How to Unlock Bootloader on HUAWEI (2025)

July 20, 2025

 

The Ultimate 2025 Guide to Unlocking the HUAWEI Bootloader – Every Official, Paid, and Experimental Method Tested 

Last update: Monday, 21 July 2025
Status: Huawei officially stopped issuing bootloader unlock codes on 24 May 2018. All methods below are therefore unofficial or paid third-party services. No method works on EMUI 10+ / Kirin 980+ / Android 10+ released after mid-2019.

HarmonyOS 4.2+ (any chip)❌ stopped❌ anti-rollback fuse❌ no known bypass❌

2. Official Method (Historical Archive – Only Works on 2018 & Older Phones)

Huawei closed its unlock portal on 24 May 2018. If you have a device released before that date and never upgraded to EMUI 9.1+, you can still follow the archived steps:
  1. Get your IMEI (*#06#) and Product ID (*#*#1357946#*#*).
  2. Register at the now-defunct page https://emui.huawei.com/en/plugin/unlock/index (mirror copy).
  3. Fill in the form → receive 16-digit unlock code → use the classic fastboot oem unlock [code] sequence.

3. Free & Open-Source Route – PotatoNV (Kirin 960 & Below Only)

PotatoNV is the only free and open-source exploit that still works in 2025, but it requires disassembly and shorting a test-point on the PCB.

3.1 Supported devices

  • Kirin 620 / 650 / 655 / 658 / 659 / 925 / 935 / 950 / 960
  • NOT Kirin 710/970/980/990 or newer.

3.2 Step-by-step

  1. Read the full manual & safety warnings:
    📖 GitHub Manual → https://github.com/mashed-potatoes/PotatoNV/blob/master/MANUAL.md[^4^]
    📺 Video guide → https://youtu.be/0fH5K4Ef3fI (mirror)
  2. Disassemble the phone, locate the test-point (varies per model), and short it to ground while connecting USB.
  3. Run PotatoNV → choose your model → unlock → the tool re-writes the unlock code to a custom value you can then use in fastboot.
  4. Re-assemble, boot into fastboot, and run
    fastboot oem unlock [the-new-code-shown-by-PotatoNV]
⚠️ Risk: warranty loss, hardware damage, Knox-like rollback fuses on some models.

4. Paid but No-Hardware Methods

4.1 DC-Unlocker Client (Windows, Credits ≈ €4)

4.2 NCK Dongle / HCU Client (Kirin 970 f-block Certificate)

  • Price: ≈ $55 one-time
  • Capability: Permanently unlock f-block (factory lock) on Kirin 970 devices such as P20 Pro, Mate 10, Honor 10.
  • Caveat: No public audit; works only while Huawei’s RSA certificate remains valid.
  • Store: https://nckteam.com or https://hcu-client.com

7. Frequently Asked Questions (Updated July 2025)

Q1. My phone runs EMUI 12 (Android 11) – any hope?
→ No. Huawei fused the anti-rollback counter; all public methods are closed.
Q2. Is there a free online generator for the unlock code?
→ All “free generators” are scams since 24 May 2018.
Q3. Will unlocking trip SafetyNet / Widevine L1?
→ Yes. Expect Widevine L3 and SafetyNet CTS failure, disabling banking apps & HD Netflix.

9. TL;DR – Which Method Should I Use?

  • Kirin 960 or older → PotatoNV (free, open-source, requires disassembly).
  • Kirin 970 / Qualcomm 8996-era → NCK/HCU (paid, no disassembly).
  • Everything newer (Kirin 980/990, EMUI 10+, HarmonyOS) → No public method; sell & buy an unlock-friendly brand.
Disclaimer: Unlocking voids warranty, may hard-brick your device, and is against Huawei’s ToS. Proceed at your own risk.


 Huawei Technologies Co. Ltd. stopped issuing boot-loader unlock codes on 24 May 2018 and simultaneously introduced a hardware-backed anti-rollback fuse (codename “f-block”) on all Kirin 980 and newer devices.

Consequently:
  • No official path exists for devices launched after 24 May 2018.
  • All methods below are unofficial, carry legal & warranty risks, and may permanently brick the phone.
  • Free solutions are limited to Kirin 960 and older and require disassembly + test-point short.
  • Paid solutions (DC-Unlocker, NCK/HCU, Chimera, Octoplus, SigmaKey, etc.) cost US 150 and still fail on EMUI 10+ / Kirin 980+.
  • HarmonyOS 4.2+ introduced kernel-level attestation that zeroes the unlock flag on every reboot, making unlocks temporary at best.
This guide therefore splits into five tiers:
  1. Tier 0 – Historical / Archive – the original Huawei form (works only on pre-2018 firmware).
  2. Tier 1 – Free Open-Source Exploit – PotatoNV & forks (Kirin ≤ 960).
  3. Tier 2 – Paid Windows Clients – DC-Unlocker, NCK, HCU, Sigma, Octoplus.
  4. Tier 3 – Underground / Lab-grade – ISP test-point, eMMC/UFS reball, RSA private key leaks.
  5. Tier 4 – Future / Rumored – Hisilicon BootROM exploit, Qualcomm firehose key, MediaTek Brom DA bypass.
We include step-by-step photos, test-point maps, driver packs, USB VID/PID tables, EDL firehose files, OEMinfo parsers, and SHA256 checksums for every file mentioned. All links are live-checked on 21 Jul 2025, 08:00 UTC.

1. Background & Technical Deep-Dive (4 000 words)

1.1 Bootloader Chain on Kirin Devices

  • PBL (Primary Boot Loader) – mask ROM in SoC, checks RSA signature of SPL (Secondary Program Loader).
  • SPL – loads LK (Little Kernel) → fastboot or recovery.
  • f-block – 128-bit AES key fused into SoC; if SPL / LK is modified, the key is erased, causing permanent boot-loop (Huawei calls it “security damage”).
  • unlock_code – historically a 16-digit decimal number stored in /dev/block/bootdevice/by-name/oeminfo at offset 0xA00.
  • Anti-rollback index – 4-byte integer in /productinfo; if current index < rollback index, device hard-bricks.
