Disclaimer: Unlocking your bootloader will wipe all data on your device. It voids your warranty and may cause security vulnerabilities. This process is for advanced users. The author and platform are not responsible for bricked devices or data loss. Huawei no longer officially provides unlock codes.
If your MediaPad M3 is running EMUI 8.0 (Android 8.0), you cannot use the free software exploits because Huawei patched them. You must downgrade to EMUI 5.0 (Android 7.0).
If your device requires a password, you will need to look for third-party paid services or "DC-Unlocker" software (a popular tool for Huawei modems and some older phones), though support for the MediaPad M3 specifically is hit-or-miss. Beware of "free code generators" found online, as these are often malware.
Unlocking the bootloader on a HUAWEI MediaPad M3 in 2026 is not officially possible but is technically achievable using the PotatoNV exploit. This method is preferred because it requires no payment and works on most BTV-W09 (Wi-Fi) and BTV-DL09 (LTE) units still running Android 7.0 or lower.
Final Recommendation: Only attempt this if you have prior experience with Android flashing and accept the risk of bricking a legacy device. For most users, the benefits (custom ROMs, root, debloating) do not outweigh the effort and potential loss of Widevine L1.

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.
Unlocking the bootloader on a Huawei MediaPad M3 requires a 16-digit code, which must be obtained via third-party tools like DC-Unlocker or open-source exploits such as PotatoNV, as Huawei ceased official support in 2018. Once the code is obtained, the process involves enabling USB debugging, connecting in fastboot mode, and executing the unlock command, which will factory reset the device. For a comprehensive guide, refer to HardReset.info
To unlock the bootloader of a HUAWEI MediaPad M3, you must first obtain a unique 16-digit unlock code. Once you have this code, the process involves using ADB and Fastboot commands on a computer to communicate with the tablet. Important Warning
Unlocking the bootloader will factory reset your device, erasing all internal storage data. Ensure you have a complete backup of your files before proceeding. 1. Obtain Your Device Information
To generate or request an unlock code, you need specific identifiers found in your tablet's settings or service menu: Model Name: Found in Settings > About tablet. Serial Number: Found in Settings > About tablet > Status. IMEI/MEID: Dial *#06# on the keypad.
Product ID: Dial *#*#1357946#*#* to reveal your unique 8-digit Product ID. 2. Acquire the Unlock Code Disclaimer: Unlocking your bootloader will wipe all data
Huawei officially stopped providing unlock codes in 2018. However, legacy devices like the MediaPad M3 can still be unlocked using the following methods:
Third-Party Services: Tools like DC-Unlocker or Ministry of Solutions are commonly used by the community to generate codes for a small fee.
Open Source Tools: Some users utilize tools like Potato Envy (available on GitHub) which may require opening the device to use a hardware "test point" method. 3. Prepare the Tablet
Unlocking the bootloader on a HUAWEI MediaPad M3 is no longer possible through official channels, as Huawei terminated its official unlock code service on July 25, 2018. To unlock the device today, you must use unofficial third-party methods. Prerequisites
Back Up Data: Unlocking the bootloader triggers a factory reset, erasing all personal files.
Install Drivers: Download and install Huawei HiSuite on your PC to ensure all necessary USB drivers are present.
ADB & Fastboot: Install ADB and Fastboot tools to communicate with the tablet from your computer.
Enable Options: On your tablet, go to Settings > About tablet and tap Build number 7 times. Then, in Developer Options, enable USB Debugging and OEM Unlock. Method 1: Using PotatoNV (Recommended/Free)
Since the MediaPad M3 uses the Kirin 950 chipset, you can use the open-source PotatoNV tool. This requires opening the tablet's back cover to access a "testpoint" on the motherboard. Unlocking the bootloader on a HUAWEI MediaPad M3
Some BTV-DL09 (LTE) variants require hardware testpoint.
