Unlock Bootloader Huawei: Full Guide

Unlocking the bootloader on a Huawei device lets you install custom firmware, root the phone, and flash custom recoveries, but Huawei stopped providing official unlock codes in 2018, so the only legal route today is using a paid third-party service. This guide explains what bootloader unlocking means for Huawei phones, the risks, the methods that still work, and what to do after you get the code.

What a Bootloader Is and Why Huawei Locks It

The bootloader is the first piece of software that runs when you power on a phone. It initializes the hardware and loads the operating system. On most Android devices, the bootloader is locked by default to prevent unauthorized modifications. Unlocking it allows you to flash a custom recovery (like TWRP), install a custom ROM (like LineageOS), or gain root access with Magisk.

Huawei locked bootloaders more strictly than most manufacturers. Until 2018, you could request an official unlock code from Huawei’s website by providing your device’s serial number and IMEI. After that, Huawei stopped issuing codes entirely, citing security and user safety. This means new Huawei and Honor devices (Honor is a sub-brand) cannot be unlocked through official channels, and the only way is to use a third-party service that derives the code from Huawei’s algorithm.

Why People Unlock Huawei Bootloaders

There are several common reasons a user would want to unlock a Huawei bootloader:

• Install custom ROMs: To get a newer Android version after Huawei stops providing updates, or to use a lighter, stock-like OS.
• Root access: To remove bloatware, use ad-blockers, or run apps that require root privileges.
• Custom recovery: To make full system backups, wipe data more thoroughly, or flash ZIP files.
• Remove carrier bloat: To delete pre-installed apps that cannot be uninstalled normally.
• Repair a soft-bricked device: Some unbricking procedures require an unlocked bootloader.

However, the effort is significant, and the risk of bricking the phone is real. For most users, the benefits do not outweigh the potential for a non-functional device.

How Huawei Bootloader Unlocking Works Now

Since Huawei no longer provides official codes, the only method that works for most models is to buy a code from a third-party service. These services typically work as follows:

1. You find your device’s serial number and IMEI. You can find these by dialing *#*#1357946#*#* (for older models) or by going to Settings > About Phone > Status, or by typing fastboot oem get-product-model in fastboot mode.
2. You provide these numbers to the service, often through a website or a Telegram bot.
3. You pay a fee (usually between $20 and $50, depending on the model and service).
4. The service generates an unlock code using a leaked or reverse-engineered version of Huawei’s algorithm. This can take from a few minutes to a few days.
5. You boot your phone into fastboot mode (power off, then hold Volume Down + Power), connect it to a PC, and run the command: fastboot oem unlock [your_code].

Some services also offer a “remote unlock” where they guide you through the process step-by-step. The code is unique to your device’s IMEI and serial number, so it cannot be shared between phones.

Risks and What You Lose

Unlocking the bootloader voids your warranty and triggers a permanent warning on the boot screen. More importantly, it makes your device more vulnerable to malware because the bootloader no longer verifies the integrity of the boot image. Other risks include:

• Bricking: Flashing an incompatible ROM or recovery can make the phone unbootable. While many bricks are recoverable with the right tools, some are not.
• Data loss: Unlocking the bootloader wipes all data on the device. Back up everything before you start.
• Loss of Widevine L1: Some devices lose the ability to stream HD content from Netflix and other services after unlocking.
• Banking apps may stop working: Google Play Integrity checks fail on unlocked devices, so apps like Google Pay may refuse to run.
• No official updates: Huawei’s OTA updates may fail to install on an unlocked device, and you will have to manually flash updates.

There is also the risk of the third-party service scamming you. Only use services with a track record and positive reviews from multiple sources. Never send your IMEI to a service that asks for more than the serial number and IMEI.

How to Unlock a Huawei Bootloader (Step-by-Step)

If you have obtained a code, here is the general procedure. It is the same for most Huawei and Honor models with an unlockable bootloader:

1. Back up all data. Unlocking wipes the phone completely.
2. Enable Developer Options: Go to Settings > About Phone and tap “Build Number” seven times.
3. Enable OEM Unlock: In Settings > Developer Options, turn on “OEM unlock” (if the option exists; on many Huawei phones it is hidden or absent).
4. Install ADB and Fastboot tools on your PC. These are command-line tools from Google’s Android SDK.
5. Boot into fastboot mode: Power off the phone, then press and hold Volume Down + Power simultaneously until the fastboot screen appears.
6. Connect the phone to the PC with a USB cable.
7. Verify the connection: Open a command prompt in the folder where fastboot.exe is located and type fastboot devices. You should see your device listed.
8. Run the unlock command: Type fastboot oem unlock [your_code] and press Enter. Replace [your_code] with the code you received.
9. Confirm on the phone: A prompt will appear on the phone asking to confirm the unlock. Use the volume keys to select “Yes” and press the power button.
10. Wait for the wipe: The phone will reboot and erase all data. After it boots, the bootloader is unlocked.

If the command fails with an error like “FAILED (remote: unknown command)”, the bootloader may not support that command. Some older models use fastboot oem unlock-go or fastboot flashing unlock. Try those alternatives.

Alternatives to Unlocking

If you cannot or do not want to unlock the bootloader, there are a few alternatives that achieve some of the same goals:

• Use a paid bootloader unlock service (the only real alternative for Huawei).
• Stay on the stock ROM and use “private space” or “app twin” features to isolate apps.
• Use a different phone that allows official bootloader unlocking, such as many Xiaomi, OnePlus, or Google Pixel devices.
• Use a “systemless” root method that does not require an unlocked bootloader? No, there is no such method for modern Huawei devices.

In short, if you need root or custom ROMs, unlocking is the only way, and for Huawei, that means paying a third party.

Frequently Asked Questions

Can I unlock a Huawei bootloader for free?

No. Huawei stopped providing free official unlock codes in 2018. There is no free method that works on modern Huawei devices. Some very old models (pre-2018) may still have codes available through the official website, but that site is now defunct. All working methods involve paying a third-party service.

Is it legal to unlock a Huawei bootloader?

In most countries, unlocking a bootloader is legal, but it voids the warranty. However, using a third-party service to generate a code may violate Huawei’s terms of service. The legality of circumventing a lock is not the same as the legality of the unlock itself. In the US, the DMCA has exemptions for unlocking phones for the purpose of interoperability, but it is a gray area.

Will unlocking the bootloader remove the Huawei ID lock?

No. The bootloader unlock is separate from the FRP (Factory Reset Protection) lock that is tied to your Huawei ID. Unlocking the bootloader does not remove the FRP lock. You must still enter the Huawei ID credentials that were on the phone before a factory reset.

Does unlocking the bootloader improve performance?

Not directly. The bootloader itself does not affect performance. However, after unlocking, you can install a custom kernel or a lighter ROM that may feel faster. But the stock EMUI is already optimized for the hardware, so the gains are usually minimal.

Can I relock the bootloader after unlocking?

Yes, you can relock it with the command fastboot oem relock [your_code]. However, relocking after flashing a custom ROM may cause boot issues. Also, relocking does not restore the warranty or make the phone “stock” again if you have modified the system partition.

What if I brick my phone during the unlock?

If the unlock command fails or you flash a bad image, you may be able to recover by flashing the stock firmware using Huawei’s HiSuite or the eRecovery mode. If the device is completely dead (no response to power or charging), you may need a paid service to repair it. There is no universal fix for all bricks.
