Unlocking the Huawei P9 Lite 's bootloader without an official code is technically challenging because Huawei officially terminated its unlock code application service on July 25, 2018. Since then, users must rely on third-party software or open-source hardware-based exploits. Understanding the Hardware Exploit (PotatoNV) The most reliable current method for the Huawei P9 Lite
(and other Kirin 65x based devices) is using PotatoNV, an open-source tool. This method does not require an original manufacturer code but does require physical access to the device's motherboard.
Requirements: You must open the device and short a specific test point to the metal shield or ground while connecting the USB cable to enter "Huawei USB COM 1.0" mode. Tool: The PotatoNV GitHub repository
provides the necessary software to generate a new 16-character unlock code and perform the unlock.
Compatibility: This method works specifically for Kirin 650, 655, 658, and 659 chipsets found in Third-Party Paid Services
If you prefer not to open your device, several paid services maintain their own databases or algorithms to generate codes, though these are not officially endorsed and involve risk.
The Huawei P9 Lite is old, but it’s still a great device for custom ROMs. Unlocking the bootloader without a code is absolutely possible—you just need to get physical with the test point. It takes 10 minutes and zero dollars. fastboot flash recovery twrp_p9_lite
Pro-tip: Once unlocked, flash LineageOS 18.1 (Android 11). It makes the P9 Lite feel like a new phone.

Unlock safely. Flash freely.
Unlocking the Huawei P9 Lite bootloader without an official code is possible, though it now requires unofficial tools since Huawei terminated its official unlock code service in July 2018.
Because the manufacturer no longer provides codes, you must use hardware-based exploits or third-party tools to bypass this restriction. Recommended Unofficial Methods
Since you cannot get a code from Huawei, these are the primary remaining options:
PotatoNV (Open Source): This is a popular open-source tool that works by deciphering the unlock code generation algorithm for devices with specific Kirin chipsets (like the Kirin 655 found in some P9 Lite variants).
Process: It requires opening the phone to access the motherboard and shorting a "test point" to enter a low-level VCOM_DOWNLOAD mode. Summary The claim — unlocking the Huawei P9
Resources: Detailed guides and the tool itself can be found on GitHub.
Third-Party Paid Services: Services like DC-Unlocker or SigmaKey are known to still work for older Huawei models. These often require a small fee to read the bootloader code directly from the device via USB.
Brute-Force Tools: Some scripts, like those found on GitHub, attempt to "brute-force" the 16-digit unlock code. This method is highly time-consuming and may not be successful on all software versions. Essential Preparation Steps
Regardless of the method used, you must prepare the device first:
How to Unlock Bootloader in HUAWEI P9 Lite 2017 phone?, How To
I understand you're looking for a guide on unlocking the bootloader of a Huawei P9 Lite, specifically "without code" (likely meaning without the official unlock code from Huawei). However, I need to be clear upfront: Huawei officially shut down its bootloader unlock code service in 2018. There is no legitimate, free, or "extra quality" method to unlock the bootloader without using either:
Below is a factual, technical write-up covering the only methods that have ever worked for the P9 Lite (model L21, L31, etc.), including the risks and limitations. I will not provide direct links to paid services or cracked tools, but I will explain the process.
