#Sizes: 1619 for old firmware (mine - late 2012), 1620 for intermediate firmware (the QLD sat-nav unit which is 3 months younger than mine), 1630 for newest firmware from 2014
/packages/factory/core-pkg/nandWrite -n=64 if=/dev/etfs1 ibs=2112 of=/fs/usb0/core0.ifs obs=2048 skip=512 count=1620
/packages/factory/core-pkg/nandWrite -n=64 if=/dev/etfs1 ibs=2112 of=/fs/usb0/core1.ifs obs=2048 skip=3072 count=1620
/packages/factory/core-pkg/nandWrite -n=64 if=/dev/etfs1 ibs=2112 of=/fs/usb0/core2.ifs obs=2048 skip=5632 count=1620

You need to know the size [number of blocks] - or just pick 1630 to make sure you get all the data. The numbers are calculated by the original source size / 2048 and rounded up.

If I were to want to copy one of the good files into, say, the third position (including unlock and re-lock commands):

/packages/factory/core-pkg/send2 -t /dev/etfs1 9:108 3,4
/packages/factory/core-pkg/nandWrite -n=64 if=/fs/usb0/core0.ifs ibs=2048 of=/dev/etfs1 obs=2112 vbs=2112 pad=0xff seek=5632
/packages/factory/core-pkg/send2 -t /dev/etfs1 9:108 1,4

Geesh... I need a BEX and a good lie down!
