Default [Q] Need guidance flashing sammy based rom from aosp

I have an international version of s3. the first rom i had flashed was foxhound based on 4.1.2. after a couple of months, i decided to find other roms to run as my daily driver. flashed a bunch of roms til i come to know of slimbean. flashed the one based on 4.3. after a week or two, wanted to try ultimarom v16. i backed up, wiped everything like i used to before flashing but this time something weird happened. i didnt get all the customizations that the rom is offering, just some minor ones.
so, i was wondering if i had done something wrong and missing anything. tried flashing it again but there were no changes. an example of whats missing is the inability to set toggles on the notification shade. cant even change the tiles on on the shade as well.
its kinda weird cause i read thru the ultimarom thread and those stuff were suppose to be in the rom.

thanks for ur help!!
