Anytone AT-D890 / Bridgecom Maverick / BTECH DA-7X2 Leaked 1.03 Firmware Update Instructions
Disclaimer: Perform the tasks below at your own risk as I do not accept any responsibility should you have an undesirable outcome.
For those doing this update with the Bridgecom Maverick, or the BTECH DA-7X2, the radio in the end, after using this update, will essentially be an Anytone AT-D890UV. Now, that sounds drastic, but really it’s not. In this instance you can’t compare the two because they are the same internally. As a ham that I know said, it’s the same girl, with a different dress and name tag. One radio is blue, the other is black. That is where the differences end.
Ok, with that out of the way, here is the procedure I use to make the required updates to the radio, as well as a link to a generic codeplug for those in west-central Florida.
- Changing the mode of the radio – When the radio is new and is shipped to hams, they have been arriving in Mode 007, which limits the radio to Amateur Radio frequencies only. The VHF is set for 144-148 MHz, and the UHF is set for 420-450 MHz.
The codeplug for this radio that I have setup is set for the radio to be in mode 000. This will allow the radio to be used VHF 136-174 MHz, and UHF 400 – 480 MHz. The air band is available in either mode.
Those who are familiar with Anytone programming know that if the mode doesn’t match, using the Anytone CPS software, the codeplug won’t work for the radio you want to write it to.
So, there are two ways to do this, one is to use the procedure that M0FXB Andreas shows, and that is to hold the PTT along with the number 1 button, and then while doing that, turning the radio on. If you are better with videos for this process, check out Andreas video at https://youtu.be/y6iWQ1gKUXw?si=LfiB4nJndvXl6obk
Now, I have seen at least one radio that this didn’t work with, so, there is another method. By the way, here is a cheat sheet to move between different programming:
The other method is to use a program called AT_Options for the AT-D890UV. The program, when run, will allow you to change the mode with a program with the radio connected to the programming cable. A link to this program can be found at: https://delaney.rocks/downloads/AT_Options_D890UV-251226.zip
(Note: Moving forward it is important to follow the directions shown for each of these procedures. There are instructions in the original V1.03 CPS and firmware to complete each step, but follow the directions carefully).
Unzip the AT Options program file and you’ll see the .EXE file as well as modes.txt file which has the frequencies any of the settings for the radio that are available. As I mentioned before, we will be setting the mode to MODE 0.
Start the Anytone_D890UV_Option.exe program. A window will pop up when you execute the program. Change the COM port to the COM port your connected radio is on. (Your radio needs to be on at this point with the programming cable connected. Be sure to check the Device Manager in Windows so you know what COM port your radio is connected to).
Once your programming cable is connected, press the READ button, and it should read your radio in. More than likely, it will show that your radio is in Band 00007. If your radio did read in correctly, then change the Band to Band 00000. (Be advised, this is no issue if it is a new radio, but if you had a codeplug in there already, that will be wiped out.) Now, go ahead and select WRITE, to WRITE the new Band (Mode) back to the radio.
Now that your radio is in MODE 000, we can move on to the next step.
- Base Band 3288 Upgrade – In order to do this, we will need to now download the actual, non-NXDN, v1.03 firmware. All of the following updates, with the exception of the firmware update for NXDN, will come from this file. You can download this file at https://delaney.rocks/downloads/D890_V1.03.zip
You will want to extract the file and you will end up with folders titled A READ FIRST (which has the instructions you’ll use to do these upgrade, a folder for the base band 3288 update, a BT Firmware update (which we will NOT be doing), D890UV NR board upgrade, a D890UV 1.03 CPS (which we will not use), a D890_ICON_V101, and a folder titled D890UV 1.03 DMR firmware which we will NOT be using.
Now that you have this .zip file extracted, go to the folder titled “base band 3288 upgrade.” When you go into that folder, you’ll see another folder, as well as a .hex file. That .hex file is the one we will be using for the base band 3288 upgrade. Move one folder deeper into the SCT_3288 folder. There you will find a program called SCT_PORT.exe That is the file you will be executing. However, before you start that, be sure to go back to the A READ FIRST directory and either read on screen, or print, the file called “3288 base band upgrade.pdf” I am not going to run through those instructions in this document, they are all in that .pdf file. Follow those instructions as they are step by step and perform the Base Band 3288 Upgrade. One thing I will say, not all of these programs will give a task completed notification. To be safe, wait a minute or two after it appears the process is completed, before restarting the radio. - D890UV NR Board Upgrade – This upgrade program is located in the D890UV NR board upgrade folder. The actual file you will load into the program for his upgrade is in that folder, but the executable file is located one folder deeper in the JLUartUpdate folder. The file you will execute there is called JL Bootloader.exe You will also want to follow the directions carefully in the A READ FIRST folder titled “NR board FW upgrade instruction.pdf” Follow those instructions carefully.
When you execute the program it will seem a little daunting as the buttons in the program, are in Chinese. The instructions will show the button to press to load up the D890_NR_BOARD_V110_20250811.ufw file into the JL Bootloader program. After you see you have that file loaded into the JL Bootloader, you can then write it to the radio using the larger button on the lower right, in Chinese, to complete the NR Board Upgrade. It will give a 100% completed notification, in Chinese, but you’ll figure that out. Use Google Translate if you’re not sure. - D890UV Icon Update – Now we can move on to the D890UV Icon Update. The file needed for the update is in the D890UV_ICON_V101 folder, but you use the Anytone CPS software to do this. To perform this update, you could install the CPS program that was included in the zip file for all of these, but why not just load up the CPS program you’re going to use in the end, to perform this update, and that is the one that supports NXDN. So, at this point, go ahead and download the file at https://delaney.rocks/downloads/D890UV_v1.03-DMR-NX.zip
Go ahead and extract that file. When you do, go into the D890UV_v1.03-DMR-NX folder, then the D890UV_v1.03, and finally the D890UV V1.03 CPS folder. There you will find the D890UV_Setup_1.03.exe program. Go ahead and install that.
Now that the CPS is installed, go ahead and run the D890UV_1.03 program. You will use that for this process. The directions for this process are in the A READ FIRST folder and the directions are titled “Icon Update Instruction.pdf” Follow those instructions to complete the Icon Update. - The v1.03 Firmware Update that supports NXDN – We will, once again, load the CPS program, if not already running, that you installed from the file you downloaded with DMR-NX in the title. This last step will be used to write the firmware to the radio. Follow the instructions in the “Firmware Update Instructions.pdf” file and be sure you use the firmware that is in the D890UV_v1.03-DMR-NX/ D890UV_v1.03/D890UV_V1.03 firmware folder named “D890UV_V1.03_20251225.spi”
Once you’ve followed the instructions and installed this firmware, you’re now ready to load up your codeplug. - Loading the codeplug – the starting codeplug that needs to be customized for you in the DMR>Radio List, APRS, and NX Settings, can be found at https://delaney.rocks/downloads/Anytone_890UV_15FEB26.zip
When you unzip the .rdt file from the zip file you can use File, and Open, and once in the CPS, you can write it to the radio. Be sure to change the items in the DMR>Radio List, APRS, and NX Settings first.
At this point, you should be good to go! Enjoy NXDN
