This software is based on several open-source tools, allowing users to:
- Modify the embedded boot image/text in the G90 firmware.
- Encrypt/Decrypt firmware use user provided key
- Take a brief look at the firmware info
- Flash firmware into G90 series Rigs (g90updatefw integrated)
- ......
This software should work on windows/linux/macos but I only tried it on ubuntu 24.04
Important
The official Xiegu firmware is encrypted using the AES-256 algorithm, making it nearly impossible to decrypt without the key. Fortunately, there are open-source methods available to extract the encryption key using an ST-LINK debugger and OpenOCD tools. Due to copyright restrictions, I cannot provide the key here, but you can extract the encryption key and decrypt the firmware using the methods outlined in G90Tools or by finding the key shared by others online.
