Should I clear the NVRAM after this mistake?

    Haste makes waste. i accidentally flashed my NT-N66U with the wrong firmware (tomato-K26USB-1.28.0503.4MIPSR2Toastman-RT-N-VLAN-Ext.trx) which killed my connectivity upon rebooting.

    The fix I used was to enter recovery mode on the NT-N66U (holding down reset while powering it up... wait until the power light slowly flashes and release). I borrowed a Windows laptop from a friend and used the Asus recovery firmware flash utility to place on it, an older Shibby build (110 I believe) which was all I had access to at the time. Thankfully, this fixed it and allowed me access to the router. I then flashed to the correct build I wanted to originally (tomato-K26USB-NVRAM64K-1.28.0503.4MIPSR2Toastman-RT-N-VLAN-Ext.trx) and found that everything was fine once it rebooted.

    My question: should I clear the NVRAM and restore the settings manually of this mistake given what I have outlined above?

    Yes, because you changed between two firmwares (Shibby --> Toastman). They share many of the same settings, but it's not wise to always assume that (or that it will remain that way forever).

    It would take you less time to clear nvram and paste all the settings instead of writing 10 lines.

    Actually, I have quiet a bit of custom stuff... ended-up taking 30 min but it's done now. Thanks for the replies.

    Shibby's version and mine do have many differences, which involve nvram variables. Because of that, I would strongly recommend anyone doing this clears nvram. Most things will probably work but if you get strange things happen the temptation is always to blame one or other version.

    You can use this way of transferring settings:

    This is very nice, Toastman, thank you. It should be distilled out of the QOS discussion and made a sticky where most will see it.

    Some time ago one of the moderators/forum admins made stickies out of so many things that we couldn't see the forum posts! Strange thing is that if you put useful tips into a sticky called "Common tomato Topics) nobody looks at it. :eek:

    Tomato needs a wiki.

    Wikis are only useful if they are actively maintained, otherwise they become old outdated cruft that within 4-6 months causes more confusion than they do clarity. As someone who's written technical documentation both professionally and in the public domain, as well as someone who contributes to a couple wikis, trust me. :)

    TL;DR -- documentation is only as good as the time the maintainer has to put into it.

    Agreed... Tomato is such a power project, it does really need a single source of info, whatever that form might be. Relying on google and having to bring back multiple hits in order to compare the info and look for consistency is inefficient.

    There are already several wikis, some quite hard to find using google, most of them unmaintained and years out of date, often created by people with insufficient knowledge of the subject, with completely incorrect information that does nothing to improve people's knowledge. It would be a very good thing if they were deleted.

    The enthusiasm for maintaining a wiki soon wanes once the initiator realizes how much work it entails.

    For anyone who has the 25 hours a day necessary to do all of the things people keep demanding, do feel free to go ahead :D

    Long out of date and not very useful...
