[Q] How to package a lollipop update file - OS Porting

I read somewhere that Google has changed the system used for the standard update zip file.
Therefore you have to convert some .dat files to .img files and .img files to a standard readable folder.
This I understand, however how do I reverse the process above to get back to the .dat file and get a lolipop compatible flashable zip?

Lollipop ColorOS apps

would anyone please share their System\Apps folder. I tried downloading the whole ROM package but its a .dat file. I also managed to convert into an image file but did not succeed.
You need to convert .dat file first to .ext4 see HERE and then you have to use ext4_unpacker_exe.zip to extract the apps which you need
I already do this before few days Good luck!

Hi,
I want to create a flashable zip file for the G4, so I wanted to know if I need to extracted the boot/modem partition (for the Genesis G4 rom) with jest extracting the .kdz file and then just removing the .bin extension?

Unable to extract zip files inside of rom.zip

Hi all,
I needed original Build.prop, Boot and stock recovery from my RUU package. I successfully extracted the zip file from .exe file. But I found many zip files (about 25 zip files) in the rom.zip and I couldn't extract any of those 25 zip files. Is there any way to un-zip those files to get stock files to use later?
