dumping via LPT is highly unreliable. you should get a proper USB flasher.
I am using a maximus 360 NAND flasher to flash my 512 Jasper. Having said that I used LTP for my 16mb xenon and had no problems as long as my soldering was done right.
I was tring to find out if there is any benifit in erasing the MU, and, if it is recommended is the best way to erase the MU with this command:
nandpro usb: -e256/512 1001
