Dead GSM7324 after Switch Recovery Tool?!
I purchased a switch second hand and was hoping to restore the software on it to get it back up and running. After getting the "unknown box topology" - seems common according to Google - I attempted ...
I guess the last poster isn't doing this for a production but rather his/her own fun if so I'm fine with sharing at least parallels I know about :-)
Although never done with a Netgear switch, as long as you get something on the prompt via serial which looks like the boot loader and you can enter it (only via serial console), you might try your luck with xmodem.
Cisco switches and router can often be be brought back as long their bootloader is still working, and their flash memory is not fried. It is the process of uploading the firmware via xmodem mode over your serial cable while the bootloader is put into xmodem mode to receive the firmware thsi way. The process *IS* slow, but might be you last resort if you want to give it a try.
If you are seriously interested in this, have a serial cable ready, read this link and try to understand it before trying.

A cross-lecture how this is done on other vendors can be helpful although escaping to the bootloader is different on Cisco to what I remember.
Good luck!
