I just thought that I'd mention that some of these steps are already available in the form of the tools/update-tools/build-flash-fota.py script. I don't know the full details, but I've used that script to create a FOTA based update (albeit the one I created only had /system/b2g files in it). You should be able to create a full /system fota by using similar techniques. > On 03/19/2013 04:02 PM, lap wrote: > > Hey guys > > > > hm..because i can't flash the system.img to my device,so i am > > thinking > > about to make a rom package > > > > so i want to ask what do i need to put in the rom package?

The actual format of the system.img file may use yaffs or it may use ext4, or it may use something else. That's really phone specific. We build the system.img by packing up all of the files in out/target/product/PHONE/system directory, so there really isn't a need to unpack it. out/target/product/PHONE/system already contains everything completely unpacked.
