ok , so , as far as i can understand from the google translated chinese flyme download page , there are 3 chinese versions names : a(public) , q(telecomunications) and m(mobile customization) .
for your case i dont see that anything can go grong if you try to straight instal the update.zip on the base of your internal storage . if the system reads it as an update file the rest will follow and you will be updated . otherwise it will just tell you that it is not recognised as an update file

I understand perfectly, mine came with the global rom on a Chinese version (serial number is 721M****) , looks like there are two different versions of Chinese variant (721q and 721m) and mine came with the later. global rom has been installed by the seller and my Id is now 721H. So from your explanation, I think I can go ahead to flash the Chinese rom. Thanks for your time.

READ FIRST
as said above if you have 721q you have to change id
if you have 721h you can vice versa between G and A with straight install
what is 721m?

hi, guys. Mine came with the global rom on a 721M. Can i also just install the flyme 7 beta rom by downloading the zip file and flashing same via recovery?

You don`t ned to change ID ,just flash it with claer data,you must change ID only in case if you have for example 721Q,and want to flash a global rom.

It will be needed change ID maybe on build.prop.

anyway in my case which i have an 721h with g rom and flashed A rom .
i went back to G just with straight flash the global rom i put in base of internal storage

it is a basic rule in any forum , in order the same question not to be asked and answered over and over to make a litle search inside the forum in your devices section and in faq section .
