    Hello,

    I have a Netgear 3500Lv2. I was using tomato-K26USB-1.28.0497.1MIPSR2-Toastman-VLAN-RT-N-VPN. Decided to upgrade to tomato-K26USB-1.28.0498.1MIPSR2-Toastman-VLAN-RT-N-VPN.
    Did a GUI upgrade and now everything is dead ;(
    The router does not respond to ping, all the lights are blinking in yellow. Did a hard reset several times, still no life in it.
    Please advise me how to revive the router.
    I used the .trx file to do the upgrade. Was this a mistake? Should i have used the .chk file???
    Please if someone had similar problem to share here...



    P.S. hello again my old friend (Buffalo WHR-HP-G54)!

    Try to run "ping -t 192.168.1.1 -w 10" and reboot, if there is a response or two then you need to time a tftp at that exact moment.
    If there is non then I guess you need to jtag.

    Thank you quietsy.I tried the following:
    1. 30/30/30 reset - The router is still dead.
    2. Did what you said, and after I plug it in, I only get 1 reply to my pings. The TFTP client says timeout error and I can't upload the image.
    3. I tried holding the reset button and plugging in the router. At the moment that I let go of the reset button I get 3 to 4 consecutive ping replies. But again after them only request timeouts and the TFTP client gives me again the timeout error.
    4. I tried for more than 60 minutes to flash it by starting the TFTP transfer at a different time, but to luck.

    Is there something else I can try, or may be I am doing something wrong from the 4 points above?

    I think you briked it. The WNR3500Lv2 builds specifically have "WNR3500Lv2" in the firmware name.

    Well if those two build weren't for this router, then how was it possible in the first place to flash the tomato-K26USB-1.28.0497.1MIPSR2-Toastman-VLAN-RT-N-VPN and it to work for 4 months?

    Can you please give me a link/name of the Toastman build that is for the 3500Lv2?

    But those are in .chk format. Those are only for the initial upgrade from stock FW to Tomato.
    After the initial upgrade, when upgrading from Tomato to Tomato the .trx format should be used.
    Am I wrong???

    You can use them. Never had a single problem. I have the WNR3500Lv2 as well. I have flashed every single build toastman has. I have upgraded from Toastman to Toastman. Shibby to Toastman and Toastman to Shibby. I never had a problem at all.

    But were you using the .chk or the .trx?

    I used whatever format it downloads in.

    There has often been confusion resulting from the names given to these routers. There's a WNR3500v2 and a WNR3500L v2 which have completely different hardware. If it ran the normal build before, then it isn't an L version, perhaps.

    Let's assume that it IS a 3500L v2. So it requires the special build.

    This file is on 4shared in .chk format

    tomato-Netgear-3500Lv2-K26USB-1.28.0497.1-Toastman-VLAN-RT-N-VPN.chk

    so my guess is that you flashed the wrong file.

    The procedure for recovery on this router is different. You cannot just tftp to it during a small "window" on startup as there is no tftp server running on the router.

    You must first access the router via the serial port, break into the cfe as it runs, and the enable tftpd, after which it's easy to flash new firmware. Here is a link to a full guide, thanks Pete!

    Will update you after the de-bricking takes place.

    @Toastman, yes it is 3500L v2 128ram.
    Being a Buffalo user for so many years, it was so compelling to flash the .trx file. My mistake entirely. :)
