Xiaomi Secret Codes & USSD Dial Codes (2026)

MIUI / HyperOS engineering codes

Xiaomi secret codes cover both MIUI and the newer HyperOS builds, and the ecosystem is unusually generous with engineering access. The central entry point is the CIT hardware test suite, which walks through the display, touch panel, speakers, receiver, microphones, vibration motor, proximity and light sensors, gyroscope, cameras, Wi-Fi, Bluetooth and fingerprint reader in sequence, marking each subsystem pass or fail.

Alongside CIT, Xiaomi keeps standard Android diagnostic strings for battery and usage statistics, plus firmware and hardware version screens that tell you the exact ROM channel your device is running. That is useful before an update, a region switch or a bootloader unlock request, because Xiaomi's global, EEA, Indian and Chinese builds behave differently.

One warning specific to Xiaomi: several engineering menus on older MIUI versions expose write operations for the modem and calibration data. Reading values is harmless, but committing changes in those screens can degrade cellular performance in a way that only a full flash will repair. Stick to the codes marked safe on this page unless you are following manufacturer service documentation.

How to use Xiaomi codes

Open the Xiaomi 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.

Xiaomi secret codes — FAQ

Apakah semua ponsel Xiaomi mendukung kode rahasia yang sama?

Tidak. Dukungan kode bergantung pada model, versi firmware, dan dalam banyak kasus, operator yang menyediakan ponsel tersebut. Model Xiaomi 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 Xiaomi?

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 Xiaomi 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 Xiaomi?

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 Xiaomi saya?

Tekan *#06# pada ponsel GSM atau LTE apa pun, termasuk semua model Xiaomi, 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.
