The E5573s-320 is a great little router once freed from carrier limitations. The usbloader.bin method is the cheapest (free) way to unlock its full potential – but the devil is in the driver details and timing.
If you’re stuck, check your COM port number and try a different USB cable (data transfer capable, not just charging). Good luck.

The usbloader.bin file for the Huawei E5573s-320
is a specialized bootloader utility used to repair, unlock, or re-flash the device when standard firmware updates fail or the modem is "bricked". It is primarily a tool for technician-level maintenance rather than a consumer feature. Core Functions & Use Cases
Emergency Recovery: It allows the modem to enter a "Force Download" or "Boot Mode" when it is otherwise unresponsive.
Fixing Error 19: A common fix for "Error 19" (failed firmware flashing) which occurs when the device has a newer, locked firmware that prevents downgrading.
Unlocking: Essential for the "boot shot" method to unlock devices from specific carriers (like Smart Philippines) to accept any SIM card.
IMEI Repair: Facilitates access to low-level AT commands required to rewrite or fix a damaged IMEI. Operational Requirements
To use usbloader.bin successfully, the following environment is typically required:
Hardware Preparation: Often requires dismantling the device to "short" specific boot pins (the "boot shot" method) while connecting via USB.
Software Tools: Used in conjunction with tools like Balong USB Downloader and appropriate Huawei Modem Drivers.
Detection: Once the loader is correctly injected, the PC should detect the device as a specific COM port (e.g., BOOT_3G), allowing for new firmware installation. Standard Device Features (Post-Repair) Once the modem is operational, the E5573s-320 provides:
LTE Cat 4 speeds: Supports up to 150 Mbps download and 50 Mbps upload.
Multi-user Support: Connects up to 10 wireless users and 1 USB user simultaneously. e5573s320 usbloaderbin work
Portable Connectivity: Features a 1500mAh battery providing approximately 4–6 hours of active use.
Caution: Using usbloader.bin involves low-level hardware and software modification. Mistakes in this process can permanently disable (brick) the device.
This is a niche, technical topic centered on unbricking or unlocking the Huawei E5573s-320 mobile hotspot. To get the usbloader.bin working, a user typically needs to bypass standard firmware restrictions using a "boot pin" (test point) method.
The following blog post is designed for a tech-savvy DIY audience, focusing on troubleshooting the common "Error 19" and providing a clear sequence for using the loader file.
How to Fix Huawei E5573s-320: Unlocking & Error 19 Fix Guide
If you’ve tried to flash your Huawei E5573s-320 only to be met with the dreaded Error 19, you aren't alone. This happens because newer firmware versions are locked down by manufacturers to prevent unauthorized modifications.
To get your usbloader.bin to actually "work," you have to trick the device into a low-level download mode. 1. Preparation: The Gear You Need
Before starting, gather these essentials to avoid bricking your device permanently:
Huawei Mobile Drivers: Ensure your PC recognizes the device ports.
Balong USB Downloader: The primary tool used to push the loader file.
The Correct Loader: For this specific model, you need the usbloader.bin specifically compatible with the E5573s series.
Tweezers or a Paperclip: You’ll need these for the "boot shot" (short-circuiting the test point). 2. The "Boot Shot" Method (The Secret Sauce)
The reason your USB loader often fails is that the device is in the wrong mode. To force it into the correct state:
Dismantle the device: Carefully remove the back cover and battery.
Locate the Boot Pin: There is a specific contact point on the motherboard (often near the antenna ports) that must be grounded.
Short the Pin: Use your tweezers to touch the boot pin and the metal shield (ground) simultaneously. If you want, I can:
Connect to PC: While holding the short, plug in the USB cable. Your PC should make a "connected" sound, and you can release the short. 3. Loading the bin File
Once your device shows up in Device Manager as "Huawei Mobile Connect - DownLoad Port" (or similar), it's ready: Open the Balong USB Downloader tool. Select the detected COM port.
Click the "Load" button and select your e5573s_320_usbloader.bin.
If successful, the lights on your device might blink or change, signaling that the device has accepted the temporary bootloader and is ready for a firmware flash. 4. Troubleshooting Common Issues
Error 19 still appearing? This usually means the boot shot didn't "stick." Try the process again, ensuring the battery is removed or inserted according to your specific sub-model's requirements.
Device not detected? Check your drivers or try a different USB port. "Error 10: Find port failed" is a common driver-related headache. Final Word
Using a usbloader.bin is a powerful way to regain control of your E5573s-320, whether you're trying to use a different SIM card or repair a corrupted IMEI. Just remember: hardware modification carries risks. Always double-check your file versions before hitting "Start."
To prepare a "solid piece" for the Huawei E5573s-320 using a usbloader.bin
, you are likely performing an emergency recovery or unlocking procedure. This involves putting the device into Download Mode
(BOOT_3G) and loading the binary to allow for firmware flashing. Core Preparation Steps Enter Download Mode
Dismantle the device and keep the battery inside, but leave it powered OFF. Locate the
and ground it (short it to the board using a metal wire or needle) while connecting the USB cable to your PC.
If successful, your PC should detect a new COM port, typically labeled as "HUAWEI Mobile Connect - DownLoad Port" in Device Manager. Use a "Safe" Loader It is highly recommended to use a usblsafe.bin rather than the original usbloader.bin
Original loaders from Huawei may erase the NAND flash entirely, which can wipe your unique device data like , Serial Number, and radio calibration.
"Safe" loaders are patched to disable this erasure procedure, keeping your factory data intact while allowing the flash. Execute the Load Open a tool like the Balong USB Downloader (balong-usbdload). Select the correct
file for the E5573s-320 (often compatible with E5573s-606 files). Related search terms supplied
Click "Load" to send the binary to the device. Once the loader is active, you can proceed to flash the actual firmware using a tool like balongflash Related Resources & Tools
