yep the jumper is there.

tried that as per the instructions documented in this thread [LimUtil --update scrogged - how to start over? - #2 by cswiger](https://discourse.myriadrf.org/t/limutil-update-scrogged-how-to-start-over/689/2)

FX3 → Program firmware to RAM.

Box pops up saying the limesdr will reset, please reconnect to it however it doesnt come back and dmesg shows it as disconnected but it doesnt reconnect

dmesg output:

[4473.095482] usb 3-1: USB disconnect, device number 8

not sure if this is relevant but im connecting it solely via usb , i dont have dc power connected to it (need to find a suitable dc power jack)
