UVMOD RX-TX

UVMOD RX-TX

This tool lets you create customized firmware Version 2.01.26 for the Quansheng UV-K5, UV-K6, UV-K5(8) and UV-5R Plus handheld radios. It spoof the fw version number (with *, 2, 3, 4) to make it flashable on all these walkie talkies. To flash the firmware, you need a compatible programming cable and the necessary drivers.

Usage

1. Select the desired mods and customize as needed. Refer to the description of each mod for usage instructions.
2. On the right side, you can select your radio model, but you can also leave it on "Patch for all radios", which creates a universal firmware that bypasses the version check.
3. Click "Patch" and watch the console output, it will show errors and also the final size. If you get an oversize warning, you will have to deselect mods that add extra memory and try again.
4. Click "Save" to download the finished firmware file.

Flashing directly with UVMOD

Modern Chromium-based browsers such as Chrome, Edge, and Opera have a built-in API that allows UVMOD to flash the firmware directly to the radio. This is the easiest way to flash the firmware, but it only works on Windows and Linux.

On Windows, you need the driver for the programming cable. Typically these cables use ch340, ch341 or cp210x chips. On linux, the driver is usually included.

1. Connect the programming cable to your computer and ensure the proper drivers are installed. It should show up as a com port.
2. On your radio (still disconnected and turned off), hold down PTT (large button on the side) and turn on the radio while still holding PTT. Now the flashlight should turn on while the rest of the radio stays dark. Your radio is now in bootloader mode.
3. Connect the programming cable to the radio.
4. Click "Flash directly" and wait for the process to finish. You can watch progress in the console.
5. All done, all your settings should still all be intact.

Flashing with the official software

If you use Windows, you can use the official updater tool. You can download it directly from UVMOD using the link in the console window.

1. Connect the programming cable to your computer and ensure the proper drivers are installed. In the device manager, it should show up as a com port.
2. Start the updater tool, select the com port, and click connect.
3. Load the customized firmware as the program file.
4. On your radio (still disconnected and turned off), hold down PTT (large button on the side) and turn on the radio while still holding PTT. Now the flashlight should turn on while the rest of the radio stays dark. Your radio is now in bootloader mode.
5. Connect the programming cable to the radio. The "Update" button in the updater tool should now become available.
6. Click update and wait for the tool to finish.
7. All done, all your settings should still all be intact.
