Md9600-csv-2571v5--v26.45.bin -
Let’s parse the string into plausible segments:
Conclusion: The name likely results from accidental concatenation, e.g., md9600_firmware_v26.45.bin and csv_2571_v5 being merged, or a corrupted download from a Chinese or Russian radio forum where filenames sometimes include extra metadata.
This segment points to a specific Printed Circuit Board (PCB) revision. "2571" likely corresponds to an internal engineering drawing or assembly number. The v5 suffix denotes the fifth hardware iteration. This is critical: firmware for v5 may be incompatible with v4 due to changes in GPIO pin mapping or voltage regulators. The double hyphen (--) acts as a delimiter, separating hardware mapping from software versioning.
The version number v26.45 situates this firmware in the "Experimental" or "Unofficial" category.

The file "md9600-csv-2571v5--v26.45.bin" is a specific firmware version for the TYT MD-9600 (and its clone, the Retevis RT-90) digital mobile radio. It is primarily known in the amateur radio community as the essential "donor" file for installing OpenGD77—an open-source firmware that significantly improves the radio's usability. 1. Key Specifications & Identification Version: v26.45 (Released approximately May 2021).
Hardware Compatibility: Specifically for Version 4 (V4) and Version 5 (V5) hardware revisions, which use the newer 2571 PLL chip.
Warning: Do not attempt to load this on older V1, V2, or V3 radios, as the hardware change makes them incompatible and can cause unpredictable results.
CSV Designation: The "CSV" in the filename indicates this version supports the User Database function, allowing for a larger contact list (often up to 100,000+ contacts) by disabling the voice recording feature found in the "REC" versions. 2. Primary Use: The "Donor" File md9600-csv-2571v5--v26.45.bin
In most modern reviews, this specific .bin file is discussed as a donor file for the OpenGD77 Project.
Why it's needed: OpenGD77 cannot legally include the proprietary AMBE+2™ DMR codec. Users must provide this official TYT firmware file so the OpenGD77 installer can "strip" the codec and integrate it into the open-source firmware.
Compatibility: Interestingly, this same file is used as the donor for multiple radios, including the MD-9600, MD-UV380/390, and Retevis RT-3S. 3. Performance Review (Official vs. OpenGD77)

While specific changelogs for custom firmware can vary, version v26.45 typically aims to improve the user experience over stock firmware. Common enhancements found in this firmware branch include: Let’s parse the string into plausible segments:
Connect the programming cable to PC (not to radio yet). Install drivers. Ensure COM port appears in Device Manager.
The file md9600-csv-2571v5--v26.45.bin appears to be a firmware binary intended for the MD-9600, a VHF/UHF mobile transceiver manufactured by Retevis (or its OEM partners like TYT). The MD-9600 is a dual-band amateur radio that supports both analog FM and digital DMR (Motorola-compatible Tier I & II) operation.
The filename structure suggests:
Go to Menu → Radio Info → Firmware Version. It should show v26.45. Then write back your saved codeplug (older codeplug might be incompatible – if CPS refuses, you must manually reconfigure channels).
