How to Update Xiegu G90 Firmware? | 2021 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.

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.

    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.

    Hi There,

    Trying to do the firmware update but when i hold space bar down and turn the G90 on nothing happens. Any idea what i might be doing wrong? Any advice is appreciated. Thanks Heaps

    To do this on a Mac load bootcamp and a clean copy of windows 7 to 10. Whatever your Mac will allow. Macs actually run Windows better than a lot of windows dedicated machines. Been doing this for years.

    I have been told there is a bug in FW v1.75 that puts the radio power level all the way to 20 watts on Tune, potentially causing damage if the antenna is too far out of resonance. Is this true? If so where can I get v1.74 to go back to until v1.76 is released to correct the bug?

    Just waiting for V 1.76 to get rid of 20 W showing when tuning that risks damaging rig and makes it illegal to use for a UK foundation license holder.
