Huawei Secret Codes & USSD Dial Codes (2026)

EMUI / HarmonyOS codes

Huawei secret codes span both EMUI and HarmonyOS builds and are aimed squarely at hardware verification. The project menu is the main tool: it groups an automatic full-device test with individual checks for the screen, touch panel, receiver, speaker, microphones, cameras, sensors, vibration motor and charging circuitry, then prints a pass or fail summary you can screenshot.

Huawei also exposes firmware, software and hardware version screens. These are more important on Huawei hardware than most, because devices sold in different regions carry different firmware branches, and knowing your exact build number determines which official update packages will install at all.

Because recent Huawei devices ship without Google Mobile Services, some generic Android diagnostic strings behave differently or are absent entirely. Codes in the diagnostic and info categories below are read-only and safe to try; anything marked destructive triggers a data wipe as soon as it is entered, with no confirmation and no recovery path.

How to use Huawei codes

Open the Huawei dialer and go to the keypad, exactly as if you were dialling a number.
Type the code precisely as shown, including the leading * and the trailing #. Autocorrect and paste can drop characters, so type it out.
Most sequences fire the moment the final character is entered — you usually do not press call.
If the screen does not change, press the call button once; a few USSD strings need it.
Back up photos, messages and app data before running anything marked destructive, then confirm you are on the right device.
Nothing at all happening usually means the code is disabled on your firmware or blocked by your carrier — it is not a fault with your handset.

Huawei secret codes — FAQ

Apakah semua ponsel Huawei mendukung kode rahasia yang sama?

Tidak. Dukungan kode bergantung pada model, versi firmware, dan dalam banyak kasus, operator yang menyediakan ponsel tersebut. Model Huawei lama sering kali menyediakan akses ke lebih banyak menu servis dibandingkan model terbaru, karena produsen secara bertahap membatasi akses ke alat rekayasa hanya melalui aplikasi diagnostik yang ditandatangani secara digital. Jika suatu kode tidak memberikan respons, hampir bisa dipastikan kode tersebut telah dihapus atau dinonaktifkan pada versi sistem Anda, bukan karena salah diketik.

Apakah aman menggunakan kode rahasia Huawei?

Kode yang kami tandai sebagai "aman" hanya menampilkan informasi atau membuka menu pengujian yang hanya dapat dibaca, sehingga tidak dapat merusak ponsel Anda. Kode bertanda "hati-hati" mengubah pengaturan atau menjalankan prosedur perangkat keras yang perlu Anda pahami terlebih dahulu, sedangkan kode bertanda "destruktif" langsung menghapus data pengguna tanpa dialog konfirmasi. Selalu cadangkan data sebelum menjalankan apa pun dalam kategori destruktif.

Mengapa tidak terjadi apa-apa saat saya memasukkan kode?

Ada tiga alasan umum: kode tersebut tidak didukung oleh firmware Anda, operator jaringan Anda telah memblokir rangkaian kode USSD tersebut, atau aplikasi telepon mengharuskan Anda menekan tombol panggil untuk rangkaian kode itu. Coba kode tersebut dengan SIM lain atau dalam mode pesawat, dan pastikan setiap karakternya benar, termasuk tanda bintang di awal dan tanda pagar di akhir.

Apakah penggunaan kode-kode ini akan membatalkan garansi Huawei saya?

Sekadar membaca informasi diagnostik tidak membatalkan garansi. Namun, mengubah pengaturan pita frekuensi radio, menjalankan operasi penulisan di menu teknis, atau melakukan format pabrik dapat membuat perangkat Anda berada dalam kondisi yang mungkin dianggap pusat servis sebagai akibat tindakan pengguna. Gunakan hanya kode yang bersifat baca-saja, kecuali Anda mengikuti panduan perbaikan resmi.

Apakah kode ini bisa membuka kunci jaringan pada ponsel Huawei?

Tidak. Membuka kunci jaringan memerlukan kode pembuka kunci yang diterbitkan operator atau permintaan pembukaan kunci resmi melalui operator Anda. Situs mana pun yang menjanjikan kode panggilan universal gratis untuk membuka kunci berarti menyesatkan Anda. Kode yang tercantum di sini hanya menampilkan diagnostik, status jaringan, informasi perangkat tegar, dan prosedur pengaturan ulang pabrik.

Bagaimana cara menemukan IMEI pada perangkat Huawei saya?

Tekan *#06# pada ponsel GSM atau LTE apa pun, termasuk semua model Huawei, dan IMEI akan langsung muncul. Anda juga dapat memvalidasi nomor tersebut dengan pemeriksa IMEI kami, yang menjalankan perhitungan jumlah periksa Luhn yang digunakan GSMA untuk mendeteksi nomor IMEI yang salah ketik atau dibuat-buat.
