[Q] URGENT HELP in making a flashable Stock Rom extracted from HTC RUU.

I am beginner to android ROM development. i am at learning stage. I want to make a stock rom of HTC Explorer in a zip format so that it can be flashable through CWM. Here is the steps i am following:

Manually installing GApps.

Hi, I have an android device with a custom recovery, I also have the ROM package and I can flash the system directory using the recovery, and I can modify the contents of the ROM package and then flash it, I want to add to this ROM GApps, I've downloaded the GApps package,
It has the folder /system and META-INF that includes the installation script updater-script.sh, The ROM package also have updater-script.sh.
1. Is if it possible to install GApps on to this ROM by copying the contents of updater-script.sh of GApps into the updater-script.sh of the ROM package and copying the contents of /system of GApps to /system of the ROM package?
2. Should I be worried about ROM's META-INT signature files? (CERT.RSA,CERT.SF,MANIFEST.MF)
Thanks.

Hi, I have a device with custom recovery that can update ROM using update files, I got a working update file (zip contains system/ and META-INT/), When I'm unzipping it, add files to it and zip it again then flashing it, I get update failed, I even get update failed when I'm just unzipping and zipping without adding files or touching the content in the zip. Does anyone know why it might happen?
Thanks.
