What is a Bootloader?

Title: [Guide] How to Unlock the Bootloader on the Black Shark 2 (KLE-A0)

Unlocking the bootloader on the Black Shark 2 is the first step to rooting your device, installing custom ROMs (like Pixel Experience or LineageOS), or flashing custom kernels. However, the process is slightly different from standard Xiaomi devices because Black Shark uses its own unlock tool.

Here is a step-by-step guide to getting it done safely.

⚠️ Important Warnings Before You Begin

• Warranty: Unlocking the bootloader may void your warranty.
• Data Loss: This process will wipe all data on your phone. Make sure to back up photos, contacts, and files to a PC or cloud service before starting.
• Anti-Rollback: Do not flash older firmware versions than what is currently on your phone. Black Shark devices have Anti-Rollback Protection (ARB) which can hard-brick your device.
• Banking Apps: Unlocking the bootloader breaks SafetyNet/Play Integrity. Banking apps and games like Pokémon GO may not work until you pass SafetyNet (usually fixed by installing Magisk later).

3. Standard Xiaomi Process (Unsuccessful)

The standard method for Xiaomi phones fails on the Black Shark 2 for two reasons: Unlocking the Bootloader on Black Shark 2: A

1. Deep Flash Testing: Binding the account in Developer options → Mi Unlock status does not create a valid unlock token.
2. Mi Unlock Tool Error: The tool typically returns "Current account is not bound to this device" or "Unlock failed (10008)".

Conclusion: The official method is blocked by Black Shark’s customized bootloader.

Error: "Device not supported in Mi Unlock Tool"

Solution: Use the specialized Black Shark Unlock Tool, or update your Mi Unlock tool to v6.5.112.25 or newer.

Phase 1: Developer Options and OEM Unlocking

1. On your Black Shark 2, go to Settings > About Phone.
2. Tap "Joy UI version" 7 times until you see "You are now a developer."
3. Go back to Settings > Additional Settings > Developer Options.
4. Enable OEM Unlocking (This is critical. If greyed out, connect to Wi-Fi and wait 10 minutes).
5. Enable USB Debugging.

6. Failure & Recovery Scenarios

| Problem | Likely Cause | Recovery | |---------|--------------|----------| | Device won't boot, only shows "press any key to shutdown" | Corrupted bootloader after bad abl flash | EDL mode + QFIL restore of stock firmware | | fastboot oem unlock returns Command not allowed | OEM unlock disabled in OS or wrong command | Re-check Developer options; try fastboot oem unlock-go | | Stuck in fastboot loop | Mismatched boot.img or vbmeta | Flash stock boot/vbmeta for your MIUI version |

EDL Pinout (Test Points): Requires opening the back cover and shorting two test points (marked TP403 and TP404 near the battery connector).

Troubleshooting Common Errors

Phase 5: Verification

Your phone screen will show a warning about the bootloader being unlocked. Use the volume keys to select "Unlock" and press power. The phone will factory reset and reboot.

Congratulations! On reboot, you will see an "Unlocked Bootloader" warning screen for 5 seconds before booting. You have successfully performed a Black Shark 2 unlock bootloader operation.

Important Notes for Black Shark 2

• No official TWRP exists for BS2. Use modified versions from XDA forums.
• Do NOT relock the bootloader with non-stock software – it hard bricks the device.
• Global vs Chinese model: The unlock process works for both, but Chinese models may have additional restrictions.

If you get stuck, search the XDA Forums (Black Shark 2 section) – the community there maintains updated unlock tools and driver fixes.
