Radioddity GD-77 Flash Manager 1.0

Radioddity GD-77 Flash Manager is a utility designed to update and maintain the firmware and onboard data of the Radioddity GD-77 dual‑band DMR/analog handheld radio. It streamlines flashing firmware images, backing up the radio’s memory, and restoring data when needed—helping keep your device current and recoverable after unsuccessful updates.

Key features:

• Flash firmware to the GD‑77 and select compatible variants (compatibility may vary by model and hardware revision)
• Read, back up, and restore flash/EEPROM and calibration data
• Verify images to reduce the risk of corrupt writes
• Connects via the radio’s USB port; no separate programming cable required
• Provides clear progress indicators and logs for troubleshooting

Notes:

• This is not a codeplug editor; use the radio’s CPS to program channels, contacts, and settings.
• Ensure the battery is fully charged and the USB connection is stable before flashing.
• Some operations require bootloader mode; follow on‑screen prompts.
• Only use firmware images intended for your exact hardware and region. Flashing an incorrect image can permanently damage the radio.

Ideal for radio enthusiasts and technicians who need a reliable way to manage firmware and safeguard data on the GD‑77.
