The Huawei E5573s-320 is a versatile 4G LTE mobile Wi-Fi hotspot, but users often face "Error 19" or bricked states when attempting to unlock or update it. The usbloader.bin file is the essential "hot" fix for these issues, serving as a universal bootloader that allows your computer to communicate with the modem when it is stuck in download mode. What is USBLoader.bin?
The usbloader.bin is a small binary file used during the "Shot Boot" or "Test Point" method. When a modem has a high-security firmware version that blocks standard updates, this file "bridges" the connection, allowing you to flash older or modified firmware to bypass carrier locks. Essential Tools for the Process
To use the usbloader.bin effectively, you will need several specialized tools:
Balong USB Downloader: The primary software used to flash the .bin file to the device.
Huawei Mobile Connect Drivers: Specifically the "3G PC UI Interface" driver to ensure your PC recognizes the modem.
Firmware Files: Often version 21.110.99.02.00 or similar universal versions are used to restore the device.
Physical Tools: A small pin, tweezers, or wire to perform the "boot shot" on the motherboard. Step-by-Step Recovery and Unlocking Guide
This "hot" method is typically used for unbricking or deep unlocking that standard software cannot handle.
Prepare the Hardware: Disassemble the modem to expose the motherboard. Locate the boot pin—a specific copper point on the board near the USB connector. Enter Emergency Download Mode:
Place a pin or tweezers to "short" the boot pin to the ground (often the USB metal shield).
While holding the short, connect the modem to your PC via USB.
If successful, your PC should detect a new device under COM ports as "Huawei Mobile Connect - 3G PC UI Interface" or "BOOT_3G". Flash the USBLoader: Open the Balong USB Downloader as an administrator.
Select the correct COM port and browse for your usbloader.bin file.
Click "Load." The lights on the modem may remain off, but the software will show a progress bar.
Install Firmware and Web UI: Once the loader is active, the modem is ready to accept a new firmware package. Run the firmware update tool to install a "universal" firmware that removes carrier restrictions.
Finalize with Web UI: After the firmware, install the Web UI file to restore the browser-based dashboard for managing your Wi-Fi settings. Important Precautions
IMEI Repair: Flashing these files can sometimes "zero out" your IMEI. You may need to use AT commands like AT^CIMEI="Your_IMEI" to restore it.
Version Compatibility: Ensure you use the usbloader.bin specifically intended for the E5573s series, as using one for a different model (like the E5573cs) can permanently brick the device.
For users who just need a simple reset without hardware tampering, a hard reset can be performed by holding the reset button under the battery for 10 seconds.
The phrase "e5573s320 usbloaderbin hot" typically refers to a critical file (usbloader.bin) used for the Huawei E5573s-320 mobile hotspot. This file is essential for "bootshotting"—a technical recovery or unlocking process that forces the device into a low-level "USB Download" mode to bypass firmware restrictions or repair a "bricked" (non-functional) unit. The Technical Anatomy of a Firmware Recovery
The process of revitalizing a Huawei E5573s-320 involves bridging the gap between hardware failure and software recovery. When a modem becomes unresponsive or locked to a specific carrier, standard software updates often fail, resulting in "Error 19" or a device that won't power on. 1. The Hardware Trigger: "Bootshot"
The first stage requires physical intervention. By disassembling the device and using a metal tool like tweezers to connect a specific "boot pin" on the motherboard to the ground (often the USB casing), the user bypasses the standard boot sequence. When plugged into a PC in this state, the computer identifies the device as a raw interface, typically labeled as "Huawei Mobile Connect - 3G PC UI Interface" or "BOOT_3G". 2. The Software Bridge: usbloader.bin
Once the hardware is primed, the usbloader.bin file acts as a temporary operating system. Using specialized tools like the Balong USB Downloader, this binary file is "injected" into the modem's RAM.
Function: It initializes the hardware and opens communication ports (FC ports) that allow for deeper data transfer. e5573s320 usbloaderbin hot
Sensitivity: Using the wrong version of usbloader.bin can permanently brick the device, especially if the modem has a newer firmware version with enhanced security signatures. 3. The Final Restoration: Firmware and WebUI
With the loader active, the device is ready for its permanent software. This is a multi-step sequence:
Modem Firmware: The core operating system (e.g., version 21.x) that handles signal processing and cellular connections.
Web UI: The graphical interface (e.g., version 17.x) that allows users to manage settings via a browser.
IMEI Repair: If the identification numbers were corrupted during a crash, specialized AT commands are sent through the open ports to restore the device’s identity. Risks and Safety Considerations
Flashing a modem is a high-stakes procedure. A power interruption or using a file meant for a different sub-model (like the E5573Cs-322) can result in a "half-dead" state where the device turns on but refuses to connect to any network. Essential Tools for the Task

(BOOT_3G). It is used when the device is "soft-bricked" or locked to a specific carrier. Primary Use Cases Unlocking Restrictions
: Bypassing carrier locks (e.g., Smart Philippines, MTN Zambia) to allow the use of any SIM card. Fixing Error 19
: Resolving firmware flash errors (specifically Error 19) that occur when the device rejects a new firmware version. Repairing Bricked Devices
: Reviving modems that are stuck in a bootloop or showing no lights by forcing them into a state where new firmware can be written. The "Boot Shot" Procedure
To use the loader, users typically perform a "boot shot" or "test point" method: Disassembly
: The modem back cover is removed to expose the motherboard. Shorting Pins
: A metal object (like tweezers) is used to short a specific boot pin to the ground while connecting the device to a PC via USB. Loading the Binary : Once the PC detects a "BOOT_3G" COM port, tools like Balong USB Downloader are used to send the usbloader.bin file to the device. Firmware Restoration
: After the loader is successful, the device enters a state where a universal or downgraded firmware can be installed. Critical Risks & Compatibility Firmware Mismatch : Using the wrong usbloader.bin
(e.g., one meant for the E5573Cs instead of the E5573s) can permanently brick the device.
: Flashing universal firmware via this method often resets the IMEI to 000000000000000
, requiring additional repair tools to restore the original identification number.
: Opening the device and shorting pins immediately voids the manufacturer's warranty.
