The firmware is tied to the baseband chip (e.g., MDM9207 vs. RDA8910). Flashing to different hardware will permanently destroy the device.
There are two primary ways to update this firmware: through the web interface or via a dedicated update tool. Method 1: Via Web Interface (If supported) Plug the 4gdong001 into your computer.
Even with careful flashing, problems can occur. Here are the top five issues and solutions.
While the 4GDONG001 firmware is designed to be reliable and efficient, there are some common issues that users may encounter. Some of these issues include: 4gdong001 Firmware

The device can be used in "USB Dongle Mode". In this mode, the dongle acts purely as a modem connected via USB. The user's lsusb output showed the modem as ID 05c6:6000 Qualcomm, Inc. . This is a common identifier for Qualcomm-based modems that often use the standard qmi_wwan or option kernel drivers.
Modern 4G dongles, particularly those with voice support, use firmware to handle VoLTE (Voice over LTE) calls and SMS messages, often accessible through a web interface or USB AT commands. | Specification | Details | | :--- |
Many of these sticks are sold with "WiFi" capability. If your stick has a chipset, it is actually a small Android computer.
The 4G speed depends on network coverage. The 4GDONG001 is generally "unlocked", meaning it should work with SIM cards from various carriers, though you should always verify compatibility with your local network bands before purchasing.
Here are typical issues and solutions for the 4GDONG001:
