MX5 Chinese to International Rom - corrupt

HI!
I have a chinese MX5 with the latest 5.1.11.1A firmware.
I tried to install G firmware with the “change id” method in terminal. I gave it root access, everything works ok, the device restarts after executing “chid.sh” command. I have the corresponding “chid” file for mx5 and still…Recovery says firmware corrupt when i try to install “G” firmware (update.zip on the root of the device).
Any ideas what i’m missing? I tried downloading the rom directly from the phone too. No difference.
Thank you

Meizu Pro 5

@tommyboy7 did the id really changed?

sorry for the possibly "stupid " question, but where can i check the id?

btw. also tried this method. No results!

Found the instructions here. I’m running the G firmware now , everything running smoothly.
