I can confirm that Justin (@ratmandu) had a similar issue and was able to fix his x6100 using the method described by Franco (flashed the decrypted x6100 firmware to 0x8020000) along with a simple STM32 bootloader that he wrote (simple bootloader flashed to 0x8000000). Justin gave us his simple bootloader for others to use as well, which is now downloadable from along with some instructions.
If you need a new STM32 chip, I believe you’d be looking for a?

The encrypted STM32 baseband firmware is a file whose extension is .xgf in the '/usr/firmware' directory in your X6100; for instance the one for the latest version is called 'X6100_BBFW_V1.1.8_240915003.xgf'.
You can also find it in the sdcard.img file from a Xiegu X6100 upgrade zip; it is in the second partition under '/usr/firmware'.
