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.

I modified mkbootimg and unmkbootimg.
Download the tools by doing these in a terminal (I'm going to refer to my folder as tools):
Code:
[email protected]:~$ mkdir tools
[email protected]:~$ cd tools
[email protected]:~/tools$ git clone https://github.com/aureljared/mkboot_and_mkrecovery.git
[email protected]:~/tools$ cd mkboot_and_mkrecovery
[email protected]:~/tools/mkboot_and_mkrecovery$ ./copy.sh
The script copies the tools into your /usr/bin folder, but will ask for root permissions nonetheless.
Take note that you will be typing mkboot into the terminal, not mkbootimg.

Any progress, guys? =>

You know even though i wouldn't have a clue what I'm doing, i gave it another go, and even stuffed things up more than i did before, so I'm leaving it up to you guys, but at 64 I'm not afraid to give it a go.

Explain the problem, maybe we can make other developers understand and help, that we know from other phones and kernels.

Been doing a bit of experimenting. Flashed @KINGbabasula's rom and as reported stuck on the samsung splash screen, buzzes twice and reboots. Tried flashing a s4 mini kernel over it . Long shot but no joy.logic was as cwm came from the s4 mini and they are close cousins so might work.
Built my own cm10.2 using the tutorial provided by @aureljared using the KINGbabasula Git repository. First. Installed using the older cwm. Same result as KINGbabasula's rom. When i updated the cwm and had another go it gave me the same errors we saw on page 26 with assert failed. At least helps me spot errors in my build. Don't get the error with KINGbababasula's build.

Okay.
CyanogenMod automatically packages boot.img with its own kernel, right? Well, that kernel doesn't boot on this phone (I don't know why).
So far we have tried numerous builds, even got to the point of using the stock kernel, all to no avail. The events below simply occur when we try booting CM:
1) phone stays at phone logo, goes black, vibrates twice, and reboots only to repeat the process; OR
2) phone stays at phone logo, then screen slowly maxes out brightness making screen extremely hot (has to press and hold power to reboot)
Also, since our CWM is from the S4 Mini (which has extremely close specs to ours) repackaged with stock kernel and correct addresses, @bazzan here tried repackaging the boot.img with a kernel from a cm-10.2 build for serranoltexx (this is what you did, right?), also to no avail.
So right now we are stuck on rooted stock 4.1.2 with CWM 6.0.3.7.
Take note: mkbootimg does not use the same addresses as the stock boot.img.
* load addresses:
kernel: 0x80208000
ramdisk: 0x82200000
tags: 0x80200100
* cmdline = console=null androidboot.hardware=qcom user_debug=31
