Thanks for supplying more information, now I have a better idea of how to help.
You should use the update-binary for your device, not the one ported,
All editing of the updater-script will need to be done in UNIX format, not windows as EOL differs, if your using windows be sure to use notepad++ and set it up properly,
I use 7zip normally not winrar but it shouldn't matter, you need to have compression set to store,
It has been years since I have tried to make a ROM in this fashion but I don't think much would have changed, the point your at now is to get it to flash (not get the ROM to work) this means you need to fix the status 7 error, which will be done by fixing your updater-script
If you want, post a copy of the meta-inf folder for your device and the one you are porting from an I can help further
