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.
Hi darrenscott,
Welcome to the community! :)
It is not recommended to update the firmware from v4.1.0.9 then jump to the latest v5.4.2.25. The boot code should be updated as well when transitioning from the v4.x.x.x firmware to the v5.x.x.x firmware as indicated on this article. For me, it is more advisable to update the firmware in a ladderized manner. For example, since the current firmware is v4.1.0.9, you may update it to v4.2.0.11 then to v4.2.15 and so on until you reach the latest v5.4.2.25.
Kindly try to perform a factory reset on the GS724Tv3 then check if it would boot up normally. Observe the LED lights. If ever it boots up normally, check if you could still access its web-GUI. Let us know the results.

Hi DaneA
Thanks for your reply.
I wasn't aware of the limitations on upgrades to the firmware prior to attempting it - there is no mention of it in the release notes for 5.4.2.25, and I've never had any problems upgrading any previous GS724Tv3 switches I have. Had I known in advance I would have performed a stepped upgrade as suggested.
I've tried a factory reset on the switch several times and on restart it results in the power LED staying amber rather than green. I assume by factory reset you mean holding in the factory defaults button for a few seconds? If so, this appears to have no effect as the switch results in the amber power LED.
Is there anything else I can do to restore this switch to working order?
Thanks again for your assistance.
Regards
Darren
Hi darrenscott,
Kindly try the steps below:
1. Disconnect the GS724Tv3 switch from your existing network and make sure its turned on. Get a straightened paper clip.
2. Insert the paper clip to the factory defaults hole then press and hold the factory reset button inside it for 30 seconds.
3. After 30 seconds, turn off the GS724Tv3 switch while you still continue to press and hold the factory reset button. Wait for 5 seconds.
4. After 5 seconds, turn on the GS724Tv3 switch while you still continue to press and hold the factory reset button. Wait for another 5 seconds.
5. After 5 seconds, release the paper clip from the factory reset button. Check if the GS724Tv3 switch to boot up properly. Observe the behavior of the LED lights.

Hi again DaneA
Thanks for the detail instructions.
I have tried this 5 times just now, all with the same outcome...
- on powering on the switch, the power LED shows amber and all port lights are on (both green and amber)
- after a few seconds the port lights go out leaving just the amber power LED
- after a few more seconds all port lights come back on for a further few seconds
- the port lights then go out again leaving the amber power LED again
Are the steps you describe meant to restore the switch to a known state again? Can you think why following these steps is not having any effect?
Regards
Darren
Hi darrenscott,
Based on what you have observed, it seems that the GS724Tv3 switch got bricked that is why it won't boot up normally. You will need to have it replaced from the seller.
