Troubleshooting Common Errors

Troubleshooting Common Issues

"Current account is not bound to this device": This is the most common error. Go back to Step 2. Ensure you have a valid SIM card and internet. Sometimes you need to toggle the "Add account" option multiple times.
Driver Issues: If the PC does not recognize the phone in Fastboot mode, try a different USB port (preferably USB 2.0) or reinstall the Xiaomi USB drivers.
Stuck at 50% / 99%: This usually indicates a server-side issue or a network block. If you are stuck at 99%, try using a VPN on your PC or try the process at a different time of day. Note that Black Shark servers have become less reliable over time; persistence is key.

Prerequisites

A Windows PC: The unlock tool is an .exe file and generally only runs on Windows.
USB Cable: Use the original cable or a high-quality data cable.
Black Shark 2 Drivers: Download and install the Black Shark USB Drivers (often found on the official forums or XDA).
Black Shark Unlock Tool: You can find this on the official Black Shark website under "Support" or on reputable XDA Developers threads.
Battery: Ensure your phone has at least 50% charge.

Phase 4: The Fastboot Unlock Process

Power off your Black Shark 2.
Hold Volume Down + Power until you see the Fastboot logo (bunny with gears).
Connect your phone to the PC.
Open a command window in your Platform Tools folder.
Type: fastboot devices (Ensure your device serial appears).
For standard unlock: fastboot oem unlock
- If that fails: Try fastboot flashing unlock
- If that fails: You need the Black Shark specific tool. Run the .exe as Administrator, click "Unlock."
