Not working after programming

[GhostDog98]

I am using the bluefruit LE sniffer, after installing openocd, I make this config file:

source [find interface/stlink.cfg]
transport select hla_swd
source [find target/nrf51.cfg]

I then run:

> reset halt
target halted due to debug-request, current mode: Thread 
xPSR: 0xc1000000 pc: 0x00002c78 msp: 0x20003248
> nrf51 mass_erase
Mass erase completed.
A reset or power cycle is required if the flash was protected before.

> verify_image firmware.hex

Despite this, once plugging in the device, I cannot see anything in /dev/ for new serial devices, making it impossible to run the tool.
I have tried doing this in both "switch" modes for the device
Upon connecting the device, i see the following in dmesg:

[221093.727301] usb 1-2: new full-speed USB device number 18 using xhci_hcd

As per issue #21, I have tried to recompile the firmware, however, that is not working for me (error: 'str' object has no attribute 'decode') and as the yotta GitHub is depreciated, I'm unsure about if I could even get help with this.

I have also tried the programming instructions on that issue, with no success.

Incase it is of any significance, I am using the V3 of adafruits bluefruit LE sniffer.

I bought a microbit version 2.20, it was completely flashed, but after running -s it does not show any output. Help me please

This is unrelated to the current issue thread, maybe open another issue with more information instead?
