Default [Q] samsung galaxy s3 mini g730a

Hi everyone,
I am trying to flash a custom ROM that I created (Android 4.2.2 downloaded from google repo and kernel downloaded from samsung opensource) to my SAMSUNG Galaxy S3 mini SM-g730a (AT&T). The problem is that this phone seems impossible to flash with unsigned or non-samsung roms!

I tried to upload boot.img and system.img through heimdall and it gives me an error (ERROR: Failed to confirm end of file transfer sequence!).

I tried to upload it with ODIN but gives me an error (Security check error)

I tried to create a zip with Android Kitchen and install it from the recovery mode and this time the error is about the sign of the zip. I tried to look for a customized version of recovery mode but I could not find one compatible with this phone. So, I cannot install it from the zip since I cannot sign the zip as samsung.

At this point I am tempted to take the phone and flush it in the toilet!!!

Any suggestion or anyone that could install a custom ROM?

Thanks
Marco
