How to Update Radioddity GD-88 & DB25-D Firmware?
In general, an update of PC-software (CPS) or radio-firmware should only be done if it is really required, following the golden rule that "If it isn´t broken, don´t fix it!".
ⅰ. Prior to performing a firmware update, save the current codeplug to a file. After doing so, the firmware update may be applied. Finally, the previously saved codeplug should then again be written to the radio using the corresponding CPS.
ⅱ. This firmware update guidance works for both Radioddity GD-88 and Radioddity DB25-D
Before update, the following items are needed:
ⅰ. Programming cable
ⅲ. A computer running the Windows (XP/Vista/7/8/10/11) operating system
ⅳ. Download the firmware and update tool through Radioddity Download Page
ⅴ. Make sure the radio is with sufficient power / stable power supply
Firmware Update Steps
1.Install the Firmware Update Tool
To install the updater, just unzip the archive you downloaded from Radioddity support and double click on the file, named "IAP(setup).exe". This will install the firmware update program on your Windows machine and place a shortcut on your desktop.
2. Put the radio into firmwamre update mode
ⅰ. Turn off the radio.
ⅱ. Close the CPS (in case it had been running) in order to make sure the virtual COM-port of your programming cable is not occupied.
ⅲ. Connect your Radioddity GD-88 or DB25-D via the supplied programming cable to your Windows PC.
ⅳ. Press the [P1]-key on top of the Radioddity DB25-D and keep it depressed. For the Radioddity GD-88 it is the upper sidekey [P2] that needs to be kept depressed.
ⅴ. Additionally turn on the radio either by turning the volume key clockwise (Radioddity GD-88) or by pressing the "power key" left to the [P1]-key (Radioddity DB25-D).
ⅵ. The status-LED will constantly light up red.
ⅶ. On the Radioddity GD-88 a special screen will be displayd with either "IAP_A" or "IAP_B" shown in the top line. On the Radioddity DB25-D, the display will stay blank and backlight will be on, regardless of your normal settings.
ⅷ. Release the [P1]-key (Radioddity DB25-D) or the upper sidekey [P2] (Radioddity GD-88).
3. Start the update tool
4. Choose the virtual COM-port that does represent your programming cable
5. Click on "Open"
Note: If the update
tool connect to your Radioddity DB25-D or GD-88 successfully, it will output
"IAP Successfully". If it isn´t able to connect to the radio, it will stay on
CommPort:COM "x" (where "x" represents the selected virtual COM-port number of
your programming cable ). If you forgot to shut down the CPS, you will get a
"The COMM port is occupied or doesn't exit!" error.
6. Click on the button "Open APP file".
7. navigate to the path that does contain the update file that is intended to be transferred to the Radioddity DB25-D or Radioddity GD-88, such as:
ⅰ. Do not use update files intended for other radios, even if those radios may be looking like the Radioddity DB25-D or Radioddity GD-88. Using files not intended to be put on a Radioddity DB25-D or a Radioddity GD-88 may result in a loss of any guarantee
ⅱ. Whereas a firmware update for the Radioddity DB25-D
consists of just one file, the Radioddity GD-88 does require two separate files.
One for each independent VFO (A and B). To select the target location of the
file, long press the upper side key [P2] of the Radioddity GD-88 to switch
between "IAP_A" and "IAP_B". The firmware files are normally marked with "HAM_A"
8. To start the actual update process, click on the ‘IAP’ button.
Note: Do not press any key on the radio, do not remove power, just wait until the radio has finished the update process and turns off! During the update process, the status-LED will flash green and red and the application shows the progress by the increasing number of "Current Page".
As soon as the update has finished on the
Radioddity DB25-D, the radio will automatically shut down, whereas the
Radioddity GD-88 will state the following on its screen "Status: Rec Done!".
If you have just updated one of the two GD-88 VFOs it is now time to select the second VFO (long press of the upper side key) and update it with its corresponding firmware file as well. After you have updated both VFOs of the Radioddity GD-88, turn off the radio.
9. You may now normally power on the radio again.
