    Hello community!

    I have successfully flashed Tomato FW on my Netgear WNR3500Lv2. I decided to return to OFW, however I accidentally flashed WNR3500 instead of WNR3500L (downloaded from Netgear official WWW)...

    I've read this article and couple of threads:

    I've tried 30/30/30 resetting. I get 3 ping responses from router right after powering on. I've tried tftp but get timeout error all the time (I guess response window is too short).

    So I guess I need USB-TTL cable and try to run TFTP mode on my router like in the article above? Shipment from Amazon en eBay would be pain in the ass to Poland, so I have to order from Allegro. This cable would be OK (it has to be 3,3V right)?

    Is there still hope for my router to get back to life? Is Netgear warranty covering such situations?

    Regards and hoping for your help!

    tftp takes patience and works best from an OS other than Windows Vista/7/8. There are posts in this forum on how to get it working in those OS's, but I find it easier to use a PC with XP or *IX (eg. Linux). If you are getting responses to ping then you will likely eventually have success with tftp over ethernet.

    You can ping router for 3 seconds after turning it on because the router starts TFTP client and asks TFTP server on for vmlinuz file. That means CFE is alive. :D And no, renaming firmware.chk to vmlinuz doesn't work, it ends up with "PANIC: out of memory" on the serial console. Only way to unbrick WNR3500Lv2 is through serial console. I've rigged my one up using RaspberryPi, if you have one nearby, you don't need to buy USB serial cable.
