Do I use the BIN or the TRX file to flash??

    Hi,
    I have some Buffalo routers (they take the TRX with TFTP to flash) and some WRTGL routers which you can use the BIN file. My question, once you have a router that is running Tomato 1.xx can you flash to the new one using the TRX or must you still use the BIN file for the -GL series routers? For example, my WRT54GL is running v1.07. Can I upgrade to 1.17 using the TRX format or no? Is there any difference? It seems to accept both, I just want to make sure I am running the correct one... thanks :halo:

    Stock Linksys Firmware is very picky as to what it'll accept in the firmware "header" to prevent accidental bricking of router. 3rd party firmware doesn't care which firmware you choose.

    To be explicit: each of the .bin files are identical in content except for the small header at the front of the file that tells the Linksys upgrade process what version of router the firmware is designed for. That header is then stripped off and the underlying code is then flashed. This underlying code is what is stored in the .trx files.

    As szfong said, when stock Linksys firmware is installed, you have to pick the right .bin file to make sure the upgrade process is happy. Once 3rd party firmware is installed, it is assumed that you're not going to make a mistake like that and any .bin or .trx file is accepted.

    I like the way RonWessels explained it. I'm only a layman. :redface:
