📌 Qualcomm Diag Mode Practical – Step-by-Step Guide
⚡ Qualcomm Diag Mode practical ka istemal IMEI Repair, SIM Unlock, Network Unlock aur QCN Backup/Restore ke liye hota hai.
✅ Is practical me hum Qualcomm Diag Mode enable karna, port check karna, aur IMEI/QCN repair ke liye use karna seekhenge.
🔹 1. Qualcomm Diag Mode Enable Karne Ka Practical
✅ Method 1: ADB Commands (Rooted Phones ke liye Best)
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 Phone ko PC se connect karein aur Command Prompt (CMD) open karein.
4️⃣ Niche di gayi commands run karein:
adb shell
su
setprop sys.usb.config diag,adb
✅ Agar command successfully execute ho jaye, to phone DIAG Mode me chala jayega.
➡ Device Manager me “Qualcomm HS-USB Diagnostics” (COM Port) 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.
📌 Steps:
1️⃣ Phone dialer open karein aur secret code enter karein.
🔹 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
2️⃣ Phone restart karein aur Device Manager me port check karein.
✅ Agar “Qualcomm HS-USB Diagnostics” (COM Port) show ho raha hai, to DIAG Mode enable ho gaya.
✅ Method 3: 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.
➡ (Volume Up + Volume Down + USB Connect)
2️⃣ PC me QPST Tool install karein aur open karein.
3️⃣ QPST Configuration → Ports → Add Port karein.
4️⃣ “Qualcomm HS-USB QDLoader 9008” select karein.
5️⃣ Software Download / RF NV Manager se DIAG mode enable karein.
✅ Agar successful ho jaye, to phone Diagnostic Mode me enter ho jayega.
🔹 2. 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.
🔹 3. Qualcomm Diag Mode Se IMEI Repair Practical
✅ IMEI Repair karne ke liye QPST Tool ka use karna hoga.
📌 Steps:
1️⃣ QPST Tool Download karein aur install karein.
2️⃣ Phone ko DIAG Mode me connect karein aur QPST open karein.
3️⃣ Software Download Section open karein.
4️⃣ “Backup NV Data” ka option select karein aur backup save karein.
5️⃣ IMEI Repair Tool open karein aur new IMEI enter karein.
6️⃣ “Write” button click karein aur process complete hone ka wait karein.
✅ Agar process successfully complete ho jaye, to phone restart karein aur IMEI check karein.
🔹 4. Qualcomm Diag Mode Se QCN Backup & Restore Practical
QCN File ka Backup & Restore Qualcomm phones me network issues fix karne ke liye zaroori hota hai.
📌 Steps:
1️⃣ QPST Software Open karein.
2️⃣ Service Programming → “Read From Phone” ka option select karein.
3️⃣ Phone ki QCN File save karein.
4️⃣ Agar phone me network issue ho, to saved QCN File ko restore karein.
✅ Agar process successfully complete ho jaye, to phone restart karein aur network check karein.
🔹 5. Qualcomm Diag Enable Na Ho To Kya 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.
🔹 Summary – Qualcomm Diag Mode Complete Practical
📌 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)
✅ QPST / QFIL EDL Mode (Agar Boot Dead Ho Ya USB Debugging Off Ho)
✅ IMEI Repair aur QCN Restore Practical Steps
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. 🚀
