New User with ERPoe-5 and dreaded v1.2 firmware

Hello All,

Band new user of ERPoe-5 running v1.2 (unfortunately). The issue encountered is the dreaded "ER-e100.v1.9.0.4901118.tar82.9MBUpload failed" from the web GUI, and getting an error from the CLI as well... 

Admin@WAN-Router:~$ add system image http://dl.ubnt.com/firmwares/edgemax/v1.3.0 /ER-e100.v1.3.0.4605130.tar

I have searched on the problem, and I KNOW how to fix it... Have to get firmware onto the router and install locally, as the add from URL isn't working due to the curl issue... 

Found answer to WHY this happens here:

Used this for help:

So at this point I am sitting here, and still fairly a noob with linux command line, I am not exatcly sure HOW to move the config from my computer to the router. Any assistance would be GREATLY appreciated!!!
