The Express does not follow standard kernel and ramdisk addresses.

To decompile the boot image:
Code:
unmkbootimg boot.img > info.txt
mkdir ramdisk
mv initramfs.cpio.gz ramdisk/initramfs.cpio.gz
cd ramdisk
gunzip -c initramfs.cpio.gz | cpio -i
To recompile, make sure you're still in the ramdisk folder, and do these to make the ramdisk:
Code:
find . | cpio -o -H newc | gzip > initramfs.cpio.gz
mv initramfs.cpio.gz ../initramfs.cpio.gz
cd ../
Now look at the info.txt you created earlier. At the bottom of 'To recompile this image...', there will be a mkbootimg command. Copy and paste that to your terminal, but before you hit Enter, add this just before '--base 0x80200000':
Code:
--ramdisk_offset 0x02000000
You may want to take a backup of the original boot image.

You are to fix the site?
You have an idea of when it will be fixed?
Or maybe somebody else can provide a temp upload? The site shows that the file has been downloaded over 200 times so someone must have it right? Xd

Got Goo to download. When I install CM 10.2 it sits on splash screen for about 20 seconds and then goes dark, double buzz and splash screen again. Not managed to change the boot image as yet. Not sure I can find time for that until Thursday.

Got my PC to boot to a 64 bit Ubuntu 13.10. Thanks to your tutorial @aureljared am having a go at building. What are you using to pack and unpack in Linux when you replace the boot image? Windows usually messes up.
