Questions on ROM development

I am able to extract System.img from the 4.4.4 ODEN install and mount it in Ubunto. I can modify the folders and files to remove bloat, etc. I am able to repack back and use FlashFire to flash the 4.4.4 modified firmware.

My question is related to 5.0. I have tried the same method and after several modifled attempts, was able to extract and mount the System.img. After debloating, etc. I tried to repack it the same way but in FlashFire, it fails the MD5 check.

I tried another approach. Instead of repacking the full firmware package, I just created the System.img as a stand alone flash-able package. I then install 5.0 through ODEN, install Root and FlashFire.

When I try to flash my modified System.img through FlashFire, it passes the MD5 and installs successfully but it never boots. It never even makes it to the initial boot screen.

After that, I have to ODEN back again and start over. Any dev's out there that might know what I might be missing or can point me to some documentation on the process for 5.0?
