The Huawei MediaPad M3 (model numbers BTV-DL09, BTV-W09) was released during a transitional period for Huawei. While older Huawei phones had official unlock codes, and newer ones are permanently locked, the MediaPad M3 sits in a gray area.
Unlike older devices, Huawei no longer provides official unlock codes through its website. Therefore, this guide focuses on the universal ADB/Fastboot method which may work depending on your specific firmware version, and outlines the necessary steps to prepare your tablet.
In 2021, a Russian developer released "PotatoNV," which exploits a vulnerability in Huawei's Kirin 960 chipset (which powers the MediaPad M3). This bypasses the need for a code.
Requirements:
Unlocking the Huawei MediaPad M3 is becoming increasingly difficult due to the lack of official support from Huawei. While the fastboot oem unlock method works on older firmware versions, newer security patches may render the bootloader permanently locked.
If you require a custom ROM or Root access, check XDA Developers forums for your specific model number (BTV-DL09 or BTV-W09) to see if specific exploits or methods have been discovered recently.
Unlocking the bootloader of a HUAWEI MediaPad M3 is a multi-step process that requires obtaining a unique unlock code.

Overall Rating: ⭐⭐☆☆☆ (2/5 – for practical usefulness in 2025+)
Pros:
Cons:
Verdict:
If the guide was written before 2019, it’s obsolete. For a Huawei MediaPad M3 on EMUI 5+ (Android 7+), you realistically cannot unlock the bootloader without paying for a third-party service (e.g., HCU, Ministry of Solutions). Most free tutorials are now a waste of time. If the guide doesn’t mention paid remote unlocking or an exploit like PotatoNV (which doesn’t support Kirin 950), skip it.
Better approach today: Search for “Huawei bootloader unlock paid service 2025” or accept that the device remains locked.

Yes, if: You are a developer who needs LineageOS 20 (Android 13) on the MediaPad M3, or you want to de-Google your device.
No, if: You just want to remove bloatware. You can disable apps via ADB without unlocking the bootloader (pm disable-user --user 0 com.huawei.bloat).
Because Huawei actively blocks bootloader unlocking, only Method 1 (Paid DC-Unlocker) is recommended for 99% of users. Methods 2 and 3 are obsolete or dangerously complex.
This is the critical step. Since Huawei does not provide codes anymore, we must attempt the universal unlock command.
