Qualcomm All Protocols – Complete Theory
✅ Qualcomm chipset wale devices multiple communication protocols use karte hain jo flashing, unlocking, debugging, aur device control ke liye zaroori 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 |
📌 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:
adb devices
adb reboot edl
📌 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:
fastboot oem unlock
fastboot flash recovery recovery.img
📌 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
📌 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
📌 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.
📌 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, Hydra Tool ke saath kaam karta hai.
Example Usage:
fastboot flash boot boot.img
- ADB & Fastboot: Debugging aur bootloader control.
- EDL Mode: Emergency flashing aur unbrick.
- Diag Mode: IMEI repair aur NV data access.
- QFIL/QPST: Full firmware flashing.
- Firehose Protocol: Secure boot bypass aur partition access.
Har protocol ka apna importance hai, aur inka sahi istemal Qualcomm devices ke proper functioning ke liye bohot zaroori hai.
