Warning: Flashing the wrong firmware version for your specific hardware revision can "brick" the device, leaving you with a white screen. Where to Find Official & Community Firmware

Since the manufacturer (Zeeweii) doesn’t always maintain a centralized English portal, the community has stepped in:

EEVblog Forum: The go-to source for the latest stable releases and custom-patched firmware.

GitHub Repositories: Search for "DSO2512G-Firmware-Archive" for older versions if you need to roll back.

Official Seller Pages: Sometimes AliExpress sellers provide a QR code or Google Drive link for the latest updates. Step-by-Step Installation Guide 1. Prepare the Hardware

You will need a USB-C cable that supports data transfer (some cheap charging cables won't work). Most DSO2512G updates are performed via a virtual serial port or by dragging a .bin file into a mounted drive. 2. Enter Update Mode Most units follow this sequence: Power the device OFF.

Hold down the "OK" button or the "Auto" button (this varies by revision). Connect it to your PC while holding the button.

The PC should recognize a new drive named "Removable Disk" or "DSO2512G." 3. Flash the File Locate the firmware file (usually ending in .bin or .hex). Drag and drop the new file into the oscilloscope’s drive.

The device may disconnect and reconnect. Wait for the file transfer to complete fully. Power cycle the device. 4. Recalibration (Critical)

After every firmware update, you must recalibrate the device to ensure the zero-line is accurate. Disconnect all probes from the inputs. Select "Self-Cal" from the menu.

Wait for the progress bar to finish before touching the device. Troubleshooting Common Issues

White Screen after Update: You likely flashed a firmware version meant for a different hardware revision. Try flashing an older version or a "Universal" build.

Device Not Recognized: Check your cable or try a USB 2.0 port instead of USB 3.0, as some older bootloaders have timing issues with high-speed ports.

"File Too Large" Error: Ensure you are flashing a firmware file specifically for the DSO2512G and not its smaller sibling, the DSO1511. Conclusion

The DSO2512G is a powerhouse for the price, but it lives and dies by its software. Keeping your firmware current ensures you’re getting the most out of the 120MHz hardware. Always back up your current version if possible, and follow community threads closely for the latest "Gold Master" releases.

The most interesting "hidden" feature in the Zeeweii/SigPeak DSO2512G firmware is its undocumented overclocking mode, which allows you to manually widen the sample rate for better performance on higher frequency signals.  Notable Firmware Features 

Overclocking Mode: You can toggle this by entering the menu and holding the Aux + [Up] keys simultaneously. This pushes the device's sampling limits beyond standard factory settings.

Special Calibration Menu: In newer firmware versions, a long press of the Menu key grants access to a dedicated calibration interface. This allows for voltage and zero-point adjustments without needing the complex "power + button" startup combinations used in older units.

Custom "ZeeTweak" Mod: There is a community-developed firmware project called ZeeTweak on GitHub that adds several "interesting" capabilities not found in the stock software:

Arbitrary Signal Waveforms: Adds support for custom waveforms in the built-in signal generator.

Advanced FFT: Provides expanded FFT windows (Hann, Hamming, etc.) and automatic peak detection for up to 12 peaks.

Secret Debug Mode: Enables a "buffer dump" capture to pull raw data for external analysis.

Screenshot Repositioning: Recent updates fixed a common annoyance where the screenshot counter UI would block the actual waveform or cursor measurements.  Performance Note 

When using both channels, the firmware typically splits the processing power, reducing the bandwidth to 60MHz per channel. If you need the full 120MHz bandwidth, you must close channel two via the settings.
