Yes! Finally, I was able to recompile Rockbox 3.3 and the bootloader to support 4096 byte sectors and the 240gb Rockbox iPod is done!
I'd hate for others to have to go through that process themselves just to use Rockbox on their 240gb drives, so here are the files and installation instructions.
Here are the new files, hosted on RapidShare
Bootloader 3.3
RockBox 3.3
You will also need the
iPod Patcher, download the correct one (Win32, Mac OS X or Linux)
Installation of the new firmware and software is VERY simple.
1) Connect iPod, get it recognized. You may need to put it into disk mode first.
2) Download all the 3 file above and put them all into 1 folder.
3) Install bootloader using with commandline "ipodpatcher.exe -a bootloader-ipodvideo.ipod" (Win32 instructions, look at "iPod Patcher" link for Linux - you should be smart enough to know what to do if you're using Linux; for the Mac users, drop to a shell and do the same as the Linux people)
4) Unzip rockbox.zip to your iPod root folder
All done.
