Bricked Netgear M4300-52G (GSM4352S) via "Erase Permanent Storage" from CLI

[AWENA]

Hello, accidentally deleted the Permanent Storage via CLI

found this article but it didn't help:
https://alastair.d-silva.org/bricked-netgear-m5300-switch-erase-permanent-storage
   m4300r2> fatload usb 0:1 ${loadaddr} /boot.stk 
   Unknown command 'fatload' - try 'help' 
 
I understand that must execute the following command: "ubifsload"
but I don't know the syntax options "<addr> <filename>"
Please, help

Now I have the following in terminal:

Thanks for the answer. But isn't there any instruction: how to restore software? 
I read the NETGEAR CLI user manual, but did not find the information I needed, maybe I was looking in the wrong place?

I had the same problem and stumbled upon this thread.  I had luck recovering from the same state by following the steps in my post here:

https://community.netgear.com/t5/Managed-Switches/Recover-from-uboot-interface-on-M4300-52G-GSM4352S...

My method did require a TFTP server, but theoretically the other methods to transfer files should work too.  I think my biggest hurdle was figuring out the proper load address which I finally got by printing the environment before issuing other commands.  That got me to the operational code utility and then doing a "Load Code Update Package" restored the switch to an operational state for me.
