The Upgrade
It was a typical Monday morning for John, a electronics enthusiast and owner of a DSO2512G digital oscilloscope. As he sipped his coffee, he checked his email and found a notification from the manufacturer, Rigol, about a new firmware update for his device. The email mentioned that the new firmware, version 2.5, included several bug fixes, new features, and improvements to the user interface.
Intrigued, John decided to upgrade his oscilloscope's firmware. He navigated to the Rigol website, downloaded the firmware file (DSO2512G_V2.5.0.FW), and extracted it to his computer.
The instructions provided by Rigol were straightforward: connect the oscilloscope to the computer using a USB cable, turn on the device, and then run the firmware update tool. John carefully followed the steps:
The update process took a few minutes, during which the oscilloscope's display flickered and the device restarted several times. John anxiously waited, hoping that the update would be successful. Now comes the nerve-wracking part
The Unexpected Glitch
Just as the update was almost complete, John's computer suddenly froze, and the firmware update tool crashed. The oscilloscope's display went blank, and John was left staring at a puzzled screen.
"No, no, no!" John exclaimed, frustrated by the sudden interruption. He rebooted his computer and tried to run the firmware update tool again, but this time, the oscilloscope didn't seem to be recognized.
Panicked, John searched online for solutions, but none seemed to work. He began to worry that he might have damaged his oscilloscope.
The Solution
After some trial and error, John stumbled upon a forum post from another DSO2512G user who had encountered a similar issue. The user suggested trying to update the firmware using a different USB port or a USB hub.
John tried connecting the oscilloscope to a different USB port, and to his relief, the firmware update tool recognized the device again. He re-ran the update process, and this time, it completed successfully.
The DSO2512G's display flickered back to life, and John was greeted with the new firmware version 2.5. He was thrilled to explore the new features and improvements.
The Takeaway
John learned a valuable lesson about backing up his work and ensuring a stable connection during critical updates. He was also impressed by the online community's willingness to help and share knowledge.
From then on, John made sure to regularly check for firmware updates and was more cautious when performing critical operations. His DSO2512G oscilloscope continued to serve him well, and he enjoyed exploring the new capabilities offered by the updated firmware.

oscilloscope, you can find the latest official and modified community firmware on forums like EEVblog. Users often share updated .bin files for different PCB revisions (e.g., V9.1 or V10.1). Preparation & Requirements
Identify Your Hardware: Check your PCB version (printed inside or shown in the menu) and current firmware version before downloading an update.
Driver Setup: For direct flashing via a PC, you will likely need the WinUSB driver installed through Zadig.
Tools: You may need sunxi-fel.exe to read/write to the SPI flash chip. Installation Steps
Updating typically involves entering USB FEL mode so your computer can talk to the device:
Enter Boot Mode: One common method involves holding a specific pin (like pulling the SPI flash CS pin to ground with a resistor) while powering on, or holding the power button while off to enter a boot loop. Connect to PC : Use a high-quality USB cable to connect the to your computer.
Flash Firmware: Use a flashing tool or the command line (sunxi-fel) to write the new .bin file to the device. A full flash typically takes about 45 seconds. Release: Once you see activity indicating a file
Verify: Once finished, restart the device and check the "About" or "System" menu to confirm the new version number. Important Tips
Modified Firmware: Community-modified versions like the ZeeTweak or modified V1.3.0C can unlock features like cursors for screenshots and fixed voltage calculations.
FPGA Updates: If you upgrade to certain versions (like V1.3.0C), you may also need to update the FPGA firmware to avoid "AUTO" button issues.
Backup First: It is highly recommended to "dump" (copy) your original firmware using the flashing tool before applying any updates in case you need to revert.

is a popular handheld oscilloscope, but its stock firmware can sometimes have bugs, such as issues with the NORM trigger mode. Updating or installing custom firmware like ZeeTweak can unlock new features, including cursor measurements for screenshots, waveform CSV generation, and improved UI elements. Prerequisites for Installation Before starting, ensure you have the following:
A Windows PC: Most flashing tools for this device are designed for Windows. Micro-USB Data Cable
: Use a high-quality cable to ensure a stable connection during the flash process. WM Upgrade Tools: The uses a Winner Micro chip (W80X series).
Firmware File: A valid .fls file (official or modified like ZeeTweak). Step-by-Step Firmware Installation Guide 1. Prepare the Software Download and extract the WM Upgrade Tools to your PC.
Launch the application. If the interface is in Chinese, click the third option in the top-left menu to change the language to English. 2. Configure the Flashing Tool Set the Chip type to W80X.
Click the path or "Open" button to select your downloaded firmware .fls file. 3. Put the into Flash Mode Ensure the device is powered OFF.
Press and hold the Power button on the oscilloscope. This enables the internal serial port for flashing.
Connect the device to your PC via USB while continuing to hold the Power button. 4. Execute the Flash In the WM Upgrade Tool, select the newly appeared COM port. Click Open Serial and then click Download.
CRITICAL: You must keep the Power button held down until the progress bar reaches 100% and the flash is complete. Releasing it too early may cause the update to fail. 5. Finalize the Update
Once the tool indicates "Success," release the Power button.
Reboot the oscilloscope to verify the new firmware version, which is usually displayed briefly on the splash screen during startup. Important Troubleshooting & Tips
FPGA Mismatch: If you upgrade to firmware versions like V1.3.0C, you may also need to update the FPGA firmware to avoid "AUTO" button issues. This often requires an external programmer or a special microSD image to enter USB FEL mode.
Backup First: It is highly recommended to dump your current SPI flash before installing new firmware to ensure you can revert if errors occur.
Official vs. Custom: The official ZEEWEII site provides manuals, but community-driven projects like ZeeTweak on GitHub often offer more advanced functionality.
