I am having some strange issues with HairyDairyMaid's debricker utility and trying to write a new CFE to my wrt.  I totally noobed the router by trying to upgrade to RC6 with ipkg (I know, no need to rub it in)

Anyway, so I made a JTAG cable and I can read just fine.  I trying flashing an NVRAM and read it back and it works just fine.

Then I try flashing CFE.BIN and if I stop it at 25%, just before getting to the next block, I can read it back and everything is the same.  However, at 25%, it seems to go back to the beginning and hose the values that it just finished writing at the start of the CFE section.  I have tried various different things but nothing seems to work.  Can anybody out there help me?

PS - Also to note that if I erase the CFE, I can use ./wrt54g -flash:cfe.  After that, I have to use the /noemw flag until I erase CFE again.  Is that supposed to happen?

Thought I would post an update on this, in case anybody ever had a similar problem.  Turns out that a tiny piece of solder has fallen on the legs of the flash chip and bridged two pins.  Removing that allowed me to flash the router back to life.
