You need to use erase and sprogram to program the boot. The normal "program" will not work if the router is bricked,

Will the WRT54G4M target work on my wrt150n?
Same mappings?

I do not know. Check the flash size. If it is 4M then it should be something like 320 at the end. 160 will be 2M flash.

tap c
tap a ffffffff
(You should now see "DEBUG ON" on the lower right coner).
detect (You should now see the flash type. If not start over again.
ldram cfe
erase cfe
sprogram cfe
(I found slow program works better than the normal program on this modem. Possible because of the watchdog). erase kernel
sprogram kernel
erase nvram (sprogram/slow program)
Good better best

Looks to me this is good programming. But you need to make sure what you have programmed in is good backup. If not then it will still not work. Try to erase all the NVRAM and see if it is back to life.

I am not sure if the xml is right for your target. Maybe you need to study the memory map of WRT150N and see if WRT54G4M is right for you.

If you have any free time, and are willing, could you team view and help me out?

I can have a try but I do not have any WRT150 backup. Try to be in chat after 8:00pm pacific time and see if I am there.
