0x400004 seems low...
this was the output from i think was after erase output.... i am now not shure.
what are the better value?

and this here are not so tranparent.....

erase 0x9f050000 +0x00760000
cp.b 0x80000000 0x9f050000 0x400004

How do I get these values from where. also your link that you post here are not transparent about this values for me. so the second AP will also crash/trash!?

this come from modprob table?

I don't lose anything but it would be nice if it worked with the 2nd start

Question is where did you get them ?
EDIT: seems you picked the wrong wiki guide when you used
