Trouble Flashing Shibby from Asuswrt-Merlin on RT-AC66U

    Hello,

    I am currently running Asuswrt-Merlin (3.0.0.4.374.40_0) and I'm trying to flash with Shibby's build (tomato-RT-AC66U_RT-AC6x--116-AIO-64K.trx) on my ASUS RT-AC66U.

    Unfortunately, every time I try to flash, I get the following error: "Firmware upgrade unsuccessfully. It may result from incorrect image or error transmission. Please check the version of firmware and try again."

    Any ideas on how to resolve this?

    Thanks!

    Can you use the restore mecanism - in restore mode?

    I believe you need to use the restoration tool to go between ASUS-WRT and Tomato

    I assigned my machine a static IP (192.168.1.10), I put the RT-AC66U into rescue mode, and tried to load Shibby via the Firmware Recovery tool, but it says, "The wireless router is not in rescue mode".

    So, I flashed it with DD-WRT, then flashed it with Shibby (selecting the option to clear all settings). But, upon reboot, it would not respond at all. I can't get out to the WAN, can't ping it, nor can I access it via the web interface. What a nightmare! It didn't used to be this hard.

    I tried telnet-ing to my RT-AC66U, but there is no response.

    I tried putting it into rescue mode with the WPS button instead of the reset button, but it did not work. Any other suggestions? I fear I may have bricked it.

    Ugh! OK, I was finally able to flash my RT-AC66U successfully with Tomato (Shibby v 116). I wish I had just done this method from the start. Hopefully subsequent upgrades won't be as traumatic.

    "Put the router into recovery mode, set a static IP address on the computer then run in the shell:
    tftp 192.168.1.1
    binary
    put [filename].trx"

    I tried using the TFTP client on Windows 7, but I ended up having to use the TFTP client on my MacBook. Not sure why.

    Windows 7 doesn't doesn't let you immediately access devices connected over ethernet. There is enough of a delay that you will miss the window for a successful tftp flash. XP didn't have this problem/feature (all a matter of perspective).

    The problem is (likely) that windows 7 take a few moments to recover when the ethernet port comes up. One solution that I've found is to use an ethernet hub or switch between the router and the computer. I know it sounds more than a little redundant, but it works.
