) mobile DMR radio. It is most commonly used as a "donor" file during the installation of the OpenGD77 open-source firmware.
The OpenGD77 project requires this original file to extract the proprietary AMBE voice codec, which cannot be distributed directly due to licensing. 1. Preparation Before you begin, ensure you have the following: The Hardware: A TYT MD-9600 Retevis RT90
. Note that "v5" in the filename indicates this is for Version 5 hardware (often marked as hardware version 4A on the PCB).
Programming Cable: The standard USB cable that came with your radio.
Software: Download the latest OpenGD77 CPS (Customer Programming Software) from the OpenGD77 Downloads page. 2. Locating the Donor File
If you are installing OpenGD77, you don't actually "flash" this .bin file directly to the radio yourself. Instead, the OpenGD77 firmware loader uses it:
Download the md9600-csv-2571v5--v26.45.bin file (it is often included in "firmware software V4.3.6" ZIP packages from TYT). Save it to a known folder on your PC.
As noted in the OpenGD77 User Guide , the software will prompt you to "Select Donor File" during the installation process. Select this .bin file when asked. 3. Installation Steps
Enter DFU Mode: With the radio off, press and hold the two orange buttons (on the radio body, not the hand mic) while switching the power on. The screen will remain blank, but the LED may flash. Open CPS: Launch the OpenGD77 CPS on your computer. Flash Firmware: Go to Extras > Firmware Loader. Select your radio model (
The CPS will ask for the OpenGD77 firmware (usually a .sgl file).
The CPS will then ask for the Donor Firmware—this is where you select md9600-csv-2571v5--v26.45.bin.
Complete: Once the progress bar finishes, the radio will reboot into the OpenGD77 interface. Troubleshooting
No Audio/No Rx: If the radio reboots but you hear no audio, you may have used the wrong donor version. According to documentation on Zhihu , "v5" is for newer hardware. If your radio is very old (Version 2 PCB), you may need a Version 1 donor file.
Driver Issues: If the PC doesn't see the radio, ensure you have the STM32 Virtual COM Port drivers installed, which are typically bundled with the OpenGD77 CPS. AI responses may include mistakes. Learn more

The string MD9600-CSV(2571V5)-V26.45.bin refers to a specific "donor" firmware file used by amateur radio enthusiasts to install the
custom firmware onto various Digital Mobile Radio (DMR) handhelds and mobiles.
Here is a short story dramatizing the role of this specific file in the world of ham radio hacking. The Ghost in the Radio
Elara stared at the screen of her TYT MD-UV380. For months, the stock software had felt like a locked room—functional, but cramped. She wanted the freedom of the OpenGD77 project: the better interface, the deeper accessibility, and the legendary "whisper" mode. But to get there, she needed the key.
She opened the forum archives and scrolled until she saw the string of characters that felt like a secret incantation: MD9600-CSV(2571V5)-V26.45.bin
It was an odd requirement. She wasn't even using an MD9600 mobile radio. But the developers had explained it long ago—this specific file contained the "codec," the proprietary digital voice translator. Because of legal licensing, the open-source community couldn't include it. You had to "donate" it from an official TYT update.
"Extracting the donor," she whispered, her fingers flying over the keys.
She held down the SK1 and PTT buttons, clicking the radio on. The LED began its rhythmic dance—flashing red and green like a tiny signal fire. On her PC, the firmware loader sat waiting. She selected her custom build, then pointed the loader to the V26.45.bin The progress bar crawled across the screen.
It is highly unusual to receive a request for a "essay" on what appears to be a specific firmware file name: md9600-csv-2571v5--v26.45.bin. A standard literary or historical essay does not apply. Therefore, this response will treat the string as a technical artifact and deconstruct it in the form of an explanatory technical analysis, which is the closest academic equivalent for an engineering or cybersecurity audience.
| Risk Level | Area | Notes |
|------------|------|-------|
| High | Hardware mismatch | Flashing 2571v5 firmware on v4 or v6 boards may cause boot failure. |
| Medium | Version rollback | Many MD-9600 units block downgrading below a certain version (e.g., v22+). |
| Low | Malware risk | Uncommon in ham firmware, but .bin from unverified sources could contain malicious code (though no known cases for MD-9600). |
| Low | Transmitter damage | Firmware won’t directly damage RF hardware, but misconfigured registers could cause out-of-band TX if not restricted. |
