EAP 225 Outdoor V1 - Installing Stock Firmware (Clarifications)

Good day, how can I reinstall the stock firmware of EAP 225 Outdoor V1?

Where do I need to run the code above.

I already made a back up file from this instruction

Looks like it's to be run on the same place you ran that other code ... since those files it refers to are still in /tmp/logdump

thanks. I will run it on ssh, right?

Cant run it on putty. no such file or directory

I used linux terminal command to produce the eap backup sysupgrade. Next step is to install it thru openwrt luci system upgrade right?

just keep going after the instructions that worked
