Hi @j4mbob,

OK, one more thing to try - using Cypress tools. Check my post please:

> Hi @rene, If you got an interrupt during the FX3 firmware update, then you have to use Cypress tools to program it. Refer to sections 5 and 5.2 from this [resource](https://wiki.myriadrf.org/LimeSDR-USB_User_Guide#Flashing_the_USB_3.0_microcontroller) to update the firmware. Download the latest firmware [here](https://github.com/myriadrf/LimeSDR-USB_FX3/blob/master/Debug/LimeSDR-USB_fx3_fw.img).
