[yay]

What os are you using? I use windows 7 and I know that the ext2 partition does not even show when my phone is plugged in my computer.
I made the exact same assumption but I realized that I could not extract nothing to the ext2 partition through windows because it is not even available. This is what led me to extract to the fat32 and run the npkinstall from there.

Hope this helps. I actually plan to install the new build tonight. I have to start from scratch and create my partitions again so i'll let you know how it goes.
