[E5785Lh-22C] Bootpoint Short → Shows “Huawei Mobile Connect – Download Port” (Not 3G PC UI)

Question Summary
You are shorting the boot point on Huawei E5785Lh-22C, but Windows only detects **Huawei Mobile Connect – Download Port** instead of **Huawei Mobile Connect – 3G PC UI Interface**, and because of this, your unlock/flash tool does not recognize the device.

Feasibility Check
Possible – This is NORMAL behavior in bootpoint mode, not a fault.

Technical Explanation
When you short the boot test point on E5785Lh-22C:

• The HiSilicon Balong chipset is forced into **USB Download Mode**
• The modem **does NOT boot firmware**
• PC UI / AT interface is **disabled by design**
• Device exposes only:
- Huawei Mobile Connect – Download Port

So expecting **3G PC UI Interface** in bootpoint mode is incorrect.

Why Unlocker Does Not Detect It
Most “unlockers” work via:
• AT commands
• PC UI / Modem interface

But in **Download Port mode**:
• No AT commands
• No modem services
• Only low-level flashing is possible

That’s why unlocker tools fail to recognize it.

Correct Flashing Method (Step-by-Step)
To flash in this state, you must use **Download-mode compatible tools**:

✔ Required Tools
• Huawei USB Driver (latest)
• Balong USB Downloader / Huawei Downloader
• Correct E5785Lh-22C firmware (.bin / .xml based)

✔ Steps
1. Power off device
2. Short boot test point
3. Connect USB cable
4. Confirm Device Manager shows:
→ Huawei Mobile Connect – Download Port
5. Open Balong / Huawei Download Tool
6. Load correct firmware
7. Start flashing
8. After flash completes, disconnect
9. Power ON normally (no bootpoint)

After successful boot:
• PC UI Interface will return
• AT commands will work
• Unlocking tools can be used (if needed)

What Is NOT Possible
• You cannot get 3G PC UI while bootpoint is shorted
• You cannot unlock via AT-based tools in download mode

Pro Tip (Technician-Level Advice)
Always identify the MODE before choosing tools:

• Download Port → Flash only
• PC UI Interface → Unlock / AT / IMEI / NV

If device is soft-bricked but still shows PC UI:
• Avoid bootpoint
• Use AT-based repair first

After flashing, if PC UI does not appear:
• Check firmware region mismatch
• Reinstall Huawei drivers
• Use different USB port (USB 2.0 preferred)

Conclusion
Seeing **Huawei Mobile Connect – Download Port** during bootpoint shorting is 100% normal.
You need a **download-mode flashing tool**, not an unlocker.
