## LimeSDR WestBridge Corruption
If you're like me and you bought a LimeSDR at launch and haven't used it since 2018 and it's 2020 and beyond. You might have this problem where it doesn't work. It took me forever to find this shit, but it's this issue here regarding `WestBridge Corruption`. It turned out that the jumper was broken and not connction the FX3 Boot pins. I bridged them with some wire and everything works.

After the jumper was connected I just needed to do a `LimeUtil --update` to get my old ass device current.
