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
هل تدعم جميع هواتف Xiaomi الرموز السرية نفسها؟
لا. يعتمد دعم الرموز على الطراز وإصدار البرنامج الثابت، وفي كثير من الحالات على شركة الاتصالات التي وفّرت الهاتف. غالبًا ما تتيح طرازات Xiaomi القديمة قوائم خدمة أكثر من الإصدارات الأحدث، لأن الشركات المصنّعة تقيّد تدريجيًا الوصول إلى الأدوات الهندسية بتطبيقات تشخيص موقّعة. إذا لم يفعل الرمز شيئًا، فمن شبه المؤكد أنه أُزيل أو عُطّل في إصدار نظامك، وليس أنك أدخلته بشكل خاطئ.
هل من الآمن طلب الرموز السرية لهواتف Xiaomi؟
الرموز التي نصنّفها «آمنة» تعرض المعلومات فقط أو تفتح قائمة اختبار للقراءة فقط، لذا لا يمكنها إتلاف هاتفك. أما الرموز المصنّفة «تتطلب الحذر» فتغيّر إعدادًا أو تبدأ إجراءً على المكوّنات ينبغي أن تفهمه أولًا، والرموز المصنّفة «مدمّرة» تمسح بيانات المستخدم فورًا دون نافذة تأكيد. أنشئ دائمًا نسخة احتياطية قبل تشغيل أي رمز من الفئة المدمّرة.
لماذا لا يحدث شيء عند إدخال رمز؟
هناك ثلاثة أسباب شائعة: الرمز غير مدعوم في برنامجك الثابت، أو مشغّل الشبكة حظر سلسلة USSD، أو تطبيق الاتصال يتطلب الضغط على زر الاتصال لهذا التسلسل تحديدًا. جرّب الرمز باستخدام بطاقة SIM مختلفة أو في وضع الطيران، وتأكد من كل محرف، بما في ذلك النجمة في البداية وعلامة المربع في النهاية.
هل يؤدي استخدام هذه الرموز إلى إبطال ضمان Xiaomi؟
مجرد قراءة معلومات التشخيص لا يُبطل الضمان. لكن تغيير إعدادات نطاقات الاتصال اللاسلكي، أو تنفيذ عمليات كتابة في قائمة هندسية، أو إجراء تهيئة المصنع قد يترك جهازك في حالة يعتبرها مركز الخدمة ناتجة عن المستخدم. التزم برموز القراءة فقط ما لم تكن تتبع إرشادات إصلاح رسمية.
هل يمكن لهذه الرموز إلغاء قفل الشبكة لهاتف Xiaomi؟
لا. يتطلب إلغاء قفل الشبكة رمز إلغاء قفل تصدره شركة الاتصالات أو طلبًا رسميًا عبر مشغّلك. أي موقع يعدك برمز اتصال مجاني وشامل لإلغاء القفل يضللك. الرموز المدرجة هنا تتيح فقط التشخيص وحالة الشبكة ومعلومات البرنامج الثابت وإجراءات إعادة ضبط المصنع.
كيف أعثر على IMEI في جهاز Xiaomi؟
اطلب *#06# على أي هاتف GSM أو LTE، بما في ذلك جميع طرازات Xiaomi، وسيظهر IMEI فورًا. يمكنك أيضًا التحقق من الرقم باستخدام أداة فحص IMEI لدينا، التي تطبّق المجموع الاختباري بخوارزمية لون الذي تستخدمه GSMA لاكتشاف أرقام IMEI المدخلة خطأً أو المختلقة.
