The usbloader.bin file is a critical low-level tool used to force the device into a mode where new firmware can be flashed, especially when standard updates fail due to "Error 19" (a digital signature mismatch) . The "Bootshot" Hack: Reviving the E5573s-320
If you are dealing with a "hot" or difficult-to-flash device, here is the technical breakdown of how professionals use the usbloader.bin file:
Entering Download Mode (The Bootshot): Standard software often can't communicate with a locked device. Users must dismantle the router and perform a "bootshot"—physically shorting a specific pin on the motherboard to the ground (usually the metal USB casing) using tweezers or a wire while plugging it into a PC .
The Role of Balong USB Downloader: Once shorted, the PC detects a new COM port (often labeled "BOOT_3G"). You then use a tool called Balong USB Downloader to send the usbloader.bin file to the device . This file act as a temporary operating system that "unlocks" the device's memory for writing .
The "Hot" Modification: Many "modded" firmware versions (often shared in forums like Hovatek) allow for de-branding, changing the IMEI, or enabling the device to work with any SIM card . Critical Warning
Using an incorrect usbloader.bin or flashing the wrong firmware can permanently "brick" the device. For example, some Pakistani Zong Bolt firmware versions write an "anti-downgrade bit" that makes further modifications impossible .

usbloader.bin file for the Huawei E5573s-320 is a specialized piece of code used to put the device into Download Mode
(Force Download) for unlocking or fixing bricked firmware. Because this is a proprietary binary file, its "full text" cannot be accurately represented as standard readable text, but rather as hexadecimal data or a compiled binary structure. Understanding the usbloader.bin
: It is a bootloader patch that initializes the hardware (Balong chipset) to accept new firmware images. Version Sensitivity
: Recent firmware versions (like version 328) often block older loaders, leading to errors during the flashing process. Flashing Requirement
: To use it, you typically need to "boot shot" the device by short-circuiting specific pins on the motherboard while connecting it to a PC via USB. Common Recovery/Unlocking Steps
If you are looking for the "full process" to use this loader, standard community procedures usually follow this order: Preparation : Install necessary Huawei Modem Drivers and download the specific firmware for the E5573s-320 Force Download Mode : Disassemble the unit and perform a This topic relates to the specialized technical process
(connecting the boot pin to ground) while plugging in the USB cable. Loading the Binary : Use software like Balong USB Downloader to send the usbloader.bin to the device. Firmware Update
: Once the device is recognized as a COM port (often "3G PC UI Interface"), you can flash a universal firmware to unlock the device or fix "Error 19". Important Precautions Bricking Risk

This report outlines the status, technical requirements, and troubleshooting procedures for the Huawei E5573s-320
mobile hotspot, specifically regarding the "usbloader.bin" file used during firmware flashing or unlocking procedures. 1. Technical Overview Huawei E5573s-320 is a portable 4G LTE mobile Wi-Fi router. The usbloader.bin
file is a critical "bootloader" or "loader" file used when the device is in Force Download Mode
(often triggered via a "test point" on the motherboard). This file allows a PC to communicate with the device's HiSilicon chipset to write new firmware or unlock the SIM. 2. Critical Requirements for Flashing
To successfully use a loader on this device, the following environment must be established: Huawei USB Drivers:
must be installed so the PC recognizes the device as "Huawei Mobile Connect - PC UI Interface." Force Download Mode:
This is typically achieved by short-circuiting a specific "test point" to the ground on the PCB while connecting the USB cable. Loader Compatibility: usbloader.bin must match the specific hardware version of the E5573s-320 Corrupted or missing loader
(often based on the Hi6921 chipset) to avoid bricking the device. 3. Common Issues & Troubleshooting
If the device is unresponsive or showing a red light, consider the following status indicators and fixes: Steady Red Light:
This usually indicates a lack of internet connection, a failed update, or a firmware error. Device Not Detected:
Ensure "USB Debugging" or the correct COM port is active in your flashing tool. Resetting to Defaults:
If the device is functional but locked, a factory reset can be performed by holding the physical reset button under the back cover for several seconds. Web Interface Access: The default management page is typically found at

No. The USBLoaDerBin is a diagnostic and repair tool, not an everyday driver. Once you have successfully flashed your factory firmware or an unbranded version, you should never need the loader again.
Using the "hot" loader erases the modem_st1 and modem_st2 partitions (where carrier locks are stored). If you flash it incorrectly, your IMEI may become zero (null), rendering the device unable to register on any cellular network.
