get tftp ready to go (with the right build) so you only need to hit [enter]

CFE> flash -noheader : flash1.trx

start your tftp quickly

EDIT:

cfe> nvram erase [enter]

cfe> tftpd [enter]

now start the tftp utility using a wndr3300_mini.chk build

Looks like I'm back in business!!!! Yay! (I accidentally flashed a dd-wrt .bin the first time... that didn't work. Re-flashing with the .chk worked fine tho!)

Me too, thanks for all your help :-)

I'm all upgraded to dd-wrt.v24_mini_generic_16785.bin

I never did do an 'nvram erase' or a 30/30/30 reset though... oops! (I did choose reset all settings when I upgraded from the .chk build tho... ah well Wink). Seems to be working well, I'll just leave it now!
