to a Google Account (FRP) with no HeyTap prompt, utilize standard FRP servicing rather than this database queue.
2. Clean Devices Only:
   - This service is restricted strictly to Clean units. Handsets flagged as Lost, Stolen, or showing owner recovery phone numbers with lost messages will be rejected by the server database.
3. Accurate Identifier Submission:
   - Submit the complete Lock Code / verification string and device IMEI exactly as displayed. Typographical errors may lead to server rejections or non-refundable processing delays.
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 balance.

How to Retrieve Device Information:
1. Power on the device to the screen displaying "This phone 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 ColorOS build.
4. Dial `*#06#` or check the SIM tray to retrieve the IMEI.
5. If an alphanumeric Lock Code or verification string is displayed underneath the password prompt, record it exactly as shown.
6. Submit 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.
