How to Update Xiegu G90 Firmware? | 2024 Latest Guidance



This is the latest Xiegu G90 firmware update guidance for you all. With every new firmware releasing, more and more new features are available.

The following items are needed:
A. USB-to-Serial cable
B. G90
C. A computer running the Windows (XP/Vista/7/8/10/11) operating system
D. A 12-15V DC power supply (capable of supplying not less than 5A)
 

1. Install USB-to-Serial cable:
The very first thing is to make sure that the USB-to-Serial cable is working properly with the personal computer. The first time the cable is plugged into a USB port on the computer, the operating system will search for a driver file for this new hardware and automatically install the driver program. If all has gone well, we will be able to see the virtual serial port in the device manager program. If the driver file can’t be automatically installed by the operating system we will need to install it manually (driver files are available from the Radioddity G90 support page).

(Note: very early Xiegu USB-to-Serial cables used the Prolific Chip, currently supplied cables use a chip from FTDI, the old cables tended to be black in colour, the newer ones blue.)

After this action the virtual serial port and its port number will be visible in Windows Device Manager (which on the below computer you will see is COM6).

2. Wiring everything up:

2.1 Connect power cable

2.2 For updating the firmware in the head unit:

2.3 For updating the firmware in the base unit:




3. Update firmware via TeraTerm terminal software
(The program is supplied in firmware zip file from Radioddity if you don't already have it installed):
In order to transfer the firmware to the device, we use a serial terminal software program with XModem support called TeraTerm (other programs can also be used but this guide is for TeraTerm).

3.1 Install the TeraTerm terminal software

However, we are finding that some of the more aggressive Web Protection/Virus/Malware applications may be stripping the update and firmware files from the downloaded archive, or when the archive is extracted. The following link will allow you to download a certified virus-free Tera Term application used for the G90 update process.

RE: teraterm-4.105 https://tera-term.en.lo4d.com/windows

On any executable application, Right-Clicking on the app will open a selection box in which Run as Administrator is an option. Selecting Run as Administrator will ask for your permission to let the app make changes to your computer - Click YES

You will next see this:

Click on the I accept the agreement option and click Next


You will be given the option to accept the default installation location or Browse for a new one:

Click Next

Accept the defaults and click Next

Select Language and click Next

Select default or Browse for Start Menu Folder and click Next

Select additional tasks/options and click Next

Confirm installation options and click Install

Select Launch Tera Term and click Finish

3.2 Confirm your COM Port

Open Device Manager, Click on Ports (COM & LPT)

Observe Port number -- Right-click on the USB Serial Port (COMx) --x is the Com Port Number.

Select Properties, then Port Settings. Confirm Bits per seconds is 115200. Click OK

 

3.3 Configuration of TeraTerm

a) Select the serial port:

From the upper bar, select File/New Connection and then when the panel opens, the serial radio button.

This is where we enter the com port (COM5 in the below case, yours could be different) which we saw in Device manager earlier – select it from the list of available ports from the drop-down list.


 

 

 

b) Now we set the communications baud rate: Select Setup/Serial port.

Confirm the Speed is 115200 Click New Setting

c) We are now presented with the main terminal window:

 


 

d) Now ith G90 connected to a 13.8 Volt DC Power source capable of at least 6 amps current capacity, we start the G90 and want to enter the maintenance menu:

If updating from an early version of firmware to the current version press the space bar within the first 10 seconds of the start-up. If a normal boot occurs try again with the space bar on the computer held down and with the terminal program “having focus” i.e. selected.

If updating from a recent version of firmware press the volume button on the radio as you turn the radio on. Again, if this fails, try the process holding the space bar down and powering the G90 on.
Both of these actions interrupt the normal booting procedure and present you with a menu as shown below.

Why?

HOLD SPACEBAR DOWN and press G90 Power Button
(for G90 radios with Serial Numbers not containing the letter V as the prefix)


Press Volume Knob and power-on the Display Unit
(for G90 radios with Serial Numbers containing the letter V as the prefix (ONLY those containing a V as the first character of the Serial Number)
 

e) The firmware update menu will appear:

(When updating the main unit, there is a count-down timeout during which time you need to press 1 – when updating the display unit, there is no timeout, it waits for you).



 

Step 1: Press 1. Update FW

Step2: “Erasing.. 100%” and “Wait FW file...” will be displayed – the old firmware in the radio has now been erased and the menu is waiting for you to supply the new firmware code.
 


 

When the old firmware is erased and the message displayed is Wait FW File,

 

f) In Tera Term Click File → Transfer → XMODEM → Send In that order

Select Main Unit firmware update file (download the latest firmware of Xiegu G90), click Open

 

Check the 1K Option Box The transfer will not work if you do not do this!

 

g) The transfer will start loading

 

 

h) Wait until the transfer finishes

 

Once the transfer has successfully completed the G90 will restart automatically.


i) If you need to update both parts of the radio (head and main units)

Remove power count to 5 and reconnect power

Remove the plug from the rear and insert in the lower left-hand socket on the Display Head
 

If updating from an early version of firmware to the current version press the space bar within the first 10 seconds of the start-up. If a normal boot occurs try again with the space bar on the computer held down and with the terminal program “having focus” i.e. selected.

If updating from a recent version of firmware press the volume button on the radio as you turn the radio on. Again, if this fails, try the process holding the space bar down and powering the G90 on.
Both of these actions interrupt the normal booting procedure and present you with a menu as shown below.

 

Select 1 Update FW

When the TeraTerm displays Wait FW File

In this order, select

File

Transfer

XMODEM

Send

 

Select Display Firmware file

Place a Check mark in the 1K Box


 

Click Open

Loading……

 

Loading……

 

 

IGNORE THE LOST COMM Message if it appears

On Completion, remove power from the G90 and count to 5

Re-Connect power to the G90. turn radio on.


j) After restarting the radio, hold Function button in for 2 seconds, check the firmware levels through option 10 in the system menu.

    I suppose the first time updating is a little challenging, but having done it a few times, it is a pretty straightforward process now. I will say that I have scratched my head for several hours after appearing to brick my radio, only to discover that I neglected to check the box showing “1K” in the Teraterm file transfer window. It absolutely will give you issues if you forget that step.

    Otherwise I can update, downgrade or do whatever to both the display unit and the base without any problems now. The folks at RADIODDITY (thank you you all for your support and assistance) have been fantastic and they will be my goto source for any equipment that I would like that they carry. Special shout out to Echo for the quick follow ups and taking excellent care of me.

    What a chore and several email exchanges with Customer Support .to get V1.79 installed in both G90 main and display units. The install notes at one point calls out FINDME file associated with the TerraTerm File/Tansfer/Xmodem,/Send. FINDME allows the choice of main unit or display unit firmware to install. I never got that to work as advertised. Ended up using a copy & paste routine of Xiegu_G90_FW_V1.79b03_20221026_EN (1).zip to pull out main and display pieces. Success. Pressing the function key verified V1.79 firmware in the main and display units. Customer Support (Nora) was helpful along the way.

    Sure you can upgrade the G-90’s firmware but it’s far too complicated of a process to update ! I’ve done it and I know. G-90’s firmware upgrade should be a much more simple process like Icom uses on the 7300 or 705 or like Elecraft uses for their K3, KX3 or KX2.

    The latest firmware will disable the ability to adjust the left and right filters independently, It will revert to a “passband” adjustment. I tried older firmware and I was able to get the adjustment back but then the receive went totally dead. So I had to go back to the latest firmware but you can’t adjust the filters manually anymore, you just get passband adjustment. If anyone knows how to get the independent adjustment back, please let us know.

    My brother lives in a remote area of Idaho. When his G90 bricked he sent it to me hoping I could update the firmware. Support had recommended this. Instead, I did a factory reset and the radio works perfectly.
    My brother didn’t care about any of the updates, and he was simply happy to get the radio back in the same state he received it. So, factory reset may be an option for others, at least to get the radio working.
    Doesn’t require any computer access. Just hit the FCN button and then PRE to confirm. I had to try the sequence about six or seven times to catch it in time before the screen went blank. But eventually it worked and the radio came back to life.
