GS724Tv3 does not boot after firmware update
I recently purchased another used GS724Tv3 switch from eBay (I already have 2 others) and was in the process of updating the firmware to the latest 5.4.2.25 version through the web GUI as I have done...
I was in the same boat as you after bricking my GS724Tv3, and fortunately I found someone in the Netherlands who had a blog describing how to fix the issue. Netgear claims that there isn't a UART port on the device, but there actually is. Using a USB to TTL/Serial converter (runs you about $7 on Amazon), you can use a terminal program like PuTTy to access the switch, and flash over the original firmware for the device. From there, its a simple matter of using the GUI to work your way up the firmwares (making sure to flash all of the main revisions) and then you can get to the latest firmware.
HERE is the link to that webpage. If for some reason the link fails, do a search for Duteweerd Elektronica Reparatieverslag - Netgear GS724T V3 (English) and you can find step by step instructions.
Darren,
I noticed you said you were using a protocol analyzer. which one? what settings?
I've connected to my switch with a usb to serial converter and managed to get output to hyperterminal and putty. however all i get is gibberish. i've made sure that i've connected at 9600 to match prior posts. but i just get gibberish.
can you advise?
thanks,
joe
