I have a WRT54GL (ver 1.1) with Tomato 1.21.1515 I downloaded the latest tomato firmware 1.27.7z, and went to Administration>>Upgrade to select the file Tomato_1_27.7z. When I hit the Upgrade button though, I get the message: Expecting a ".bin" or ".trx" file I tried changing the name of the file to Tomato_1_27.7z.bin to upgrade, but then I get an error message: File contains an invalid header Please wait while the router reboots... Is there a simple way to upgrade the router to the latest firmware?
download this program to extract the binary. (its only a 40 day trial version but will work for you) http://www.megaupload.com/?d=9IFMZYBS
Yes, it does nag - something about not being free. I like it because it supports almost everything the Windows user is ever likely to come across, and it is very easy to use.
