- new feature to reboot from android
- add credits/reference at the end of message

I managed to make working multiboot feature on Galaxy S3.
Below are some videos preview that I did demonstrating the features ( don't look at sound, I removed it because my english is not fluent).
This project is at an early stage but already working with limitations.
If you want to try it, beware that it is dangerous (no risk to brick but if you make mistake you risk to install a zip into your internal rom), so to test it, please follow exactly the operations in videos examples.
Very important recommendations to test :
The method used is an adapted kexec-hardboot method created by mkasic (http://forum.xda-developers.com/show....php?t=1266827), but with a complete replacement of kexec by another userspace program ( kload-harboot ) and a very small kernel patch ( hardboot-reserve ).
- BACKUP all your data first !
- Use only your internal if you have at least 4G available ( 7GB recommended because I create sparsed img files but if you fill all the rom, it will take 7GB )
- Use your external sd card only if :- you have at least 7 GB free- Very very important : when you use "set rom" option, you have to see "command succeded" at the end of the output. If not, don't go further and reboot.
- your filesystem is vfat or ext4 ( exfat,ntfs not supported for the moment )
- start by playing with recovery roms ( check video ) before testing full rom
- creating rom on vfat can take about 15 minutes (to create img files). Be patient...
Note also that this adapted method is easily portable to any android devices.
If you are interested in this project ( to help for testing, to help dev, to add features etc..), I will open a thread in the developpement subforum, to published sources and explanations.
