Help flashing with Meraki MR24

Hello! I wanted to try flashing my old MR24 with openwrt but ran into issues. I followed this guide https://openwrt.org/toh/meraki/mr24#installation, but got stuck on step 4. Here are the errors I am getting. Could someone point me in the right direction?

where did this come from ?

Thats from my terminal, it displays commands twice. It only sends them once though

disable local echo ?

How would I do that? Also the issue is

ubirmvol: error!: cannot find UBI volume "part1"
                              
          error 2 (No such file or directory)
