Details

I am trying to use the last method mentioned on the ipodpatcher wiki page to write Rockbox directly into the OSOS image on my iPod Nano2G. Sometimes it works properly, but other times it fails saying that it couldn't read the header from the .ipodx file. I am following the instructions exactly, so that can't be an issue. I have tried hexediting the .ipodx file, and in some cases I can get ipodpatcher to read the header by editing the first four values, but this always causes a Checksum Error. Here is the exact output:

C:\Users\Michael Marley\Downloads>ipodpatcher.exe -wf rockbox.ipodx
ipodpatcher 5.0 with v4.0 bootloaders (v1.0 for 2nd Gen Nano)

Here is the .ipodx that fails.
