It is working now. I'm preparing an easy guide with an image.

As I'm typing this, I'm backing up my mmcblk0p* partitions.

The best thing, you don't even have to modify your recovery partition

I've written the guide here: https://wiki.merproject.org/wiki/Sai...prebuilt_image

As you can see I'm really not good at this kind of stuff. If some one with some skill in mediawiki wants to improve feel free. For questions use this thread or write me a pm.

Please be careful, I won't take any responsibility for your actions. This guide is for users who know what they are doing
