I for one second this patch. I have just bricked my router trying to get the current trx image to work on my WNR3500L. I am not sure why it worked previously but it does not now, but it was doing just as described, hanging at "Starting program at 0x80001000". I thought it was because the MTD command had failed, so I tried from CFE and inadvertently overwrote my CFE - doh!
