Title: e5573s-320 USBloader.bin hot — Quick Guide & Working Files
Overview
- Device: Huawei e5573s-320 (firmware 21.x / 22.x series)
- Goal: Use a modified USBloader.bin ("hot") to enable USB tethering / dashboard bypass and keep the device online after inserting a USB stick or using as a USB modem.
- Compatibility: Specific to e5573s-320; may work on similar e5573 variants but follow device-specific steps.
Important notes
- Flashing or modifying firmware can brick the device and may void warranty.
- Use only files from trusted sources and verify checksums.
- This post assumes familiarity with basic modem flashing, ADB/USB drivers, and Windows environment. Adjust for macOS/Linux accordingly.
Files included (expected)
- USBloader.bin (hot) — modified loader to enable persistent USB mode
- backup_fw.bin — original firmware backup (always keep one)
- flash_tool.exe or compatible flasher (e.g., Huawei Update Extractor + fastboot/boot tools)
- README.txt with SHA256 checksums and restore instructions
Preparation
- Charge battery to ≥50% and keep cable connected during process.
- Backup current firmware/config:
- Use the device’s web UI to export settings where available.
- Use flash tool or extraction method to save the original firmware to backup_fw.bin.
- Install drivers:
- Huawei HiLink / Mobile Partner drivers or universal CDC/Ethernet drivers.
- If using ADB/fastboot approach, install ADB drivers.
Procedure (Windows example)
- Put device into flashing mode:
- Power off the device fully.
- Connect USB cable to PC and device.
- Press/hold reset or the appropriate button combo (varies by model) to enter loader mode. If uncertain, try powering on while holding WPS or reset for ~10s.
- Launch flasher:
- Open flash_tool.exe (run as Admin).
- Select the modified USBloader.bin as the firmware/loader to flash.
- Select the target device (e5573s-320).
- Flash the loader:
- Click Start/Download. Wait until the tool reports success.
- Do not disconnect during flashing.
- Verify:
- After flashing, the device should expose USB tethering/network interface automatically when connected.
- Check Windows Network Connections for a new mobile broadband or RNDIS/Ethernet device.
- Open browser to 192.168.8.1 (or device IP) to confirm dashboard access, if present.
Post-flash tweaks
- If USB mode doesn’t persist after reboot:
- Reflash loader with alternative build or try adjusting configuration in the web UI (if available).
- To restore original firmware:
- Use flash_tool.exe to flash backup_fw.bin or follow restore steps in README.
Troubleshooting
- Device not recognized:
- Reinstall drivers, try different USB port/cable, use USB 2.0 port.
- Flasher fails:
- Ensure correct loader file and model match; try different flashing tool or run as Admin.
- Bricked device:
- Attempt emergency restore using original firmware and loader in recovery/boot mode. If unsuccessful, professional repair may be required.
Safety & legal
- Only use on devices you own.
- Modifying firmware can violate provider terms of service; proceed at your own risk.
Hashes & Verification
- Always verify SHA256/MD5 of downloaded files against provided checksums in README before flashing.

6. Hardware Variations (Crucial Warning)
The Huawei E5573 series has multiple hardware revisions (e.g., E5573s-156, E5573s-320, E5573s-606).
- Incompatibility: A USB Loader binary designed for the -156 revision will almost certainly brick a -320 revision device. The search term "hot" implies a version specifically known to work on the s-320, but verification is difficult.
- Board Identification: Users are advised to disassemble the device and verify the board ID before attempting to flash via the USB Loader method.

Prerequisites
- Windows PC (Windows 7 or 10 recommended, driver signature enforcement disabled).
- Micro USB Cable (Data sync capable – not a charge-only cable).
- Huawei Balong Flash Tool (Version 1.0.0.7 or newer).
- The correct

Scenario 1: The Stuck Boot Loop (Red Light Flashing)
The device powers on, the red light flashes 3 times, and then it dies. The WebUI at 192.168.8.1 is unreachable. The standard update.bin placed on a microSD card fails to install. You need the "hot" loader to force a factory firmware via USB.
