📌 Qualcomm All Protocols – Complete Theory
✅ Qualcomm chipset devices multiple communication protocols use karte hain jo flashing, unlocking, debugging, aur device control ke liye zaroori hain.
🔹 1. Qualcomm Protocols Overview
Qualcomm chipset wale devices different levels pe communication aur control ke liye multiple protocols use karte hain:
| Protocol Name | Purpose | Usage |
|---|---|---|
| ADB (Android Debug Bridge) | Debugging & Control | Software Modifications & App Debugging |
| Fastboot | Bootloader Control | Bootloader Unlocking & Firmware Flashing |
| EDL (Emergency Download Mode) | Low-Level Flashing | Device Unbrick & Factory Firmware Restore |
| Diag (Diagnostic Mode) | Modem & IMEI Repair | Network Unlock & Calibration |
| QFIL/QPST (Qualcomm Flashing Tools) | Full Firmware Flashing | Custom ROMs & Unbricking |
| Firehose Protocol | Secure Partition Access | Raw Flashing & Bootloader Bypass |
🔹 2. ADB (Android Debug Bridge) Protocol
📌 ADB ek command-line tool hai jo Android devices ko debug aur control karne ke liye use hota hai.
✅ Features & Uses:
✔️ USB Debugging ke zariye phone ko PC se connect karna.
✔️ FRP Remove, File Management, aur Log Checking.
✔️ Bootloader unlock aur EDL Mode access karna.
📌 Example Commands:
- Device check karne ke liye:
adb devices - EDL Mode me enter hone ke liye:
adb reboot edl
🔹 3. Fastboot Protocol
📌 Fastboot ek low-level protocol hai jo bootloader control aur partition flashing ke liye use hota hai.
✅ Features & Uses:
✔️ Bootloader Unlock aur Recovery Flashing.
✔️ System, Boot, aur Recovery Partition ko modify karna.
✔️ Factory Reset aur Partition Erase.
📌 Example Commands:
- Bootloader unlock karne ke liye:
fastboot oem unlock - Recovery mode flash karne ke liye:
fastboot flash recovery recovery.img
🔹 4. EDL (Emergency Download Mode) Protocol
📌 EDL Qualcomm devices ka ek emergency mode hai jo deep flashing aur boot repair ke liye use hota hai.
✅ Features & Uses:
✔️ Dead boot phones ko revive karna.
✔️ Secure Boot Bypass aur Full ROM Flashing.
✔️ QFIL ya UMT Tools ke zariye direct access.
📌 Connection Methods:
- Test Points Short Karke
- EDL Boot Cable
- ADB Command:
adb reboot edl - Fastboot to EDL Command:
fastboot oem edl
🔹 5. Diag (Diagnostic Mode) Protocol
📌 Diag Mode se Qualcomm devices ka modem aur NV data access kiya jata hai, jo network unlock aur IMEI repair ke liye zaroori hota hai.
✅ Features & Uses:
✔️ IMEI Repair aur Network Calibration.
✔️ NV Data Backup aur Restore.
✔️ Factory Network Lock Remove.
📌 Activation Methods:
- Secret Code Dial Kar Ke:
*#*#13491#*#* - ADB Command:
adb shell setprop sys.usb.config diag,adb
🔹 6. QFIL/QPST (Qualcomm Flashing Tools) Protocol
📌 QFIL (Qualcomm Flash Image Loader) aur QPST (Qualcomm Product Support Tool) Qualcomm devices ka firmware flash karne ke liye use hote hain.
✅ Features & Uses:
✔️ RawProgram.xml aur Patch.xml files se full ROM flashing.
✔️ Bootloader repair aur modem restore.
✔️ Non-secure aur Secure boot wale devices ko flash karna.
📌 Example Usage:
- QFIL Tool open karein.
- “Flat Build” mode select karein.
- Firehose Programmer (.mbn) file load karein.
- “Download” click karein.
🔹 7. Firehose Protocol
📌 Firehose ek Qualcomm flashing protocol hai jo secure partitions aur data flashing access deta hai.
✅ Features & Uses:
✔️ Full Firmware Flashing aur Partition Backup.
✔️ Secure Boot Bypass aur Raw Partition Modifications.
✔️ UMT, Miracle Box aur Hydra Tool ke saath kaam karta hai.
📌 Example Usage:
- Firehose ke zariye boot partition flash karne ke liye:
fastboot flash boot boot.img
📌 Conclusion
✔️ Qualcomm chipset wale devices multiple protocols ka use karte hain:
- ADB & Fastboot → Debugging aur Bootloader Control.
- EDL Mode → Emergency Flashing aur Unbrick.
- Diag Mode → IMEI Repair aur Modem Control.
- QFIL/QPST → Full Firmware Flashing.
- Firehose Protocol → Secure Boot Bypass aur Partition Access.
✔️ Har protocol ka apna importance hai aur har ek ka sahi tareeqa samajhna zaroori hai.
