    tomato-K26USB-NVRAM60K-1.28.7495.2MIPSR2-Toastman-RT-VPN.trx
    That build is not to RT-N16 you shold use:
    tomato-K26USB-1.28.7495.2MIPSR2-Toastman-VLAN-RT-V PN.trx
    Try to restore with asus restoring tool.

    press and hold the Restore button when you plug the unit in....does the Power LED blink?
    If so...use the restoration utility from Asus to reflash the router with the .trx file.
    http://www.4shared.com/file/GL0aSSZ8/ASUS-RT-N16-RECOVERY.html?
    You will need to set a Static IP address on your computer and plug into the LAN port.


    btw: Tastman..... is Toastman :rolleyes:

    I've posted this many times!


    The ASUS RT-N16 does NOT have 60K of NVRAM.

    To use 60K the router's CFE must also support 60K. Linksys use a modified CFE, and that is why they work. The display will *show* more than 32K NVRAM available, but when you try to actually use it, you will brick the router. Usually, tftp or ASUS recovery tool will not work.

    I guess the OP's machine was fine for 2 weeks until he saved something to NVRAM that exceeded the 32K boundary.

    Please guys, only use the version that is recommended for your router! Not just the RT-N16, but ANY router!

    So, I used wrong toastman tomato version.

    Is there any other option to flash any firmware to my router? - Jtag is difficult option for me.

    Thanks for your answers.

    - Restore button
    - Jtag cable
    - Try CD comes with your router, need to be in recovery mode.

    I don't know which country you are in but in dd-wrt forum barryware help people with bricked routers. He have helped many sad users!

    I sent it back to asus for warranty last week. I'll see answer for next 30 days. If they disallow warranty than I will try Jtag. (sorry for my english

    OK, good luck, I think they'll fix or change it no problem.

    Anyone else who used a 60K NVRAM build on the wrong router, and got a brick, post in this thread please, as a reminder to others.

    Also, please some of you guys, use some common sense! If a router has 60K of nvram, please use a version for 60K - why keep asking if you can still use the 32K version? Why keep wasting everyone's time?

    I did the same mistake with my N16, mine is also no power LED light on. I RMAed it to ASUS. I live in USA. Sorry guys I am new and still learning stuff.

    I was so stupid. did not not read it properly before flashing it to 60K NVRAM. my N16 was working fine with old TOMATO USB beta version for about a year and halp.

    By the way I love Tomato firmware. Thanks for developing and maintaining such a great firmware!!

    Normally when you use a 60K version on an unsupported router and then overwrite the 32K nvram space, it is well and truly "bricked" and needs JTAG to recover. Often the serial port no longer gives any output. The ASUS recovery tool etc. usually doesn't work.

    To debrick an RT-N16 using jtag, you need the TJTAG program from Tornado of DD-WRT fame. Release 3.0.2 RC2 supported the RT-N16 but the unbuffered "simple" parallel port JTAG cable didn't work. It will work using buffered cables. This was fixed in RC5.

    Anyone wishing to donate 3.0.2 RC5 for router development, it would be appreciated..

    Hi Toastman,

    Thanks for the reply !!! I live in Chicago very close to barryware (I think!) . My router is still at ASUS service center, my router is still under warranty.
    I will try to get help from barryware if ASUS return my router without fixing it.

    I am not good with the TJTAG ..., not sure if I need to buy any hardware (tools ) to use these tools. Sorry, I am still in the learning curve.

    I have E3000 for now with Tomato on it, but I still prefer N16 over E3000. hoping ASUS replace my router!! :)

    Normally they do so.

    By the way, ever wondered where all these "refurbished" routers come from? LOL
     
  22. senthil

    senthil Networkin' Nut Member

    FYI - ASUS replaced my N16 with a brand new one!!

    Please confirm the version suitable for N16 is "tomato-K26USB-1.28.7495.2MIPSR2-Toastman-VLAN-RT-V PN.trx"

    Thanks for the help!!

    Yes.

    NB - VLAN builds are work in progress, if you do not need the VLAN-GUI/MultiSSID the standard build may be better for you.

    Now that I know that the 60K builds cannot be used on models that have 32K of NVRAM...

    For routers that have 60K of NVRAM, can you use either the regular or 60K builds?
     
  25. Dark_Shadow

    Nope regular builds for 32k nvram routers, 60k builds for 60k nvram routers.

    My problem is solved. Asus allow my warranty - so I have new router.

    THANKS for every help

    For now - you can setup your router with 60k, it will work, until restart, when first 32k stays, and last everything will be cleared (bootloader from asus or broadcom do that helpfull check :) ). As we can not know, what will be in second "illegal" part, we can lose some settings, or even router hangs on boot. As i tested this situation - router lose some of VPN sertificates and settings, and some of settings (hostname). It seems that are last modified (or added) settings. If you change some settings, required to boot, and they have to stay after 32k - brick is possible.

    Victek has an interesting solution. I don't know what he has done. I think if I am reading correctly in other posts. That he has gotten 60k to work on the Asus RT-N16. I haven't tried it as I am using shibby's release. Could someone clarify this?

    I'm thinking about that all - what to do ? Can VPN, virtual wi-fi, qos settings moved to jffs or usb partition ? NVRAM even 60k still real limit too...
    I can wrote some stupid script, that starts vpn with my settings, stored on usb disk, but that solution is not fine. But time to modify source/firmware will be multiplied with time to understand that all. I decided to ask Toastman for that :) Can you include in vpn server settings page little PATH variable, where settings will be stored ?
     
  31. kthaddock

    kthaddock Network Guru Member

    You can store your settings on USB /mnt like this:
    Code:
    ca /mnt/sda1/openvpn/ca.crt
    dh /mnt/sda1/openvpn/dh1024.pem
    cert /mnt/sda1/openvpn/server.crt
    key /mnt/sda1/openvpn/server.key
    tls-auth /mnt/sda1/openvpn/ta.key 0
     
  32. Vladimir Drabkov

    Vladimir Drabkov Serious Server Member

    yes, something like that i've mean with I can wrote some stupid script, that starts vpn with my settings , but from web-interface that things can not be set ? All what i need - vpn server can use "path" like /mnt/sda1/openvpn/ or what we like, that way it can be simple solved, or not?

    I am another who accidentally loaded the 60k on my RT-N16 :(

    I can get into recovery mode, and can tftp trx files, but when I reboot,
    the power light still flashes on and off (meaning it is still in recovery mode).
    I also tried ASUS Restoration Utility with stock firmware, and it loads the trx file,
    but when verifying "Auto System recovery is in progress", it stops at 33%;
    then rebooting results in recovery mode.

    Used the red button to reset nvram to default values. But that
    did not help.

    Any suggestions?

    update: 3rd time's a charm. On the third time using restoration util,
    I was able to access the web ui. And now I'm back :)

    Tip for people - usually the ASUS recovery tool does a good job. Some people have reported this tendency to stop at 33% (I haven't seen it myself) but just ignore that and continue. Be sure to wait for around 5 minutes before you restart the router, it seems most problems are caused by not waiting long enough.

    Some versions of the recovery tool have been reported as not working. There is one that is known to work on my 4shared download site.
