📌 Qualcomm Diag Enable – Diagnostic Mode Activation
🔹 1. Qualcomm Diag Mode Kya Hai?
📌 Qualcomm Diagnostic Mode (Diag Mode) ek special mode hai jo phone ki NV (Non-Volatile) memory ko access karne ke liye use hota hai.
✔ IMEI Repair, SIM Unlock, Network Unlock, aur NV Data Backup ke liye ye mode zaroori hota hai.
✔ Ye mode QCN File Backup & Restore aur RF Calibration ke liye bhi use hota hai.
🔹 2. Qualcomm Diag Mode Enable Karne Ke Tareeqe
Different Qualcomm devices me Diag Mode enable karne ke multiple tareeqe hain:
✅ Method 1: ADB Command Se Enable Karna
Agar phone rooted hai ya USB Debugging enabled hai, to ADB Commands se DIAG mode enable kiya ja sakta hai.
🔹 Step-by-Step Process:
1️⃣ Phone me USB Debugging enable karein (Settings → Developer Options → Enable USB Debugging).
2️⃣ PC me ADB drivers aur platform tools install karein.
3️⃣ Command Prompt (CMD) open karein aur niche di gayi commands run karein:
adb shell
su
setprop sys.usb.config diag,adb
✅ Agar ye successfully execute ho jaye, to phone DIAG Mode me chala jayega aur Device Manager me “Qualcomm HS-USB Diagnostics” show hoga.
✅ Method 2: Secret Code Se Enable Karna (Non-Rooted Phones)
Kayi Qualcomm devices me secret dialer codes se DIAG mode enable kiya ja sakta hai.
🔹 Common Secret Codes:
📌 Samsung Qualcomm Devices:
*#0808# → DM + ACM + ADB Select karein → Reboot
📌 Xiaomi Qualcomm Phones:
*#9090# → DIAG Mode Select karein → Reboot
📌 Oppo / Vivo Qualcomm Phones:
*#8011# → USB DIAG Mode ON karein
✅ Agar code work kare, to “Qualcomm HS-USB Diagnostics” port show hoga.
❌ Agar code work na kare, to QPST ya ROOT method try karein.
✅ Method 3: Code Aurora Tweak (Root Required)
Agar phone rooted hai, to Code Aurora File modify karke DIAG mode enable kiya ja sakta hai.
🔹 Steps:
1️⃣ Root Explorer ya Terminal Emulator install karein.
2️⃣ Niche di gayi command execute karein:
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag_enable
✅ Phone DIAG Mode me chala jayega.
✅ Method 4: QPST Tool Se Enable Karna (EDL Mode Required)
Agar phone boot nahi ho raha ya USB Debugging disabled hai, to QPST ya QFIL Tool ka use karein.
🔹 Steps:
1️⃣ Phone ko EDL Mode (9008) me boot karein.
2️⃣ QPST Software Download karein aur “QPST Configuration” open karein.
3️⃣ Port section me “Qualcomm HS-USB QDLoader 9008” select karein.
4️⃣ Software Download / RF NV Manager se DIAG mode enable karein.
✅ Agar successful ho jaye, to phone Diagnostic Mode me enter ho jayega.
🔹 3. Check Karna Ke Qualcomm Diag Mode Enable Hua Ya Nahi?
1️⃣ Device Manager Open Karein
➡ Windows + R → devmgmt.msc → Enter
2️⃣ Ports (COM & LPT) Section Check Karein
✅ Agar “Qualcomm HS-USB Diagnostics (COM X)” show ho raha hai, to DIAG Mode enable hai.
❌ Agar show nahi ho raha, to method dobara try karein.
🔹 4. Qualcomm Diag Enable Na Ho To Kya Karein?
Agar Diag Mode enable nahi ho raha, to ye solutions try karein:
1️⃣ USB Debugging Ensure Karein – Developer Options me USB Debugging aur OEM Unlocking enable ho.
2️⃣ Different Codes Try Karein – Har model ke liye different codes ho sakte hain.
3️⃣ Drivers Reinstall Karein – Qualcomm QDLoader 9008 USB Drivers install karein.
4️⃣ QPST Tool Try Karein – Agar phone hard locked hai, to EDL Mode se QPST me enable karein.
5️⃣ Root + Terminal Method Try Karein – Agar phone rooted hai, to manual DIAG enable karein.
🔹 5. Summary – Qualcomm Diag Mode Complete Guide
📌 Qualcomm Diag Mode ka istemal IMEI Repair, QCN Backup/Restore, SIM Unlock aur Network Unlock ke liye hota hai.
✅ ADB Command Method (Rooted Phones ke liye Best)
✅ Secret Codes Method (Non-Rooted Phones me Work Kar Sakta Hai)
✅ Code Aurora Tweak (Agar Normal Methods Fail Ho Jayein)
✅ QPST / QFIL EDL Mode (Agar Boot Dead Ho Ya USB Debugging Off Ho)
Agar kisi specific Qualcomm device ka DIAG Mode enable karne ka issue hai, to model number bata dein, taake best solution provide kiya ja sake. 🚀
