Im trying to make a ROM dump to get recovery, boot img etc. 

I used romdump v72 and the commands given but everytime I try it, I get

[1] Segmentation Fault     /system/bin/romdump

I dont know what that means? Am I doing something wrong?

I put following command :


su

cat /sdcard/install >/data/local/install
chmod 04755 /data/local/install
/data/local/install
 
and then turn wifi off and on and off,

then this one:

/system/bin/romdump


As instructed...but then I get that segmentation fault message...
I end up with a 'FROYO.JP3' folder, but nothing in it.

Can someone help?
