The file usbloader.bin for the Huawei E5573s-320 is a critical utility used primarily for "unbricking" or flashing custom firmware on this specific mobile Wi-Fi router. Does it work?
Yes, it works, but its effectiveness depends entirely on using the correct version for your specific hardware revision. In the community of modem enthusiasts and developers, the usbloader.bin for the E5573s-320 is generally reviewed as reliable for the following tasks:
Forcing Download Mode: It allows the device to be recognized by a PC when it is stuck in a boot loop or "bricked" state.
Firmware Downgrading: It is often the first step in bypassing security restrictions to install "modded" firmware that allows for frequency locking or IMEI changes.
Unlocking: It is a standard tool used in the process of removing network provider locks. Technical Performance Review
Compatibility: This specific loader is tailored for the "s-320" variant. Using a loader meant for the "s-856" or "s-606" on an "s-320" will result in a failure to initialize the USB port.
Stability: Once the loader is successfully "pushed" to the device (usually via a tool like Balong USB Downloader), the modem enters a stable state where it can accept firmware files via fastboot or specialized flashing tools.
Ease of Use: It is not a plug-and-play file. It requires technical knowledge of:
The "boot shot" or "test point" method (physically shorting two pins on the motherboard to trigger recovery mode). Specific drivers (Huawei Mobile Connect drivers). Command-line or specialized GUI flashing tools. User Consensus
Users on technical forums like 4PDA and GSM-Forum report that while the file itself is functional, the primary "fail point" is often poor-quality USB cables or incorrect driver installation rather than the .bin file itself. Risks to Consider
Hardware Damage: If you use the "test point" method incorrectly, you can permanently short the board.
Permanent Brick: Flashing the wrong firmware after using the loader can lead to a "permanent brick" if the bootloader is locked or incompatible.
To prepare a "solid piece" for the Huawei E5573s-320 using a usbloader.bin

Here’s a concise, engaging story-style explanation of the E5573s-320 USB Loader.bin process — how it works, what it does, and why it matters for unlocking or debranding that particular 4G mobile WiFi router.
Title: The Silent Flash – Reviving the E5573s-320 via USB Loader.bin
In a small repair shop cluttered with routers and tangled cables, a technician named Mira held a Huawei E5573s-320. It was locked to a carrier — a digital cage.
“No web unlock option,” she muttered. “Firmware update loop.”
She’d tried every software trick: DC-Unlocker, Balong USB sniffers, even terminal commands. Nothing broke the lock.
Then she remembered the secret path — USB Loader mode.
Unlike normal boot, USB Loader mode bypasses the main firmware. It’s a low-level recovery state where the router expects a special binary: Loader.bin.
This isn’t a full firmware. It’s a tiny, 500 KB handshake — a digital skeleton key.
Here’s what Mira did:
Within minutes, the E5573s-320 rebooted — unlocked, debranded, breathing free.
Why Loader.bin works:
Huawei’s older Balong V7/V9 chips have a hidden USB loader protocol. The official firmware update process uses a signed Loader.bin. But modified loader binaries exist that skip signature checks, giving full flash read/write access — a backdoor for those who know the key.
The catch:
Wrong Loader.bin = hard brick. No recovery without JTAG.
Moral of the story:
The E5573s-320 isn’t just a locked box — it’s a vault with a secret loader door. But you need the right binary and steady hands to open it.
If you need the actual Loader.bin file or a safe flashing guide for your specific firmware version, let me know.
To get your Huawei E5573s-320 back up and running with a usbloader.bin file, you'll typically use a process called a "boot shot" or "test point" method. This is common for unbricking a device or fixing the "Error 19" issue during unlocking. Preparation & Requirements Possibly, if the BootROM is intact
Hardware: A screwdriver to dismantle the device and metal tweezers (or a wire) for the boot shot. Software:
Balong USB Downloader: The primary tool used to load the .bin file.
Drivers: Huawei Mobile Connect drivers (ensure the device shows as "3G PC UI Interface" in Device Manager). The File: A compatible usbloader.bin for the E5573s-320. Step-by-Step Guide
Dismantle the Device: Carefully remove the back cover and screws to access the motherboard. Perform the Boot Shot: Keep the battery inside but do not turn the device on.
Identify the boot pin (often the pin closest to the USB port) and the ground (metal casing of the USB port).
Use your tweezers to touch both the pin and the ground simultaneously while plugging the USB cable into your PC.
Verify Connection: Your PC should make a connection sound. Check Device Manager; it should recognize the device as Huawei Mobile Connect - 3G PC UI Interface or USB_COM. Load the usbloader.bin: Open the Balong USB Downloader. Click Detect to find the correct COM port.
Click the three dots (...) to select your usbloader.bin file.
Click Load. If successful, the progress bar will finish, and your device's LEDs may start blinking, indicating it is in download mode.
Finish Recovery: Once the loader is active, you can proceed to flash the desired firmware using standard Huawei flashing tools.
Note: Newer firmware versions may block older usbloader.bin files. If the loader fails immediately, ensure you have the specific file version compatible with your current firmware build.

The usbloader.bin file for the Huawei E5573s-320 is a specialized firmware component used to bypass software restrictions, such as network locks, or to recover a "bricked" device. It works by allowing the modem to enter a low-level download mode, typically after a physical "boot shot" (short-circuiting a specific pin to the ground), which enables the flashing of custom or downgraded firmware without standard security checks. How usbloader.bin Works
The core function of usbloader.bin is to serve as a bridge between the device's hardware and flashing software like the Balong USB Downloader.
Initialization: When the modem is in boot mode (detected as BOOT_3G), the loader file initializes the device's RAM to accept larger firmware files.
Permission Bypass: It is often used to resolve Error 19, a common issue where the standard update software rejects a firmware file because it doesn't match the current provider's signature.
Debranding and Unlocking: By loading this file, users can install "universal" or "openline" firmware that allows the modem to accept SIM cards from any carrier. Usage Process
Using usbloader.bin is a technical process that involves disassembling the modem.
Preparation: The modem is stripped to the motherboard to access the boot pin.
The Boot Shot: A metal tool, such as a tweezer or pin, is used to short the boot pin to the USB port's metal shield while connecting the USB cable to a PC.
Detection: If successful, the computer will detect the device under a COM port (e.g., Huawei Mobile Connect - 3G PC UI Interface).
Flashing the Loader: The Balong USB Downloader is used to select and "load" the usbloader.bin file.
Firmware Update: Immediately after the loader is flashed, the user can run the official firmware update software to install the desired OS version. Risks and Critical Notes
IMEI Loss: Flashing this file can sometimes damage the modem’s IMEI or dashboard information, requiring manual repair using AT commands like AT^CIMEI="[Your_IMEI]".
Compatibility: It is vital to use a loader file specifically designed for the E5573s series; using an incorrect version can lead to a hardware fault where the modem is stuck in emergency mode with no lights functioning.
Recovery Alternatives: For minor software issues, users should first attempt a factory reset using the physical reset button under the battery cover before resorting to low-level flashing.

Before diving into the flashing process, let’s understand the hardware.
With the usbloader.bin working, you can now:
In the context of Huawei modems, the "USB Loader" (usually a file named something akin to usbloader.bin or contained within a balong-usbdload package) is a piece of software code used to put the device into a Download Mode.
Think of it as a "bootstrap" or a temporary bootloader. When the modem is bricked or you need to overwrite the firmware completely, the standard operating system on the modem won't load. The USB Loader forces the device to accept new instructions via the USB port, allowing you to flash the NAND memory.
⚠️ Don’t just grab the first usbloader.bin you find. Get the one specific to E5573s-320, often labeled
usbloader_e5573s-320_v2.bin.
USBLoaderBin (USB loader binary) is a small file used to exploit or enable alternative firmware/boot methods on Huawei E5573s-320 mobile Wi‑Fi routers to allow unsigned firmware flashing or to enable advanced features (SSH, custom DHCP, SIM unlocking). This guide explains how to create and use a USBLoaderBin for the E5573s‑320 safely and practically.
Open a command prompt as Administrator:
balong-usbloader.exe -p COM3 -f usbloader.bin
(Replace COM3 with the actual COM port number of the Balong modem.)
